Abstract

The invention relates to an automatic gear generating device. According to the automatic gear generating device, multiple sets of straight gear, bevel gears and intermittent gears are adopted to carry out transmission, power can be transmitted to a generating component and a line drawing portion by only shaking a handle, and the first intermittent gear and the second intermittent gear can push a line drawing pen, a sticker disk and a toothed plate to move periodically, so that the pen automatically records envelope lines cut in the gear processing process through mutual cooperation of the movements, manual line drawing is not required, and a lot of labor and time is saved. In addition, input of the displacement of the toothed plate is carried out automatically through gear transmission, the moving distance is fixed at each time, manual push is not required, and the experiment accuracy is improved.

Description

technical field [0001] The invention relates to an automatic gear forming device, which belongs to the field of machinery. Background technique [0002] Fancheng method is the most commonly used method in gear machining at present. It is processed according to the principle that when a pair of gears mesh and drives, the tooth profiles of the two gears are conjugate curves, so it is also called conjugate method or envelope method. [0003] At present, in school teaching demonstrations, students are required to first calculate the size of the addendum circle and the index circle, and then push the rack to move a few millimeters of displacement, use a pencil to draw a line along the tooth profile of the rack, and repeat The two actions of pushing and drawing lines are performed to form the envelope of the tooth shape to be cut. This method is time-consuming, cumbersome to operate, very inefficient, and the resected part is not intuitive, and the displacement of the manually mo...
