On the Determination of the Gear Teeth Wear Using an Inductive Sensor

A problem to measure the teeth wear of rotating gear wheels and a possibility to create simple, reliable and inexpensive mobile systems of diagnostics allowing to record the wear in the course of use are presently relevant. The paper presents implemented technical solutions as a result of work. The aim of the work was to prove experimentally that it is possible to measure the teeth wear of a gear wheel using a passive inductive sensor and a positioning disk. The technique to determine the wear uses a phase-chronometric method developed at BMSTU.To reach the objective, an experimental installation was designed and made. Works are performed, and experimental results of used stationary inductive sensors of passive type to measure the ferromagnetic gear wheels wear of reducers in use are received. The technique for defining the points at the output signal of the inductive sensor, which correspond to the specified points of the tooth profile and, in particular, to the profile points on a pitch circle of the tooth of gear wheel has been developed. Experiments allowed us to define the main dependences of signal parameters on the sizes and arrangement of the sensor magnet with respect to the passing tooth in the course of rotation, as well as on the number of the sensor coil turns, speed of gear wheel rotation, and on the gap size between the end face of the sensor and the top of a tooth.The technique for positioning the sensor with respect to tooth has been deve loped. In particular, it allows us to position a sensor at any point of the involute, including also a point of the profile on a pitch circle. This is necessary to adjust the sensor. The conducted researches allowed us to develop a technique for exact measuring system adjustment to a hitch circle of the gear wheel and to develop for this purpose a system of diagnostics and measurement of teeth wear with the wheel being rotated. The results of work performed at the JSC ELARA in Cheboksary city allowed us to develop a design and make a pilot batch of standard ind uctive sensors, which can be used in mechanical engineering in systems of diagnostics of reducers in a diversity of machines and mechanisms.</p

NORMALIZATION OF HETEROGENEOUS COMPUTING CLUSTERS DUE TO USE OF VIRTUAL NODES

Creation of systems of the distributed computing is the new perspective tendency of development of computing systems. To one of actual problems began maintenance of portable of the software of clustered sites. In this article it is offered to use existing means of a virtualization of the computing environment (system VMWare or similar) for simplification of creation of the software of systems of the distributed calculations. Results of measurement of parameters of a bandwidth and a latency of system of synchronization of a cluster for virtual and real nodes are submitted. Results of the made researches allow recommending use of virtual clusters for simplification of creation of systems of the distributed calculations. PACS: 89.80.+h, 89.70.+c, 01.10.Hx 1
