Helical Gearbox

The new helical gearbox ROBUS-A2 by motive completes the range of in-line gearboxes in an aluminium monolithic housing. The product gains its versatility by its modular design with detachable output flange and foot base that allows easy and quick conversion between foot and flange mounting. It is interchangeable with most other gearboxes brands. Flexible mounting is assured by IEC flange and hollow shaft. Choice of hollow input flanges permits direct mounting of any standard motor. The construction of the gearbox makes it possible to mount any size in any position. This flexibility is achieved by the use of high strength steels, with case hardening to 58 ±2 HRC that reduces the wear rate and increases the service factor and power capacity of gears. The surface of gears is exposed to a bombardment of micro-spheres that induces compression and increases further the fatigue resistance. All gears are profile ground to DIN 3962 class 6 accuracy for low noise and high efficiency. The shafts are made from tempered steel, thus increasing their capacity to withstand shearing stresses. If the mechanical robustness and the service factor of an helical gearbox are mainly influenced by the centres distance of the last stage, Robus-A confirms to be robust like the whole ROBUS series. Dual bearing support on the input shaft assures precise alignment of the first stage gears and reduces vibrations and consequent gear wear. The intermediate shaft is rigidly supported by 2 bearings on both ends, thus imparting greater flexural strength and reducing vibrations.
