Abstract
The utility model discloses an assembly of diesel transmission shaft comprising the transmission shaft, bearings installed on the fuel pump driving end of the transmission shaft and bearings installed on the air compressor driving end of the transmission shaft; wherein the air compressor driving end of the transmission shaft is arranged with circular beads on the joint with the bearings and the circular beads are arranged pressing blocks engaged with the circular beads on the joint with the bearings. The utility model not only solves the problem of fracture of the diesel transmission shaft due to fatigue failure and is convenient for the employment of the diesel, but also improves the reliability of the diesel largely with little alter.
Description
Technical field
The utility model relates to the technical field on the diesel engine, especially relates to the diesel engine driving-shaft assembly that drives the oil pump running on a kind of diesel engine.
Background technique
When the diesel engine proper functioning turns round, be its fuel feeding at present, and its oil supply system is to be turned round to carry out fuel feeding by the oil pump that the transmission shaft on the diesel engine drives in the oil supply system by its oil supply system.Because transmission shaft its load when driving oil pump is bigger, and change very frequent, and because the structural characteristics of transmission shaft itself: promptly transmission shaft is when being provided with, the modes that adopt the shaft shoulder on bearing and the transmission shaft to cooperate more, and between the shaft shoulder on bearing fixing place and the transmission shaft because of the existence of its chamfering, its stress ratio is bigger, causes fatigue failure easily and then causes drive shafts fracture, has a strong impact on diesel engine and uses.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of diesel engine driving-shaft assembly, and it can effectively solve transmission shaft because of fatigue failure causes the problem of drive shafts fracture, has made things convenient for the use of diesel engine, and improves the reliability of motor.
For solving the problems of the technologies described above, the technical solution of the utility model is: the diesel engine driving-shaft assembly, comprise transmission shaft, be installed in the bearing of oil pump drive end on the transmission shaft and be installed in the bearing of air compressor drive end on the transmission shaft, the axis body of air compressor drive end and bearing cooperation place are provided with rounding on the described transmission shaft, are provided with the compact heap that matches with rounding between described rounding and the bearing.
As a kind of optimal way, described rounding is that radius is the rounding of 3mm.
Adopt the diesel engine driving-shaft assembly of said structure, be provided with rounding by oil pump drive end on transmission shaft, reduced the stress at this place, solved transmission shaft causes drive shafts fracture because of fatigue failure problem, make things convenient for the use of diesel engine, and improved the reliability of motor; And match the versatility that has kept product to assemble with rounding by increasing compact heap.Adopting radius is the rounding of 3mm, not only changes for a short time, and effect is big.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Accompanying drawing is the structural representation of diesel engine driving-shaft assembly of the present utility model.
Embodiment
With reference to accompanying drawing, a kind of diesel engine driving-shaft assembly of the present utility model is: comprise transmission shaft 1, be located at the bearing 3 that oil pump on the transmission shaft 1 drives the bearing 5 of an end and is installed in air compressor drive end on the transmission shaft 1, can adopt by being arranged on lining 4 that oil pump drives an end transmission shaft 1 and bearing 5 are held out against to fix again to strengthen closely cooperating between them; The axis body of air compressor drive end and bearing 3 cooperation places are provided with rounding on transmission shaft 1, and are provided with the compact heap 2 that matches with rounding between rounding and bearing 3, have kept the versatility of product assembling; And in order further to strengthen the transmission shaft torque resistant, can adopt radius is the rounding of 3mm, not only changes for a short time, and effect is big and when making this transmission shaft 1, can its quenching scope be strengthened, and also further improve the reliability of transmission shaft.
Claims (2)
1, diesel engine driving-shaft assembly, comprise transmission shaft (1), be installed in the bearing (5) of the last oil pump drive end of transmission shaft (1) and be installed in the bearing (3) that transmission shaft (1) is gone up the air compressor drive end, it is characterized in that: axis body and bearing (3) cooperation place that described transmission shaft (1) is gone up the air compressor drive end are provided with rounding, are provided with the compact heap (2) that matches with rounding between described rounding and the bearing (3).
2, diesel engine driving-shaft assembly according to claim 1 is characterized in that: described rounding is that radius is the rounding of 3mm.
