Abstract

The utility model discloses a disc spring's buffer gear, including atress pole and protecting sheathing, protecting sheathing upper portion is provided with belleville spring, the atress pole runs through belleville spring, atress pole bottom is provided with and is used for spacing stop gear. In the utility model, under the pushing of external force, the stress rod extrudes the disc spring, and the disc spring is pressed to generate elastic force and damping force; when the buffer is free from external acting force, the buffer is quickly and automatically reset; the disk spring has the advantages that the disk spring can generate large-tonnage buffering force by small displacement and has large damping.

Description

Buffer mechanism of belleville spring

Technical Field

The utility model relates to a buffer gear technical field that mechanical equipment used specifically is a disc spring's buffer gear.

Background

The shock absorber is an important component of various mechanical devices, and is a necessary device for absorbing impact energy and mitigating unnecessary impact.

For some large-scale mechanical equipment, when vibration in the gravity direction needs to be weakened, the vertical bearing capacity of the buffer is required to be large; due to space constraints, the buffer volume is required to be small. The ring spring is the primary damping device. The annular spring is difficult to generate larger buffer force under small displacement, larger displacement is required to generate large-tonnage buffer force, and the diameter of the annular spring is larger, so that the annular spring is large in size and occupies larger use space; in addition, the damping of the annular spring is small, so that the damping effect is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a belleville spring's buffer gear to solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a butterfly spring's buffer gear, includes atress pole and protecting sheathing, protecting sheathing upper portion is provided with belleville spring, the atress pole runs through belleville spring, the atress pole bottom is provided with and is used for spacing stop gear.

Preferably, the limiting mechanism consists of a gasket and a bolt, and the gasket is fixed at the bottom end of the stress rod through the bolt.

Preferably, the protective housing is mounted on the device.

Compared with the prior art, the beneficial effects of the utility model are that: under the pushing of external force, the stress rod extrudes the disk spring, and the disk spring is pressed to generate elastic force and damping force; when the buffer is free from external acting force, the buffer is quickly and automatically reset; the disk spring has the advantages that the disk spring can generate large-tonnage buffer force with small displacement and large damping.
