Direct coupling between servo electric motor and worm gear is one of the important strengths of EP worm gearmotors, which combine DC engine technology with exceptional durability and wear resistance. Motor and gearbox were created as one single, compact unit. Thanks to their reduced current draw, these gearmotors deliver considerably more accurate control of working temperature and higher efficiency.

Ever-Power worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless get for level of quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, produces the Ever-Electrical power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide great torque with low velocity gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be best or left-handed depending upon the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Vitality gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly powerful drive systems.
Our high-performance gear models are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much sought after in the industry. Consequently our geared motors are often to be found as part of 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 supported simply 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 huge gearing capacity enables smaller wheels to be used for the exact torque, and smaller gears with excellent 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 reduced 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 high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
