Abstract

The invention relates to an elastic spline vibration isolator, which includes an annular inner ring, wherein vibration isolating rubber is arranged between the annular inner ring and an annular outer ring, a spline groove is arranged in an inner ring surface of the annular inner ring, outer convex teeth and inner convex teeth are respectively arranged on an outer ring surface of the annular inner ring and an inner ring surface of the annular outer ring, and are distributed alternately; a distance is reserved between the outer surface of the annular inner ring and the inner surface of the annular outer ring, and is filled with a continuous vibration isolating rubber layer. The vibration isolating and reducing effects are excellent, and the vibration isolating and reducing functions are even and reliable.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and vibration isolation of a transmission system, in particular to vibration reduction and vibration isolation components in a transmission shaft system. . Background technique [0002] The shafting of the large transmission shaft system mostly adopts the form of a segmented shaft, and the driving shaft and the driven shaft are usually connected by a coupling. However, in some engineering fields, for the convenience of shaft installation, the drive shaft and the driven shaft are connected by splines, and a pair of spline pairs are used to transmit the torque of the drive shaft to the driven shaft. Due to the meshing effect between the spline pairs, the vibration of the shaft system is easy to occur; because the spline pair acts as a rigid connection, the vibration of the shaft system is easily transmitted between the segmented shafts, without the effect of vibration reduction and vibr...
