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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based upon this we are able to select a wide selection 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 residence such as small dimensions or low weight with regards to vitality, high efficiency, quiet and vibration-free operation, extended 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 an excellent start to be able to deliver something that stands out on your side.
Small gearboxes are high-level of quality gearboxes for regular drives. The electric electric motor is integrated with the gearbox into a single unit (the first gear 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 cannot be purchased in our e-shop. Our specialists will be pleased to help you create your selection. We are pleased to send out you documentation or style the right set directly, on demand.

Ever-Power worm gearboxes have earned a reputation to be a business benchmark worldwide. Our achievement came from our relentless get for quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, produces the Ever-Electricity worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Electrical power Worm gearboxes provide excessive torque with low swiftness 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 qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial path. The gears in these gearboxes could be ideal or left-handed dependant on the purpose.
Mounting choice include universal housing, part 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-Electricity gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear units are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much popular in the industry. Consequently 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This substantial gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Vitality geared motors are therefore 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 equipment backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are used as standard through parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
