Transmission shaft connecting shaft sleeve

Abstract

The transmission shaft connecting shaft sleeve comprises a shaft sleeve body, a key groove is formed in the inner wall of the shaft sleeve body, a fracture is formed in the side wall, without the key groove, of the shaft sleeve body, and the fracture is provided with a fastening device used for fastening the fracture. According to the transmission shaft connecting shaft sleeve, the fracture is formed in the side wall of the shaft sleeve body, the shaft sleeve body can be more easily arranged on the periphery of a transmission shaft in a sleeving mode, the fastening device can enhance the force of the shaft sleeve body for tightly holding the transmission shaft, the installation stability is guaranteed, the shaft sleeve does not need to be damaged during disassembly, and the fastening device is disassembled; the problem that the shaft sleeve and the shaft diameter are locked together and cannot be disassembled is solved, damage to parts in the overhauling process is avoided, the labor intensity of workers is reduced, and the safety and the working efficiency of overhauling operation are greatly improved. In addition, the transmission shaft connecting shaft sleeve is small in size, light in weight, simple in structure, convenient to use and maintain, easy to popularize in a large scale and wide in practicability.

Description

technical field [0001] The invention relates to the technical field of long-shaft pumps, and more particularly, to a drive shaft connecting shaft sleeve. Background technique [0002] The long-shaft pump is a deep basin water intake equipment that is widely used by industrial enterprises. Each section of the long-shaft pump is connected by a shaft sleeve. The motor at the top of the pump body drives the impeller at the bottom of the pump barrel to rotate through each section of the drive shaft. So as to realize the pump water work. Because the drive shaft is immersed in water for a long time, when the water source is not clean and corrosive, the drive shaft and the shaft sleeve will be blocked and locked together due to rust and other reasons. Remove it from the top and use the method of destroying the bushing to remove not only the bushing, but also the shaft diameter of the drive shaft. It not only increases the cost of maintenance, but also prolongs the construction per...

AI Technical Summary

Problems solved by technology

Because the transmission shaft has been soaked in water for a long time, when the water source is unclean and corrosive, the transmission shaft and the shaft sleeve will be blocked and locked together due to corrosion and other reasons. It is difficult to remove the shaft sleeve from the transmission shaft during maintenance of the long shaft pump. Remove it from the top, and use the method of destroying the shaft sleeve to disassemble not only damage the shaft sleeve, but also often cause damage to the shaft diameter of the transmission shaft

It not only increases the maintenance cost, but also prolongs the maintenance period
