Description

Technical Field

[0001] This utility model relates to the field of cam bearing cover technology, and more specifically to a cam bearing cover with a long service life. Background Technology

[0002] A cam is a component with a curved profile or groove, and it is the core component of a cam mechanism. Cams typically rotate continuously at a constant speed or reciprocate linearly, pushing a follower through their curved profile or groove, causing the follower to reciprocate or oscillate according to a predetermined pattern. During operation, the cam needs to rotate around its axis. The cam bearing housing and bearing cover provide stable support for the camshaft. The bearing cover, in conjunction with the bearing housing, forms a sealing structure to prevent lubricating oil leakage and to prevent dust and impurities from entering the bearing, thus avoiding accelerated wear due to contamination, ensuring good lubrication and a suitable working environment for the bearing, and extending its service life.

[0003] For example, a cam bearing cover with prior art disclosure number CN221074400U improves the overall strength of the cam bearing cover by setting horizontal, vertical and diagonal reinforcing ribs in the connecting part, thereby improving the rigidity of the camshaft installation, reducing the axial movement of the camshaft, and the cam bearing cover has a simple structure and is easy to process.

[0004] However, the existing technology described above still has the following problems in use: after long-term use, the cam bearing cover and cam will experience abnormal temperature rise due to poor lubrication, excessive friction, etc., and prolonged high temperature environment will cause damage to the bearing cover and cam, affecting their service life. Based on this, the present invention provides a cam bearing cover with a long service life. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a cam bearing cover with a long service life. By using a detection head at the bottom of a temperature sensor to monitor the internal temperature of the cam bearing cover body in real time, abnormal temperature rises caused by poor lubrication, excessive friction, or other reasons can be detected in a timely manner. This allows staff to take timely measures for maintenance and upkeep, preventing damage to the bearing cover and camshaft caused by high temperatures, thus extending their service life and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-service-life cam bearing cover, comprising a cam bearing cover body, a detection groove machined on the top of the cam bearing cover body, a detection hole opened at the bottom of the detection groove, a detection component provided inside the detection groove, the detection component including a temperature sensor, a detection head fixedly provided at the bottom of the temperature sensor, the bottom of the detection head penetrating the detection hole, a fixing component fixedly embedded on both the front and rear sides of the cam bearing cover body, the fixing component including a fixing block, a cavity provided inside the fixing block, an insert block slidably provided inside the cavity, slots opened on both the front and rear sides of the temperature sensor, the insert block penetrating the fixing block and inserting into the slot.

[0007] In a preferred embodiment, two fixed blocks are provided with a lever on the side away from each other. Multiple connecting rods are fixed between the lever and the insert block. Each connecting rod is fitted with a compression spring on its outer side. The two ends of the compression spring are fixed to the insert block and the inner wall of the cavity, respectively. The compression spring supports the insert block, thereby ensuring the stable insertion of the insert block into the slot.

[0008] In a preferred embodiment, both dial plates are fixedly provided with movable handles on their outer walls, and fastening bolts are provided above the movable handles. The dial plates are detachably connected to the fixing blocks by the fastening bolts. The use of fastening bolts can improve the fixation of the dial plates, thereby further improving the stability of the insert blocks.

[0009] In a preferred embodiment, a sealing ring is provided between the detection head and the detection hole. The number of sealing rings is two, and the two sealing rings are distributed vertically inside the detection hole. The sealing rings are used to improve the sealing between the detection head and the detection hole to prevent leakage problems.

[0010] In a preferred embodiment, reinforcing ribs are fixedly provided on both sides of the bottom of the cam bearing cover body, and two fixing holes are machined at the bottom of each reinforcing rib for installing the cam bearing cover body for use.

[0011] In a preferred embodiment, the cam bearing cover body has storage grooves on both sides of its top, which communicate with the fixing holes. The two storage grooves are located on both sides of the detection groove. The storage grooves can accommodate the bolts installed in the fixing holes to prevent the bolts from loosening due to collisions caused by exposure, thereby improving the stability of the cam bearing cover body installation.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model sets a temperature sensor in the detection groove at the top of the cam bearing cover body and uses the detection head at the bottom of the sensor to monitor the internal temperature of the cam bearing cover body in real time. This allows for timely detection of abnormal temperature rises caused by poor lubrication, excessive friction, etc., which facilitates timely maintenance and upkeep by staff, preventing damage to the bearing cover and camshaft caused by high temperature and extending their service life.

