Axial bearing structure and motor

Abstract

The invention provides an axial bearing structure and a motor. The axial bearing structure comprises an air bearing, a bearing base, an end cover and a heat conduction member, wherein the air bearing is connected with the bearing base, the air bearing comprises a first shaft hole, the heat conduction member is clamped between the bearing base and the end cover, and the heat conductivity of the heat conduction member is greater than that of the bearing base; and the heat conduction member comprises a first end and a second end, a solid extended structure is arranged between the first end and the second end of the heat conduction member, the first end is arranged at the position close to the first shaft hole relative to the second end or the position opposite to the outer circle of the first shaft hole in the axial direction, and the second end is arranged at the outer ring position close to the end cover relative to the first end or arranged at the outer ring position of the end cover. According to the axial bearing structure and the motor, good heat conduction and heat dissipation effects are effectively conducted on a bearing cone and other parts, and the cooling effect on the bearing is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an axial bearing structure and a motor. Background technique [0002] The current dynamic pressure air suspension axial bearing structure in the motor, see the original technology figure 1 , The overall structure in the motor is composed of an air bearing 101 , a bearing base 102 , a fastener 103 , and an end cover 104 . Among them, the air bearing 101 is usually fixed on the bearing base 102 by means of welding / clamping to form a whole bearing stator; the fastener 103 is usually a pin / screw, and the air bearing 101 and the bearing base 102 are integrally formed by the fastener 103 Fixed / limited to the end cover 104, as shown in the original technology figure 2 shown. [0003] The main defects of the original technical structure are as follows: [0004] 1. It is impossible to balance dynamic adaptability and reliability, and improper design will affect bearing performanc...
