Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless travel for top quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, will make the Ever-Vitality worm gearbox the default personal preference for the market. 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-Electrical power Worm gearboxes provide huge torque with low speed gear ratio. Being simple and compact in design, 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 generally quite long in the axial path. The gears in these gearboxes can be proper or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Electricity gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, producing them much sought after in the industry. As a result our geared motors tend to be 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 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 substantial gearing capacity allows smaller wheels to be utilized for the comparable torque, and smaller sized gears with remarkable power density can also increase reliability. Ever-Electricity geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to become minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard for parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive programs:
Excellent power density
Diverse mounting options
Precision Worm Gearboxes and also Geared Motors
