Description

Technical Field

[0001] The utility model relates to the technical field of mine aggregate processing, in particular to a quick disassembly jig for a drive shaft connector of an 800KW motor. Background Art

[0002] A high-voltage motor is one with a rated voltage of 1000V or more. Commonly used voltages are 6000V and 10000V. Due to differences in foreign power grids, voltage levels of 3300V and 6600V are also available. High-voltage motors are produced because motor power is proportional to the product of voltage and current. Therefore, when the power of a low-voltage motor increases to a certain level (such as 300kW / 380V), the current is limited by the allowable carrying capacity of the wires, making it difficult to increase, or the cost is too high. High power output needs to be achieved by increasing the voltage. The advantages of high-voltage motors are high power and strong impact resistance; the disadvantages are high inertia, making starting and braking difficult.

[0003] Currently, when inspecting and replacing the drive shaft connectors of 630KW, 710KW, and 800KW high-voltage motors commonly used in engineering projects, using pullers or other tools to disassemble the connectors is time-consuming, labor-intensive, and difficult, easily damaging the drive shaft or connector. Therefore, this utility model proposes a quick-disassembly jig for the drive shaft connector of an 800KW motor. Utility Model Content
