Direct coupling between servo electric motor and worm gear is among the crucial strengths of EP worm gearmotors, which combine DC engine technology with exceptional toughness and wear resistance. Electric motor and gearbox were created as one single, compact unit. Because of their reduced current draw, 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 on this we can select a wide variety of regular customizations to meet the requirements of various properties that are important for each application.
If your application takes a gearbox with some special property such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with more than 1000 different standard gearboxes is most likely a good begin to have the ability to deliver a product that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric electric motor is included with the gearbox right into a single unit (the first equipment is directly on the motor shaft). Separate gearboxes for link with conventional IEC motors can 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 happy to help you make your selection. We are happy to send you documentation or design a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our success came from our relentless drive 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 engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. 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-Power Worm gearboxes provide high torque with low speed 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 qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear units are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. As a result 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 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 high gearing capacity enables smaller tires to be used for the same torque, and smaller sized gears with exceptional power density can also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
