Direct coupling between servo engine and worm gear is among the key strengths of EP worm gearmotors, which combine DC motor technology with exceptional sturdiness and wear resistance. Motor and gearbox were created as one single, compact unit. Because of their reduced current pull, these gearmotors deliver more accurate control of operating temperature and higher efficiency.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based upon this we are able to select a wide selection of regular customizations to meet the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special home such as for example small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good begin to be able to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox right into a single unit (the first equipment 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 create your selection. We will be happy to send out you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be a business 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 inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low speed gear ratio. Being simple and compact in design, these gears can achieve 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 can be correct 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 (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products are designed to withstand the toughest industrial applications.
The gear 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 guarantees optimum rolling contact 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 enables smaller wheels to be utilized for the same torque, and smaller sized gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
