Description

.one -"

the dimension of the stroke, determined by slider 1, is very good here, since practically slider 14 almost does not work; 25 gear that transmits rotation to the second bar shaft of the upper carriage.

A modification of the center carriage self-balancing is the transmission to the second carriage, shown in FIG. 3, is arranged as follows. From the bar shaft of the first half of the carriage, the sprocket 17 by the silent chain 18 transmits the rotation of the sprocket 20 fastened or cast for-one with the asterisk 21, from which again the sprocket 22 on the bar shaft of the second half of the carriage is transmitted again by the silent chain 31. Here chains 18 and 31 are made of a constant length and operate constantly in a tensioned condition, in view of the following device: on the bearing bush of the rod shaft, one end of the ha 55, (fig. 3), having a constant length the second end on the axis of the intermediate roller / P; similarly, the ha 36 goes to the second half of the carriage. Thus the mechanism works like a scissors. The intermediate roller / is fixed by the ends in sliders 55-57 (Fig. 5) moving in the slots of the bracket 34. The bracket 34 is attached to the side frame 75 of the machine. To facilitate the movement of the sprocket 20-21, sit freely (on ball bearings) on the roller 19. An excitement can be a reverse combination: the sprockets 20-21 on the roller are fixed in the sliders 33-37, and the shaft 19 is free on ball bearings.

The subject matter of the invention.

1.Bankabrosh using two upper carriages, balancing each other, characterized in that to eliminate the tilting moment arising during the movement of the carriages, the shaft 72 carrying the lifting gear 77 is located between the spindles, and to transfer a variable speed to the upper bar shaft 8 by one from the carriages endless chains 18 and 57, of which one chain 18 bends around the drive sprocket 77 sitting on the bar shaft of the other carriage, and the driven sprocket 20 on the intermediate roller 19, and the other chain 57 bends around the sprocket 21 on the roller 19 and sprocket 22 on the shaft 8, and for tensioning the chains 18 and 57 when lifting and lowering the carriages are guide rollers 28 and 24 rotatably attached to the intermediate roller 19 and is pulled action gueotivovesov 27 and 30.

2. A change in the adaptation for transmitting a variable speed to the rod shaft of the second carriage as described in paragraph 1, characterized in that the intermediate roller 19, bearing sprockets 20 and 27, is mounted on sliders 55 and connected to the rod shafts of both carriages by means of 55 and 36 serving when raising and lowering the carriages to move the sliders 55 along the slots of the bracket 34 attached to the frame of the machine.
