Abstract
An elastic vibration-damping chain wheel structure comprises a chain wheel, an elastic ring, a winding spring, a support ring and a rivet. The support ring is connected to the chain wheel through the rivet, the step outer ring of the support ring is provided with the winding spring, the elastic ring is arranged outside the winding spring in a floating support mode, the outside of the support ring and the inside of the elastic ring are both provided with flanges which are used for axially limiting the winding spring, and the outer diameter of the elastic ring is larger than the radius of an envelope circle which is formed inside a chain plate when a chain envelopes the chain wheel. When the chain is engaged with the chain wheel, the elastic ring is compressed first to bear impact, the vibration generated by the impact is reduced due to the elastic deformation of the elastic ring and the yielding under the action of the winding spring, so that the service life of chain transmission is prolonged.
Description
Technical field
The utility model relates to a kind of elastic damping chain sprocket structure, belongs to the mechanical transmission controlling device, and the vibration damping that is mainly used in chain transmission middle sprocket is used.
Background technique
In the chain transmission, the engagement of chain and sprocket wheel is discontinuous contact movement, and chain can produce impact shock by the place, point of contact of straightway displacement arc section, and speed is more high, impact is more serious.
Summary of the invention
For reducing the impact shock that the chain transmission produces, the lift chain transmission speed, the utility model provides a kind of simple structure list, stable performance, wieldy elastic damping chain sprocket structure, reduces the impact that chain brings to sprocket wheel by the elastic damping circle is set at the chain wheel side.
The technical solution of the utility model is: be used for the elastic damping chain sprocket structure of chain transmission, comprise sprocket wheel, elastic ring, clockwork spring, bearing ring, rivet.Described bearing ring is connected on the sprocket wheel by rivet, at the step cylindrical device of bearing ring clockwork spring is arranged, the flexible circle of outside floating support of clockwork spring, and the outside of bearing ring, the inboard of elastic ring all have the rib to the clockwork spring axial limiting; The cylindrical of described elastic ring is the inboard envelope circle radius that forms of carrier bar during greater than chain envelope sprocket wheel, when chain and sprocket engagement, elastic ring at first contacts compression and withstands shocks, impact the vibration that produces because the resiliently deformable of elastic ring and dodging under the clockwork spring effect are reduced, improve chaindriven working life.
Description of drawings
Accompanying drawing 1 is the utility model 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 utility model 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 the sprocket wheel by rivet 5, step cylindrical device at bearing ring 4 has clockwork spring 3, the flexible circle 2 of the outside floating support of clockwork spring 3, the inboard of the outside of bearing ring 4, elastic ring 2 all has the rib to clockwork spring 3 axial limitings.
The cylindrical of the elastic ring 2 of described elastic damping chain sprocket structure is the inboard envelope circle radius that forms of carrier bar during greater than chain envelope sprocket wheel, when chain and sprocket wheel 1 engagement, elastic ring 2 at first contacts compression and withstands shocks, because the resiliently deformable of elastic ring 2 and dodging under clockwork spring 3 effects are reduced the vibration of impacting generation, improve chaindriven working life.
