Description

Technical field

The utility model relates to ultrasonic cleaning of rolling bearings, in particular, rolling bearings of a axle box of a railway transport from spent lubricant and its coking products with contaminants in aqueous solutions of technical detergents (TMS) with the automatic execution of the entire cleaning process. The utility model may find application in the repair of wheelsets in the conditions of automated production of car-wheel workshops of car depots.

State of the art

A device for cleaning rolling bearings, containing a drive (tank) with washing liquid, a washing bath (chamber) with washing liquid and nozzles in the form of jet nozzles, a pump for supplying washing liquid from the tank to the nozzles of the washing chamber in recirculation mode, the rotation mechanism of the bearings in the form of support drive rollers installed in the lower part of the washing chamber, and a device (means) for supplying bearings to the washing chamber and issuing them (RF patent for the invention 2188724 B08B 3/02 "Device for washing products"). The known device has the following disadvantages. The washing chamber during the processing of bearings is constantly filled with washing liquid and the jets of washing liquid created by the nozzles are flooded, as a result of which their pressure is weakened and the removal of coked dirt-oil deposits from the surface of bearing parts is inefficient. When the bearings rotate, there is no displacement of the inner ring of the bearings relative to the outer, as a result of which the removal of contaminants and waste grease from the annular space with the rollers is incomplete. These shortcomings also lead to the fact that the cleaning process requires a long time, which, together with the fact that the movement and processing are carried out at the same time only one bearing, does not allow to achieve high performance devices. In addition, means for supplying bearings to the washing chamber are made

separate from the means of their issuance, which increases the dimensions of the washing chamber, as a result of which an increased volume of washing liquid is required.

The closest in technical essence to the proposed utility model is a device for cleaning rolling bearings, containing a tank with washing liquid, a washing chamber with nozzles in the form of jet nozzles located on the side walls of the chamber, and a rotation mechanism of bearings in the form of support drive rollers installed in the lower parts of the chamber, a pump for supplying washing liquid from the tank to the nozzles of the washing chamber in recirculation mode, a drying chamber with a stream of heated air and means for loading bearings into the washing chamber drying and unloading chamber (RF patent 2008104 V08V 3/10 "The machine for cleaning the rolling bearings"). The device also has disadvantages. The washing chamber during processing is not filled with washing liquid and the jets of washing liquid created by the nozzles have sufficient pressure compared to the analogue, but the removal of coked dirt-oil deposits from the surface of bearing parts is also not effective due to the lack of preliminary softening, which requires high washing liquid temperature (80-95 ° С). The removal of contaminants and waste grease in the washing chamber from the inter-ring space with the rollers also occurs incompletely for the same reason that there is no displacement of the inner ring of the bearings relative to the outer one when processing them. For the same reason, the removal of residual washing liquid in the drying chamber from this space during drying by the flow of heated air created by the fan requires a long time and significant energy consumption. This is because the air flow has a sufficiently low pressure and it is impossible to remove the remaining cleaning fluid in a short period of time, and the main share of this process is the evaporation of the remaining cleaning fluid due to the very high temperature (about 110-130 ° C). This device processes one bearing in one chamber. All this leads to the fact that the cleaning process requires a long time and has a low productivity. In addition, this device uses separate means for loading and unloading bearings in the washing chamber and the drying chamber, while in the drying chamber a multiple change in the position of the bearing in space is applied along

the reason for dipping bearings after drying in a bath with kerosene, which also complicates the design of the device. The use of kerosene to eliminate corrosion requires the implementation of the device with the requirements for explosion, fire and environmental safety, and this leads to significant material costs for creating such a design. The device receives and issues bearings with the plane of their diameters parallel to the direction of their movement through the device, which does not allow its flexibility to interact with workshop transport devices (trays) for various layouts of the equipment of the workshop.

The essence of the utility model.

The tasks to which the utility model is directed are to improve the quality of cleaning and the productivity of the process with its explosion, fire and environmental safety and full automation.

