Abstract
Title: An Improved Rotating Shaft Structure of Motor Rotor Abstract The invention discloses an improved rotating shaft structure of a motor rotor, which comprises a rotating shaft and a rotor mounted on the rotating shaft, wherein the outer side of the rotating shaft where a bearing is mounted is provided with a shaft shoulder structure. Because the shaft shoulder is disposed on the outer side of the rotating shaft of the motor rotor where a bearing is mounted, the shaft shoulder plays a role of positioning and bearing force after final assembly and thus protects the bearing.
Description
Description An Improved Rotating Shaft Structure of Motor Rotor Technical Field The invention relates to an improved rotating shaft structure of a motor rotor. Background of the Invention A motor rotor is one of important parts of a motor and comprises a rotor shaft, an iron core and a coil, wherein both sides of the rotating shaft need finish turning and are provided with bearings and then mounted on a motor shell. In the prior rotor shaft design, after the final assembly of the bearings, the outer end surface of the bearing is almost parallel to the end surface of the shaft, so when the motor shaft works, the axial movement of the rotating shaft will cause the impact force of the motor shell exerting on the shaft to directly act on the inner rings of the bearings, thereby accelerating the abrasion of the bearings, and even damaging the bearings. Summary of the Invention The object of the invention is to provide an improved rotating shaft structure of a motor rotor, which prevents impact between the inner ring of a bearing and a motor shell. In order to realize the above object, the invention employs the following technical scheme: an improved rotating shaft structure of a motor rotor comprises a rotating shaft and a rotor mounted on the rotating shaft, characterized in that the outer side of the rotating shaft where a bearing is mounted is provided with a shaft shoulder structure. Preferably, the end surface of the shaft shoulder is provided with a chamfer. Preferably, the outer diameter of the position of the rotating shaft fitting with the rotor is coated with an anaerobic glue layer. With the above technical scheme, the shaft shoulder structure disposed on the outer side of the rotating shaft of the motor rotor where the bearing is mounted plays a role of positioning and bearing force after final assembly and thus protects the bearing. Brief Description of the Drawings The invention will be further described by combining the following drawings and embodiment. FIG. is a structural diagram of the invention. Detailed Description of the Invention FIG.1 shows an embodiment of the invention of an improved rotating shaft structure of a motor rotor. The improved rotating shaft structure comprises a rotating shaft 1 and a rotor 5 mounted on the rotating shaft, and the outer side of the rotating shaft where a bearing is mounted 2 is provided with a shaft shoulder 3. The end surface of the shaft shoulder is provided with a chamfer 4. The outer diameter of the part of the 1 rotating shaft 1 fitting with the rotor 5 is coated with an anaerobic glue layer. 2
