[0016] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the utility model technical scheme will be described clearly and completely in combination with the embodiment.
[0017] EMBODIMENT
[0018] As shown in Figure 1 , Figure 2 and Figure 3 , the bushing assembled compressor support comprises a static support 1 and a dynamic support 7, a connecting mechanism is mounted on the side wall of the static support 1, the connecting mechanism is mounted with a detachable vulcanized elastic piece 5, a fixed ring 8 is fixedly connected to the side wall of the dynamic support 7, and the fixed ring 8 is sleeved on the outer circle of the vulcanized elastic piece 5.
[0019] It should be noted that the static support 1, the dynamic support 7 and the fixed ring 8 are all integrally pressure cast, which can achieve high strength with light weight, the periphery of the vulcanized elastic piece 5 is wrapped with 3.9mm rubber, and the upper and lower ends have inclined angle guides to prevent rebound after pressing.
[0020] Specifically, the vulcanized elastic piece 5 is directly vulcanized by rubber, and then assembled with the connecting mechanism, so that the static support 1 and the dynamic support 7 are pressed and assembled to meet the performance, and the process is simple, the cost is low, the utilization rate is high, the size is easy to control, the product has good damping and vibration isolation performance, and the customer saves a lot of cost and improves customer satisfaction.
[0021] As shown in Figure 1 and Figure 3As shown, the outer ring of the vulcanized elastic member 5 is provided with a limiting groove 6, and the fixing ring 8 is in interference fit with the limiting groove 6.
[0022] It should be noted that the inner core of the vulcanized elastic member 5 has a wall thickness of 4.5mm at the middle part and a wall thickness of 3mm at the upper end.
[0023] Specifically, the fixing ring 8 is in interference fit with the limiting groove 6 of the vulcanized elastic member 5, so that after the dynamic support 7 is press-fitted with the static support 1, the dynamic support 7 has good vibration reduction and isolation performance. When disassembly is required, the vulcanized elastic member 5 can be separated from the dynamic support 7 only after the vulcanized elastic member 5 is removed from the static support 1 through the connecting mechanism.
[0024] As shown in Figure 1 , Figure 2 and Figure 3 , the connecting mechanism comprises an inner threaded cylinder 2 fixed on the side wall of the static support 1, the vulcanized elastic member 5 is sleeved on the outer ring of the inner threaded cylinder 2, the inner threaded cylinder 2 is threadedly connected with a fastening bolt 4, the outer ring of the fastening bolt 4 is fixedly sleeved with an anti-escape baffle 3, and the anti-escape baffle 3 abuts against the side wall of the vulcanized elastic member 5.
[0025] It should be noted that the side wall of the vulcanized elastic member 5 is provided with a plurality of protruding portions, so that when the anti-escape baffle 3 is driven to approach the side wall of the static support 1, the friction force can be increased through the protruding portions, so that displacement is not easy to occur, and the stability of the static support 1 after assembly with the dynamic support 7 is increased.
[0026] Specifically, rotating the fastening bolt 4 through the thread fit with the inner threaded cylinder 2 enables the fastening bolt 4 to only move in the inner ring of the inner threaded cylinder 2, thereby driving the anti-escape baffle 3 to approach or move away from the static support 1. First, the fastening bolt 4 and the anti-escape baffle 3 are detached from the inner threaded cylinder 2, and then the vulcanized elastic member 5 is installed on or removed from the inner threaded cylinder 2. Then, the fastening bolt 4 is inserted into the inner threaded cylinder 2, and the anti-escape baffle 3 is rotated to drive the anti-escape baffle 3 to approach the vulcanized elastic member 5 until the vulcanized elastic member 5 is firmly fixed between the static support 1 and the anti-escape baffle 3. Before the vulcanized elastic member 5 is installed on the inner threaded cylinder 2, the vulcanized elastic member 5 needs to be sleeved in the inner ring of the fixing ring 8 fixedly connected with the dynamic support 7.
[0027] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
