Features of mechanical gear transmission:
A gear is a mechanical transmission where two gears mesh with each other to transmit power and motion. The relative positions of the gear shafts are divided into parallel-shaft cylindrical gear transmission, intersecting-shaft bevel gear transmission, and staggered-shaft helical gear transmission. It has the characteristics of compact structure, high efficiency and long service life.
Gear transmission refers to the device that directly transmits motion and power by the teeth of the driving and driven wheels. Can be used to transmit motion and power between two axes that are not far from each other.
The characteristics of gear transmission are: stable transmission, accurate transmission ratio, reliable work, compact structure, high efficiency, long service life, wide range of power, speed and size. For example, the transmission of power can be extremely small hundreds of thousands of kilowatts, the speed can be as high as 300 meters per second, the diameter of the gear can range from a few millimeters to more than twenty meters, but special equipment is needed to make the gears, and The drive will make noise.
Characteristics of mechanical sprocket drive:
The sprocket transmission is suitable for transmission with a large center distance, and it has light weight. In the sprocket drive, the machining and installation accuracy of the chain and sprocket, and the accuracy of the center distance are lower than the requirements of the gear, and its installation and maintenance are also simpler and more convenient. Generally, a sprocket has both sprocket teeth and a chain participating in the meshing at the same time, and the sprocket cogging arc is large, and the stress concentration of the gear is small. Therefore, the sprocket has a higher bearing capacity and the surface of the gear teeth is relatively light. Because the chain has better elasticity, and each hinge part of the chain can store lubricating oil, compared with rigid contact gear teeth, the sprocket's buffering capacity and vibration absorption capacity are better.
