CONTROL DEVICE FOR MEASUREMENT OF PARAMETERS OF SLOT SHAFTS OF AGRICULTURAL MACHINES

Abstract

        The types of splined joints and the relevance of the topic are described, the technical conditions of accuracy in the manufacture and restoration of splined shafts of agricultural machinery are given. The design of the control device for measurement of design parameters and roughness at their manufacturing and restoration is developed. The device for measuring the parameters of the splined shafts is made in the form of a plate on which the main components and parts are placed. All readings come through an analog-to-digital converter to an electronic computer and a profilograph-profilometer. In addition, to measure other design parameters of the splined shaft and the roughness of other surfaces can be installed additional sensors similar to the above. The sequence of operation of the device is specified: in the centers of a dividing head and the back center the reference splined shaft from which by means of inductive sensors all controlled parameters and surface roughness are removed and their admissible limits are established is established. The definition of the value of the allowable installation error is given. The requirement which the scheme of installation of preparation has to satisfy is defined. Conclusions are made on the conducted researches.
