Variable-radius bearing set device

The invention relates to a combined bearing device, and specifically relates to a variable-radius bearing set device. The device is characterized by comprising a main bearing body A and a secondary bearing body B. the device is characterized in that the main bearing body is in shape of regular triangle; the secondary bearing body is in shape of inverted triangle; the main bearing body and the secondary bearing body form an isosceles right triangle; the main bearing body comprises an inclined surface and a bottom horizontal surface; the secondary bearing body comprises a triangle body and a base. The device is simple in structure, low in cost, convenient to operate and use, accurate, safe and reliable; and the device is energy-based. With the adoption of the device, the mechanism energy consumption can be decreased by about 80%. The device is applicable to generators, electric vehicles, automobiles, steamers, agricultural machines and lathes, so that the application field is wide. 本发明涉及组合轴承装置，具体为种可变半径轴承组装置。其特点
