Immediate coupling between servo electric motor and worm gear is among the essential strengths of EP worm gearmotors, which combine DC engine technology with exceptional toughness and wear resistance. Engine and gearbox are designed as one single, compact unit. Thanks to their reduced current pull, 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 lead screw / ball screw adapted to your flexible modular concept.
Based on this we can select a wide selection of regular customizations to meet the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special property such as for example 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 such properties, our product 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 regular drives. The electric electric motor is integrated with the gearbox right into a single unit (the first equipment is directly on the motor shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our professionals will be pleased to help you create your selection. We will be happy to send you documentation or style a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. 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 achieve higher gear ratio compared to 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 generally quite lengthy in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear units are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse mounting positions and applications, producing them much sought after in the industry. As a result our geared motors are often to be found within 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 combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be used for the same torque, and smaller gears with outstanding power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially decreased and therefore the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft installed and helical worm gears for a high 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
