Abstract
Description
Technical Field
[0001] This utility model relates to the field of gears, and in particular to an improved gear. Background Technology
[0002] A gear is a mechanical component that continuously meshes to transmit motion and power. It typically consists of two or more wheels with specific tooth profiles. These wheels mesh with each other, allowing rotational power from one shaft to another, while simultaneously changing speed, torque, or direction of motion. Gears are widely used in various mechanical devices, such as automobiles, watches, and machine tools, and are key components for achieving mechanical transmission and control.
[0003] In the existing technology, although existing gears can transmit power, their overall strength is relatively low. After long-term use, the tooth surface is easily worn severely, or even broken. At the same time, when the gear is subjected to a load that exceeds its design load-bearing capacity or is subjected to a sudden impact load, the overall strength of the gear will be insufficient and it will be damaged, thereby reducing the service life and performance of the gear. Therefore, further improvements to gears are needed. To this end, this utility model proposes an improved gear. Utility Model Content
[0004] The main objective of this invention is to provide an improved gear that can effectively solve the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An improved gear includes a hub with a shaft hole on the front end wall and a keyway on the inner wall of the shaft hole. A spoke plate is fixedly connected to the outer wall of the hub, and a rim is fixedly connected to the outer wall of the spoke plate. A plurality of gear teeth are fixedly connected to the outer wall of the rim in a circular array. The front and rear ends of the rim are respectively provided with a reinforcing mechanism, which includes a reinforcing plate, a reinforcing rib, and a reinforcing tooth plate. Two reinforcing plates are fixedly connected to the front and rear ends of the rim by nuts, and the two reinforcing plates are also sleeved with the hub by inner rings on opposite sides. A plurality of reinforcing ribs are arrayed on the outer wall of the inner ring, and a plurality of reinforcing tooth plates are arrayed on the inner side wall of the reinforcing plate.
[0007] Preferably, a plurality of positioning rods are fixedly installed on the front and rear walls of the plate in a circular array, and the front wall of the positioning rods is provided with a threaded short rod.
[0008] Preferably, the reinforcing plate is provided in a symmetrical set, and the front end wall of the reinforcing plate is provided with a corresponding mounting sleeve hole formed by the shaft hole and the keyway.
[0009] Preferably, the front wall of the reinforcing plate has a positioning hole corresponding to the positioning rod, and the positioning rod is inserted into the positioning hole, and the nut is threadedly connected to the threaded short rod.
[0010] Preferably, the inner sleeve is fixedly installed on the rear wall of the reinforcing plate, and a number of reinforcing ribs are fixedly installed on the annular outer wall of the reinforcing plate in an annular array. The reinforcing ribs are located between the hub and the rim and are in close contact with the surface of the spoke plate.
[0011] Preferably, a plurality of reinforcing toothed plates are fixedly installed in a ring array on the outer annular edge of the rear wall of the reinforcing plate, and the reinforcing toothed plates are located between adjacent toothed plates.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the reinforcing mechanism works in conjunction with the gear. During use, the reinforcing plate is installed on both sides of the gear. During installation, the positioning rod is inserted into the positioning hole on the reinforcing plate, and the inner sleeve is fitted onto the hub. Then, the nut is threaded onto the short threaded rod at the front end of the positioning rod. This secures the reinforcing plate to both sides of the gear. The reinforcing plate prevents wear and damage to the front and rear ends of the gear due to external factors, providing end-face protection. Furthermore, the reinforcing ribs on the outer wall of the inner sleeve, positioned between the hub and the spokes, increase the overall rigidity of the gear structure and resist external loads. The deformation enhances the overall stability and load-bearing capacity of the gear. The reinforcing ribs effectively distribute the immense pressure and torque borne by the gear during operation, preventing deformation or breakage. Furthermore, by placing the teeth between adjacent reinforcing tooth plates, the symmetrical reinforcing tooth plates located at the root of the teeth on both sides provide further support and protection during use, preventing tooth breakage and indirectly enhancing the load-bearing capacity of the teeth. This effectively improves the overall strength of the gear during use, avoiding damage due to insufficient strength, and ultimately extending the gear's service life and performance.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1 - Figure 4 As shown, an improved gear includes a hub 1, a shaft hole 2 is provided on the front end wall of the hub 1, and a keyway 3 is provided on the inner wall of the shaft hole 2. A spoke plate 4 is fixedly connected to the outer wall of the hub 1, and a rim 5 is fixedly connected to the outer wall of the spoke plate 4. A plurality of gear teeth 6 are fixedly connected to the outer wall of the rim 5 in a ring array. The front and rear ends of the rim 5 are respectively provided with a reinforcing mechanism 7, and the reinforcing mechanism 7 includes a reinforcing plate 10, a reinforcing rib 15 and a reinforcing tooth plate 16. The two reinforcing plates 10 are fixedly connected to the front and rear ends of the rim 5 by nuts 13, and the two reinforcing plates 10 are also sleeved together with the hub 1 by inner sleeve rings 14 on opposite sides. A plurality of reinforcing ribs 15 are arrayed on the outer wall of the inner sleeve ring 14, and a plurality of reinforcing tooth plates 16 are arrayed on the inner side wall of the reinforcing plate 10.
