SU34593A1 - Car axle box with automatic lubrication - Google Patents

Description

For the purpose of automatic lubricant supply, the proposed car axle is made with two chambers, the upper one filled with lubricant, an airtight chamber, connected by channels with a groove in the bearing above the axis of the axle, and the other 5 has a connection with the atmosphere and the bottom. part of the box where both chambers are interconnected by a channel with a tube, the end of which is the edge, enters the lubricant poured at the bottom of the lower chamber.

In the schematic drawing of FIG. 1 shows a front view of an proposed axle box; FIG. 2-complete section see rto line AB and partial along the line CD.

From the hermetic chamber A arranged in the upper part of the axle box, fitted at the top with a tightly screwed in stopper 7, channels 2 and 22 pass through the body of the axle box, of which channel 22 ends in a cone-shaped seat, mounted on an asbestos oil-wetted gasket on the cone-shaped, bearing projection 24 9, in which a protrusion passes a channel 20, which passes into a groove c, smoothly converging to the rubbing surface of the neck axis. Channel 2 ends in socket 3, where nut 4 is tightly screwed, with tube 2 inserted into it, passing through a wooden plug inserted into a funnel-shaped hole in the outer wall of the chamber

(379)

And almost dropped to the bottom of the last. Mentioned chamber c is poured into the bottom of the box, has a hole at the top, closed by a lid 7, connected with an eyelet b, screwed into the box, and provided with shoulders 9 and a thickening 8, which serves to increase the weight of the lid in order to prevent bouncing of the lid during movement wagon. At the bottom of the chamber there is a tide with a cutted BHyfpH thread, which is screwed with J4 and square tail / 5 plug 7 / with a hole 72 in the form of a slit for removing from the chamber into the lubricant when the plug 77 is not fully turned out. In addition, the chamber has access to the atmosphere , and also in the lower part of d box through the hole JO. The ears of the bottom of the axle box are reinforced by ribs 23f; otherwise, the axle box may have a device similar to the existing ones.

Before sending the car, lifting the lid 7, pour the chamber into the lubricant until the bottom of the tube 2 is flooded, then unscrew the plug 7, fill the chamber with the lubricant up to the top, so that the lubricant passes through channel 2, and quickly plug the plug 7, place, with part of the lubricant leaves chamber a, but the channel with tube 2 will be filled with lubricant. When a car moves, it enters from chamber a through channels 22 vi 20 into the groove with

lubricant, sticking to the rubbing surface of the cervix, will be carried away to the bottom

part d of the axle box, causing this loss of lubricant from chamber a, resulting in a vacuum in the latter, due to which lubricant will flow into chamber a and chamber into the channel with tube 2. Lubricant flowing down to the lower part i of the axle box level up, it will pour over hole 10 back into the chamber. According to the author, it follows from the above that when the car moves, the lubricant continuously moves from the chamber to the tube and channel 2 to the chamber a, then to

gang axis and back to the camera Vit. d., and when the car stops, the lubricant will be located in nojioe.

Observation of the correct action of the automatic lubricant supply is monitored through the cover 7, and with the correct action the level of lubricant in the chamber should be slightly

higher traffic jams //. If the level of lubricant in the chamber is raised to hole 10, which indicates a malfunction in the lubricant supply, since the volume of the chamber s is calculated in such a way that all the grease coming out of the chamber and does not reach the opening 10, then remove the plug 7 / and releasing the lubricant from chambers in, fill the chamber and with lubricant, which should be enough for several spans.

The subject matter of the invention.

A car axle, characterized in application, for the purpose of automatically supplying a lubricant, grease-filled hermetic chamber a, connecting channels 22, 20 with a groove c in a bearing on the axle neck, and channel and tube 2 having access to the atmosphere and the lower part d cups camera in, with the end of the tube 2 is lowered into the lubricant poured at the bottom of the camera.
