Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low quickness gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite long in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear models are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making them much sought after in the industry. Because of this our geared motors tend to be to be found within our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported 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 materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be used for the same torque, and smaller gears with extraordinary power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
