A bidirectionally rotatable ratchet unfolding flywheel for ball screw inertial capacity

Abstract

The invention discloses a bidirectionally rotatable ratchet-deployable flywheel for ball screw inertial capacity, which includes a forward flywheel assembly and a reverse flywheel assembly; the forward flywheel assembly includes a forward dial, a forward flywheel disc and a forward expansion Mechanism, the forward dial is fixedly set on the screw nut assembly, the forward flywheel sleeve and the forward dial form a ratchet structure, and the forward expansion mechanism is set on the forward flywheel to change the rotation of the forward flywheel Radius; the reverse flywheel assembly includes a reverse dial, a reverse flywheel disc and a reverse expansion mechanism, the reverse flywheel and the reverse dial form a ratchet structure, and the reverse expansion mechanism is set on the reverse flywheel disc to change the reverse direction The radius of gyration of the flywheel. The impact caused by the change of the rotation direction of the flywheel when the inertial capacity of the ball screw switches the movement direction is realized without changing the rotation direction of the flywheel. At the same time, under the premise of not adding additional devices and using additional energy, the flywheel moment of inertia can be continuously variable and adaptive to different working conditions.

Description

technical field [0001] The invention relates to the technical field of vibration reduction of a flywheel type inertial container, in particular to a bidirectionally rotatable ratchet deployable flywheel used for ball screw inertial capacity, in particular to a vibration reduction system that can be used for a vibration reduction system including a ball screw inertial container Ratchet deployable flywheel with continuously variable moment of inertia and bidirectional rotation. Background technique [0002] In 2001, Smith of Cambridge University invented the "habit container". This new type of mechanical element can provide a very large amount of inertia with a small structural mass. The ideal inertial container element is defined as a single-channel mechanical element with two relatively independent and free-moving endpoints, and the forces at the two endpoints are equal in magnitude and opposite in direction, and are proportional to the relative acceleration. According to ...

Problems solved by technology

[0005] In view of the shortcomings of the flywheel used in the general inerter container in the above-mentioned prior art that the moment of inertia is not changeable and it is difficult to bear the instantaneous large load, it overcomes the impact caused by the inertial capacity of the general ball screw when changing the direction of rotation of the flywheel on the smoothness of the inertial capacity of the ball screw Problem, the present invention provides a bidirectionally rotatable ratchet expansion flywheel for ball screw inertial capacity, which ensures that the inertia coefficient remains unchanged when the ball screw inertial motion direction is switched; and each flywheel does not need to change the direction of rotation, thereby Reduce the impact of ball screw inertial capacity due to the change of flywheel rotation, and at the same time, without adding additional devices and using additional energy, the flywheel moment of inertia can be continuously variable and adaptive to different working conditions
