Problems solved by technology

[0002] As there are more and more large-scale trucks, the demand for the axle main reducer is also increasing. The axle main reducer is the main part of the automobile transmission system to reduce the speed and increase the torque. Usually the axle main Composed of bevel gear and driven bevel gear, the driving bevel gear and driven bevel gear mesh with each other, and the rotation of the driving bevel gear drives the driven bevel gear to rotate to work, but the driven bevel gear often breaks first during work, and the driving gear The strength is still sufficient, but due to the early damage of the driven wheel, the driving wheel is also damaged, resulting in early failure of the gear pair and insufficient life.

Embodiment Construction

[0014] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0015] A bevel gear structure of a final reducer includes a driving bevel gear and a driven bevel gear that mesh with each other. The driving bevel gear includes a driving bevel gear large end 1, an end face 2 and a shaft 3, and is characterized in that: the driving bevel The diameter of the gear big end 1 is D1=230.5mm, the tooth thickness of the driving bevel gear big end 1 is M=58mm, the end surface 2 of the driving bevel gear and the shaft 3 are fixedly connected; the driven bevel gear, Including the driven bevel gear inner cone 10, the driven bevel gear inner end 4 and the driven bevel gear face cone 11. The diameter of the driven bevel gear is D2=302.79mm, and the thickness of the driven bevel gear is H=58.8mm . The materials of the driving bevel gear and the driven bevel gear are both 22CrMoH. The surface of the driving ...

Abstract

The invention discloses a novel bevel gear which comprises a driving bevel gear body and a driven bevel gear body engaged with the driving bevel gear body. The driving bevel gear body comprises a driving bevel gear body big end, an end face and a shaft. The novel bevel gear is characterized in that the diameter D1of the driving bevel gear body big end is 230.5mm, the thickness M of a tooth part of the driving bevel gear body big end is 58 mm, and the end face of the driving bevel gear body is fixedly connected with the shaft; and the driven bevel gear body comprises a driven bevel gear body inner cone, a driven bevel gear body big end face and a driven bevel gear body surface cone, the diameter D2 of the driven bevel gear body is 302.79 mm, and the thickness H of the drive bevel gear body is 58.8 mm.

Description

Technical field [0001] The invention relates to a gear, in particular to a new type of bevel gear. Background technique [0002] As there are more and more large trucks, the demand for the axle final reducer is also increasing. The axle final reducer is the main component of the automobile driveline to reduce the speed and increase the torque. Usually the axle final reducer includes the active The bevel gear and the driven bevel gear are composed of the driving bevel gear and the driven bevel gear meshing with each other. The rotation of the driving bevel gear drives the driven bevel gear to rotate and then it can work. However, the driven bevel gear often breaks first during work, and the driving gear The strength is still rich, but due to the early damage of the driven wheel, the driving wheel is also damaged, resulting in early failure of the gear pair and insufficient life. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the pres...
