Special wishes possible
Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement originated from our relentless travel for quality with state-of-the-artwork technology, all and will be offering worm gearboxes happen to be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, would make the Ever-Vitality worm gearbox the default personal preference 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-Electric power Worm gearboxes provide huge torque with low rate gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its body is generally quite lengthy in the axial direction. The gears in these gearboxes can be ideal or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear units are designed to withstand the toughest commercial applications.
The apparatus 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 within 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style in mixture 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 remarkable power density also increase reliability. Ever-Ability geared motors are therefore incredible space savers.
Gearing produced 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.
Dual chamber shaft seals developed 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 equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
