Direct coupling between servo engine and worm gear is among the crucial strengths of EP worm gearmotors, which merge DC motor technology with exceptional durability and wear resistance. Electric motor and gearbox were created as one single, compact unit. Because of their reduced current pull, these gearmotors deliver more accurate control of working temperature and higher effectiveness.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement came from our relentless travel for quality with state-of-the-artwork technology, all and will be offering worm gearboxes happen to be affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, would make the Ever-Power worm gearbox the default personal preference for the industry. 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-Electricity Worm gearboxes provide high torque with low acceleration gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix position is typically comparatively larger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Ability gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly powerful drive systems.
Our high-performance gear models are designed to withstand the toughest industrial applications.
The gear 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 are often 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 backed by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with 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 large gearing capacity allows smaller wheels to be used for the comparable torque, and smaller gears with extraordinary power density can also increase reliability. Ever-Ability geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing enjoy necessary for troublefree rolling contact to be substantially decreased and therefore the gear backlash to become minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard through parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive devices:
Excellent power density
Diverse mounting options
