Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement came from our relentless get for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, would make the Ever-Ability 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-Ability Worm gearboxes provide great torque with low quickness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite long in the axial direction. The gears in these gearboxes could be correct 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 (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electric power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear products are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, producing them much popular in the industry. Consequently 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 backed simply 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 materials used and surface finish maximizes load capacity. This large gearing capacity allows smaller tires to be used for the exact torque, and smaller sized gears with extraordinary power density also increase reliability. Ever-Electricity geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are utilized as standard in 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 programs:
Excellent power density
Diverse mounting options
