Direct coupling between servo engine and worm gear is among the important strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional durability and wear resistance. Motor 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 upon this we are able to select a wide selection 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 residence such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with more than 1000 different standard gearboxes is probably a good begin to be able to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric engine is integrated with the gearbox 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 in our e-shop. Our experts will be happy to help you create your selection. We will be happy to send out you documentation or design a suitable set directly, on request.

Special wishes possible
Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, 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 swiftness gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary 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, easily running and highly powerful drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making them much Compact Worm Gearbox 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 backed 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 materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be used for the same torque, and smaller sized gears with exceptional power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling contact to be substantially reduced and therefore the gear backlash to become minimized.
Dual chamber shaft seals developed 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 gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
