Abstract

The invention relates to general engineering, in particular to chain conveyor bodies. The goal is to improve the operating conditions by eliminating the self-disassembly of the chain during transportation and operation while maintaining the separation principle for each element of the chain and increasing the service life. Rollers 2 are equipped with rollers 3, which have a diameter of t-dft dp -t / 2, where t is the chain pitch; di is the diameter of the roller; dp is the diameter of the roller. The rollers 3 are provided with grooves 4 and protrusions 5 having the shape of a segment. The grooves 4 are located symmetrically to the protrusions 5 in the vertical plane of the cross section of the roller 3. The longitudinal holes 7 in the plates 1 have a broadened elongated middle part with rounding defined by the formula 2h-i-dt, where t is the length of the middle part of the groove; h is the height of the segmental protrusion; d /, is the outer diameter of the roller. 6 Il.

; The invention relates to general engineering, in particular, to chain conveyor bodies.

The aim of the invention is to improve the operating conditions of chain conveyor systems: conveyors by eliminating the self-disassembling of the chain during transportation and easing the chain tension.

; FIG. 1 shows a chain, side view; on 1FIG. 2 - the same, top view; in fig. 3 - ro-face, side view; in fig. 4 - section AA on 1FIG. 3; in fig. 5 - roller, top view; on 1FIG. 6 - chain link.

I The chain consists of the same for all | links of the plates 1, rollers 2 and rollers 3.

Roller 2 with a diameter d is passed through the hole 7 with the Oz axis of one plate, the hole 6 of the roller 3, the hole 7 with the Oz axis of the second plate, grooves 8 are aligned with

 the narrow part of the holes 7 of the plates 1 and move together with the roller 3 mounted on it along the hole 7 to align its axis with the axis of the hole O |. Then the grooves 4 (or projections 5) of the roller 3 installed in the link are aligned with the projections 5 (or grooves 4)

10 of the second roller currently being installed, forming the total size of two touching rollers 3, equal to the difference between the sum of their two diameters dp and the depth of the slots h. At the same time, the Oh axis is installed

IB rollers 3, the diameter dp of which is larger, the roller is aligned with the axis O4 of the hole 7

half of the step t of the link of the target, grooves 4 and protrusions 5 with depth and height h, and also holes 6 are made. The plates 1 have longitudinal through holes 7, which in width correspond to the diameter d of the annular plates. After this alignment, the second roller is passed through the holes with the axes O -Or-O, the groove 8 is aligned with the narrow part of the holes 7 of the plates and moved to the axis O2. Running out

| The howl of the groove 8 of the roller 2 and rounded by the radio- 20 by a small turn around its axis with the RA | equal to half the diameter d (from the corresponding roller, after which the grooves and protrusions of the roller

| corresponding tolerances for the | displacement d of the groove 8 of the roller 2 through the hole 7 of the plate 1).

I In the middle part 9 of the plate 1 the through hole 7 is expanded to a size that ensures the passage of the roller 2 along the diameter d. The dimensions of the roller 3 are determined by the formula:

It-d6 dp i,

where dp is the outer diameter of the roller;

 d - outer diameter of the roller;

: t - chain pitch.

: The dp condition is mandatory, otherwise the circuit

: has the ability to self-select. At that; At the same time, the diameter dp of the roller 3 should not be chosen close to the chain pitch t, since this; leads to the elimination of the condition of collecting: i.e., when assembling the chain, even in the case of the production of rollers 3 with the deepest pa25

relative to each other are displaced and the link becomes self-separable.

Next, on the rollers 2 put on the plate 1 of the next link and set the next video in the above way. The chain can be assembled according to any known scheme.

Disassembly of the chain is carried out in reverse order.
