Description

The utility model relates to mechanical engineering and can be used in serial production of elements and components of the control system of guided missiles.

The closest prototype in technical essence is the “Device for the liquid processing of bearings”, RF patent No. 2100104, in which the washing liquid is supplied to the working area under pressure, which requires additional sophisticated equipment. In addition, the device is further complicated by the fact that in order to create flushing fluid flows in the working area, it becomes necessary to use a device that generates fluid jets pumped by the pump unit through groups of nozzle channels with different angles of inclination to form a tangentially directed fluid flow that rotates the bearings during flushing.

The disadvantage of this device is its complexity and bulkiness.

The technical task of the utility model is to create a simple and easy-to-use device for flushing bearings during incoming inspection of their supplies and during the mass production of components and elements of the control system of guided projectiles containing a significant number of bearings.

This problem is solved in that the bearing washing device comprises a mixer with a cylindrical container made of electrically conductive material, the base of the container is equipped with an earthing bolt, a cover is installed on the container, a manual drive is mounted on the cover, kinematically connected to the gearbox on which the cylindrical cartridge is mounted, with a radially hooks with a tapered end installed on its outer surface for tight fit of bearings on it with their inner ring.

The utility model is illustrated by drawings.

In FIG. 1 shows a sectional view of the overall arrangement of the device, where

1 - mixer capacity;

2 - the base of the tank;

3 - grounding bolt;

4 - capacity cover;

5 - manual drive;

6 - gear;

7 - a cylindrical cartridge;

8 - hooks with a tapered end;

9 - bearings.

In FIG. 2 - cassette. In FIG. 3 and 4 - bearing tightly mounted on the tapered end of the hook. In FIG. 5 is a top view of a cassette with hooks radially mounted on its outer surface and bearings mounted on their conical ends.

The bearing flushing device operates as follows.

The tank 1 is filled with a washing liquid, which are used, including flammable ones, such as gasoline, alcohol, etc. The bearings 9 are mounted on a tapered end of the hooks 8 by a tight fit and placed on the cylindrical surface of the cartridge 7 and connected to the gearbox shaft 6 of the manual drive 5. Then the assembly is immersed in a container 1 and hermetically closed by a cover 4. Rotating the manual drive 5 creates an oncoming laminar flow washing fluid in the direction of the bearings 9. In the process of rotation of the manual actuator 5, a turbulent fluid movement is formed on the reverse side of the bearings 9, flushing the rear side of the bearings 9. Since the bearings 9 are mounted on a radial of the cylindrical surface of the cartridge 7 mounted hook 8, when rapid actuator 5 is rotated they move at an angle to the oncoming fluid flow. The tangential component formed in the flow in this case exerts a force on the outer ring of the bearing 9, untwists it and drives the entire bearing 9. In this way, the entire volume of the bearings 9 is flushed.

Due to the fact that flammable substances (gasoline, alcohol, etc.) are used as a washing liquid, static electricity is generated during their friction against the walls of the tank, which must be eliminated. For this, the tank 1 is made of electrically conductive material, and its base 2 is equipped with an earth bolt 3.

Thus, a simple and easy-to-use device was created for flushing bearings during incoming inspection of their supplies and in the process of mass production of components and elements of guided projectiles, where they are widely used.
