我们聊聊在机械设计中，我们必须掌握的有关轴毂联接的知识！轴毂联接是轴毂与轴相连接的轴上零件，常见齿轮、带轮等。联接使回转零件在轴上***和固定，以便传递运动和动力。Wetalkaboutthemechanicaldesign,wemustmastertheknowledgeabouttheshafthubconnection.Shafthubconnectionistheaxlehubandshaftconnectedtotheshaftparts,commongear,beltwheel,andsoon.Theconnectionenablestherotatingpartstobeandfixedontheaxistotran***itmotionandpower.与平键联接比较，花键联接在强度、工艺和使用方面有下列特点：在轴上与毂孔上直接而均匀地制出较多的齿与槽，故联接受力较为均匀；因槽较浅，齿根处应力集中较小，轴与毂的强度削弱较少。Comparedwiththeflatbondconnection,thesplineconnectionhasthefollowingcharacteristicsinstrength,processanduse.Moreteethandgroovesaremadedirectlyandevenlyontheshaftandhubhole,sothejointforceismoreuniform.Becauseoftheshallowgroove,thestressattherootofthetoothis***all,andthestrengthoftheshaftandhubisweakenedless.矩形花键联接是应用***为广泛的花键联接。应用广泛。如航空发动机、汽车、燃气轮机、机床、工程机械、拖拉机、农业机械及一般机械传动装置等等。渐开线花键的齿廓为渐开线，分度圆压力角α有30°及45°两种。齿顶高分别为0.5m和0.4m(m为模数)。Therectangularsplineconnectionisthemostwidelyusedsplineconnection.Itiswidelyused.Suchasaeroengine,automobile,gasturbine,machinetool,engineeringmachinery,tractor,agriculturalmachineryandgeneralmechanicaltran***issionequipmentandsoon.Thetoothprofileoftheinvolutesplineisinvolute,andthepressureangleofthedividingcircleis30and45degrees.Thetopofthetoothis0.5mand0.4mrespectively(Misthemodulus).)
