[0002] The existing rotating spindle is subjected to eccentric force during the rotation process. In order to offset the eccentric force, the diameter of the rotating spindle must be increased, or the bearing and the bracket supporting the bearing must be designed to have high physical strength, which will greatly increase the cost of the equipment, increase the power loss, and increase the movement noise. Utility Model Content

[0004] The utility model solves the technical problem by adopting a technical solution: a driving structure of a main shaft of a vertical honing machine, which adopts a pulley assembly installed at the end of the main shaft, wherein the pulley assembly comprises a pulley, a pulley support sleeve, a pulley support bearing and a dial.

[0005] The pulley is connected to the driving device through a belt, the pulley is connected to the dial through a bolt, and the dial is connected to the main shaft through a bolt.

[0006] The pulley support sleeve is fixedly connected with the main shaft sleeve which is rotatably sleeved outside the main shaft by bolts.

[0007] The belt pulley is rotatably sleeved outside the belt pulley support sleeve through a belt pulley support bearing.

[0008] Furthermore, the pulley support bearing is separated into an upper pulley support bearing and a lower pulley support bearing by a pulley spacer.

[0009] The pulley spacer comprises an inner spacer and an outer spacer, which are concentrically arranged with a distance therebetween. The inner wall of the inner spacer is fitted with the outer wall of the pulley support sleeve, and the outer wall of the outer spacer is fitted with the inner wall of the pulley.

[0010] Furthermore, the dial is located at the upper end of the pulley and the upper end of the main shaft, and the dial, the pulley and the main shaft are concentrically arranged.

[0011] Furthermore, the number of the pulley support bearing above the pulley spacer is at least one, and the number of the pulley support bearing below the pulley spacer is at least one.

[0012] The significant effect of the utility model is that the deflection force transmitted from the driving device is eliminated through the pulley assembly, and there is no need to increase the diameter of the rotating main shaft, or design the bearing and the bracket supporting the bearing to have high-strength physical properties. The main shaft realizes transmission through the dial at the end, and the main shaft offsets the eccentric force brought by one side of the pulley through the cooperation of the pulley support sleeve and the pulley support bearing, thereby greatly improving the service life.
