Abstract

The invention relates to a lifting machinery industry, in particular to guiding devices for the rectilinear movement of a prismatic body. The purpose of the invention is to simplify the construction and ensure reliability by eliminating the possibility of distortions with the possibility of 18 18 J / / / 73 / gate-wise movements of the prismatic body. The device contains fixed bases 1 and 2 and a movable prismatic body 20. On the prism 3 rollers 5, 6, 8, 9, 11, 12, 14, 15 are mounted, covering their flexible links 16, 17, 18, 19, the opposite ends of which are fixed on the prismatic body 20. The rollers are placed in the lateral faces of the prism, in the development of which the links form a periodic sequence with identical orientation of the ends of the flexible links. When moving the prismatic body 20, the links 16-19, rolling on the rollers, shorten one of their ends by the amount of elongation of the other, as a result of which the movement is carried out straight, without distortions. 2 Il. % (L with so fie.1

Description

The invention relates to a hoisting and transport machinery and can be used in devices with flexible links that provide a rectilinear movement of a prismatic body.

The purpose of the invention is to simplify the design and ensure reliability by eliminating the possibility of distortions during reciprocating movements of the prismatic body.

FIG. 1 shows a guide device, a general view; in fig. 2 - its scanning along the lateral edges of the prism.

The guiding device contains fixed upper 1 and lower 2 bases, mounted on the latter and lying in the faces, built on bases 1 and 2 of the prism 3, rollers. Rollers 5 and 6 are fixed on the edge 4, on the edge 7-8 and 9, on the edge 10-II and 12, on the edge 13-14 and 15 respectively. The rollers are covered by flexible links 16-19, the ends of which are fixed on the prismatic body 20 according to the scheme shown on the scan of FIG. 2. The end of the flexible link 16 at point 21 bends around the roller 5 of the lower base 2 and the roller 6 of the upper base 1, and the other end 22 is fixed on the prismatic body 20 from the upper base 1. The flexible links 17, 18, 19 form a periodic and closed scan along the perimeter of the upper base 1 sequence.

The device works as follows.

When moving a prismatic body, 20 links 16-19 roll over the rollers. 5, 6 and 9, 8, 9 and 12, 11, 12 and 15, as well as 14, 15 and 6, respectively, shorten one of their ends by an elongation value of the other, as a result of which the prismatic body 20 moves linearly without distortions.

The rotating rollers can be replaced with fixed axles, the friction of the flexible link about which can be reduced by the use of anti-friction coatings.
