Should the timing belt and timing pulley be lubricated after being used for a long time?
First of all, we know that lubrication is only required between metal and metal, and the timing belt is made of PU or rubber material and does not require lubrication for meshing transmission with the timing pulley.
The working principle of the timing pulley is to transmit power through the meshing of the teeth of the timing belt and the teeth of the timing pulley. This meshing method makes the timing pulley not require lubrication during operation. If lubrication is added between the timing pulley and the timing belt, it will affect the normal meshing effect, and the timing belt may slip, climb teeth, or even come out of the timing pulley.
Although the meshing transmission between the timing belt and the timing pulley does not require lubrication, it is necessary to ensure that the related components such as rolling bearings and sliding bearings are in good lubrication condition to reduce friction.
Rolling bearings: Rolling bearings usually need to be lubricated regularly to reduce friction and wear and extend service life.
Sliding bearings: Sliding bearings can be designed to be self-lubricating, but in some cases, lubricants may still need to be added to improve the lubrication effect.
Daily maintenance precautions to extend the service life of synchronous pulleys:
1. Synchronous pulley: Check whether there are any bumps on the surface of the synchronous pulley and whether there is any shaking during operation. If there is shaking, the synchronous pulley should be replaced in time.
2. Synchronous belt: The drive of the synchronous pulley depends on the synchronous belt, so the condition of the synchronous belt directly affects the performance of the synchronous pulley. Check the tension of the synchronous belt. Too tight will affect the speed, and too loose will cause slipping. If the belt is aged or the tension is insufficient, it needs to be replaced in time.
3. Cleaning and maintenance: Clean the synchronous belt and synchronous pulley regularly to avoid dust, grease and other contaminants from adhering; whether the mounting hole of the synchronous pulley is clean and free of impurities to prevent impurities from damaging the mounting hole; dirt and debris on the guide rails and rollers, keep them clean to reduce friction and wear.
