Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
Please refer to Fig. 1: a kind of top drive air cooling means of dynamo, it is air-cooled for being carried out to top-drive motor 3；With traditional technology phase
Same technical characteristic has: the ventilated machine 1 acted including impeller 7, driving impeller 7；
Have with the technical characteristic of traditional technology difference:
The ventilated machine 1 is located at the top of brake disc cover 2 using horizontal mounting means；It can reduce whole height in this way
Degree；
The brake disc cover 2 is located at the top of top-drive motor 3；
The impeller 7 is located at the air inlet of top-drive motor 3；The ventilation cross-sectional area of air inlet is greater than the ventilation of air outlet
Cross-sectional area；
The bearing of the motor shaft and impeller 7 of the ventilated machine 1 is parallel to each other；The ventilated machine 1 is driven by belt
Component is connect with impeller 7.
The working principle of this preferred embodiment are as follows: the rotation of the rotation of the rotation impeller 7 of ventilated machine 1, impeller 7 produces
Raw air-flow enters top-drive motor 3 by the air inlet of top-drive motor 3, is realized at any time to the air-cooled of top-drive motor 3.Total
Succinctly, transmission step is few, energy saving loss.
Preferably, the belt drive component structure in above preferred embodiment is, the belt drive component includes peace
Bearing 8, connection upper belt pulley 4 and the bearing 8 acted loaded on the upper belt pulley 4 on 1 motor shaft of ventilated machine, impeller 7
Belt 6.
