Description

High-strength combined gear shaft Technical Field The utility model belongs to the technical field of gear shafts, and particularly relates to a high-strength combined gear shaft. Background The gear shaft is a core component of an integrated design of a gear and a shaft in a mechanical transmission system, and has the functions of transmitting power, changing rotating speed/torque and adjusting movement direction. The essence of the method is that gears (such as straight gears, helical gears, bevel gears and the like) and supporting shafts are manufactured into single parts or detachable split structures through forging, casting or machining processes, and the method is widely applied to the fields of automobiles, machine tools, aerospace and the like. The utility model discloses a high-strength combined gear shaft, which comprises a gear, wherein two sides of the gear are provided with a detachable combined gear shaft, the gear shaft comprises a first gear shaft part and a second gear shaft part, one side, close to the gear, of the first gear shaft part and the second gear shaft part is provided with a clamping assembly, the clamping assembly comprises at least two clamping blocks rotating in the gear shaft, a torsion spring is arranged on a rotating shaft of the clamping blocks, the periphery side of the clamping blocks is sleeved with a hoop ring, the inner wall of the gear is symmetrically provided with a first clamping ring and a second clamping ring, the gear and the gear shaft can be clamped through the clamping blocks abutting the first clamping ring, the gear shaft can be directly inserted into the gear, the gear shaft is locked through a blocking ring, the blocking ring is loosened, the gear shaft is pushed and pulled first, the gear shaft can be removed without interference fit, and damage to the gear and the shaft is caused.
