Abstract
Description
Technical Field
[0001] The utility model relates to the field of rotor baking, in particular to a rotor baking bracket. Background Art
[0002] Rolling bearings are used at both ends of the rotor and are installed and fixed in the end covers of the motor housing. The rotor refers to a rotating body supported by bearings. When the unbalanced weight of the rotor is located in a parallel plane perpendicular to the rotation axis, the unbalanced weight will only appear after the rotor rotates. This dynamic imbalance is mostly eliminated by changing the weight and position of the balancing block to eliminate the inertial force and inertial force couple to achieve dynamic balance.
[0003] Currently, there is no special bracket for rotor baking on the market. Most manufacturers fix the rotor upright in a frame. This fixing method is not only cumbersome but also takes up a lot of space. It needs to be fixed with wire every time. Some repair manufacturers directly place the rotor on the bracket for horizontal baking instead of standing it upright. This baking method has a great influence on the balance of the motor. During the baking process, the paint will gather on the lower part of the rotor, causing the rotor to be eccentric, and cannot solve the problem of paint gathering on a part of the rotor during the rotor baking process.
[0004] Therefore, those skilled in the art provide a rotor baking support to solve the problems raised in the above background technology. Utility Model Content

There are also repair manufacturers who directly place the rotor on the bracket for horizontal baking without standing the rotor upright. This baking method has a great influence on the balance of the motor. During the baking process, the paint will gather at the lower part of the rotor, causing the rotor to be eccentric, and the problem of the paint gathering on the local part of the rotor during the rotor baking process cannot be solved.

Different specifications of brackets can be made according to the size of the rotor shaft diameter by changing the size of the base and the sleeve, which can be beneficial to the company's waste processing. At the same time, a brass protective sleeve is installed on the sleeve to protect the rotor shaft head from being damaged. The locking screw is inlaid with a copper protective sleeve, which will not cause damage to the shaft head when the screw is locked. When in use, the rotor can be directly placed in the sleeve body 2. After the rotor shaft is placed in the sleeve body 2, a 3mm copper plate is placed on the outside of the rotor shaft for protection to prevent damage to the rotor shaft head surface when the screw is locked.
