FIG. 1 shows a washing and spinning machine; general view; in fig. 2 and 3 are diagrams of the formation of the working gap h; in fig. 4 is a section A-A in FIG. one; in fig. 5 is a section BB in FIG. four.

The washing and spinning machine contains an inner drum 1, balancing pockets 2, a horizontal shaft 3, a floating bearing support 4, an outer drum 5 and attached to it. butt means automatic tune-up, which contains a vertical guide 6, a slide 7, a displacement sensor 8 with a spring-loaded rod 9 coming into contact with the moving part of the floating bearing support 4 of the inner drum 1, a relay-interrupter 10, a stepper motor 11, with a lead screw 12, articulated with a sled 7.

On the slide 7 and on the horizontal hall 3 of the inner drum 1, an oscillation sensor of the inner drum is mounted, comprising a stepped sleeve 13, a bearing support 14, a clip 15 with inclined slots 16, a disk 17 with a hub 18, a transition sleeve 19, valves 20 and two shoulders 21, hinged on the disk 17, whose short arms come into contact with the inclined slots 16 of the sleeve 15, and the long shoulders with the valves 20.

The automatic adjustment tool and the vibration sensor together with the valves 20, the channel system and the pump 22 form the balancing pockets control system, which serves to balance the inner drum 1 regardless of the amount of its movements in the vertical plane on the floating bearing supports 4. Additionally squeezing machine introduced guide 23 and radial rods 24 mounted on the disk 17 and spring-loaded springs 25 to the grooves 26, made in the holder 15 and located m I am waiting for two shoulders levers 21. Moreover, the rods 24 are pressed by the springs 25 to the grooves 26 of the yoke 15 to equalize the mass of the disk 17 with structural elements fixed to it relative to the floating bearing support 4. Additionally specified elements introduced into the machine, structures together with the automatic adjustment tool and with elements of the vibration oscillation sensor form a balancing device operating in automatic mode.

In addition, the additionally introduced structural elements, as well as the bearing support 14, the sleeve 15 with the grooves 26, the guides 23, the rods 24 spring loaded 25 to the grooves 26 of the sleeve 15, together represent an additional floating bearing support that in the automatic mode releases the floating bearing SUPPORT 4 from the action of dynamic forces, occurring in circular, oscillations of the disk 17 with structural elements fixed on it.

The automatic adjustment tool serves to maintain the required size of the working gap h (see Fig. 2), a change in which in the direction of increasing would lead to a decrease in the balancing accuracy of the inner drum 1.

The increase in the specified working gap h is a consequence of the release of moisture from the material being pressed.

The interaction of the automatic adjustment means with additionally introduced structural elements (see Fig. 4 and Fig. 5) ensures that the unbalanced parts of the vibration sensor are balanced in the automatic mode.

Washing-spinning machine works as follows.

The tool automatically adjusts monitors the movement of the disk 17 of the oscillation sensor of the inner drum 1 in a vertical plane, and, thus, the optimum value of the working gap h. The upward movement of the inner drum 1 and the disk 17 on the floating bearing supports 4 is characterized by an increase in the working gap h. In this connection, the movable part of the floating bearing bearing 4 acts on the spring-loaded rod 9 of the displacement sensor 8, the relative length of which decreases in proportion to the increase in the working gap h. The displacement sensor 8 is activated when moving

its spring-loaded rod 9 and using the relay-chopper 10 gives the stepping motor 11 a corresponding number of pulsed electric commands and the latter turns the lead screw 12 at a certain angle. The slide 7 of the vertical guide B moves upward by a certain pitch, and together with it the displacement sensor 8 and the step sleeve 13 with the bearing support 14 and the sleeve 15 move upwards behind the disk 17, moves, the necessary working clearance h and the adjusted tension of the springs 25 are restored spring-loaded rods 24, but already relatively new to the position of the disk 17. and this ensures in the automatic mode the balancing of the structural elements of the vibration sensor relative to the floating bearing support 4 drum 1i

The spring stiffness of the additional bearing support is many times less than the spring tension of the bearing bearing support 4. For this reason, the effect of the torque from the mass of the vibration sensor has little effect on the oscillation of the inner drum 1, which has many times more than it has a disk mass of 17 with structural elements placed on it. As a consequence, the additional floating bearing bearing, moved in automatic mode, will only prevent the increase in circular oscillations of the disk 17 from its own action on it. centrifugal inertial forces caused by circular oscillations of its axis of rotation around the geometric axis of the outer drum 1. This significantly reduces the effect of additional inertia forces on the floating subtype support 4 during periods of eliminating imbalance of the inner drum 1, and after elimination the inertial forces disappear altogether .

Additional floating bearing to reduce to a large extent the effect of the inertial moment

on the floating bearing support. contributes to an increase in the spin-separation factor of the washing-pressing machine, for example, mounted in the caravan body of a sanitary engineering station, intended to eliminate epidemics, infections, etc., which have arisen in the uninhabited areas of the country.
