Characteristics of mechanical gear transmission:
A gear is a mechanical transmission in which two gears mesh with each other to transmit power and movement. 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 a device that directly transmits motion and power with the teeth of the main and driven wheels. It can be used to transmit the motion and power between two axes that are not far away from each other.
The characteristics of gear transmission are: stable transmission, accurate transmission ratio, reliable operation, compact structure, high efficiency, long service life, wide range of power, speed and size. For example, the transmission of power transmission can be a very small hundreds of thousands of kilowatts, the speed can be as high as 300 meters / second, the diameter of the gear can range from a few millimeters to more than twenty meters, but special equipment is required to manufacture the gear, and the mesh The drive will produce noise.
Characteristics of mechanical sprocket transmission:
The sprocket transmission is suitable for transmission with a large center distance, and it has light weight. The processing accuracy and installation accuracy of the chain and sprocket and the accuracy of the center distance in the sprocket transmission are lower than the gear requirements, and their installation and maintenance are also simpler and more convenient. Normally, sprockets have sprocket teeth and chains engaged at the same time, and the sprocket tooth groove arc is large and the gear stress concentration is small. Therefore, the load capacity of the sprocket is higher and the surface wear of the gear teeth is relatively light. Since the chain has good elasticity, and each hinge part of the chain can store lubricating oil, compared with the rigid contact gear teeth, the sprocket has better buffering capacity and vibration absorption capacity.
