Abstract
PURPOSE: To reduce abrasion of a seal sliding surface to a large extent while maintaining a proper sealing effect by supplying oil to a rotary body such as a universal spindle, through a fixed adaptor portion.
CONSTITUTION: Oil sent from an oil supply hole 25 of an upper holder 15 is supplied to a slipper metal 6 through an oil passage 26 and nozzle 23 in a coupling 3. In this case, a seal sliding surface between a fixed portion like upper and lower holders and a rotary portion like the coupling is sealed in the shaft direction by a V-ring 21 to reduce abrasion of the sliding surface remarkably. A lip portion 21A of the V-ring 21 is then being deformed up left by a hydraulic pressure from the oil supply hole 25 due to shortage of deflection force, howerver, a hydraulic pressure from an oil supply hole 27 of an adaptor 17 is given to the left side of the lip portion 21A through an oil groove 28 to offset the hydraulic pressure from the oil supply hole 25 on both sides of the lip portion 21A, and thus the lip portion 21A provides a sufficient sealing effect.