[0021] like Figure 2 As shown, several positioning rods 8 are fixedly installed in a ring array on the front and rear walls of the plate 4. The positioning rods 8 are used to cooperate with the reinforcing plate 10 to achieve positioning and installation. The front wall of the positioning rods 8 is provided with threaded short rods 9, which are used to cooperate with nuts 13 to fix the reinforcing plate 10.
[0022] like Figure 3 As shown, the reinforcing plate 10 is provided with a set of symmetrical front and rear. The reinforcing plate 10 can prevent the gear from being worn and damaged by external factors, thus playing a role in end face protection. The front wall of the reinforcing plate 10 is provided with a corresponding mounting sleeve hole 11 formed by the shaft hole 2 and the keyway 3. The mounting sleeve hole 11 is matched with the shaft hole 2 and the keyway 3 to ensure that the gear can be properly installed on the transmission shaft for use.
[0023] like Figure 3As shown, a positioning hole 12 corresponding to the positioning rod 8 is provided on the front wall of the reinforcing plate 10, and the positioning rod 8 is inserted into the positioning hole 12. The nut 13 is threadedly connected to the threaded short rod 9. When installing the reinforcing plate 10, after the positioning rod 8 passes through the positioning hole 12, the nut 13 is threadedly connected to the threaded short rod 9, so that the reinforcing plate 10 can be fixedly installed on the front and rear end faces of the gear.
[0024] like Figure 4 As shown, the inner sleeve 14 is fixedly installed on the rear wall of the reinforcing plate 10, and several reinforcing ribs 15 are fixedly installed on the annular outer wall of the reinforcing plate 10 in an annular array. The reinforcing ribs 15 are located between the hub 1 and the rim 5 and are close to the surface of the spoke plate 4. Through the reinforcing ribs 15 on the outer wall of the inner sleeve 14, and the reinforcing ribs 15 are placed between the hub 1 and the spoke plate 4, the rigidity of the overall gear structure can be increased.
[0025] like Figure 4 As shown, several reinforcing tooth plates 16 are fixedly installed in a ring array on the outer annular edge of the rear wall of the reinforcing plate 10. The reinforcing tooth plates 16 are located between adjacent gear teeth 6, which can further provide support and protection for the gear teeth 6 and prevent the gear teeth 6 from breaking.
[0026] The specific operating principle of the reinforcing mechanism 7 in conjunction with the gear is as follows:
[0027] Before the gear is used, reinforcing plates 10 are installed on the front and rear end walls of the gear. During the installation of the reinforcing plates 10, the positioning rods 8 installed on the front and rear end walls of the flange 4 are inserted into the mounting sleeve holes 11 opened on the front end wall of the corresponding reinforcing plate 10, and the threaded short rods 9 installed on the front end wall of the positioning rods 8 pass through the mounting sleeve holes 11. The nuts 13 are threaded together with the threaded short rods 9 using an auxiliary tool. The nuts 13 are then tightened. In this way, the reinforcing plates 10 can be installed and fixed on the front and rear end faces of the gear. The inner sleeve ring 14 installed on the rear wall of the reinforcing plate 10 will be fitted onto the outer wall of the hub 1. The reinforcing plates 10 can prevent the front and rear end faces of the gear from being worn and damaged by external factors, thus playing a role in end face protection. The reinforcing tooth plate 16 installed on the outer annular edge of the rear end wall of the reinforcing plate 10 will be inserted between several gear teeth 6 installed on the outer wall of the rim 5. When the gear passes through the shaft hole 2 and keyway opened on the front end wall of the hub 1... When the gear is fitted onto the drive shaft using the corresponding mounting holes 11 on the reinforcing plate 10, the reinforcing ribs on the outer wall of the inner ring 14, which are placed between the hub 1 and the spoke plate 4, can increase the rigidity of the overall gear structure and resist external loads and deformation, thereby improving the overall stability and load-bearing capacity of the gear. The reinforcing ribs can also effectively distribute the enormous pressure and torque borne by the gear during operation, preventing deformation or breakage. Furthermore, by placing the gear teeth 6 between adjacent reinforcing tooth plates 16, the symmetrically positioned reinforcing tooth plates 16 at the roots on both sides of the gear teeth 6 can further support and protect them during use, preventing breakage and indirectly enhancing the load-bearing capacity of the gear teeth 6. This effectively improves the overall strength of the gear during use, avoiding damage due to insufficient strength, and ultimately increasing the service life and performance of the gear.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
