Detailed Description

The technical solutions of the present embodiments will be clearly and completely described below with reference to the drawings in the present embodiments, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, based on the embodiments herein, which would be within the purview of one of ordinary skill in the art without the creative effort, are contemplated as falling within the scope of the present invention.

Referring to fig. 1-2, an embodiment of the present invention provides: the utility model provides a prevent structure of not hard up and drunkenness of bearing, including rotor 1, the surface mounting of rotor 1 output has bearing 2, and the surface mounting of bearing 2 has mounting 3, and fixed orifices 31 have all been seted up at the both ends of mounting 3 top both sides, and the cooperation between through fixed orifices 31 and bolt 4 is with mounting 3 stable firm the installing on the electric tool shell, and through-hole 32 has been seted up to the intermediate position at mounting 3 top, fixes bearing 2 on mounting 3 through-hole 32, avoids bearing 2 to appear not hard up and the condition of drunkenness, and bolt 4 is installed through fixed orifices 31 to mounting 3.

In this embodiment, the outer surface of the output end of the rotor 1 is divided into a limiting area and a transmission area, the size of the limiting area on the rotor 1 is matched with the size of the inner ring of the bearing 2, and the output end of the rotor 1 is sleeved with the inner ring of the bearing 2, so that the bearing 2 is limited by the rotor 1 and the fixing piece 3.

In this embodiment, the size of the through hole 32 is adapted to the size of the outer ring of the bearing 2, and the fixing member 3 is sleeved with the outer ring of the bearing 2 through the through hole 32, so that the bearing 2 can be stably and firmly mounted on the fixing member 3 through the through hole 32.

In this embodiment, the size of the fixing hole 31 is adapted to the size of the bolt 4, and the fixing member 3 is connected to the bolt 4 through the fixing hole 31, so that the fixing member 3 can be stably and firmly mounted on the electric tool through the fixing hole 31 and the bolt 4.

In this embodiment, the two sides of the top of the fixing member 3 are provided with connecting holes, so that the transmission structure of the electric tool is fixed through the connecting holes.

The working principle is that the bearing 2 plays a role in limiting the bearing 2 through the matching between the rotor 1 and the through hole 32 on the fixing piece 3, and the condition that the bearing 2 is loosened or moved when the electric tool works is avoided.

It will be evident to those skilled in the art that the present invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention.
