Mechanical reduction gear

专利摘要:
The invention relates to mechanical engineering and can be used in robotics, in agricultural machines, in clock mechanisms, in analog display devices, micromechanics, tools and measuring mechanisms, gears, etc. The purpose of the invention is to reduce. dimensions and improved manufacturability. When moving the rotor 12, driven by an eccentric 13 connected to the drive shaft 1, pairs of junction bodies successively interact with all the slots 10 and 11 of the gear units 6 and 7. At the same time, no more than two pairs of moving bodies are coupled with the slots 10, 11, while a third pair is free. Thus, the rotation of the driven shaft 5 is made up of a large number of single steps of a pair of running bodies due to their adhesion with the corresponding pair of grooves, which increases the accuracy, and the gaps resulting from wear do not accumulate. 20 hp f-ly, 29 ill., 2 tab. 15 10 i WITH

The mechanical gearbox contains a drive shaft 1 rotating in two bearings 2 and 3, one of which is housed in the gearbox casing 4, and the other in the hub of the output shaft 5 Be- 50 blowing shaft 1 and the output shaft 5 are coaxial, their angular velocities rotation depends on the gear ratio of the mechanical gearbox (Fig. 1-9). The mechanical gearbox contains two 55 gearbox bodies 6 and 7 which are coaxial with each other to the drive shaft 1. The gear member 6 is the supporting and fixedly connected to the casing 4, the gear member 7 is connected to the output shaft 5 and is the follower. Each of the gear units 6 and 7, respectively, contains an annular crown 8 and 9, they have different sizes and are installed concentrically. Each of the v crowns 8 and 9 contains a series of drive elements, in this case, respectively, formed by the slots 10 and II uniformly distributed around the center of rotation corresponding to the gear unit 6 and 7. In FIG. 1 crown 9 of the driven gear member 7 has eleven grooves 11, while the crown 8 of the support gear member 6 has seven grooves 10.

When the reference gear opra; i 6 is external to the driven gear unit 7, the drive shaft 1 and the driven gear member 7 rotate in the same direction. The rotor 12 rotates in the opposite direction.
The mechanical gearbox may have a driven gear unit 7, covering the support gear unit 6, i.e. external to organ 6 and rotates in the opposite direction to rotation of drive shaft 1 and eccentric 13 (fig. 10-20). The rotor 12 is rotated in the same direction as the driven gear unit 7.
When the directions of rotation of the eccentric 13 and the driven gear organ 7 are opposite, the formula for determining the number of drive elements of the gear bodies is as follows:

40 21 and 22, successively interacting with the grooves 10 and 11, respectively, of the p-bearing organs b and 7. The supporting gearbox b covers the driven gearbox 7.
The mechanical gearbox can have at least one additional rotor 23, driven by the drive shaft I and the eccentric 13. (Fig. 25). Each of the rotors 12 and 23
0 in FIG. 23 has two arms each carrying the main rotor 12, the driving bodies 15 and 16, 17 and 18, the additional rotor 23, the driving bodies 24 and 25, 26 and 27. The rotors 12 and 23 are concentrically mounted with the possibility of angular shift relative to each other by the spring element 28.

Each of the rotors 12 and 23 works by itself, ji this condition is taken into account when calculating the gearbox.

At that moment, when the undercarriage 18 leaves the groove of AND of the supporting gearbox 7 and when the undercarriage 17 leaves the notch 10 of the driven gearbox 6, the undercarriages 15 and 16 enter into the grooves 10 and -1 of the gearboxes 6 and 7, which are located at the previous step of the rotor 12
15 against each other. During the final step, the rotor moves from the position indicated by the solid line to the position indicated by the dotted line. This is achieved due to the instantaneous rotation around the center of the running member 16, trapped in the groove 11. of the supporting reducer member 7. During this turn, only a pair of running members 15 and 16 are in
25 engagement with the gearbox bodies 6 and 7, the undercarriage 16 remains stationary, and its axis serves as the axis of rotation of the rotor 12, while the undercarriage 15 is in engagement
30 with a groove 10 and carries the last of the SRI to the position shown by the bar. The mechanical gearbox works as follows.
During the movements of the rotor, 12 pairs of travel bodies 15–20 consistently interact with all slots 10 and II of gear units 6 and 7. At the same time, no more than two pairs of travel members are engaged with slots 10 and 11, while the third pair is free.
In the embodiment shown in FIG. In 3 states, the eccentric 13 is carried away in the direction of the Research Institute of the arrow f, a pair of travel bodies 15 and 16 penetrates groove 10 and 1 of gear units 6 and 7, while a pair of travel bodies 19 and 20 comes out of grooves 10 and P, and - hooks 17 and 18 of the head out of the slots 10 and I.
When the rotor 12, carried away by the drive shaft I, is transferred from the state shown in FIG. 3, to the state shown in FIG. 4, it simultaneously rotates around the running gear 13, trapped in the groove 10 of the support gear member 6 in which it is located. Such an instantaneous turn leads to the movement of the groove 11 of the driven gear member seized by the driving member 16 in the direction of the arrow g. During the said movement of the rotor 12, the pair of the traveling bodies 19 and 20 discharges from the slots 10 and 11, and at the end of the movement or pitch of the rotor 12, the pair moves 35 10 when it is positioned at the point 15, 10. At this point in time, a certain groove 10 slave
gearbox body goes into the polo
against some groove 11 of the gearbox 7.
The bodies 17 and 18 enter into the grooves IO and 11 at the moment when the running bodies 15 and 16 leave the grooves 10 and 11 interacting with them.
During such a single movement or rotor pitch, the angular variation of the driven gear unit 7 in this example is 1/77 revolution.
The drive shaft I must make two full turns in order for the other of the arms 14 of the rotor 12 to return to the state shown in FIG. 3
From the states of the respective slots 10 and P in FIG. 3 and 9 it can be seen that the driven gear unit 7 made 1/11 of its turnover in seven consecutive steps.
