Embodiment 1

[0034] Such as Figure 1-6 As shown, a double-rack driven rotary square inner grooved gear lead damper of the present invention includes a connecting baffle plate 1, a front side plate 2, a rear side plate 3, an upper rack 4, a lower rack 5 and a gear device . Connect the baffle plate 1, the front side plate 2, and the rear side plate 3 to form a cavity, and the upper rack 4 and the lower rack 5 respectively penetrate the gap formed by the front side plate 2 and the rear side plate 3 from opposite ends And pass through the groove on the connecting baffle 1, and then pass out from the other end, and the upper rack 4 and the lower rack 5 are always in clearance fit with the groove on the connecting baffle 1. The upper rack 4 and the lower rack 5 also mesh with the gear device inside the cavity. The gear device includes an inner square groove gear 6 , a spline shaft 7 and a flange 8 . The spline shaft 7 is placed at the center of the inner square grooved gear 6, and the two en...

Embodiment 2

[0037] Such as Figure 7-9 As shown, another embodiment of the double-rack driven rotary square internal groove gear lead damper of the present invention, wherein the parts without teeth of the upper rack 4 and the lower rack 5 are cylinders, and the cylinders go deep into the other end Inside the sleeve welded to the end plate, the diameter of the cylinder is slightly smaller than the diameter of the sleeve. Other components and connection methods are the same as in Embodiment 1.

Abstract

The invention relates to a double-rack driven lead damper provided with a rotary gear with inner square slots. The lead damper comprises a cavity, racks, the gear with the inner square slots, a spline shaft, a flange and the like, wherein the spline shaft is arranged at the center of the gear with the inner square slots, and spline slots are formed in a spline shaft body; the flange is welded and sealed at the front end of the gear with the inner square slots; lead is poured into a gap between the spline shaft and the gear with the inner square slots through hole communicating the spline shaft and the spline slots; the front end and the rear end, extending out of the gear with the inner square slots, of the spline shaft are welded on a front side plate and a rear side plate. When the upper rack and the lower rack perform stretching and reciprocating motion, the upper and lower racks and teeth of the gear with the inner square slots are meshed for transmission, the gear with the inner square slots is driven to rotate, lead between the gear with the inner square slots and the spline shaft is driven to realize plastic deformation through reciprocating rotation of the gear with the inner square slots, and accordingly, the energy is dissipated.

Description

technical field [0001] The invention relates to a gear transmission damper, in particular to a double rack-driven rotary square inner groove gear lead damper, which can be applied to the vibration reduction control of building structures and belongs to the technical field of vibration control. Background technique [0002] Lead damper is a kind of control device that uses the plastic deformation of lead to dissipate vibration energy. It has superior hysteresis performance, simple structure and convenient manufacture. It is used as an energy-dissipating device in energy-dissipating and shock-absorbing buildings. [0003] The lead damper was first developed by New Zealand Penguin Engineering Company, and then RobinsonSeismoc Ltd developed two similar lead dampers: Penguin Vibration Damper (PVD) and Robinson Vibration Damper (RVD). They all use lead to dissipate energy by plastic deformation after shear yielding. The advantages of the damper made of lead material mainly inclu...
