Special wishes possible
Ever-Power worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our achievement came from our relentless travel for quality with state-of-the-art technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, creates 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Vitality Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in design, these gears can perform 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 bigger) and its body is normally quite long in the axial path. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one 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 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 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 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 large gearing capacity allows smaller tires to be utilized for the comparable torque, and smaller gears with excellent power density can also increase reliability. Ever-Electricity geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing perform necessary for troublefree rolling contact to be substantially reduced and therefore the gear backlash to become minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard on 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 programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
