A cautious evaluation in the situations surrounding a conveyor is necessary for accurate conveyor chain variety. This part discusses the basic concerns required for profitable conveyor chain selection. Roller Chains tend to be applied for light to moderate duty material handling applications. Environmental problems may possibly require using distinctive materials, platings coatings, lubricants or even the capability to operate with no added external lubrication.
Essential Information and facts Required For Chain Variety
? Type of chain conveyor (unit or bulk) such as the system of conveyance (attachments, buckets, through rods and so forth).
? Conveyor layout together with sprocket places, inclines (if any) as well as the number of chain strands (N) to get applied.
? Amount of materials (M in lbs/ft or kN/m) and style of materials to become conveyed.
? Estimated excess weight of conveyor elements (W in lbs/ft or kN/m) including chain, slats or attachments (if any).
? Linear chain pace (S in ft/min or m/min).
? Environment by which the chain will operate like temperature, corrosion circumstance, lubrication affliction and so forth.
Stage 1: Estimate Chain Stress
Use the formula under to estimate the conveyor Pull (Pest) then the chain stress (Test). Pest = (M + W) x f x SF and
Check = Pest / N
f = Coefficient of Friction
SF = Pace Component
Step two: Produce a Tentative Chain Variety
Utilizing the Check value, create a tentative variety by picking a chain
whose rated functioning load higher compared to the calculated Test worth.These values are acceptable for conveyor services and therefore are diff erent from people shown in tables with the front from the catalog which are related to slow pace drive chain utilization.
On top of that to suffi cient load carrying capacity frequently these chains has to be of the specified pitch to accommodate a desired attachment spacing. As an example if slats are to get bolted to an attachment every one.5 inches, the pitch from the chain picked must divide into 1.5?¡À. So one could use a forty chain (1/2?¡À pitch) with all the attachments just about every 3rd, a 60 chain (3/4?¡À pitch) using the attachments every single 2nd, a 120 chain (1-1/2?¡À pitch) with all the attachments just about every pitch or a C2060H chain (1-1/2?¡À pitch) with the attachments just about every pitch.
Stage three: Finalize Variety – Calculate Real Conveyor Pull
Just after creating a tentative assortment we have to verify it by calculating
the actual chain stress (T). To do this we will have to fi rst determine the actual conveyor pull (P). From your layouts proven on the suitable side of this page opt for the ideal formula and calculate the complete conveyor pull. Note that some conveyors may be a blend of horizontal, inclined and vertical . . . in that case calculate the conveyor Pull at every single section and include them with each other.
Stage four: Determine Maximum Chain Stress
The maximum Chain Stress (T) equals the Conveyor Pull (P) as calculated in Phase three divided from the quantity of strands carrying the load (N), times the Pace Issue (SF) proven in Table two, the Multi-Strand Factor (MSF) shown in Table 3 and also the Temperature Element (TF) proven in Table four.
T = (P / N) x MSF x SF x TF
Step five: Test the ?¡ãRated Doing work Load?¡À from the Selected Chain
The ?¡ãRated Operating Load?¡À from the picked chain should really be better compared to the Maximum Chain Tension (T) calculated in Stage 4 above. These values are proper for conveyor services and are diff erent from these proven in tables with the front in the catalog that are linked to slow pace drive chain utilization.
Stage six: Check the ?¡ãAllowable Roller Load?¡À on the Selected Chain
For chains that roll within the chain rollers or on leading roller attachments it truly is essential to check out the Allowable Roller Load?¡À.
Note: the Roller load is determined by:
Roller Load = Wr / Nr
Wr = The complete bodyweight carried from the rollers
Nr = The quantity of rollers supporting the weight.
Leaf Chains are created for large load, slow velocity tension linkage applications. Often these are specifi ed for reciprocating motion lifting units this kind of as fork lifts or cranes. These chains are normally provided to a specifi c length and therefore are linked to a clevis block at each and every finish. The clevis might accommodate male ends (inside or from time to time termed “articulating” links) or female ends (outdoors or the backlinks on the pin hyperlink) as demanded (see illustration beneath)
Leaf chains can be found in 3 series; AL (light duty), BL (hefty duty), or LL (European common). For new selections we propose the BL series in preference to your AL series as the latter has become discontinued as a recognized ASME/ANSI typical series chain. BL series chains are generated in accordance together with the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are made in accordance with the ISO 606 international leaf chain typical.
A chain with an even amount of pitches usually features a one male and one particular female finish. It can be far more prevalent to possess the chain possess an odd variety of pitches during which case the each ends is going to be both male (most typical) or female (significantly less com-mon). When ordering lengths with an odd variety of pitches male ends are supplied unless of course otherwise noted. Clevis pins, usually with cotters at every single finish, are made use of to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not constantly) linked to the clevis block that has a cottered form connecting hyperlink. The connecting hyperlink is the female end element in this instance.
Leaf Chain Choice
Utilize the following formula to verify the variety of leaf chain:
Minimal Greatest Power > T x DF x SF
T: Calculated Highest Chain Stress
DF: Duty Component
SF: Service Factor
Note that the optimum allowable chain speed for leaf chains is 100ft per minute.

Designers can opt for the series that best fi ts the individual desires of the application. These chains ought to be specifi ed only when conditions prohibit using lubricating oil due to the fact, on the whole, a nicely lubricated normal chain will off er longer existence compared by using a maintenance cost-free chain. In some applications having said that lubrication isn?¡¥t feasible and so using a self lubricated or sealed roller chain is important.
