Elastic coupling of one-way precise diaphragm

Abstract

The invention provides an elastic coupling of a one-way precise diaphragm, which has the advantages of simple structure, low cost and capability of supporting large repeated fluctuating loads, impact loads and bending moment. An input flange and an output flange of the elastic coupling and the diaphragm between the input flange and the output flange are connected by bolts; an expansion sleeve consisting of an outer conical ring and an inner conical ring is arranged in shaft holes of an input shaft and an output shaft; the inner conical ring and the outer conical ring are cones which have radial notches and are unclosed in a circumferential direction; the outer peripheral surface of the inner conical ring and the inner peripheral surface of the outer conical ring are conical surfaces which are matched mutually; the elastic coupling also comprises two end covers which are respectively connected with the input shaft and the output shaft through the bolts in an axial direction; and compaction parts which extend into the shaft hole of the input shaft or the output shaft and are contacted with the end face of the expansion sleeve are arranged on the end cover, and when moving along the axial direction, the compaction parts push the inner conical ring or the outer conical ring to move axially and reduce the inner peripheral diameter of the inner conical ring.

Description

technical field [0001] The invention relates to a one-way precision diaphragm elastic coupling. Background technique [0002] One-way precision diaphragm elastic coupling, including an input shaft with a flange at one end, an output shaft with a flange at one end, a diaphragm, and a diaphragm between the flange of the input shaft and the flange of the output shaft The input shaft flange and the output shaft flange and the diaphragm between them are connected by bolts. The input shaft and the output shaft are generally hollow shafts, and key grooves are formed on the walls of the inner holes. When in use, the input shaft is connected to the driving shaft through a key, and the output shaft is connected to the driven shaft through a key, so that the torque of the driving shaft is transmitted to the driven shaft. [0003] However, the structure of the key connection has less ability to withstand alternating loads and impact loads, and the input shaft and driving shaft (output...

Problems solved by technology

[0003] However, the structure of the key connection has a small ability to withstand alternating loads and impact loads, and the bending moment that the input shaft and the driving shaft (output shaft and driven shaft) can withstand is also small.
