一、渐开线齿轮的研磨在渐开线齿轮的装配过程中,若通过各种调整方法仍不见效,一对齿轮的大多数牙齿的啮合间隙过小,啮合接触迹线不正确,在这种情况下,一般须进行齿轮的研磨。渐开线齿轮的研磨应在其减速器安装就绪后进行,研磨方法和注意事项如下: 1.根据齿面接触的情况选配适当的研磨膏。一般采用1~#、2~#和3~#研磨膏(以重量计配料比)。 1#研磨膏的配料比:100~#金刚砂(凡尔砂)50％,凡士林油10％,机油10％,石墨29％,松香1％。其中机油、石墨作润滑用;凡士林、松香作调和、粘结之用。以上配料应搅拌均匀。 2~#研磨膏配料比:120~#金刚砂60％,凡士林油40％。 3#研磨膏配料比;200~#金刚砂60％,凡士林油40％。 2.用毛刷将研磨膏均匀地刷在齿轮的牙齿上。如果减速器其他齿轮不需研磨,可在其齿面上涂抹润滑脂。 3.电动机慢速传动减速器。研磨速度一般控制大齿轮的圆周速度在1m/s以下。
First, the involute gear grinding In the involute gear assembly process, if through a variety of adjustment methods still not effective, most of the teeth on a gear meshing gap is too small, meshing contact trace is not correct, in this Under the circumstances, the general need to gear grinding. The involute gear grinding should be carried out after the reducer is installed, the grinding methods and precautions are as follows: 1. According to the tooth surface contact with the appropriate selection of abrasive paste. Generally used 1 ~ #, 2 ~ # and 3 ~ # abrasive paste (ingredients ratio by weight). 1 # grinding paste ingredients ratio: 100 ~ # emery (Vail sand) 50%, petroleum jelly 10%, oil 10%, 29% graphite, rosin 1%. One of the oil, graphite for lubrication; Vaseline, rosin for reconciliation, the use of bonding. The above ingredients should be mixed evenly. 2 ~ # cream paste ratio: 120 ~ # Emery 60%, petroleum jelly 40%. 3 # abrasive paste ingredients; 200 ~ # Emery 60%, petroleum jelly 40%. 2. Use a brush to rub the abrasive evenly on the teeth of the gear. If there is no need to grind the other gear of the reducer, apply grease to the tooth surface. 3. Motor slow transmission reducer. Grinding speed of the general control of the peripheral speed of the gear below 1m / s.
