Description

Technical Field

[0001] This utility model relates to the field of TPU gear rotation technology, specifically, to a TPU gear rotation device. Background Technology

[0002] Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, or TPU for short, is an (AB)n-type block linear polymer. A is a high molecular weight polyester or polyether (1000-6000), and B is a diol containing 2-12 straight-chain carbon atoms. The chemical structure between the AB segments is a diisocyanate. Thermoplastic polyurethane rubber is cross-linked by intermolecular hydrogen bonds or by slight cross-linking between macromolecular chains. These two cross-linking structures are reversible as the temperature increases or decreases.

[0003] However, the existing gear rotation device has poor compatibility between the support component and the gear assembly, which makes the gear prone to axial movement or radial displacement during rotation, making it impossible to achieve precise multi-gear rotation. Therefore, those skilled in the art provide a TPU gear rotation device to solve the problems mentioned in the background art. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-3 As shown, this utility model provides a technical solution: a TPU gear rotating device, including a support assembly 1 for supporting rotation, a gear assembly 2 for matching and rotating the support assembly 1 on one side, the support assembly 1 including a first upper cover 11, a rib 12 slidably connected to the inner cavity of the first upper cover 11 near the gear assembly 2, a first lower cover 13 fixedly connected to the lower end of the first upper cover 11, a limiting groove 14 formed in the inner cavity of the first lower cover 13 near the rib 12, and the gear assembly 2 including a first TPU gear 21. Wheel 21 is rotatably connected to the outside of rib 12. The side of the first TPU gear 21 away from the support component 1 is rotatably connected to the second TPU gear 22, and the second TPU gear 22 is rotatably connected to the outside of rib 12. The upper ends of the first TPU gear 21 and the second TPU gear 22 are rotatably connected to the second upper cover 23, and the second upper cover 23 is tightly connected to one side of the first upper cover 11. The lower ends of the first TPU gear 21 and the second TPU gear 22 are rotatably connected to the second lower cover 24, and the second lower cover 24 is fixed to one side of the first lower cover 13 by screws.

[0016] The support component 1 provides a stable base for the rotation of the gear assembly 2. The first upper cover 11 and the first lower cover 13 are fixed by screws. The four circular ribs 12 that are slidably connected on the side of the gear assembly 2 cooperate with the limiting groove 14 in the inner cavity of the first lower cover 13 to achieve their own positional stability. On the other hand, they provide rotational support for the first TPU gear 21 and the second TPU gear 22 of the gear assembly 2. At the same time, the inner grooves of the second upper cover 23 and the second lower cover 24, which are matched with the thickness of the first and second TPU gears 22, limit the axial displacement of the gears and reduce frictional loss. The uniformly distributed annular mounting holes with internal threads on the bottom of the first lower cover 13 and the second lower cover 24 can be used to fix the device to external equipment or platforms with bolts. Finally, the gear assembly 2 can achieve stable 360° multi-gear rotation with the support component 1.

[0017] As one implementation method in this embodiment, please refer to Figures 1-3As shown, the first TPU gear 21 has a 40-tooth design, which can achieve 40 rotations within a 360° range, with each gear having a rotation angle of 9°. The second TPU gear 22 has a 16-tooth design, which can achieve 16 rotations within a 360° range, with each gear having a rotation angle of 22.5°.

[0018] The first TPU gear 21 has a 40-tooth design. When the device is running, it rotates around the rib 12 of the support component 1. With the structural characteristics of 40 teeth, it can achieve 40 precise rotations within a 360° rotation range. By converting 360° to 40 gears, the rotation angle corresponding to each gear is 9°. The second TPU gear 22, which works in conjunction with it, has a 16-tooth design and also rotates around the rib 12. With the structure of 16 teeth, it can achieve 16 rotations within a 360° rotation range. The rotation angle of each gear is calculated to be 22.5°. The two TPU gears achieve different gears and angles of rotation through different tooth numbers.

[0019] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the first upper cover 11 and the first lower cover 13 are fixed together by screws.

[0020] The first upper cover 11 and the first lower cover 13 are fixed together by screws to form a stable supporting base structure.

[0021] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the inner sides of the second upper cover 23 and the second lower cover 24 are provided with slots that are adapted to the first TPU gear 21 and the second TPU gear 22, and the depth of the slots matches the thickness of the first TPU gear 21 and the second TPU gear 22.

[0022] Both have slots on their inner sides that are compatible with the first TPU gear 21 and the second TPU gear 22, and the depth of the slots is precisely matched with the thickness of the two TPU gears. This structural design can axially limit the first TPU gear 21 and the second TPU gear 22 from the top and bottom, preventing the gears from moving up and down during rotation around the rib 12, thus ensuring that the first TPU gear 21 and the second TPU gear 22 can complete multi-gear rotation actions stably and smoothly.

[0023] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the rib 12 is made of hard plastic, which is strong enough to support the stable rotation of the gear assembly 2 and the fixed gear position.

[0024] The rib 12, as a key connecting support component between the support component 1 and the gear component 2, is made of hard plastic material with sufficient strength to support the stable rotation of the gear component 2. It has reliable structural strength and can stably bear the force generated when the first TPU gear 21 and the second TPU gear 22 rotate around it, avoiding deformation or breakage due to insufficient material strength, and ensuring the structural stability of the gear during rotation.

[0025] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the inner cavity at the bottom of the first lower cover 13 and the second lower cover 24 is provided with a slot for locking, and the diameter of the slot is adapted to the specifications of the locking connector, and the depth of the slot is sufficient to allow the connector to be fully embedded without protruding from the bottom of the first lower cover 13 and the second lower cover 24.

[0026] The interlocking slots formed in the bottom cavities of the first lower cover 13 and the second lower cover 24 are a key design feature for achieving overall structural fixation and external installation compatibility of the device. Their diameters precisely match the specifications of the interlocking connectors, ensuring that the connectors can be stably embedded in the slots and reliably interlock. This guarantees the stability of the connection between the first lower cover 13 and the first upper cover 11 in the support assembly 1, and between the second lower cover 24 and the second upper cover 23 in the gear assembly 2, thus laying the foundation for the stable support of the gear assembly 2 by the support assembly 1.

[0027] Working principle: The device is based on the support component 1 as the basic support structure. The first upper cover 11 and the first lower cover 13 are fixed by screws. The four circular ribs 12 that are slidably connected on the side of the two near the gear assembly 2 not only cooperate with the limiting groove 14 in the inner cavity of the first lower cover 13 to achieve their own positional stability, but also provide rotational support for the gear assembly 2. In the gear assembly 2, the first TPU gear 21 with 40 teeth can achieve 40 gears of rotation within a 360° range, and the second TPU gear 22 with 16 teeth can achieve 16 gears of rotation within a 360° range. Both of them rotate around the ribs 12. At the same time, the grooves opened on the inner side of the second upper cover 23 and the second lower cover 24 are matched with the gear thickness, which restricts the axial displacement of the gear and reduces frictional loss. Finally, the gear assembly 2 can achieve stable multi-gear rotation under the coordinated cooperation of the multiple structures of the support component 1.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
