Now we are in the direction of the market proportion is higher and higher, the point of view of market should not be ignored, some other people in bing's opportunistic opportunity, as well as counterfeit products and systems. From personal experience to the service life of the rolling bearing, the influence of many factors can be used to further illustrate factors and internal factors.
Use direction adjustment factors, mainly in the installation and maintenance, repair and maintenance in accordance with technical requirements. According to the installation guide, technology use, maintenance, maintenance work, as a guide, support a work load, speed, temperature, vibration, noise and condition inspection and monitoring, found that abnormal lubrication, adjustment seek immediate return to normal. Installation conditions of use is one of the primary factor, bearing factor is usually by the installation direction, is not appropriate to ShouLi change direction between the parts do not work in normal state, and complete before the service life of the main factors, namely in the structure design, manufacturing and quality of the three factors on the quality of the material such as decision relevance.
(a) to guide the burden
Choose to load type of guidance, common burden rolling, pure axial thrust bearing. Charge to choose the most pure thrust ball axis; Choose in pure big goods
All Kinds Of Size Of SKF Bearing. Generally speaking, pure radial load direction choose deep groove ball bearings, cylindrical roller needles or direction. Radial direction in the interview, and r. small load of axial options, deep groove ball angular contact ball bearing roller contact or guidelines; Guidance or when the spear, the charge can take the choice of larger angular contact ball bearings, or perhaps the roller bearing thrust bearing and guide together, ChengDang different axial load and radial load.
(2) the direction of rotation
In general, the selection of the speed type attack speed of the buyer, without affecting the biggest competitor, velocity have obvious influence. Direction into the sample values of type, size, direction of the speed limit. This refers to the speed is not too great a burden (P 0.1 C or less, this is for the extra burden basic normal, cooling), as long as the level 0 is most relevant and rotating commitments.
(3) XinGongNeng guidance
When the boundaries between, shaft bearing the line in the middle of the error and does not match the point of view, ShouLi or shaft, game, bending or training opportunities of PianXie one axis direction. Then, must take certain XinGongNeng self-aligning ball bearing roller bearing or heart. This correlation circles may be less PianXie axis can work normally.
Cylinder needles in the direction and the guiding significance of PianXie more sensitive to the correlation in ideology PianXie pick up the ball, in the course. Multiple spindle stiffness and bearing hole low stiffness, support should be as far as possible to stop this guidance.
4) guiding device and destruction
To shut down and full of choice type guide you must think that when shooting a element. In bearings Pou point without bread to destroy and equipment, components - guide the spark, must pay attention to cycle could choose BieLi N0000, NA0000 as a guide, (3), and so on. When facilities on the axis line length, in order to facilitate tear open outfit, can choose to make the circle / 1:12 (hole equipment set TAB to close direction.)
The guidance of quality material is metallurgical rolling the correlation of the main factors influencing the early failure. As the technology (such as iron and steel metallurgy vacuum direction, etc.) gas raw material progress, improve quality. In proportion to the raw material quality factor analysis of the failure handling has been greatly reduced, but is still one of the main influence factors of failure dependency. If still XuanCai appropriate guidance must consider factors analysis of the failure.
Total direction by forging, treatment, bending, machining and assembly, and multiprogramming. The rationality of the process, will also affect the stability and advancement in the life of the bearing. In product quality and the process of thermal effect of rolling bearing, is often the most direct relationship with the bearing failure. In recent years, research shows that waste layer of the surface of the work direction is close to the surface quality of process and related.
Life analysis is the main task of the guidance, a large number of data, analysis, find out the failure of the background and the main factors related to failure, in order to put forward the improvement measures, to extend the orientation degree is differ, there are sudden, prevent premature failure of the bearing.
