Description
Technical field
The present invention relates to a kind of elastic connecting device, it is mainly used in machine driven system, belongs to mechanical transmissioning technology neck
Domain.
Background technology
In machine driving, reductor main function is by prime mover (motor, steam turbine, hydraulic motor etc.) output
Moment of torsion and rotating speed are converted into being adapted to the moment of torsion and rotating speed of working machine requirement, but in actual applications, reductor is often born again
Extra radial and axial load.For example when reductor is connected by belt with working machine, the output shaft of reductor will be held
The radial load caused by belt tension.Also when producing axial float in working machine work, reductor will also be produced
Extra axial load.These extra radial and axial load can have undesirable effect to the bearing and gear of reductor, make
Its life-span shortens dramatically.
The content of the invention
It is an object of the invention to provide a kind of attachment means, the device, can be with while reductor and working machine is connected
The axially and radially load that working machine is produced is shielded, reductor is in more reasonably use state.
To reach above-mentioned purpose, the technical scheme is that a kind of elastic connecting device is provided, including cylindrical roller axle
Hold, adapter sleeve, expansion set, spring leaf, outer press ring, inner pressure ring and connecting bolt, spring leaf processed using high-strength spring steel plate and
Into the output shaft of reductor is connected by the upper disk of elastic connecting device and working machine.
Reductor is fixed on matrix, and cylinder roller bearing is arranged in the bearing block of matrix, and the upper disk of working machine is installed
In the endoporus of cylinder roller bearing, it is radially oriented.Left between the endoporus of the output shaft of reductor and upper disk between 1mm
Gap, the radial vibration of working machine is delivered on matrix by cylinder roller bearing, without being delivered on the output shaft of reductor.
Expansion set connects the output shaft of adapter sleeve and reductor, leave 3 between the upper disk of the bottom surface and working machine of expansion set and adapter sleeve~
5mm gaps.One end of spring leaf is fixed on adapter sleeve by inner pressure ring and connecting bolt, and the other end passes through outer press ring and connection
It is bolted on the upper disk of working machine.When working machine produces axial float, spring leaf plays a part of buffering, fully absorbs
Axial float, so that the axial load that the output shaft for substantially reducing reductor is born.
The use of the present invention overcomes the deficiency in existing machinery transmission system in attachment means, can effectively reduce because negative
The axially and radially load that play is produced to reductor is carried, the service life of reductor is significantly extended.

Embodiment
To become apparent the present invention, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below：
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 8, when machine driven system uses elastic connecting device 10, first reductor 13 is consolidated
Fixed cylinder roller bearing 7 is arranged in the bearing block of matrix 12 over substrate 12, and the upper disk of working machine 11 is arranged on cylindrical roller
In the endoporus of bearing 7, it is radially oriented；Left between the output shaft of reductor 13 and the upper disk endoporus of working machine 11 between 1mm
Gap, the radial vibration of working machine 11 is delivered on matrix 12 by cylinder roller bearing 7, without being delivered to the defeated of reductor 13
On shaft；Adapter sleeve 5 is connected by expansion set 6 with the output shaft of reductor 13, bottom surface and the working machine 11 of expansion set 6 and adapter sleeve 5
3~5mm gaps are left between upper disk；One end of spring leaf 3 is fixed on adapter sleeve 5 by inner pressure ring 4 and connecting bolt 2, separately
One end is fixed on the upper disk of working machine 11 by outer press ring 1 and connecting bolt 2, and a number of spring leaf 3 is in circumference uniform distribution
Arrangement, and spring leaf center line 8 and adapter sleeve center line 9 are tangent, being superimposed as spring plate group usually using 3~5 layers of spring leaf 3 makes
With every layer of spring leaf 3 is pressed within ring 4 and outer press ring 1 is separated, and is not directly contacted with；When working machine 11 produces axial float, bullet
Reed 3 plays a part of buffering, fully absorbs axial float, so that the axle that the output shaft for substantially reducing reductor 13 is born
To load.
