Accuracy of the accuracy of the transmission accuracy, the accuracy of the size, shape, angle, position and other elements of the object, indicating the closeness between the observation, the calculated value or the estimated value and the true value (or the true value considered to be the ideal state). Transmission accuracy is the degree to which the actual value of the gear error element related to the transmission characteristic is close to the theoretical value. It generally indicates the degree of influence of the accuracy of each transmission link in the transmission CHAIN on the relative motion accuracy and uniformity of the end effector. Commonly used indicators include motion accuracy, work stability, contact analysis, and ulnar side clearance.
Transmission accuracy is usually also expressed by errors, including corner error, line value error, and so on. Large error, low precision, small error and high precision. The transmission error is the amount of change in the actual value of the output shaft angle relative to the theoretical value when the input shaft is unidirectionally rotated.
In the ideal transmission, there is an ideal linear relationship between the input shaft angle of the Guangdong vacuum pump and the output shaft rotation angle. However, there is always an error in the actual output shaft rotation angle.
The transmission error and the hysteresis are related to each other. The three-leaf Roots vacuum pump is often affected by the eccentricity, the base section, the tooth profile error caused by the machining, the matching clearance caused by the assembly, and the radial runout. The system hysteresis is the synthesis of the gear pair hysteresis of each stage, and the hysteresis of each gear pair is the combination of the following three types of errors: (1) the inherent error of the gear itself (Class I error): the inherent inherent of a single gear before it is assembled Machining tolerances include tooth thickness reduction and geometric eccentricity. This is the main source of the return difference.
(2) Device error (Class II error): Error introduced due to part manufacturing and mounting errors. Except for the center-to-center deviation, it is generally smaller than the hysteresis generated by the Class I error source.
(3) Other errors (Class III error): Errors introduced due to temperature changes, elastic deformation, etc. These types of backlash are special and relatively less influential. If necessary measures are taken in the design, they can generally be avoided.
