Cross head device for the mechanical drive of High pressure compressors or pumps

The invention relates to a crosshead device for the mechanical drive of high pressure compressors or pumps.

In the case of the engines with cylinders arranged opposite one another, there is only one crank drive per crank Cross head and push rod present, with the piston of the opposite cylinder via a bypass member is in connection with the crosshead designed as a secondary crosshead. In this arrangement, the sum does not

These known crosshead devices exist from one upper each held together with screws and lower, the main and secondary crosshead connecting, the circular path of the crank pin comprehensive connecting link, that when going back and forth under the effect of occurring piston forces. Between the joints of the upper and lower connecting link is here on one side of the crosshead frame in one through the drainage joints are split in two halves the cross-head sap that can be clamped with clamping sleeves and separately, at the end, an intermediate member containing the piston rod or plunger coupling with both Sides axially attached, plate-shaped cross-head shoes, serving as the main crosshead, by means of the horizontal pegs on both sides of the crosshead, screws holding the upper and lower connecting links together.

On the opposite side of the crosshead frame is the second intermediate link, also containing the piston rod or plunger coupling, with both Sides clamped in firmly attached, plate-shaped crosshead shoes serving as secondary crossheads.

With this arrangement, the entire width of the two effective crosshead guide tracks results

represent the resulting screw dimensions and their Number lead to heavy and complex constructions, which increase the effect of the inertia force with the oscillating movement of the crosshead frame « In these known crosshead frames, the crosshead-side push rod bearing is also in a closed design articulated axially on the cylindrical cross-head spigot, readjustment is not possible because of the closed design of the push rod head, just as little is it possible to check the crosshead journal and the crosshead journal bearing without disassembly of the crosshead frame.

The inventive device is thereby characterized in that they have one with two fixed or detachable attached sliding shoes that serve to absorb the normal force provided lower part and an upper part detachably connected to this, and that between the two Share on the side of the main Kreuzkopfschulies * the as Cross-head pin formed in the middle, releasably connected to the piston rod of the first cylinder, arranged is.

An exemplary embodiment of such a device is described below with reference to a drawing.

A particular advantage with this arrangement of the crosshead frame results from the design of the cross-head pin link 5. In the known designs the crosshead bearing is closed in the center of the axis on the continuous cylindrical cross · » hinged head pin, which is in cylindrical bores of the Side walls of the cross head body or the connecting elements is firmly clamped.

Compared to this version, the cross-head pin link offers 5 has the advantage that, due to the increased rigidity, a significantly lower force is applied Bending at the pin 7 takes place, which leads to a reduction in the one-sided edge pressures in the clamping points and in the cross-head journal bearings.

Since the block-shaped central part 6 of the cross-head pin member 5 next to the two cross-head pins 7 also at the same time the connection for the detachable piston rod or plunger coupling 14 is attached, and thus crosshead zapf englled and piston rod coupling block are to be regarded as a © ine unit, those defined by the clamping connection in the case of the cylindrical crosshead pin are omitted Clamping forces.
