Description

The invention relates to devices for supplying lubricant to slide bearings, in particular to locomotive motor-axial bearings.

The purpose of the invention is to increase the reliability of operation.

The drawing shows the device, the overall view in section.

The device includes a working chamber 1 and a filling chamber 2 located in the housing 3 and separated by a U-shaped partition 4.

The tube 5 is installed between the upper part of the box body 3 and the partition 4, connecting the working chamber 1 to the atmosphere with its upper end. The lower end of the tube 5 is attached to the partition 4.

An air tube 6 is installed in the partition 4, connecting the working chamber 1 with the filling chamber 2.

In the tube 5, the oil filler tube 7 is installed and sealed relative to it with a stopper 8 at its lower end. The opening 9 in the partition 4 communicates the working chamber 1 and the filling chamber 2.

In the wall of the lower end of the tube 5 placed in the working chamber between the branches of the partition 4, a calibrated opening 10 is made. Above this, also in the area of the working chamber, a similar additional calibrated hole 11 is made, the diameter of which is determined empirically.

The partition 4 of the working chamber is in contact with the wick 12.

In the tube 8 of the tube 7 is made through the channel coaxially with the hole 9 of the partition 4.

The operation of the device is as follows.

The oil is filled into the axle box with the help of the oil filling stub 7, which is inserted through the tube 5, and the opening 9 in the partition 4, which connects the working 1 and the filling 2 chambers, is joined to the through channel in the plug 8.

Turn on the oil pump. The plug 8 of the oil filling tube 7 closes the opening 10. The oil under pressure through the oil filling tube 7 enters the opening 9, filling the filling chamber 2, then fills the working chamber 1.

The air from the filling chamber 2 escapes through the air tube 6 into the working chamber 1 and through the gap between the tubes 5 and 7 into the atmosphere.

After the filling of the working chamber 1 with oil, the upper calibrated opening 11 located above the oil level (indicated by dotted lines) is closed and the air discharge is stopped.

The control of the end of the axle filling is done by stopping the release of air from the oil filling tube 7, which can be equipped with a whistle (not shown), like the whistle of a domestic dike.

The device provides an absolute guarantee of filling the working chamber with lubricant, which eliminates the work of the wick of the 12 axle box without lubrication and ultimately increases the reliability and service life of the entire device.

Claims (1)

Invention Formula A device for filling with lubricant of a two-chamber container of a axial bearing axle box containing a partition with an opening placed in a container divided into a filling and working chamber, a tube whose upper end is located in the filling chamber and communicates with the atmosphere, and the lower one is attached to the partition and in the zone This end has a calibrated opening in the wall of the tube, an oil filling tube in the specified tube, a stopper at the lower end of the tube for blocking the hole, and an air pipe, one end to The second is located in the upper part of the filling chamber, and the other communicates with the working chamber, characterized in that, in order to increase the reliability of operation, the partition is U-shaped, with its parallel branches oriented across the vessel and the specified opening is made in them, the lower end of the tube located between these branches in the working chamber, an additional calibrated hole is made in the tube wall above the indicated hole, and a through channel is made in the stopper, coaxial with the hole in the lower branch of the partition, for feeding and lubricant in the filling chamber.
