Original scientific paper The relationships between the existence of gear teeth cracks as a cause and symptoms emerging as housing vibrations that can be detected with signals measured was investigated numerically and experimentally. Experimental measurements on one-stage gear drives have been carried out involving gears built in with different notch length in tooth root. Signals measured as ac...

The theoretical study of the acoustic characteristics “workpiece-mandrel” technological system during gear-teeth milling has shown that for calculating sound pressure levels, it is necessary to determine vibration velocities workpieces and mandrels at their natural frequencies. paper presents results studies processed gear wheels gear-tooth by rolling copying method.

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

This article gives a brief overview of the fracture contacting parts under influence circumferential force in meshing accompanied by rolling and slipping during plastic deformation.

A CNC machine tool for machining designed to facilitate the replacement of cutting tools includes a workbench, motor and hydraulic cylinder. The inner bearing workbench is connected with rotating rod, outer key rod half gear, output end lower rod. machining, which convenient replacing tools, realizes linkage between body adjusting gear by using tooth block, drives move rotation screw adjust pos...

Somer M. Nacy, Member, IAENG, Mohammad Q. Abdullah, and Mohammed N.Mohammed Abstract The Wildhaber-Novikov gear is one of the circular arc gears, which has the large contact area between the convex and concave profiled mating teeth. In (June 28, 1999), a new geometry of W-N gear with parabolic profile in normal section has been developed. This paper studies the generation of rack-cutters for p...

In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...
