Direct coupling between servo engine and worm gear is one of the key strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional strength and wear resistance. Electric motor and gearbox were created as one single, compact unit. Because of their reduced current attract, these gearmotors deliver more accurate control of working temperature and higher efficiency.

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 upon 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 takes a gearbox with some special residence such as small dimensions or low weight with regards 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 this kind of properties, our item range with an increase of than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox into a single device (the first equipment is on the motor shaft). Separate gearboxes for link with conventional IEC motors can 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 make your selection. We will be happy to send you documentation or design the right set directly, on demand.

Special wishes possible
Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor 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 velocity 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 are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite long in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect 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 elements for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear devices are built 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. Consequently our geared motors tend to be 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 by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with 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 allows smaller tires to be used for the same torque, and smaller gears with remarkable power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play 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 used as standard 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
