Ever-Power worm gearboxes possess earned a popularity 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 happen to be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, creates the Ever-Ability worm gearbox the default decision for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide huge torque with low speed 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 larger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be best or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electricity gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting 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 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 guarantees optimum rolling contact under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller gears with outstanding power density also increase reliability. Ever-Electricity geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to become minimized.
Dual chamber shaft seals developed 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 equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
