銷軸連接及限位

1.銷軸連接的軸向限位方式1.1過(guò)盈連接過(guò)盈連接就是在銷軸和軸套之間有一定的過(guò)盈量，裝配時(shí)銷軸結(jié)合面被壓縮產(chǎn)生周向壓應(yīng)力和徑向壓應(yīng)力，軸套由于被撐大而產(chǎn)生周向拉應(yīng)力和徑向拉應(yīng)力，使銷軸和軸套牢固地連接在一起，不產(chǎn)生軸向運(yùn)動(dòng)和轉(zhuǎn)動(dòng)，以達(dá)到軸向定位和防轉(zhuǎn)的目的。1.2限位塊在銷軸上銑出一個(gè)平面，在側(cè)壁上焊上或用螺釘緊固一個(gè)限位塊，是較簡(jiǎn)略避免銷軸向竄動(dòng)與旋轉(zhuǎn)的有用辦法，因?yàn)殂姵龅钠矫娌淮?，故避免旋轉(zhuǎn)的扭矩較小，通常選用輕載或中等載荷。1.3改變銷結(jié)構(gòu)改動(dòng)原銷軸的布局，加大一端直徑并銑扁，卡在焊于側(cè)壁的防轉(zhuǎn)套中，可有用地避免銷軸的軸向竄動(dòng)與旋轉(zhuǎn)，其效果強(qiáng)于上述布局。1.4軸端擋圈這種結(jié)構(gòu)是在支座的側(cè)面焊接一個(gè)內(nèi)徑與銷軸相同的圓環(huán)，在圓環(huán)上攻出螺紋孔或圓錐孔，同時(shí)在銷軸伸出的一端鉆出一個(gè)定位槽或與定位銷配合的孔，銷軸裝上之后用螺釘擰如螺紋孔或用定位銷插入銷孔以達(dá)到防轉(zhuǎn)和軸向定位的目的。使用緊定螺釘固定使用定位銷固定開口銷限位1.5采用防轉(zhuǎn)曲拐這種結(jié)構(gòu)的銷軸有兩部分組成，一部分是銷軸，另一部分則是曲拐。在曲拐的一端鉆出一個(gè)與銷軸直徑一樣的孔，另一端攻螺紋，然后將曲拐和銷軸焊接到一起形成一個(gè)整體。裝配時(shí)在支座的側(cè)面加工出一個(gè)螺紋孔，用螺栓將曲拐上的螺紋孔和側(cè)壁上的螺紋孔連接到一起，這樣便可防止銷軸轉(zhuǎn)動(dòng)和阻止銷軸的軸向運(yùn)動(dòng)。2.限位銷的選擇2.1彈性開口銷(DIN11024)Dimemionsi2.限位銷的選擇2.1彈性開口銷(DIN11024)Dimemionsi誼mmDe&CHPtionofaspiinEcotterforholediameterd*!-5mmasmomind.diameter,galvanized.Ex&mpleMmcnunLingPermissiblelateraloffsetofNumberofcoik戳驢ownSpringcotter5DIN11024—galvanizedHWdlimfitThlaAxlecrihaftOuterdiim』4T54Ca切址tramh毋Weifhtink(petj.3pj?sefrdfn9E11-22.2&4224S.8I。刷3.2mor*than11.2opto14*s2■&13754merethan14upto202D?+10i.4106.6laB95mcr<than20叩tg26SO心113s6』m^rethan upM342&974816917106J87mcTflthan34upto456330??網(wǎng)211W擎"1L&gmtiirtIhaji45up1口5673。150&325.511,S12,504MAMHaLWiresp,ADIN2076PqualityrequiremenLEacMidii叫toDIN17223Execution:endsrutfreebumSurfacetreatiiient:e.g.phosjihated^fakanized^cadmium-plaiedFtnni用bie"irittlQ陌qrturnd誼rn^ter：EarseacDDTdin^toDIN2O&51}UisrrcDinm?iiFd?dLoconnectthesp]ing!otterh此htti?unitto*beLockrd]scthatitcaniw，betost.304不銹鋼R型參數(shù)（僅供參考）血眩H(qsO￡&，!th(iuO15有3.T5L212flT4.15i2+S5&.751.5La?555_35LjgJSS?；LZ_I6松白9.