Direct coupling between servo motor and worm gear is one of the crucial strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional toughness and wear resistance. Engine and gearbox are designed as one single, compact unit. Because of their reduced current draw, 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 our flexible modular concept.
Based on this we are able to select a wide variety of regular customizations to meet up the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special residence such as 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 combination of such properties, our product range with an increase of than 1000 different standard gearboxes is probably a good begin to have the ability to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric 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.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our professionals will be pleased to help you create your selection. We are happy to send you documentation or design a suitable set directly, on demand.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and engine 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 acceleration gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its body is generally quite long in the axial path. The gears in these gearboxes can be correct 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 (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear units are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse installation 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design 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 utilized for the same torque, and smaller sized gears with extraordinary power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary for troublefree rolling contact to be substantially decreased and then the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as regular in parallel shaft, shaft mounted 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
