Seat 1, the tolerances of housing 5, interior sliding shim 18, outer sliding shim 17, disk 16 on the axial direction of second axis 4, by
In design and the influence of manufacture, there is certain error, therefore can not ensure the assembling that gap is zero between rubbing surface after assembling,
Gap is produced, automatic tensioner can be caused to provide enough dampings, and produce abnormal sound；Interference is produced, it is particularly larger
Interference, automatic tensioner can be caused can not to work and fail.Therefore it is right using wavy spring 21 between base 1 and housing 5
Axial gap between pivot 3, rock shaft 11, base 1, housing 5, interior sliding shim 18, outer sliding shim 17, disk 16 is mended
Repay, axial direction designs between pivot 3, rock shaft 11, base 1, housing 5, interior sliding shim 18, outer sliding shim 17, disk 16
Certain gap, it is compressed axially after assembling after eliminating gap and continues to compress, the axial direction of wavy spring 21 is produced certain pressure
Contracting amount, produce certain pretightning force, it is ensured that pivot 3, rock shaft 11, base 1, housing 5, interior sliding shim 18, outer sliding mats
Suitable damping is produced between piece 17, disk 16.
The present embodiment when in use, by belt 15 be wrapped in starting-generating all-in-one belt pulley 20, shell ends tensioning wheel 10,
Between rock shaft end tensioning wheel 12, outside engine crankshaft belt pulley 22 and compressor of air conditioner belt pulley 23, when starting-generating one
When body machine is static to be needed to start, starting-generating all-in-one is used as motor first, is driven by starting-generating all-in-one belt pulley 20
First belt section 24 of belt 15, the tensioning of the first belt section 24 and passing power, belt 15 drive engine crankshaft belt pulley 22
Rotation, counterclockwise rotated under the tensile force effect of the belt section 24 of shell ends tensioning wheel 10 first, shell ends tensioning wheel 10
And left swing arm 7 is promoted to surround the first contour clockwise oscillation；Now the belt 15 of the second belt section 25 relaxes not passing power, empty
Compressor pulley 23 is adjusted to be turned clockwise in the presence of right swing arm 8, torsion spring 13 or scroll spring 14 around first axle 9,
Tightening belt 15, the relaxation shake of belt 15 is prevented, while apply certain tensile force to belt 15, improved power transmission, drive
Engine crankshaft belt pulley 22 rotates, and engine is reached starting speed within a very short time, reaches starting speed rear engine
Oil spout is lighted a fire, and starts to run well.
After engine oil spout, which is lighted a fire, to be started, starting-generating all-in-one switches to hair by control system under computer
Motor, compressor of air conditioner belt pulley 23 is driven to rotate by belt 15 by engine crankshaft belt pulley 22, the second belt section 25 is opened
Tight and passing power drives starting-generating all-in-one belt pulley 20 to rotate, and rock shaft end tensioning wheel 12 is in the tensile force of the second belt section 25
In the presence of, counterclockwise rotated around first axle 9, now the first belt section 24 relaxation shake, shell ends tensioning wheel
10 turn clockwise around first axle 9, tightening belt 15, prevent the relaxation shake of belt 15, while apply necessarily to belt 15
Tensile force, improve power transmission, drive starting-generating all-in-one belt pulley 20 to rotate, be in starting-generating all-in-one and generate electricity
State, supply vehicle electric equipment use；In starting-generating all-in-one constantly starting and power generation cycle, the first of belt 15
The belt section 25 of belt section 24 and second is in elastic alternating state repeatedly, and the shell ends tensioning wheel 10 and rock shaft of tightening belt 15
Tensioning wheel 12 is held, in both direction reciprocally swinging clockwise and anticlockwise, to enter also constantly around first axle 9 to belt 15
Row tensioning.
