Description

Technical Field

[0001] This utility model belongs to the field of gears, and relates to a gear, and more particularly to a split gear. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. Gears are toothed mechanical parts that can mesh with each other, and they are indispensable parts in industrial machinery.

[0003] Most existing gears are cast in one piece. This means that when a tooth breaks or wears down and can no longer mesh with other gears, the gear is rendered unusable and needs to be replaced, while the gear body remains intact. This results in waste, increased operating costs, and increased frequency of gear replacement, placing a burden on maintenance personnel.

[0004] For example, a gear according to patent number 202223154514.1 includes a gear and a central ring. The gear ring is sleeved on the central ring. One side of the central ring is a first surface, and several first holes are formed on the first surface. Teeth are distributed on the outer wall of the gear ring. The first surface is flush with one end face of the gear or located between the planes containing the two end faces of the gear. The first surface no longer protrudes from the two end faces of the gear, so when the drilling device drills the first holes, it only needs to control the drilling head to be located outside the end face of the gear ring, without needing to move it to the central ring for a lifting operation.

[0005] In the aforementioned patent, the teeth and the tooth ring are still designed as an integrated unit. When the teeth are damaged, the tooth ring and the central ring will be rendered unusable due to the damage to the teeth, increasing the cost of use. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in the prior art by providing a split gear that facilitates tooth replacement.

[0007] This utility model can be achieved through the following technical solution: a split gear, including a main body, an installation groove on the main body, teeth installed in the installation groove, a connecting block at the bottom of the teeth, a positioning block in the installation groove, a positioning groove on the connecting block, a locking hole on one side of the installation groove, and a limiting rod extending from one side of the connecting block, the limiting rod being inserted into the locking hole.

[0008] In the aforementioned split gear, a fixing groove is provided at the locking hole, and a fixing block is installed on the fixing groove.

[0009] In the aforementioned split gear, a filling portion extends from the fixing block, a protruding plate extends from the filling portion, and a groove is formed on the connecting block.

[0010] In the aforementioned split gear, sliding plates are provided on both sides of the connecting block, and sliding grooves are provided on the mounting slot.

[0011] In the aforementioned split gear, the fixing block extends to a mounting plate, the mounting plate has a through hole, and a screw passes through the through hole and the fixing groove.

[0012] In the aforementioned split gear, a limiting hole is provided on the fixing block.

[0013] Compared with the prior art, the advantages of this utility model are as follows: the original integrated gear is split into a split gear composed of teeth and gear body. The teeth and gear body are manufactured and assembled separately. When one or more teeth are damaged, the teeth can be replaced, reducing the cost of use. At the same time, when the gear body is damaged, the teeth can be disassembled and stored. The teeth are connected to the gear body through independent fixing blocks, which facilitates the replacement of a single tooth when damaged, improving maintenance efficiency.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figures 1 to 3 As shown, the present invention can be realized through the following embodiments: a split gear includes a main body 1, an installation groove 11 is provided on the main body 1, a tooth 2 is installed in the installation groove 11, a connecting block 21 is provided at the bottom of the tooth 2, a positioning block 3 is provided in the installation groove 11, a positioning groove 22 is provided on the connecting block 21, a locking hole 12 is provided on one side of the installation groove 11, and a limiting rod 23 extends from one side of the connecting block 21 and is inserted into the locking hole 12.

[0017] The main body 1 mounts the tooth 2 through the mounting groove 11, making it easy to replace the tooth 2 when it is damaged; the connecting block 21 is used to connect the tooth 2 and the mounting groove 11, while the positioning block 3 and the positioning groove 22 facilitate the transmission of the force from the shaft hole of the main body 1 to the tooth 2, and at the same time prevent the tooth 2 from accidentally falling off; the limiting rod 23 is inserted into the locking hole 12 to prevent the tooth 2 from falling off from the opening of the mounting groove 11.

[0018] like Figure 1 As shown, a fixing groove 4 is provided at the card hole 12, and a fixing block 5 is installed on the fixing groove 4. The fixing block 5 is installed on the fixing groove 4 to fix the tooth 2 and the main body 1, preventing the tooth 2 from falling off. At the same time, after removing the fixing block 5, it is convenient to replace a single tooth 2.

[0019] like Figure 1 and Figure 3 As shown, a filling part 51 extends from the fixing block 5, and a protruding plate 52 extends from the filling part 51. A groove 24 is provided on the connecting block 21. The filling part 51 is provided to fill the opening of the fixing groove 4 and fill the space above the card hole 12, thereby restricting the sliding of the limiting rod 23 up and down, so as to achieve the purpose of fixing the tooth 2. The protruding plate 52 cooperates with the groove 24 to increase the contact surface between the fixing block 5 and the tooth 2, and prevent the limiting rod 23 from deforming due to excessive pressure.

[0020] like Figure 1 and Figure 2 As shown, sliding plates 25 are provided on both sides of the connecting block 21, and sliding grooves 13 are provided on the mounting groove 11. The sliding plates 25 and sliding grooves 13 cooperate to guide the connecting block 21 into the mounting groove 11, improving assembly efficiency.

[0021] like Figure 1 and Figure 3 As shown, the fixing block 5 extends to a mounting plate 53, which has a through hole 55. A screw 6 passes through the through hole 55 and the fixing groove 4. The screw 6 passes through the through hole 55 to fix the fixing block 5 and the main body 1, making it convenient for the user to disassemble and install the fixing block 5.

[0022] like Figure 1 and Figure 3 As shown, a limiting hole 54 is provided on the fixing block 5. The limiting hole 54 is provided so that the limiting rod 23 can pass into the fixing block 5, limiting the displacement of the limiting rod 23, and thus limiting the displacement of the tooth 2. In conjunction with the fixing hole, the tooth 2 is fixed to the main body 1 by the screw 6 to prevent it from falling out. The working principle of this utility model is as follows: After assembling the tooth 2, the main body 1 and the fixing block 5, if the tooth 2 is damaged, unscrew the bolt, remove the fixing block 5 from the fixing groove 4, slide the tooth 2 to remove the tooth 2 from the mounting groove 11, and put the new tooth 2 into the mounting groove 11. Finally, reverse the above steps.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0024] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
