Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement came from our relentless get for top quality with state-of-the-art technology, all while offering worm gearboxes happen to be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, creates the Ever-Vitality worm gearbox the default determination for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Electricity Worm gearboxes provide large torque with low acceleration 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 act like helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite long in the axial path. The gears in these gearboxes can be ideal or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Electrical power 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 designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. Because of this our geared motors tend to be to be found 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 backed by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This great gearing capacity enables smaller wheels to be used for the exact torque, and smaller gears with exceptional power density also increase reliability. Ever-Electricity geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as standard during parallel shaft, shaft mounted and helical worm gears for a high 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
Precision Worm Gearboxes and also Geared Motors

Offered in 9 sizes, these worm gearboxes could be supplied with totally free insight shaft, with hollow bore input shaft and motor flange, and double decrease mixture units for slow velocity applications. By using cast iron housings, high quality bronze alloy worm tires and extended life bearings, reliability and overall performance are the crucial top features of this range.
High Precision Right Angle Transmission
Long Lifetime
WIDE RANGE Of Ratios
Special Surface Treatments
