Description

Technical Field

[0001] The utility model relates to the technical field of electric rollers, in particular to an electric roller convenient for assembly. Background Art

[0002] An electric roller is a new type of driving device that combines a motor and a reducer inside the roller body. It is mainly used in fixed and mobile belt conveyors to replace the traditional separate driving device with a motor and a reducer outside the driving roller. The electric roller has many advantages such as a compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable work, good sealing, small occupied space, and convenient installation. It is suitable for working under various harsh environmental conditions. The existing structure for fixing the motor of the electric roller is to push a steel pipe through other equipment. The pushing force and position are not easy to control, which affects the fixing position of the motor and may cause problems such as noise. The installation of gears, sprockets, cams or multi-wedge belt pulleys is inserted into the steel pipe, and the head needs to be connected by laser welding or screwing and gluing. Screwing is cumbersome, and gluing is likely to fall off at high temperatures or in harsh environments. Laser welding requires a laser machine, which is costly; the assembly between components is rather cumbersome and inconvenient, thus affecting the work efficiency. Content of the Utility Model

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Embodiment:

[0024] Please refer to Figures 1-7 , the present utility model provides a technical solution:

[0025] An electric roller convenient for assembly, including a steel pipe main body 1, one end of the inner wall of the steel pipe main body 1 is slidably connected with a motor 2, one end of the motor 2 is provided with a reduction box 3, the output shaft of the motor 2 extends to the outside of the steel pipe main body 1, and a flange 5 is installed on one side of the inner wall of the steel pipe main body 1 where the reduction box 3 is located. When the electric roller is in use, by rotating between the nut 6 and the screw 4, the first rubber ring 7 can be expanded or contracted, thereby changing the installation position of the motor 2 inside the steel pipe main body 1. After the spring steel sheet ring 11 is inserted into the inside of the steel pipe main body 1 and expanded, the clamping and fixing of the required gear, sprocket, cam or multi-wedge belt wheel can be realized. The structure is simple, the operation is convenient, the assembly between components is fast and convenient, and the work efficiency is improved.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a screw 4 is installed on one side of the flange 5, and the other end of the screw 4 is threadedly connected with a nut 6. The nut 6 and the screw 4 can be selected as plastic parts or aluminum parts. First, the motor 2 is aligned and inserted into the port of the steel pipe main body 1. When moving inside the steel pipe main body 1, the nut 6 is away from the first rubber ring 7 sleeved outside the screw 4. The nut 6 and the screw 4 can be selected as plastic parts or aluminum parts according to the actual working environment and requirements.

[0027] In this embodiment, as Figure 1 , Figure 4 and Figure 5As shown, a first rubber ring 7 is sleeved on the outer wall of the screw rod 4 between the nut 6 and the flange 5. Then, after determining the installation position of the motor 2, twist the nut 6 to make it move on the screw rod 4 and gradually approach the outer wall of the first rubber ring 7 and squeeze it. After the first rubber ring 7 is squeezed, the edge expands accordingly. After expansion, the first rubber ring 7 abuts against the inner wall of the steel pipe main body 1, and then the motor 2 is fixed on the inner wall of the steel pipe main body 1.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 6 shown, an installation groove is provided on the side of the flange 5 close to the speed reducer 3. A second rubber ring 8 is engaged with the inner wall of the installation groove. A gear disk 9 is engaged and connected to the inner wall of the second rubber ring 8 on the inner side of the installation groove. A gear shaft 10 is installed on the side of the speed reducer 3 close to the flange 5. The gear shaft 10 is in sliding connection with the gear disk 9. The flange 5, the first rubber ring 7, and the second rubber ring 8 are all made of polyurethane material. Further, the gear shaft 10 on the speed reducer 3 is inserted into the inner side of the gear disk 9 installed on the flange 5, so that the flange 5 installed at one end of the screw rod 4 is connected to the speed reducer 3 to apply force to the motor 2 and is connected to the speed reducer of the motor 2.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 7 shown, a docking column 12 is slidably connected to the other end inside the steel pipe main body 1. Two sets of annular grooves are provided on the outer side of the docking column 12. Spring steel ring 11 is sleeved on the outer wall of the docking column 12 at both sets of annular grooves. The other end of the docking column 12 away from the motor 2 can be installed with gears, sprockets, cams or multi-wedge belt pulleys. Further, two layers of spring steel ring 11 are sleeved at the annular grooves on the outside of the docking column 12. After the spring steel ring 11 is pushed into the port of the steel pipe main body 1 and expands on the inner wall of the steel pipe main body 1, the effect of fixing the docking column 12 is achieved. The other end of the docking column 12 can be selected to install gears, sprockets, cams or multi-wedge belt pulleys according to actual conditions for use in subsequent work, and the installation is convenient.

[0030] The implementation principle of an electric roller that is convenient for assembly in an embodiment of the present application is as follows: Align the motor 2 and insert it into the port of the steel pipe body 1. When the motor 2 moves inside the steel pipe body 1, the nut 6 moves away from the first rubber ring 7 sleeved on the outer side of the screw 4. The nut 6 and the screw 4 can be made of plastic or aluminum according to the actual working environment and requirements. After determining the installation position of the motor 2, twist the nut 6 to make it move on the screw 4 and gradually approach the outer wall of the first rubber ring 7 and squeeze it. After the first rubber ring 7 is squeezed, the edge expands accordingly. After expanding, the first rubber ring 7 abuts against the inner wall of the steel pipe body 1, thereby fixing the motor 2 on the inner wall of the steel pipe body 1. The gear shaft 10 on the speed reducer 3 is inserted into the inner side of the gear disk 9 installed on the flange 5, and the flange 5 installed at one end of the screw 4 is connected to the speed reducer 3 to transmit force to the motor 2 and is connected to the speed reducer of the motor 2. Two layers of spring steel ring 11 are sleeved on the annular groove outside the docking column 12. After the spring steel ring 11 is aligned with the port of the steel pipe body 1 and pushed in, the spring steel ring 11 expands inside the inner wall of the steel pipe body 1 to achieve the effect of fixing the docking column 12. The other end of the docking column 12 can be selectively installed with a gear, a sprocket, a cam or a multi-wedge pulley according to the actual situation for use in subsequent work, and the installation is convenient.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
