Abstract
The utility model discloses a driving bevel gear for a reducer casing. The driving bevel gear for the reducer casing comprises a rotating shaft. The left end of the rotating shaft is provided with a wheel flange. The conical face of the wheel flange is provided with cone teeth. Outer surfaces of the cone teeth are provided with hard alloy layers. The right end face of the rotating shaft is provided with a threaded hole. The outer wall of the rotating shaft is provided with a stair in a turning mode. The stair is equal to the threaded hole in length. Symmetric key grooves are formed between the stair and the cone teeth on the rotating shaft. The driving bevel gear for the reducer casing is simple in structure and convenient to connect due to the connected threaded hole formed in the right end face. Further, service life of the driving bevel gear for the reducer casing is prolonged through the function of the hard alloy layers.
Description
Technical field:
The utility model relates to the speed reducer part field, relates in particular to a kind of drive bevel gear for speed reducer.
Background technique:
Use the gear of a large amount of intermeshing transmissions in the speed reducer, comprising intermeshing drive bevel gear and driven wheel of differential.In drive bevel gear and the driven wheel of differential engagement driving process, its engagement position causes bevel gear to damage easily because long-term motion is worn easily, and working life is short.
