SU1538011A1 - Pneumatic vibrator - Google Patents

Abstract

The invention makes it possible to reduce energy consumption and increase work efficiency. When gas is supplied under pressure to pipe 5 through tangential holes 6 in the pipe, gas flows directly onto ball 3 and causes it to rotate along groove 2 made in sleeve 1. The oscillations caused by the ball rotation are transmitted to waveguide 4. The ball rotates , rotates the sleeve 7 connected with it through the stem 8 with a slot. In this case, the sleeve 7 blocks all the holes 6 except one, from which the gas stream is directed. Thus, the sleeve with a slot provides a reduction in unproductive gas losses, contributes to an increase in the frequency and amplitude of the vibrations generated by the vibrator. 2 Il.

Description

31

The invention relates to devices for producing mechanical vibrations.

The purpose of the invention is to reduce energy consumption and increase efficiency.

Figure 1 shows a diagram of the vibrator; figure 2 - section aa in figure 1.

The pneumatic vibrator comprises a sleeve 1 with an inner annular groove 2 rolled by ball 3, a waveguide 4 and a nozzle 5 for supplying compressed gas (air) with tangential openings 6 for the gas to exit, made of a material with a low coefficient of friction, for example Teflon or Teflon, sleeve with a slot. The sleeve 7 is mounted on the nozzle 5 with the possibility of rotation around the axis of the nozzle and connected by a rod 8 with the ball 3.

The vibrator works as follows.

Gas under pressure of 2-5-10 N / m is supplied to the pipe 5, through the tangential holes 6 in the wall of the pipe 5 enters the annular cavity between the pipe and the groove of the holder 1 and goes into the atmosphere. The gas stream coming out of the holes exerts pressure on the ball 3, driving it in a circular motion along the annular groove 2. The ball rotates the sleeve 7, while

the sleeve closes all the holes in the nozzle except for one, which is directly aimed at the ball at the moment. In this way, unproductive gas losses are reduced, the speed of rotation of the ball and the amplitude of vibrations excited by the vibrator increase.

Claims (1)

Invention Formula A pneumatic vibrator containing a yoke with an internal annular groove around the ball, a waveguide rigidly connected to one of the ends of the yoke, a nozzle with tangential openings for supplying gas to the ball, characterized in that, in order to reduce energy consumption and increase operational efficiency, it is equipped with a rod and a cylindrical sleeve with a slot made along the generatrix of the cylinder, wherein the sleeve encompasses the nozzle and is mounted thereon with the possibility of rotation around the axis of the nozzle, while the notch of the sleeve is placed from ositelno nozzle openings to periodically their opening during the rotation of the sleeve, the rod with one end is coupled with a ball and the other - with the hub for transmitting movement of the ball on the sleeve.
