Embodiment Construction
[0020] figure 1 It is a schematic diagram of the test gear train of the present invention: 1-crankshaft pulley 2-fan pulley 3-generator 4-water pump 5-automatic tensioner 6-belt, the embodiment of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] figure 2 It is a schematic diagram of the swing angle of the tensioner wheel movement of the present invention: 5a is the tensioner wheel mounting seat, 5b is the tensioner wheel, θ is the swing angle of the tensioner wheel, and r is the swing radius of the tensioner wheel.
[0022] 1: Test method for the jitter of the front wheel train belt of the engine:
[0023] see figure 1 , Test the amount of belt vibration D between the crankshaft pulley 1 and the fan pulley 2.
[0024] When the engine is stopped, the maximum span of the belt in the entire wheel train is taken as the test object, and a test mark is made at the middle position of the test belt.
[0025] Take the mi...
