In the driving-shaft assembly of above-mentioned diesel engine, described barrier structure comprises the lining that is set on the oil pump drive end and the nut that is set on the oil pump drive end, described lining is resisted against on the inner ring of above-mentioned deep groove ball bearing, and described nut is resisted against on the lining and described nut is threaded connection on above-mentioned oil pump drive end.
In the driving-shaft assembly of above-mentioned diesel engine, be provided with compact heap between described body and the tapered roller bearing, an end of described compact heap is resisted against on the inner ring of tapered roller bearing, and the other end is resisted against the end of body.
In the driving-shaft assembly of above-mentioned diesel engine, the joint of described air compressor drive end and body is provided with chamfering, and above-mentioned compact heap and this chamfering are complementary.
In the driving-shaft assembly of above-mentioned diesel engine, the radius of described chamfering is 1-5mm.
In the driving-shaft assembly of above-mentioned diesel engine, the radius of described chamfering is 3mm.
In the driving-shaft assembly of above-mentioned diesel engine, described deep groove ball bearing is two.
Compared with prior art, the driving-shaft assembly of this diesel engine has the following advantages:
Adopted the diesel engine driving-shaft assembly of said structure, by air compressor drive end place on transmission shaft chamfering is set, reduced the stress at this place, be convenient to add the withdrawing in man-hour, solved transmission shaft because fatigue failure causes the problem of drive shafts fracture, made things convenient for the use of diesel engine, and improved the reliability of motor, cooperate with chamfering by compact heap, guaranteed the versatility of Product Assembly.
