Nonstandard whorl of especially big lead, pressing groovy method on common lathe cannot be machined. The article is calculated through adjusting, hold former transmission line changeless, treatment gave this kind of whorl. The crucial part of made of baked clay forming machine of furnace of coal of section of tall efficiency tornado is made of baked clay core (be like attached drawing) , 130 × of × of its lead S1=pDµtana=p Tan60 ° =707.

4mm. 6 lines are nonstandard whorl of especially big lead, pressing groovy method on common lathe cannot be machined. It is with CA6140 lathe exemple, press line of transmission of whorl of turning big lead, classics main shaft, 58/26, 80/20, 80/20, 44/44, 26/58, 33/33, 63/100 × 100/75, 25/36, 36/21, 25/36, 36/25, 28/35, 35/28 comes guide screw (lead T=12mm) arrives tool carrier, can machine a lathe of S=192mm(of the biggest lead only nameplate is tagged) , the lead that cannot satisfy a spare parts machines a requirement. To solve afore-mentioned problems, can make calculation with following attune (if still use line of this whorl transmission) : Your × of C=63 of × of the A in type of 12u=192(mm)bdB of × of 12u=A of × of C of × of former lead S=a 100 -- round of drive is hanged to compare Bd10075A=63 in former transmission line -- hang round of drive after simplifying to compare B7512u formerly -- the fixed coefficient that the drive in former transmission line compares sets pattern of S1=12A1u/B1(of especially big lead again, criterion × of A1=AS1=63 of ∴ of 12u=AB1S1BA1A1B of ÷ of B1 of × of S=A × 12u 707.

4=3.

094875B1BS75 × 192(1) is changed brief get A1=63 × 3 × 1.

3 × of 31=63 × 1.

71 ≈ of 31 × 3 × of 63 × 1680 × of 93B15 × 7180 × 71 because deploy,hang teeth of a cogwheel number is limited, hang teeth of a cogwheel to count a requirement to assure to satisfy, make following correction especially: 63 × of A1 ≈ 9063 × of 3 × 903.

7027 × of 095238B181 × 70(2) type (2) , (1) photograph is compared, the error is very small, satisfy treatment requirement completely. This shows, hold former transmission line changeless, need to will be hanged formerly only (A/b) × (C/d)=(63/100) × (100/75) commutation is (A1/b1) × (C1/d1)=(90/70) × (65/27) , can machine piece nonstandard especially big lead 707.
