Direct 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. Motor and gearbox were created as you 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 business lead screw / ball screw adapted to your flexible modular concept.
Based upon this we are able to select a wide variety 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 home such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, extended life, high level of 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 start to have the ability to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric motor is built-in with the gearbox into a single device (the first gear is on the electric motor shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our experts will be happy to help you make your selection. We are happy to send out you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came 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 wide choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. 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 velocity gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, side 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 are the electro-mechanical key elements for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, making them much sought after in the industry. Consequently 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact 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 enables smaller wheels to be utilized for the same torque, and smaller sized gears with extraordinary 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 perform required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are used as regular in parallel shaft, shaft mounted 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
