Description
Technical field
The present invention relates to a kind of drive system, particularly a kind of chain drive system.
Background technology
Existing bushroller chain includes drive sprocket, driven sprocket and chain, chain is made up of inner plate, outer plate, sleeve, bearing pin, roller, outer plate is fixed on bearing pin, inner plate is fixed on sleeve, being respectively formed coaxial rotating attachment structure between roller and sleeve and between sleeve with bearing pin, chain forms rolling friction with sprocket wheel and is connected, thus bushroller chain is lightweight, life-span length, low cost, therefore, bushroller chain is widely used in existing motorcycle, electric motor car and bicycle.But the chain part quantity of this drive mechanism is many, and running noises is big.And more prominent be that sprocket wheel needs special equipment and dedicated tool processing, and the intensity of the chain toothed portion of sprocket wheel and wearability require height, and the corresponding material manufactured and heat treatment requirements are high, and sprocket is difficult to repair after damaging, and cause manufacturing cost and use cost high.For this reason, it may be necessary to existing chain drive system is improved.
Summary of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art, a kind of chain drive system is provided, this system uses profile of tooth chain and the sprocket wheel of roller type sprocket, thus simplify the number of parts of drive system structure, reduce fretting wear and the power consumption of drive system, and reduce manufacture difficulty, and manufacturing cost and use cost.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of chain drive system, including drive sprocket, driven sprocket and the chain of ring seal structure, the endoporus of drive sprocket is splined hole structure, and it is the most interlaced hinged by bearing pin that chain is made up of internal messing silent chain, the first chain link and the second chain link the first chain link, the second chain link and bearing pin；Described drive sprocket and driven sprocket all include two end face disks, two end face disks are connected by the middle connecting cylinder at middle part, between two end face disks of middle connecting cylinder periphery, it is evenly distributed in the roller of multiple composition sprocket, and described internal messing silent chain also is formed to break away and limits by two end face disks.
Use the present invention of preceding solution, owing to chain is constituted internal messing silent chain by the first chain link, the second chain link and bearing pin, and drive sprocket and driven sprocket all consist of the sprocket of respective sprockets roller, roller is used to substitute the sprocket of the synchronous sprocket wheel in conventional synchronization silent chain transmission；It has not only played conventional synchronization silent chain stable movement, the low advantage of noise, simultaneously, sliding friction between chain with sprocket wheel is connected and is converted into rolling friction connection, thus effectively reduce and synchronize chaindriven fretting wear and the kinetic equation loss of frictional resistance, improve transmission efficiency, on the premise of same chain intensity, improve chain bearing capacity.It can be used for electric motor car, motorcycle, bicycle and electromotor, to replace existing bushroller chain, to synchronize chain or Synchronizable drive systems.The more important thing is, roller can be changed after damaging easily, does not results in sprocket wheel entirety and scraps.Additionally, owing to sprocket wheel forms wire rewinding disc structure by two end face disks and middle connecting cylinder, the sideslip of silent chain is formed and limits by the forward surface of two end face disks, it is not required to arrange guide plate on silent chain, thus compact chain structure, decrease taking up room of drive system, be beneficial to arrange on vehicle.More simpler than existing synchronization chain drive structure.Two end face disks of sprocket wheel and middle connecting cylinder can be by casting, forging or be welded into overall structure, also can pass through flat key, spline, bolt or axis hole tight fit connection and form combinative structure, its structure is formed flexibly, situation can be selected to determine according to concrete manufacturing process or material, wherein, when using flat key, spline or axis hole tight fit connection structure, end face disk is sleeved on middle connecting cylinder.
Preferably, described first chain link is stacked by 2～3 chain tablet weights；Described second chain link is made up of two the chain sheets laying respectively at described first chain link both sides.To simplify structure, improve efficiency of assembling；And chain is only made up of chain sheet and bearing pin, it is effectively reduced number of parts, improves production efficiency, reduce manufacturing cost.Even if the material that the chain sheet in the first chain link and the second chain link uses different-thickness makes, both has same cross-sectional, can use same blanking die stamping-out.
Preferably, described drive sprocket and driven sprocket, all in dismountable combinative structure, connect by least two articulation bolt is fixing between end face disk and middle connecting cylinder.Reduce sprocket wheel difficulty of processing, reduce manufacturing cost.Wherein, articulation bolt can a corresponding independent end face disk and being connected with middle connecting cylinder, it is possible to connected by two end face disks by articulation bolt, and centre connecting cylinder plays spacer effect.
Preferably, described splined hole runs through and constitutes the described middle connecting cylinder of described drive sprocket and two described end face disks.To guarantee between middle connecting cylinder and two end face disks without rotating dislocation, improve sprocket wheel rigidity and intensity, and then improve service life.
Preferably, the medial surface outward flange of described end face disk is formed with guiding surface.To guarantee that chain enters or exit sprocket wheel smoothly, reduce running resistance, improve transmission efficiency.
Preferably, the rotating sleeve that is lined with of described roller, sleeve set is on roller bearing, and roller bearing two ends are separately fixed on two described end face disks.To form, by sleeve and roller bearing, the combinative structure that roller supports, in order to after sleeve wears away, increase the service life by the way of only changing sleeve, and reduce use cost.
Preferably, said two end face disk is by forming the restriction of the sideslip to described internal messing silent chain to axially limiting of described bearing pin.To be formed the lateral register of chain by the fit structure of bearing pin and two end face disks, chain is not required to arrange guide plate, and sprocket wheel is without additionally arranging special guide frame, to simplify structure further, reduces manufacturing cost, and improves the convenience safeguarded and keep in repair.
It is further preferred that the gap summation between the two ends of described bearing pin length and two end face disks is 1.0～5.0mm.With by rational gap width, it is ensured that chain operates steadily, smooth and easy, without card group, and reduce the frictional resistance between chain and sprocket wheel and abrasion.
It is further preferred that described bearing pin head is circular arc or has the guiding conical surface.With guarantee in terms of planform chain operate steadily, smooth and easy, without card group, and reduce the frictional resistance between chain and sprocket wheel and abrasion.
Experiments verify that, the chain drive system of the present invention is compared with the Roller Chain Drive system of traditional structure, in the case of pitch is identical with outer chain sheet thickness, its load capacity can improve 10～30%, under the same load, its life-span can improve nearly 50%, and manufacturing cost can reduce nearly 30%.
The invention has the beneficial effects as follows, by the sprocket wheel in the toothed synchronous chain drive structure of traditional structure is improved so that it is form rolling friction fit structure with chain, reduce frictional resistance and noise, improve transmission efficiency；And simple in construction, manufacture difficulty are low, manufacturing cost and use cost is low.
