The Cause Of Damaged Automotive Bearing

- Dec 24, 2017 -

Bearing is a precision part, so it requires a very cautious attitude when it is used. That is to say, a high performance bearing is used. If it is not used properly, it will not achieve the expected performance effect, and it will easily damage the bearing. Therefore, the use of bearings should pay attention to the following items:

1. Keep the bearings and their surroundings clean

Even if the invisible smile dust enters the bearing, it will increase the wear, vibration and noise of the bearing.

Two. Be careful and careful when using the installation

Strong punching is not allowed, the hammer is not allowed to strike the bearing directly, and the pressure is not allowed through the rolling body.

Three. Use appropriate and accurate installation tools

Try to use special tools to avoid the use of cloth and short fiber.

Four, to prevent the corrosion of the bearing

When you directly take the bearings by hand, you must wash away the sweat from your hands and put them in high-quality mineral oil before you operate. In the rainy season and summer, you should pay special attention to rust prevention.

However, under some special operating conditions, the bearing can get longer than the traditional computing life, especially in light load conditions. These special operation conditions are that the rolling surface (track and rolling part) is effectively separated by a lubricating oil film and the surface damage caused by pollutants can be restricted. In fact, under ideal conditions, the so-called permanent bearing life is possible.

Bearing life

The life of rolling bearings is defined as revolutions (or hours of work at a certain speed), and the initial fatigue damage (spalling or defect) of bearing on any bearing ring or rolling element should be defined. However, no matter in laboratory test or in actual use, it can be seen clearly that under the same working conditions, the same appearance and bearing life are quite different. In addition to several different definitions of bearings "life", one of the so-called "working life", it represents the actual life of a bearing can be reached in damage before by the wear and tear, damage is usually caused not by fatigue, but by abrasion, corrosion, sealing damage and other causes.

Why does the bearing wear damage?

Only part of the bearing is damaged in the actual application.

There are many reasons for the damage of most of the bearings - more than the previously estimated load, non - effective seal, tight fit caused by the small bearing clearance, etc. Any of these factors have special damage patterns and leave special damage marks. Therefore, to examine the damage to the shaft bearing, in most cases it may cause can be found, in general, 1/3 of the bearing damage due to fatigue damage, another 1/3 due to bad lubrication, the other 1/3 due to improper handling or installation of pollutants into the bearings.

However, these types of damage are also related to industrial categories. For example, more than half and half of pulp and paper industry are caused by bad lubrication or pollution, not due to material fatigue.
