Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm version, 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 speed gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its body is normally quite long in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear products are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much popular in the industry. As a result our geared motors are often 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 style 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 used for the same torque, and smaller gears with exceptional power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing enjoy necessary for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to be minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power\u2019s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
