Abstract
The utility model relates to a connection mechanism which is used for connecting a cooling fan with a rotating shaft of a dust-collector motor. The connection mechanism comprises the rotating shaft and the cooling fan, wherein one end of the rotating shaft is equipped with a connection portion, the center of the cooling fan is provided with a shaft groove, the connection portion includes a straight-grain knurling structure, the shaft groove includes a through hole structure, and the external diameter of the connection portion is greater than the internal diameter of the shaft groove. The connection mechanism can prevent the cooling fan from flyout under a rotation block condition, thereby ensuring the safety.
Description
Technical field
The utility model relates to a kind of bindiny mechanism, for being connected of motor of dust collector cooling fan and rotating shaft.
Background technology
The mode that the cooling fan of traditional motor of dust collector is threaded connection is fixed in rotating shaft, and the connecting portion of rotating shaft is established external screw thread, and the axial trough of cooling fan is established internal thread, when motor generation gambling turns brake, due to inertia, cooling fan flies out, and has had a strong impact on safety in utilization.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of bindiny mechanism.
Technical solutions of the utility model are as follows:
A bindiny mechanism, comprises rotating shaft and cooling fan, and one end of described rotating shaft is provided with connecting portion, described cooling fan central authorities are provided with axial trough, described connecting portion adopts straight knurling type structure, and described axial trough adopts through-hole structure, and the external diameter of described connecting portion is greater than axial trough internal diameter.
The external diameter of the utility model connecting portion is greater than axial trough internal diameter, is aided with frock and is pressed into axial trough internal diameter during assembling, makes cooling fan realize slight interference with rotating shaft straight knurling and coordinates, even in the situation that gambling turns, cooling fan can not fly out yet, and has guaranteed fail safe.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the front view of cooling fan 3;
Fig. 4 is traditional syndeton schematic diagram;