Technical results obtained during the implementation of the device are:

- increasing the efficiency of removing contaminants by softening them and increasing macro- and microflows in the washing solution;

- intensification and automation of the cleaning process;

- explosion, fire and environmental safety of the process. These technical results are achieved by the fact that in the device for cleaning rolling bearings, containing a tank with washing liquid, a washing chamber with nozzles in the form of jet nozzles located on the side walls of the chamber, and a rotation mechanism of bearings in the form of support drive rollers installed in the lower part of the chamber , a pump for supplying washing liquid from the tank to the nozzles of the washing chamber in recirculation mode, a drying chamber with a stream of heated air and means for loading bearings into the washing chamber and the drying chamber and their unloading and, a second washing chamber, similar to the first, a second pump for supplying washing liquid from the tank to the nozzles of the second washing chamber in recirculation mode, a second tank with washing liquid, the first and second pre-treatment chambers with activators, an ultrasonic cleaning chamber with piezoelectric transducers located on the side walls and the bottom of the chamber, and a third pump for supplying detergent from the second tank to

chambers of preliminary and ultrasonic cleaning in recirculation mode. Activators in the first pre-treatment chamber are mounted on one side wall, in the second chamber - on the opposite side wall. The drying chamber is equipped with nozzles in the form of jet nozzles located on the side walls and connected through a heater to a compressed air system, and a rotation mechanism of bearings in the form of support drive rollers installed in the lower part of the chamber. In the washing chambers and the drying chamber, movable clamping stops are installed to stop the inner rings of the bearings during rotation of the latter. In the lower part of the preliminary and ultrasonic cleaning chambers, two fixed bearings are installed to accommodate the bearings. All chambers are made in the form of a parallelepiped and arranged with the same step into the passage structure in the direction of movement of the bearings in the order: the first pre-treatment chamber - the second pre-treatment chamber - ultrasonic cleaning chamber - the washing chamber - the second washing chamber - the drying chamber. Means for loading and unloading bearings are made in the form of a movable longitudinal beam, on which seven manipulators are installed with a step equal to the step of placing the chambers. Each manipulator consists of a suspension with two grippers and a mechanism for raising and lowering the suspension, and the traverse is configured to perform horizontal reciprocating simultaneous movement of all the manipulators in the raised position of the suspension by one step, while ensuring that the first manipulator stops only in front of or above the first preliminary camera cleaning, and the last manipulator only above or behind the drying chamber. The fixed bearings in the preliminary and ultrasonic cleaning chambers, the supporting drive rollers in the washing chambers and the drying chamber and the grippers on the suspension are located relative to each other at a distance that enables the movement or processing of two bearings in each chamber at the same time with their diameters in the same plane perpendicular to the direction of movement bearings and parallel to the side walls of the chambers. The washing liquid consists of an aqueous TMS solution with anticorrosive additives.

The traverse of the device may contain a rotation-return mechanism of the last manipulator in the upper position of the suspension at an angle adjustable from zero to ninety degrees.

Figure 1 shows an example of a circuit for constructing a device.

The ability to implement a utility model.

The device, as shown in Fig. 1, consists of a three-level metal frame 1, with a tank 2 and a second tank 3 with washing liquid 4 located on it at the first level. Pumps 5 and 6 are installed on the cap of the tank 2, and a pump is installed on the cap of the tank 3 7. All submersible pumps.

At the second level, a first pre-cleaning chamber 8, a second pre-cleaning chamber 9, an ultrasonic cleaning chamber 10, a washing chamber 11, a second washing chamber 12 and a drying chamber 13 are installed. All tanks and chambers are parallelepiped-shaped and made of stainless steel sheet.

The internal dimensions of all chambers 8-13 have the same dimensions and allow the installation of two bearings 14 at the same time, the diameters of which are located in the same plane 15, perpendicular to the direction of movement of the bearings 14 in the device and parallel to the side walls 16 of all the chambers. Two fixed supports are installed in the lower part of the preliminary cleaning chambers 8 and 9 and ultrasonic cleaning 10, each of which is made, for example, in the form of a metal frame structure having two lateral guides 17 and two supporting cylindrical rods 18. In the lower part of the washing chambers 11 and 12 and the drying chamber 13, a rotation mechanism of bearings 14 is installed, made in the form of two pairs of support drive rollers 19 (in each pair one drive roller, the second driven), located between the side rails 17, while the drive roller of both pairs by means of a chain transmission is connected to the electric drive 20. On one of the side walls 16 of the pre-treatment chambers 8 and 9, two screw activators 21 are installed, connected by means of V-belt drives with an electric drive 22, while in the first chamber 8 the activators are mounted on the right side wall 16, and in the second chamber 9 on the left

