The new PowerGear range of spiral bevel gearboxes combines the best features of the old Universal and Power Gear ranges, each produced to meet with a specific torque/speed spectrum.
The new PowerGear range of spiral bevel gearboxes combines the best features of the old Universal and Power Gear ranges, each produced to meet with a specific torque/speed spectrum.
The advantages of this approach are: the compact and rigid design assures highest performance at small dimensions and low weight; lubricated for life, the gearboxes are, depending on their size, maintenance-free, if operated under normal conditions; the high efficiency of the gearbox, 98%, saves energy costs; housing/flanges made of spheroidal graphite iron for maximum rigidity; fretting-free torque transfer using a friction-locked fit between shaft and gear; high quality taper roller bearings taking axial and radial loads and guaranteeing long operational life; Gleason cut gears for high torque ratings; and optimised gear tooth contact pattern during assembly leading to uniform load distribution.
The units are available in eight sizes, with six standard ratios from 1:1 to 5:1.
Shaft arrangements include two-, three- and four-way, and are available with solid shafts and hollow output shafts.
The units are also available with motor input flanges allowing many standard IEC framed motors to be fitted.
Torque range from 25 to 5200Nm with input speeds up to 6500rev/min.
For ease of installation the units have been designed, with universal mounting, allowing the units to be mounted from all sides.
Additional accessories include: a shrink disc - with hollow shaft extension for friction locked connections; keyless shafts - for attachment via clamping connections; minimum backlash - for greater accuracy than already offered as standard; and cooling packs - gearboxes fitted with aluminium cooling fins, with or without the addition of an axial fan to provide increased heat dissipation from the unit.
The main advantages of the PowerGear design will be found in applications with requirements of high torque at medium to high speeds, robust unit in a small size, useable in any mounting/working position.
Typical applications for the PowerGear are angular torque transfer and torque distribution in single, or multiple shaft configuration.
In nonstationary applications where weight is extremely important, the PowerGear design is the ideal solution.
For applications requiring a 1:1 ratio unit capable of handling greater torque than the standard PowerGear a higher rated "X-range" is available utilising the same size cases.
