Title: Oil pressure levitation trapezoidal screw thread
Inventor: UCHIDA MASASHI
IPC: F16J15/18
Filed: 2010-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an oil pressure levitation trapezoidal screw threads which have high screw efficiency and can be employed even in a device of high-speed heavy load because the trapezoidal screw thread has a large sliding friction resistance due to a metal-to-metal contact of flank surfaces and very poor screw efficiency in converting a rotating torque to a driving force and also because a ball screw is not suitable in operating a mechanical device at high speed and by a large force due to the limit of peripheral speed.SOLUTION: By preventing the flank surfaces from contacting each other by sealing spaces between flank surfaces of the trapezoidal screw thread with a seal material and by supplying an oil pressure corresponding to an axial load to levitate the thread, the screw efficiency can highly be improved so that the oil pressure levitation trapezoidal screw threads can be used even in a device of high-speed heavy load.

Abstract: PROBLEM TO BE SOLVED: To compensate time delay even if it is occurred in a period from when a direct-current voltage is detected to when a voltage corresponding to the result of this detection is applied to a motor.SOLUTION: Each time a direct-current voltage Vdc is detected, the value of the voltage Vdc and the lapsed time after a zero cross point are recorded in association with each other.
