Description

In the proposed dynamometer for two measurement limits with two springs, two TpyojcHs put on the hook are used, of which one is screwed tightly into the gtorgna of one spring, and the other is screwed into the piston of the second spring only if both springs work together.

The ng drawing of FIG. depicts the vertical axial length of the dynamometer when working with two receivers; FIG. 2 is the same when working with one spring; FIG. 3 view of the dynamometer from above.

The dynamometer (Figs. 1 and 2) consists of a corus A closed at both ends with covers B and C, inside of which are placed pistons E and 3 with spring K and L, partition F, tube I, serving as an emphasis for the latter and tube M and H, of which the first is screwed into the piston .E and freely passes through the hole in the wall Zh and the piston 3, and the second passes through the hole in the roof B and is screwed into the hole 3 to fit the /) and M.

Tubes M and H surround the core of the hook O screwed into the piston of E. Yari on the attachment to the eyelet B and the hook Ор; 1С7-Я1ис / he (their efforts are limited to Kn .- / s; Kim; ots ;; E and 3 pistons are moved to the right. B, sfecTe with piston E is moved connected with it by means of the square P-rack and P, which engages with the upper // 3.

stubble C, mounted on the axis of the striket X, showing on the internal scale of the dial (Fig. 3) in the box D, the magnitude of the forces in the range from zero, for example, up to 300 kilograms.

To measure forces ranging from zero, for example, up to 150 kilograms, use compression of one spring X, unscrewing tube H from piston 3 (Fig. 2). In this case, while moving the piston E to the right, the tube M svbod) passes through a hole in the piston 3, which remains in place. Beli ;;; well, the arrow F on the outer scale of the dial indicates. So that when screwing in and winding the tube H, the piston 3 cannot rotate, the latter is equipped with an ipift T, stroke and;

The dynamometer for two limits of merons with dvzm gruzhiny, different signs that the hook O, screwed into the norshon E of the spring K, resting on the partition G, is surrounded by the tube M, which is attached to the same hook for the spring L, in the case of the joint operation of both springs K and L, what is the tube arranged freely passing through porpheng 3 with tube H turned out of it, in the case of only one spring K.
