We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based in this we are able to select a wide selection of common customizations to meet the requirements of various properties that are important for each application.
If your application requires a gearbox with some special property such as small dimensions or low weight with regards to vitality, 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 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 something that stands out in your favor.
Small gearboxes are high-quality gearboxes for standard drives. The electric engine is built-in with the gearbox right into a single unit (the first equipment is on the engine shaft). Individual gearboxes for connection to conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our specialists will be happy to help you create your selection. We are happy to send out you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success came from our relentless drive for level of quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Vitality worm gearbox the default personal preference for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Electric power Worm gearboxes provide great torque with low acceleration gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its body is generally quite long in the axial path. The gears in these gearboxes can be suitable or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Ability gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much popular in the industry. As a result 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This huge gearing capacity enables smaller wheels to be utilized for the equal torque, and smaller sized gears with excellent power density can also increase reliability. Ever-Electric 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.
Dual chamber shaft seals produced by Ever-Power are used as standard on parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
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 are created for those more demanding applications where small proportions, high torque, high ratio, low backlash, low noises and long lifetime are required. Provided in 9 sizes, these worm gearboxes could be supplied with free insight shaft, with hollow bore input shaft and motor flange, and double reduction combination units for slow swiftness applications. By using cast iron housings, high quality bronze alloy worm wheels and long life bearings, reliability and functionality are the important top features of this range.
