In addition to family members, the excavator is probably the longest partner who accompanies the driver of the excavator. For long -term hard work, people will be tired and machines will wear. Therefore, many easy -to -wear parts need to be checked in time. These easy -to -wear parts include belts. So, how to adjust the tightness of the excavator power belt?
First of all, we must learn how to judge whether the belt is tight.
Check the tension of the belt first, and press the belt in the middle of the two belt wheels with a strong finger. The pressure is about 10kg (98N). If the pressure of the belt is about 15mm, the tension of the belt is just right. If the pressure is too large, the tension of the belt is not considered. If the belt has almost no pressure, the tension of the belt is considered too much. When tension is insufficient, the belt is prone to slipping. Excessive tension can easily damage the bearings of various auxiliary machines. Therefore, be sure to check and adjust the tension of the belt to the best state. If it is a new belt, the pressure is about 10-12mm, it is considered that the tension of the belt is just right.
The adjustment of the power belt assembly includes the adjustment of the newly installed belt, the re -tightness of the running belt, and loosening it in order to remove the belt.
Regarding the replacement method of power belts, first of all, you need to loosen the belt and place the manual valve on the manual hydraulic pump in the loose belt position. Then the manual pump until the belt is loosen to the extent that it is enough to remove it from the belt wheel. Before removing the belt, tighten some nuts to locate the motor base. After changing the belt, tighten the belt.
The tight adjustment steps are as follows: First, the manual valve on the manual hydraulic pump is placed in the band position. Then release some nuts and adjust to ensure the balance of loosening. During the tension process, the belt wheel must be rotated to make the load on the drive belt balanced. When the pressure is balanced, adjust the nut so that it is buckled on the motor base, and the motor base needs to be fixed. Then move the manual valve to the middle position to release the pressure of the hydraulic pump.
After the adjustment is successful, after two to three working classes, the belt is required to restart the pressure value of the old belt. If the belt is slippery during the normal operation of the second -hand excavator, the belt is tightly tightened, but do not exceed the given maximum pressure value.
How to adjust the tight belt of the excavator, did you learn? After reading this article, hurry up and check whether your beloved excavator needs to adjust the tightness of the belt. Thank you for your continuous attention to this site. I hope that in the future, I can provide more help for everyone in terms of engineering machinery operation skills.
