该外啮合齿轮传动的齿形(发明证844858)借助两种渐开线齿条刀具在主动齿轮和从动齿轮上形成。图a所示为切制主动齿轮,参加形成加工齿条的渐开线齿形切齿刀1;图σ所示为切制从动齿轮,参加形成加工齿条的渐开线齿形切齿刀2(可以使用模数铣刀)。图B表示直齿传动的端截面,主动齿轮3具有凸面的齿形,而从动齿轮4具有凹面的齿形。主动齿轮的齿形,由用切齿刀1切制而成,它为渐开线凹面的包络线构成。从动齿轮的凹面齿形,由用切齿刀2切制而成。它为渐开线凸面的包络线构成。
The toothed toothed profile (Invention No. 844858) is formed on the driving and driven gears by means of two types of involute rack knives. Figure a shows the preparation of the driving gear, to participate in the formation of processing rack involute tooth cutter 1; Figure σ shows the driven gear, to participate in the formation of processing rack involute tooth cutter 2 (You can use modulus cutter). Figure B shows an end section of a spur gear, the drive gear 3 has a convex toothed profile and the driven gear 4 has a concave toothed profile. The gear form of the driving gear is made by cutting with a cutter blade 1 and is formed by an involute concave envelope. The concave gear of the driven gear is made by cutting with a cutter blade 2. It consists of an involute convex envelope.
