Embodiment Construction
[0015] Describe the present invention below in conjunction with specific embodiment:
[0016] The simple elastic spline sleeve in this embodiment is composed of a metal outer ring 1 , a metal inner ring 3 and an elastic layer 2 . Refer to attached figure 2 And attached image 3 , The metal outer ring and the metal inner ring are coaxially matched, the metal outer ring is connected to the driving part through threads, and the metal inner ring is connected to the driven part through a spline. The overlapping part of the metal outer ring and the metal inner ring is fixedly connected through the elastic layer, and the elastic layer is closely attached to the inner peripheral surface of the metal outer ring and the outer peripheral surface of the metal inner ring. In this embodiment, natural rubber is used for the elastic layer, and the natural rubber elastic layer is vulcanized between the metal outer ring and the metal inner ring through vulcanization treatment. The transmiss...

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 [0001] The invention relates to the technical field of mechanical connection structures, in particular to a simple elastic spline sleeve capable of reducing vibration transmission. Background technique [0002] Most rotating machines are composed of a driving part and a driven part, and the torque is often transmitted between the driving part and the driven part through a spline sleeve. The spline sleeve has the advantages of simple structure, convenient installation, high reliability and wide application range. The commonly used spline sleeve structure is as follows: figure 1 As shown, most of them are directly rigidly connected to the driving part and the driven part, which lacks a good vibration isolation effect. Contents of the invention [0003] technical problem to be solved [0004] In order to solve the shortcomings of the lack of good vibration isolation effect of traditional spline sleeves, the present invention proposes a simple elastic spline...
