Description
Technical field
Mechanical connection field is the utility model is related to, is particularly flexible coupling.
Background technology
It is flexible coupling and is also known as flexibly connected, is a kind of equipment assembly and connection mode risen in recent years.Put in wood shavings board industry
Dynamic sieve is a kind of common equipment, because oscillating riddle needs to produce powerful exciting force drive screen box by vibrator at work
Vibrated with screen cloth, these strong vibrations will pass to and its body, cause it is certain rock and wear, while and oscillating riddle
If connected equipment is using Hard link meeting as being caused to produce collision by the vibration effect of oscillating riddle, so and oscillating riddle
Connected equipment must use be flexible coupling.
The soft even part device of oscillating riddle is flexible coupling using wear-resisting canvas more in existing wood shavings board industry, partly using PVC or
Silica gel is flexible coupling, and attachment means length is traditionally arranged to be 1.5 times of the diameter of itself, and service life is on 30W left side of vibration friction
The right side, about used 10 to 15 days for wood shavings board industry, therefore the life-span is very of short duration, causes use cost height, production efficiency by shadow
Ring, and maintenance operation is cumbersome.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of wood shavings board industry pendulum
Dynamic sieve soft connection device, it is flexible coupling the technical problem of short life for solving oscillating riddle in existing wood shavings board industry.
Technical scheme：To achieve the above object, the technical solution adopted in the utility model is：
A kind of wood shavings board industry oscillating riddle soft connection device, including the PVC bellowss with inside and outside double-layer structure, it is described
The centre of double-layer structure is provided with steel wire inside and outside PVC bellowss, and the steel wire has that identical is multiple, and according to PVC bellowss
It is evenly arranged centered on central shaft, ripple bending of the every steel wire along PVC bellowss is moved towards to bend and extend to PVC bellowss
Both ends.
The PVC bellowss of said structure have inside and outside double-layer structure, and centre is provided with steel wire, and steel wire is according to bellows
Ripple bending is moved towards to carry out bending, and because steel wire has certain rigidity, therefore the steel wire so after bending forms spring-like
Effect, there is provided very big buffering, reduce vibration, reduction is flexible coupling itself friction between other equipment.
Further, in order to which soft connection device and equipment to be connected are attached, the both ends bag of the PVC bellowss
Smooth straight-tube portion and the circle projection positioned at straight-tube portion termination periphery are included, the straight-tube portion is configured with locking strap.Institute
State straight-tube portion to be mutually socketed with equipment to be connected, then locked using locking strap.
Further, it is contemplated that need to reserve a fixed gap, and steel wire rigidity if diameter is too big between steel wire and ectonexine
Excessive not have the slow effect shaken, steel wire rigidity if diameter is too small is too small, does not have supporting role, therefore set the PVC
Between the ectonexine of bellows at intervals of 3mm~5mm, the gauge of wire is 1.8mm~2.3mm.
Further, the length of bellows is also to influence a key factor in its life-span, oversize to cause to be flexible coupling certainly
Body produces friction, and too short then stress is too big, it is oversize or it is too short can all influence the life-span, therefore the PVC bellowss are set
It is PVC inside diameter of bel that length D=kd+L, wherein k, which take 1.1~1.3, d, and L is 90mm~110mm.Obtain in the manner described above
Be flexible coupling and can bear vibration in use and reach 400W times or so, the use of number of days is about 150 days in wood shavings board industry
~180 days, the life-span increased substantially.
Beneficial effect：
Wood shavings board industry oscillating riddle provided by the utility model is flexible coupling utilize inside and outside two layers bellows and middle steel wire
A kind of new flexible connection structure is formed, this structure, which has to delay, is shaken, rubs the characteristics of small so that the longevity is used in wood shavings board industry
Life reaches or so half a year, avoids regular replacing and is flexible coupling the manpower brought, financial resources and leeway, improves production
Efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional drawings in Fig. 1.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
A kind of wood shavings board industry oscillating riddle soft connection device as shown in Figure 1, including the PVC ripples with inside and outside double-layer structure
Line pipe 1, between the ectonexine of the PVC bellowss 1 at intervals of 4mm, the centre of double-layer structure inside and outside the PVC bellowss 1
Steel wire 5 is provided with, as shown in Fig. 2 inside and outside a diameter of 2mm of the steel wire 5, steel wire 5 and PVC bellowss 1 between double-layer structure
A fixed gap is respectively provided with, the steel wire 5 has identical 4, and is evenly arranged centered on the central shaft according to PVC bellowss 1, often
Bending of the root steel wire 5 along PVC bellowss 1 is moved towards to bend and extend to the both ends of PVC bellowss 1.
The both ends of the PVC bellowss 1 include smooth straight-tube portion and enclosed positioned at the one of straight-tube portion termination periphery convex
2 are played, the straight-tube portion is configured with locking strap 4.
It is the internal diameter of PVC bellowss 1 that the length D=kd+L of PVC bellowss 1, wherein k, which take 1.2, d, L 100mm.
Oscillating riddle screens wood shavings, and needs, by wood shavings input mixer progress and the mixing of glue, now to pass through this
The discharging opening with oscillating riddle, the charging aperture of mixer are connected the straight-tube portion at device both ends respectively, then are locked respectively with locking strap 4
So that connection is reliable.The wood shavings filtered out are continually by being flexible coupling into mixer, and the vibration of oscillating riddle is to mixer
It is small with the influence that is flexible coupling.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
