The Design of Screw-Drive Mechanism for Testing Device

Abstract:

The main structure of bearing frame for pressure test device and it’s functions are described in this paper. For the pressure test device with float collar and float shoe, the screw transmits movement with standing pressuring load. According to the needs of actual production and the requirements of test sample pressuring, this paper designed a drive mechanism for screw rod, calculated the stress and checked the correlated stiffness. The result shows that it is reasonable, safe and reliable for screw-drive mechanism, depending on the operation behavior of float collar and float shoe pressure test device.
