The included angle between the working shafts of the common constant velocity universal joint is generally smaller, and the defects of low working efficiency, poor reliability, poor stability, complex structure, large volume and the like exist.
In order to improve the included angle between the working shafts of the universal joint, a large number of duplex constant-speed universal joints are provided domestically to increase the included angle between the working shafts. However, as the service life of the duplex constant velocity universal joint increases, the problem of instability of the universal joint due to unidirectional increase or decrease of an included angle between working shafts can occur due to the problems of bearing abrasion and the like.
In view of the above problems, it is desirable to provide a high-stability cross shaft mechanism, which satisfies the requirement of the technical development of the high-stability duplex cross shaft.
