[0003] At present, in the fan assembly process, the common method is to connect the fan with the heat sleeve of the rotating shaft or the combination of the fan, the rotating shaft, and the key. CNC lathes are used to process the inner hole of the fan to meet the tolerance and precision requirements, and the processing efficiency is low; if the thermal sleeve needs to heat the fan to expand it during the assembly process, the process will consume energy and time; it is also prone to industrial accidents such as burns

The invention discloses a quickly assembled and disassembled motor fan structure. The motor fan structure comprises a bottom plate, wherein the middle part of the bottom plate is provided with a mounting hole; the bottom plate is provided with split die cast shaft shoulders which are matched with a motor shaft; the split die cast shaft shoulders and the bottom plate are integrally formed through die casting; the split die cast shaft shoulders are positioned on the hole edge of the mounting hole; a gap is formed between the die cast shaft shoulders; the die cast shaft shoulders are provided with fixing holes; a plurality of fan blades are distributed around the bottom plate; the tops of the fan blades are connected with a connecting plate; the edge of the connecting plate is connected with a plurality of fixing pieces; the number of the fixing pieces is the same as the number of the fan blades and the positions of the fixing pieces correspond to the positions of the fan blades; the top ends of the fan blades are connected with the bottoms of the fixing pieces; the bottom plate is provided with a plurality of adjusting holes. The motor fan structure has the advantages of simple structure, convenience in replacement and maintenance, operation reliability and high part machining accuracy.
Description
technical field [0001] The invention relates to the field of motors, in particular to a fast assembly and disassembly motor fan structure. Background technique [0002] The motor converts electrical energy into mechanical energy or converts mechanical energy into electrical energy during operation. During this process, along with the conversion of energy, part of the energy is converted into heat energy and consumed. The accumulation of heat causes the temperature of the motor to rise continuously, but when it reaches a certain value, it will Damage to insulation or lubrication can lead to motor failure or a significant reduction in life. Usually, a fan is installed in the rotating part of the motor. The fan drives air to blow the heating element during the rotation process. The air and the heating element carry out heat exchange and take away part of the heat, thereby reducing the temperature rise of the heating element or achieving a balance between heat dissipation and he...
