Abstract
The invention provides a simple elastic spline housing capable of reducing vibration transfer. The spline housing is composed of a metal outer ring, a metal inner ring and an elastic layer. The overlapped portions of the metal outer ring and the metal inner ring are fixedly connected with the elastic layer, radial bosses are evenly arranged along the circumferential direction on the overlapped portion on the inner circumferential surface of the metal outer ring, radial bosses are evenly arranged along the circumferential direction on the overlapped portion on the outer circumferential surface of the metal inner ring, and the bosses of the metal outer ring and the bosses of the metal inner ring are distributed at intervals. The metal outer ring and the metal inner ring are fixedly connected through the elastic layer which is used for reducing transfer of vibration of driving parts to driven parts. Further, the bosses are arranged on the overlapped portions of the metal outer ring and the metal inner ring, so that torsion strength of the simple elastic spline housing is increased, and torsion between the driving parts and the driven parts is effectively transferred.
Description
Technical field
The present invention relates to the mechanical connecting structure technical field, be specially a kind of Simple elastic spline housing that can reduce to vibrate transmission.
Background technique
Most of rotating machineries are comprised of driver part and driven parts, often come transmitting torque by spline housing between driver part and the driven parts.Spline housing is simple in structure, easy for installation, reliability is high, applied range.The spline housing structure of generally using at present as shown in Figure 1, be mostly directly to be rigidly connected driver part and driven parts lack good vibration isolating effect.
Summary of the invention
The technical problem that solves
Lack the shortcoming of good vibration isolating effect for solving the conventional spline cover, the present invention proposes a kind of Simple elastic spline housing that can reduce to vibrate transmission, reduce to vibrate transmission from from driver part to driven parts by in spline housing, increasing elasitic layer.
Technological scheme
Technological scheme of the present invention is:
Described a kind of Simple elastic spline housing that can reduce to vibrate transmission is characterized in that: be comprised of metal outer ring, metal inner ring and elasitic layer; Metal outer ring and metal inner ring coaxial cooperation, the metal outer ring is fixedly connected with by elasitic layer with the lap of metal inner ring, and elasitic layer and metal outer ring inner peripheral surface and metal inner ring outer peripheral surface fit tightly; And metal outer ring inner circumferential surface evenly is provided with radially boss in the circumferential direction of the circle at lap, and metal inner ring external peripheral surface also evenly is provided with radially boss in the circumferential direction of the circle at lap, and metal outer ring boss and metal inner ring boss are spaced apart.
Described a kind of Simple elastic spline housing that can reduce to vibrate transmission is characterized in that: elasitic layer adopts natural rubber, and elasitic layer vulcanizes between metal outer ring and metal inner ring.
Beneficial effect
The present invention adopts elasitic layer to be fixedly connected with between metal outer ring and metal inner ring, reduces the vibration of driver part to the transmission of driven parts by elasitic layer.And the lap at metal outer ring and metal inner ring arranges boss, increases the torsional strength of Simple elastic spline housing, the moment of torsion between effective communication driver part and the driven parts.

Fig. 3: the sectional view of the spline housing that the present invention proposes;
Wherein: 1, metal outer ring, 2, elasitic layer, 3, the metal inner ring.
Embodiment
Below in conjunction with specific embodiment the present invention is described:
Simple elastic spline housing in the present embodiment is comprised of metal outer ring 1, metal inner ring 3 and elasitic layer 2.With reference to accompanying drawing 2 and accompanying drawing 3, metal outer ring and metal inner ring coaxial cooperation, the metal outer ring is connected with driver part by screw thread, and metal inner ring and driven parts pass through spline joint.The metal outer ring is fixedly connected with by elasitic layer with the lap of metal inner ring, and elasitic layer and metal outer ring inner peripheral surface and metal inner ring outer peripheral surface fit tightly.In the present embodiment, elasitic layer adopts natural rubber, by vulcanizing treatment, the natural rubber elasitic layer is vulcanized between metal outer ring and metal inner ring.Elasitic layer by the centre reduces the vibration of driver part to the transmission of driven parts.
In addition, in the present embodiment, for the moment of torsion between effective communication driver part and the driven parts, increase the torsional strength of Simple elastic spline housing, lap to metal outer ring and metal inner ring is processed, as shown in Figure 3, metal outer ring inner circumferential surface evenly is provided with radially boss in the circumferential direction of the circle at lap, metal inner ring external peripheral surface also evenly is provided with radially boss in the circumferential direction of the circle at lap, metal outer ring boss and metal inner ring boss are spaced apart, corresponding elasitic layer is corresponding concaveconvex structure also, thereby has increased the torsional strength of Simple elastic spline housing, the moment of torsion between effective communication driver part and the driven parts.
Claims (2)
1. the Simple elastic spline housing that can reduce to vibrate transmission is characterized in that: be comprised of metal outer ring, metal inner ring and elasitic layer; Metal outer ring and metal inner ring coaxial cooperation, the metal outer ring is fixedly connected with by elasitic layer with the lap of metal inner ring, and elasitic layer and metal outer ring inner peripheral surface and metal inner ring outer peripheral surface fit tightly; And metal outer ring inner circumferential surface evenly is provided with radially boss in the circumferential direction of the circle at lap, and metal inner ring external peripheral surface also evenly is provided with radially boss in the circumferential direction of the circle at lap, and metal outer ring boss and metal inner ring boss are spaced apart.
