Abstract
The invention relates to machine-building. A helical gear consists of pinion and wheel with teeth placed on those, these are in engagement one with another, at that the pinion and the wheel are arranged as double ones by separation of pinion and wheel crowns into two equal parts with circular grooves of width c = 10...14 mm, at that the second crowns of the pinion and the wheel are turned in round direction with respect to the first crowns of the pinion and the wheel by angles φand φ, respectively, besides that straight generatrixes of side surfaces of the teeth of the crowns of pinion are replaced by curvilinear generatrixes with radius of curvature, and the teeth of the crowns of pinion and wheel are characterized by non-standard profile that has addendum h= 1,25mand angle of engagement α=17,5°, at that the angles φand φare:;,wherein b– width of toothed crown of pinion (wheel); β – angle of inclination of teeth ∆=0,0075...0,02 mm – parameter of curvilinearity of generatrixes of side surfaces of teeth of crowns of pinion at the ends; m– module of engagement in normal cross section;- minimal radius of curvature of side profiles of the teeth of the pinion;- radii of curvature of involute side profiles of pinion and wheel in pitch point; z, z– numbers of teeth of pinion and wheel;- radii of pitch circles of pinion and wheel ;- radius of base circle of the pinion;- radius of addendum circle.
