We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps 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 standard customizations to meet up the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special home such as for example small dimensions or low weight in relation to electricity, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, tension or temperature, integrated linear screw, or a combination of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good start to be able to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is integrated with the gearbox into a single device (the first gear is directly on the motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our professionals will be pleased to help you create your selection. We will be pleased to send out you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for level of quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, produces the Ever-Power worm gearbox the default decision for the sector. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Ability Worm gearboxes provide large torque with low swiftness gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be proper or left-handed dependant on the purpose.
Mounting choice include universal housing, side 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-Electricity gearboxes and geared motors are the electro-mechanical key elements for low backlash, easily 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 permit diverse mounting positions and applications, producing them much popular in the industry. As a result our geared motors tend to be to be found within our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller gears with extraordinary power density can also increase reliability. Ever-Electrical power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Dual chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
