Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our success came from our relentless get for quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, would make the Ever-Electricity 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 a highly versatile drive system.
Ever-Electricity Worm gearboxes provide excessive torque with low swiftness gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be proper 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 (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electricity gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear units are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, producing them much sought after in the industry. Because of this our geared motors are often 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 style in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This substantial gearing capacity allows smaller tires to be utilized for the comparable torque, and smaller gears with excellent power density can also increase reliability. Ever-Ability geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to be minimized.
Dual 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
