Ever-Power worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our success came from our relentless get for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Electrical power worm gearbox the default decision for the industry. 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-Power Worm gearboxes provide excessive torque with low swiftness 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 bigger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes could be ideal or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. Consequently our geared motors are often 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 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 great gearing capacity enables smaller tires to be utilized for the exact torque, and smaller gears with extraordinary power density also increase reliability. Ever-Electrical 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 get in touch with to be substantially reduced and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are used as standard 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
