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 upon this we are able to select a wide variety of common customizations to meet the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special home such as for example small dimensions or low weight in relation to vitality, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a mixture of this kind of properties, our product range with more than 1000 different standard gearboxes is probably an excellent start to be able to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox right into a single device (the first equipment is directly on the engine shaft). Separate gearboxes for connection to 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 pleased to help you make your selection. We will be happy to send out you documentation or style the right set directly, on request.

Special wishes possible
Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless drive for level of quality with state-of-the-art technology, all while offering worm gearboxes happen to be affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Electricity worm gearbox the default personal preference for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Ability Worm gearboxes provide large torque with low speed gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be proper or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Ability gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much sought after in the industry. Because of this 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 by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be used for the exact torque, and smaller gears with excellent power density can also increase reliability. Ever-Electrical power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are utilized 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 programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
