Description
Technical field:
This patent belongs to gearing field, and in particular to one kind forms elasticity side using U-board spring as elastic element
Frame shape is able to achieve the very high big torque of very large deflection, the elasticity of torsion, transmission capacity, large deflection U-board spring coupling.
Background technique:
At present using metal spring, rubber, plastics etc. as there are many yielding couplings of middle elastic members.Common metal
It is elastic element mechanical strength, rigidity height, large carrying capacity, reliable, but elasticity, damping characteristic are not as good as rubber, plastics.Rubber, modeling
The high molecular materials elastic elements such as material do not need generally to lubricate, and allow to connect the two relatively large offsets of axis axis, but have material old
Change problem, durable safety are poor.Each own respective different feature and limitation.It is only applicable to respectively different driving torques,
The occasion of operating condition.
Summary of the invention:
It is insufficient for existing various yielding coupling reapective features and limitation, the purpose of the present invention is: formulating one kind can
Big torque is transmitted, there is favorable elasticity, vibration damping, large deflection, be not required to lubricate, can be used for high temperature, humidity, more dirt, corrosive environment
High-performance elastic shaft joint.It is able to satisfy modern high power, big torque, big elastic deflection again simultaneously, various different items can be used for
Part, the needs of environment transmission are simple and compact, durable reliable.
The concrete scheme (Fig. 1) (Fig. 2) that the present invention solves its technical problem is: there are two symmetrical cloth for shaft coupling (1) one end
The dog set is in fork-shaped.Assemble the dog of latter two shaft coupling (1).Insertion alternate with each other, similar common embedded clutch.
It is (α) with respect to the angle in gap between every two dog (S).Two shaft couplings (1) are with one heart, outer between every two dog (S)
If it is in 90 ° of dry plate U-shaped spring (2) that enclosing, which has 1 group of both sides angle,.(Fig. 1) is sandwiched between backing plate (5).So 4 groups of plates in periphery
Spring (2) is superimposed, and it is each right to be anchored on the opposite insertion of two shaft couplings (1) respectively with bolt (3), pressing plate (4), backing plate (5)
The periphery of dog.Constitute 4 side square frame-shaped elastic constructions.
The principle of the present invention is: two shaft coupling (1) inner holes are separately connected both ends master, driven shaft with spline (or flat key)
(being not drawn into master and slave moving axis figure).Driving shaft drives the shaft coupling that side is keyed with it, and it is each that drive periphery is bolted
Group U-board spring (2).By the U-board spring of flexible deformation, then other side shaft coupling and its driven shaft is driven to rotate.
It is acted on by the moment of inertia in transmission system and the moment of resistance.Master and slave two shaft couplings, relative resilient reverses δ under loads
Angle (Fig. 1), makes with respect to two groups deformations of square frame-shaped, and flat spring is from being originally that 90 ° of (a) shape extensional deformations are approximately (b) in the arc-shaped.
And relatively another two groups of U-board springs are compressed into the deformation curve (d) of approximate several circular arc compositions then by original 90 ° of (c) shapes
Shape.Around the torque of rotation center, size and the moment of resistance balance its active force.To buffer load change in transmission, vibration damping.This hair
In bright structure, increases the piece number of every group of U-board spring (2), the thickness of thickness and backing plate (4), will more improve its carrying
Ability realizes big torque large deflection elastic transmission.
Existing various yielding couplings are compared, advantages and advantages of the invention are:
1, structure of the invention is reliable, large carrying capacity, high resiliency, large deflection, can pass through the piece of every group of U-board spring of increase and decrease
Number, thickness and plate thickness adjust its torsion stiffness and transmission capacity, manufacture, assembly and disassembly, are not necessarily to mobile shaft coupling and master and slave axis,
It safeguards very convenient.Be not required to lubricate, can be used for various work condition environments, product from the transmission less than 1 kilowatt supreme ten thousand kilowatts or more,
Versatility is good, applied widely, and transmission efficiency is up to 98% or more.
2, the present invention has good vibration absorption energy, and bearing relative torsional angle when nominal torque, up to 15 °, maximum can prevent up to 30 °
Only torsional resonance, buffering variation shock loading, securely and reliably.
3, outer dimension of the present invention is than existing yielding coupling, about small 1/2 to 1/3 under same loaded condition.It is simple and reliable,
Manufacturing cost one reduces 1/3 to 1/4 than corresponding existing yielding coupling, and when installation does not need the higher accuracy of alignment of two axis.
