Description

The invention relates to mechanical engineering.

The purpose of the invention is to increase the reliability of the link by eliminating the possibility of its self-disassembly during operation, as well as simplifying the technology of manufacturing the joint: it is a link.

FIG. 1 shows schematically a connecting link, side view; FIG. 2 - an inner plate of the link; in fig. 3 — outer plate of the link; in fig. 4 - roller.

The link plate consists of two parts, each of which contains an inner 1 and outer 2 parts, rollers 3 and fasteners 4. Part of plate 1 has elongated wedge holes 5, and part of plate 2 has shortened holes 6. The length of the first hole is longer than the length of the second hole by an amount equal to half the diameter of the roller and more. The inner parts of the 1 plates with elongated wedge holes 5 are mounted on the rollers 3 at the points where the bald spots 7 are formed. In this case, the roller is passed through the wide opening with the O2 axis until the edges 8 are aligned.

with the flat 7, it moves along the wedge-no. 7 slot to the axis 0. and is wedged between the faces 8. Then, the outer parts 2 by the shortened wedge holes 5 and 6 are installed adjacent to the inner parts 1 by 1 (cylindrical end surfaces 9 of the rollers 3 and fasten with the inner plate-: UP-fastener elements 4. Cylindrical surfaces 9 are wedged in these plates, between faces 10, Tilt angles d and oij of the faces of the holes of the inner and outer parts are different, and the rollers are wedged

 5 in both holes in one position corresponding to the axis Oj. The pitch of the corner part 2 of the plate t is equal to the pitch of the link t, In the assembled link of the face 8 of the internal parts of the 1 plate

20 abut against the shoulders 1 of the rollers 3 and prevent the link cheek from moving to the inner, as well as to the outer side. Arc 12 holes 6 of the outer part 2 of the plate prevents

 moving the rollers 3 along the link, thereby eliminating the self-disassembling of the links during transportation, installation and large sagging of the idle branch of the chain traction unit in the conveyor.

Claims (1)

CONNECTING LINK FOR A DRIVING LAMINATE CHAIN, containing plates with wedge grooves, bounded by semicircular arcs located at the edges of the plates, and connecting these plates to cylindrical rollers with flats made at the places of installation of the rollers in the grooves of the plates, as opposed to , in order to increase reliability by eliminating the possibility of self-disassembling, the plates are made composite - from the outer and inner parts bonded to each other, the narrow ends of the grooves of the inner and outer parts of the plate are offset one relative another, and the length of the grooves of the inner parts of the plates is at least half the diameter of the roller greater than the length of the corresponding grooves of the outer part of the plate, and the center-to-center distance of large semicircular arches on the outside of the plate in which the cylindrical ends of the rollers are fixed is equal to the chain pitch.
