Thread quick-dismantling device applied to coupling water pump

Abstract

The invention discloses a thread quick-dismantling device applied to a coupling water pump. The thread quick-dismantling device comprises a water pump impeller, a bearing, a water pump shaft and a coupling. The coupling and the water pump shaft are assembled in a threaded mode, and the water pump impeller and the water pump shaft are assembled in a threaded mode. The spiral directions of threads are arranged in the automatic locking directions of working and bearing. The water pump impeller is similar to a nut and tightly presses an impeller flat washer and a copper-lead torsion compound gasket by being connected with the water pump shaft in a threaded mode. The water pump impeller is in threaded rigid connection with one end of the water pump shaft. Clamping hoop parts are arranged at the other end of the water pump shaft in a sleeving mode, the water pump shaft is sleeved with a coupling flat washer, then, the coupling which is similar to the nut is screwed in, and all parts are reasonably locked, so that the clamping hoop parts, the coupling similar to the nut and the other end of the water pump shaft are also connected in a rigid mode. According to the thread quick-dismantling device applied to the coupling water pump, the problems that the threads are continuously and automatically locked and not easy to disassemble during assembling under the loading effect can be effectively solved, and a clamping hoop gasket is provided with elliptical holes so as to enhance the axial elasticity; the thread quick-dismantling device is especially suitable for convenient disassembling of a large-size component after the large-size component is locked in a threaded mode, and the effect is particularly remarkable.

Description

technical field [0001] The invention relates to a threaded quick release device applied to a coupling water pump, which belongs to the field of machinery. Background technique [0002] Pump is a general-purpose mechanical equipment with a large number of fields. It is widely used in various departments of petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding, agriculture and national defense, and occupies an important position in the national economy. With the increasing production scale of chemical industry and mining, large-flow water pumps are often needed to meet the transportation requirements. The structure of ordinary water pumps is generally that one end of the pump shaft is the pump impeller, and the other end is the power input end of the motor, which is often a coupling. . Since water pumps generally run continuously for a long time, the bearings are easily damaged. To replace the bearings, it is generally necessary to disassemble the wat...

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
