Description

Technical Field

[0001] This utility model relates to the field of gear technology, specifically to a gear with double teeth. Background Technology

[0002] A double gear is two gears connected as one unit. In a gear train, this type of double gear is called a sliding gear. Its function is to change the rotational speed or speed of the output shaft. In a gearbox, there are multiple rotational speeds or speeds if there is a sliding gear, and only one rotational speed or speed if there is no sliding gear.

[0003] A search revealed that patent application CN208107101U discloses a double gear, including a first gear and a second gear fixed to the bottom of the first gear. A shaft hole for inserting a gear shaft is provided between the first gear and the second gear. The first gear and the second gear are integrally formed. The first gear and the second gear are made of metal. By integrally forming the first gear and the second gear with metal materials, the problem of misalignment and wobbling of the first gear and the second gear when wear occurs between the gear and the gear shaft can be effectively solved.

[0004] However, since the first and second gears are molded as a single piece, when one of the gears is damaged, the entire gear needs to be replaced. The first and second gears cannot be disassembled and separated, resulting in high maintenance costs and inconvenient installation and disassembly. In addition, since the first and second gears are connected by threads alone, the connection stability is low, and loosening is likely to occur after long-term use, making the installation unstable.

[0005] Therefore, we propose a gear with double teeth. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a gear with double teeth, which solves the problems of inconvenient installation and disassembly and low connection firmness of the existing device.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a gear with double teeth, including a gear shaft A, wherein a gear shaft B of the same specifications is assembled on the left side of the gear shaft A;

[0008] Gears A are evenly distributed and fixedly installed on the outer wall of gear shaft A. Gears B are evenly distributed and fixedly installed on the outer wall of gear shaft B. A through mounting hole is provided on the left side of gear shaft A, and the mounting hole is adapted to the specifications of gear shaft B. A thread A is provided on the outer wall of the right end of gear shaft B. A locking nut of the same specifications is fitted on the right side of gear shaft A. The right end of gear shaft B protrudes from gear shaft A. A thread B of the same specifications is provided on the inner wall of locking nut.

[0009] A limiting sleeve with opposite positions is fixedly installed on the outer wall of the gear shaft B. Four sets of corresponding locking blocks are fixedly installed on the right side of the limiting sleeve. Four sets of corresponding locking grooves are opened on the left side of the gear shaft A. An annular groove A is opened on the left side of the locking nut. A washer of the same specification is fitted in the groove A. A groove B of the same specification is opened on the right side of the gear shaft A.

[0010] Preferably, a through hole is provided on the left side of the gear shaft B, so that gear shaft A and gear shaft B can share a single hole, ensuring the integrity of the hole and improving its performance.

[0011] Preferably, the washer is made of rubber material, which can improve the performance of the washer and prevent the washer from damaging the gear shaft B and the lock nut.

[0012] Preferably, the locking nut is hexagonal, which makes it easy to rotate the locking nut with a wrench.

[0013] Preferably, the outer walls of gear shaft A and gear shaft B are fitted with a corrosion-resistant layer, which is a zinc-plated layer, thereby improving the corrosion resistance of gear shaft A and gear shaft B.

[0014] Preferably, the mounting holes, shaft holes, gear A, and gear B are coated with titanium carbide, which can improve their wear resistance and thus increase their service life.

[0015] 1. This type of gear with double teeth, through the setting of gear shaft A, gear shaft B and mounting hole, the gear shaft B is inserted into the mounting hole, and then the gear shaft A and gear shaft B are connected and fixed by locking nut. The installation and disassembly are simple and convenient. When gear A or gear B is damaged, only the gear shaft to which it is located needs to be replaced, reducing maintenance costs.

[0016] 2. Simultaneously, through the setting of the locking block, the locking groove, and the washer, when the gear shaft B is inserted into the mounting hole, the locking block is inserted into the locking groove, which can prevent the gear shaft A and gear shaft B from rotating relative to each other. When the locking nut is rotated and installed on the gear shaft B, the washer can improve the friction between the locking nut and the gear shaft B and the stability of the connection, ensuring a firm installation.
