Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In this application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-2, the present invention provides a scraper conveyor power section, which comprises a motor 10, a reducer 20, a coupling 30, a coupling cylinder 40 and a brake 50.

One end of the coupling 30 is connected to an output shaft of the motor 10, and the other end is connected to an input shaft of the reducer 20. The connecting cylinder 40 is hollow and is sleeved outside the coupling 30. A bearing is arranged between the coupling cylinder 40 and the coupling 30, the outer ring of the bearing is fixedly connected with the inner wall of the coupling cylinder 40, and the inner ring of the bearing is fixedly connected with the outer wall of the coupling 30, so that the coupling 30 and the coupling cylinder 40 can rotate.

One end of the coupling cylinder 40 is fixedly connected to a flange 60 of the motor 10, and the other end is fixedly connected to a flange 60 of the reduction gear 20. The coupling cylinder 40 has a through hole 41 formed on an outer circumferential surface thereof to communicate with an inside thereof, the brake 50 is provided outside the coupling cylinder 40, and an operating member 51 of the brake 50 can pass through the through hole 41 to act on an output shaft of the motor 10 or an input shaft of the reducer 20.

The coupling cylinder 40 can reduce the relative displacement between the motor 10 and the decelerator 20 caused by the vibration, thereby improving the coaxiality of the output shaft of the motor 10 and the input shaft of the decelerator 20, so that the shafts of the motor 10 and the decelerator 20 are not easily broken. In addition, since the inner wall of the coupling cylinder 40 is rotatably connected with the inner wall of the coupler 30 through a bearing, the coupling cylinder 40 may also generate a certain force to the coupler 30, so that the shaft of the motor 10 and the shaft of the reducer 20 are further not easily broken.

The working component 51 of the brake 50 can pass through the through hole 41 on the coupling cylinder 40 and act on the output shaft of the motor 10 or the input shaft of the speed reducer 20, so that the operation of the scraper conveyor can be timely braked and accurately controlled.

In one embodiment, the motor 10 is a flameproof motor 10. The housing of the explosion-proof motor 10 can bear the explosion pressure generated when the explosive gas mixture in the housing is detonated, and can prevent the explosive product from penetrating through the explosion-proof gap to ignite the explosive mixture around the motor housing. This is particularly important for the coal industry.

In one embodiment, the coupling 30 is a resilient torx coupling 30. The quincunx coupling 30 is only subjected to extrusion force in the process of transmitting torque, and is not subjected to the torque normally borne by a rotating piece, so that the quincunx coupling is not easy to wear in the using process, and the service life is greatly prolonged.

In one embodiment, the coupling 30 is fixedly connected to the flange 60 of the motor 10 or the reducer 20 by screws 80, and the spring washers 70 are mounted on the screws 80. The spring washer 70 can generate pre-tightening force and prevent the screw 80 from loosening.
