Problems solved by technology

Vibration not only easily causes structural fatigue damage and affects the life of equipment, but also reduces the measurement accuracy of instruments and meters, resulting in failure of electrical components such as relays and automatic control systems. At the same time, vibration inevitably produces noise, which affects the normal work of operators and even endangers healthy

Embodiment Construction

[0018] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0019] The force amplitude adjustable shock absorber actuator based on the double slider mechanism mainly includes force output mechanism, eccentricity adjustment mechanism, deceleration mechanism and electromagnetic mechanism.

[0020] combine figure 1 The executive mechanism includes a three-phase asynchronous motor 8, a slider linkage mechanism 1, a spur gear 6, a spur gear 5, a worm gear 7, and an adjustment mechanism 3 (including a transmission screw, an electromagnetic mechanism, a carrier plate, a locking bar, Movable cross), support member 9. The slider link mechanism 1, the spur gears 4, 6, and the spur gear 5 are keyed to the rotating shaft 2, and the spur gear 4 and the turbine 7 are keyed to the rotating shaft. Due to functional requirements, the masses of the two eccentric masses are equal, the eccentric distances are equal, and they are always on t...

Abstract

The invention provides a force amplitude adjustable type vibration absorber actuating mechanism which is based on a double-slider mechanism. One end of two parallel rotating shafts is respectively provided with mutually meshed straight spur gears, a connection shaft of a three phase asynchronous motor drives the straight spur gear of a driving parallel rotating shaft, right ends of the two rotating shafts are connected with sliding-block linkages with the same structure, the sliding-block linkage includes a connecting rod, adjusting sliders and an eccentric mass slider; the adjusting slider is connected with the parallel rotating shaft, the eccentric mass slider is sheathed on a slide bar which is vertical to the parallel rotating shaft, two adjusting sliders are connected by a deflector rod which is connected with a regulating mechanism, a driven parallel rotating shaft is connected with a first straight tooth bevel gear which is meshed with a second straight tooth bevel gear on a worm, a turbine, which is meshed with the worm, is arranged above the worm, the center of the turbine is connected with a first drive bolt, and the actuating mechanism further includes a second drive bolt. The actuating mechanism can be used for reducing mechanical vibration caused by unbalanced force and torque to improve mechanical vibration amplitude.

Description

(1) Technical field [0001] The invention relates to a shock absorber, in particular to an active dynamic shock absorber. (2) Background technology [0002] Vibration is a common phenomenon in production and life. With the continuous increase of operating speed, the vibration of mechanical equipment such as ship power plant has attracted more and more attention. Vibration not only easily causes structural fatigue damage and affects the life of equipment, but also reduces the measurement accuracy of instruments and meters, resulting in failure of electrical components such as relays and automatic control systems. At the same time, vibration inevitably produces noise, which affects the normal work of operators and even endangers healthy. In order to suppress the harmful vibration, people have carried out a lot of research for a long time. The active vibration absorber can generate the vibration damping force that offsets the exciting force in real time with the help of a cert...
