The Distributed Test And Analyzing System For The Planar Enveloping Hourglass Worm Gearing

With the increasingly extensive application of the planar enveloping hourglass worm gearing, it becomes more important to rapid detection and high precision of the manufacture error .The surface of the planar enveloping worm gearing is complicate, and current domestic and international examination concerning its form generally is recur to the general three dimension measure apparatus or the special measure apparatus according to "the type of assemble" principle designed. Therefore, the examination of the manufacture errors has not real been solved.This thesis advances a set of distributed examination analysis system, this system is separated into the chip module and the PC module. The primary aim of the single chip microcomputer circuit of this project is data collecting, it applied the invention monopoly of professor Zhang Guanghui and professor Peng Donglin of Chongqing university, make use of the high frequency inserted pulse, and join together the software to constitute subsidiary calibration distributed on equal time, complete the task of on-line subdivision in the dynamic measure process, finally up pass the data to PC, PC handle it and get examination result. The software adopts the popular program language Visual Basic6.0. The interface is amity, and the operation is simple. The system abandons the serial communication that is low speed and low effect, but change to use the printing port, realizes the high speed, efficient parallel communication, further more choose to use to the ECP (Extended Capabilities Port,) mode of parallel communication. According to the outside physical transfer ability, this mode can automatic adjust the transfer speed, and realize the data communication with the arbitrary speed.In experiment process, aim at the current rotary encoders output is not TTL wave type, the writer designs the hardware integrated circuit by that can turn the current wave into TTL wave, and it obtains the good result. Finally the thesis creates the PCB card of the chip module, and makes use of the HP signal occurrence apparatus 33120A finishing the on-line data collection, give out and analysis the experiment result.
