By using above-mentioned technical proposal, it is connected between shaft and fan by flat key, can be synchronized when shaft rotates Fan is driven to be rotated；In addition it is more laborsaving during fan in dismounting.

Preferably, the diameter that the shaft is located at fan linkage section is less than the diameter that shaft is located at main shaft section, the master The confined planes that axial displacement occurs to main shaft section side for restricted fan are formed between shaft part and fan linkage section.

By using above-mentioned technical proposal, the design of main shaft section is less than by fan linkage section diameter, when installing fan, Fan is socketed in along side of the fan linkage section far from main shaft section outside shaft, and installation is completed in the face of being limited after resisting；It is tearing open When being cleaned except fan, it is only necessary to directly can tear fan open along side mobile fan of the fan linkage section far from main shaft section It removes, disassembly process is simple, is cleaned after conveniently being removed to fan.

Preferably, the shaft is further included positioned at thread segment of the fan linkage section far from main shaft section side, the screw thread Section is threadedly coupled the fan cap that axial displacement occurs to thread segment side for restricted fan.

By using above-mentioned technical proposal, it is threadedly attached in the design of the fan cap of thread segment, fan cap and limiting Fan is carried out axial limiting by face cooperation, is avoided during the use of threephase asynchronous machine, and fan occurs on axial direction Jump.

Preferably, the minimum diameter that the shaft is located at fan linkage section is located at the maximum of thread segment directly not less than shaft Diameter.

By using above-mentioned technical proposal, thread segment is set greater than by the diameter that shaft is located to fan linkage section Maximum gauge can facilitate fan to be socketed on fan linkage section to one side slip of fan linkage section directed along thread segment.

Preferably, the casing includes the radiation shell for being provided with radiating fin and the connection shell for link slot setting.

By using above-mentioned technical proposal, the radiation shell of radiating fin is carried and for link slot by the way that casing is set as The connection shell opened up, radiation shell increase the contact area of casing and outside air, enhance heat transfer between casing and air Effect；Even housing surface is more smooth, and fan housing can be more easily along the outer wall of connection shell into line slip.

In conclusion the utility model has the advantages that：

1. it is whole in the slipping block of strip and four corners through arc transition by the setting of fan housing inner wall, and set on casing The limiting slot that connection is turned to for the slippage slot of slipping block sliding and with slippage slot is put, slipping block slides out of slippage slot, arrives at The groove bottom rear steering of slippage slot enters limiting slot, realizes the connection of fan housing and casing, when removing fan housing by slipping block from It is slid onto in slippage slot in limiting slot, the dismounting of fan housing and casing can be realized by then leaving slippage slot from sliding；

2. the design of main shaft section, fan linkage section and thread segment, the fan cap and fan linkage section that are connected on thread segment The confined planes formed between main shaft section can carry out axial limiting to the fan connected on fan linkage section, avoid fan Axial direction jumps.
