FIELD: engineering of training appliances utilized in training process during studies of mechanics, physics, theory of mechanisms. ^ SUBSTANCE: training device for demonstration of gearing by means of overhead projector contains body of transparent material in form of plates 1,2, driving disk 5, leading cog 7c with external teeth and following cog 8 with internal teeth, held on axis, and gear couple with external connection. Gear couple is mounted on lower plate 1 of body, one gear 14 of which is connected to following cog 8. leading cog 7 is mounted on driving disk 5, and following cog 8 - with possible free rotation on upper plate of body by means of additional disk 9 and axis 11. ^ EFFECT: expanded demonstrational capabilities of device, unification of devices, demonstrating types of gearings, decreased device dimensions, increased legibility of image on screen and improved efficiency of device utilization during training process. ^ 1 dwg |
