Thread fast-dismounting device applied to coupler fan

Abstract

The invention discloses a thread fast-dismounting device applied to a coupler fan. The thread fast-dismounting device comprises a fan impeller, a bearing, a fan shaft and a coupler. The coupler and the fan shaft are assembled through a thread, and the fan impeller and the fan shaft are assembled through a thread; and the thread turning direction is the direction of automatic locking along with work and bearing. The fan impeller is similar to a nut, is in threaded connection with the fan shaft and enables an impeller flat washer and a copper lead reverse-folding composite pad to be pressed, and the fan impeller is in threaded rigid connection with one end of the fan shaft; a clamping part is sleeved with the other end of the fan shaft, and then the coupler flat washer is sleeved with the fan shaft and then is screwed into the coupler similar to a nut; and total locking is carried out reasonably, and the clamping part and the coupler similar to the nut are in rigid connection with the other end of the fan shaft. According to the device, the problem that under the load effect, a thread assembly is continuously and automatically locked and is not prone to being disassembled can be effectively solved, the device is particularly suitable for convenient and rapid disassembling of a large component obtained after thread locking, and the effect is particularly obvious.

Description

technical field [0001] The invention relates to a threaded quick release device applied to a shaft coupling fan, belonging to the field of machinery. Background technique [0002] The fan is a very widely used machine. It can be seen in most of the occasions that require ventilation. With incomplete statistics, the fan has been widely used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships, etc. Hundreds of national economic fields. In addition to traditional application fields, it also has great development prospects in more than 20 potential fields such as comprehensive utilization of coal gangue, technical transformation of new dry process clinker, energy saving in metallurgical industry, and comprehensive utilization of resources. [0003] With the increasing production scale of chemical industry and mining, large-flow fans are often needed to meet the transportation requirements. The structure of ordinary fans is generally that one end of...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
