The tiltable tile bearing is composed of five arc tiles, the upper half bearing is three tiltable tiles, the lower half bearing is two tiltable tiles, the tile can tilt freely on the fulcrum, the tile can swing freely when working, forming a multi-oil wedge around the shaft neck. The lubricating oil of the bearing enters the annular channel of the bearing shell through the oil inlet at the bottom of the bearing. The lubricating oil enters the bearing tile through 5 oil holes from the annular channel. The lubricating oil is distributed along the journal and discharged from both ends of the journal to complete the cooling and lubrication effect.

For bearings used in pairs, excessive axial oil clearance can easily cause cage wear. It is necessary to regularly check the axial movement and adjust it in time. For paired bearings (tapered pairs - DB/DF), the intermediate spacer must be provided by the manufacturer, with high precision, and its main function is to adjust the axial clearance. For example, the suffix T165 means that the total length of the spacer and the bearing is 165mm.

Regarding the damage status of IKO bearings, such as: jamming of the ring ribs of oil-free bearings, the reasons can be considered as insufficient and unsuitable lubricant, defects in the oil supply and drainage structure, foreign matter intrusion, bearing installation errors, and shaft deflection. If the song is too big, these reasons will also overlap. Therefore, it is difficult to know the real cause of the damage only by investigating the bearing damage. However, if you know the machine and operating conditions of the bearing, the structure around the bearing, understand the situation before and after the accident, and investigate the damage status of the bearing and several causes, you can prevent similar accidents from happening again.

The sealing mechanism of the oil seal involves two factors. One is the sealing of the cavity, mainly the positioning of the outer edge of the oil seal (static component) in the cavity; the second is the dynamic seal in which the sealing lip contacts the surface of the rotating shaft, which is the key to the oil seal. The most important function.

Vibration and noise are two major public hazards when construction machinery is working. The engine is the main vibration source of engineering machinery. The propagation of engine vibration directly affects the overall reliability and service life of engineering machinery. It also worsens the driver's riding comfort and reduces work efficiency. Some effective methods must be taken to reduce vibration.
