Direct coupling between servo electric motor and worm gear is one of the important 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. Thanks to their reduced current attract, these gearmotors deliver more accurate control of working temperature and higher performance.

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 are able to select a wide selection of standard customizations to meet up the requirements of various properties that are important for each application.
If your application requires a gearbox with some special house 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 mixture of this kind of properties, our product range with more than 1000 different standard gearboxes is probably a good start to have the ability to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric motor is built-in with the gearbox right into a single unit (the first gear is on the electric motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our specialists will be pleased to help you make your selection. We are happy to send out you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art 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 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 high torque with low velocity gear ratio. Being basic and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite long in the axial path. The gears in these gearboxes can be right 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 (one or double), 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, efficiently running and highly powerful drive systems.
Our high-performance gear models are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, making them much sought after in the industry. Consequently our geared motors tend to be to be found within our customers own machines.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the materials 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 excellent 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 play necessary for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are utilized as regular in parallel shaft, shaft installed 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
Precision Worm Gearboxes & Geared Motors