[0014] 2. The temperature sensor is fixed by the inserts in the two fixing blocks. Pulling the lever moves the inserts into the cavity, which makes it easy for the staff to quickly disassemble and replace the temperature sensor. At the same time, two sealing rings are set between the detection head and the detection hole to provide a double seal and prevent leakage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a cam bearing cover with a long service life, including a cam bearing cover body 1. The bottom two sides of the cam bearing cover body 1 are fixedly provided with reinforcing ribs 9, and the bottom of the two reinforcing ribs 9 are machined with two fixing holes 10. The top two sides of the cam bearing cover body 1 are machined with storage grooves 11 that communicate with the fixing holes 10. The two storage grooves 11 are located on both sides of the detection groove 2. The cam bearing cover body 1 is reinforced by the reinforcing ribs 9, which can improve the strength of the cam bearing cover body 1 and thus improve the support stability of the cam bearing cover body 1 for the cam.

[0025] Next, a detection groove 2 is machined on the top of the cam bearing cover body 1. A detection hole 3 is opened at the bottom of the detection groove 2. A detection component 4 is provided inside the detection groove 2. The detection component 4 includes a temperature sensor 41. A detection head 42 is fixedly provided at the bottom of the temperature sensor 41. The bottom of the detection head 42 passes through the detection hole 3.

[0026] The cam bearing cover body 1 is fixedly embedded with a fixing component 5 on both the front and rear sides. The fixing component 5 includes a fixing block 51. The fixing block 51 has a cavity 52 inside. An insert block 53 is slidably disposed inside the cavity 52. ​​The temperature sensor 41 has slots 54 on both the front and rear sides. The insert block 53 passes through the fixing block 51 and is inserted into the slot 54.

[0027] A sealing ring 8 is provided between the detection head 42 and the detection hole 3. There are two sealing rings 8, which are distributed vertically inside the detection hole 3. By setting two sealing rings 8, the sealing performance between the detection head 42 and the detection hole 3 can be improved.

[0028] In actual use, the temperature sensor 41 installed in the detection slot 2 monitors the temperature inside the cam bearing cover body 1 in real time through the detection head 42 at its bottom. When the temperature is detected to be too high or too low, the temperature sensor 41 transmits the signal data to the cam control system, so that the staff can take corresponding measures in time to avoid damage to the cam bearing cover body 1 and the cam in abnormal temperature environment, thereby improving the service life of the cam bearing cover body 1 and the cam.

[0029] Refer to the instruction manual appendix Figures 1-5 Each of the two fixed blocks 51 is provided with a lever plate 55 on a side away from each other. Multiple connecting rods 56 are fixed between the lever plate 55 and the insert block 53. A compression spring 57 is sleeved on the outside of each connecting rod 56. The two ends of the compression spring 57 are fixed to the insert block 53 and the inner wall of the cavity 52, respectively. Furthermore, a movable handle 6 is fixed on the outer wall of each of the two lever plates 55. A fastening bolt 7 is provided above the movable handle 6. The lever plate 55 is detachably connected to the fixed block 51 through the fastening bolt 7.

[0030] When the temperature sensor 41 needs to be replaced, the operator first loosens the fastening bolt 7 on the lever 55, then pulls the lever 55 to move the insert 53 connected by multiple connecting rods 56 out of the slot 54, so that the temperature sensor 41 can be taken out of the detection slot 2. Then, the operator pulls the lever 55 again to move the insert 53 into the cavity 52 of the fixing block 51. At this time, the compression spring 57 between the insert 53 and the cavity 52 is squeezed. After the new temperature sensor 41 is placed, the lever 55 is released. When the multiple compression springs 57 return to their original deformation, they push the insert 53 into the slot 54, thus fixing the temperature sensor 41. The structure is simple and the installation and disassembly are very quick.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
