Technical Field

[0001] The utility model relates to the technical field of automobile engine water pump shafts, in particular to an automobile engine water pump shaft which is easy to lubricate. Background Art

[0002] The water pump shaft of an automobile engine is an important component of the automobile engine cooling system, and it plays a key role in the water pump; the water pump shaft is generally made of forged steel, which has good wear resistance and fatigue strength, and can meet the needs of long-term operation of the water pump. The water pump shaft is supported on the water pump housing through bearings, with an impeller installed at one end and a drive pulley installed at the other end. The impeller rotates under the drive of the pump shaft, generating centrifugal force to push the coolant to flow, and the drive pulley is connected to the engine crankshaft to transmit power through a belt or chain; the water pump shaft is a key component to support the rotation of the impeller, and at the same time transmits the power of the engine crankshaft to the impeller, so that the impeller can rotate normally. Through the rotation of the water pump shaft, the impeller is driven to extract the coolant from the water tank, and then flows back to the water tank after passing through the engine cooling system, forming a cycle to ensure the normal operating temperature of the engine; in daily use, attention should be paid to the maintenance and care of the water pump shaft, and faults should be discovered and handled in a timely manner;

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0031] The present embodiment is a water pump shaft of an automobile engine which is easy to lubricate.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one end of the shaft rod 1 is fixedly connected with the upper shaft tooth 2, the other end of the shaft rod 1 is fixedly connected with the bottom shaft tooth 3, a clamping plate 4 is arranged on the outer side of the shaft rod 1, and a heat dissipation fin 5 is arranged on the outer side of the clamping plate 4, and the heat dissipation fin 5 is distributed in an array, a first connecting plate 6 is fixedly connected to the outer side of one end of the clamping plate 4, a first mounting hole 7 is opened inside the first connecting plate 6, a second connecting plate 8 is fixedly connected to the outer side of the other end of the clamping plate 4, and a second mounting hole 9 is opened inside the second connecting plate 8, the first mounting hole 7 and the second mounting hole 9 are both slidably connected with studs 10, the studs 10 are threadedly connected to the nut 11, and the lower side of the nut 11 is tightly fitted with the outer side of the second connecting plate 8.

[0033] like Figure 1 and Figure 5 As shown, an oil delivery column 12 is fixedly connected to the outer side of the shaft 1, and an oil delivery groove 13 is arranged on the inner side of the oil delivery column 12. The oil delivery grooves 13 are distributed in an array, and an oil storage groove 14 is opened inside the oil delivery column 12. The oil storage groove 14 is connected to the oil delivery groove 13. A connecting block 15 is arranged on the outer side of the oil delivery column 12, and the oil delivery column 12 is rotatably connected to the first baffle 16 and the second baffle 17 through the connecting block 15. Specific embodiment 2

[0035] This embodiment is to solve the problem of poor heat dissipation effect.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping sheet 4 can be bent. When the heat dissipation fins 5 are straightened, the heat dissipation fins 5 arrayed on the outside of the clamping sheet 4, the heat dissipation fins 5 and the outer ends of the heat dissipation fins 5 will become shorter. When the shaft 1 needs to dissipate heat, the clamping sheet 4 is opened to allow the clamping sheet 4 to be stuck on the outside of the shaft 1, and then the stud 10 is passed through the first mounting hole 7 and the second mounting hole 9, and the nut 11 is threadedly connected with the stud 10. Under the joint action of the stud 10 and the nut 11, the clamping sheet 4 is firmly fixed on the outside of the shaft 1, and the clamping sheet 4 will also rotate with the rotation of the shaft 1 without sliding. Since the clamping sheet 4 has good thermal conductivity, the heat generated by the shaft 1 will be transferred to the heat dissipation fins 5 through the clamping sheet 4. The heat dissipation fins 5 have a large contact area with the air, which can transfer the heat on the shaft 1 to the air, thereby preventing the shaft 1 from overheating and causing performance deterioration, thereby extending the service life.

[0037] It should be noted that, since the clamping piece 4 can be bent, the clamping piece 4 can also be applicable to shafts 1 with different diameters, and the stud 10 and the nut 11 can be fixed in the first mounting hole 7 and the second mounting hole 9 in the same way. Specific embodiment three

[0039] This embodiment is to solve the problem of inconvenient oil filling.

[0040] like Figure 1 and Figure 5 As shown, after long-term use, cracks will inevitably appear on the outer side of the shaft rod 1, and the outer side of the shaft rod 1 needs to be lubricated to extend its service life. When oiling is needed, open the first baffle 16 and the second baffle 17, and inject the oil from the oil bottle along the outer side of the shaft rod 1. The oil will flow along the shaft rod 1 into the oil storage tank 14, and then be discharged from the oil delivery tank 13. Since the oil delivery tank 13 is distributed in an array, the oil will flow evenly to the outer side of the shaft rod 1 to prevent the outer side of the shaft rod 1 from having uncoated areas. When the oiling is completed, close the first baffle 16 and the second baffle 17. In addition, the first baffle 16 and the second baffle 17 are magnetically connected, and there is a strong adsorption between the first baffle 16 and the second baffle 17, so it will not be accidentally opened. The closed first baffle 16 and the second baffle 17 can prevent external debris from accumulating in the oil storage tank 14 and the oil delivery tank 13, resulting in uneven oiling.
