Bearing lubrication

Core Tip: The purpose of bearing lubrication: The purpose of lubrication of rolling bearings is to reduce the internal friction and wear of the bearing, to prevent burning, and its lubricating effect is as follows. (1) Reduce friction and wear. In the formation of bearings
The purpose of bearing lubrication:
    The purpose of lubrication of rolling bearings is to reduce internal friction and wear of the bearings, to prevent sticking, and the lubricating effect is as follows.
    (1) Reduce friction and wear.
    In the mutual contact portion of the ferrule, the rolling element and the retainer constituting the bearing, metal contact is prevented, and friction and wear are reduced.
    (2), prolong the fatigue life.
    The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low and the thickness of the lubricating oil film is not good, it is shortened.
    (3), discharge friction heat, cooling.
The circulation oil supply method or the like can be used to discharge heat generated by friction or heat from the outside to cool. Prevent the bearing from overheating and prevent the lubricant from aging itself.
    (4), other
    There is also the effect of preventing foreign matter from entering the inside of the bearing or preventing rust and corrosion.
    Lubrication method:
    The lubrication method of the bearing is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose a lubrication method that suits the conditions of use and the purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the bearing and comparing the advantages and disadvantages of grease lubrication and oil lubrication.

Cylindrical Roller Bearings
    The cylindrical roller is in line contact with the raceway, and has a large radial load capacity, which is suitable for bearing heavy loads and impact loads. It is also suitable for high-speed rotation of N-type and NU-type axial movement, and can be adapted to thermal expansion or installation error. The change of the relative position between the shaft and the outer casing is most suitable for the free end bearing type NJ and NF type to withstand a certain degree of unidirectional axial load. The NH type and NUP type can withstand a certain degree of bidirectional axial load inner or outer ring. Separable, easy to assemble and disassemble NNU type and NN type, strong rigidity against radial load, mostly used for machine tool spindle
    Mainly applicable cages:
    Steel stamping cage (Z-shaped), copper alloy cutting cage, pin cage, synthetic resin forming cage
    The main purpose:
    Medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading machinery, various industrial machinery
    Solid needle roller bearing
    The basic structure of the inner ring bearing is the same as that of the NU type cylindrical roller bearing, but due to the use of the needle roller, the volume can be reduced, and the large radial load can be withstood without the inner ring bearing. The mounting surface of the shaft with appropriate precision and hardness should be used as the mounting surface. Raceway surface
    Mainly applicable cages:
    Steel stamping cage
    The main purpose:
    Automotive engines, transmissions, pumps, excavator track wheels, hoists, overhead cranes, compressors

The processing of the main parts of the bearing

Core tips: 1. The processing of the ferrule: the processing of the inner ring and the outer ring of the bearing differs depending on the raw material or the form of the blank. The process before the machining can be divided into the following three types, the whole process
 1. The processing of the ferrule: The processing of the inner and outer rings of the bearing varies according to the raw material or the form of the blank. The process before the machining can be divided into the following three types. The whole processing process is: bar or pipe material (Some bars need to be forged and annealed, normalized)----Car processing----heat treatment----grinding----finishing or polishing----final inspection of parts---- Anti-rust----into the warehouse----(to be combined with the package)

    2. The processing of the steel ball, the processing of the steel ball also varies according to the state of the raw material, wherein the process before the frustration or the photosphere can be divided into the following three types, the process before the heat treatment, and can be further divided into the following Two kinds, the whole processing process is: bar material or wire cold punching (some bars need to be punched and annealed after cold pressing)----frustration, rough grinding, soft grinding or light ball----heat treatment- --- Hard grinding----fine grinding----finishing or grinding----final inspection group----rust prevention, packaging----into the warehouse <to be combined with the package>.

    3. The processing of the roller during the processing of the roller varies according to the raw material. The process before the heat treatment can be divided into the following two types. The whole processing process is as follows: the bar processing or the cold rolling of the wire after the string ring and the soft grinding ----Heat treatment----string soft point----grinding outer diameter----grinding end face----finishing end face----fine grinding outer diameter----finishing outer diameter ---- Final inspection group----rust prevention, packaging----into the warehouse (to be combined with the package).

    4. Processing of the cage The processing of the cage can be divided into the following two categories depending on the design structure and raw materials:

    (1) Sheet → shear → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be combined)
    (2) Processing process of solid cage: The processing of solid cage varies according to raw materials or gross damage. The following four types of blanks can be divided into the following processing: The bar is Pipe, forgings, castings----car inner diameter, outer diameter, end face, chamfering----drilling (or pulling holes, boring)----pickling----final inspection---- Anti-rust, packaging----into the warehouse.
