Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The transmission intermediate shaft capable of being converted comprises a main shaft 1, wherein at least two groups of through holes 3 are formed in the main shaft 1, a conversion pipe 2 is arranged on the main shaft 1, the inner diameter of the conversion pipe 2 is equal to the outer diameter of the main shaft 1, the conversion pipe can be sleeved outside the main shaft 1, and the conversion pipe can be fixed on one group of through holes 3 through screws 8. A gear set is arranged outside the switching tube 2 and comprises a second gear 10, a third gear 11, a fourth gear 12 and a fifth gear 13.

Wherein, the conversion tube 2 is provided with a plurality of steps 9 for the second gear 10, the third gear 11, the fourth gear 12 and the fifth gear 13 to be respectively arranged.

At least two groups of fixing holes 4 are formed in the main shaft 1, and each group of fixing holes 4 corresponds to the through hole 3. The main shaft 1 is fixedly provided with a stop ring 5 through a screw 8, and one end of the conversion tube 2 is abutted against the stop ring 5. The conversion tube 2 is provided with a screw hole 6 towards one end of the stop ring 5, a transverse hole 7 is arranged on the stop ring 5, and a screw 8 extending to the screw hole 6 for fixing is arranged on the transverse hole 7.

A synchronizer 14 is arranged between the second gear and the third gear 11, a bearing inner ring 17 is arranged at the front end of the conversion tube 2, and a thrust pad 18 is arranged between the bearing inner ring 17 and the second gear 10. Needle bearings 15 are arranged between the switching tube 2 and the second gear 10 and the third gear 11. Wherein a bush 19 is arranged on the switching tube 2 at the inner side of the roller bearing where the two-gear 10 is located.

A snap ring 16 is provided at the bottom of the needle bearing 15 where the third gear 11 is located in the direction of the fourth gear.

When the switching tube is used, the switching tube 2 is installed on the main shaft 1 at different positions according to the distance between the first shaft and the second shaft of different models, and is firmly fixed by the screws 8. The stop ring 5 corresponding to the position of the switching tube 2 is fixed on the fixing hole 4 and fixed with the switching tube 2 to increase the overall firmness. To increase the structural rigidity of the transition pipe 2 and the blocking ring 5, the perforations 3 should be arranged uniformly around the main shaft 1, preferably in six groups in the same radial plane.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
