We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based on this we are able to select a wide selection of typical customizations to meet the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special property such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with an increase of than 1000 different standard gearboxes is probably a good start to have the ability to deliver a product that stands out on your side.
Compact gearboxes are high-top quality gearboxes for regular drives. The electric motor is included with the gearbox right into a single device (the first gear is directly on the engine shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be happy to help you create your selection. We are happy to send out you documentation or design the right set directly, on request.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, creates the Ever-Electrical power worm gearbox the default choice for the market. 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-Electric power Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes can be best or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Vitality gearboxes and geared motors are the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear units are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making them much sought after in the industry. Consequently our geared motors tend to be to be found as part of 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 ensures optimum rolling contact under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This excessive gearing capacity enables smaller wheels to be used for the comparable torque, and smaller gears with exceptional power density also increase reliability. Ever-Electricity geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard through parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
