A. Amelina the Device and repair of wagon axle box roller bearings. M.: Transport, 1975, S. 239...253), comprising a housing, a locking mechanism napressovyvanie parts, drive it and move the heater or induction type, or made in the form of an oil bath.Using such plants produce separate press the right rings on the axle of the wheelset with a mandatory cooling the resulting Assembly.However, the mounting rings on a hot landing requires considerable time to work. In addition, it requires specially equipped premises (“hot shop”), which greatly increases the cost of production and worsen the working conditions of staff.Also known installation for Assembly cold press-on site train wheel pair on and.with. The USSR № 1344568, 23 P 19/02, publ. 15.10.1987, comprising a housing, a locking mechanism napressovyvanie parts, made in the form of a retractable spring-loaded Cup, the actuator is moved in the form of a cylinder and two brackets.With this setup MONEE structural features leads to great cost of time and therefore increase costs.The closest solution to the claimed combination of essential features and the achieved technical result from its use is the installation design for Assembly cold press-on site train wheel pair on the patent of the Russian Federation No. 2155659, 23 P 19/027, 61 To 5/00, publ. 31.05.1999.

Original position.In the initial position before working on the position In apresski (see Fig.2) in the center of the zone of location of installation for cold apresski on rails 36 is supplied a pair of wheels 14.At this time, the hydraulic cylinder 9 with a glass 6 are expanded outwards, allowing installation on glass parts 37, designed press on the axis 35 of the pair of wheels 14. The Cup 6 is maximiliana levers 21, 22 capture 18 deployed (raised) position G, that the rolling underneath a pair of wheels 14, and a retractable stop 10 is pushed to the left (original) position.Step 2. The press-fitting.Before apresski on retractable spring-loaded glass 6 alternately wear (completed) scheduled to the press-fitting part 37. Then the hydraulic cylinder 9 with a drive rotation 16 on command from a remote control rotates counterclockwise (see Fig.1), placing it in a horizontal position.After that, the levers 21, 22 by means of a hydraulic cylinder 23 reversing down, grab the axis of the pair of wheels 14 and raise it until it stops in the housing 20 of the grip 18, the locking in position of apresski almost coaxially with the cylinder 9 and a retractable spring-loaded stop 10.Next on the next command from the remote control turns on the cylinder 12 by moving up the V plunger 11 and thereby pushing the stop 10 to its contact with the butt-axis 35 of the pair of wheels 14. Signal using the sensor 34 is transmitted to the remote control. Then remove the latch 7, and then under the action of the spring Cup 6 is pulled out of the rod 8 of the cylinder 9 and abuts against the end face of the axle 35.After switching on the hydraulic cylinder 9, the piston rod 8 nachinaet them on the axis 35 of the pair of wheels 14 to a stop.After apresski cylinders 9, 16, 12 are switched to reverse, returning the appropriate mechanisms to original position. The hydraulic cylinder 23 remains in the same position, holding the wheel a couple of 14 lines apresski. On command from the remote control turns on the hydraulic cylinder 29 and through the rack 30 turns the pinion shaft 25 and is rigidly associated with the shaft grip 18 with a pair of wheels 14 180.On retractable spring-loaded Cup 6 is installed another set of repressively parts, and operation apresski repeats. Then, the hydraulic cylinders 9, 16, 12, and 23 are switched to reverse, all mechanisms installed back in its original position, and a pair of wheels 14 with a pressed on both ends of its axis 35 parts is lowered onto the rails 36 and sent to the next process position or to the warehouse.Unit is ready for the next production cycle.The use of the invention allows to:to provide a significant increase in the performance of repairs by eliminating the need to perform multiple operations (lower pair of wheels for tilt-up device, unfixing it ressouce);to reduce the cost of repairs by eliminating the need for additional lifting and turning device is press-parts at both ends of the axis.
