Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a highly wear-resistant transmission gear. Background Art

[0002] Transmission gears are a commonly used component in mechanical equipment for transmitting power and changing the speed or direction of movement. They are usually made of metal and have different sizes and shapes to meet various mechanical design requirements. The working principle of transmission gears is to use the meshing between teeth to transmit torque and motion. In mechanical systems, the types and applications of gears are very wide, including spur gears, helical gears, herringbone gears, bevel gears, worm gears, sprockets and chains, synchronous pulleys, etc., among which spur gears are the most common type of gears used for general transmission. Transmission gears are widely used in industries such as industry, automobiles, aerospace, and daily necessities. The correct selection and use of transmission gears is essential to ensure the performance, efficiency and reliability of mechanical equipment.

[0003] When in use, the transmission gear cooperates with the rotating shaft, and the driving device drives the rotating shaft to rotate, the rotating shaft drives the transmission gear to rotate, and the transmission gear drives other parts to move. After the existing transmission gear is connected to the rotating shaft, the rotating shaft drives the transmission gear to rotate for a long time, and the transmission gear will be misaligned with the rotating shaft. The misaligned rotation of the rotating shaft for a long time will increase wear. The greater the wear, the more serious the misalignment. In addition, when the gear is severely worn, the gear cannot be disassembled in a timely and convenient manner, resulting in reduced work efficiency. Utility Model Content
