Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, specifically to a novel rotating mechanism. Background Technology

[0002] In many mechanical devices, rotating mechanisms are common and key components used to achieve the rotational movement of parts. Traditional rotating mechanisms typically use a motor to directly drive the shaft rotation, or achieve rotation through simple gear meshing. For example, in some simple rotating devices, the motor's output shaft is directly connected to the part that needs to rotate. This method is simple in structure, but it is somewhat insufficient in some scenarios that require complex motion transmission or high rotational accuracy.

[0003] The shortcomings of existing technology:

[0004] 1. Friction Issues: Existing rotating mechanisms often experience significant friction between components during rotation. For example, when a motor directly drives a shaft, friction between the shaft and the supporting structure is unavoidable. This friction increases energy loss because some electrical energy is converted into heat, reducing the motor's transmission efficiency. Furthermore, prolonged friction can lead to component wear, affecting the service life and accuracy of the rotating mechanism.

[0005] 2. Motion Transmission Accuracy Issues: In some traditional gear-driven rotary mechanisms, the meshing precision between gears is difficult to guarantee. If the gears are not machined with high precision or their installation positions are off, inaccurate motion transmission will result. For example, in high-precision machining equipment or rotating processes in automated production lines, the inability to precisely control the rotation angle and speed will affect the quality of the entire production process.

[0006] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a novel rotating mechanism.

[0008] To achieve the above objectives, the specific solution of this utility model is as follows:

[0009] This utility model provides a novel rotating mechanism, comprising:

[0010] Drive mechanism, ring-shaped component, moving parts;

[0011] The annular component is fitted onto the movable component;

[0012] A strip-shaped groove is provided on the outer wall of the movable part along its axial direction;

[0013] The inner wall of the annular part is provided with a protrusion, which is embedded in the strip groove;

[0014] The drive mechanism is used to drive the ring-shaped component to rotate, which in turn drives the movable component to rotate.

[0015] Furthermore, the drive mechanism is connected to the ring-shaped component via a belt, thereby driving the ring-shaped component to rotate, and the ring-shaped component driving the movable component to rotate.

[0016] Furthermore, the drive mechanism includes a motor and gears;

[0017] A toothed ring is also provided on the outer wall of the annular component;

[0018] The gear is mounted on the output shaft of the motor, and the gear meshes with the toothed ring on the outer wall of the ring component for transmission.

[0019] The motor drives the gear to rotate, which in turn drives the ring to rotate. The protrusion on the inner wall of the ring is embedded in the strip groove of the movable part. The side wall of the strip groove abuts against the protrusion. By restricting the circumferential displacement of the protrusion, the ring drives the movable part to rotate.

[0020] Furthermore, the protrusion is composed of a roller and a rotating shaft;

[0021] The roller is rotatably mounted on the rotating shaft, which is installed on the inner wall of the annular component;

[0022] The axis of the roller is perpendicular to the axis of the moving part;

[0023] The roller is embedded in the strip groove, and the outer circumferential surface of the roller contacts the side wall of the strip groove to drive the moving part to rotate.

[0024] Furthermore, the number of the strip grooves is four, each strip groove is evenly distributed along the circumference of the movable part, and each strip groove is provided with a protrusion.

[0025] Furthermore, the four strip-shaped grooves are spaced 90 degrees apart from each other in the circumferential direction of the moving part.

[0026] Furthermore, the movable component has a cylindrical structure.

[0027] Furthermore, the rotating mechanism also includes a battery that is electrically connected to the motor.

[0028] The technical solution of this utility model has the following beneficial effects:

[0029] 1. Reduce friction

[0030] This novel rotating mechanism employs a design where rollers are embedded in strip-shaped grooves. The rollers are rotatably mounted on the rotating shaft, with their outer circumferential surfaces contacting the sidewalls of the grooves. This rolling contact method significantly reduces friction, effectively minimizing energy loss and improving the device's transmission efficiency compared to traditional sliding friction. It also helps extend the service life of components and reduce maintenance costs.

[0031] 2. Precise motion transmission

[0032] The motor drives the gear to rotate, and the gear meshes with the gear ring to drive the rotation of the ring component. The protrusions (rollers) on the inner wall of the ring component are embedded in the strip grooves of the moving component. The sidewalls of the strip grooves abut against the protrusions, which can precisely limit the circumferential displacement of the protrusions. This allows for precise control of the rotation angle and speed of the moving component, ensuring the accuracy of motion transmission. It is suitable for applications requiring high rotational precision.

