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 at this we can select a wide selection of normal customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special property such as for example small dimensions or low weight in relation to electric power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, tension or temperature, integrated linear screw, or a mixture of such properties, our item range with an increase of than 1000 different standard gearboxes is probably an excellent 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 integrated with the gearbox into a single device (the first gear is on the engine 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 create your selection. We will be pleased to send you documentation or design the right set directly, on request.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless get for quality with state-of-the-artwork technology, all while offering worm gearboxes happen to be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, causes the Ever-Electrical power worm gearbox the default determination 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-Electric power Worm gearboxes provide large torque with low acceleration gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like 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 could be proper or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear systems are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse installation positions and applications, making them much sought after in the industry. Because of this 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 materials used and surface finish maximizes load capacity. This substantial gearing capacity enables smaller wheels to be used for the equal torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard during parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes & Geared Motors
EP’s precision worm gearboxes will be created for those more demanding applications where compact specifications, high torque, high ratio, low backlash, low sound and long life time are required. Provided in 9 sizes, these worm gearboxes could be supplied with totally free input shaft, with hollow bore insight shaft and motor flange, and double reduction mixture units for slow velocity applications. Working with cast iron housings, top quality bronze alloy worm wheels and extended life bearings, reliability and performance are the essential top features of this range.
High Precision Right Angle Transmission
Long Lifetime
Wide Selection Of Ratios
Special Surface Treatments
