Selecting Fits for Inner Bearing Ring

Internal bearing ring tolerance field is selected as per GOST 52071. Since in the reduction gear the inner rings of bearings of all shafts are rotated and the outer rings are in place, local loading takes place, therefore we will have transitional fits .

For the inner bearing ring of the high-speed shaft, we take the size. For the outer bearing ring of the high-speed shaft, which is mounted in the gearbox housing, we take the size:.

For inner ring of low-speed shaft bearing we take size. For the outer ring of the low-speed shaft bearing, which is mounted in the gearbox housing, we take the size:.

For the inner bearing ring of the intermediate shaft we take the size. For the outer bearing ring of the intermediate shaft, which is mounted in the gearbox housing, take the size:.
