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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or 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 regular customizations to meet the requirements of various properties that are important for each application.
If your application takes a gearbox with some special property or home such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with an increase of than 1000 different standard gearboxes is probably a good begin to have the ability to deliver a product that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox right into a single unit (the first equipment is directly on the motor shaft). Individual 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 will be happy to send you documentation or design a suitable set directly, on ask for.

Special wishes possible
Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), 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 dynamic drive systems.
Our high-performance gear systems are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, producing them much sought after in the industry. As a result our geared motors tend to be 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 ensures 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 high gearing capacity enables smaller tires to be utilized for the same torque, and smaller sized gears with extraordinary power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft installed 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
