Abstract

The invention relates to mechanical engineering and can be used in drives of transport and other machines for automatically varying the speed of rotation of the driven shaft depending on the load on it and allows to increase the reliability and extend the range of transmitted speeds. The locking device is made in the form of a face ratchet wheel 7 fixed on the housing 1 coaxially with the bearing shaft 3 and the pawl 6 mounted on the free end of the elastic plate 4.

Description

I1

The invention relates to mechanical engineering and can be used in drives of transport and other machines for automatically continuously varying the speed of rotation of the driven shaft, depending on the load on it.

The purpose of the invention is to increase reliability and. extending the range of transmitted speeds by performing a locking device in the form of a face ratchet engagement about

Figure 1 shows the proposed transfer; Fig. 2 shows the section A-A in FIG.

The transmission includes a housing 1, in which coaxial cables 2 and driven 3 shafts are installed. Elastic plates

4 one end attached to the hub

5 of the known shaft 3. At the other end of each elastic plate 4, the pawl 6 is fixed, which is designed to interact with the end ratchet wheel 7. The ratchet wheel 7 is rigidly fixed on the housing 1 coaxially to the driven shaft 3. The leash 8 with the roller 9 is rigidly fixed on the drive shaft 2,

The transmission works as follows.

When the drive shaft 2 rotates with the driver 8, the roller 9 engages in, engages with the elastic plate 4 and deforms it to the angle. after which the contact of the roller 9 with the plate 4 is interrupted. Under the action of elasticity, the plate begins to move in the opposite direction, which leads to the closure of his dog 6 on the ratchet wheel 7, and the stored device

25 2

The force of elasticity is applied relative to the body to the driven shaft 3 Roller 9, while continuing to move, engages with the next elastic 1-point 1, after which the plate deformation process is repeated. At the same time, due to the rotation of the driven shaft 3, previously deformed plates 4 give up their potential energy to the driven shaft 3

The greater the angular velocity of rotation of the driven shaft 3, the faster the elastic plates 4 give up the accumulated energy and the smaller their number remains in the deformed state and, therefore, the smaller the total moment of elastic forces is applied to the driven shaft 3.
