Chain Assembly
Basic principle of conveyor chain tensioner
Pull out the locking rod, the plunger will extend out of the hole
under the mutual force of the plunger spring to rotate the pawl at
the locking plunger. At the same time, the oil pressure from the
engine will open the one-way valve, and the oil will immediately
enter the high-pressure chamber of the tensioner assembly through
the oil supply channel. The oil pressure of the high-pressure
chamber and the low-pressure chamber is equal. The tension force of
the tensioner is: oil pressure + spring force.
Compress the plunger, close the one-way valve, and
the oil in the high-pressure chamber is in a compressed state.
Since the compressibility ratio of the oil is small, a large
damping is formed. In the whole process of back pressure, the
plunger damping is large, reducing the amplitude and transmission
noise of the transmission chain. The excess oil leaks to the
outside of the assembly through the fitting clearance between the
plunger and the housing hole, playing the role of overpressure
protection and lubrication system.
