      The function of the thrust bearing is to withstand the axial thrust of the rotor during operation, and to determine and maintain the axial mutual position between the turbine rotor and the cylinder. The thrust bearing can be set as a separate type, or it can be combined with the supporting bearing, which is called a combined type. According to the structural shape, it can be divided into multi-jaw type and fan-shaped tile type. Now the fan-shaped tile type is generally used. The main structure of the thrust bearing is composed of working tiles, non-working tiles, adjusting gaskets, mounting rings, etc. Ten to twelve working tiles and non-working tiles are respectively installed on both sides of the thrust plate, each tile is installed on the mounting ring, the working tiles bear the positive axial thrust of the rotor, and the non-working tiles bear the reverse thrust of the rotor. Axial thrust.

Separable bearings are composed of raceway rings, needle rollers and cage components, which can be combined with thin raceway rings processed by stamping or thick raceway rings processed by cutting. Non-separable bearings are made of rollers processed by precision stamping The integral bearing composed of raceway ring, needle roller and cage assembly can withstand unidirectional axial load. This type of bearing occupies a small space and is conducive to the compact design of machinery. Most of them only use needle roller and cage assembly, and the shaft And the mounting surface of the housing is used as the raceway surface. It is mainly suitable for steel stamping cages and synthetic resin molded cages. Main application: transmission devices for automobiles, cultivators, machine tools, etc.

      Plane thrust needle roller bearings consist of a thrust cage with needle rollers and a thrust washer. The needle rollers are held and guided by thrust cages. The thrust needle roller and cage assembly is the main element of the thrust needle roller bearing. The needle rollers are held and guided by radially arranged pockets. The cage profile has a specific shape and is formed using hardened steel strips. The small size cage is made of industrial plastic. With thrust function, axial load, low speed, deflection possible

Thrust needle roller bearing features:

Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings , the outer diameter is small, especially suitable for bearings with limited radial installation dimensions. According to different application occasions, the bearing without inner ring or the needle roller and cage assembly can be selected. At this time, the journal surface and the shell hole surface matching the bearing are directly used as the inner and outer rolling surfaces of the bearing, which is the same as the load capacity and running performance. Bearings with rings are the same, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This kind of bearing can only bear radial load.

Product features of thrust needle roller bearings:

When used with different series of thrust bearing washers, many different combinations are available for bearing configurations. When the surface of the adjacent parts is suitable for the raceway surface, the gasket can be omitted, so that the design is compact. The needle roller and the cylindrical roller surface of the thrust needle roller bearing are modified surfaces, which can reduce the edge stress and improve the service life.

High-precision needle rollers can be selected to increase the contact length, so that the bearing can obtain high load capacity and high rigidity in a small space. The dimensional tolerances, geometric accuracy, rigidity, axial runout, and roughness of the shaft shoulder end surface of the installation component and the bottom surface of the housing hole should meet international standards.

The main application of thrust needle roller bearings:

Elevator Parts Plastic Machinery Office Equipment Medical Equipment

Stepper Motors Speed Reduction Devices Pressure Rotors Fitness and Sports Equipment
