Title:
TWIST VIBRATION DAMPING DEVICE
Document Type and Number:
Japanese Patent JP3264294
Kind Code:
B2
Abstract:
PURPOSE: To facilitate processing of a member on the output side by a method wherein a plurality of slide stoppers are arranged peripherally movably in an annular fluid chamber and a choke through which fluid is passable is formed in the recessed part of a member on the output side.
CONSTITUTION: The protrusion part 10a of a slide stopper 10 in an annular fluid chamber 7a is protruded in the recessed part 6c of a member 6 on the output side. A choke C through which fluid flows l is formed between the protrusion part 10a and the recessed part 6c. When the slide stopper 10 is moved in the fluid chamber 7a owing to twist vibration, twist vibration is damped by means of a resistance force generated when fluid flows through the choke C1. In which case, there is no need to form a protrusion part formed on the outer peripheral part of the member 6 on the output side. Thus, lathe machining is applicable on the outer peripheral surface of the member 6 on the output side. Even when it is desired that other choke is formed by using an outer peripheral surface, a high-precise choke is easily formed.
