Abstract

SUMMARY OF THE INVENTION: a chain comprises a link, each of which is made in the form of outer and inner plates pivotally connected to each other by means of a zipper. A roller is mounted on the sleeve; The outer plates of each link are mounted on a sleeve with a guaranteed clearance. On the mutually inverted surfaces of the inner and outer plates, they are made with annular protrusions by their depressions. The protrusions and depressions form a closed hinge. 2 ill.

Description

The invention relates to the field of machine suppuration, in particular to mechanical transmissions, and is intended for use in mechanisms and machines operating under conditions of high speeds and poor lubrication.

Known roller-roller chains with inner plates pressed onto the bushings and outer plates pressed onto the rollers (GOST 13568-75).

The drawback of the sleeve-roller chain is the high wear rate of the joints with poor lubrication and loss of performance due to the increase in pitch

And - PI,

The chain contains inner plates pressed onto a split otulka and external plates along with grooves on the rollers, which provides improved lubrication of the joints, nose guard - Mdccy. close to the chain according to GOST, and he dug a hinge 1.

I.-l isoGphegoni - increasing the reliability and durability of the chain transmission chains by reducing the articulated wear by closing the hinge and by reducing the dynamic loads by reducing the mass of the chain,

This is achieved by the fact that the chain is formed by inner plates pressed neither bushings and outer plates loosely mounted on the bushings. To limit the axial movements of the outer plates within the clearances, the ends of the bushings are flared or mechanical locks are installed in the holes of the bushings.

The chain hinges form surfaces in the form of annular protrusions on the inner and outer plates located at the junction of the inner and outer plates. The grooves in the plates, into which the annular protrusions of the mating plates enter, provide for closing the hinge.

Claims (1)

The claims A LAMINATED CHAIN containing a link, each of which is made in the form of outer and inner plates hinged together, as well as a sleeve with a roller mounted on it, characterized in that there are no rollers on the outer fabric of the chain design, due to the mass of the rollers the chain mass is reduced. The load is conveyed by the chain through bushings, inner plates. The hinge is double-sided, located in the joint zone of the inner l outer plates, When the chain is working, its hinges are closed. The lubricant supply may be in the cavity inside the sleeve, which is closed with blind mechanical locks. When chains operate in an oil bath, the gypsum bands inside the bush can be opened. In Fig. 1 and in Fig. 2, a general view of the chain is given with a cut of its link. The chain contains bushings 1 on which the rollers 2 are located and the inner plates are pressed in. The outer plates 3 are put on the sleeves 1 with a guaranteed clearance and form a hinge joint in the ear in the area of contact with the darkened plastic. Restricting the occot, h, of the movements of the outer plates of the ICIS according to the onugrech recorded by n; - ERTKEH, is carried out by the mountaineer locks, which can be hollow and hollow, and also by flaring in the youths. may have DPM devices for filling cavities in bushings. The rotational muscle from the r-doomde zazadochki is transferred to the bushings of the chain of y-bushings r, w / grave plates through osgupy - to n, pool, now plates. Each side of the garmin gzudet is loaded with half of the pulling force. Calculation should be made for this pelucin and taking into account the size of the hinge d and I, The use of the proposed chain in a number of industries will increase the reliability of chain ridges, reduce metal consumption, increase their service life, (56) USSR Copyright Certificate No. 1557390, cl. F 16 G 13/00, 1990. The stakes of each link are mounted on a drone with guaranteed clearance, and the reciprocal surfaces of the inner and outer plates are made with annular protrusions and recesses, which are installed with the possibility of contact with mating protrusions and depressions with the formation of a hinge.
