Description

Technical Field

[0001] This invention relates to the field of gear technology, and more particularly to an end face gear with preload. Background Technology

[0002] A face gear is a type of gear that meshes with a spur gear or helical gear at a 90-degree axial angle. The central axes of the pinion and the face gear are perpendicular, and the two perpendicular central axes can intersect or be offset. Face gears are mainly used in industries such as helicopters, fishing reels, watches, and bicycles. Due to their heavy-duty and smooth transmission characteristics, they have a wide range of applications. Some devices require a series of auxiliary machines to operate. Although there are many ways to connect the main unit and the auxiliary machines, they are generally contact connections, which involve the meshing of end-face gears and other gear components. This type of connection is usually rigid, which leads to noise and vibration during the connection process. In particular, during gear meshing, the tolerance between the meshing teeth causes tooth breakage during linkage drive, affecting normal and stable operation. Therefore, this invention proposes an end-face gear with preload to solve the problems existing in the prior art. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a preloaded end face gear. This preloaded end face gear is composed of a gear body and a gear ring. The insert rod of the gear ring is built into the slot of the gear body. An elastic element supports the insert rod on one side, giving the insert rod a certain unidirectional preload, so that the entire gear ring has a preload, which acts on the meshing teeth, ensuring that the meshing teeth maintain tight meshing with other compatible gears and avoiding tooth breakage.

[0004] To achieve the objective of this invention, the invention is implemented through the following technical solution: an end face gear with preload force, comprising a gear body and a gear ring, wherein a slot is provided at the top edge of the gear body, and a rod is provided at the bottom edge of the gear ring, the rod being inserted into the interior of the slot, and a limiting ring is provided at the lower end of the rod, the limiting ring being limited inside the gear body, and meshing teeth are provided at the top edge of the gear ring; One side of the slot is provided with an elastic element.

The side cavity is provided with a worm that is adapted to the worm gear. The worm is provided with a helical gear, and the front end of the helical gear passes through the gear body.

[0005] A further improvement is that the elastic element includes a support piece and a spring piece, the spring piece being located on one side of the support piece and the screw rod being located on the other side of the support piece.

[0006] A further improvement is that the spring sheet is provided in multiple sets, and the multiple sets of spring sheets form a wave shape.

[0007] A further improvement is that: at least four sets of slots are provided, and multiple sets of the four sets of slots are provided at equal included angles around the center of the gear body, and at least four sets of insertion rods are provided.

[0008] A further improvement is that the helical gear is adapted to the driving component, the driving component is a rotating ring, and the inner side of the rotating ring is provided with internal teeth, which are adapted to the helical gear.

[0009] A further improvement is that the gear ring, insert rod, and limiting ring are integrally formed, and the gear body, gear ring, insert rod, limiting ring, and meshing teeth are all made of alloy.

[0010] A further improvement is that the inner side of the limiting ring extends through the slot, and the inner side of the limiting ring and the inner side of the gear body are located on the same plane.

[0011] A further improvement is that the bottom of the gear ring and the top of the gear body are fitted together, and both the bottom of the gear ring and the top of the gear body are smooth surfaces.

These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example 1

The insert rod 4 of the gear ring 2 is built into the slot 3 of the gear body 1. The insert rod 4 is supported on one side by an elastic element, and a certain unidirectional preload is applied to the insert rod 4, so that the gear ring 2 as a whole has a preload, which acts on the meshing teeth 6, so that the meshing teeth 6 maintain a tight mesh with other matching gears and avoid tooth breakage. By rotating the helical gear 12, the worm gear 11 can be rotated, which causes the worm wheel 10 and the nut tube 8 to rotate, driving the screw rod 9 and the elastic element for fine adjustment, making it easy to change the preload and making the use more reliable.

[0021] The elastic element includes a support plate 13 and spring plates 14. The spring plates 14 are located on one side of the support plate 13, and the screw rod 9 is located on the other side of the support plate 13. Multiple sets of spring plates 14 are provided, and these sets form a wave shape. The wave shape of the multiple sets of spring plates 14, in conjunction with the support plate 13, constitutes the elastic element. The spring plates 14 support each other, providing sufficient elasticity and resistance to deformation. The spring plates 14 support the insertion rod 4 on one side, providing a certain unidirectional preload, thus ensuring that the gear ring 2 as a whole has a preload, which acts on the meshing teeth 6, ensuring that the meshing teeth 6 maintain tight engagement with other compatible gears and preventing tooth breakage.

[0022] The slots 3 are provided in four sets, and the four sets of slots 3 are arranged at equal included angles around the center of the gear body 1. The insertion rods 4 are provided in four sets. Through the combination of the gear body 1 and the gear ring 2, the insertion rods 4 of the gear ring 2 are built into the slots 3 of the gear body 1. The insertion rods 4 are supported on one side by elastic elements, and a certain unidirectional preload is given to the insertion rods 4. From four directions, the gear ring 2 as a whole has a preload, which acts on the meshing teeth 6, so that the meshing teeth 6 maintain a tight mesh with other matching gears and avoid tooth breakage. Example 2

[0023] according to Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, this embodiment proposes an end face gear with preload force, including a gear body 1 and a gear ring 2. The gear body 1 has a slot 3 at the top edge and a rod 4 at the bottom edge of the gear ring 2. The rod 4 is used to insert into the slot 3, and the lower end of the rod 4 is provided with a limiting ring 5, which is limited inside the gear body 1.

The insert rod 4 of the gear ring 2 is built into the slot 3 of the gear body 1. The insert rod 4 is supported on one side by an elastic element, and a certain unidirectional preload is applied to the insert rod 4, so that the gear ring 2 as a whole has a preload, which acts on the meshing teeth 6, so that the meshing teeth 6 maintain a tight mesh with other matching gears and avoid tooth breakage. By rotating the helical gear 12, the worm gear 11 can be rotated, which causes the worm wheel 10 and the nut tube 8 to rotate, driving the screw rod 9 and the elastic element for fine adjustment, making it easy to change the preload and making the use more reliable.

[0024] The helical gear 12 is adapted to the driving component, which is a rotating ring 15. The inner side of the rotating ring 15 is provided with internal teeth, which are adapted to the helical gear 12. By rotating the specially designed rotating ring 15 in conjunction with the internal teeth, four sets of helical gears 12 can be driven synchronously, which facilitates the simultaneous adjustment of the preload of four sets of elastic elements, making it more convenient and stable to use.

[0025] The gear ring 2, insert rod 4, and limiting ring 5 are integrally formed, and the gear body 1, gear ring 2, insert rod 4, limiting ring 5, and meshing teeth 6 are all made of alloy, making them more robust.

[0026] The inner side of the limiting ring 5 extends through the slot 3, and the inner side of the limiting ring 5 and the inner side of the gear body 1 are on the same plane. This alignment of the inner sides facilitates mounting on other support shafts.

The insert rod 4 is supported on one side by an elastic element, giving the insert rod 4 a certain unidirectional preload, so that the gear ring 2 as a whole has a preload, which acts on the meshing teeth 6, so that the meshing teeth 6 maintain tight meshing with other matching gears and avoid tooth breakage. By rotating the helical gear 12, the worm gear 11 can be rotated, causing the worm wheel 10 and the nut tube 8 to rotate, driving the screw rod 9 and the elastic element for fine adjustment, which is convenient for changing the preload and makes the use more reliable. In addition, the present invention uses multiple sets of spring pieces 14 to form a wave shape, which, together with the support plate 13, constitutes an elastic element. The spring pieces 14 support each other, which is highly elastic and not easily deformed.
