Based on this we are able to select a wide variety of standard customizations to meet the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special property such as small dimensions or low weight in relation to ability, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure 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 have the ability to deliver something that stands out on your side.
Small gearboxes are high-top quality gearboxes for regular drives. The electric electric motor is integrated with the gearbox right into a single device (the first equipment is on the electric motor shaft). Individual 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 inside our e-shop. Our experts will be happy to help you create your selection. We are pleased to send you documentation or style the right set directly, on ask for.

Special wishes possible
Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless travel for level of quality with state-of-the-art technology, all and will be offering worm gearboxes happen to be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, makes the Ever-Electrical power worm gearbox the default decision 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-Electric power Worm gearboxes provide substantial torque with low acceleration gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial direction. The gears in these gearboxes can be best or left-handed dependant on the purpose.
Mounting choice 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.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear models are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. As a result our geared motors are often 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 contact under load.
The special tooth root style 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 used for the same torque, and smaller gears with outstanding power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are utilized as standard through parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
