Description
Technical field
The utility model relates to a kind of gear pair, particularly relates to a kind of forklift gear-box spiral bevel gear pair.
Background technique
Spiral bevel gear pair is very important gear mesh in loader ransaxle, is also one of component being easy in ransaxle break down.Cause the intensity of gear pair too low, particularly propons gear pair is due to stressed larger, and rate of fault is higher, and contact ratio is too low, and transmission is not steady, and noise is large.Chinese patent ZL200820121523.1 discloses a kind of gear pair of loader drive axle, and it mainly comprises drive bevel gear and driven wheel of differential, and its material is single ordinary gear steel, does not consider the rotating speed of driving and driven bevel gear, wearing and tearing difference; Tooth profile parameter design is also unreasonable, and circular thickness is partially thin, have impact on working strength and bearing capacity, contact (area) pattern is along tooth depth direction only 40% ~ 70%, be 35% ~ 65% along tooth length direction, have impact on meshing quality and the work smoothness of gear pair, the usage requirement of energy-conservation loader can not be met.
Model utility content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact structure, and tooth profile parameter is rationally advanced, and meshing quality is high, a kind of forklift gear-box spiral bevel gear pair of usability excellence.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of forklift gear-box spiral bevel gear pair, comprise spiral bevel driving gear axle and bevel driven axle, the right-hand end of described spiral bevel driving gear axle is provided with spiral bevel driving gear, the left-hand end of described bevel driven axle is provided with the bevel driven be meshed with spiral bevel driving gear, described spiral bevel driving gear and the helix angle of bevel driven are respectively 35 degree, described spiral bevel driving gear and the pressure angle of bevel driven are respectively 22.5 degree, described spiral bevel driving gear and the surface of bevel driven are respectively equipped with hardened layer, the degree of depth of described hardened layer is 0.8-1.2mm.
As preferably, the material of described spiral bevel driving gear axle is 20CrMnTiH5, and the material of described bevel driven axle is 20CrMnTiH3.
The surface hardness of spiral bevel driving gear and bevel driven is respectively 58-64HRC, modulus 7.
After the parameter optimizations such as the modulus of gear pair, helix angle, pressure angle, effective case depth and surface hardness, improve intensity and the bearing capacity of gear pair, add safety coefficient and the contact ratio of gear pair, transferring power is steady, and rate of fault reduces.
Therefore, a kind of forklift gear-box spiral bevel gear pair of the present utility model, compact structure, rationally, tooth profile parameter optimization, meshing quality is excellent, and reliability is high, can meet the usage requirement of energy-conservation loader, has good social economic benefit in material collocation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
