Device for washing and drying bearings quality

The alleged invention relates to mechanical engineering, namely, devices for washing and drying parts, for example, rolling bearings, and can be used in the repair and maintenance of railway rolling stock, in the subway and other transport enterprises related to the carriage of goods in contaminated places.

A known installation for washing bearings, comprising a washing chamber made with sections of primary and finishing washing, a bath for washing liquid located above it that is scented against the system, a loading section, a washing section, a mechanism for moving bearings along an inclined chute and fixing an inner bearing ring, a mechanism drive

displacement. To improve the quality of the sink, it is equipped with a rotation drive, a shaft, a fork pusher, a cross member, a pneumatic actuator with a rod, a lever link, shutters of the washing chamber, a clamp, a flexible kinematic connection, and the mechanism for fixing the inner ring of the bearing is made in the form of a conical mandrel and a support disk.

The clamp is mounted freely on the conical mandrel with the possibility of contacting with the outer ring of the bearing, and the conical mandrel is mounted on the shaft and kinematically connected by means of a flexible kinematic connection to the rotary drive and kinematically connected via the fork pusher and cross member to the pneumatic drive, and the latter kinematically through the lever link and cross member connected with the shutters, and the supporting disk is pivotally and coaxially with the mandrel with the possibility of clamping and providing rotation inside it relative to the outer ring of the bearing in the washing process, in the nip has channels for supplying the cleaning liquid into a gap between the bearing rings (See. Russian Patent №1712001 IPC 08B 3/02 from 01.02.1989g.).

The disadvantage of this installation is the bulkiness and complexity of the kinematic scheme, as well as the significant investment of time in washing bearings.

The closest technical solution is a device for washing and drying parts, including a washing chamber, a bath for washing liquid, perforated drive drums to accommodate the workpieces, a pump and a pipeline for supplying washing solution.

air duct (see, for example, AS USSR No. 435872, class B 08v 3 / 06.1971 - prototype).

Having a sufficiently high productivity, the known installation, at the same time, does not provide reliable cleaning of hard-to-reach places in the machined parts, for example, rolling bearings.

This goal is achieved in that the device for washing and drying rolling bearings, including a washing chamber, a bath for washing liquid, a mechanism for placing and rotating rolling bearings with an electric drive, a pump and a pipeline for supplying a washing solution, an air duct, is additionally equipped with a braking mechanism for the outer rings of bearings made in the form of a fork mounted on a vertical rack with the possibility of its movement and connected through a system of levers with the body of the washing chamber and with a driven pneumatic core, with a spring-loaded liner located inside the fork and mounted on it, with the possibility of rotation around its axis, a clamping bar, and also mounted on the pipeline for supplying the washing solution, movable pipelines with nozzles, and the mechanism for accommodating rolling bearings is made in the form of interconnected bushings with discs mounted on them to accommodate bearings.

The essence of the invention is illustrated by the drawing, where Fig. 1 schematically shows a device for washing and drying rolling bearings; figure 2 is the same, a section aa in figure 1; Fig. 3 - braking mechanism; figure 4 - mechanism for the placement of rolling bearings, fragment.

The device comprises: a housing 1, a pump 2, an electric drive 3 of a mechanism for locating and rotating bearings, pipelines with valves 4, a bath 5 for washing liquid with overflow and drain pipes and partitions. In the bath there is a sensor 6 for measuring and monitoring temperature, a level gauge 7 and heating elements 8. In the upper part of the body 1 there is a washing chamber 9, in which there are fixed pipelines 10 for washing liquid and movable ones with nozzles, an air duct 12 for supplying air during drying bearings after washing, braking mechanisms 13 with a system of levers 14 and a pneumatic cylinder 15, as well as assembled bearing blocks 16. Above the bathtub 5 there is a compartment where an air preparation unit 17 and a panel 18 are installed for placing an electric pneumatic valves control system 15 and the pneumatic cylinder braking mechanism. In the upper part of the housing 1, an exhaust hood 19 is mounted to remove vapors when washing the bearings with a hot detergent solution.

The braking mechanism 13 is made in the form of a fork 20 mounted on a vertical strut 21 using the axis 22. The insert 23 and the spring 24 are dressed on the axis inside the fork. The spring constantly presses the liner against the stop 25, the spring force is regulated by nut 26. The axle 27 is fixed to the liner a clamping bar 28 is mounted, with the possibility of rotation about the axis when braking two outer rings of bearings of different diameters. To move the rack 21, it is connected with a system of levers 14 and a pneumatic cylinder 15.

The mechanism for placing the bearings consists of assemblies (figure 4). Each assembly includes a sleeve 29 with a seat disc 30 for bearings. Structurally, the bushings are the same and differ only in the seat for the corresponding bearing (type 30-92710AL-1; 30-62310; 30-32310M (AL-1); 3032613M; No. 302, 304, 308, 202). There is a pin 31 at the upper end of the sleeve, and a groove 32 at the lower end. The lower end of one sleeve is inserted into the upper end of the other to fit, the pin enters the groove and provides transmission of rotation from the lower sleeve to the upper.

The installation works as follows: the heating of the washing fluid is carried out with the help of heating elements 8 in the setting mode to the temperature ЗЗ-ЗЗ С. Simultaneously with the heating of the liquid, bearings are loaded, for which each bearing is mounted on its corresponding sleeve (Fig. 4) and is thus collected inside the washing chamber bearing blocks 16 (Fig. 1,2). Install movable pipelines 11 with nozzles in the required position so that the jet of washing liquid falls on the corresponding bearing surface. Then they switch from the adjustment mode to the automatic one, which ensures the washing and drying operations of bearings in specified time modes. During automatic washing, the rotation mechanism of the bearings and the pump work. After a set time, the braking mechanism 13 of the outer ring of the bearing is engaged. The pneumatic cylinder 13 is triggered. The posts 21 are brought together, the spring bars 28 abut against the outer rings of the bearings. Springs 24 are compressed and braking occurs

outer rings of bearings. After some time has passed, the pump is turned off, the cylinder 15 is again turned on and the braking mechanisms return to their original position, compressed air is supplied to the washing chamber 9 for drying the bearings. After a set time, the rotation mechanism of the bearings automatically stops and the supply of compressed air stops, the bulb automatically lights up, signaling the end of the installation.

The present invention improves the quality of the wash, and this, in turn, increases the efficiency and durability of the bearings, which ultimately increases the operational performance of the rolling stock. The automatic mode of operation of the device, its compactness and tightness increase safety and improve working conditions, in addition, the presence of an operator is not required during its operation.
