Description
Technical field
The present invention relates to a kind of four-bar mechanism shaft coupling.
Background technology
Conventional shaft coupling is divided into following a few classes：1st, cross coupler.Be mainly used in decelerator low speed shaft end and wheel or
Connection between reel, its major advantage be it is simple in construction, it is easily manufactured, larger moment of torsion can be transmitted, have the disadvantage that compensation rate is small,
It is required that installation accuracy is higher.2nd, gear coupling.Gear coupling is each motion of crane using at most compensation
Shaft coupling, point with Full-gear coupler and half a coupler, its advantage is that appearance and size is small, and transmitting torque is big, it is allowed to be connected
Axle between have larger offset, to installation accuracy require relatively low, reliable operation.Have the disadvantage that manufacturing process is complicated, cost compared with
It is high.3rd, elastic dowel pin shaft coupling.Elastic dowel pin shaft coupling has rubber ring pin coupler and nylon ring pin coupler.Its is excellent
Point is simple in construction, energy buffer shock-absorbing, it is not necessary to lubricate, it has the disadvantage that transmitting torque is small, elastic ring is easy to wear, the life-span is low.Adopt
It is better than caoutchouc elasticity circle with nylon elastic circle, service life has been greatly improved, and be simple to manufacture, repair, change easily.With
The structure of these upper shaft couplings is more complicated, is more expensive to manufacture.Therefore need to study a kind of reliable and stable, simple in construction, manufacture
Convenient four-bar mechanism shaft coupling.
The content of the invention
The present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the technical problems to be solved by the invention are
A kind of four-bar mechanism shaft coupling is provided, makes simple, repair demolition is easy, reliable operation.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of four-bar mechanism shaft coupling, including respectively with
Rigidly connected first crank of two axles and the second crank, it is in Z-shaped that two are hinged between first crank and the second crank
The first connecting rod and second connecting rod of shape；The first connecting rod includes the first transverse arm that one end is hinged with first crank one end, the
The other end of one transverse arm is connected with the first montant, and the other end of the first montant is connected with the second transverse arm, the other end of the second transverse arm
It is hinged with one end of the second crank；The second connecting rod includes the 3rd transverse arm that one end is hinged with the first crank other end,
The other end of 3rd transverse arm is connected with the second montant, and the other end of the second montant is connected with the 4th transverse arm, the 4th transverse arm it is another
The other end with the second crank is held to be hinged；The length of first transverse arm is longer than the 3rd transverse arm, and the length of the second transverse arm compares
Four transverse arms are short, and during so as to rotate, the transverse arm of two connecting rods, which to be staggered, do not interfere.
Compared with prior art, the invention has the advantages that：The present apparatus is simple in construction, easy to process, easily peace
Dress, stable and reliable operation can be used for transmission motion and power between parallel axes.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the organigram of the embodiment of the present invention.
In figure：1- first axis, the cranks of 2- first, the cranks of 3- second, the transverse arms of 4- first, the montants of 5- first, 6- second is horizontal
Arm, the montants of 7- second, the transverse arms of 8- the 4th, second axle of 9-.
Embodiment
Embodiment one：As shown in figure 1, a kind of four-bar mechanism shaft coupling, including respectively with two axles（1、9）It is rigidly connected
Two first connecting rods in zigzag are hinged between first crank 2 and the second crank 3, the crank 3 of the first crank 2 and second
And second connecting rod；The first connecting rod includes the first transverse arm 4 that one end and first crank one end are hinged, the first transverse arm it is another
End is connected with the first montant 5, and the other end of the first montant is connected with the second transverse arm 6（Second transverse arm 6 can shorten to hinge）, the
One end of the other end of two transverse arms and the second crank 3 is hinged；The second connecting rod includes one end and the first crank other end phase
The 3rd transverse arm being hinged（This 3rd transverse arm shorten to hinge）, the other end of the 3rd transverse arm is connected with the second montant 7, the second montant
The other end be connected with the 4th transverse arm 8, the other end of the other end and the second crank of the 4th transverse arm is hinged；First transverse arm
Length it is longer than the 3rd transverse arm, the length of the second transverse arm is shorter than the 4th transverse arm so that rotate when, the transverse arm of two connecting rods staggers not
Interference.
When first axis 1 is rotated, the first crank 2 is driven to rotate, the two connecting rods rotations of the first crank 2 and then drive, two
Individual connecting rod drives the rotation of the second crank, and the second axle 9 of crank handle turns second rotates.First axis 1 and second axle 9 can be wrong
The parallel axes or the axle with center line opened.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modification, should all belong to the covering scope of the present invention.
