We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based on this we are able to select a wide variety of regular customizations to meet the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special residence such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our item range with more than 1000 different standard gearboxes is probably a good begin to have the ability to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is built-in with the gearbox right into a single unit (the first gear is directly on the engine shaft). Individual gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our experts will be pleased to help you create your selection. We will be happy to send out you documentation or style the right set directly, on request.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively larger) and its body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, part Compact Worm Gearbox flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making them much popular in the industry. Consequently our geared motors tend to be to be found within our customers own machines.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with exceptional power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to be minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
