Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. 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 simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively larger) and its 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 option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems 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. As a result our geared motors tend to be to be found as part of 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 by FEM (Finite Element Method). This tooth geometry ensures 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 high gearing capacity allows smaller tires to be utilized for the same torque, and smaller sized gears with exceptional power density can also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the gear backlash to be minimized.
Double chamber shaft seals produced by Ever-Power are utilized as standard in parallel shaft, shaft mounted 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
