Anti- direction is rolled in dynamic gear ring and fixed tooth circle, each acts on dynamic gear ring and fixed tooth circle simultaneously from different directions, so that
Disappear gap.
Brief description of the drawings
Fig. 1 is the structure chart that precompressed compensates the gap reductor main body that disappears
1 fixed tooth circle 2 moves the planetary gear 47 of 25 planetary gear of gear ring 3 planetary gear, one 4 planetary gear 36 linkage tooth 8 Left-wing Federation
The linkage tooth rotating shaft of bearing 14 of 12 crossed roller bearing of dynamic right linkage retainer 10 pre-compressed spring, 11 rotating shaft of retainer 9 13
Fig. 2 is the schematic diagram in the compensation gap that precompressed compensates the gap reductor gap-eliminating structure that disappears
Embodiment
The structure love and principle for the gap reductor that disappears are compensated below according to the precompressed of accompanying drawing reference explanation.
With reference first to Fig. 1 structures, 1 fixed tooth circle is fixed with shell, and 2 dynamic gear rings are fixed with output end, and 3 and 4 are and fixed tooth circle
The planet tooth of engagement, 5 and 6 be the planet tooth engaged with dynamic gear ring, and 3 are two groups with 5,4 with 6 coaxially fixes the different tooth of the number of teeth
Wheel.To ensure the engagement of each group tooth form, must be requested that as outer ring tooth is with the number of teeth difference of planet tooth, and determine outer ring tooth and move
The number of teeth of outer ring tooth however it is the same.It is poor by the number of teeth for changing dynamic outer ring tooth, the number of teeth for determining outer ring tooth and outer ring tooth and planet tooth
To change gear ratio and direction.7 linkage teeth are engaged with the left and right retainer that links, and its function is：Allowed during the gap that 1st, disappears or so
Two groups of planetary gears rotate simultaneously, 2, input forward or reverse when moment of torsion transmitted by rotating shaft make left and right linkage retainer synchronous
Rotation, latch during eliminating input rotating.10 pre-compressed springs promote it is left and right linkage retainer around the shaft pivot so as to
Planetary gear is driven to rotate in opposite directions certain angle.
During rotating shaft, torque is both rotation around the revolution of fixed tooth circle by the tooth transmission planet-gear that links, planetary gear, passes through difference
Tooth motion calculation can show that the angle for dynamic gear ring rotation of turning around is revolved in rotating shaft.
If：1 fixed tooth circle number of teeth m
2 dynamic gear ring number of teeth n
The number of teeth a of 3 planetary gears one and 4 planetary gears two
The number of teeth b of 5 planetary gears three and 6 planetary gears four
The relation of equal quantity that must be reached under identical modulus：
Poor number of teeth c=m-a=n-b
M-n=a-b
Rotation angle=360*c/a of turn around planetary gear one and planetary gear two is revolved in rotating shaft
Rotation angle=360*c/b of turn around planetary gear three and planetary gear four is revolved in rotating shaft
The poor number of teeth=360c/a-360c/b that planetary gear three and the public affairs of planetary gear four turn around is again divided by 360/b
The poor number of teeth that the number of degrees of dynamic ring gear against rotation be equal to planetary gear three and the public affairs of planetary gear four turn around is multiplied by the every of dynamic gear ring
The formula of the ring gear against rotation number of degrees is set out obtained by tooth number of degrees above abbreviation
360bc/an-360c/n
With reference to Fig. 2, the Left-wing Federation at two ends is co-axially mounted the planet that interfixes between moving retainer between right linkage retainer
Wheel, center can be swung around the shaft.The Left-wing Federation moves retainer and right linkage retainer and keeps synchronous by the tooth engagement that links.Press first
Tight pre-compressed spring is installed gap-eliminating structure in dynamic gear ring and fixed tooth circle again, then unclamps pre-compressed spring left and right by its promotion
Dynamic retainer is freely rotated, until stop motion completes the gap that disappears.
When pre-compressed spring promote it is left and right linkage retainer press opposite counter motion when, planetary gear in respective gear ring with
Opposite direction rotates, and is pressed by the flank of tooth of the transmission planetary tooth of poor tooth with fixed and moving gear ring with the opposite flank of tooth, and stress side
To on the contrary, so as to realize the gap that disappears.Pressure force and fast ratio are directly proportional.The pressure force of dynamic gear ring and planet tooth can similarly pass through linkage
The active force of tooth can be realized and fixed tooth circle identical effect.
