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 varied 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 with regards to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture 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 in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox 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 in 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 request.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. 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 design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite lengthy in the axial path. The gears in these gearboxes can be right 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.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear devices are designed 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. As a result our geared motors tend to be 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 style in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be used for the same torque, and smaller gears with remarkable power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft mounted and helical worm gears for a high 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
