一、应用组合配合的目的(1)满足机构上的要求在机器上有很多地方,要求几个按不同座别制造的轴,跟一个按基轴制既定配合制造的孔相联结;或几个不同座别的孔,需与一个基孔制既定配合的轴相联结。显然,在这种情况下,单用一种公差制度(只用一种基制或只用于同精度配合)是不能满足要求的。唯一的办法,只有利用不同基制或不同精度的组合配合。如[图一],在PC-2混胶机减速器中,轴承
First, the purpose of the application of combination of cooperation (1) to meet the requirements of the organization There are many places on the machine, requiring several shafts manufactured according to different seats, with a hole made by the base shaft system with a predetermined connection; or several Holes in different seats need to be connected to a shaft with a base hole system. Obviously, in this case, the use of a single tolerance system (only one basic system or only for the same precision) is not sufficient. The only way to do this is to use different combinations of bases or different precisions. Such as [Figure 1], in the PC-2 mixer reducer, bearing
