Novel combined type bidirectional flexible diaphragm coupling with tubular long shaft and method for manufacturing novel combined type bidirectional flexible diaphragm coupling with tubular long shaft

Abstract

The invention discloses a novel combined type bidirectional flexible diaphragm coupling with a tubular long shaft. The novel combined type bidirectional flexible diaphragm coupling with the tubular long shaft comprises a first assembly, a second assembly and the tubular middle long shaft (8), wherein the first assembly and the second assembly are connected to the two ends of the tubular middle long shaft (8) in a split type combined middle joint (7) respectively. The novel combined type bidirectional flexible diaphragm coupling with the tubular long shaft has the advantages that metal diaphragm elements are adopted, no tooth space exists, the torsional rigidity is good, the coupling is suitable for high-temperature occasions, the manufacturing accuracy is high, the dynamic balance accuracy is high, the operation speed is high, vibration is small, and the noise is low; compared with other couplings which can transmit the same torque as the novel combined type bidirectional flexible diaphragm coupling, the novel combined type bidirectional flexible diaphragm coupling has the advantages that the structure is compact, the radial size is small, the radial length can reach 2000 mm-2500 mm, the transmitted torque is large, the performance is stable, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of machine tool parts, in particular to a novel combined tubular long-axis bidirectional elastic diaphragm coupling and a preparation method thereof. Background technique [0002] In the two-way elastic diaphragm couplings produced and used in the domestic market, the middle section is a welded integral structure; in order to remove the internal stress generated after welding, the middle section will be deformed during the heat treatment process, and subsequent processing It is difficult and the coaxiality and linearity are difficult to achieve the design accuracy. The manufacturing accuracy is the foundation and key of dynamic balance. The low precision of the intermediate section leads to low dynamic balance accuracy of the coupling, which makes it difficult to meet the dynamic balance requirements of the coupling with low vibration and low noise.
