Description

technical field

[0001] The invention relates to a drive axle structure of a loader, in particular to a heavy-duty drive axle of a 5-ton loader. Background technique

[0002] The domestic construction machinery industry has begun to pay more and more attention to quality. The quality of the driving axle of the mainstream 5-ton loader in the industry can no longer meet the needs of customers, especially when it is operating under heavy load conditions. At present, the wheel gear parameters of the mainstream 5-ton loader drive axle generally adopt modulus 6.5, center distance 107.25, pressure angle 20°, addendum height coefficient 0.8, crown coefficient 0.3, tooth width 60, sun gear teeth number 15, planetary gear The number of teeth is 18, the number of teeth of the inner ring gear is 51, the number of planetary gears is 3, and the gears are not displaced; the wheel side bearings generally adopt 32221 bearings; the parameters of the differential generally adopt the bevel gear ...
