Description
Technical field
The present invention relates to gearing fields, more particularly to a kind of transmission chain and use the variable speed of the transmission chain
Device.
Background technique
The transmission chain of existing chain structure, be substantially all to be bent in deformation in a plane, due to shaking in practice,
The a variety of causes such as inertia and torsional deformation can make transmission chain stress in the direction of the width, in a tensioned state, because length is closed
Reasons, the transmission chain such as system and friction are difficult to reduce or eliminate this power bending by the displacement of width direction, are bent
Variable curvature distribution afterwards, which can make to pull to load, to be focused on edge and increased dramatically, and the state of this discontinuity is easy to
It causes locally to overload and destroy hinged characteristic, therefore the transmission chain of existing chain structure, it is virtually impossible to stress in the direction of the width,
If the benchmark sagittal plane of two driving wheels is not in the same plane when being especially driven, transmission chain can be twisted and persistently by
Injury.
Summary of the invention
In view of the deficiencies of the prior art, it the object of the present invention is to provide a kind of transmission chain, increases in the direction of the width
Deformability, to improve use reliability and durability.
The purpose of transmission chain of the present invention is achieved in that a kind of transmission chain, is connected by the excessively multiple connecting rods of multiple links
Constitute, some or all of connection chain link connecting rod is jointed connecting rod, jointed connecting rod include there are two hinged seat, two hinged seats it
Between be hinged with waling stripe, hinged seat is equipped with fraising and is used for connection chain link.
Based on the above technical solution, there are also following preferred embodiments for transmission chain of the invention:
Chain link on transmission chain is partly or entirely twin shaft chain link, and twin shaft chain link includes two pin shafts, two pin shafts it
Between be connected with pulling plate, pin shaft both ends are fixed with axle cap.
Hinged seat is equipped with hinge post, passes through the hinged waling stripe of hinge post, hinge post axis and fraising axis between two hinged seats
Line is non-intersecting.
The inclined-plane with pin shaft axis out of plumb is equipped on the outside of axle cap.
The purpose of stepless transmission of the present invention is achieved in that a kind of stepless transmission, uses above-mentioned transmission chain.
Detailed description of the invention
Fig. 1, Fig. 2 are the structural schematic diagrams of chain link different embodiments in the present invention；
Fig. 3 is the structural schematic diagram of jointed connecting rod in the present invention；
Fig. 4 is the partial structure diagram of transmission chain of the present invention.
Specific embodiment
The embodiment of transmission chain of the present invention is described in detail with reference to the accompanying drawing:
Transmission chain of the invention is connected and composed by the excessively multiple connecting rods of multiple links, and some or all of connection chain link is even
Bar is jointed connecting rod, and jointed connecting rod includes being hinged with waling stripe 7, hinged seat 5 between two hinged seats 5 there are two hinged seat 5
It is equipped with fraising 8 and is used for connection chain link.It is the basic of chain structure that transmission chain is connected and composed by the excessively multiple connecting rods of multiple links
Feature, the transmission chain in the present invention, chain link can be used existing structure, Fig. 1, structure shown in Fig. 2, i.e. chain link also can be used
For twin shaft chain link, connected and composed by the fixed axle cap 2 of two pin shafts 1 and both ends, pulling plate 3 is cased between pin shaft 1 can increase tension
Intensity；In Fig. 1, each axle cap 2 connects two pin shafts 1, there is 4 axle caps 2 in Fig. 2, and every pin shaft 1 individually connects two axle caps 2,
The characteristics of Fig. 2 structure is that axle cap 2 can rotate freely, and when transmission can improve the way of contact of transmission chain and driving wheel, to prevent
Inordinate rotation, can connecting spring isoequilibrium mechanism between axle cap 2.Referring to Fig. 3, jointed connecting rod includes that there are two hinged seats 5, hingedly
About 5 seat is fixed there are two hinge post 6, between two hinged seats 5 by hinge post 6 it is hinged there are two waling stripe 7, to prevent level
Connecting rod 7 separates, and can limit with Sheet Metal Forming Technology or using components such as snap ring, fastening tablettings after hinged, hinged seat 5 is equipped with hinge
Hole 8 is for the pin shaft 1 on articulated links.When the chain link and multiple jointed connecting rods shown in Fig. 3 that use type shown in multiple Fig. 2 connect
After connecing, that is, a kind of transmission chain shown in Fig. 4 is constituted, due to the two-way hinged effect of jointed connecting rod, chain link in Fig. 4 not only can be with
Rotation, moreover it is possible to move in the direction of the width.
Had as described below according to embodiment described above:
1. can be connected between the chain link of part using combination when the displacement that transmission chain needs in the direction of the width is smaller
Prior art construction also can be used in bar connection, chain link.
2. the pulling plate 3 connected between pin shaft 1 can also be substituted with jointed connecting rod, such a twin shaft chain link in shown in Fig. 2
It is turned into two uniaxial chain links, but after this structure is configured to transmission chain, obvious advantage will not be brought, make the width of transmission chain instead
Degree increases many.
It is the embodiment explanation of transmission chain preferred embodiment of the present invention below:
Chain link on transmission chain is partly or entirely twin shaft chain link, and twin shaft chain link includes two pin shafts 1, two pin shafts 1
Between be connected with pulling plate 3,1 both ends of pin shaft are fixed with axle cap 2.Structure i.e. shown in fig. 1 or fig. 2, is this hair using twin shaft chain link
The embodiment that bright transmission chain is recommended.
Hinged seat 5 is equipped with hinge post 6, by the hinged waling stripe 7 of hinge post 6 between two hinged seats 5,6 axis of hinge post and
8 axis that ream are non-intersecting.See Fig. 3,6 axis of hinge post and the disjoint effect of 8 axis of fraising are to shorten the length of waling stripe 7,
To guarantee that transmission chain has enough bending angle.
The inclined-plane 4 with 1 axis out of plumb of pin shaft is equipped on the outside of axle cap 2.See Fig. 2, inclined-plane 4 can be with existing stepless transmission
In cone pulley face cooperation constitute transmission.My earlier application has ' a kind of diameter-changing wheel and transmission chain ', have on the outside of axle cap 2 plane with
When 1 axis of pin shaft is vertical, it can cooperate with diameter-changing wheel and constitute transmission.
It is the embodiment explanation of stepless transmission of the present invention below:
A kind of stepless transmission uses above-mentioned transmission chain.Transmission chain of the invention and prior art comparison, the main distinction
It is that the connection type between chain link is different, does not interfere with the Contact Transmission between chain link and driving wheel, so can be used in existing
Have on stepless transmission, since the basic structure of this speed changer is well-known technique or common sense, therefore stepless transmission of the invention,
Specific structure repeats no more.
Transmission chain of the invention, by the effect of jointed connecting rod can deformation stress in the direction of the width, therefore be regarded as one
Kind of three-dimensional structure, in contrast to existing two-dimensional structure, advantage is that distribution of force is uniform after improving deformability, be conducive to reduce or
The disadvantage of existing structure ' excessively just easy to break ' is avoided, to reduce the technical requirements of transmission chain, increases reliability and durability.This hair
Bright transmission chain optimum is on stepless transmission.
