Description

Technical Field

[0001] This utility model relates to the field of drive shaft technology, and in particular to a drive shaft that is easy to connect. Background Technology

[0002] The drive shaft is a type of working device for a loader. It is a device that can propel the loader smoothly, allowing the drive wheels to rotate at different angular velocities. The drive shaft is subjected to alternating stresses such as torsion, shear, tension, compression, and impact. It can also cause torsional and bending vibrations of the drive shaft, generating additional stress. The stress distribution is uneven, and there is sliding friction between the drive shaft journal and the bearing.

[0003] Existing drive shaft assemblies require mounting brackets to be installed on the engine. During use, a secondary docking is necessary to transmit power to the engine output, which is generally too cumbersome and complex. Therefore, a drive shaft that is easy to dock is needed to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing a drive shaft that is easy to connect.

[0005] To address the aforementioned issues, a drive shaft that facilitates docking is provided. The shaft comprises a docking seat, a drive shaft, and bearings. The multiple drive shaft connection ends are all semi-cylindrical. A connecting ring is provided near the semi-cylindrical end of each drive shaft. The connecting ring is welded to the drive shaft, and bolts are provided on the connecting ring to securely connect the drive shaft to be docked.

[0006] Preferably, the sides of the multiple sets of drive shaft docking positions are provided with positioning grooves.

[0007] Preferably, positioning rubber rings are provided in the multiple sets of drive shaft positioning grooves.

[0008] Preferably, a bearing is provided outside the positioning rubber ring.

[0009] Preferably, the outer surface of the bearing is fitted into the mating seat structure.

[0010] In summary, the beneficial effects of this utility model are:

[0011] This utility model modifies some structures to allow drive shafts to be connected together by bolts. Bearings are provided at weak points in the drive shaft connection to prevent bolts from loosening and causing danger during long-term operation of one end of the drive shaft. The drive shaft connection method is simple, robust, and can meet daily use needs. Attached Figure Description
