Abstract

The invention relates to mechanical engineering and is intended for use in adjustable hydraulic couplings of heavy duty machines. The purpose of the invention is to increase the service life by increasing wear resistance and improving performance by increasing the transmitted power. The hydraulic coupling comprises a housing (K) 1 rigidly connected to the drive shaft with a hydraulic cavity 3. In cavity 3 there is an elliptical rotor (P) 4 rigidly connected to the output shaft. A flexible ring (BK) 6 in the form of an endless roller chain is mounted on the P 4 with the possibility of sliding. In the cylindrical cavity K 1, pistons 9 are located, connected to GK 6 by means of rods 11. A cork regulator 18 with openings is installed in the channel P 4. Cavities 8 and 3 communicate freely with each other. When rotating, K 1 and the inhibited P 4 GK 6 rolls around the elliptical surface of P 4. The pistons 9 reciprocate. With this, the openings 3 of the regulator 18 are connected to the cavity 3, the fluid circulates freely. The overlapping of the channels of the regulator 18 draws P 4 into rotation with K 1 and the torque is transmitted to the output shaft. 2 Il.

Description

This invention relates to a magnaine structure and is intended for use in a heavy-duty machined magnet.

The aim of the invention is to increase the service life by increasing wear resistance and improving operational performance by increasing the transmitted power.

The adjustable hydraulic coupling includes a housing I, rigidly connected to the drive shaft 2 and having a hydraulic cavity 3 in which the rotor 4 of the ellipse form is placed. Rotor A is fixed to the upper shaft 5. On the rotor A it is installed with the possibility of sliding a flexible ring 6 which can be made, for example, in the form of an endless roller chain. On the housing 1 there are two tides 7 in which,

in the diagonal direction there are cylindrical cavities 8 with pistons 9, and with sealing rings 10. Pistons 9 are connected to flexible ring 6 by means of rods 11, located diametrically relative to cavity 3 and connected to this ring 6 by means of pins 12. At that, rods I1 rest on rollers 13 .. Rotor A has an axial channel 1A connected to a cavity with 3 channels 15 and 1.6, and with over cavities - channels 17. Channel 1A is equipped with a cork adjuster 18 with a version of 19 and a draft of 20 control. Cavities 8 and 3 communicate freely in the piston zone.

Adjustable hydraulic coupling works as follows.

When the housing 1 rotates and the rotor A is rotated, the roller-chain chain 6 is wrapped around the elliptical surface of the rotor A and the piston

nor 9 reciprocate. Such a free rotation of the housing on the rotor A is possible only with full alignment of the openings 19 of the regulators 18 with the channels 15. At the same time, the fluid circulates alternately on both sides alternately between the piston and sub-piston cavities 8 and the rotor A, connected to the output shaft 5, remains motionless. The torque is not transmitted to the shaft 5. The gradual overlapping of the channels 15 by the walls of the regulator 18 draws the rotor A into rotation together with the housing 1, as a result of which the clutch begins to transmit a steep torque to the shaft 5.
