Detailed description of the invention
Below in conjunction with the accompanying drawings and example, the utility model is described further.
Embodiment one (axle two ring):
As shown in Figure 1A to 1G, the ring type deceleration device of the present embodiment band return-stopping function includes upper-lower casing, and upper-lower casing forms cavity to accommodate correlated parts in wherein.
Eccentric shaft 3 is installed on lower house two side by bearing, and one end is stretched out housing and accepted input torque to connect driving means, and other end terminal position is sealed by eccentric shaft end cap 2.Each eccentric shaft 3 is provided with central shaft and two along the uniform eccentric wheel (being i.e. symmetricly set in the both sides of eccentric shaft axis, such as Fig. 1 C and Fig. 1 D) of axis circumference, and each eccentric wheel is all one-body molded with central shaft.
Output shaft 1 is installed on lower house two side by bearing, and its axis is parallel with the axis of eccentric shaft 3, and one end is stretched out housing and loaded output torque to connect, and an end cap 8 is sheathed on output shaft 1, and other end terminal position is sealed by output shaft end cap 6.Output shaft 1 part in the housing is provided with external gear.
Two internal tooth ring plates 4 connect eccentric shaft 3 and output shaft 1, as shown in Fig. 1 E, Fig. 1 F, each internal tooth ring plate 4 is provided with the through hole in order to match and ring gear with eccentric wheel, through hole be embedded by one that copper sheathing (being shown as black ring in the figure) inner surface that is fixed on internal tooth ring plate 4 formed (at low load conditions, copper sheathing can not also be embedded, but directly formed by internal tooth ring plate perforate).The through hole of each internal tooth ring plate 4 is set on corresponding eccentric wheel, makes eccentric wheel to rotate in sliding friction mode in through-holes.Each ring gear all engages with the external gear of output shaft, and ring gear is greater than external gear, and both form small Tooth Number Difference Planetary Transmission.180 degree are differed between each ring gear and the meshing point of external gear.Separated by a stripper loop 7 between two internal tooth ring plates 4, it is to avoid interfere.
As shown in Fig. 1 G, Fig. 1 H, Fig. 1 I, after installation, two eccentric shaft wheels are respectively symmetrically and are positioned at eccentric shaft axis both sides, and both differ 180 degree, and ring gear is also respectively symmetrically and is positioned at output shaft external gear both sides, the most also difference 180 degree.As shown in fig. 1h, for right internal tooth ring plate, eccentric shaft wheel is positioned at the rightmost side, and the ring gear of right internal tooth ring plate is positioned at the rightmost side, at this moment, is meshed with on the left of external gear on the left of ring gear；Equally, for left inside teething-ring plate, eccentric shaft wheel is positioned at the leftmost side, and the ring gear of left inside teething-ring plate is positioned at the leftmost side, at this moment, is meshed with on the right side of external gear on the right side of ring gear.When speed change gear starts, when i.e. eccentric shaft 3 is rotated by input torque, each eccentric wheel drives internal tooth ring plate 4 to move, two internal tooth ring plates 4 are made to conjugate, carry out push-and-pull by the ring gear external gear wheel respectively of two internal tooth ring plates 4, drive the output shaft 1 at external gear and place to rotate, it is achieved deceleration output function.
