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

Special wishes possible
Ever-Power worm gearboxes have earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless travel for level of quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice 
of mounting options, shaft configurations and motor interfaces, will make the Ever-Electrical power worm gearbox the default choice for the sector. 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-Electrical power Worm gearboxes provide substantial torque with low speed gear ratio. Being simple and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively larger) and its own body is generally quite long in the axial direction. The gears in these gearboxes can be right or left-handed depending upon the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, producing them much popular 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 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 exact torque, and smaller gears with extraordinary power density also increase reliability. Ever-Vitality geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard during parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
