The invention relates to mechanical engineering and can be used for flushing the bearings or cover their preservative.From the patent literature it is known a device for liquid treatment of bearings, namely washing, containing the mechanism for moving the bearings on the tray and located above the tray collector grupomacuta.com of the known device is the low quality of washing, as torquing the fluid flow is directed from the upper end, causes the rotation of the cage with the balls and the inner ring, which become a barrier to flow to the opposite side of the bearing.It is also known a device for liquid treatment bearing a tray loading and tray movement of the bearings through the working area placed along the top and bottom manifolds with feeders to them washing or conservation of fluid in both reservoirs with a step equal to the width of the tray, there are groups of channels-injectors, each of which is directed at an angle to the tray for forming the channel group tangential to the separator bearing torquing fluid flow 
A disadvantage of this device is the relatively low quality liquid handling bearings due to the fact that the first same positions washing the conservation of the flow of fluid from the reservoir begins to rotate the cage and the inner ring as fast as possible. The corresponding speed force the balls in the bearing rolled the solid particles of dirt and some of them are pushed into one's own body and the body of the treadmill so that the s, acting as an abrasive, destroy the original roughness and mikrofonistit of the contacting surfaces between the parts of the bearing. As a result, and shrunk into the bearing microparticles dirt and abrasive traces of them in the balls and treadmills rings become a source of increased acoustic noise and dynamic vibrations in the low frequency range, which is registered with appropriate equipment for certification bearing on the accuracy class.The technical result of the invention is to improve the quality of liquid handling bearings and, consequently, increase due to this precision class bearings.This result is achieved in that the device for liquid treatment bearing a tray loading and tray movement of the bearings through the working area placed along the top and bottom manifolds with feeders to them washing or conservation of fluid in both reservoirs with a step equal to the width of the tray, there are groups of channels-injectors, each of which is directed at an angle to the tray formirovaniya by channel group tangential to the separator bearing twisting thread LCD, which in the first group are located vertically relative to the tray, and in the subsequent groups with a gradual decrease of the angle of inclination of the tray and bringing it to tilt in the main groups, with nodes for supplying said liquid to collectors installed on the side opposite the load bearing.In Fig. 1 shows a device, an axial section; Fig. 2 a view of the top tray; Fig. 3 section a-a in Fig. 1, located at the side of the tray unloading bearings; Fig. 4.5 cross sections b-B and b-b In Fig. 2, performed at the location of the channels of the nozzles in the upper and lower headers.In otherwise leave the device tray of the working area, in which the process or conservation bearings 1 made in the form of two tubes 2 and 3 of rectangular cross-section and ruler guides 4 and 5 along these pipes at a distance from each other equal to the diameter of the bearing. Tubes 2 and 3 are both lower manifold, there are groups of channels-injectors 6 8 forming a jet of fluid, which are connected to the pipes 2 and 3 through node 9 from the pump unit 10. The latter is also connected to node 11 for supplying fluid from the upper reservoir 12, which is made of a group of channels-the force is"ptx2">In the first side of the load groups (see left fragments in Fig. 4, 5) channels of the nozzle 6 is directed perpendicularly relative to the pipes 2 and 3 tray ( 90oand bearings 1 lying on it. In the following groups, as the distance from the load and closer to the middle of the tray (see secondary fragments in Fig. 4, 5), and then near the exit of the bearings from the working area (see right fragments in Fig. 4, 5) the angle a between the axis of the channels of the nozzles 7 and 8 and the horizontal plane of the tray, is gradually reduced, thereby increasing the horizontal component of force of the jets of liquid to the separator and ball group bearing 1. Thus in aggregate each group of channels 7 and 8, located in the pipes 2 and 3 the bottom of the reservoir and the upper reservoir 12 forms a tangentially directed to the separator twisting the fluid flow, and energy torquing impact the higher, the smaller the angle a. Moreover, for each neighboring positions in related groups the channels of the nozzle is made so as to create a whirling flow in the opposite direction.Therefore a device for liquid treatment of bearings 1 contains the tray 13 loading the tray, move the bearing washer or preservative fluid. In both reservoirs with a step equal to the width of the tray, there are groups of channels of the nozzles 8, each of which is directed at an angle a to the tray to form this group of channels tangential to the separator bearing twisting of the fluid flow. In the upper 12 and lower 2, 3 reservoirs with side load completed an additional 6 and 7 channel group-injectors, which are in the first group (6) are arranged vertically relative to the tray, and in the following groups (for example 7) with a gradual decrease of the angle a of inclination of the tray and bringing it to the angle of the main groups of 8. Nodes 9 and 11 for supplying said liquid to the reservoir 2, 3 and 12 are installed on the side opposite the load bearings 13 1.The device operates as follows.A transfer mechanism (not shown) provides a step-feed bearing 1 from the tray load 13 in the working area, where they are in the process of moving from position to position, and the stopping time of the will is under the influence of jets of fluid pumped by the pump unit 10 in the upper reservoir 12 and the pipes 2 and 3 the bottom of the collector.On the first line working zone bearings 1 desirous vertical jets directed at them from above and below g the I to nodes 9 and 11 for supplying fluid due to lower values of hydraulic losses will increase. At this point, the liquid is captured and carried away the main part of the dirt, methacryloyloxy details and elements of the bearing.When entering the bearing 1 in the middle part of the working area with groups of channels of the nozzles 7, aimed at different angles to the separators, the latter will be on the first positions slowly, and later on, with increasing intensity to rotate around its axis in one direction or another, revealing previously screened dirt and giving access to liquid jets.At the end of the working zone in the immediate vicinity of the nodes 9 and 11 for supplying fluid jet under maximum pressure and directed channels injectors 8 under the lowest angle a to the separator, spin last as fast as possible to ensure separation and removal of dirt particles remaining in the bearing in the power of the most lasting relationships with its surface. Effective cleaning of the bearings is in the process of moving them from one position this part of the tray to the other, because at this point, each bearing rotating in one direction, falls under the counter-pressure liquid jets.Therefore, compared with the prototype, the proposed device is implemented blastia on microparticles dirt, and more appropriate method of application of this impact, which together provides quality liquid handling bearings and the increase due to this, their accuracy class. A device for liquid treatment bearing a tray loading and tray movement of the bearings through the working area placed along the top and bottom manifolds with feeders to them washing or conservation of fluid in both reservoirs with a step equal to the width of the tray, there are groups of channels-injectors, each of which is directed at an angle to the tray for forming the channel group tangential to the separator torquing bearing fluid flow, characterized in that the upper and lower reservoirs with side load completed additional channel groups of nozzles that are in the first group are located vertically relative to the tray, and in subsequent groups with a gradual decrease of the angle of inclination of the tray and bringing it to tilt in the main groups, with nodes for supplying said liquid to collectors installed on the side opposite the load bearing.
