SU85955A1 - Mechanism to turn the draw drum on and off - Google Patents

Description

The invention relates to the tina of known mechanisms for activating a drawing drum by means of a conical clutch acting on a spring-loaded fricnion clutch and alternating against pressing neio are springed by means of a rod iodine along the axis of the drum.

The proposed mechanism is characterized in that in order to achieve a smooth inclusion in the axial bore of a conical friccia, a sleeve is installed, the upper end of the collar of which is located between the active spring / bale and the hydraulic front.

The lower collar of the sleeve protrudes from the frictio and is iodized by the action of the rod, during axial movement of which the spring is initially compressed and then the spring rises.

To automatically stop the drum when the friction clutch is turned off, a brake is applied, acting simultaneously with the axial axle shaft.

FIG. 1 depicts a 151111-sectional section of a mechanism; on fng. -2- modification of the proposed mechanism.

In the axial hole of the stalk / conical clutch, a sleeve 2 is fitted, fitted with a flange 3. The latter is located between the friction clutch of the 4 and the slider. 1- nzhnn1 | the end of the sleeve 2 p. stands out of the stunts of the cup / and is iodized by the impact of the node 1: ik 5, siabzhetpyugo top fork.

By turning the handwheel 6, sitting on the roller 7, and the two shchetseps, the eccentric 9 is rotated, which moves the lift 5 in the ocei.OiM direction.

The fork of the hoist 5 initially (when P1 is turned off) lifts the sleeve 2 by the amount of the gap between the plug of the butt-lifter 5 and the end of the hub cap /, which initially compress the spring 4, then the cup / starts to rise, which moves away from the clutch 10 and gives the opportunity the turns of the leites // move away from the outer cylindrical surface of the coupling 10, which makes it 1 and 1;

When turning the handwheel 6 backwards, the sleeve 2 must be mounted simultaneously with the cup /. This simultaneous movement of nx downwards in the far distance is limited, since the cup / oterestactor in the socket of the coupling 10 and the corresponding frictional force for the predvaritel1, the noise of the upper turn of the tape //. The next one is not forks of plug 5 and plug-in-2 to create additional conditions, press the cup with a spring 4, adjustable nut / L of the pin 14, fixed in the sleeve 2.

Such a double inclusion system creates the required main tune of the drum 12.

At the same time, the brakes are turned on automatically and the brakes are turned 15 with a fixed cam 16 mounted on the roller 7. In order to unwrap the upper turn of the tape from inertial forces, it is on) when the device turns on the inertia of the inertial forces, it is on the device when the device turns on the inertia of the inertial forces, when the device turns on the inertia of the inertial forces, it is on the device when the device turns on the inertia of the inertial forces in which the finger 18, which is skrenleiiy with a cup, moves freely.

The modification of the mechanism is shown in phi 2 and consists in the fact that instead of spring 4 and sleeve 2, a plate 19 is used, provided with iodine influence 5a of the ends 19a of a greater length than the edge of panel 1a to enable activation of the start of the cup 1a by the force of its weight and then the load of the cup with the weight of the lowered plate 19, switching off first, the plate 19 is first lifted, and then tea 1a is removed from the landing cone.

A cup of conical friction clutch and a hydraulic shock absorber to increase the smoothness of the key drum.

Claims (2)

1.Mechanism for switching on and switching off the draw baraba by means of a conical frnccioia acting on a spring frame ;; is a clutch that is moved opposite the spring by means of an elevator movable along the axis of the barabia, characterized in that, in order to achieve a smooth operation of the mechanism, in axial direction The opening of the cup of the conical clutch is freely placed in the bushing, the upper end of which has a shoulder, is located between the friction clutch spring and the cup of the frykion, and the lower end is drawn out of the cup of the friction clutch It is iodized by the action of the lift, intended for its axial movement during firing, to put the friction pulley into action, first by its own weight, and then pressurize the springs on it, while at the same time unplug the spring from the friction cup, and then remove The last of the engagement with the clutch gland element. 2. The mechanism of mechanism change according to claim 1, characterized in that the springs and bushings are applied coaxially to the plate and thickened with concentrically relative to each other bent edges, exposed by the lift, to enable the cup to be activated first by its weight and then already by the force of loading the weight of the disc produced, when turned off
