Description

(54) LEVER COMPENSATED COUPLING

one

The invention relates to mechanical engineering.

Known koitensiruyu & ne above clutches containing two coupled hinged coupling half f. The disadvantage of these couplings is the radial load on the shaft.

Also known is the 1 4-way compensating clutch f containing the driving and driving half-couplings with the fingers and the drivers connecting them 2.

This device is closest to the invention by its technical essence and the effect achieved. However, the disadvantage of such a clutch is its low load capacity.

In order to increase the load capacity, the proposed coupling is equipped with two-arm V-shaped levers freely mounted on the fingers along the lumuffle / kg and each lead is connected to the shoulders of two adjacent levers. In order to compensate for distortions of the shafts, the drivers are connected to the levers by means of spherical or elastic hinges.

FIG. 1 shows an eight-guide coupling, a view along the axis (one of the coupling halves and the casing are not shown); FIG. 2 is a section A-A of FIG. one.

The driving half coupling 1 (Fig. 1) is equipped with four fingers 2-5, and the fingers are driven by fingers 6-9. A lever 10 is hinged on each finger. The shoulder of the sun of lever 5 is called external, and the shoulder of SD is internal. The levers 11 alternately connect the outer and inner ends of the levers. View hinges are spherical., Casing 12 and elastic cover 13 protect

10 clutch from dust. The casing can simultaneously be a reservoir for lubrication.

The clutch works as follows. With the radial displacement of the driven half coupling 14, the levers 10 turn

J5 around the fingers 2, 8 at a small angle, depending on the geometrical parameters of the coupling and on the magnitude of the displacement. Depending on the direction of the torque transmitted by the clutch, the drivers 11, which bind the outer ends of the levers, work to stretch or compress. At the same time, drivers that bind the inner ends of the levers have the opposite load. Shoulders of the forces loading

5, the leads relative to the fingers vary with the radiographic displacement — the coupling half is insignificant, therefore the forces in all the leads are almost the same. The angular displacement of papumufta is provided by spherical hinges of leads. Number

leashes may vary according to need.
