Description
Technical field
The present invention relates to processing technique field is remanufactured, specifically idle pulley, which is remanufactured, uses submerged-arc welding flux cored wire.
Background technology
Idle pulley refers to the gear for playing transmission in the middle of two travelling gears not contacted with each other, while with the two teeth
Wheel engagement, for changing the rotation direction of driven gear, is allowed to identical with driving gear, and it is acted on simply, and change steering can not
Change gearratio.
Idle pulley is in the course of the work, it may appear that wear phenomenon, and the time one is grown, then motion transmission can be caused to go wrong, because
This is needed timely to change idle pulley, and this mode maintenance cost is higher, and the idle pulley after abrasion is not recycled,
The serious wasting of resources is caused, therefore, in the urgent need to a kind of method that can be recycled to idle pulley.
