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-artwork technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, would make the Ever-Vitality worm gearbox the default choice for the sector. 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-Vitality Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in design, these gears can perform 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 bigger) and its own body is generally quite lengthy in the axial path. The gears in these gearboxes could be suitable 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 (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Ability gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear systems are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. Consequently our geared motors tend to be to be found within 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 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 excessive gearing capacity enables smaller tires to be utilized for the equal torque, and smaller gears with remarkable power density also increase reliability. Ever-Ability geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing play necessary for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Dual 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 gear technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
