Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: dust catcher motor bearing mounting structure, including motor shaft 1, the outside upper end of motor shaft 1 is connected with loose bearing 2, and loose bearing 2's inside is reserved has and holds gluey groove 3, and loose bearing 2's central inner wall is reserved has inside trompil 4, and loose bearing 2's left side movable mounting has the connection meson 5.

Further, motor shaft 1 is cylindric optical axis design, is favorable to reducing the manufacturing cost of axle, and the help reduces the running cost of equipment, but also can guarantee with the motor axiality, increases the operation stability, and the outside block of motor shaft 1 is connected with loose bearing 2, is favorable to loose bearing 2's self-installation.

Furthermore, glue containing grooves 3 are preset in the movable bearing 2, the glue containing grooves 3 are designed at equal intervals, glue can be placed conveniently, the connection stabilizing effect of the motor shaft 1 and the movable bearing 2 is achieved, and smooth operation of the motor is promoted.

Further, the inside center of the movable bearing 2 is preset with a circular inside opening 4, the inside opening 4 is in clearance fit with the motor shaft 1, the improvement of the clearance between the inside opening and the motor shaft is facilitated, and the movable bearing is used for smooth adhesion of glue.
