JB/T 9190-—1999 This standard is a revision of ZBJ19028-90 "Clutch Friction Plate Dimensions". During the revision, the original standard was edited, and the main technical content remained unchanged. This standard replaces 2BJ1902890 from the date of implementation. This standard was proposed and assigned by the National Technical Committee for Standardization of Metallic and Non-metallic Coatings. The drafting unit of this standard: Wuhan Institute of Material Protection. The main drafters of this standard: Chen Hefa, Yao Huajun, Zhang Cheng. 152 1 Scope Machinery Industry Standard of the People's Republic of China Size of friction face sheets for clutch Size of friction face sheets for clutchThis standard specifies the size series of friction face sheets for clutch, JB/T9190--1999 Replaces ZBJ19028:90 This standard applies to mechanical friction clutch face sheets (hereinafter referred to as clutch face sheets) of various automobiles, tractors, engineering machinery and gearboxes. The geometric shape of clutch face sheets is an overall circular ring, and other shapes of face sheets are not applicable to this standard. This standard does not involve the surface structure type of friction face sheets. 2 Size series of friction face sheets for clutch The size series of dry clutch face sheets is shown in Figure 1 and Table 1. The size series of wet clutch face sheets is shown in Figure 2 and Table 2. The tooth profile of wet clutch face sheets is an involute tooth profile.
