Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] As shown in the figure, this hollow shaft fork spline pair mainly includes a spline shaft fork 1 and an inner spline spline sleeve 2. The spline shaft fork 1 is composed of a welding fork 3 and an outer spline spline sleeve 4. The fork 3 and the outer spline spline sleeve 4 are welded into an integral structure. The inner spline spline sleeve 2 is set on the outside of the outer spline spline sleeve 4, and the inner spline spline sleeve 2 and the outer spline sleeve 4 cooperate with each other. The outer spline spline sleeve 4 is a hollow structure. The inner spline spline sleeve 2 is covered with a sealing device 5, and the sealing device 5 and the spline shaft fork 1 are welded and fixed to isolate external impurities and dust.

[0015] The present invention adopts welding fork 3 and outer spline spline sleeve 4 to be welded together, and welding f...

Abstract

The invention relates to a spline pair of a hollow shaft fork. The spline pair mainly comprises a spline shaft fork and an internal splined sleeve, wherein the spline shaft fork consists of a welding fork and an external splined sleeve; the internal splined sleeve is sleeved outside the external splined sleeve and matched with the external splined sleeve; and the external splined sleeve has a hollow structure. The spline pair has the advantages that: the weight for the raw materials of the spline fork can be reduced by 37.7 percent; and after a mathematical model is established to perform static stress analysis by using CAE software, the stress is only increased by about 5 percent while the weight of the hollow spline shaft is reduced by 37.7 percent. The fact shows that the strength of the hollow spline shaft fork is substantially the same as that of a solid spline shaft fork while the weight is greatly reduced, namely the hollow spline shaft fork has higher comprehensive performance; and meanwhile, the structure ensures higher working performance for the spline pair.

Description

technical field [0001] The invention mainly relates to the field of spline pairs, and mainly relates to a hollow shaft fork spline pair. Background technique [0002] At home and abroad, the heavy-duty sliding spline pair is generally composed of a spline shaft fork (outer spline) and a spline sleeve (inner spline). The spline shaft fork is a solid structure, and the material is generally made of For solid round steel, the processing technology is generally blanking-forging-shot blasting-quenching and tempering-rough and fine turning-milling splines-quenching, etc. The spline shaft fork material utilization rate of this design and processing is 59%, and there are forging, tempering and quenching heat treatment and multi-pass turning processing technology and external spline milling technology, more energy consumption and chips, processing cost and material cost higher. Contents of the invention [0003] The present invention solves the above-mentioned shortcomings of the...
