Description

Technical Field

[0001] The utility model relates to the technical field of rotary drive, in particular to a bipolar rotary drive with input and output on the same side. Background Art

[0002] In the field of industrial automation and precision machinery, the drive system is a key component to achieve efficient and precise operation. Among them, the rotary drive is widely used in various mechanical equipment due to its unique structure and performance. However, the traditional rotary drive design has a significant disadvantage: when the input and output must be located on the same side in special circumstances, the distance between the drive motor and the workpiece becomes relatively small.

[0003] This design limitation has severely restricted the installable size of the workpiece. In practical applications, users need to reserve a certain amount of space for the workpiece so that it can be installed and removed smoothly, so the installable size of the workpiece is relatively small.

[0004] In addition, the small distance between the drive motor and the workpiece may also have an adverse effect on the heat dissipation performance of the equipment.

[0005] Therefore, a bipolar rotary drive with input and output on the same side is needed to overcome the above problems. Utility Model Content

[0006] In order to solve the above problems, the embodiment of the utility model provides a bipolar rotary drive with input and output on the same side, 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: a bipolar rotary drive on the same side of input and output, comprising a shell, a fixed seat is fixedly connected to the inside of the shell, a rotary block is rotatably arranged outside the fixed seat, a driving component for driving the rotary block is also arranged inside the shell, and a transmission component is arranged between the driving component and the rotary block; the transmission component includes a gear 1 that is rotatably arranged inside the shell and meshes with the rotary block.

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

[0009] The driving assembly comprises a rotating shaft rotatably arranged inside the housing and a second gear fixedly connected to the outside of the rotating shaft; the second gear is meshed with the first gear.

[0010] The slewing block is rotatably arranged outside the fixing seat through the volleyball assembly, and the gear 1 is rotatably arranged inside the housing through the bearing.

[0011] The rotary block is provided with a sealing ring 1 located at the gap between the rotary block and the shell, and the rotary block is also provided with a sealing ring 2 located at the gap between the rotary block and the fixed seat.

[0012] The thickness of the sealing ring 1 is greater than the thickness of the sealing ring 2.

[0013] The shell is provided with a heat dissipation protrusion.

[0014] The beneficial effects of the embodiments of the utility model are:

[0015] In actual use, the motor is installed on the drive assembly and the workpiece is installed on the rotating block. In this application, the transmission assembly is used to increase the distance between the drive assembly and the workpiece, thereby increasing the installable size of the workpiece; this application increases the distance between the drive assembly and the rotating block by installing gear one between the drive assembly and the rotating block, and adjusts the transmission ratio between the drive assembly and the rotating block by gear one, thereby changing the output speed and torque.

[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 Figure 1 to Figure 2 The embodiment of the utility model discloses a bipolar rotary drive with input and output on the same side, comprising a housing 1, a fixed seat 2 is fixedly connected to the inside of the housing 1, a rotary block 3 is rotatably arranged outside the fixed seat 2, a driving component 4 for driving the rotary block 3 is also arranged inside the housing 1, and a transmission component 5 is arranged between the driving component 4 and the rotary block 3; the transmission component 5 includes a gear 51 rotatably arranged inside the housing 1 and meshing with the rotary block 3;

[0021] In actual use, the motor is installed on the drive component 4 and the workpiece is installed on the rotating block 3. In this application, the transmission component 5 is used to increase the distance between the drive component 4 and the workpiece, thereby increasing the installable size of the workpiece; in this application, a gear 51 is installed between the drive component 4 and the rotating block 3 to increase the distance between the drive component 4 and the rotating block 3, and the transmission ratio between the drive component 4 and the rotating block 3 is adjusted by the gear 51, thereby changing the output speed and torque.

[0022] As a further illustration of this application:

[0023] The driving assembly 4 includes a rotating shaft 41 rotatably arranged inside the housing 1, and a gear 2 42 fixedly connected to the outside of the rotating shaft 41; the gear 2 42 is meshed with the gear 1 51; the output shaft of the motor is fixedly connected to the rotating shaft 41, and after the motor is started, the gear 2 42 is driven to rotate through the rotating shaft 41, thereby driving the gear 1 51 to rotate, and then driving the rotating block 3 to rotate.

[0024] As a further illustration of this application:

[0025] The rotating block 3 is rotatably arranged on the outside of the fixed seat 2 through the volleyball assembly 6, and the gear 1 51 is rotatably arranged on the inside of the outer shell 1 through the bearing 7; compared with the bearing 7, the volleyball assembly 6 has a larger load, but the installation of the volleyball assembly 6 is relatively cumbersome. In the present application, the rotating block 3 is connected to the workpiece and needs to withstand a larger load. Therefore, the volleyball assembly 6 is arranged between the rotating block 3 and the fixed seat 2 to withstand a larger load. The gear 1 51 does not need to withstand a large load. Therefore, the gear 1 51 and the outer shell 1 are connected through the bearing 7, thereby facilitating the installation and fixation of the gear 1 51.

[0026] As a further illustration of this application:

[0027] The rotary block 3 is provided with a sealing ring 1 8 located at the gap between the rotary block 3 and the housing 1, and the rotary block 3 is also provided with a sealing ring 2 9 located at the gap between the rotary block 3 and the fixed seat 2. The sealing ring 1 8 and the sealing ring 2 9 are used to prevent foreign matter from intruding.

[0028] As a further illustration of this application:

[0029] The thickness of sealing ring 1 8 is greater than that of sealing ring 2 9. The thickness of sealing ring 1 8 is larger, so its deformation under external force is smaller. When used in a high-temperature environment, the interior of the shell 1 requires more lubricating oil for lubrication and cooling. Therefore, a thicker sealing ring 1 8 is set to seal the gap between the rotating block 3 and the shell 1 to avoid lubricating oil leakage; the thickness of sealing ring 2 9 is smaller, so the deformation of sealing ring 2 9 under external force is larger, so that the friction force generated by sealing ring 2 9 is smaller. Since there is no problem of lubricating oil leakage in the gap between the rotating block 3 and the fixed seat 2, a thinner sealing ring 2 9 is set to increase it.

[0030] As a further illustration of this application:

[0031] The housing 1 is provided with a heat dissipation protrusion 10 to improve the heat dissipation effect of the entire device.
