Immediate coupling between servo motor and worm gear is one of the important strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional strength and wear resistance. Engine and gearbox were created as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver more accurate control of working 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 your flexible modular concept.
Based on this we can select a wide selection of standard customizations to meet the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special residence 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 item range with more than 1000 different standard gearboxes is most likely a good begin to be able to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox into a single unit (the first equipment is directly on the electric motor shaft). Separate gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our specialists will be pleased to help you make your selection. We are happy to send you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement 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 sector. 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 quickness gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting option include universal housing, aspect 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 components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear models are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much sought after in the industry. Because of this our geared motors tend to be 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact 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 allows smaller wheels to be used for the same torque, and smaller gears with extraordinary power density also increase reliability. Ever-Power geared motors are Compact Worm Gearbox therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are used as standard 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
