Immediate coupling between servo motor and worm gear is among the important strengths of EP worm gearmotors, which combine DC engine technology with exceptional sturdiness and wear resistance. Electric motor and gearbox are designed as you single, compact unit. Because of their reduced current pull, these gearmotors deliver more accurate control of working 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 standard customizations to meet the requirements of varied properties that are essential 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 start to have the ability to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric engine is built-in with the gearbox into a single device (the first gear is directly on the motor shaft). Individual gearboxes for connection to 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 experts will be pleased to help you create your selection. We will be happy to send you documentation or style a suitable set directly, on request.

Special wishes possible
Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting choices, 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 reduction gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively larger) and its body is generally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice 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 are 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 gear housings are machined on all sides and permit diverse mounting positions and applications, producing them much sought after in the industry. Because of this 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 backed 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 high gearing capacity allows 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 therefore incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a high 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
