Strain Control Driving Equipment of Equi-Biaxial Tension Tester

摘要

Bush the invention is slidably installed on the pair of guide posts 10, the guide posts 10, which lower end is fixed on to the base frame 90 by jangbong shape of the strain control drive of the biaxial tensile testing machine 21, the bush 21 is fixed is fixed to the mounting opening (34) fixed to the upper portion of the rotating plate 20, the rotating plate 20 which allows the vertical movement installed between the guide posts pin 35, the ball screw 30, which is fixed to the medium, and naeseol the bearing 32 into the housing 33 where the upper ends of the guide posts 10 fixed to the medium that is spiral in combination with the screw 30, the ball a ball screw nut 31, is provided at the lower part of the housing 33, a driven pulley 61 connected to the ball screw nut 31, is fixed to the base frame (90) decelerates the rotational force of the drive motor 40 a reduction gear (50) to convert the The drive pulley is installed in the lower portion of the shorthand 50 to rotate about 60, the drive pulley 60 and the drive device 100 consists of the power transmission means 70 is disposed between the driven pulley 61 is provided and, the encoder 80 is connected and fixed to the support frame 81 has a drive shaft 51 extending from the reduction gear 50, in a computer is a tensile testing machine (300) operated by the drive apparatus 100, and based on the setting value of the program analyze the signals received from the various measuring devices when it reaches a pre-set set value is the while converting the drive direction of the drive motor 40 to be able to perform a tensile test.
