Ever-Power worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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-Power Worm gearboxes provide high torque with low velocity gear ratio. Being simple 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 angle is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be right 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 (solitary or dual), 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, efficiently running and highly dynamic drive systems.
Our high-performance gear models are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be used for the same torque, and smaller gears with remarkable power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling contact to be substantially reduced and then the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are used as regular in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
