To make an animation on a microcomputer, first draw these pictures on a computer. Then you need to solve the storage problem of these picture files in the computer. Finally, these pictures are continuously displayed on the computer screen. At this time, it is necessary to solve the problem of speed of displaying and replacing the screen. In order to solve the above problems, a two-dimensional animation of a crankless tooth difference transmission principle was successfully fabricated on a microcomputer. In the working principle of crankless tooth difference transmission, it is mainly difficult to imagine and understand the second-stage transmission, so the animation design of this paper is mainly for this level of transmission. To this end, we make a section plane along the end face of the planet gear. The actual situation of the section in the transmission process is made into a series of pictures, and the continuous display of these pictures can obtain an animation reflecting the transmission principle. To draw the above series of pictures for the involute internal gear pair, first draw a pair of involute internal gear maps, and then draw the cross section and crank of the two eccentric sections of the crankshaft on the planets. The end face of the bearing. The tooth profile of the gear is mainly composed of the top curve, the initial curve of the root cartoon, the involute profile curve and the root transition curve. The involute curve is the main working tooth profile curve of the gear meshing transmission and needs to be accurately drawn.
The crest and root curves are two concentric arcs that are easier to draw. The tooth root transition curve is related to the type of tool and the curve equation is also complicated. However, in the case of a small tooth difference transmission, the number of teeth of the general internal gear is relatively large, which is far greater than the minimum number of teeth required for the interference of the external gear transition curve. Therefore, there is no interference problem with the external gear transition curve. In addition, when the internal gear is machined by the gear shaping cutter, since the top edge of the shaper blade has no rounded corners, the height of the tooth tip is higher than the tooth tip of the gear, so that the transition curve of the internal gear does not occur. Moreover, the transition curves are very short, so they can be drawn in an approximate way on the screen. Given the basic parameters of the gear (number of teeth, modulus, indexing circle pressure angle, displacement coefficient, tooth height coefficient), after establishing the tooth profile curve equation, this paper uses FoRTRAN language to calculate the gear geometry and profile curve. The coordinate value of each point.
