Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless drive for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine interfaces, produces the Ever-Ability worm gearbox the default decision 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-Electrical power Worm gearboxes provide substantial torque with low swiftness gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial path. The gears in these gearboxes can 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. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Electricity gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear devices are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, making them much popular in the industry. Because of this 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 backed simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This huge gearing capacity enables smaller wheels to be utilized for the equal torque, and smaller sized gears with excellent power density can also increase reliability. Ever-Electrical power geared motors are consequently incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform necessary for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes plus Geared Motors
EP’s precision worm gearboxes are created for those more demanding applications where small proportions, high torque, high ratio, low backlash, low noises and long lifetime are required. Provided in 9 sizes, these worm gearboxes could be supplied with totally free insight shaft, with hollow bore insight shaft and electric motor flange, and double decrease combination units for slow rate applications. By using cast iron housings, top quality bronze alloy worm tires and long life bearings, reliability and efficiency are the crucial features of this range.
High Precision Right Angle Transmission
Long Lifetime
WIDE RANGE Of Ratios
Special Surface Treatments