幅6mL8*399.562*4019-i7.Q土3*45臣一58._j2.3*57福ft.65Ab*即17.893柘0ir59.5舞醞20.5123.S*fi525.8134*花而11454*9。?64w27_795+13Q35.923.4&*13j脾，22.L 一皿^—規(guī)格表述：M氣2.2安全銷(DIN11203)DimensionsinMillmetersSPAEMl/R血0DimensionsinMillmetersSPAEMl/R血0WLIL2hblb2b30d20曲Shaft潮a233-0507.542&2r?13.57,55043.6327,5233-0519.545661114a50<53.6328233-05210545661111850153.632&5233-05311.545661114950453.632g233-054115ig5577n159594,5445923M5611.5,45&67149504.53.63&.59233-05515.660601217,514,563644512.5?Permissibledeviation:d1of4Sto^.5可一3-0.2;±0.5aftH1f.域樣rwSt?E){,￡■?_)dtJiiiltiijl(trid，.，■%aftH1f.域樣rwSt?E){,￡■?_)dtJiiiltiijl(trid，.，■%N*IM513.15J5T『53346F&j帽3M55?.M4449Fs>3J445。頌3J44%1ES1*JU1IF111.11X2Jl^MHSJ4*JIfi'1-5lfrWLW5W138"3V13V】WfW■Ifl"1bl"Af?推魅看蚊距襦NHifAri11\r'M"!Biix^iCI'jxuuIOlimulEtouuJ’p1(BD31J-KAST-OiGi)91262.5g11g2.S0*1162.3< 919第§53睹72.5/\3的15l.S10336Z.5IQ留臨925…一T;存LU11S331Q?q1$B2.52.3插銷R呻岫-夾制CiQ R膜4獺晞母制(n)w件號(hào)iOD-.DDZI.ZOAXCC.CA.:M>D件導(dǎo)JLC：C-：4g_3j-j3C.SL-.03D2E:i』lR壞1fi-TlF『i.1AAfib.01mi.riflFtnWfflFf-lRR_FW1R1座向Pfl.09W.13-HJIJ「1郵r2：1,00,73]r06NfflEr-255?25】&向2S.92HR18-】&j「1郵r2iL26,73】項(xiàng)NWl削S?30】&向編舵NKU?！?姬r2i2,i：ii：i,73L06NW碩土晚5?502S.92叫TOihh5.22>.50a73沁：1Lfug.ML[.M60】&同ijji-S-JCU.1996二HQ,?3Xl.yti5.M?6?&向國(guó)顯j/tlJ3R2&OED.2-Q5.：門.3d.73J-UflSkljfyjfg-i5596舀口□ISIM12fi92im25-ico,2405.209LOD,7ELDfi枷『洗5.962519.9128.92HR25-1ED,2405.209LSDLDfiW^3D5.963019.9126.92W125-2CO,2405.：■■!s.ao,7ELDfiWE^SD5.965019.9126.92nR25-2ED.2495.：'-i2.50,7ELDfi加『655.966519.QL26.92im25-3CO,2405.fi3.00,7ELDfiW￡^755.96配知7519.9126.92HR25-1CO-MB5t2B95口.75]?OfiNH16-LD05-966^9ICO］亂日126.325/LfiHRJ]-075?3110..Yj,15□E30]?Ofi8xilMH18-L57.969.42152LDB26.安nRj]-]ocB3110..YjLOO□B30J.Ofi]ffTIS-25Tu969.42252LDBE6.92HRJ]-]ECI.3110..|JL50.530]?0fiNHl8-3n7.969.423。2LDB26.9Gim]-2cc.3110..IJ2.U0.E3D].0fiMF!l8-4n7.969.42如2LDB26.92HR33-25O?3110..IJ2.50□E30]?0fi7.969.425。2LDB26.安HR33-3CCB3110..IJ3.UC□B30J.OfiN1BF__L_Jf土：：年-11.里1E13Z.1甌31TIW.3110.375Mill，&JOk06MfflShinnL就i!?小1IJJ2L0020.9@KREIII-3110.3755,00,KiOk06XH18-L257,961252LO0削.9@公制尺寸規(guī)格表，英制尺寸聯(lián)系匐R-.-所有尺寸單位為亳米＜nun)H■■BWi |1BIcfN承童KN515202530354045505.54 610.82834.120,86.51.4615202530554045506.99 7 10.82834.120.86.52.1815202530JS494550609.42 &10.82834.121.66.53.810-2SJO354045SO60708011.86 914.2283825.27.76.0123015404550607080
