Abstract
Title: Mounting and Positioning Structure of Motor Rotor Abstract The invention discloses a mounting and positioning strcture of a motor rotor. The structure comprises a shell provided with a bearing chamber, and an oil-retaining bearing is arranged in the bearing chamber which is internally provided with a clamping spring elastically clamped with the oil-retaining bearing. The oil-retaining bearing is of a two-step structure, the bearing chamber is of a two-step cavity formed on the shell, wherein the first step of the oil-retaining bearing is mounted in the first step cavity of the bearing chamber, the clamping spring is disposed in the second step cavity and clamped with the second step of the oil-retaining bearing, the first step of the oil-retaining bearing is used for realizing the rotation function of the oil-retaining bearing, and the second step of the oil-retaining bearing is used for realizing the buffering function and real-time automatic adjustment function of the oil-retaining bearing. The clamp spring elastically clamped with the oil-retaining bearing is arranged in the bearing chamber to absorb the impact of the motor rotor on the oil-retaining bearing, so as to reduce the abrasion. 2*5
Description
Description Mounting and Positioning Structure of Motor Rotor Technical Field The invention relates to a mounting and positioning structure of a motor rotor. Background of the Invention An oil-retaining bearing contains 10%-40% (volume fraction) lubricating oil therein because of having porosity of a sintered body and works in an oil self-supply state. The oil-retaining bearing has the advantages of low cost, vibration absorption, low noise and no need of adding lubricating oil in long-term operation, and is especially suitable for working environments of difficult lubrication or no dirty oil allowed. The oil-retaining bearing has wide application because of low manufacturing cost and convenient use. Motors containing oil-retaining bearings account for an increasing proportion in international motor industry, but the systems for motors containing oil-retaining bearings are in a low level in design and manufacture. An oil-retaining bearing is generally directly mounted in a bearing chamber of a shell, the movement of a rotor will generate a great impact on the bearing, and the poor impact resistance of the bearing accelerates abrasion. Summary of the Invention The object of the invention is to provide a mounting and positioning structure of a motor rotor, which has high impact resistance. In order to realize the above object, the invention employs the following technical scheme: a mounting and positioning structure of a motor rotor comprises a shell provided with a bearing chamber, characterized in that an oil-retaining bearing is arranged in the bearing chamber which is internally provided with a clamping spring elastically clamped with the oil-retaining bearing. Preferably, the oil-retaining bearing is of a two-step structure, the bearing chamber is of a two-step cavity formed on the shell, wherein the first step of the oil-retaining bearing is mounted in the first step cavity of the bearing chamber, the clamping spring is disposed in the second step cavity and clamped with the second step of the oil-retaining bearing, the first step of the oil-retaining bearing is used for realizing the rotation function of the oil-retaining bearing, and the second step of the oil-retaining bearing is used for realizing the buffering function and real-time automatic adjustment function of the oil-retaining bearing. Preferably, the clamp spring comprises a clamp ring, the inner side of the clamp ring is provided with at least three elastic clamp claws, and the tail ends of the clamp claws are butted against the outer diameter of the second step of the oil-retaining 1 bearing. The number of the clamp claws is six, and the six clamp claws are evenly distributed on the inner circumference of the clamp ring. With the above technical scheme, the clamp ring elastically clamped with the oil-retaining bearing is arranged in the bearing chamber to absorb the impact of the motor rotor on the oil-retaining bearing so as to reduce the abrasion. Brief Description of the Drawings The invention will be further described by combining the drawings and embodiment: FIG.1 is a schematic diagram of the assembly of the mounting and positioning structure of a motor rotor; and FIG.2 is a schematic diagram showing the mounting and positioning structure of a motor rotor after assembly. Detailed Description of the Invention FIG. 1 and FIG.2 show an embodiment of the invention of a mounting and positioning structure of a motor rotor. The mounting and positioning structure comprises a shell 2 provided with a bearing chamber 3, and an oil-retaining bearing 1 is arranged in the bearing chamber which is internally provided with a clamping spring elastically clamped with the oil-retaining bearing 1. The oil-retaining bearing is of a two-step structure, the first step of the oil-retaining bearing is used for realizing the rotation function of the oil-retaining bearing, and the second step of the oil-retaining bearing is used for realizing the buffering function and real-time automatic adjustment function of the oil-retaining bearing. The bearing chamber 3 is of a two-step cavity formed on the shell, wherein the first step 8 of the oil-retaining bearing is mounted in the first step cavity 7 of the bearing chamber, and the clamping spring is disposed in the second step cavity 6 and clamped with the second step 9 of the oil-retaining bearing. The clamp spring comprises a clamp ring 4, the inner side of the clamp ring is provided with at least three elastic clamp claws 5, and the tail ends of the clamp claws 5 are butted against the outer diameter of the second step of the oil-retaining bearing. The number of the clamp claws is six, and the six clamp claws are evenly distributed on the inner circumference of the clamp ring. 2
