In order to facilitate positioning and improve assembly precision, a positioning boss is arranged at the center of the end face of one side of the shaft sleeve body, and the outer diameter surface of the positioning boss and the end face of the bearing body are in circular arc transition.
In order to prevent the end face of the shaft sleeve with the cyclone milling spiral groove from rotating relative to the corresponding connecting piece, two anti-rotation grooves are symmetrically formed in the positioning boss and are tangential grooves.
In order to enable the shaft sleeve to realize rotary motion, make a corresponding gear shifting shaft assembly to shift gears and improve the oil storage capacity of the shaft sleeve so as to prolong the service life of the shaft sleeve and further ensure the working stability of a gearbox, 6 cyclone spiral grooves which are uniformly distributed along the circumferential direction of the shaft sleeve body are formed in the inner hole arc surface of the shaft sleeve body, the spiral grooves and the end surface of the shaft sleeve body form a 45-degree angle, the bottoms of the spiral grooves are arc-shaped, and the spiral grooves are unfolded linearly when the shaft sleeve body is unfolded along the circumferential direction.
In order to ensure the best processing effect of the cyclone type spiral groove, the spiral groove is processed in a milling mode preferably, and other processing modes can be selected according to actual conditions.
Preferably, the radius of the groove bottom of the spiral groove is 2mm, the normal distance from the groove bottom to the inner diameter surface of the shaft sleeve body is 1mm, and the two sides of the spiral groove are transited to the inner diameter surface of the shaft sleeve body through arcs with the radius of 1 mm.
For convenient assembly, the shaft sleeve body is preferably provided with chamfers at two ends, and the chamfers form an angle of 30 degrees with the axis of the shaft sleeve body and have a height of 2 mm.
The utility model has the advantages that: the shaft sleeve with the cyclone milling spiral groove is simple in structure, and the anti-rotation groove formed in the tangential direction is designed on the positioning boss on the end face, so that the transmission reliability is improved; 6 spiral grooves which are uniformly distributed in a special processing mode, namely cyclone milling processing, are designed on the inner diameter surface of the shaft sleeve body, so that the rotary motion is realized, the corresponding gear shifting shaft assembly is manufactured to perform gear shifting action, and the transmission precision and efficiency are improved; in addition, the shaft sleeve with the cyclone milling spiral groove has the advantages of good oil storage effect, strong self-lubricating capability, long service life, simple manufacturing process and easiness in operation, greatly improves the efficiency of the production process and reduces the cost.