[0033] 3. Stable and reliable structure

[0034] The moving parts have a cylindrical structure, which provides high strength and stability, enabling them to withstand certain radial and axial loads and ensuring the stability and reliability of the entire rotating mechanism during operation. Furthermore, the four strip-shaped grooves are evenly distributed along the circumference of the moving parts at 90-degree intervals, resulting in more uniform force distribution and further enhancing the stability of the mechanism, preventing vibration and deformation caused by uneven force distribution.

[0045] Combination Figures 1-4 As shown, this utility model provides a novel rotating mechanism, comprising:

[0046] Drive mechanism, ring component 3, moving component 4;

[0047] The annular component 3 is fitted onto the movable component 4;

[0048] A strip-shaped groove 9 is provided on the outer wall of the movable part 4 along its axial direction;

[0049] The inner wall of the annular part 3 is provided with a protrusion, which is embedded in the strip groove 9;

[0050] The driving mechanism is used to drive the ring part 3 to rotate, and then drive the movable part 4 to rotate through the ring part 3.

[0051] The drive mechanism is connected to the ring component 3 via a belt, which in turn drives the ring component 3 to rotate, and the ring component 3 drives the movable component 4 to rotate.

[0052] The drive mechanism includes a motor 1 and a gear 2;

[0053] A toothed ring 5 is also provided on the outer wall of the annular component 3;

[0054] The gear 2 is mounted on the output shaft of the motor 1, and the gear 2 meshes with the toothed ring 5 on the outer wall of the ring 3 for transmission.

[0055] The motor 1 drives the gear 2 to rotate, which in turn drives the annular part 3 to rotate. The protrusion on the inner wall of the annular part 3 is embedded in the strip groove 9 of the movable part 4. The side wall of the strip groove 9 abuts against the protrusion. By restricting the circumferential displacement of the protrusion, the annular part 3 drives the movable part 4 to rotate.

[0056] The protrusion is composed of a roller 6 and a rotating shaft 7;

[0057] The roller 6 is rotatably sleeved on the rotating shaft 7, and the rotating shaft 7 is installed on the inner wall of the annular part 3;

[0058] The axis of the roller 6 is perpendicular to the axis of the movable part 4;

[0059] The roller 6 is embedded in the strip groove 9, and the outer peripheral surface of the roller 6 contacts the side wall of the strip groove 9 to drive the movable part 4 to rotate.

[0060] The number of the strip grooves 9 is four, and each strip groove 9 is evenly distributed along the circumference of the movable part 4. Each strip groove 9 is provided with a protrusion.

[0061] The four strip-shaped grooves 9 are spaced 90 degrees apart from each other in the circumferential direction of the movable part 4.

[0062] The movable component 4 has a cylindrical structure.

[0063] The rotating mechanism also includes a battery 8, which is electrically connected to the motor 1.

[0064] The principle of this utility model is as follows:

[0065] Power input phase:

[0066] After the motor 1 (which can be powered by battery 8) is started, it drives the gear 2 on its output shaft to rotate.

[0067] Ring-shaped component transmission stage:

[0068] Gear 2 meshes with the toothed ring 5 on the outer wall of the ring part 3, transmitting rotational motion to the ring part 3, causing the ring part 3 to rotate around its own axis.

[0069] Motion conversion and torque transmission stage:

[0070] The protrusion on the inner wall of the annular part 3 (the core structure is a roller 6 with a rotating shaft 7) is embedded in the strip groove 9 on the outer wall of the movable part 4:

[0071] The axis of roller 6 is perpendicular to the axis of moving part 4;

[0072] When the annular part 3 rotates, the circumferential displacement of the protrusion (roller 6) is restricted by the sidewall of the strip groove 9;

[0073] The outer circumferential surface of roller 6 forms a rolling contact with the side wall of the groove, pushing the side wall of the groove to move.

[0074] Active component driven phase:

[0075] The sidewall of the groove bears the circumferential thrust of the roller 6, which transmits the torque to the movable part 4, forcing the movable part 4 to rotate synchronously with the ring part 3.

[0076] Load sharing and stability assurance:

[0077] Four strip-shaped grooves 9 are evenly distributed around the movable part 4 (at 90° intervals), and each groove contains a roller 6;

[0078] Four-point synchronous drive disperses the load, avoiding stress concentration at a single point and improving transmission smoothness.

[0079] Axial degree of freedom preserved:

[0080] The design of the strip groove 9 extending along the axial direction of the movable part 4 allows the movable part 4 to freely extend, retract, or move along the axial direction while rotating, without being constrained by the ring part 3.

[0081] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
