Direct coupling between servo motor and worm gear is among the crucial strengths of EP worm gearmotors, which merge DC motor technology with exceptional toughness and wear resistance. Electric motor and gearbox were created as you single, compact unit. Because of their reduced current pull, these gearmotors deliver even more accurate control of operating temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with as well as without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based upon this we are able to select a wide variety of normal customizations to meet up the requirements of varied properties that are important for each application.
If your application takes a gearbox with some special property such as for example small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, force or temperature, integrated linear screw, or a mixture of such properties, our product range with more than 1000 different standard gearboxes is most likely an excellent start to be able to deliver a product that stands out on your side.
Small gearboxes are high-top quality gearboxes for regular drives. The electric motor is included with the gearbox right into a single device (the first equipment is on the engine shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our experts will be pleased to help you create your selection. We will be pleased to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement originated from our relentless travel for top quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, produces the Ever-Power worm gearbox the default determination for the sector. 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-Electric power Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes can be ideal or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key components for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear products are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse installation positions and applications, making them much popular in the industry. Consequently our geared motors are often to be found as part of 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 supported by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This great gearing capacity enables smaller tires to be utilized for the same torque, and smaller sized gears with exceptional power density can also increase reliability. Ever-Vitality geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play required for troublefree rolling contact to be substantially decreased and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard in 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 systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
