SU18117A1 - Device for lapping on the site of the heads of the piston sources of the locomotive in crossheads - Google Patents

Description

This device, designed for lapping the crosshead locomotive in the crosshead, on the site of the piston rod heads, consists of a spindle support bracket mounted on the frame, which informs the rotation of the piston rod, and to bring the crosshead into the reciprocating movement serves as a handle with pivotally attached to it t pami, of which one is associated with the crosshead.

In FIG. 1 shows a longitudinal view of this arrangement: FIG. 2- modification of this device, partly la section; FIG. 3 is a section along the A B in FIG. 2; FIG. four-; modification of this device, partially in section of FIG. 5-slit a b in FIG. four.

On locomotive frame A (Fig. 1), the bolt 6 is fixed to bracket 4, which holds the spindle 8 fitted with a pulley 9 at one end, and the cartridge 7 with a piston rod 8 at the second end. For reciprocating the crosshead 10 on the parallels 11, is intended to have the handle 16 (fig. 1) with the arms 13 and 13 hinged to it, of which the latter is connected to the crosshead jKon oM 10, and the ha is IS with the flange 17 of the cylinder 1.

An automatic reciprocating motion on parallels 11 is intended

a device consisting of a stem 5 fixed on the stem 5, by means of a split ring 18 (Fig. 2 and 3) and a pressure nut 19, a drum 14, which is provided with a driving groove 30 for a roller 21 fixed on the tide 15 of the tubular part 23.- In The internal screwed cavity of the last entry is set screw 34, which, by means of sleeve 26 worn on it, is skirted with crosshead 10, and between the shoulder 22 of screw and sleeve S6 is placed an elastic gasket 30 to relieve crosshead pressure on the stem head. The square end 31 of the part 28 is placed in the sleeve 32 of the bracket 27, which is fastened with a wedge 28 on the frame of the locomotive and on the stuffing box of the cylinder head.

The drum 14 (Fig. 4 and o) instead of the groove 20 may be provided with a protrusion 33, which is included in the slot 34 of the tide 15 of the tubular part 23.

Having fixed the bracket 4 on the locomotive frame A (Fig. 1), the rod o is rotated through the spindle 8 and the pulley 9 connected to the motor, then the crosshead 10 is driven with the help of the handle 16 and tg 12 and 15 E reciprocating motion on parallels 11 (Fig. 1). In this case, when the crosshead will move in the direction of arrow a, its hole 5 will slide onto the rotating head of the rod, the outer surface of which is covered

sandpaper with oil will rub in the inner surface of the hole 3.

In the case of using the device shown in FIG. 5 and 3 or 4 and 5, the drum 14 mounted on the rotating rod 5, with its leading groove 30 (Fig. 2 and 3) or the protrusion 33 (Fig. 4 and 5), through the roller 21 or the slot 34 the tide 15, will return -attachable movement of the tubular part 23 and the crack-10.

The subject of the patent.

1. A device for lapping on the site of piston rod heads / locomotive in crossheads, characterized in that in order to communicate the rotation of the rod, the spindle 8 (Fig. 1) rotated by pulley 9 (fig. 1), which is mounted on the locomotive frame with bolt 6, and equipped with a chuck 7 for connecting with the rod, and for bringing the crosshead 10 into reciprocating motion on the parallels 11, the handle 16 is designed

with hinges 12 and 13 that are hinged to it, the latter of which is connected with the crosshead.

2. Modification of the fixture described in paragraph 1, characterized in that the tubular part 23 serves as a crosshead for automatic reciprocating movement on the parallels 11 (Fig. 2), with a set screw 24, which is articulated by means of the sleeve 26, the last crosshead and guided by the square end entering the bushing of the clevis 27 fastened by the wedge 28 on the frame of the locomotive and on the stuffing box tide, which is in the reciprocating axial movement of the cylinder head 23 on with a leading groove (Fig. 2) or a protrusion (Fig. 4), mounted on a rotating rod.

3. In the case of the device described in paragraph 2, the use of an elastic gasket between the shoulder 22 of the screw 24 and the sleeve 26, in order to soften the crosshead across the rod.
