Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engines, and more specifically, it relates to a new type of oil pump oil seal seat. Background Art
[0002] The oil seal seat is a bearing used on an automobile engine to seal and lock the crankshaft and camshaft, which has the function of preventing engine oil from leaking and keeping the inside of the engine clean. The oil seal seat plays an important role in the normal operation of the engine.
[0003] When the oil pump is in working condition, the oil pump camshaft rotates at a high speed, and the inner cavity is in a state of high temperature and high pressure. When the oil seal is severely worn or the internal pressure is too high, engine oil will leak from the deep part of the oil seal, resulting in oil leakage and other situations. The leaked engine oil seeps out from the oil seal seat, which will have a certain impact on the engine, thereby shortening the service life of the engine to a certain extent. At the same time, too much leaked engine oil will cause waste and increase costs. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a new type of oil pump oil seal seat aiming at the above deficiencies of the prior art, which can collect the engine oil leaked from the oil seal seat, save costs, and avoid the leaked engine oil from affecting the operation of the engine, effectively extending the service life of the engine.
[0005] The technical solution of the utility model is as follows: A new type of oil pump oil seal seat includes an oil seal seat body. An inner wall of the oil seal seat body is provided with a first mounting hole for mounting an oil seal. One side of the first mounting hole is provided with an inner sealing groove. An outer wall of the oil seal seat body at one end away from the inner sealing groove is provided with an outer sealing groove. Sealing rings are arranged on both the outer sealing groove and the inner sealing groove. One end of the oil seal seat body close to the inner sealing groove is provided with a second mounting hole. An oil drain joint is movably inserted into the second mounting hole. A return oil passage is arranged in the oil drain joint. The return oil passage includes a first branch and a second branch. The first branch and the second branch are perpendicular to each other and communicate with each other. The second branch runs horizontally through the oil drain joint.
[0006] As a further improvement, there are two outer sealing grooves and two inner sealing grooves.
[0007] Furthermore, the sealing ring is an O-ring.
[0008] Furthermore, a sinking groove is arranged on the inner wall of the oil seal seat body. The sinking groove is located between the first mounting hole and the inner sealing groove. One end of the first branch communicates with the bottom of the sinking groove.
[0009] Further, one end of the engine oil connector connected to the oil seal seat body is provided with a conical opening, the conical opening is communicated with one end of the first branch, and the central axis of the conical opening coincides with the central axis of the first branch.
[0010] Further, both sides of the engine oil connector are provided with grooves, and the bottom of the grooves is communicated with one end of the second branch.
[0011] Further, the bottom of the engine oil connector is provided with a threaded hole.
[0012] Beneficial effects

Specific embodiments
[0021] The following further describes the present utility model with reference to specific embodiments in the drawings.
[0022] Refer to Figures 1-5, a new type of oil pump oil seal seat, including an oil seal seat body 1. There is a first installation hole 2 on the inner wall of the oil seal seat body 1 for installing an oil seal 17. There is an inner seal groove 4 on one side of the first installation hole 2. There is an outer seal groove 3 on the outer wall of the oil seal seat body 1 at the end far from the inner seal groove 4. Sealing rings 5 are provided on both the outer seal groove 3 and the inner seal groove 4. One end of the oil seal seat body 1 close to the inner seal groove 4 is provided with a second installation hole 6. An oil pipe joint 7 is movably inserted into the second installation hole 6. There is a first seal groove 13 in the second installation hole 6, and a sealing ring is installed in the first seal groove 13 to further enhance the sealing performance between the oil pipe joint 7 and the oil seal seat body 1. There is an oil return passage in the oil pipe joint 7. The oil return passage includes a first branch 8 and a second branch 9. The first branch 8 is perpendicular to and communicates with the second branch 9, and the second branch 9 horizontally penetrates the oil pipe joint 7. By installing the oil pipe joint 7 on the oil seal seat body 1, the leaked oil is collected through the oil pipe joint 7, avoiding waste, saving the use cost, and avoiding the leaked oil from affecting the operation of the engine, effectively extending the service life of the engine.
[0023] In this embodiment, there are two outer seal grooves 3 and two inner seal grooves 4. Increasing the number of outer seal grooves 3 and inner seal grooves 4 on the oil seal seat body 1 further enhances the sealing performance of the oil seal seat body 1. In other embodiments, on the premise of not affecting the overall structural strength of the oil seal seat body 1, the number of outer seal grooves 3 and inner seal grooves 4 can be increased, such as three, four, etc.
[0024] In this embodiment, the sealing ring 5 is an O-ring. The O-ring is convenient to disassemble and assemble and has a good sealing effect, further enhancing the sealing performance of the oil seal seat body 1.
[0025] In this embodiment, there is a sink 10 on the inner wall of the oil seal seat body 1. The sink 10 is located between the first installation hole 2 and the inner seal groove 4. One end of the first branch 8 communicates with the bottom of the sink 10, and the other end of the first branch 8 communicates with the second branch 9. When oil leaks in the oil seal seat body 1, the leaked oil flows along the inner wall of the oil seal seat body 1 into the sink 10, facilitating the leaked oil to flow out along the first branch 8 and the second branch 9. There are inclined surfaces 16 on both sides of the end of the sink 10 far from the oil pipe joint 7, which is beneficial for the leaked oil to flow into the sink 10.
[0026] In this embodiment, one end of the oil pipe joint 7 connected to the oil seal seat body 1 is provided with a tapered opening 14. The tapered opening 14 communicates with one end of the first branch 8, and the central axis of the tapered opening 14 coincides with the central axis of the first branch 14. The bottom of the tapered opening 14 communicates with one end of the first branch 8, which can prevent the leaked oil from not flowing out along the first branch 8 in time and accumulating in the sink 10, affecting the internal cleanliness of the oil seal seat body 1 and thus affecting the sealing of the oil seal seat body 1.
[0027] In this embodiment, grooves 11 are provided on both sides of the oil connector 7. The bottom of the groove 11 communicates with one end of the second branch 9. Internal threads are provided in the groove 11, and other components are threadedly connected to the oil connector 7 through the internal threads in the groove 11. During installation, thread sealant can be used to further enhance the sealing performance with the oil connector 7 to avoid oil leakage.
[0028] In this embodiment, a threaded hole 12 is provided at the bottom of the oil connector 7. The oil connector 7 is threadedly connected to the oil seal seat body 1. The detachable connection method is convenient for cleaning or replacing the oil connector 7. Since the installation position of the oil connector 7 is the stepped surface at one end of the oil seal seat body 1, it is not conducive to directly using tools such as wrenches to install the oil connector 7 on the oil seal seat body 1. When installing the oil connector 7, the bolt can be first threadedly connected to the threaded hole 12, and the bolt is tightened to the bottom of the threaded hole 12, and then the bolt is continuously rotated to achieve the purpose of installing the oil connector 7 on the oil seal seat body 1; in other embodiments, other connection methods can be used to install the oil connector 7 on the oil seal seat body 1, such as welding.
[0029] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicality of the patent.
