Immediate coupling between servo electric motor and worm gear is one of the crucial strengths of EP worm gearmotors, which merge DC engine technology with exceptional strength and wear resistance. Engine and gearbox were created as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver more accurate control of working temperature and higher effectiveness.

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 in this we are able to select a wide variety of regular customizations to meet up the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special residence such as for example small dimensions or low weight with regards to electric power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our product range with more than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric motor is built-in with the gearbox into a single unit (the first equipment is directly on the electric motor shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Because of 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 will be happy to send out you documentation or design the right set directly, on request.

Special wishes possible
Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless travel for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, creates the Ever-Electrical power worm gearbox the default personal preference for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Electrical power Worm gearboxes provide great torque with low speed gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial path. The gears in these gearboxes can be proper or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electrical power gearboxes and geared motors will be the electro-mechanical key components for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. Because of this our geared motors are often 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 get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This excessive gearing capacity allows smaller tires to be used for the comparable torque, and smaller gears with exceptional power density 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 play required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to be minimized.
Dual chamber shaft seals developed by Ever-Power are used as standard during 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 systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
