Direct coupling between servo engine and worm gear is one of the crucial strengths of EP worm gearmotors, which combine DC motor technology with exceptional toughness and wear resistance. Electric motor and gearbox were created as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver more accurate control of operating temperature and higher performance.

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 on this we can select a wide variety of standard customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special house such as small dimensions or low weight in relation to electrical power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a combination of such properties, our item range with an increase of than 1000 different standard gearboxes is probably an excellent start to have the ability to deliver a product that stands out on your side.
Compact gearboxes are high-level of quality gearboxes for regular drives. The electric engine is integrated with the gearbox into a single unit (the first gear 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 inside our e-shop. Our specialists will be pleased to help you create your selection. We are happy to send out you documentation or style the right set directly, on request.

Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success came from our relentless travel for top quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, would make the Ever-Electric power worm gearbox the default decision for the sector. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Electrical power Worm gearboxes provide substantial torque with low swiftness 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 characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes can be correct 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 (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-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 systems are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. Because of this our geared motors tend to be 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 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 components used and surface finish maximizes load capacity. This great gearing capacity enables smaller wheels to be utilized for the same torque, and smaller gears with outstanding power density can also increase reliability. Ever-Ability geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially decreased and therefore the equipment backlash to be minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard through parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