Standard Properties of Maintenance Free Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of the friction produced among the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which may hold a higher volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction created amongst the pin and bushing as the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller website link plates are a single size thicker to increase strength. Side plates and pins have special coatings to prevent rust.
C-Type Roller Chains
Similar as over except the side plates are all common thickness. The strength with the CS Type chains is less than the PT Kind but greater compared to the SL type. Attachments with typical dimen-sions can be utilized for this series and therefore they are usually utilized on small material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to maintain lubricating grease in when preventing the penetration of filth and various contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in although preventing the penetration of dirt and other contaminants in to the pin/bushing bearing region.

Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Usually these chains are similar to ASME/ANSI standard merchandise except that the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Normal (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
This series is usually utilized on drives with slow to reasonable speeds, reduced chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 for the ASME/ANSI chain number along with the prefi x letter ?¡ãA?¡À. Note that some businesses don’t use a prefi x letter for this series so the chains may well be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is usually used on light to reasonable load material managing conveyors with or devoid of attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. website link plates of the up coming bigger chain dimension. The chain variety is located by incorporating 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on a conveyor track lowering friction. Chain numbers are located within the identical way as noted over except the final digit to the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
In general sprockets really should be developed specially for these chains according on the ASME/ANSI B29.three and B29.4 specifications even so, for Transmission Series and Conveyor Series with Conventional (tiny) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may be utilized presented the number of teeth is thirty or much more.
The next methods should really be utilized to select chain and sprocket sizes, establish the minimal center distance, and determine the length of chain needed in pitches. We’ll principally use Imperial units (such as horsepower) within this segment nevertheless Kilowatt Capability tables are available for each chain size in the preceding part. The variety process may be the very same irrespective of your units used.
Step one: Decide the Class with the Driven Load
Estimate which on the following very best characterizes the ailment of your drive.
Uniform: Smooth operation. Small or no shock loading. Soft get started up. Reasonable: Regular or moderate shock loading.
Hefty: Severe shock loading. Regular begins and stops.
Step two: Establish the Service Issue
From Table 1 under identify the suitable Support Factor (SF) for that drive.
Step 3: Determine Design Energy Requirement
Style Horsepower (DHP) = HP x SF (Imperial Units)
Design and style Kilowatt Electrical power (DKW) = KW x SF (Metric Units)
The Design Energy Requirement is equal for the motor (or engine) output power instances the Services Element obtained from Table 1.
Stage four: Produce a Tentative Chain Variety
Make a tentative choice of the necessary chain size inside the following method:
1. If using Kilowatt electrical power – fi rst convert to horsepower for this phase by multiplying the motor Kilowatt rating by one.340 . . . This really is required since the fast selector chart is proven in horsepower.
2. Locate the Style and design Horsepower calculated in stage 3 by reading up the single, double, triple or quad chain columns. Draw a horizontal line by way of this value.
3. Locate the rpm on the modest sprocket around the horizontal axis in the chart. Draw a vertical line as a result of this worth.
4. The intersection on the two lines should really indicate the tentative chain choice.
Phase 5: Decide on the number of Teeth to the Little Sprocket
As soon as a tentative choice of the chain dimension is produced we have to decide the minimal amount of teeth expected over the little sprocket essential to transmit the Layout Horsepower (DHP) or even the Style and design Kilowatt Power (DKW).
Step six: Ascertain the amount of Teeth to the Significant Sprocket
Use the following to determine the amount of teeth for your huge sprocket:
N = (r / R) x n
The amount of teeth within the big sprocket equals the rpm from the tiny sprocket (r) divided through the preferred rpm from the massive sprocket (R) occasions the amount of teeth around the smaller sprocket. In the event the sprocket is also significant to the space readily available then a number of strand chains of a smaller sized pitch really should be checked.
Stage 7: Figure out the Minimum Shaft Center Distance
Utilize the following to determine the minimum shaft center distance (in chain pitches):
C (min) = (2N + n) / six
The above is often a guide only.
Stage eight: Examine the Last Choice
Also bear in mind of any potential interference or other room limitations that could exist and adjust the assortment accordingly. Generally one of the most efficient/cost eff ective drive makes use of single strand chains. This is often because numerous strand sprockets are far more costly and as is usually ascertained by the multi-strand components the chains come to be less effi cient in transmitting energy as the amount of strands increases. It can be thus commonly finest to specify single strand chains every time achievable
Stage 9: Determine the Length of Chain in Pitches
Make use of the following to calculate the length on the chain (L) in pitches:
L = ((N + n) / two) + (2C) + (K / C)
Values for “K” can be located in Table 4 on web page 43. Keep in mind that
C is definitely the shaft center distance provided in pitches of chain (not inches or millimeters and so on). If the shaft center distance is regarded within a unit of length the worth C is obtained by dividing the chain pitch (in the similar unit) through the shaft centers.
C = Shaft Centers (inches) / Chain Pitch (inches)
C = Shaft Centers (millimeters) / Chain Pitch (millimeters)
Note that every time feasible it can be very best to make use of an even amount of pitches as a way to prevent the usage of an off set hyperlink. Off sets do not possess the exact same load carrying capability because the base chain and should really be prevented if achievable.
