A method of assembling and replacing the spring plate of a snake spring coupling

Abstract

The invention discloses a method for assembling and replacing a spring plate of a snake spring coupling, which adopts the mode of clearance fit between an expansion sleeve and a half-coupling, and adopts the form of a flexible link insert piece of a split spring type that can be cut at will, and effectively The product adaptability of the snake spring is improved. When the spring of the coupling is damaged or deformed, the coupling can be opened and replaced as needed. It does not need to be disassembled and replaced as a whole. Only the damaged or deformed spring needs to be replaced, which saves costs and improves work efficiency. efficiency. The invention effectively improves the reliability of the serpentine spring coupling, effectively reduces the time and labor cost of installation and maintenance, and has a simple structure and remarkable effect, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a method for assembling and replacing a spring plate of a snake spring coupling. Background technique [0002] Snake spring coupling is the most advanced shaft connection transmission component in the international machinery field, and is widely used in heavy machinery and general machinery occasions. The existing snake spring coupling has two ways to connect the shaft, one is the key connection, and the other is the expansion sleeve connection. Among them, the spring coupling connected by the expansion sleeve is to install the expansion sleeve inside the half coupling. By tightening the screws, the inner ring and the outer ring of the expansion sleeve are tightened at the same time, and the inner ring and the equipment shaft, the outer ring and the half coupling All achieve interference fit, so as to achieve the effect of transmitting torque. [0003] In the prior art, the expansion sleeve is installed inside the semi-coupli...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the expansion sleeve is installed inside the half coupling. Because the expansion sleeve needs to be composed of multiple parts such as inner ring and outer ring, the installation process is more complicated.

In the later maintenance, the snake spring coupling needs to be fully opened, and the expansion sleeve can be observed by moving the equipment, and the expansion sleeve can be thoroughly maintained. Therefore, this structure makes maintenance more complicated, time-consuming and laborious.

Moreover, during operation, the snake spring coupling is sealed as a whole, and the real-time situation of the internal expansion sleeve cannot be observed

[0004] Moreover, the snake spring of the snake spring coupling in the prior art is composed of 2-5 arc-shaped reeds, which is inconvenient to install and disassemble, and the area involved in damage and replacement is relatively large, which is easy to cause waste, and the snake of this structure The spring processing process is complex and the production cost is high, resulting in high maintenance and replacement costs
