章节摘录

　　Lesson 8　Shafts and Couplings　　Virtually all machines contain shafts. The most common shape for shafts iscircular and the cross section can be either solid or hollow （hollow shafts canresult in weight savings ）.　Rectangular shafts are sometimes used, as inscrewdriver blades, socket wrenches and control knob stems.　　A shaft must have adequate torsional strength to transmit torque and not beoverstressed.　It must also be torsional stiff enough so that one mountedcomponent does not deviate excessively from its original angular position relativeto a second component mounted on the same shaft. Generally speaking, the angleof twist should not exceed one degree in a shaft length equal to 20 times that ofthe diameter.　　Shafts are mounted in bearings and transmit power through such devices asgears, pulleys, cams and clutches. These devices introduce forces which attemptto bend the shaft; hence, the shaft must be rigid enough to prevent overloadingof the supporting bearings. In general, the bending deflection of a shaft shouldnot exceed 0.01 in. per ft. of length between bearing supports.　　In addition, the shaft must be able to sustain a combination of bending andtorsional loads. Thus an equivalent load must be considered which takes intoaccount both torsion and bending. Also, the allowable stress must contain afactor of safety which includes fatigue, since torsional and bending stressreversals occur.
