Description
Technical Field
The utility model belongs to the technical field of the motor, especially, relate to a centrifugal fan of vertical synchronous motor and brake disc composite construction.
Background
The vertical synchronous motor is provided with a centrifugal fan and a brake disc, and the centrifugal fan mainly has the following functions: when the vertical synchronous motor operates, the centrifugal fan rotates along with the rotor to drive air in the motor to flow, a flow field is established, and heat generated when the motor operates is taken away. The main functions of the brake disc are as follows: when the vertical synchronous motor is stopped, the time required for stopping the motor is short in order to protect the motor, and the braking force is generated by braking a brake disc mounted on a rotor yoke, so that the stopping time is reduced.
As shown in fig. 1 and 2, a conventional vertical synchronous motor has a centrifugal fan 1 and a brake disk 2 which are two separate parts, and are separately manufactured and separately installed. Particularly, when the radial space inside the vertical synchronous motor is small, the centrifugal fan 1 and the brake disk 2 may interfere with each other spatially, resulting in a failure in installation. And also increases the manufacturing cost and the labor intensity.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a simple structure can solve when the inside radial space of vertical synchronous motor is narrow and small, can produce the vertical synchronous motor centrifugal fan and the brake disc composite construction of radial space mutual interference problem when two independent parts of centrifugal fan and brake disc are installed, and it reduces radial installation space greatly, has reduced manufacturing cost and artifical intensity of labour.
The utility model adopts the technical proposal that: a vertical synchronous motor centrifugal fan and brake disc composite structure comprises a centrifugal fan and a brake disc, wherein the brake disc is fixedly installed at the bottom of the centrifugal fan, and the centrifugal fan and the brake disc are coaxial.
In the above-mentioned vertical synchronous motor centrifugal fan and brake disc composite structure, the centrifugal fan includes a fan bottom ring, a plurality of fan blades and a fan outer ring; the fan bottom ring is arranged parallel to the fan outer ring, the fan bottom ring is coaxial with the fan outer ring, and the plurality of fan blades are welded between the fan bottom ring and the fan outer ring.
In the centrifugal fan and brake disc composite structure of the vertical synchronous motor, the brake disc is annular, the brake disc is positioned in a central hole of an outer ring of the fan, and the brake disc is coaxial with the outer ring of the fan; the top surface of brake disc and the bottom welding of a plurality of fan leaf, the lateral surface of brake disc and the side welding of fan outer loop hole.
In the centrifugal fan and brake disc composite structure of the vertical synchronous motor, the plurality of fan blades are uniformly arranged along the circumferential direction.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model combines the centrifugal fan and the brake disc into an integral structure, has simple structure, is arranged at the bottom of the rotor yoke of the vertical synchronous motor when in use, and can be used as the centrifugal fan when the motor runs and as the brake disc when the motor is stopped; meanwhile, the functions of a centrifugal fan and a brake disc are realized, the size of a radial installation space is greatly reduced, and the manufacturing cost and the labor intensity are also reduced; and the problem of mutual interference of radial spaces generated when two independent parts of the centrifugal fan and the brake disc are installed is effectively prevented.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 3 and 4, the utility model comprises a centrifugal fan 1 and a brake disc 2, wherein the brake disc 2 is fixedly arranged at the bottom of the centrifugal fan. The centrifugal fan comprises a fan bottom ring 11, a plurality of fan blades 12 and a fan outer ring 13; the fan bottom ring 11 is arranged parallel to the fan outer ring 13, the fan bottom ring 11 is coaxial with the fan outer ring 13, and the plurality of fan blades 12 are welded between the fan bottom ring 11 and the fan outer ring 13. The plurality of fan blades 12 are uniformly arranged along the circumferential direction.
The brake disc 2 is annular, the brake disc 2 is positioned in a central hole of the fan outer ring 13, and the brake disc 2 is coaxial with the fan outer ring 13. The top surface of the brake disc 2 is welded with the bottoms of the fan blades 12, and the outer side surface of the brake disc 2 is welded with the side surface of the inner hole of the fan outer ring 13. The utility model discloses compound integrative structure into with 2 with brake discs of centrifugal fan, through 11 fixed mounting in the bottom of vertical synchronous motor's rotor yoke 4 of fan bottom ring. When the motor operates, the utility model relates to a centrifugal fan uses, when the motor shuts down, the utility model relates to a brake disc uses, has realized centrifugal fan and brake disc function simultaneously. The utility model greatly reduces the size of the radial installation space, and also reduces the manufacturing cost and the labor intensity; and the problem of mutual interference of radial spaces generated when two independent parts of the centrifugal fan and the brake disc are installed is effectively prevented.
