Ever-Power worm gearboxes have earned a status 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 will be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, would make the Ever-Electric power worm gearbox the default personal preference for the market. 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-Ability Worm gearboxes provide great torque with low quickness 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 qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes could be suitable or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Vitality gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear devices are built 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. Because of this 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This large gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Electricity geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing play 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 used as standard in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
