Description
Technical Field
The invention relates to the technical field of compressors, in particular to an anti-rotation mechanism of a compressor.
Background
The scroll compressor is generally composed of a movable scroll, a fixed scroll, an anti-rotation mechanism, an eccentric shaft, a bracket and the like. In the working process, the eccentric shaft drives the movable vortex disc to move, and the movable vortex disc vortex body is meshed with the fixed vortex disc vortex body to gradually compress gas. In the compression process, the rotation of the stop vortex disk is prevented to ensure that the movable vortex disk and the fixed vortex disk are correctly meshed. Common anti-rotation mechanism cross slip rings (also called as cross couplings), cylindrical pins, special mechanism ball bearings, small crankshafts and the like.
The existing cylindrical pin anti-rotation mechanism has two types: (1) The cylindrical pin is fixed on the movable disc, the support is provided with an opening, the cylindrical pin slides in the support hole, and the hole on the support limits the rotation of the brake vortex disc by limiting the cylindrical pin. (2) The cylindrical pin is fixed on the support, the movable plate is provided with an opening, the cylindrical pin slides in the movable plate opening, and the cylindrical pin limits the rotation of the brake vortex plate.
The existing ball bearing anti-rotation mechanism of the special mechanism is as follows: an annular fixed ring is fixed on each of the movable scroll and the support, a series of holes are formed in the annular fixed ring, and the balls are positioned in the holes and are tightly attached to the inner walls of the holes. The rotation of the annular fixed ring is limited by the balls, so that the rotation of the brake vortex disc is limited.
For the cylindrical pin anti-rotation mechanism, the hole diameter of the limiting cylindrical pin is relatively large, the hole precision requirement is relatively high, and the processing is difficult. During operation, the cylindrical pin slides along the inner wall of the movable hole, which can lead to abrasion of the hole. To reduce wear, the orbiting scroll bore may need to be further treated (e.g., a metal ring added to the bore) and added to the cost. Sliding friction is arranged between the cylindrical pin and the anti-rotation hole or between the cylindrical pin and the metal ring in the anti-rotation hole, so that friction loss is large, and working efficiency is affected. In addition, for the cylindrical pin anti-rotation mechanism, the joint surface of the bracket and the movable plate is in sliding friction in the working process, so that the friction loss is large, and the working efficiency is influenced.
For the ball bearing anti-rotation mechanism of the special mechanism, in order to ensure that the balls can work normally, the ball socket on the annular fixed ring needs high dimensional precision and position precision, so that the cost of the annular fixed ring is very high, and the whole compressor is easily damaged due to the precision problem. The annular fixed ring bears the anti-rotation force, and in order to prevent the annular fixed ring from being worn, the working procedures such as heat treatment and the like are needed, so that the manufacturing difficulty and the cost are further increased.
Therefore, the invention is mainly aimed at improving the cylindrical pin anti-rotation mechanism and the ball bearing anti-rotation mechanism of the special mechanism.
