The bearing for motorcycle is broken, the steering is difficult, the driving is dangerous, and it needs to be repaired in time.
Bearing for motorcycle under normal use does not need to be regularly maintained or greased, as long as the wheel or bearing for motorcycle does not get water, it will be fine for a few years of normal use. Bearing for motorcycle and the mounting base are interference fit, and it often moves it to the wheel It is more troublesome to loose the place where the bearing is installed, and it is more expensive to change the hub or rim. Especially now that most motorcycles use integral aluminum wheels, it will cost at least 200 yuan for a replacement, and a dozen for twenty for a bearing for motorcycle. For a buck, if it breaks, then change it.
Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
According to the different frictional properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger and the price is higher.
Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricant. Mainly with outer ring, inner ring, rolling element can be defined as rolling bearing. According to the shape of rolling elements, rolling bearings are divided into ball bearings and roller bearings
If the bearing for motorcycle is damaged, it is recommended to replace it directly. If it is not replaced, bearing for motorcycle is easy to slip and is dangerous, so it is not worth the loss.
Possible conditions for bearing for motorcycle damage:
1. Running the outer ring directly causes the shaft hole to become larger, so that the hub must be replaced;
2. Run the inner ring and grind the shaft, the same result, the shaft must be replaced;
3. The bearing for motorcycle cage is broken or the roller is broken, and it is forced to drive. Due to the unbalanced rotation, accidents are easy to occur.
Process for testing motorcycle parts:
(1) Front wheel brake. The front wheel brake is operated by the right hand, first check its free travel. The so-called free stroke refers to the stroke from the start of the handle to the start of braking. If the stroke is too small, the front brake shoe and the front wheel brake drum cannot be completely disengaged, which affects the driving speed.
(2) Rear wheel brake. The rear wheel brake is operated by the foot pedal, first check the free travel of the brake pedal.
(3) Clutch. The clutch is generally operated by the left hand, and its free stroke is checked during adjustment.