side wall 16. In the ultrasonic chamber 10 at the bottom and side walls 16 are piezoelectric transducers 23, made, for example, in the form of a combined package of a radiating lining, two piezoceramic washers and a back lining, tightened with a certain force by a threaded rod. The number of piezoelectric transducers 23 is selected taking into account existing laws of the distance between them and based on the maximum diameter of the bearings 14. In the washing chambers 11 and 12 and in the drying chamber 13, nozzles are made on both side walls 16 in the form of jet nozzles 24, the number of which the location is selected based on the maximum diameter of the bearings 14. The direction created by the nozzles 24 of the jets of washing liquid 4 and compressed air 25 is determined based on their maximum penetration into the inter the glacial space between the bearing rollers 14. In the chambers 11-13 there are two movable stops 26 made in the form of disks mounted on the rods of the respective pneumatic cylinders 27, with each stop 26 on the right side wall 16 installed strictly opposite the corresponding stop 26 on the left side wall 16. The outputs of the pump 5 and the second pump 6 are connected by pipelines to the nozzles 24 of the washing 11 and second washing 12 chambers, respectively, and the nozzles 24 of the drying chamber 13 are connected by pipelines with compressed air 25 through the heater 28 and electric solenoid valve 29. Pre-cleaning chambers 8 and 9 and ultrasonic cleaning 10 have an inlet 30 connected through a non-return valve 31 to the outlet of the third pump 7, overflow 32 and drain 33, connected directly by pipelines and through a manual drain valve 34 to the inlets of the second tank 35 3. The washing chambers 11 and 12 and the drying chamber 13 also have a drain 33 connected directly to the inlet of the tank 35 by a pipe 2. Tanks 2 and 3 have tubular electric heaters 36 and a drain 37 equipped with a manual drain valve 38, as well as level and temperature sensors and bonds Fill and overflow liquids 4 (not shown). At the third level of the frame 1, a longitudinal movable traverse 39 is installed, made in the form of a rectangular frame of metal channels with wheels 40, on which seven manipulators are located. Each of the manipulators consists of a suspension 41, made in the form of a plate with a pneumatic cylinder 42 and two hook-shaped grippers 43 mounted on it, and a lifting-lowering mechanism

a suspension 41 made on the basis of a pneumatic cylinder 44. The manipulators are mounted on the beam 39 evenly with the same step t as the chambers 8-13, with the first manipulator located in the area of the first pre-treatment chamber 8, the last in the zone of the drying chamber 13. A pneumatic cylinder 45 is installed on the frame 1, providing horizontal movement of the beam 39 by one step in the direction of movement of the bearings 14 and its return to its original position. On the traverse 39 in the area of the location of the last manipulator, a rotation-return mechanism 46 can be installed, made, for example, on the basis of a rotary pneumatic cylinder. All pneumatic cylinders 42, 44 and 45 are equipped with sensors for the extreme positions of their rods in the form of typical proximity magnetic switches (not shown in the drawing). The device in the area of loading and unloading of bearings 14 can be installed special elements of the workshop transport devices, such as trays 47, designed to supply bearings 14 to the device and remove them from the device. On all manipulators except the last one, covers 48 are installed for closing the chambers during processing of bearings 14. All chambers have an on-board suction of the vapor of the washing liquid 4 and the exhaust compressed air 25 into the exhaust ventilation (not shown in the drawing). As a washing liquid 4, an aqueous TMS solution is used, for example, “0-BIS M” with a working temperature of 45-55 ° C with the addition of anti-corrosion additives.

The operation of the device in automatic mode is controlled by a control device (not shown in the drawing), made, for example, on the basis of a microprocessor controller and start-up protection equipment.

The device operates as follows.

At the command of the control device, the washing liquid 4 in the tanks 2 and 3 is heated to the temperature necessary for the process, for example, 50 ° C, and the pump 7 is turned on to fill the pre-cleaning chambers 8 and 9 and ultrasonic cleaning 10 and to ensure their operation in constant recirculation mode, and the means of loading and unloading are set to their original position:

the first manipulator above the camera 8, the last above the discharge zone, all the suspensions 41 in the lowered position, all the grips 43 are unclenched. Then control device

