Abstract

An elastic vibration attenuation chain wheel structure comprises a chain wheel, an elastic ring, a power spring, a supporting ring and a rivet, wherein the support ring is connected with the chain wheel through the rivet, the power spring is arranged on an outer circle of a step of the support ring, the elastic ring is supported on the outer side of the power spring in a floating mode, the outer side of the support ring and the inner side of the elastic ring are provided with blocking edges for axially limiting the power spring, and the radius of the outer circle of the elastic ring is larger than the radius of an enveloping circle formed by the inner side of a chain plate when the chain envelopes the chain wheel. When the chain is meshed with the chain wheel, the elastic ring is firstly subjected to contact compression to bear shock; due to elastic deformation of the elastic ring and escapement of the elastic ring under the function of the power spring, vibration produced by the shock is reduced, and service life of chain transmission is prolonged.

Description

Elastic damping chain sprocket structure
Technical field
The invention relates to a kind of elastic damping chain sprocket structure, belongs to mechanical transmission controlling device, is mainly used in the vibration damping application of chain transmission middle sprocket.
Background technique
In chain transmission, chain is discontinuous contact movement with engaging of sprocket wheel, and chain can produce impact shock by the point of contact place of straightway displacement arc section, and speed is higher, impact is more serious.
Summary of the invention
The impact shock producing for reducing chain transmission, lift chain transmission speed, the invention provides a kind of simple structure list, stable performance, wieldy elastic damping chain sprocket structure, reduces by elastic damping circle is set at chain wheel side the impact that chain brings to sprocket wheel.
The technological scheme of the invention is: for the elastic damping chain sprocket structure of chain transmission, comprise sprocket wheel, elastic ring, clockwork spring, bearing ring, rivet.Described bearing ring is by rivet joint on sprocket wheel, and on the step cylindrical of bearing ring, device has clockwork spring, the flexible circle of outside floating support of clockwork spring, and the outside of bearing ring, the inner side of elastic ring are all with the rib to clockwork spring axial limiting; The envelope circle radius that when cylindrical of described elastic ring is greater than chain envelope sprocket wheel, carrier bar inner side forms, when chain and sprocket engagement, first elastic ring contacts compression and withstands shocks, due to the resiliently deformable of elastic ring and the vibration that dodging reduction impact generation under clockwork spring effect, improve chaindriven working life.
Brief description of the drawings
Accompanying drawing 1 is the invention elastic damping chain sprocket structure cut-away illustration, and accompanying drawing 2 is elastic damping chain sprocket structure figure.
Embodiment
Referring to accompanying drawing, the invention provides a kind of elastic damping chain sprocket structure, comprises sprocket wheel 1, elastic ring 2, clockwork spring 3, bearing ring 4, rivet 5.
The bearing ring 4 of described elastic damping chain sprocket structure is connected on sprocket wheel by rivet 5, on the step cylindrical of bearing ring 4, device has clockwork spring 3, the flexible circle 2 of outside floating support of clockwork spring 3, the outside of bearing ring 4, the inner side of elastic ring 2 are all with the rib to clockwork spring 3 axial limitings.
The envelope circle radius that when cylindrical of the elastic ring 2 of described elastic damping chain sprocket structure is greater than chain envelope sprocket wheel, carrier bar inner side forms, when chain engages with sprocket wheel 1, first elastic ring 2 contacts compression and withstands shocks, due to the resiliently deformable of elastic ring 2 and the vibration that dodging reduction impact generation under clockwork spring 3 effects, improve chaindriven working life.
