Ever-Power worm gearboxes have earned a status to be a business benchmark worldwide. Our success originated 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 wide choice of mounting options, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. 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 basic and compact in style, 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 position is typically comparatively larger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary 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, efficiently running and highly powerful drive systems.
Our high-performance gear models are built 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. Because of this our geared motors tend to be 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 backed simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with 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 enables smaller wheels to be utilized for the same torque, and smaller sized gears with outstanding power density can also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to end up being minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as standard in parallel shaft, shaft mounted and helical worm gears for a high 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
