DEGRADATION OF THE STATE OF A BALL TRACK AT THE ZP 6600
Original language description
The article deals with the examination of the state of the ball track at the heavy machine ZP6600/Z79. It gives results of material exams which were taken on given samples and it describes the progress and results of the numeric counting for the state of tenseness. The used method works with the ending parts at the bottom of part of the ball track when it touches the ball. The decision about the renovation of the track depended on the determination of the groove size degradation at the ball track. The material tests were undertaken on the given samples of the bottom part of the ball track at the heavy machine and a numeric simulation of the tenseness state in the contact area of the ball and the bottom part of the track. The result was an evidence for the decision about the depth of the turned layer of the material in order to create a new groove of the bottom part of the ball track. The material tests were realized in an external cooperation with the company UNIPETROL RPA s.r.o., a testing laboratory number 1050 accredited by ČIA. The numeric simulation of the tenseness was made in the VÚHU a. s. on the 3D model of the contact by a method of the ultimate elements.
