[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] like Figure 1-Figure 14 As shown, the chain guide assembly of the utility model includes two chain guide plates arranged at intervals; a ceramic plate is clamped on one side corresponding to the two chain guide plates, and damping glue is bonded between the ceramic plate and the chain guide plates; a resistance adjusting screw is connected to the chain guide plate, and the resistance adjusting screw is in conflict with the ceramic plate, and the distance between the chain guide plate and the ceramic plate can be adjusted by rotating the resistance adjusting screw.
[0033] The material of the chain guide plate can be aluminum alloy, magnesium alloy, carbon fiber, or other materials commonly used in the art, and no specific restrictions are made here. Aluminum alloy, magnesium alloy, and carbon fiber have high strength and light weight. The material of the ceramic plate can be ceramic, which has good wear resistance and corrosion resistance. By respectively arranging ceramic plates on the corresponding sides of the two chain guide plates, the wear resistance and corrosion resistance of the chain guide plates can be improved, the wear of the chain on the chain guide plates can be reduced, and the service life of the chain guide assembly can be increased.
[0034] The chain guide plate and the ceramic plate are not rigidly connected, but are bonded together by damping rubber. The damping rubber is elastic, which can form an elastic connection between the chain guide plate and the ceramic plate. The elastic damping rubber can absorb vibration and impact force, and can play a role in shock absorption and buffering. It can buffer the contact vibration of the chain on the chain guide plate during speed change, and can reduce the noise generated by the chain contacting the chain guide plate during speed change.
[0035] In addition, by turning the resistance adjusting screw, the tightness of the resistance adjusting screw against the ceramic plate can be adjusted, thereby adjusting the damping of the damping rubber. The damping of the damping rubber will affect the speed of the chain. Users can adjust the damping by turning the tightness of the resistance adjusting screw according to their needs. For example, if the resistance adjusting screw becomes less in contact with the ceramic plate, the damping of the damping rubber can be reduced, the vibration absorption can be stronger, and the chain can be slowed down.
[0036] The damping rubber is provided with an avoidance through hole for avoiding the resistance adjusting screw, the aperture of which is greater than or equal to the outer diameter of the resistance adjusting screw, and the resistance adjusting screw passes through the avoidance through hole and contacts the ceramic plate. The resistance adjusting screw does not contact the damping rubber and will not affect the damping of the damping rubber.
[0037] The two chain guide plates are defined as a first chain guide plate 10 and a second chain guide plate 20, the head of the first chain guide plate 10 and the head of the second chain guide plate 20 are connected by a first connecting plate 24, and the tail of the first chain guide plate 10 and the tail of the second chain guide plate 20 are connected by a second connecting plate 25. The first chain guide plate 10 and the second chain guide plate 20 are connected to form an integral part, which can be integrally formed by a processing technology, or connected to form an integral part by other methods commonly used in the art, and no specific limitation is made here.
[0038] The ceramic plate engaged with the first chain guide plate 10 is defined as a first ceramic plate 30 . The first ceramic plate 30 extends from the head portion to the tail portion of the first chain guide plate 10 .
[0039] The ceramic plate engaged with the second chain guide plate 20 is defined as a second ceramic plate 40 , and the second ceramic plate 40 is disposed at the head of the second chain guide plate 20 .
[0040] The first chain guide plate 10 can move the chain on the small chain plate to the large chain plate. During the moving process, the chain contacts the first chain guide plate 10, and the chain contacts and rubs the first chain guide plate 10 along the length direction (from the head to the tail or from the tail to the head); therefore, a first ceramic plate 30 is arranged on the first chain guide plate 10, and the first ceramic plate 30 extends from the head to the tail of the first chain guide plate 10, and the chain contacts the first ceramic plate 30. The first ceramic plate 30 has good wear resistance, which can improve the wear resistance and corrosion resistance of the chain guide plate, reduce the wear of the chain on the chain guide plate, and increase the service life of the chain guide assembly.
[0041] The second chain guide plate 20 can move the chain on the large chain plate to the small chain plate. During the moving process, the chain only contacts the head of the second chain guide plate 20. Therefore, a second ceramic plate 40 is set at the head of the second chain guide plate 20, and the chain contacts the second ceramic plate 40. The second ceramic plate 40 has good wear resistance, which can improve the wear resistance and corrosion resistance of the chain guide plate, reduce the wear of the chain on the chain guide plate, and increase the service life of the chain guide assembly.
[0042] The first ceramic plate 30 has a plurality of first engaging grooves 31 at its edge, and the first chain guide plate 10 has a first engaging hook 11 engaged with the first engaging grooves 31. The first engaging hook 11 engages in the first engaging grooves 31, so that the first ceramic plate 30 can be engaged with the first chain guide plate 10.
[0043] The first engaging groove 31 is in a rectangular parallelepiped shape as a whole, and one groove wall of the first engaging groove 31 is open, and the first engaging hook 11 extends through the opening and engages in the first engaging groove 31. The inner groove walls of the first engaging groove 31 are rounded structures, and the inner groove walls of the first engaging groove 31 are connected in an arc shape, so that the first engaging hook 11 can be more smoothly and conveniently engaged and disengaged.
[0044] The first chain guide plate 10 is provided with a first deformation through hole 12, and the first engaging hook 11 is arranged at the edge of the first deformation through hole 12. By providing the first deformation through hole 12, the first engaging hook 11 can be squeezed, so that the first engaging hook 11 can be easily engaged and fixed in the first engaging groove 31, and then the first ceramic plate 30 can be easily engaged on the first chain guide plate 10.
