Gear Fan Chengyi is a special equipment for gear processing, its use method is relatively simple, but it requires a certain level of technology and operating experience. The following is a detailed introduction to the use and application of gear fan chengyi:
The use of gear fan chengyi is as follows:
1.According to the modulus m of the rack cutter, the pressure angle of the indexing circle and the number of teeth z of the processed gear, calculate the indexing circle and the base circle diameter of the machined gear, as well as the root circle and the tooth top circle diameter of the standard gear, positive and negative displacement displacement gear.
2.The drawings drawn with blank circles, indexing circles, base circles, etc. are fixed on the disc as blanks, the slide plate (with rack) is placed in the middle position, and the standard gear quadrant is facing the rack, and the indexing line of the rack cutter is tangent to the blank indexing circle, and the standard gear is made.
3.Move the rack to the right extreme position and open the gear.
Application of Gear Fan Chengyi:
The Fan Cheng method uses the principle that when a pair of gears mesh with each other, their conjugate tooth profiles are envelopes each other to process gear teeth. When machining, one of the rounds is the cutter, the other round is the wheel blank, they maintain a fixed angular speed ratio transmission, completely and a pair of real gears mesh transmission with each other, while the tool is along the tooth width direction of the wheel blank for cutting movement, so that the tooth profile of the gear is the envelope of the cutter blade in each position. If an involute is used as the tooth profile of the cutter, the envelope is also involute.
In the actual processing, the process of forming an envelope line at each position of the cutting edge can not be seen, so the transmission process between the wheel blank and the cutter is realized by the gear fanchengyi, and the various positions of the cutter blade are recorded on the drawing paper with a pencil, so that the process of the tooth profile is clearly observed.
The above is the specific introduction of the use and application of gear Fan Chengyi. It should be noted that the operating procedures should be strictly followed during use to ensure the safe and stable operation of the equipment. At the same time, for operators, it is necessary to have a certain level of professional knowledge and skills in order to better master the use skills and application methods of gear fan chengyi.
