Static strength of the teeth of powder metallurgy planetary pinions for the Zhiguli automobile differential

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The character of failure of a differential planetary pinion tooth was established. The crack originates on the side of the tooth under tension in the zone of contact of the involute surface with the surface of the base of the tooth and propagates in the direction of the radius of the root from the point of contact of these surfaces.

Comparative static fracture strength tests of the planetary pinions of a Zhiguli automobile produced from metal powder by hot pressing and standard production in 50th Anniversary of the USSR Volga Automobile Plant provided practically the same results. It may be assumed that the properties will be similar in other forms of tests, including production ones.
