彭形齿是齿式联轴器的一种齿形,主要适用于联接两轴或轴和回转机构,在传动过程中一同回转而不脱开的一种装置。当两轴产生相对位移时,鼓形齿可以避免轮齿发生边缘接触,改善啮合面上压力分布的均匀性,并增加许用角位移。一些大型设备如大型混合机、带式冷却机和一些钢铁行业重型设备配件, Peng tooth is a tooth-shaped gear coupling, mainly for connecting the two-axis or shaft and rotary mechanism, in the process of rotation together without turning off a device. When two axes produce relative displacement, the crown teeth can avoid the edge contact of the teeth, improve the uniformity of the pressure distribution on the engagement surface and increase the allowable angular displacement. Some large equipment such as large mixers, belt coolers and some heavy equipment parts for the steel industry,