reports the readiness for operation of the control system of workshop transport devices, which ensures the supply of two bearings 14 to the loading zone through the tray 47 (the diameters of both bearings 14 are located in the same plane perpendicular to the direction of their movement in the device) and allows the control device to process them. The duty cycle begins with the fact that all suspensions 41 are lifted by the pneumatic cylinders 44 of the lifting and lowering mechanisms. Then the pneumatic cylinder 45 moves the yoke 39 one step in the direction of the loading zone by rolling the wheels 40 along the frame 1, installing the first manipulator above the loading zone, the last - above the drying chamber 13. All the suspensions 41 are lowered, each of the two grippers 43 of the suspension 41 the first manipulator covers the upper part of the corresponding bearing 14. All the grippers 43 are removed by pneumatic cylinders 42 and their hooks at the loading point go into the inner empty space of the inner ring of the corresponding bearing 14. Then all the suspensions 41 along are lifted, while both bearings 14 are lifted, hanging on the hooks of the grippers 43. The pneumatic cylinder 45 moves the yoke 39 one step in the direction of the discharge zone, placing the first manipulator above the chamber 8, and the last - above the discharge zone. All suspensions 41 are lowered, while both bearings 14 are immersed in the washing liquid 4 of the chamber 8 and are mounted on the corresponding supporting cylindrical rods 18 of the fixed bearings, being guided by the side guides 17 in the position when the plane 15 of the diameters of the bearings 14 becomes parallel to the side walls 16 of the chamber 8. Lids 48 cover all chambers. The grippers 43 are unclenched, after which the control device allows the control system of the transport devices of the workshop to supply the next pair of bearings 14 to the loading zone and includes the processing of the bearings 14: the electric drive 22 is turned on, which rotates the screw activators 21, which create a stream of flooded vortex jets in the washing liquid 4 directed to the plane of the location of the diameters of the bearings 14 on their right side, resulting in the combined action of the temperature of the washing liquid 4 (soaking) and pressure the flooded jets of this liquid (machining) soften and detach part of the contaminants loosely connected to the surface of the bearings 14, primarily on the right (in Fig. 1) side, and loosen the firmly bound contaminants

giving their surface a highly developed character. Washed mud-oil pollution due to the pump 7 operating in recirculation mode (washing liquid 4 enters from the tank 3 through the pump 7, the check valve 31 and the inlet 30 into the chamber 8 and through its overflow 32 is discharged into the tank 3 through its inlet 35) merge tank 3, where they accumulate on the surface of the washing liquid 4. The pump 7 takes the cleaning liquid 4 in the depth of the tank 3, which, due to the intake filter, prevents the settling of mechanical particles and dirt-oil contaminants back into the chamber 8. After the end of time image boots (2-3 minutes), the drive 22 is turned off and the activators 21 are stopped. The work cycle ends with this, i.e. the device returns to its original state. Then, a similar second processing cycle begins automatically, during which the first pair of bearings 14 is installed in the second pre-cleaning chamber 9, and a new pair of bearings 14 is installed in the chamber 8. In the chamber 9, the processing operation is carried out similarly to the processing in the chamber 8, only contamination is removed mainly on the left (in Fig. 1) side of the bearings 14. In subsequent operating cycles, the movement of the bearings 14 but to the device occurs in a similar manner.

The processing operation in the ultrasonic cleaning chamber 10 is carried out as follows: the piezoelectric transducers 23 are turned on, the emitting linings of which create acoustic radiation flows into the washing liquid 4, causing the particles of the liquid to vibrate, which leads to the creation of numerous zones with variable pressure in the liquid. Moreover, during the low pressure phase, the liquid ruptures with the formation of microcavities (bubbles), which are closed during the high pressure phase, creating microexplosions with the formation of significant shock forces (this phenomenon is called the effect of ultrasonic cavitation). To the maximum extent, bubbles are formed at the interface between two media, in this case, on the surface of bearings 14, including on the surface of contaminants having a loose developed structure, therefore, the bubbles explode in the pores of this structure, which leads to an effective separation of contaminants and their entrainment into the washing liquid 4 due to micro- and macro-flows created by cavitation and flooded jets of circulating washing liquid 4, followed by removal

through overflow 32 into tank 3. Due to micro-sizes, bubbles are formed in the gaps between the rollers and the inner and outer rings of the bearing 14 in contact with them, which leads to an effective separation of contaminants there as well. After the processing time, the piezoelectric transducers 23 are turned off.

