SU69711A1 - Bespaltsevny swivel track links or drive chains - Google Patents

Description

Already known is besnaltsey connection of links tracked or drive chains, in which at one end of each link there are protrusions, and at the other - the corresponding depressions. In order to reduce friction in such compounds, the described invention provides for the implementation of said protrusions and cavities prismatic. The protrusions and depressions alternate with stiffening ribs, which exclude the possibility of longitudinal and transverse displacement of the links relative to each other.

FIG. 1 shows a diagram of the position of the chain links in their average operating condition; in fig. 2 is a diagram of the position of the links at the time of their connection; in fig. 3 is a diagram of the position of the links with their maximum deviation relative to each other.

Each chain link on one side instead of eyelets is equipped with a system of prisms 1, which are integral with the body of the link. On the other side of the link, prismatic depressions 2 are made. Prisms and depressions in the crown21 Code in. eleven.

are blown With stiffeners J and 5, which exclude the possibility of longitudinal and transverse displacement of the links relative to each other. The pairing of two adjacent links is achieved by the fact that the tips of the prisms 7 are inserted into the corresponding valleys 2, and the links are allowed to freely rotate relative to each other when the track wheel, sloth and extreme support rollers follow the track chain.

The connection of individual links between themselves becomes possible by their mutual movement at a certain angle (an angle of 35 ° selected) in the direction of the non-working position of the chain, considering that convexity side, the floor} from the sag of the upper branch of the track (at the location of the driving wheel at the rear).

The angle of maximum movement of the links to the working side is assumed to be 30 °, but in each individual case it can be made the way it is required by the overall design of the track.

From production considerations, as well as to provide better

removing sand and dirt from the working surfaces of the prisms and valleys of the stiffeners 5 and 5 are supplied with answers 4.

For the same purpose, hole 6 serves as well as a number of other holes not shown in the diagram.

To prevent spontaneous separation of links on the free branches of the track chain when the latter beats at high speeds and when there are abrupt changes in driving patterns, the hinge design provides for a safety device in which a piece of round wire is inserted into the hole; and length, followed by bending of the protruding ends.

The working surfaces of prisms and valleys should be subjected to quenching after casting.
