Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power 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 act like helical gears, but its helix angle is typically comparatively larger) and its body is normally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear models are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse mounting 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling contact under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller sized gears with extraordinary 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 required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are utilized as regular 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
