ABSTRACT

Shaft is composed of the main parts of the machine parts, all made rotary motion transmission parts (such as: gears, worm, etc.) must be installed on the transmission shaft to carry out the movement and force transmission, drive shaft commonly used in the transmission and drive axle the connection between. This axis generally longer, and high speed, can not bear to withstand torque moment. Should be sufficient to drive shaft stiffness and high critical speed, the drive shaft of the design method is based on mechanics of materials, according to the intensity calculated initially for the shaft diameter, determined according to the load they bear the heat treatment process, and then check the critical speed and torsion stability. In the strength calculation,
Given the large safety factor taken, so that shaft size is too large, the paper discusses the shaft design process, and in accordance with existing norms of surface treatment to add some way of example, the surface of flange.





Keywords￡oShaft, parts, stiffness, strength, surface flange
