We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based with this we can select a wide selection of typical customizations to meet up the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special house such as small dimensions or low weight with regards to ability, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, tension or temperature, integrated linear screw, or a combination of such properties, our item range with an increase of 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.
Small gearboxes are high-top quality gearboxes for regular drives. The electric engine is built-in with the gearbox into a single device (the first equipment is on the 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 pleased to help you create your selection. We will be happy to send out you documentation or style the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes happen to be affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, causes 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Electricity Worm gearboxes provide large torque with low quickness gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be ideal 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 (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electric power gearboxes and geared motors are the electro-mechanical key components 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 popular in the industry. As a result 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 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 materials used and surface finish maximizes load capacity. This substantial gearing capacity enables smaller tires to be utilized for the same torque, and smaller gears with remarkable power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are used as standard on parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes and also Geared Motors
EP’s precision worm gearboxes will be made for those more demanding applications where small proportions, high torque, high ratio, low backlash, low sounds and long lifetime are required. Provided in 9 sizes, these worm gearboxes can be supplied with totally free input shaft, with hollow bore input shaft and engine flange, and double decrease combination units for slow swiftness applications. Working with cast iron housings, top quality bronze alloy worm tires and extended life bearings, reliability and functionality are the important top features of this range.
High Precision Right Position Transmission
Long Lifetime
WIDE RANGE Of Ratios
Special Surface Treatments
