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. Example
[0017] like Figure 1-3 As shown, the utility model provides a clutch sealing seat, a sealing seat shell 1, a through hole 2 is provided in the middle of the sealing seat shell 1, an inner groove 3 is provided on the inner surface of the through hole 2, an inner hole 4 is provided in the sealing seat shell 1, a sealing assembly 6 is provided in the inner groove 3, a rubber ring 5 is fixedly connected to the inner surface of the sealing seat shell 1, the sealing assembly 6 includes a rubber pad 61, a connecting glue 62 and an elastic arc plate 63, a threaded rod 64 is rotatably connected to the middle of the outer surface of the rubber pad 61, a fixing seat 65 is provided on the outer surface of the threaded rod 64, and an extrusion spring 66 is sleeved on the outer surface of the threaded rod 64.
[0018] Specifically, the inner hole 4 is arranged on the outer side of the inner groove 3 , the rubber pad 61 is arranged in the inner cavity of the inner groove 3 , and the outer surface of the fixing seat 65 is fixedly connected to the inner surface of the inner hole 4 .
[0019] Specifically, the outer surface of the threaded rod 64 is threadedly connected to the inner surface of the fixing seat 65 .
[0020] Specifically, there are several rubber pads 61, and the intervals of the rubber pads 61 are connected by connecting glue 62. The outer surface of the elastic arc plate 63 is fixedly connected to the intervals of the rubber pads 61. The rubber pad 61, the connecting glue 62 and the elastic arc plate 63 form a circular ring.
[0021] Specifically, the end of the extrusion spring 66 is fixedly connected to the outer surface of the rubber pad 61 , and the end of the extrusion spring 66 away from the rubber pad 61 is fixedly connected to the inner surface of the inner groove 3 .
[0022] Specifically, the connecting glue 62 is made of silicone rubber glue.
[0023] The working principles and beneficial effects of the above embodiments.
[0024] When in use, the clutch is installed in the sealing seat housing 1, the outer surface of the clutch fits with the inner surface of the rubber ring 5, the clutch connecting shaft passes through the through hole 2, and the outer surface of the clutch connecting shaft fits with the inner surface of the whole composed of the rubber pad 61, the connecting glue 62 and the elastic arc plate 63. The threaded rod 64 is screwed to give the rubber pad 61 a thrust, so that the outer surface of the rubber pad 61 is tightly fitted on the outer surface of the clutch connecting shaft, so that the extrusion spring 66 is in a compressed state. When the rubber pad 61 is worn, the elastic force of the extrusion spring 66 can push the rubber pad 61, so that the worn rubber pad 61 is still fitted on the outer surface of the clutch connecting shaft. At the same time, since the initial arc surface of the elastic arc plate 63 faces the clutch connecting shaft, when the entire sealing seat and the clutch are installed together, the arc surface of the elastic arc plate 63 is squeezed and deformed, so that the elastic The outer surface of the arc plate 63 is in close contact with the surface of the clutch connecting shaft. The elastic arc plate 63 has elastic force due to being in a deformed state, so that the elastic arc plate 63 can always fit on the surface of the clutch connecting shaft, so that the number of rubber pads 61 occupies most of the area in the circular ring composed of the rubber pads 61, the connecting glue 62 and the elastic arc plate 63. The elastic arc plate 63 is in the gap between the multiple rubber pads 61, which can make the sealing component 6 as a whole have good firmness and not easy to be damaged, and the rubber pads 61 and the elastic arc plate 63 can fit on the surface of the clutch connecting shaft as much as possible, thereby improving the sealing of the entire sealing seat. Through the provided connecting glue 62, since the connecting glue 62 is made of silicone rubber glue, which is a polymer material that can be cured at room temperature, its cured product has extremely high elasticity, which facilitates the relative movement of the multiple rubber pads 61 due to vibration.
