Embodiment
Below with reference to the accompanying drawings with reference to illustrating that precompressed compensates structure love and the principle of the gap speed reducer that disappears.
First with reference to figure 1 structure, 1 determines gear ring and shell is fixed, and 2 dynamic gear rings and output terminal are fixed, and 3 and 4 are and the planet tooth determined gear ring and engage, and 5 and 6 is the planet teeth engaged with dynamic gear ring, and 3 and 5,4 and 6 are two groups coaxially fixes the different gear of the number of teeth.For ensureing the engagement of each group of profile of tooth, necessarily require outer ring tooth to be the same with the number of teeth difference of planet tooth, and the number of teeth of determining Chi Hedong outer ring, outer ring tooth is different.By changing dynamic outer ring tooth, the number of teeth difference of the number of teeth of determining outer ring tooth and outer ring tooth and planet tooth changes speed ratio and direction.7 interlock teeth are engaging of retainer of linking with left and right, its function is: allow the two groups of planetary pinions in left and right rotate in the gap that 1, disappears process simultaneously, left and right interlock retainer synchronous rotary is allowed by rotating shaft transmitting torque, latch during to eliminate input end clockwise and anticlockwise when 2, inputting forward or reverse.10 loaded springs promote left and right interlock retainer around the shaft pivot thus drive planet wheel rotate a certain angle in the opposite direction.
During rotating shaft, moment is by interlock tooth transmission planet-gear, and planet wheel is both rotation around determining gear ring revolution, can show that the angle of dynamic gear ring rotation of turning around is revolved in rotating shaft by difference tooth motion calculation.
If: 1 determines gear ring number of teeth m
2 dynamic gear ring number of teeth n
The number of teeth a of 3 planet wheels one and 4 planet wheels two
The number of teeth b of 5 planet wheels three and 6 planet wheels four
The relation of equal quantity that must reach under identical modulus:
Difference number of teeth c=m-a=n-b
m-n＝a-b
Rotation angle=the 360*c/a of turn around planet wheel one and planet wheel two is revolved in rotating shaft
Rotation angle=the 360*c/b of turn around planet wheel three and planet wheel four is revolved in rotating shaft
The poor number of teeth=360c/a-360c/b that planet wheel three and planet wheel four public affairs turn around is again divided by 360/b
The above abbreviation gained of the per tooth number of degrees that the poor number of teeth that equal the number of degrees of dynamic ring gear against rotation planet wheel three and planet wheel four public affairs turn around is multiplied by dynamic gear ring sets out the formula of the ring gear against rotation number of degrees
360bc/an-360c/n
With reference to figure 2, the Left-wing Federation at two ends moves between retainer and between right interlock retainer and coaxially installs the planet wheel that interfixes, and center can swing around the shaft.Retainer moves in the Left-wing Federation and right interlock retainer keeps synchronous by the engagement of interlock tooth.First compress loaded spring and again gap-eliminating structure is fit into dynamic gear ring and determine in gear ring, then unclamp loaded spring and promote left and right interlock retainer by it and freely rotate, until stop motion completes the gap that disappears.
When loaded spring promotes left and right interlock retainer by contrary reversing motion, planet wheel rotates with contrary direction in respective gear ring, by the flank of tooth of transmission planetary tooth of difference tooth with fixed and moving gear ring with contrary flank of tooth pressing, and Impact direction is contrary, the gap thus realization disappears.Pressure force and speed ratio are directly proportional.Dynamic gear ring can realize the effect identical with determining gear ring by the active force of the tooth that links too with the pressure force of planet tooth.
