Size of friction face sheets for clutchThis standard specifies the size series of friction face sheets for clutch, JB/T9190--1999bZxz.net
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. Figure 1
