流量计的腰轮转子体是该流量计的主要零件,其要轮的渐开线齿形工作面的加工是整个加工中的关键工序。工作面的尺寸精度、形位精度及表面质量直接关系到流量计的计量精度。腰轮转子体的结构如图1所示。
The waist rotor body of the flowmeter is the main part of the flowmeter, and the processing of the involute tooth profile working face of the wheel is the key process in the whole process. Face size accuracy, shape and position accuracy and surface quality is directly related to the measurement accuracy of the flow meter. Rotor body structure shown in Figure 1.
