Abstract
The utility model discloses a kind of yielding couplings, including driving shaft, driven shaft, left half a coupler, right half a coupler, the left half a coupler, right half a coupler inner face be provided with protrusion spline, elastic ring and guard ring engaged therewith are set gradually outside the spline of the protrusion, and shaft coupling expansion set is provided on the driving shaft, driven shaft.The utility model has the beneficial effects that: installing taper expansion set between the spline due to devising protrusion and elastic ring engaged transmission and shaft coupling inner hole and axis; convenient for the installation of shaft coupling; it avoids shaft coupling inner hole and axis is that transition fit or interference fit bring install constant disadvantage; and define axial float of the elastomer in shaft coupling operating; improve the running stability of shaft coupling; have the function of buffering, damping and stabilized (steady-state) speed; components can be protected not to be damaged, elongated component service life.
Description
Technical field
The utility model shaft coupling technical field, more particularly, to a kind of yielding coupling.
Background technique
Shaft coupling is to be allowed to rotate jointly to transmit for two axis (driving shaft and driven shaft) coupled in different institutions
The machine components of torque, play linking.So shaft coupling joins two axis due to manufacture to the very high to neutrality requirement of shaft coupling
The many factors such as error, installation, relative motion between component and generate relative displacement.Axis is caused not to be overlapped, in the running
The phenomenon that unbalanced centrifugal inertia force, centrifugation inertia idol power and dynamic deflection (vibration shape) will be generated, this energy imbalance necessarily draws
Rise shafting vibration, axis it is loaded and generate deformation, pedestal deformation, bearing wear, temperature change (expanding with heat and contract with cold) influence machine
The normal work and use service life, currently, generally selecting the flexible coupling having elastic component, there are commonly quincunx shaft couplings
There is the disadvantages of transmitting torque is small, heatproof is low, live replacement vulnerable part is cumbersome, Adjustment precision is high in device, this plum shaft coupling.Replace plum
Flower pad trouble is needed blower and the mobile a distance of motor.This is the deficiencies in the prior art.
Summary of the invention
The purpose of the utility model is to overcome disadvantages existing in the prior art, provide a kind of yielding coupling, not only
The relative displacement between master and slave moving axis can be adjusted, the effect of buffering, damping and stabilized (steady-state) speed is also had both, components can be protected
It is not damaged, elongated component service life.The technical solution adopted is that: a kind of yielding coupling, including driving shaft, driven shaft,
Left half a coupler, right half a coupler, feature are provided with protrusion in the inner face of: the left half a coupler, right half a coupler
Spline sets gradually elastic ring and guard ring engaged therewith outside the spline of the protrusion, sets on the driving shaft, driven shaft
It is equipped with shaft coupling expansion set.
The improvement of the utility model has, and the spline of the protrusion is at least arranged 6, is separately positioned on left half shaft coupling
Device, right half a coupler internal diameter and outer diameter between, and there are distances between its internal diameter and outer diameter respectively.
The improvement of the utility model is in addition, be provided with the consistent slot of spline quantity with the protrusion in the elastic ring
The spline of body, the protrusion is engaged with the groove body, and counterbore is arranged in its center.
The improvement of the utility model in addition, the shaft coupling expansion set is cone, be separately positioned on the left half a coupler,
Between right half a coupler and driven shaft, driving shaft, big end setting passes through bolt and the left half a coupler, right half connection in shaft end
The connection of axis device.
The guard ring uses resilient retainer, and two through-holes are at least arranged on its circumference, pass through fastening screw and the bullet
Property circle be connected.
The utility model has the beneficial effects that: spline and elastic ring engaged transmission and shaft coupling due to devising protrusion
Taper expansion set is installed between device inner hole and axis, convenient for the installation of shaft coupling, avoid shaft coupling inner hole and axis be transition fit or
Interference fit bring installs constant disadvantage, and defines axial float of the elastomer in shaft coupling operating, improves
The running stability of shaft coupling has the function of buffering, damping and stabilized (steady-state) speed, components can be protected not to be damaged, and extends zero
Part service life.
