Cam lift curve of the identification and correction of errors

Volume and the establishment of corrective measures. Specific mapping method shown in Figure 6. Ju 6 (b) of the lift curve of the analytical error correction method for linear equations sneeze I stand corrected trajectory error lift equipment error point on the curve trajectory correction line (Figure 7), the equation is: Y-KX ÷ b (1) where. 1i = ..., 6 the slope of a straight line trajectory correction - correction of the vertical intercept of a straight line trajectory. 2. Point of error very Okuma equivalent access to and correction of the rotation curve determined to make a point on the opposite side equivalent of the same name as the error must be detected by changing the cam base (corner starting position) to achieve specific method is to determine their anonymous 7 calibration track line in Figure 5 the coordinates of the intersection. For example, when the n and b equivalent, by equation (1) can be obtained; yYKXb) cz = b + J ... by (2) and transformed to Figure 6 can be obtained: one by one 1h. =:-J '. 'Equation (3): Ah. , A ix, Ah, Ah Ⅲ eleven calibration curve before and after the limit point port, b of the lift error,:,: Dan, one by one limit point b, JA mouth one by one-way rate of change of angle correction. 3. Corrected lift curve calculation error before calibration curve in order to ensure the error limits of each point, after correction still limit point, any error on the calibration curve points must satisfy (4), namely: Ah \≥ Ah) J '~ where: n and b. - Curve,[link widoczny dla zalogowanych], the maximum lift cam side of the error, and d --- a point jc the cam side of the trench line lift is small corner of the error correction point A when the appropriate recognition, the calibration curve of each point on the lift error, by the following calculation. Ct Tian Ah = Ah. Doo-A (5) style (5): Ah. And any point A before and after correction for calibration lift error. At this point, based on the concept of inclusive cam, cam lift error of the maximum expression is: △ == A. A (6) Ah ..., Ah ... ~ cam lift all the errors in the minimum and maximum I Yun final should be noted that given this process a variety of cam curve of error correction method DW, fitness I_} j symmetrical cam; also apply to the Secretary-like asymmetric cam. Involute tester universal integrated error and its correction Tangqi Chang (Institute of Metrology tadpole pedantic) k Abstract ■: the unity of the involute based on years of practical value,[link widoczny dla zalogowanych], for two different types of involute tester universal comprehensive sets the error curve factors were analyzed,[link widoczny dla zalogowanych], and the military pension of Correction. A, Wan Lei involute comprehensive instrument black {tiny storm movement in the transmission gears, gear transport required an angle, the driven gear ratio between shadow turned round should be a corresponding degree. Tolerance standard gear to gear tooth of a turn or a comprehensive Su rotation error is defined as poor. Comprehensive measurement error of gear used to represent measurements. Therefore, the gear will be instrumentation Wyatt instrument verification procedures of the indication error of error with a comprehensive platform to express and set off with a brilliant new opening line of the standard model for examination. Involute instrument accuracy, depends on the measurement error of chain length and size, due to measurement error resulting chain is a link error, so the measurement chain most sensitive to the accuracy of the instrument. Ya rod fixed disk in vain to open Ji equipment (for example: Zeiss Universal involute tester) measurement chain hanging from the mechanical amplifier consisting of various levels. But the wiring of the total amplifier device, as shown: PsKS compared with the function, said: pf (rRs) take on the recent set of differential type barrier reflects the error:} Lu AR} AS a Ap = q ~ Ar or a KtpAR + KA $ known from the above equation,[link widoczny dla zalogowanych], the instrument function of the error Ap institutions won mainly by the radius of the base disk error error AR, AS, and expand the angle of body size of the error and leverage than the other components. (1) A very major error radius of zero by the instrument zero errors and changes caused by temperature difference ? G round home location and to determine the accuracy of institutional system, measuring carriage arch steel skateboard parallel, Bian's Ao installation error caused by eccentricity. Proportional to the error and start angle. (2) AR disk errors In addition to the error with the base circle diameter of Ar Mi similar errors on donkey AR, but still with a lever ratio of r / R = K related to the size, and the error in the opposite direction of this error is the main leap from the oh Manufacture and installation disk itself precision and temperature changes caused by the § I et seq. (3) organization determined mainly by the error △ s slider rotation center coincides with the disk did not strip, move, set the slider does not coincide with the rotation center, steel ruler skateboards and leverage the straightness error roar and leverage ratio, imbalance caused by the temperature. Example: SP 60 involute of a tester with a spiral pattern; 59.979mm cypress timing error curve is quite inclined 0.002ram. To find a cause that instrument zero error 0.003mm, fixed ridicule plate R-= 90,002 mm,[link widoczny dla zalogowanych], Novo A difference of a 0.003mm. Expand model angle of 42, when the instrument leverage infer = ';
