Ever-Power worm gearboxes possess earned a popularity 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 are inexpensive prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, 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 swiftness gear ratio. Being basic and compact in style, these gears can achieve 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 lengthy in the axial path. The gears in these gearboxes can be correct or left-handed dependant on 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-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse installation positions and applications, making them much popular in the industry. As a result 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact 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 high gearing capacity enables smaller wheels to be utilized for the same torque, and smaller gears with excellent power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy Compact Worm Gearbox allows the gearing enjoy necessary for troublefree rolling get in touch with to be substantially decreased and then 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 higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Diverse mounting options
