The front and rear wheel bearings of the bicycle bearing ball are all rotated by the outer ring, which is equivalent to a double row angular contact ball bearing to a certain extent. The rear wheel bearing mainly bears its rotating load during operation, and the front wheel bearing is mainly used when in use. With a fixed load, the bicycle is a chain drive, the ankle drives the front sprocket, and the rear sprocket is transmitted to the rear sprocket. The chain gives the rear wheel a torque, which drives the rear wheel to rotate. The rear wheel is fixed with the outer ring of the bearing, and the steel ball rotates and revolves. The inner ring is still.
The forward force of the bicycle bearing ball gives the front wheel a torque. When the operation, the front wheel bearing outer ring rotates together with the front wheel. During the operation, the auto-transmission of the steel ball will be revolved and effectively walk forward. When turning, the front wheel bearing is subjected to tilting torque on one side.
The bicycle bearing ball determines the relative position of the two parts and ensures their free rotation, simultaneously transmitting the load between them during operation. At high speeds (for example in gyro ball bearings), the use can be expanded to include free rotation. There is almost no wear in the bearings. To achieve this, the two parts of the bearing can be separated by a layer of adhesive fluid film called an elastic hydrodynamic lubricating film.
