VARIABLE THROTTLE TYPE HYDROSTATIC BEARING
Document Type and Number:
Japanese Patent JP2014231857
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a variable throttle type hydrostatic bearing including a diaphragm type variable throttle having great damping property.SOLUTION: A variable throttle type hydrostatic bearing includes a diaphragm 33 whose outer periphery is fixed, and whose face perpendicular to the thickness direction faces a protruded part 31b at a predetermined clearance, and a flow path 31c provided in the protruded part 31b in communication with hydrostatic pockets 2a. The variable throttle type hydrostatic bearing adjusts a throttle amount with the opening of the clearance between the diaphragm 33 and the protruded part 31b. A boss part 33a is provided on the reverse side of the face of the diaphragm 33, facing the protruded part 31b, and a hole 32b slidably stores the boss part 33a to form a liquid chamber 6 between the boss part 33a and itself. A throttle is constructed between the outer periphery of the boss part 33a and the inner periphery of the hole 32b.
