High-rotating-speed small-torque star-shaped vibration isolation coupler

Abstract

The invention relates to a coupler for high-rotating-speed precision rotating machinery, in particular to a high-rotating-speed small-torque star-shaped vibration isolation coupler, which comprises adriving shaft end connector and a driven shaft end connector, and is technically characterized in that the driving shaft end connector consists of a flange plate I and a squirrel-cage-shaped shaft body connected with the flange plate I; a driven shaft end connector is composed of a flange plate II and a star-shaped shaft body connected with the flange plate II; the star-shaped shaft body is inserted into the squirrel-cage-shaped shaft body; at least one set of tension lines with ductility is connected between the star-shaped shaft body and the squirrel-cage-shaped shaft body; and each set of tension lines is composed of a plurality of tension lines symmetrically distributed in the circumferential direction of the star-shaped shaft body. The high-rotating-speed small-torque star-shaped vibration isolation coupler is compact in structure and reliable in use, solves the problem of poor vibration isolation or vibration reduction effect when an existing coupler is applied to a high-rotating-speed precision rotating machine, is beneficial to effectively reducing the influence of shaft end flutter of a driving shaft system on a driven shaft system, and is low in operation noise.

Description

technical field [0001] The invention relates to a shaft coupling for high-speed precision rotating machinery, in particular to a star-shaped vibration-isolation coupling with high speed and small torque. Background technique [0002] In the test research and long-term operation of high-speed precision rotating machinery, such as: aero-engine component test, high-speed slip ring lead-in operation, etc., the gap between the rotating and static parts and the vibration of the shafting have an impact on performance indicators and strength life The impact is huge, and the superimposed effect of the inherent clearance of each fulcrum bearing of the drive shaft and the misalignment between the shafts often leads to obvious chatter at the end of the drive shaft at a high speed of 10,000 revolutions per minute. Isolating or reducing the flutter at the shaft end of high-speed drive shafting has great practical significance for the performance and life of high-speed precision rotating m...
