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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based at this we are able to select a wide variety of normal customizations to meet up the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special property or home such as for example small dimensions or low weight with regards to ability, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, force or temperature, integrated linear screw, or a combination of this kind of properties, our item range with more than 1000 different standard gearboxes is most likely an excellent start to be able to deliver a product that stands out on your side.
Small gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox into a single device (the first gear is on the engine shaft). Individual gearboxes for connection to conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our experts will be happy to help you create your selection. We will be happy to send you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our success came from our relentless get for 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 electric motor interfaces, makes the Ever-Ability worm gearbox the default determination for the industry. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide huge torque with low quickness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite long in the axial direction. The gears in these gearboxes can be ideal or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Ability gearboxes and geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, producing them much popular 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 backed 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 materials used and surface finish maximizes load capacity. This substantial gearing capacity allows smaller tires to be utilized for the exact torque, and smaller gears with outstanding power density also increase reliability. Ever-Electric power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are used as standard for 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 devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
