SU7199A1 - Adaptation to railway axle boxes for lubricating axle journals - Google Patents

Description

The proposed tool E for rail sleeves for lubricating the necks of the axes is shown in a schematic drawing in which FIG. 1 and 2 depict its vertical sections in two mutually perpendicular planes; FIG. 3, 4 and 5 parts of the brackets of the steel frame in various projections.

A box-like fitting 8 is seated on a normal box carriage having a square neck 12 and secured with four bolts 9 of the lower box ring. The tube 10 is inserted at one end into the hole of the upper part of the housing up to the bearing hole, and the other cut end is screwed into the hole of the stand 5 by rotating the latter in the hole of the liner 7 (Fig. 1 and 2). The stand 5 is fixed in the liner 7 with bolts of the upper ring 6 of the box, after which a reservoir 4 equipped with a piston 3 is screwed into the stand. The piston 3 is inserted into the reservoir 4 after filling the latter with a lubricant, and the reservoir 4 is closed with a lid 1 provided air valves, not shown in the drawing.

As the car moves, the neck of the axle shaft engages the lubricant supplied by the gradual pressure of the piston under the action of its own weight of the latter and continuous jolts at the joints during the movement; the faster the movement of the car, the faster the supply of lubrication.

To measure the movement of the piston, a glass plate is used, inserted into the vertical slot of the reservoir 4 and fastened with a frame equipped with a scale.

A screw (not shown in the drawing), held in its proper position by a spring frame, serves to regulate the lubricant supply.

Pa figs. Figures 3, 4 and 5 show the brackets of the steel frame, which serves to more reliably fix the fitting 8 and the reservoir 4 to the axle box. The frame is made up of a lock 15 (Fig. 3), an arc 16 (Fig. 4) and a bracket 17 (Fig. 5), intended for fastening the arm with the spring of the car using bolted joints.
