JIS,Japanese Industrial Standard,Involute Serrations,JIS B 1602 T96i,Translated and Published,by,Japanese Standards Association,Printed in Japan,Translation without Guarantee,In the event of any doubt arising, the original,standards in Japanese are to be evidence,B 1602-1961,Japanese Text,Established by Minister of International Trade and Industry,Date of Establishment: September 1 , 1 961,Date of Reaffirmation: January 1 , 1971,Date of Public Notice in Official Gazette: March 2, 1 971,Investigated by: Japanese Industrial Standards Committee,Technical Committee on Serrations,(Chairman: SAKAKI Eiichi),Divisional Council on Machine Element,(Chairman: NOGUCHI Hisakazu),This English translation is published by:,Japanese Standards Association,1-24, Akasaka 4, Minato-ku,Tokyo, 107 Japan,1970 .,UDC 621.838.211-484,2,JAPANESE INDUSTRIAL STANDARD ' J I S,Involute Serrations B 1602-1 961,(Reaffirmed: 1 971),1. Scope,This standard specifies involute serrations, hereinafter referred to as,"serrations" having the lateral profile of involute curved form and mainly used for,connection between shaft and hole. Provided that, taper serrations are excluded.,2. Symbol and Definition,The meaning of symbols and terms to be used for this standard shall conform to,the following (refer to Fig. 1 and Fig. 2).,a ： Pressure angle (subtended angle between its radius and tengent to the,serration at a point of serrated surface),% : Pressure angle on the basic pitch circle,d : Nominal diameter and basic dimension of large diameter 口)are to,be taken.,D: Large diameter (1) of hole,Note (1) The large diameter means, in the case of shaft, the diameter of,the circle which is formed at the tip of serration, while in the,case of hole, the diameter of circle which is formed at the bottom,of serration.,Dk: Small diameter (2) of the hole,dr ： Small diameter (2) of the shaft,Note (2) Small diameter means, in the case of shaft, the diameter of the,circle which is formed at the bottom of serration, while in the,case of hole, the diameter of the circle which is formed at the,tip of serration.,d0: Basic pitch circle diameter,dg : Diameter of the basic circle (3),Note (3) Basic circle means a base circle from which involute teeth are,formed.,Dtif : Involute limit diameter (4) of hole,dm: Involute limit diameter (4) of shaft,Reference Standards:,JIS B 0401 - Limits and Fits for Engineering,JIS B 1702 -Accuracy of Spur and Helical Gears,2,B 1602-1961,Note (4) Involute limit diameter means the limit diameter which is as,near as possible to the tooth bottom necessary for fitting with,hole and shaft.,历i ; Height of dedendum of hole serration,A* : Height of dedendum of shaft serration,hn : Height of dedendum of hole serration,hf : Height of dedendum of shaft serration,m : Module,Mi : Over pin diameter (5) of hole,M : Over pin diameter (5) of shaft,Note (5) Over pin diameter means, in the case o/hole, the distance between,two pins inserted respectively in two confronting tooth,grooves, while in the case of shaft, the distance between which,each pin has been inserted.,R ： Roundness at serration bottom of hole,r : Roundness at serration bottom of shaft,s0 ： Tooth thickness (along the length of arc) over the basic pitch circle,: Basic pitch (circular pitch on the basic pitch circle),U : Diameter of the pin to be used for measurement of over pin diameter,w0 : Width (along the length of arc) of serration grooves on the basic pitch,circle,土 : Shift coefficient,z : Number of teeth,E : Ratio of variation on the thickness of serration grooves to that on the,over pin diameters,F : Ratio of variation between tooth width to that of over pin diameter,Fig. 1. Illustration of Symbols,3,B 1602-1961,Fig. 2. Over Pin Diameter Measuring,3. Fundamental Elements of Construction,3, 1 Module As the basis of tooth size the following six grades of modules shall,be adopted.,0. 5 0. 75 1. 0 1. 5 2. 0 2.5 (unit in mm),3. 2 Number of Teeth Numbers of teeth shall be from 10 up to 60.,3. 3 Pressure Angle Pressure angle on the basic pitch circle shall be 45°.,3, 4 Effective Tooth Height Effective tooth height shall be 0. 8 m.,3. 5 Amount of Shift Amount of shift shall be 0. 1 m.,4. Basic Form of Tooth,The basic rack of serration shall be as shown in Fig. 3.,Fig. 3. Basic Form of Tooth,Basic pitch line,ESI,A,L,I,EOT,Remarks: Basic pitch circle of serrations shall be tangential to the gear cutting pitch line of the,basic rack.,5. Fundam6ntai Formula,The fundamental formula shall be given as follows so as to enable each dimension,to be calculated out.,Nominal diameter:壮=0+0.8+2力7"=0+1)〃2,Basic pitch:,Base circle diameter ： ds^=dQ cos a0,Basic pitch circle diamet……
