Abstract
One kind may reduce the impact to reduce the noise the chain wheel structure, involves the mechanical drive area of technology. It including the chain wheel and the gland, gets up the unique feature is. It also includes the elastic pad, states the elastic pad to inlay installs among the chain wheel and the gland, the elastic pad outer diameter is bigger than the chain wheel the root circle diameter, compares with the existing technology, this invention in does not change the chain wheel material and in the structure situation, can obviously reduce chain drive the time noise, the increase chain drive stability, also practical is widespread.
Description
Technical field
The present invention relates to the mechanical transmissioning technology field, particularly can reduce and impact the chain sprocket structure that reduces noise.
Technical background
Chain-driven is the wider mechanical transmission component of a kind of application, it have velocity ratio accurately, characteristics such as reliable operation, transmission efficiency height, transmission centre distance using scope be big, be widely used in the various machinery such as agricultural, mining, metallurgy, oil, chemical industry, lifting and transportation.Chain sprocket structure has integrated type, articulated etc.In the engagement process of sprocket wheel and chain, since the influence of chain-driven polygon effect, chain link of driving wheel revolution, and the instantaneous velocity of chain periodically changes from small to big, and changes once from large to small again.In this periodic variation, the chain and the gear teeth can produce a dynamic load that is caused by impact.Teeth number of sprocket is few more, changes more greatly with the instantaneous velocity of chain in the cycle, and dynamic load is big more, and for rigidity chain and sprocket wheel, impact noise is also big more, and simultaneously, dynamic load has been quickened the fatigue ruption of chain.In order to overcome these defectives, prior art is normally increasing teeth number of sprocket, or reduces motion speed and reduce noise, but this can limit chaindriven application.Carry the apron conveyor that uses as logistics, because the restriction of spatial structure and load, the chain number of teeth is too much unsuitable, and speed chain can not surpass 12 meters/minute usually, otherwise can cause intense noise.In the practical application, also have with fabroil to replace metallic material to make sprocket wheel with the reduction noise, but because the epistasis degree of fabroil is low, and when work, environmental conditionss such as temperature are had relatively high expectations, use is restricted.
Summary of the invention
At the problem that above-mentioned prior art exists, the purpose of this invention is to provide a kind of the minimizing and impact the chain sprocket structure that reduces noise.It can significantly reduce the impact of chain and sprocket wheel, when reducing noise, improves the stationarity of transmission, and chain is prolonged working life.
In order to reach above-mentioned goal of the invention, technological scheme of the present invention realizes as follows:
A kind of chain sprocket structure that impact to reduce noise that reduces, it comprises sprocket wheel and gland, and its structural feature is, and it also comprises cushion, and described cushion is inlaid in the middle of sprocket wheel and the gland, and the external diameter of cushion is greater than the root diameter of sprocket wheel.
According to above-mentioned technological scheme, described sprocket wheel can adopt integrated type, orifice-plate type or articulated.
According to above-mentioned technological scheme, described cushion can be arranged on the both sides of sprocket wheel or one-sided.
According to above-mentioned technological scheme, described cushion can be made into integrated type or combined type.
According to above-mentioned technological scheme, the profile of described cushion can be ring or sprocket annular.
The direct impact of sprocket wheel and chain has been avoided in the use of cushion among the present invention, and cushion has installation easily, cheap characteristics.Compare with prior art, the present invention is under the situation that does not change sprocket wheel material and structure, and the noise in the time of obviously reducing chain-driven increases chaindriven stationarity, and widely applicable.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the axial schematic representation of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the present invention includes sprocket wheel 1, gland 3 and cushion 2.Described cushion 2 is inlaid in the middle of sprocket wheel 1 and the gland 3, and the external diameter of cushion 2 is greater than the root diameter of sprocket wheel 1.Its middle sprocket 1 can adopt integrated type, orifice-plate type or articulated.The profile of cushion 2 can be ring or sprocket annular, and its structure can be made integrated type or combined type, can also select its both sides or one-sided fixed installation at sprocket wheel 1 simultaneously.
The present invention in actual applications, when chain link 4 meshes with sprocket wheel 1, at tooth root place near sprocket wheel 1, what chain link 4 at first touched is cushion 2, in the process of cushion 2 extrusion-deformations, it has absorbed the impact force of chain link 4 with sprocket wheel 1, and dynamic load is reduced, slowed down fatigue ruption on the one hand, reduced rotational noise on the other hand chain.
