Abstract

The invention relates to mechanical engineering and is intended for laying antifriction self-lubricating material into a bearing. The purpose of the invention is to improve the quality of the filling of bearings with antifriction self-lubricating material. The device comprises a lower plate 22 and an upper plate 19 between which a fill bearing is installed. The top plate is joined to the flange 11 of the lubricant injection means. The docking mechanism is made in the form of fingers 20, support bars 18 and drive sliders 21. The slide blocks 21 have upper and lower longitudinal guides housed in mating grooves of the upper plate and bars. The horizontal movement of the sliders 21 provides for the vertical movement of the support bars 18 along the fingers 20. The support bars 18 are connected to the flange 11 of the lubricant injection means. This ensures the coupling of the lubricant injection means and the upper plate of the device, which prevents lubricant from flowing onto the surface of the upper plate and leads to high-quality filling of the bearings. 2 hp f-ly, 4 ill.

The invention relates to mechanical engineering and can be used in the manufacture of bearings, in particular for laying antifriction self-lubricating material.

The purpose of the invention is to improve the quality of the filling by improving the sealing between the material injection means and the top plate.

Figure 1 shows the kinematic diagram of the device; figure 2 - section aa in figure 1; on fig.Z - the device in the working position; on figa - section bb in fig.Z.

The device for filling the bearings with antifriction material contains three mixers 1, each of which is placed in the container 2 and connected with its cover 3 with the possibility of relative rotation and removal with it from the container. The shaft 4 with the stirrer 1 is connected with the drive 5 of its rotation through gears 6-8, the shaft 9 and the quick-release clutch 10 axially spring-loaded mounted on it 10. The containers 2 are fixed on the flanges 11 mounted on the plate 12 with the possibility of free movement along its grooves 13. The position of the plate 12 in the vertical direction is regulated by means of a screw 14. In the central part of each of the flanges there is an opening communicating with the internal cavity of the container 2 and a flange 15 installed in the flange for opening or closing this hole.

The device contains four identical containers 2. Moreover, the fourth - capacity - without a mixer with a piston 16 installed in it and with a cylinder 17 connected by a hose with a pneumatic system

the theme serves to feed the mass of anti-friction material into the bearing. It, together with the flange I1, is mounted on the support plates 18 connected to the plate 19 by means of the fingers 20 with the possibility of vertical movement along them. The drive sliders 21, positioned with their inclined guides into the mating grooves of the support bars 18, form, together with the latter, a wedge mechanism for lowering the flange 11 with the purpose of joining it with the plate 19 or for raising it. Plate 19 is installed on the bottom plate 22 through interchangeable sleeves

23, whose height corresponds to the width of this type of bearing. In the central part of the plate 19 there is a channel which is closed by a shut-off device.

24 connected via a collar 25 with a rod of a pneumatic cylinder 26. On the bottom plate 22, trays 27 and 28 are fixed for directionally moving bearings with the help of a pusher 29 connected with pneumatic cylinder 30 mounted on a frame 31. An emphasis 32 fixed

on the bottom plate 22, it is designed to regulate the stroke of the piston of the PNRMOCO cylinder 30. The cutter 33 /, representing -: - a two-arm swivel lever, mounted on a tray and designed for single-piece supply of bearings to the filling area, i.e. in the gap between the plates 19 and 22.

The device works as follows.

The spring-loaded couplings 10 are disconnected from the shafts 4 by moving them upwards, and then the containers 2 are moved away, after which the covers 3 are removed together with the agitators 1 and the containers 2 are filled with components of antifriction material. Then

again put on the tank 2 krpuki

and include rotational actuators 5. For 40-50 minutes, the drives 5 automatically switch off. Then noAnpi-oKHHeH couplings 10 are disconnected from the shafts

4 and the containers 2 are pushed aside along the groove of the plate 12, after which the hub 3 of one of the tanks together with the mixer 1 is removed

and install the piston 16 into it. Then the container is turned on and, moving along the groove. Fits, onto the slide blocks 18. Lower the key 17 onto the container and close it. 1 about: by moving the handle 34 connected to the sliders 21, the plate 19 is lowered onto the plate 22. Next, the output channel of the tank is opened by moving the cutters 15 and the bearing cylinder pneumatic cylinder 30 is turned on. The single piece bearings are fed to the filling area by a cutter 33. As soon as the first bearing is in the filling area, i.e. Between the plates 19 and 22, by alternation, the shut-off valve 24 automatically opens the channel in the upper plate 19, compressed air is fed into the piston chamber 2 and the bearing is controlled by a time relay. After the filling time, the cutter 24 closes the channel in the upper plate 19, turns on the pneumatic cylinder 30 and delivers a new one: a bearing, which, pushing and moving the filled bearing along the trays 27 and 28, takes its place. Then the bearing filling cycle is repeated,

After the entire mass of antifriction material has been consumed, the container 2 together with the flange 11 returns to the plate 12, is installed above the fitting 35, the cover 17 is removed and compressed air is supplied through the fitting 35. The piston 16 rises to its highest position and is manually removed from the container. Then the container is refilled with the components of the antifriction material, the cover 3 is put on with the stirrer 1, the container is installed under the shaft 9 and the coupling 4 is connected to the shaft 4 of the mixer 9 with the shaft 9.

Then the drive 5 of the agitator rotation is activated. In the meantime, the filling area of the bearings

This is a new tank, filled with a mass of antifriction material, and fillings are made.

The frequency and quality of filling with the lubricant, in the proposed device, is provided by the mechanism of joining the top plate 19 with the injection agent, which tightly presses the flange I with the conical part to the top plate I9 with the conical opening. The tight pressing of these parts to each other and the presence of a cone protects the top plate o-v of lubricant on its surface during operation and, accordingly, at the end of this lubricant on it and then separating it into the bearing filling area.
