We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based about this we are able to select a wide selection of common customizations to meet up the requirements of various properties that are important for each application.
If your application requires a gearbox with some special real estate such as small dimensions or low weight in relation to electrical power, high efficiency, quiet and vibration-free operation, extended 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 an increase of than 1000 different standard gearboxes is most likely a good start to be able to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric electric motor is included with the gearbox into a single device (the first equipment is directly on the electric motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our specialists will be happy to help you make your selection. We will be happy to send out you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless travel for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, produces the Ever-Power worm gearbox the default personal preference for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Vitality Worm gearboxes provide substantial torque with low swiftness gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively larger) and its own body is generally quite lengthy in the axial path. The gears in these gearboxes can be suitable or left-handed dependant on the purpose.
Mounting option include universal housing, side 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-Electrical power gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear products are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much popular in the industry. Because of this our geared motors tend to be to be found within our customers own machines.
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 style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This excessive gearing capacity allows smaller wheels to be utilized for the comparable torque, and smaller sized gears with excellent power density also increase reliability. Ever-Electrical power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing enjoy required 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 utilized as standard on parallel shaft, shaft mounted and helical worm gears for a high 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
