Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low speed 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 position is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), 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, smoothly running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, producing them much popular in the industry. Consequently 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 ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller wheels to be utilized for the same torque, and smaller gears with excellent power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become 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
Diverse mounting options
