The Experimental and Design Method Research on Interference Fit of Fabricated Single-Arm Planetary Carrier

To improve load capacity of fabricated single-arm planetary carrier, and enlarge its applied fields, the calculation criterion of load capacity of fabricated single-arm planetary carrier under given interference amount is described according to relevant calculation theories in this paper. Some experiments have been carried out to verify the influence of different interference amounts forced on load capacity, and also the variation of force is confirmed while the planet wheel axle is pressed into the body of planetary carrier with given interference amount. The theoretical basis and reference of fabricated single-arm planetary carrier is ultimately put forward and applied in some relevant engineering practice.
