Description

The invention relates to drives with infinitely variable rotational speed and torque of the driven member, in particular to drives of vehicles, tools, and the like.

The purpose of the invention is to increase the reliability and expand the range of regulation.

FIG. 1 shows the inertial impulse mechanism, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - mechanism, embodiment.

The inertial impulse mechanism (Fig. 1) consists of the housing 1, in which the bearings 2 and the driven 3 shafts are mounted on the bearings. On the drive shaft 2, on the hinge 4, there is installed a sleeve 5 with a ring 6 freely rotating on it with weights 7 mounted on it. On the driven shaft 3 a rotor 8 is rigidly mounted or made as a single part, in which guide grooves 9 are made that have a curved surface. To change the angle of the sleeve 5, a device is used in which a drive ring 11 with a bearing and an outer ring 12 with studs 13 are inserted into the slots of the plug on the drive shaft 2 on the key 10.

14. Ring 11 and sleeve 5 are connected by an earring.

15. The fork 14 may be connected, for example, with a lever for manually setting the angle of the sleeve 5 or with an automatic torque control mechanism (not shown) depending on the load by changing the angle of the sleeve 5.

OE CO 00 N5 00

The inertial mechanism works as follows.

When the angle of the sleeve 5 is set to zero (), the drive shaft 2 rotates idle, the ring 6 and the weights 1 are fixed, which corresponds to the neutral position of the driven shaft when the torque on it is 0. When the fork 14 rotates, the ring 11 moves along the axis of the drive shaft 2 key 10, and shackle 15 deflects sleeve 5 at some angle. In this case, the ring 6 and the weights 7 begin to oscillate in the plane of the axis of the drive shaft 2 with a frequency equal to the frequency of rotation of the drive shaft. The presence of the tilt angle of the sleeve 5 predetermines the occurrence of a tangential force that tends to turn the ring 6 together with the loads 7 in the direction of rotation of the drive shaft 2, which prevents the curvilinearly made surface of the curved groove 9 Consider (Fig. 2) the movement of the load 7 from one extreme position (point A) to the other extreme position (point B) Moving along the curvilinear surface of the curvilinear groove 9 to the point "O, the load 7 moves with acceleration, and the curvilinear surface of the groove 9 allows the load 7 to turn for some the angle in the direction of rotation of the drive shaft, which is expressed by the displacement of goods 7 on

h value

At point 0, weights have maximum kinetic energy. From point 0, the surface of the groove 9 tends to change the trajectory of the loads 7 and rotate them at a certain angle in the direction opposite to the rotation of the drive shaft 2, which is prevented by the inertia forces of the loads 7. As a result, the pressure from the inertia forces of the loads 7 is transmitted to the walls of the grooves 9, aspire

move the rotor 8 with the driven shaft 3 from the path of movement of the loads 7 In this case, if the force of the inertia forces of the loads 7 is exceeded, the guide grooves 9 are above the load applied to the driven shaft 3,

the last one turns on some

angle in the direction of rotation of the drive shaft 2.

When the movement of goods from point B to point A

a similar phenomenon occurs.

When the load on the driven shaft decreases, the adjustment mechanism increases the angle of inclination of the sleeve 5, and therefore, the amplitude of oscillation of loads 7 increases. But, since the frequency of oscillations of loads 7 depends on the difference between the frequencies of rotation of the drive 2 and the driven 3 shafts, with increasing frequency of rotation of the driven shaft 3 the frequency of oscillations of the loads 7 decreases, and consequently, the speed of their movement, their kinetic energy and pressure forces on the slots 9, i.e. reduced torque on the driven shaft 3 with a simultaneous increase in the frequency of its rotation

On the driven shaft 3, the rotor 16 is rigidly fixed, in which along the perpendicular axis of the drive shaft 2 and the sleeve 5 passing through the center of rotation axis, tides 17 are made, in which rods 18 with ball joints 19 are fixed, and on the other side the hinges 19 are connected with weights 7 (FIG. 3) This connection of loads 7 with the driven shaft 3 by means of rods 18 creates conditions for the movement of loads 7 (when they oscillate) along an arc of radius equal to the length of the rod 18 between the centers of the ball joints 19, identical to the first variant, due to What 35 mezanizm action second onstruktivnogo embodiment remains the same mechanism of action of the first constructive option.
