Small bevel gear shaft support structure, why the left bearing diameter should be positioned on both sides?
On the shoulder on the same can play a role of limiting, to make the shaft rigidity as well as from the design angle of shoulder ladder plane is very small, small steps under axial force on gear not so good, so with the help of the bearing inner ring plane to ensure large gear axial bearing force.
Depending on the shape of the shaft, the shaft can be divided into two types: crankshaft and straight shaft.According to the bearing of the shaft, it can be divided into:Rotating shaft, when the work takes both the bending moment and the torque, it is the most common shaft in the machine, such as shafts in various reducers.The spindle is used to support the rotating parts, only to bear the bending moment, but not to transfer the torque. Some spindles rotate, such as the axle of the railway vehicle, etc. Some spindles do not rotate, such as the shafts of the supporting pulleys.The drive shaft is mainly used to transfer torque and bearing moment, such as the long axis, the automobile crane moving mechanism in the drive shaft.
Oil retaining ring directly on the shaft shoulder, can play a role of limiting, but from the angle of design to make the stiffness of shaft to shaft shoulder, ladder plane is very small, so small steps under the gear axial force can not achieve the best, so the bearing inner ring plane to ensure large gear axial bearing force.A gear shaft is a mechanical part that supports rotating parts and rotates together to convey motion, torque, or bending moment. Generally round metal rods, each segment may have different diameters. A revolving part of a machine is mounted on a shaft.
The small bevel gear shaft supporting structure, the left bearing inner diameter on both sides, because the left oil retaining ring is not axial positioning on the shaft work, while the small bevel gear over limit, to prevent the small bevel gear back (Xiang You), so as to ensure the stability of gear clearance.
