Description

Technical Field

[0001] The utility model belongs to the technical field of input shaft welding, in particular to a planetary reducer input shaft welding device. Background Art

[0002] A planetary reducer is a power transmission mechanism that uses a gear speed converter to reduce the motor's rotation speed to the desired number of rotations and obtain a larger torque. Correct installation, use and maintenance of the reducer are important links to ensure the normal operation of mechanical equipment. When the input torque is greater than the bearing torque, the input shaft of the planetary reducer is prone to breakage. Sometimes, in order to save costs or when there is a lack of accessories, the broken input shaft needs to be welded.

[0003] When welding the input shaft of a planetary reducer, friction welding is partially used. In this case, the sun gear needs to be clamped and rotated, and the input shaft needs to be fixed at the same time so that the ends of the two can be friction welded. When fixing the input shaft, some devices use bolt rod locking. This method requires the bolt rod to be rotated when disassembling and assembling the input shaft, which is inconvenient. Therefore, a planetary reducer input shaft welding device is needed, which can quickly lock the input shaft in place, thereby reducing the time spent on disassembling and assembling the input shaft during welding.
