Direct coupling between servo motor and worm gear is one of the key strengths of EP worm gearmotors, which combine DC motor technology with exceptional strength and wear resistance. Electric motor and gearbox were created as you single, compact unit. Thanks to 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 lead screw / ball screw adapted to your flexible modular concept.
Based on this we are able to select a wide variety of standard customizations to meet the requirements of various 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 in relation 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 such properties, our item range with an increase of than 1000 different standard gearboxes is probably a good begin to be able to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric motor is integrated 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.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be pleased to help you make your selection. We will be happy to send out you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and motor 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 a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear products are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing 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 by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller wheels to be used for the same torque, and smaller sized gears with remarkable power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are utilized 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
