Thread quick detaching device for fan of belt pulley

Abstract

The invention discloses a thread quick detaching device for a fan of a belt pulley. The thread quick detaching device for the fan of the belt pulley comprises a fan impeller, a bearing, a fan shaft and the belt pulley, wherein the belt pulley and the fan shaft are assembled in a threaded manner; the fan impeller and the fan shaft are assembled in a threaded manner; a thread turning direction is a direction in which automatic locking is implemented along with operation and load bearing; the fan impeller which is similar to a nut is in threaded connection with the fan shaft and tightly presses an impeller flat washer and a copper-plastic reverse bending composite gasket; the fan impeller is rigidly connected with one end of the fan shaft in a threaded manner; a clamp part sleeves the other end of the fan shaft; a belt pulley flat washer sleeves the fan shaft and then the belt pulley which is similar to a nut is screwed in, and all parts are locked reasonably, so that the clamp part and the belt pulley which is similar to the nut are rigidly connected with the other end of the fan shaft. By the thread quick detaching device, the problem that thread assembly is automatically locked continuously and is not easy to detach under the effect of a load can be solved effectively, and an oval hole is formed in a clamp gasket so as to improve axial elasticity; and the thread quick detaching device is particularly suitable for conveniently detaching large components after threaded locking, and the effect is particularly remarkable.

Description

technical field [0001] The invention relates to a threaded quick release device applied to a pulley 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 the fan...

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
