Direct coupling between servo motor and worm gear is one of the crucial strengths of EP worm gearmotors, which combine DC motor technology with exceptional sturdiness and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Because of their reduced current attract, these gearmotors deliver more accurate control of working temperature and higher effectiveness.

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 can 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 real estate such as for example 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 combination of this kind of properties, our item range with more than 1000 different standard gearboxes is most likely a good begin to be able to deliver a product that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox into a single device (the first gear is on the engine shaft). Separate 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 inside our e-shop. Our experts will be happy to help you create your selection. We will be happy to send you documentation or style a suitable set directly, on ask for.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single 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, smoothly running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, making them much popular in the industry. Because of this our geared motors tend to be to be found as part of 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 guarantees optimum rolling contact 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 wheels to be used for the same torque, and smaller gears with remarkable power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary 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 gear technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
