Triangular flange opening coupling

Abstract

The invention discloses a triangular flange opening coupler which comprises a fastening diaphragm, half couplings are arranged on the two sides of the fastening diaphragm, triangular flange plates are arranged on the outer walls of the half couplings, and the fastening diaphragm is connected with the two triangular flange plates through fasteners. A half opening is axially formed in the half coupling in a penetrating mode, the position, corresponding to the half opening, of the outer wall of the half coupling is in threaded connection with a loose opening puller bolt and two fastening bolts, and arc notches are evenly formed in the circumferential side of the fastening diaphragm. Through mutual cooperation of the fastening diaphragm, the half-coupling, the triangular flange plate, the fastener and the half-opening, the integral structure is simple and balanced, the outer circle size is small, the performance is stable and reliable, mounting and dismounting are convenient and fast, the state of the coupler is visual and clear during maintenance, the application range is wider after the size is reduced, the integral weight is light, and the production and machining cost is low; the product is high in cost performance and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a triangular flange open shaft coupling. Background technique [0002] All kinds of mechanical transmission shaft torque transmission systems in the machinery manufacturing industry rely on highly elastic metal diaphragm groups to transmit torque, and their mating surfaces are rigidly connected without gaps, running smoothly, with good shock isolation and vibration reduction effects, cushioned start, small impact, and high load-carrying capacity. Large, excellent and reliable product performance, a wide range of applications. [0003] The structure of the traditional diaphragm coupling refers to the accompanying drawings in the manual Figure 1 As shown, its working principle is that the six evenly distributed round holes of the diaphragm group are spaced and fixed on the left and right half-couplings with refined bolts, and the two half-couplings are respectively connect...

Problems solved by technology

[0003] The structure of the traditional diaphragm coupling refers to the accompanying drawings in the manual Figure 1 As shown, its working principle is that the six evenly distributed round holes of the diaphragm group are spaced and fixed on the left and right half-couplings with refined bolts, and the two half-couplings are respectively connected with the left and right half-couplings. After the driving drive shaft and the driven drive shaft at the two ends are tightened and connected by the bolts on the shrink sleeve, the torque transmission between the left and right ends can be completed. Difficult tightening and deformation at the flange end of the coupling leads to a large fit gap with the transmission shaft, and the reliability of tightening and fixing is not high and easy to loosen. At the same time, this type of coupling is inconvenient to install and disassemble, and the production cost is high and the cost performance is low.