The processing operation in the washing chamber 11 is carried out as follows: the electric drive 20 is turned on, which drives the drive roller in both pairs of support drive rollers 19, the pneumatic cylinders 27 clamp the inner rings of both bearings 14 with movable stops 26, as a result of which they remain stationary when the outer rings rotate. A pump 5 is turned on, supplying the washing liquid 4 from the tank 2 to the jet nozzles 24. The jets formed during this process process the bearings 14 on both sides, removing residual contaminants in the chamber 10 that are not washed away from the surface and knocking out the dirt torn off by ultrasound from the annular space with rollers. The effectiveness of this knocking out is increased due to the rotation of the outer ring of the bearing 14 relative to the inner: the rollers rotate and the places of their contact with the rings are constantly changing, freeing up for jet processing. Washing liquid 4 with impurities from the chamber 11 is constantly removed through the drain 33 to the tank 2 through its inlet 35. After the processing time has ended, the electric drive 20 is turned off, stopping the rotation of the bearings 14, and the pneumatic cylinders 27 open the movable stops 26, releasing the inner rings. The pump 5 is turned off, stopping the flow of detergent 4 into the nozzles of the chamber 11.

The processing operation in the second washing chamber 12 is completely similar to the operation in the chamber 11 and is intended to extend the previous operation in order to more completely remove contaminants from the inter-ring space with rollers, and also to create a clean film of washing liquid 4 with anti-corrosion additives on the surface of all parts after the operation bearings 14.

The processing operation in the drying chamber 13 is carried out similarly to the two previous operations, with the difference that the nozzle is supplied not with washing liquid 4, but with compressed air 25, which previously passes through the solenoid valve 29 and heater 28, which opens for the duration of the operation, and has a pressure of 3-4

atm and temperature 90-100 ° С. During the operation, excess 14 of the cleaning fluid is removed from the bearings 14 while maintaining a dry, thin film on the surface of all parts that provides corrosion protection and does not affect the operational parameters of the bearings 14. The excess cleaning fluid 4 is discharged into the tank 2 through a drain 33, and the processed compressed air goes to the exhaust ventilation system.

In the next operating cycle, the bearings 14 from the drying chamber 13 are moved to the discharge zone and lowered to the tray 47. The control device informs the control system of the workshop transport devices about the possibility of their removal from the device. Subsequently, with each working cycle, a completely cleaned pair of bearings 14 leaves the device. Based on the principle of operation of the device, the processing time in each chamber is the same and minimal, and the total processing time of one bearing is the total residence time in all chambers. If the device has a rotation-return mechanism 46, the last manipulator is rotated in the upper position of the suspension 42 by the required angle before moving from the drying chamber 13 to the discharge zone. In this case, the tray 47 in the discharge zone is docked with the device precisely at this angle. Before the last manipulator returns from the unloading zone to the drying chamber 13, it rotates (returns) to its original position also in the upper position of the suspension 41. After the manual valves 34 are completed, the washing liquid 4 is drained from the chambers 8-10 into the tank 3. If the washing ability is lost With liquid 4, it is drained from tanks 2 and 3 by manual valves 38 through drain 37 into the system for replacing the solutions of the workshop.

Thus, the proposed technical solution of the device allows you to:

- improve the quality of cleaning by increasing the efficiency of removing contaminants by using two pre-treatment chambers to remove contaminants that are not tightly connected to the surface and preparing the surface for basic cleaning, ultrasonic cleaning chambers to remove contaminants firmly connected to the surface (main cleaning), two washing chambers to remove torn contaminants from the surface and internal cavities and obtain an anti-corrosion film and compressed air in the drying chamber and use a stop

the inner ring of the bearing during rotation of the outer in the washing chambers and the drying chamber;

- to obtain high process performance with high quality cleaning due to the processing of two bearings in each chamber simultaneously with the simultaneous operation of all chambers and a sufficiently short processing time in one chamber and due to the fully automatic movement of bearings across the device by introducing a traverse with manipulators;

- to obtain the flexibility of using the device with different layouts of the equipment of the workshop due to the use of a tunable direction of delivery of bearings in the transportation system of the workshop by introducing a rotation-return mechanism of the last manipulator to an angle adjustable from zero to ninety degrees;

- to obtain explosion-, fire- and environmental safety of the process due to the use of washing liquid in the form of an aqueous solution of technical detergents and lowering the temperature of the washing liquid and compressed air drying.
