Embodiment approach 1

[0030] figure 1 It is an embodiment of the present invention. The structure of the device is as follows: a transmission chain is formed by a shock wave device, a swing movable tooth, a movable tooth carrier and an internal gear 5 . The two-phase cam 2 and the input shaft 1 are fixedly connected through a key 10 to form a shock wave. The right end of the input shaft 1 is supported on the right end cover 12 by a ball bearing 11 , and the left end is supported on the output disk 7 by a ball bearing 13 . The left end of the output shaft 9 is supported on the frame 15 with the ball bearing 14, and the right end is firmly connected with the output disk 7. Movable rack is made of output disc 7, floating disc 8 and pin shaft 6. The output disc 7 and the floating disc 8 are fixedly connected as a whole by pin shafts 6 uniformly arranged along the circumferential direction. The oscillating movable tooth is composed of a movable tooth base 3 and two needle bearings 4 . The large-di...

Embodiment approach 2

[0033] Figure 7 is another embodiment of the present invention. The structure and working principle of the device are as follows: two double-phase cams 2 with the same structure are staggered by 90° and fixedly connected with the input shaft 1 to form a shock wave. Movable rack is made of output disc 7, floating disc 8, separating disc 16, pin shaft 6 and pin shaft sleeve 18 sleeved on the pin shaft 6. The output disc 7 , the floating disc 8 and the partition disc 16 are fixedly connected as a whole by the pin shafts 6 and the pin shaft sleeves 18 uniformly arranged along the circumferential direction. The position between the output disk 7 , the floating disk 8 and the separation disk 16 is guaranteed by the pin shaft sleeve 18 . Two rows of swing teeth with the same structure and composition as the first embodiment are arranged on both sides of the partition plate 16 . Two rows of movable teeth on the same pin shaft are arranged staggered by 180° around the pin axis. In...

Embodiment approach 3

[0035] Figure 8 It is yet another embodiment of the present invention. The components and transmission principle that make up the device are the same as those in Embodiment 2; the difference between the two is that the angular positions of the two dual-phase cams 2 in Embodiment 3 are the same, the angular positions of the two rows of swinging movable teeth are the same, and the two The angular position of the internal gear 5 is also the same.

Abstract

A kind of the biphase wabbler shock oscillating tooth actuating device, it includes the shock implement,the jigging oscillating tooth, the oscillating tooth carrier and the internal gear; the jigging oscillating tooth is composed with the oscillating tooth matrix and the multi roll bearing, the oscillating tooth carrier is composed with the output panel,floating panel which is joint with the output axis and the pin arbor whose double end joint with each other; The jigging oscillating tooth lies between the shock implement and the internal gear, its character is: the shock implement is composed with the input axis and the biphase wabbler, the profile of the biphase wabbler is a standard geometric axis symmetric line, the biphase wabbler joint with the input axis unbiased. When the biphase wabbler tours along with the input axis, the biphase wabbler rolling contacts with the intermediate section of the oscillating tooth matrix, to drive it roll around the oscillating tooth matrix, and fulfills the multi roll bearing of the both sides of the oscillating tooth matrix rolling contacts with the internal gear simultaneously, so the jigging oscillating tooth impulses the oscillating tooth carrier toured, and completes the pass of the motion and the impetus.

Description

technical field [0001] The invention relates to a two-phase cam shock wave swing movable tooth planetary transmission device with less tooth difference, which is used to realize the motion and power transmission between two shafts, and belongs to the technical field of mechanical transmission. Background technique [0002] According to its transmission principle and structural composition, movable tooth transmission can be mainly divided into push rod movable tooth transmission, roller movable tooth transmission and swing movable tooth transmission. Among them, the significant difference between the swing movable tooth transmission and the push rod movable tooth transmission and the roller movable tooth transmission is that the movable tooth that slides under the force in the movable tooth groove is changed to the swing movable tooth that rotates around the pin shaft on the movable tooth frame. . The outstanding advantage of the swing movable tooth transmission is that it o...
