Maintenance Skills Of Matching Lubrication Of Ina Thrust Angular Contact Ball Bearing

Maintenance Skills Of Matching Lubrication

The function of bearing matching is to make the stationary ring and Maintenance Skills rotating ring of the bearing consolidate with the stationary part (usually the bearing seat) and the rotating part (usually the shaft) of the installation part respectively,

so as to realize the basic task of transmitting load and defining the position of the moving system relative to the stationary system in the rotating state.

On the shaft and in the bearing pedestal, the thrust angular contact ball bearing is required to fix its Maintenance Skills position in three directions: radial, axial and tangent directions. Radial and tangential positioning is realized through tight fit of INA Bearing Ring,

and tight fit is adopted for axial positioning only in a few cases; Generally, axial limit parts, such as end caps and retaining rings, are used to limit the axial position within the clearance range.

The following four points should be paid attention to when selecting the fit:

(1) The circumferential surface of bearing ring shall have good support and uniform stress to Maintenance Skills reduce deformation and give full play to the bearing capacity of INA Bearing.

(2) The ferrule cannot slide along the tangent direction in its mating surface, otherwise the mating surface will be damaged.

(3) The free end bearing must be able to adapt to the length change of the shaft and bearing seat hole, that is, it must have the ability to Maintenance Skills adapt to the swimming of the axial position within a certain range.

(4) Attention must be paid to making the installation and disassembly of thrust angular Maintenance Skills contact ball bearing simple, labor-saving, time-saving and expenditure saving.

Maintenance Skills Of Matching Lubrication Of Ina Thrust Angular Contact Ball Bearing

Oil bath lubrication is a common lubrication method, which is suitable for the lubrication of low and medium speed bearings.

A part of ina bearing is immersed in the groove, and the lubricating oil is brought up by the rotating bearing Maintenance Skills parts and then flows back to the oil groove. The oil surface should be slightly lower than the center of the low rolling element.

Oil dripping lubrication is suitable for bearing components requiring quantitative supply of lubricating oil. The amount of oil dripping is generally one drop every 3-8 seconds. Excessive amount of oil will increase the bearing temperature.

The filtered oil is transmitted to the bearing parts by the oil pump, and the lubricating oil after contacting the ball bearing through the thrust angle is filtered and cooled before use. Because the circulating oil can take away a certain amount of heat and cool the bearing, this method is suitable for bearing parts with high speed.

The dry compressed air is mixed with the lubricating oil through the sprayer to form an oil mist. In the jet INA bearing, the airflow can Maintenance Skills effectively cool the bearing and prevent impurities from invading. This method is suitable for the lubrication of high-speed and high-temperature bearing parts.

Use the oil pump to shoot the high-pressure oil into the bearing through the nozzle, and the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the thrust angular contact ball bearing rotates at high speed, the rolling element and cage also form air flow around at a fairly high rotation speed.

It is difficult to send the lubricating oil to INA Bearing by general lubrication method. At this time, the lubricating oil must be sprayed into the bearing by high-pressure Maintenance Skills injection method, and the nozzle position should be placed between the inner ring and the center of cage.
