Detailed Description

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

Referring to fig. 3, a low power silicone oil fan assembly includes a clutch 1 and a fan body 2 mounted on the clutch 1.

Referring to fig. 4 and 5, the clutch 1 is composed of a driving shaft 11, a flange plate 12, a clutch transmission 13, a fan connection plate 14 and an end cover 15, wherein the flange plate 12 is fixed at one end of the driving shaft 11, the clutch transmission 13 is installed at the other end of the driving shaft 11, the fan connection plate 14 is installed on the clutch transmission 13, mounting holes 162 aligned with the periphery of the fan connection plate 14 and the end cover 15 are arranged on the periphery of the end cover 15, the end cover 15 is fixed with the fan connection plate 14 through arranging first bolts 17 on the mounting holes 162, the end cover 15 and the fan connection plate 14 form a shell cavity of the clutch transmission 13, and the shell cavity covers the end part of the clutch transmission 13. In addition, referring to fig. 6, the outer circumference of the fan connection pad 14 is provided with a plurality of connection lugs 16 protruding outward at intervals.

Referring to fig. 7 and 8, the fan body 2 is configured by a hub 21 and a plurality of blades 22 fixed to the outer periphery of the hub 21, a fitting hole 211 is provided in the center of the hub 21, and a fitting groove 212 is provided on the end surface of the hub 21. When the fan body 2 is mounted on the clutch 1, the clutch 1 is accommodated in the embedding hole 211, the connecting lug 16 of the fan connecting disc 14 is embedded in the embedding groove 212, the connecting lug 16 is provided with the threaded hole 161, the embedding groove 212 is provided with the connecting hole 213 aligned with the threaded hole 161 of the connecting lug 16, and the second bolt 23 passes through the connecting hole 213 to be connected with the threaded hole 161, so that the fan body 2 is fixed on the clutch 1. The caulking groove 212 is used for facilitating concentric positioning of the fan body 2 and the clutch 1, and improving assembly efficiency and product yield.

Unlike the conventional fan assembly of fig. 1, in which the fan mounting surface on the back of the clutch is located inside the closed coil formed by the connection line of the adjacent mounting holes, the fan assembly is heavy and the center of mass distance is large, while referring to fig. 6, the fan mounting surface originally arranged on the back of the clutch is changed to the periphery of the fan connecting disc 14 of the clutch 1, so that the closed coil formed by the connection line of the threaded holes 161 on the adjacent connecting lugs 16 is located outside the closed coil formed by the connection line of the adjacent mounting holes 162. After modification, the overall thickness of the clutch 1 can be reduced, so that the quality of the clutch 1 is reduced, the overlapping area of the axial projection of the clutch 1 and the axial projection of the fan body 2 accounts for 3% -20% of the axial projection area of the clutch 1, and the overlapping area is a fan mounting surface.

In addition, the fan assembly has better operation reliability, the distance between the plane of the front end of the connecting lug 16 and the plane of the front end of the clutch 1 (i.e. the distance between the plane of the opposite side of the connecting lug 16 connected with the hub 21 of fig. 3 and the plane of the front end of the clutch 1) is 20 mm-70 mm, compared with the traditional clutch, the mounting position of the clutch 1 and the fan body 2 is moved to the middle part of the clutch 1 after being used as a mounting surface, so that the distance from the center of mass of the fan body 2 to the flange plate 12 of the clutch 1 can be reduced, compared with the distance from the center of mass of the fan and the clutch of the same type in the prior art, the operation dynamic balance of the fan assembly is improved, the operation reliability of the fan assembly is improved, and the power consumption of the fan assembly is further reduced.

In addition, the ratio of the diameter of the clutch 1 to the inner diameter of the embedded hole 211 is 1:1.05-1.25, so that a gap is formed between the outer peripheral edge of the clutch 1 and the embedded hole 211, the gap facilitates the passage of middle air flow, and the clutch 1 and the fan body 2 can move in the same direction better under the disturbance of peripheral air flow.

As the preferred scheme, the same caulking grooves 212 are formed in the end faces of the two sides of the hub 21, and the caulking grooves 212 on the two sides are corresponding in position, so that the fan body 2 can be installed on the back of the clutch 1 or on the front of the clutch 1, and accordingly adjustment can be performed according to specific conditions, and the installation suitability of the fan assembly is improved.

The foregoing has outlined rather broadly the more detailed description of the utility model in order that the detailed description of the utility model that follows may be better understood, and in order that the present principles and embodiments may be better understood; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present utility model, the present description should not be construed as limiting the present utility model in view of the above.
