Problems solved by technology

Nevertheless, the shaft tube structure of the motor still has problems in actual assembly or use, for example: the bearing 4 is only clamped by the inner wall of the clip 21 to form a position, and the bearing 4 does not actually contact the shaft tube 11 The inner wall of the shaft hole 111 makes the assembly reliability of the bearing 4 low; if the bearing 4 is an oil bearing, the shaft tube 11 and the buckle 2 cannot provide a closed oil s

Abstract

The invention is a motor shaft tube combined structure, containing a shaft tube, a fastener and a shaft sleeve. The inner wall of the shaft tube are formed with several grooves, several constant head tanks and several raised blocks. The fastener extends upwards from a seat to form sever fastening feet and there are several hooks formed on the tops of the fastening feet. The shaft sleeve is provided with a base and several spacing blocks, and can hold a bearing and forms an oil storage space. The shaft sleeve is arranged in the fastener and locates a retaining ring by the base. As the shaft sleeve and the fastener are inserted in the shaft tube, the hooks grips a rotor group outwards and grips the shaft sleeve inwards so that the shaft sleeve closely combines and locates the bearing.

Description

technical field [0001] The invention relates to a combination structure of a motor shaft tube, in particular to a buckle and a shaft tube using a shaft sleeve, which can improve the assembly reliability, increase the service life of the bearing, simplify the assembly process, and maintain the motor rotor. Combination structure of motor shaft tube for rotation balance and rotation stability. Background technique [0002] The combined structure of the shaft tube of the known motor, such as Taiwan No. 525872, a new patent titled "Shaft tube structure of the motor", please refer to Figures 1 and 2, the shaft tube structure of the motor includes a shell base 1 and a buckle Body 2. The casing 1 is provided with a shaft tube 11 having a shaft hole 111 . The inner wall of the shaft hole 11 has several grooves 112 , and the top of the groove 112 extends to form an open groove 113 . The buckle body 2 is provided with several clamping feet 22 on a base 21. The base 21 is clamped in t...
