Immediate coupling between servo motor and worm gear is one of the crucial strengths of EP worm gearmotors, which combine DC engine technology with exceptional toughness and wear resistance. Motor and gearbox were created as one single, compact unit. Because of their reduced current draw, these gearmotors deliver more accurate control of operating temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based on this we can select a wide variety of standard customizations to meet the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special property 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 combination of this kind of properties, our product range with an increase of than 1000 different standard gearboxes is probably a good start to be able to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is built-in with the gearbox into a single unit (the first equipment is directly on the electric 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 happy to help you make your selection. We will be happy to send out you documentation or design the right set directly, on ask for.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of Compact Worm Gearbox mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm version, 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 rate gear ratio. Being basic and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option 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 components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, producing them much sought after in the industry. Consequently our geared motors are often to be found as part of 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 ensures optimum rolling get in touch with under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be utilized for the same torque, and smaller gears with excellent power density can also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling contact to be substantially reduced and then the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are used as regular in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
