Jia VS Sprockets

China Gears

murasilẹ

  • The gear is involute tooth shape, while the sprocket is “three arcs and a straight line” tooth shape.
  • Gears are driven by meshing the teeth of two gears, while two sprockets are driven by chains.
  • Gear can realize the transmission between parallel axes and any staggered axes, while sprocket can only realize the transmission between parallel axes.
  • The torque transmitted by gears is larger than that of sprockets.
  • The processing accuracy and installation cost of gears are higher than that of sprockets.
  • Gear transmission is compact, while sprocket can realize long-distance transmission.
China Sprockets

Sprockets

  • Chain drive is suitable for transmission with large center distance, and has the characteristics of light weight and low cost.
  • The processing accuracy and installation accuracy of chain and sprocket as well as the accuracy of center distance in chain drive are less than that of gears, and it is easier to change the parameters of existing chain drive (transmission ratio, center distance, etc.) for easy installation and maintenance.
  • Usually, the chain drive has higher sprocket wheel teeth and chain simultaneously participate in the meshing and the sprocket teeth groove arc, the gear stress concentration is small, therefore, the chain drive has a large load-bearing capacity, and the gear tooth surface wear is relatively light.
  • Because the chain has good elasticity and each hinge part of the chain can store lubricating oil, it has better buffering capacity and vibration absorption capacity compared with the rigid contact gear teeth.
  • When the transmission capacity is limited by space, the center distance is small, the instantaneous transmission ratio is constant, or the transmission ratio is too large, the speed is very high, and the noise requirement is small, the performance of chain transmission is not as good as that of gear transmission.
