Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples.
As shown in fig. 1-2, a fan motor connecting flange structure includes a motor upper housing 1 and a motor lower housing 2. The middle of the upper motor shell 1 is provided with a shaft hole for extending the output shaft 3 of the motor, and the upper motor shell 1 and the lower motor shell 2 are respectively provided with a connecting flange 4 integrally at the connecting surface of the upper motor shell and the lower motor shell.
The connecting flange 4 is circular ring shaped, four flange connecting lugs 401 are evenly arranged on the two connecting flanges 4 along the circumferential direction, four motor connecting lugs 402 are evenly arranged on one or the two connecting flanges 4 along the circumferential direction, and in the embodiment, four motor connecting lugs 402 are evenly arranged on the two connecting flanges 4 along the circumferential direction.
The motor engaging lug 402 and the flange engaging lug 401 are arranged at intervals, and bolts for fixedly connecting the upper motor shell 1 and the lower motor shell 2 are arranged at the flange engaging lug 401.
The motor connecting lug 402 is provided with a first motor mounting hole 4021 and a second motor mounting hole 4022. Preferably, the pitch of the first motor mounting holes 4021 of the two oppositely disposed motor coupling ears 402 is D1, the pitch of the second motor mounting holes 4022 of the two oppositely disposed motor coupling ears 402 is D2, D1 is 15mm to 20mm larger than D2, and the first motor mounting holes 4021 have an aperture 1mm larger than the aperture of the second motor mounting holes 4022. In this embodiment, D1=127mm, D2=109mm, the outer diameter of the connecting flange 4 is 140mm, the aperture of the first motor mounting hole 4021 is 6.4mm, and the aperture of the second motor mounting hole 4022 is 5.4 mm.
The connection flange 4 of the upper motor shell 1 and the lower motor shell 2 is provided with a grounding bolt hole 4011 on one flange connection lug 401, and the connection flange 4 of the upper motor shell 1/the lower motor shell 2 is not overlapped with the connection flange 4 of the upper motor shell 2/the upper motor shell 1 at the position where the grounding bolt hole 4011 is arranged. A junction box of the motor leads out a grounding wire which can be connected to a connecting flange 4 of the upper shell 1/the lower shell 2 of the motor through a grounding bolt, so that the motor shell is insulated.
