Description

Technical Field

[0001] The utility model relates to the technical field of oil pumps, in particular to an oil pump with a shock-absorbing and noise-reducing structure. Background Art

[0002] The oil pump is an important component in the automobile lubrication system. Its main function is to increase the oil to a certain pressure and force it to the moving surfaces of various engine parts to form an oil film, providing a reliable working environment for the pressure components. The structural forms of oil pumps are mainly gear type and rotor type. Since nylon has the characteristics of non-toxicity, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, it is widely used to replace copper and other metals in the manufacture of bearings, gears, pump blades and other parts in machinery, chemical industry, instrumentation, automobile and other industries. Some gear-type oil pumps use nylon gears.

[0003] Traditionally, the oil pump will produce certain vibrations during use, and at the same time, the oil pump will make a lot of noise. Since the vibration and noise on the oil pump are unavoidable, the noise accompanied by vibration during the use of the oil pump will have a greater impact on the working environment.

[0004] Therefore, it is necessary to provide a new oil pump with a vibration reduction and noise reduction structure to solve the above technical problems. Utility Model Content

The filter plate 14 is fixedly installed between the two strip blocks 12, and the filter plate 14 is adapted to the corresponding rectangular holes 11, and the filter plate 14 can completely cover the corresponding rectangular holes 11.

[0022] In order to facilitate the rapid replacement of the shock-absorbing pad 2 and to facilitate the removal of the oil pump 3 from the mounting base 1, two movable grooves 15 are provided on the top of the mounting base 1, and transverse rods 16 are slidably installed in the two movable grooves 15. Springs 17 are sleeved on the two transverse rods 16, and the two ends of the two springs 17 are respectively in contact with the two adjustment blocks 18 and the inner wall of one side of the two movable grooves 15. The ends of the two transverse rods 16 that are close to each other are fixedly installed with adjustment blocks 18, and the two adjustment blocks 18 are both L-shaped. A clamping block 19 is fixedly installed on the side where the two adjustment blocks 18 are close to each other, and the two clamping blocks 19 are both U-shaped.

The two sliding blocks 6 are slidably installed in the four side grooves respectively.

[0024] In order to provide sliding space for the two transverse rods 16 and make the two blocks 19 slide more smoothly, the two movable grooves 15 are provided with a receiving groove on the side away from each other, and the two transverse rods 16 are slidably installed in the two receiving grooves. The bottom of the two blocks 19 are inlaid with multiple rolling balls.

[0026] The working principle of the oil pump with a vibration reduction and noise reduction structure provided by the utility model is as follows:

[0027] In the utility model, when the oil pump 3 needs to be used, the threaded rod 5 is rotated. Under the influence of the threads at both ends and the limiting effect of the two round rods, the two sliding blocks 6 will slide on the threaded rod 5 at the same time. The two sliding blocks 6 will drive the two connecting blocks 7 at the same time, and the two connecting blocks 7 will drive the two hollow protective covers 8. The two hollow protective covers 8 that were originally fitted together will gradually move away from each other until the two sliding blocks 6 contact the side of the two fixed blocks 4 that are close to each other, and the rotation of the threaded rod 5 can be stopped. At this time, a larger space will be exposed between the two hollow protective covers 8, and the top of the mounting seat 1 will be exposed.

[0028] Then, pull the vertical rod upward again, and the bottom end of the vertical rod will slide out of the corresponding recessed groove, and then push the adjustment block 18 to slide through the vertical rod, and the adjustment block 18 will drive the transverse rod 16 and the card block 19 to move together, and the transverse rod 16 will gradually slide into the receiving groove. After the adjustment block 18 slides to the predetermined position, one end of the transverse rod 16 will contact the inner wall of one side of the receiving groove. At this time, the adjustment block 18 has been adjusted to the predetermined position, and then push the vertical rod downward again to clip the bottom end of the vertical rod into another recessed groove, thereby determining the position of the adjustment block 18. After adjusting the position of a card block 19 , and then adjust the other block 19 in the same way, lay the shock-absorbing pad 2 on the top of the mounting seat 1, place the oil pump 3 on the top of the shock-absorbing pad 2, so that the oil pump 3 is located between the two blocks 19, and then adjust the two blocks 19 again to make the two blocks 19 contact with the mounting seat of the oil pump 3 again, so that the oil pump 3 can be fixed, and then rotate the threaded rod 5 in the opposite direction to reclose the two hollow protective covers 8, and then rotate and remove the two sealing covers, pour the coolant into the two hollow protective covers 8 through the two sealing covers, and then the oil pump 3 can be used normally.

[0029] Compared with the related art, the oil pump with a vibration reduction and noise reduction structure provided by the utility model has the following beneficial effects:

[0030] In the utility model, the oil pump 3 is temporarily fixed on the mounting base 1 by the cooperation of two clamping blocks 19, which can not only quickly complete the fixing of the oil pump 3, but also facilitate and quickly replace the shock-absorbing pad 2. The two hollow protective covers 8 constitute a relatively closed space, in which the oil pump 3 is placed to reduce the diffusion of noise and vibration. The two hollow protective covers 8 are filled with coolant in order to better isolate the noise with the help of liquid. At the same time, the coolant can play a role of heat exchange in the space inside the two hollow protective covers 8, which is convenient for the oil pump 3 to dissipate heat. The four rectangular holes 11 are the main heat dissipation through holes of the oil pump 1. There is a predetermined spacing between the two filter plates 14 and the four rectangular holes 11. Through this spacing, various connecting lines on the oil pump 3 can pass through conveniently. By rotating the threaded rod 5, the position of the two hollow protective covers 8 can be flexibly adjusted, which is convenient for the oil pump 3 to be placed in the two hollow protective covers 8, which can achieve a better noise reduction effect to a certain extent.
