A tooth clutch comprises a bushing with outer barrel teeth with varying curvature and a ring, enclosing it and kinematically connected to it, with straight inner teeth that are in engagement one with another. Outer barrel teeth of the bushing are arranged in the middle part at lengthαwith radius of curvature R, and at sections with lengths (b-)/2, adjoining the ends of the teeth with radius of curvature R, at that R< R. The inner straight teeth of the ring at the end sections with lengths (b-)/2 are arranged as skewed with skew angle, this is found from the expression,where b–teeth length;= (5... 15)•10rad–set value of twist angle of axles of connection shafts of power units;- twist angle of axles that is realized with tooth clutch within end sections of teeth with length (b-)/2;–twist angle of axles that is realized with tooth clutch at length; m–engagement module;=20° - engagement angle; z–number of teeth; R= (0.25...0.35)Rand= (0.2...0.25)b–is taken. |
