SU364365A1 - PNEUMODIZER OF THE CROSS OF MALTESE MECHAIISMS - Google Patents

Description

There are pneumatic loaders of the Maltese mechanisms, including at least one pneumatic cylinder mounted on a support with a poril rod with a fork, whose axis carries a work roller interacting with a profiled element rigidly connected with the Maltese cross.

The proposed load loader differs from the known ones in that the pneumatic cylinder rod is connected to its plug via a spherical NODIININK iia whose axes but both sides are set with sliders placed in the bearing directions and the work roller interacts with at least one supporting roller on which axes are also mounted The slides entering with a gap into the other guide supports, and these sliders have one slip plane parallel to the axis of symmetry of the fork, and the other at an angle to this axis.

These differences increase the speed of the cross and the steppes of balancing the moments of inertia forces of the masses brought to the cross.

Ma FIG. 1 depicts the described pneumogloader, side view; in fig. 2 is a view along arrow L of FIG. one.

Pneumatic loader includes a cylinder /, rigidly mounted on the base, with a piston 2, the rod 3 of the cylinder is pivotally connected to the fork 4 through a spherical bearing 5,

on the common axis with which the sliders 6 are placed, placed on the onor 7. The fork 4 carries at least one support roller 5, on the axes of which the sliders 9 are mounted, entering with guide into the supports 7 and having one helical B and another inclined sliding surface B, and a working roller 10 mounted in the grooves of the plug 4 movably along its axis of symmetry in such a way that reliable contact between the working 10 and supporting 8 rollers is blurred.

On the axis of the working roller 10, the cassettes 11 are mounted, mating with it through bearings 12. The working roller 10 interacts with the profiled element (cam :) 13, which is rigidly connected to the cross through shaft 14. In this case, the smaller the diameter of the working roller 10, the greater the degree of balancing of the moments of inertial forces 1i and masses, reduced to the shaft of the Maltese cross.

Pneumatic loader works as follows.

During the period of rotation of the cross, as a result of the interaction of the profiled element 13 with the working roller 10, which is elastically formed, the balance moment occurs, which is transmitted to the shaft of the cross through the shaft 14.
