The drive path of transmission system:
Motor → small belt pulley → vee belt → big belt pulley → retarder → commutation transmission shaft → right angle gear box → two planetary pinion counter-rotation, two pin gear rings maintain static → the reciprocal lifting of reversing gear bracket → broadband drive beam hanger oil pumping.
The motion principle of transmission system:
When two planet wheels (19) are done the opposite direction rotation, because planetary pinion is meshed with pin gear ring (6) on two parallel symmetries and the fixed rectangular ring track (5), move at the uniform velocity along the straightway of pin gear ring so drive reversing gear bracket (7) and top balancer weight (17) thereof, motor (15), retarder (11) etc., its motion equation is:
y＝v.t+f(x)
The y-displacement
V-straightway speed (m/s)
The t-time (s)
The equation of f (x)-pin gear ring curved section, f (x) designs as required, and it can be circular function, elliptic function, centroid etc.Make f (x) be circular function, when planetary pinion moved to the upper and lower dead point of pin gear ring, the V=0 of commutator was so the smooth steady nothing that commutates is impacted.
The reversing principle of transmission system:
Two planetary pinions rotate in pin gear ring separately in the other direction, making constant speed along the straightway of pin gear ring simultaneously rises, after rising to the straightway end, the commutation beginning, two right angle gear boxs move as opposing parallel, and reversing shaft endwisely slips in the driven wheel of speed reducer thereupon, reversing gear bracket is made speed change at the curved section of 1/4 circle and is risen, to peak commutator speed V=0, at this moment, two right angle gear boxs are parallel side by side; Planet wheel be rotated further then realize reversing gear bracket the curved section of other 1/4 circle do speed change descend, when reducing to the opposite side straightway of pin gear ring, commutation finishes, reversing gear bracket begins to do constant speed and descends, and reduces to after straightway finishes commutation beginning for the second time.Reversing gear bracket is made speed change and is descended, when reducing as far as possible, reduction of speed V=0, at this moment, two right angle gear boxs are parallel side by side, continue again transmission then reversing gear bracket begin speed change and rise, when rising to curved section and finishing, commutation for the second time also finishes.So go round and begin again, realize the reciprocal lifting of reversing gear bracket.
