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 at this we are able to select a wide variety of typical customizations to meet up the requirements of varied 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 electrical power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, tension or temperature, integrated linear screw, or a combination of this kind of properties, our item range with an increase of than 1000 different standard gearboxes is most likely a good start to have the ability to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric motor is built-in with the gearbox right into a single device (the first gear is directly on the motor shaft). Individual 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 professionals will be pleased to help you make your selection. We are pleased to send out you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless get for level of quality with state-of-the-art technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, produces the Ever-Ability worm gearbox the default choice for the industry. 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-Electric power Worm gearboxes provide huge torque with low rate gear ratio. Being basic and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite long in the axial path. The gears in these gearboxes could be proper or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electricity gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly 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, making them much sought after in the industry. As a result our geared motors are often 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be utilized for the exact torque, and smaller gears with exceptional power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling contact to be substantially decreased and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
