齿轮传动在机械工业中应用非常广泛。但200年来,渐开线齿轮都一直占居统治地位。近年来,机器设计向着高速、重载方向发展,缩小机件尺寸、减轻重量、提高其承载能力和效率就具有极为重要的意义。为此目的,各国科学家均在寻求新的啮合制和新的齿型。1955年苏联诺维柯夫工程师发明了点啮合制圆弧齿轮,1958年苏联公开发表,并命名为诺维柯夫齿轮,引起各国很大的重视。根据研究试验证明:新型齿轮传动的承载能力与相同条件下的渐开线齿轮相比,一般可提高2～2.5倍左右,寿命约提高1倍左右,因此极有发展前途。
Gear drive in the machinery industry is widely used. But for 200 years involute gears have dominated. In recent years, the machine design toward high-speed, heavy direction, reducing the size of the machine, reduce weight and improve its carrying capacity and efficiency is of great significance. To this end, scientists from all over the world are seeking new systems of engagement and new teeth. In 1955, Novikov engineers in the Soviet Union invented the point-meshing arc gear. The Soviet Union published it in 1958 and named it Novikov gear, arousing great attention of all countries. According to the research and test results, it is proved that the carrying capacity of the new gear transmission can be increased by about 2 to 2.5 times compared with the involute gear under the same conditions, and the life expectancy is increased by about 1 time. Therefore, it has a promising future.
