SU20033A1 - A device for turning wheel pairs when re-tightening weakened tires for the purpose of uniformly heating the latter - Google Patents

Description

When loosening the bandage on the train chute, they resort to dragging it. If the bandage is slightly weakened, and the bandage is still sufficiently thick, the bandage is transferred as follows: after heating, the bandage is removed from the rim, heated to a dark red face and then put on the rim again. When the bandage is cooled, its diameter decreases, and the outer circumference decreases by less than the inner diameter and the thickness of the bandage becomes somewhat larger.

With a more significant weakening of the bandage on the rim, it is necessary to resort to the setting between the rim and the bandage of the roofing gland.

The proposed fixture is designed to reduce labor costs and facilitate the above activities.

In FIG. 1 is a front view of the device; FIG. 2 - view from above; FIG. 3 and 4 are devices for hanging wheel sets in two projections.

The device consists of a base-C, from which, with the aid of bolts a, bed B is strengthened, with a height-adjustable board A. The board A is mounted on shaft L, on which roller L is mounted, with a grooved surface and gear wheel l, as well as another shaft M, with a gear wheel l, and flywheels m (Fig. 1). When the ramp is rolled up to the device, the bracket L is removed from the bolt B of the suspensions P, (FIGS. 3 and 4), then taliskat is mounted on the roller supports fJ, after which the bracket is put back in place. The ramp bandage is clamped by means of the handwheel, between the roller cutter and the roller o (for elasticity there is a spring 3).

Rotation of the flywheel .h results in rotation of the ramp for uniform heating of the tire. In order to be able to transfer bandages on wheels of different diameters in frame B and in the detachable part (board) A, there are openings that make it possible to vary the height of the shaft D, and accordingly the height of the spring-roller clamp, o.

In view of the need for stopping the ramp at certain sites of the bandage for continuous heating, the device has a brake consisting of a lever connected to a retractable rod p, at the end of which a wooden block 7 is attached to the sticking ramp. You can use the agglomerated instrument: 1) to retract bandages and without opening the slopes from under the locomotive. The subject of the patent. 1. A device for turning wheel pairs when re-tightening the weakened Mx of tires, for the purpose of uniform heating of the latter, characterized by the use of a spring-roller clip o, located on the adjustable bed, for which the roller rotated by hand by means of a gear transmission, rotates the wheel pair and has a grooved surface for better adhesion to the tire and wheel rim. - 2.: The design of the device described in paragraph 1 is different from 1 to 1, and with the fact that the cogs for the roller and the gear, as well as the spring arm for the roller, are arranged, in order to use the gear for wheelsets with wheels of different diameters, the height attached to the bed, the board A. 3. Application to the one described in Sec. 1 and 2 to the fixture, in order to jam the wheels when they are stopped, the brake shoulder T located on the retractable rod. 4. Application to the device described in par. 1 and 2, in order to enlighten wheelsets, pumped out from under the vehicle, suspensions П with roller supports for the axis of the wheelset.
