Dynamic position.
The present embodiment, can simultaneously be driven, i.e. the soft transmission of multiple spot chain by multiple sprocket for main drive 13, whole transmission devices or
Part low speed gear stage suspension is installed on support 1；Its low speed machine floating arm 11 passes through the second accumulator 4, i.e. spring
The axle of bearing up pulley 3 that risen again after damping is fixed；So the advantage of multiple spot chain Flexible Transmission is：Suspension is installed and float support；Chain 8 is all the time
Keep being adjacent to the excircle of passive tooth plate 2, no matter passive tooth plate 2 how to be deformed or the passive center of tooth plate 2 of mounting and adjusting occurs partially
Move, can guarantee that chain 8 is engaged well.
1st, transmission performance is good：Using flexible drawing, during driving, countertorque be applied to simultaneously it is outside upper make flexible piece produce change
Shape, absorbs kinetic energy, and when the countertorque equal to driving torque is more than the smart moment of resistance, the axle of sprocket for main drive 13 just starts rotation.System
When dynamic, torque is also gradually changed, therefore reduces dynamic loading and impact, makes stable drive.
2nd, physical dimension is small：The points of multi point engagement are 3~n points, can at most be determined according to the size position of diameter, this
Sample, has given full play to the effect of passive tooth plate 2, is reduced to monodentate active force original（1/n）/ total number of teeth in engagement Z.Motor work(
Rate is also accordingly reduced, and is conducive to equipment to large-scale development；Small volume is driven, transmission efficiency is more energy efficient.3rd, operational security is reliable：
Because multi point engagement Flexible Transmission is using more than three sets transmission devices, thus wherein a set of damage when, still maintain to operate, can so protect
Continuously running for card equipment, it is critically important during this continuous producing apparatus that can not be stopped to midway.In addition, flexible buffer device subtracts
Lack the dynamic loading to parts and impact, reduce the accident such as off-axis and bolt cutting.Set such as on flexible buffer device
The overload protection measures of various mechanically or electrically devices send signal, main parts size can be protected against damages.4th, manufacture and make
With conveniently：Due to equipment size reduce, weight saving, to manufacture and using bring conveniently.The soft transmission of chain may be designed to the whole series
, during damage can the whole series change.5th, it is hinged simple：Easy for installation to be installed as a result of suspension, most of part is a whole set of
Install, and be not required to positioning centering operation, install very convenient, and capital cost is reduced.
6th, other：Be easily achieved generalization, seriation and standardization, be applicable to rebuilding old equipment improve rotational torque and
It is required that the constant occasion of tactical diameter；Pivoting part is without improving the work bar of revolving structure and other bearings after concentrfated load
Part；To former requiring the design of slewing frame full moment, when being changed to positive negative moment design and still ensuring that safe operation, it can reduce at double
Driving torque is so as to reach energy-conservation purpose.Application：
Multiple spot chain Flexible Transmission has superiority more obvious than common drive.Multiple spot chain engagement flexible gearing is applied to
On the heavy-duty machinery transmission devices such as metallurgical mine environmental protective chemical industry water process, the special work(such as its low-speed heave-load big speed ratio can be realized
Can, progressively development should use chain type Flexible Transmission technology and its device.
The conductive process of driving force：By the rotation of sprocket for main drive 13 chain 8 moment of torsion by driven sprocket 6 with rising
The outside engagement place of chain passes to passive tooth plate 2 between bearing up pulley 3.
The mechanism of Flexible Transmission：First accumulator 4 is by swing arm 10, hinge 5, driven sprocket 6 with expansion tightening wheel 3 chain
Bar 8 is fitted on passive tooth plate 2.
Pole 7 is released certain distance by expansion tightening wheel 3 along the slideway in floating arm 11, loose chain 8 is reached tensioner
Purpose.
The utility model is particularly suitable for turning round the flexible self-adjusting system of class or speed straight line one-way movement class in major diameter
System can keep effective transmission torque under severe conditions；The drive characteristic of this transmission be applied to large-scale heavy duty it is horizontal at a slow speed or
Vertical revolving equipment.Average ratios are accurate, reliable operation, efficiency high；Transmit power big, overload capacity is strong, under identical operating mode
Transmission size it is small；Required tensile force is small, and the pressure acted on axle is small；Can in high temperature, humidity, many dirt, have pollution etc. severe
Worked in environment.Compare general Chain conveyer and increase gearratio, save the length of chain.
This transmission has stable drive, and processing is simple, and overlap coefficient is big, strong adaptability, and centre-to-centre spacing requires low, weares and teares small,
Long lifespan.
Chain conveyer form in the present embodiment is to be delivered to the motion of sprocket for main drive 13 and power by chain 8 to have
A kind of kind of drive of the driven sprocket of special tooth profile.
The present embodiment multiple spot chain type flexible gearing：Multiple spot chain type flexible drive mechanism is realized to some rotating part
The multiple spot of part drives simultaneously, and has very big breakthrough in the scope of gearratio and the scope field of major diameter dimension.
The soft transmission device of multiple chains can be arranged on the same centre of gyration, single-point active force can be reduced to total driving force n
/ mono-；
In F/n formulas：
n:Represent install transmission altogether how many.
F:Represent the summation of driving force.
Multiple spot chain type flexible drive mechanism is also eliminated because pivoting part deviation phenomenon caused by driving force is unbalanced.Can
The soft transmission device of multiple chains is arranged on the same centre of gyration, single-point active force can be reduced to n/mono- of total driving force.
In this transmission, multiple spot chain type flexible drive mechanism is realized to be driven simultaneously to the multiple spot of some pivoting part
It is dynamic, and the scope of gearratio can be very big；The Spatial General 6 R that is also greatly expanded in terms of major diameter can reach that tens arrive
Rice up to a hundred.
The many flexible gearings of chain increase gearratio, major diameter adaptability than general chain drive, improve chain
Utilization rate, save chain, it is less demanding to centre-to-centre spacing.
Such a drive mechanism causes drive apparatus to realize miniaturization, the miniaturization of unit consumption power, transmission mode multiple spot
It is driven simultaneously.Huge and stable driving force is provided to equipment.For mechanized equipment strong support is provided towards maximization development.
