通常采用控制游隙的方法来控制角接触轴承的接触角β,误差很大;而用J-6915仪来测量β,则可达到较理想的要求。本文着重介绍该仪器的工作原理及测值误差。附图5幅,表2个。
Usually used to control the clearance method to control the contact angle of angular contact bearings β, the error is large; and J-6915 instrument to measure β, you can achieve the desired requirements. This article focuses on the working principle of the instrument and measurement error. Figure 5, Table 2.
