[0002] A gear is a mechanical component with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting and special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation has received attention.
[0003] Patent No. CN201520423859.3 discloses a sleeve-type large gear, including a gear, which is divided into a support ring and an outer ring. The inner ring of the outer ring is sleeved on the support ring, and a plurality of axially arranged through grooves are distributed on the circumference of the outer ring of the support ring. A plurality of axially arranged protrusions are distributed on the inner ring of the outer ring, and gear teeth are distributed on the outer ring. The through grooves are arranged corresponding to the protrusions, and the protrusions are inserted into the through grooves. A split casting or forging process is adopted, and different materials are used, which reduces the material cost. After the split design, the damaged parts are replaced to reduce waste and reduce the cost of use, thereby solving the problem of high production and use costs of traditional large gears.
[0004] The existing sleeve gear has the following disadvantages: 1. After the sleeve gear is sleeved with the drive shaft, the anti-slip effect is not obvious. For this reason, we propose an anti-slip sleeve gear. Utility Model Content
[0005] The main purpose of the utility model is to provide an anti-slip sleeve gear, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A non-slip sleeve gear comprises a sleeve cap, a gear body and a driving shaft, wherein an axial hole is provided at the axis center of the gear body and limiting grooves are provided at equal distances on the inner wall of the axial hole, a sleeve cap is welded on the top of the gear body and directly opposite to the axial hole, a locking bolt is installed on the top of the sleeve cap through a locking screw hole, a driving shaft is sleeved in the axial hole and limiting blocks corresponding to the limiting grooves are welded at equal distances on the outer side of the driving shaft, and a docking bolt hole is provided on the top of the driving shaft.
[0008] Furthermore, the bottom end of the locking bolt is located in the docking bolt hole at the top of the drive shaft. The locking bolt is screwed downward to allow the locking bolt to enter the docking bolt hole at the top of the drive shaft, thereby limiting the longitudinal position of the drive shaft and preventing shaking, and the anti-slip property is greatly improved.
[0009] Furthermore, the limiting block is located in the limiting groove.
[0010] Furthermore, triangular reinforcement plates are welded at equal distances on the periphery of the connection between the sleeve cap and the gear body.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The utility model is a kind of anti-skid sleeve gear, which utilizes one end of the driving shaft to be sleeved in the shaft hole and the limit block is located in the limit groove, which is convenient for quick sleeve connection and has simple connection steps and significant anti-skid effect. The top end of the driving shaft enters into the sleeve cap and the locking bolt is screwed downward to make the locking bolt enter into the docking bolt hole at the top end of the driving shaft, thereby realizing the longitudinal limitation of the driving shaft and preventing shaking, and the anti-skid property is greatly improved, which is suitable for wide promotion and use.
[0013] 2. The utility model provides an anti-skid sleeve gear, which utilizes triangular reinforcing plates welded at equal distances on the periphery of the connection between the sleeve cap and the gear body to improve the overall strength, rigidity and stability of the sleeve cap.
