Gear Fan Chengyi

Abstract

The invention provides a gear fan forming instrument. The gear fan forming instrument includes a base plate, a control control circuit module, a driving motor, a transmission gear, a reduction gear, a rack, a slider and a bearing. The base plate is provided with a guide rail groove. , the slider is provided with a guide rail, the guide rail is matched and connected to the guide rail groove, the rack is fixedly connected with the slider, the motor is fixed on the bottom plate of the base, the control module and the The drive motor is connected, the reduction gear is fixed on the bottom plate of the base through the bearing and meshed with the transmission gear and the rack at the same time, and the transmission gear is fixed on the motor shaft of the drive motor , the gear fan provided by the present invention can realize the control of the sliding distance of the slider, so that each time the moving distance is equal, there is no need to reciprocate the moving distance, the drawn tooth profile is clear and distinct, and the electronically controlled automatic transmission is realized. , improving the drawing efficiency.

Description

technical field [0001] The invention relates to the field of teaching auxiliary equipment, in particular to a gear fan forming instrument. Background technique [0002] At present, the gear fan used in the auxiliary teaching laboratory is generally mechanical. When using it, it is necessary to manually move the slide plate to draw the tooth profile to form the required tooth profile. Therefore, in the process of experimenting, it is necessary to reciprocate Moving the slider multiple times will easily cause the moving distance to be too large or too small during the moving process and requires multiple adjustments to achieve the required moving distance, so the efficiency is low and it takes a lot of time, and the error of manual operation is large and the stability is not stable. High, so that the drawn tooth profile is not clear, which affects the observation of the students on the machining process of the gear fan. Contents of the invention [0003] The present inventi...
