Immediate coupling between servo electric motor and worm gear is among the important strengths of EP worm gearmotors, which combine DC engine technology with exceptional toughness and wear resistance. 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 business lead screw / ball screw adapted to our flexible modular concept.
Based on this we are able to select a wide variety of standard customizations to meet up the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special property such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our item range with more than 1000 different standard gearboxes is probably a good begin to have the ability to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric motor is integrated with the gearbox into a single device (the first gear is on the motor shaft). Individual gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our specialists will be pleased to help you make your selection. We will be happy to send you documentation or style a suitable set directly, on request.

Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable 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 market. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics 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 can 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. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear models are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. Consequently our geared motors are often to be found Compact Worm Gearbox 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 supported simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be used for the same torque, and smaller sized gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as regular in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
