Abstract

The invention relates to a gear generating instrument, belonging to the field of teaching aids. The gear generating instrument comprises a transmission mechanism, a tooth drawing mechanism and a base, wherein the transmission mechanism is fixed to the base, and the tooth drawing mechanism is fixed to the transmission mechanism; the transmission mechanism adopts a spatial ordinary gear train, and comprises a cylindrical gear, an incomplete gear and a bevel gear, wherein one end of the bevel gear is provided with a hand-cranking turntable which is taken as the input part of the gear train; the tooth drawing mechanism comprises a tooth drawing pen, a spring and a rack pressing plate, and is arranged on a round paper tray to realize the tooth drawing function. The gear generating instrument is simple in structure, accurate in transmission, convenient to operate, and high in efficiency, teeth can be automatically drawn, the distances between the adjacent tooth profiles are equal, and round paper does not need to be adjusted during fixing in the experiment process, therefore, the problem that a horizontal guide plate needs to be repeatedly moved for a plurality of times, while in the moving process, the moving distances can be probably too large or small, so that the needed moving distance can be achieved only through a plurality of times of adjustment, is solved.

Description

technical field [0001] The invention relates to a gear fan forming instrument, which belongs to the field of teaching auxiliary equipment. Background technique [0002] At present, the gear fan used in the auxiliary teaching laboratory is generally mechanical, and its structure includes a horizontal guide plate with a rack, a guide rail, a gear-based disc, a round paper tray, and a rack pressing plate. During use, it is necessary to draw the tooth shape by manually moving the horizontal guide plate step by step to form the required tooth profile. Therefore, in the process of experimenting, it is necessary to repeatedly move the horizontal guide plate many times, which may easily cause the moving distance to be too large. Or it is too small and needs multiple adjustments to achieve the required moving distance. The tooth width line drawn by this operation is not only uneven in density, but also very inefficient. At the same time, students need to repeatedly adjust the positio...
