Belt pulley bolt screwing machine can be divided into semiautomatic equipment and fully-automatic equipment, semi-automatic or full-automatic to then selecting, and tie
The yield of product is closed, the structure of product, the combined factors such as cost budgeting consider to select.
Damper pulley spoke hole A/F is narrow and small and its spoke hole pitch-row is also narrow and small, but it tightens bolt accordingly
Required technique torque ratio is larger, because belt pulley spoke hole A/F is narrow and small, to be inserted into spoke hole using counter-force arm
In come limit its motion, that is, equilibrant force is provided, then the size of counter-force arm is limited by the size of spoke hole, additionally due to spoke hole
Pitch-row is narrow and small to tighten sleeve etc. plus centre when tightening provided with bolt, and in summary restraining factors, have just limited counter-force arm
Size can not be too big, too big to be then fitted without fixed space with tightening sleeve interference or be inserted into spoke hole, due to
Technique torque ratio needed for tightening belt pulley bolt is larger and spoke hole pitch-row is narrow and small, to balance its moment of torsion, according to counter-force arm work
Mechanical relationship principle when making, then in the case of the limited size of counter-force arm, the length of counter-force arm can not be oversize, otherwise accordingly
Belt pulley counter-force arm can be twisted into two parts, therefore, directly set when being tightened in counter-force post insertion spoke hole to limit belt pulley bolt
Counter-force, there is difficulty, set it is too small can be twisted into two parts, set to moment of torsion can be born a little louder, space be fitted without again, at present
Traditional belt pulley bolt screwing machine, in face of big technique screw-down torque, and belt pulley spoke hole A/F is narrow and small, spoke
Hole pitch-row also balances torsion when tightening belt pulley bolt using fixed crankshaft flywheel end under narrow and small such a case, often
Square, this method adds parts in structure so that whole equipment is more complicated.

Transition disc 3 is pressed on belt pulley end face all the time when working, hence in so that the length of counter-force arm 2 can be very short, so in counter-force
In the case of the shape size of arm 2 is restricted, being allowed to the external force born can be bigger, and the dot that can be done due to it, because
And strong installing space, counter-force transition disc 3 is connected with guide rod 10, and guide rod 10 is coordinated with guide pin bushing 13 using small―gap suture, guide rod 10
It can be moved with respect to guide pin bushing 13, guide pin bushing 13 is installed in counter-force limited post and tightened on limit base 9, therefore guide pin bushing 13 is limited with counter-force
Position post position is determined, and then guide rod 10 is determined with counter-force limited post position, and then counter-force transition disc 3 and counter-force limited post position are true
Fixed, counter-force transition disc 3 can be moved relative to counter-force limited post along guide pillar direction, and the hole opened on counter-force transition disc 3 can be with
With counter-force limited post fit, when tighten sleeve just will be with being tightened threaded bolt contacts when, counter-force transition disc 3 with damper pulley 1
The distance of binding face to the end face of counter-force limited post is equal to distance to be compressed when tightening axle works, when belt pulley bolt is tightened
Moment of torsion suffered by belt pulley can be delivered to counter-force transition disc 3 by counter-force arm 2, and counter-force transition disc 3 is delivered to counter-force limited post 8,
Counter-force limited post 8, which is delivered to, tightens limit base 9, is finally delivered to by tightening limit base 9 in frame, so as to reach structure letter
Single, economical and practical effect, solves big technique screw-down torque, and belt pulley spoke hole A/F is narrow and small, spoke hole hole
Away from when also narrow and small such a case bottom pulley bolt is tightened, being balanced using belt pulley itself, screw-down torque is difficult to ask
