Embodiment 1

[0039] like Figure 1-6 As shown, the present invention provides a ratchet rack container based on a reducer, which has a single-layer frame structure 8, and two racks 1 are respectively arranged on the lower surface of the frame top plate along the length direction of the single-layer frame structure 8 On both sides, and the teeth of the rack 1 face downward, and are riveted to the top plate by bolts at the same time, and a spring is arranged outside the bolt to form a bolt spring 6 to automatically adjust the distance between the rack 1 and the top plate. Fixed on the upper surface of the bottom plate of the frame, the inerter includes: two gears 2, the gears 2 are respectively meshed with two racks 1 for transmission, and are fixedly equipped with one-way toggle claws, and the claws are accompanied by the gears 2 Rotation; two ratchets 3, the ratchets 3 are respectively arranged on the outer side of the single-layer frame structure 8 than the two gears 2, and are engaged wi...

Abstract

The invention provides a ratchet wheel rack inerter based on a speed reducer. The ratchet wheel rack inerter is provided with racks, gears, ratchet wheels, the speed reducer and fly wheels, wherein each gear is engaged with the corresponding rack; each ratchet wheel is engaged with the corresponding gear; the speed reducer is engaged with the ratchet wheels; and each fly wheel is engaged with thecorresponding speed reducer. The gears are fixedly provided with hook claws which are shifted in the single direction so that the rotation direction of the ratchet wheels can be limited. The two corresponding ratchet wheels and the two corresponding hook claws are opposite to each other in mounting direction. Horizontal motion in the left-right direction can be sequentially converted into clockwise rotation and counterclockwise rotation of the two fly wheels, and thus, the large rotation inertia can be achieved; the adverse driving effect of the gears on the structure is avoided; and the deceleration process, from a instant extreme value to zero, of the structure is accelerated; and in addition, the resonance response can be reduced.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a gear-and-rack inerter based on a speed reducer. Background technique [0002] In the field of civil engineering structures, in addition to natural factors such as earthquakes, wind vibrations, and waves, the sources of vibration also include human factors such as transportation, machine operation, and construction blasting. Although the sources of various dynamic loads are different, the damage to civil engineering structures cannot be underestimated. For example, for earthquakes, the natural disaster with the widest impact, major earthquakes will cause house collapse, bridge breakage, casualties, and minor earthquakes will also cause cracking and deformation of buildings and damage to non-structural components, reducing the sense of security and comfort of use. Spend. Regardless of the magnitude of the earthquake, the vibration of civil structures seriously th...
