A Novel Artifact for Evaluating Accuracies of Gear Profile and Pitch Measurements of Gear Measuring Instruments

چکیده
− Evaluation of measurement performance of a gear measuring instrument (GMI) is not easy task since a master gear with sufficient accuracy has not been available. The manufacturing the master gear with an ideal involute form is very difficult and the accuracy of the master gear is not able to be estimated. Therefore, we have proposed a new artifact named Double Ball Artifact (DBA) which consists of a base plate and two balls for evaluating the gear profile measurement performance by the GMI [1, 2]. It has advantages of inexpensive, accurate, and calibrated with traceability. The DBA, however, is able only to evaluate the profile measurement capability of the GMI. In this paper, we describe a novel artifact evaluating the profile and the pitch measurement performances of the GMI simultaneously.

Advanced Calibration Method for Pitch Artifact
Abstract − The pitch measuring accuracy for gear measuring instruments (GMIs) is evaluated by measuring a calibrated artifact. We proposed a novel artifact which called multiball artifact (MBA). The MBA is composed of the pitch balls assumed to gear teeth and the reference axis assumed to a center axis of gear. The MBA can be calibrated more accurate than a conventional pitch artifact. When the...
متن کاملMeshing Error of elliptic cylinder gear based on tooth contact analysis
In order to study the dynamic meshing characteristics of the elliptic cylinder gear and obtain the meshing error of the gear transmission system, the two-dimensional static contact analysis of the gear tooth surface is carried out by using ANSYS software, and the key parts of the contact area of the tooth surface are determined. Then, the dynamic meshing model of the elliptic cylinder gear is e...

This paper describes an upper bound analysis of cold forward extrusion of spur gears with modified tooth profile. Spur gear geometrical parameters such as module, number of teeth, pressure angle, bore radius and addendum modification factor were input to a computer program written in Visual Basic. Then spur gear, billet and extrusion die cavity were modeled automatically in SolidWorks. For uppe...
متن کاملA Comparative Study of Tooth Wear, Mechanical Power Losses and Efficiency in Normal and High Contact Ratio Asymmetric Spur Gears
The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity. In this work, the di...
متن کاملInfluence of Addendum Modification Factor on Root Stresses in Normal Contact Ratio Asymmetric Spur Gears
Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...
