Description

Technical Field

[0001] The utility model relates to the technical field of rotary drive, in particular to a rotary drive with separable inner and outer rings. Background Art

[0002] In the field of mechanical transmission, slewing drive is an important transmission mechanism and is widely used in various equipment that need to achieve 360° full-circle rotation. Traditional slewing drive devices are usually assembled by interference fit, that is, the inner and outer rings are tightly connected through a certain interference fit to ensure the stability and reliability of the transmission. However, this assembly method also brings some problems.

[0003] First, due to the characteristics of interference fit, the connection between the inner and outer rings is very tight, making it extremely difficult to remove or separate them when necessary; this undoubtedly increases the difficulty of repair and maintenance;

[0004] Secondly, since the inner and outer rings are difficult to separate, when dust, impurities or other contaminants accumulate inside the slewing drive, cleaning becomes very difficult. These contaminants not only affect the transmission accuracy and stability of the slewing drive, but may also damage other parts of the equipment, further increasing the failure rate of the equipment.

[0005] Therefore, a separable inner and outer ring type rotary drive is needed to overcome the above-mentioned problems. Utility Model Content

[0006] In order to solve the above problems, the embodiment of the utility model provides a separable inner and outer ring type rotary drive, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: an inner and outer ring separable rotary drive, comprising a base, a roller is rotatably provided on the top of the base, a rotating part is rotatably provided on the top of the roller, and a mounting part is fixedly connected to the top of the rotating part; a driving part meshing with the rotating part is rotatably provided on the base.

[0008] As a further improvement of the above technical solution:

[0009] The top of the base is fixedly connected with a pedestal for accommodating a roller.

[0010] The top and the side of the mounting portion are both provided with mounting positions.

[0011] The mounting portion is fixedly connected to the top of the rotating portion by bolts.

[0012] A rotating shaft is rotatably arranged on the base, and the driving part is installed on the rotating shaft.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] In actual use, the rotating part is placed on the roller and the workpiece is fixed on the mounting part. At this time, the driving part can be used to drive the rotating part, that is, the driving device to rotate; when the rotary drive needs to be cleaned, the rotating part can be directly removed from the roller, and then the roller can be removed from the base for cleaning, which makes it easy to disassemble the rotary drive and thus facilitate the cleaning of the rotary drive.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] See also Figures 1 to 3 The utility model discloses an inner and outer ring separable rotary drive, comprising a base 1, a roller 2 is rotatably provided on the top of the base 1, a rotating part 3 is rotatably provided on the top of the roller 2, and a mounting part 4 is fixedly connected to the top of the rotating part 3; a driving part 8 meshing with the rotating part 3 is rotatably provided on the base 1;

[0021] In actual use, the rotating part 3 is placed on the roller 2, and the workpiece is fixed on the mounting part 4. At this time, the driving part 8 can drive the rotating part 3, that is, the driving device, to rotate; when the rotary drive needs to be cleaned, the rotating part 3 can be directly removed from the roller 2, and then the roller 2 can be removed from the base 1 for cleaning, which is convenient for disassembling the rotary drive, thereby facilitating the cleaning of the rotary drive;

[0022] At the same time, when the workpiece above is too large to be easily transferred, the workpiece can be directly lifted and transferred without the need to disassemble the rotary drive.

[0023] It should be noted that the slewing drive proposed in this application can only be applied to horizontal working conditions.

[0024] As a further illustration of this application:

[0025] A base 5 for accommodating the roller 2 is fixedly connected to the top of the base 1;

[0026] The base 5 can be removed from the base 1, that is, when the groove of the roller 2 is worn and needs to be replaced, the base 5 can be replaced without replacing the entire base 1, thereby reducing maintenance costs;

[0027] The cross section of the mounting portion 4 is L-shaped, and the side of the mounting portion 4 covers the base 5 therein, thereby preventing the rotating portion 3 from being separated from the roller 2.

[0028] As a further illustration of this application:

[0029] The top and the side of the mounting portion 4 are both provided with mounting positions 6 , and the workpiece is mounted on the mounting positions 6 , so that the workpiece can be mounted on the top and the side of the mounting portion 4 , which is convenient for use.

[0030] As a further illustration of this application:

[0031] The mounting portion 4 is fixedly connected to the top of the rotating portion 3 by means of bolts; the mounting portion 4 can be removed from the rotating portion 3 for easy maintenance.
