Description

I

FIELD OF THE INVENTION The invention relates to railway transport and concerns the design of the lubricants of the wheel-motor units of locomotives.

A device for lubricating motor axle bearings and a locomotive traction gear is known, comprising a motor axle bearings housing mounted on an axle of a pair of wheels, divided into two tanks and two working chambers equipped with exhaust oil discharge channels from them, and a gear housing 1 . -, „-.

A disadvantage of this device is the complexity, the design, and the need to separate the engine with axle bearings and a traction gear with separate lubricants.

The invention is a simplified design of the device.

For this oil, the bath of the casing of the radiator at the level of immersion of the crown gear drive gear is communicated with the discharge channels of used oil from the working chambers of the motor-axial bearings, and in the upper part of the casing of the gearbox there is an oil receiver connected to oil level in them.

FIG. 1 shows a diagram of a device for lubricating motor axle bearings and traction gear; in fig. 2 - a section through the working chamber; in fig. 3 - a section through the capacitive chambers.

The housing 1 of the device is made as one unit for two motor-axial bearings 2. Its internal volume is divided into two working chambers 3, interconnected by capacity 4 through windows 5. Capacity 4 has a sump 6 with drain plug 7. Under capacity 4 at the level of oil Noah bath 8 gearbox housing 9 is located capacity 10, connected to the channels and discharge of used oil from the bearings 2. Bath

5 8 through the channel 12 and the tank 10 communicates with the channel 11 of the discharge of oil. The container 10 by the channel 13 through the window 14, located at the level of the windows 15 (see Fig. 1) from the chambers 3 in the cavity of the motor-axial bearings, connect 2Q dinene with a capacity of 4. Through the windows 15 to the axis of the pair of wheels 16 brings the wick 17 from the polster device 18 installed in the chamber 3. In the gearbox housing 9 above the chambers 3, an oil receiver 19 is installed, connected to the chambers 3 by a channel 20 through the container 4.

In the lower part of the gear housing in the bath 8, the flaps 21 are radially mounted, guiding the oil splashed by the gear wheel 22 into the oil receiver 19,

In the container 4, an opening 23 is made for pouring oil, which is closed by a stopper 24, the CAPACITY 10 has a sump 25 with an excessive stopper 26..

The housing 1 is equipped with a bolt, in 27 with washers 28 it is fastened to the skeleton of the electric motor 29, the gearbox housing 9 is made detachable from two halves and fixed to the frame of the electric motor 29 by bolts 30 at three points, the Chambers 3 are covered with covers 31 attached to the body 1 device with bolts 3i,

During the refueling of the system, the oil is smacked into the opening 23 of the tank 4, t of the tank 4 through the windows S, it enters the i chamber 3, from the chambers 3 through the channels 1 and the capacity 10 i the bath 8 of the gearbox housing 9, filling the system goes to the oil tank § § tia-ped control gfobku 33 i gearbox housing, 9 spaced on the level necessary for the normal operation of the gear, t, e, at the level of the outer circle. ring gear, rut w. A stopper 34- is provided for draining the oil from the ra card.

When the traction gearbox is operating, the oil that is sprayed with the sprocket wheel ii, p0 pagdagt SHIELDS il and send them

into the oil receiver 19, then through channel 20 into tank 4 and chambers 3, and from chambers 3 through channels 11 into tank 10 and bath 8. Thus, a single circulation lubrication system for motor axial bearings and a thrust transmission is obtained.
