Thread quick detaching device for water pump of belt pulley

Abstract

The invention discloses a thread quick detaching device for a water pump of a belt pulley. The thread quick detaching device for the water pump of the belt pulley comprises a water pump impeller, a bearing, a water pump shaft and the belt pulley, wherein the belt pulley and the water pump shaft are assembled in a threaded manner; the water pump impeller and the water pump 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 water pump impeller which is similar to a nut is in threaded connection with the water pump shaft and tightly presses an impeller flat washer and a copper-plastic reverse bending composite gasket; the water pump impeller is rigidly connected with one end of the water pump shaft in a threaded manner; a clamp part sleeves the other end of the water pump shaft; a belt pulley flat washer sleeves the water pump 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 water pump shaft. By the thread quick detaching device, the problem that threaded assembly is automatically locked continuously and is not easy to detach under the effect of a load can be solved effectively; and the thread quick detaching device is particularly suitable for conveniently detaching large components after threaded locking, and the effect is quite remarkable.

Description

technical field [0001] The invention relates to a threaded quick release device applied to a pulley 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, often a pulley. Because 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 water pump impell...

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
