Detailed Description
The utility model is described in further detail below with reference to the following figures and detailed description:
referring to fig. 1 to 4, the present invention provides a bearing axial distance compensation mechanism for an air compressor, which is disposed on a flange end cover 1 of the air compressor, and includes a compensation sleeve 2, the compensation sleeve 2 is screwed in a screw hole 4 at the outer side section of a central hole 3 of the flange end cover 1, the inner side section of the central hole 3 is provided with a bearing groove 5, an angular contact bearing 6 is arranged in the bearing groove 5, a part of an outer ring of the angular contact bearing 6 is provided with a projection area which is opposite to the screw hole 4, the inner end surface of the compensation sleeve 2 passes through the screw hole 4 to be matched and abutted against the outer ring 7 of the angular contact bearing 6, a plurality of clamping teeth 8 are evenly distributed on the outer end surface in a circumferential manner, a clamping groove 9 is arranged between every two adjacent clamping teeth 8, at least one bolt 10 is screwed at the position of the matched clamping groove 9 on the flange end cover 1, so that the axial distance between the compensation sleeve 2 and the opposite angle contact bearing 6 is quantified.
The compensation sleeve 2 is sleeved with an O-shaped ring 11, and the O-shaped ring 11 is sealed on the inner wall of the screw hole 4.
An inner hole of the compensation sleeve 2 is provided with an oil seal 12, and the outer end of the crankshaft is inserted in the oil seal 12.
The working principle of the bearing axial distance compensation mechanism on the air compressor is explained as follows:
according to the axial distance compensation mechanism for the bearing on the air compressor, the flange end cover 1 is a box body end cover of a power mechanism of the air compressor and is fixed on a box body through bolts, the angular contact bearing 6 is installed in the bearing groove 5 on the inner end face of the flange end cover 1, and the outer end of a crankshaft in the box body penetrates through the inner hole of the angular contact bearing 6 and extends to the oil seal 12 of the compensation sleeve 2.
After the installation targets in place, through rotatory compensation cover 2 for compensation cover 2 is rotatory along screw 4 in the circumference, then moves towards 7 terminal surfaces of outer lane of angular contact bearing 6 in the axial, until pressing at 7 terminal surfaces of outer lane of angular contact bearing 6, at this moment, according to design data, we can judge, with the spiro union point of bolt 10 on flange end cover 1 as the benchmark, every pass through a draw-in groove 9, how much distance then compensation cover 2 axial displacement, thereby realize that the axial distance that compensation cover 2 extrudes angular contact bearing 6 becomes ration, controllable, realize accurate compensation.
