What is a belt tensioner?The tensioner is a belt
tensioning device belonging to the automobile transmission system.
It is mainly composed of a fixed housing, a tensioning arm, a wheel
body, a torsion spring, a rolling bearing and a spring sleeve. The
belt tensioner is used to adjust the tightness of the belt, reduce
the vibration of the belt during operation and prevent the belt
from slipping to a certain extent, ensuring the normal and stable
operation of the transmission system. It is generally replaced
together with the belt, idler and other cooperative accessories.
The belt is a wearing part in automobile parts. When the belt is
used for a long time, it is prone to wear. When the groove of the
belt is worn deep and narrow, it will appear to be stretched. At
this time, a hydraulic unit or damping needs to be performed
through a tensioner. Spring, and the tensioner wheel can
automatically adjust according to the degree of wear of the belt.
Therefore, the belt tensioner wheel installed on the car can make
the belt run more smoothly, reduce noise and prevent slipping.The
principle of belt tensioner:The belt tensioner requires a certain
amount of torque to maintain the proper tension of the belt during
use and avoid belt slippage and elongation caused by aging or wear.
When the belt tensioner is running, the belt can cause vibration in
the tensioner, which will accelerate the wear of the belt and the
tensioner. Therefore, in order to avoid this situation, we need to
add a resistance mechanism to the tensioner. However, because
the belt tensioner is affected by different parameters,
its relationship with torque and resistance is complicated. The
change in torque directly affects the change in resistance, and is
the main factor affecting resistance. The parameters of the torsion
spring are also the main factor affecting torque. Therefore, in
order to better improve the resistance value of the belt tensioner,
it is necessary to appropriately reduce the pitch diameter of the
torsion spring.The main function of the belt tensioner is to adjust
the tightness of the timing belt, reduce the vibration of the belt
during operation, prevent the belt from slipping and ensure the
normal and stable operation of the transmission system. Although
the belt tensioner pulley has powerful performance, its service
life is short. Many car owners complain that the belt
tensioner is broken before the belt is broken. When this
happens, the timing belt and tensioner pulley should be replaced
together. Therefore, HDAG tensioner suggest that under
normal circumstances, the belt tensioner should be replaced every
3-5 years or about 80,000-100,000 kilometers. Please refer to the
vehicle maintenance manual for the specific replacement time.Why
