Applying TCA(Tooth Contact Analysis)and LTCA (Loaded Tooth Contact Analysis) techniques,the influence of pitch error on the meshing behavior of aviation spiral bevel gears with contact ratio 2 0 was studied.
From the point of measuring accurcy,the advantages and disadvantages of measuring methods and data used in measuring pitch errors of large gears are analyzed,which is useful for getting a rational method of measuring pitch errors of largegears
The tooth profile errors and pitch errors of microgear are measured and the measurement precision is analyzed. The experimental results show that measurement principle of the system is correct and feasible, and the developed software can meet the production demands.
The relative spiral angle and pressure angle errors were defined and introduced into the evaluation of the teeth mating precision,which had been carried out by the measurements of teeth form and pitch errors.
This paper introduces several cases of the radial runout of tooth ring, and probes into the influencing factors on and regulating methods for the accumulated error of tooth spacing and the error of tooth spacing.
The experimental results from three different types of SEMs show that high quality gratings with uniform lines and less pitch error can be fabricated by this method, and moiré patterns can also be correctly generated.
The generated key assignments are then usedto construct the perceptual pitch error criterion which is based on noterelatedness ratings obtained from experiments with human listeners.
The paper discusses the pitch error of the tooth rotor in a magnetoelectric angle convert or the error of measurement when the stator has one, two, or four readout one tooth heads.
The high-speed rotating cutter allows the microgrooves to be sharply machined without burrs and accumulative pitch errors, taking account of cutting order.