[0045] The contact surface between the first engaging groove 31 and the first engaging hook 11 is bonded with a first auxiliary damping adhesive 14 , which can enhance the reliability of the engagement between the first ceramic plate 30 and the first chain guide plate 10 , so that the first ceramic plate 30 is firmly and effectively engaged on the first chain guide plate 10 .
[0046] The first ceramic plate 30 is provided with a first groove 32 matched with the first damping rubber 50, and the first damping rubber 50 is bonded and fixed in the first groove 32. By providing the first groove 32, the first damping rubber 50 can be limited, so that the first damping rubber 50 can be firmly and effectively bonded between the first ceramic plate 30 and the first chain guide plate 10.
[0047] A first resistance adjusting screw 13 is connected to the first chain guide plate 10, and a first avoidance through hole 51 for avoiding the first resistance adjusting screw 13 is provided on the first damping rubber 50; the aperture of the first avoidance through hole 51 is larger than the outer diameter of the first resistance adjusting screw 13, and the end of the first resistance adjusting screw 13 passes through the first avoidance through hole 51 and conflicts with the first ceramic plate 30.
[0048] By rotating the first resistance adjusting screw 13, the tightness of the first resistance adjusting screw 13 against the first ceramic plate 30 can be adjusted, thereby adjusting the damping of the first damping rubber 50. The damping of the damping rubber will affect the speed of the chain. The user can adjust the damping by rotating the tightness of the resistance adjusting screw according to the needs. For example, if the first resistance adjusting screw 13 is less in contact with the first ceramic plate 30, the damping of the first damping rubber 50 can be reduced, and the vibration absorption can be strengthened, thereby slowing down the chain speed.
[0049] The thickness of the first damping adhesive 50 is 0.2 mm-1.0 mm, which can give the first damping adhesive 50 a certain amount of pre-compression during assembly, thereby facilitating adjustment of the damping size.
[0050] The second ceramic plate 40 has a plurality of second engaging grooves 41 at its edge, and the second chain guide plate 20 has a second engaging hook 21 engaged with the second engaging grooves 41. The second engaging hook 21 engages in the second engaging grooves 41, so that the second ceramic plate 40 can be engaged with the second chain guide plate 20.
[0051] The second chain guide plate 20 is provided with a second deformation through hole 22, and the second engaging hook 21 is arranged at the edge of the second deformation through hole 22. By providing the second deformation through hole 22, the second engaging hook 21 can be squeezed, so that the second engaging hook 21 can be easily engaged and fixed in the second engaging groove 41, and then the second ceramic plate 40 can be easily engaged on the second chain guide plate 20.
[0052] The second engaging groove 41 is in a rectangular parallelepiped shape as a whole, and one groove wall of the second engaging groove 41 is open, and the second engaging hook 21 extends through the opening and engages in the second engaging groove 41. The inner groove walls of the second engaging groove 41 are rounded structures, and the inner groove walls of the second engaging groove 41 are connected in an arc shape, so that the second engaging hook 21 can be engaged and disengaged more smoothly and conveniently.
[0053] The contact surface between the second engaging groove 41 and the second engaging hook 21 is bonded with a second auxiliary damping glue 24, which can enhance the reliability of the engagement between the second ceramic plate 40 and the second chain guide plate 20, so that the second ceramic plate 40 is firmly and effectively engaged on the second chain guide plate 20.
[0054] The second ceramic plate 40 is provided with a second groove 42 matched with the second damping adhesive 60, and the second damping adhesive 60 is bonded and fixed in the second groove 42. By providing the second groove 42, the second damping adhesive 60 can be limited, so that the second damping adhesive 60 can be firmly and effectively bonded between the second ceramic plate 40 and the second chain guide plate 20.
[0055] A second resistance adjusting screw 23 is connected to the second chain guide plate 20, and a second avoidance through hole 61 for avoiding the second resistance adjusting screw 23 is provided on the second damping rubber 60. The aperture of the second avoidance through hole 61 is larger than the outer diameter of the second resistance adjusting screw 23, and the end of the second resistance adjusting screw 23 passes through the second avoidance through hole 61 and conflicts with the second ceramic plate 40.
[0056] By rotating the second resistance adjusting screw 23, the tightness of the second resistance adjusting screw 23 against the second ceramic plate 40 can be adjusted, thereby adjusting the damping size of the second damping rubber 60. The damping size of the damping rubber will affect the speed of the chain. The user can adjust the damping size by rotating the tightness of the resistance adjusting screw according to the needs. For example, if the second resistance adjusting screw 23 decreases the degree of resistance against the second ceramic plate 40, the damping of the second damping rubber 60 can be reduced, and the vibration absorption can be strengthened, thereby slowing down the chain speed.
[0057] The thickness of the second damping adhesive 60 is 0.2 mm-1.0 mm, which can give the second damping adhesive 60 a certain amount of pre-compression during assembly, thereby facilitating adjustment of the damping size.
[0058] like Fig.10 , Fig.12 As shown, the surface of the second ceramic plate 40 is provided with an arc-shaped protrusion 43. The arc-shaped protrusion 43 can limit the chain, prevent the chain from jumping, and avoid the chain from deviating from the chain guide plate assembly. In addition, the surface of the arc-shaped protrusion 43 is an arc-shaped curved surface, which can alleviate the wear of the arc-shaped protrusion 43 on the chain.
