Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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 high torque with low swiftness gear ratio. Being simple and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix position is typically comparatively bigger) and its body is normally quite long in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear systems are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse mounting positions and applications, making them much popular in the industry. Consequently our geared motors are often 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 supported simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the materials 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 excellent power density also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as regular in parallel shaft, shaft mounted 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
