Immediate coupling between servo motor and worm gear is among the essential strengths of EP worm gearmotors, which combine DC motor technology with exceptional durability 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 effectiveness.

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 upon this we are able to select a wide variety of regular customizations to meet up the requirements of varied 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 this kind of properties, our item range with more than 1000 different standard gearboxes is probably a good begin to have the ability to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for regular drives. The electric motor is included 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.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our experts will be pleased to help you make your selection. We will be happy to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art 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 market. The helical-worm and the double-worm edition, with or without the torque limiter, 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 achieve 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 body is generally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single 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 systems are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, producing them much popular in the industry. As a result our geared motors are often 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 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 materials 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 extraordinary power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially reduced and then the gear backlash to end up being minimized.
Dual 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 equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
