Demand review tool on the form of running, the thrust ball bearing in the two-way is the focus of everyones attention, and preparing a full review plan has become more and more important. KA bearings
But not all of the tools are equipped with this conservative facility.
Low temperature often indicates that the bearing is in a strange situation.
Two-way thrust ball bearings are in the process of running, and sometimes the name of the bearings will be squeezed between the domestic soft particles or hard foreign bodies or non-metallic wear debris, which will be bearing the formation of furrow-shaped scratches, the Department of soft foreign body smooth The media into the bearing outside, with the bearing from time to time running, all the conflict heat, easy to form the collision surface of all the deformation and micro-welding phenomenon of conflict, as well as the emergence of all the ablation of the situation, the initial occlusion scene. Bearing broken and the two major causes of overload and overload, when the additional load beyond the limits of personnel strength and the formation of the whole break is called overload fracture, is the process of two-way thrust ball bearings will also occur overheating institutions and all burns shortcomings, causing shortcomings Broken.
. Caused by the causes of low-temperature bearings include: more than smooth or too smooth, smooth agent. The deformity of the bearing is measured by the heat quantity, heat dissipation, speed and load of the tool.
Two-way thrust ball bearing measurement, the normal bearing room inside the measurement can be guessed, if the application of oil holes can be indirectly measured bearing outer ring measurement, the more suitable. Low temperature is also harmless to the bearing smooth agent.
The use of thermal sensors can always monitor the two-way thrust ball bearing the task of measurement, and complete the measurement beyond the value of the initiative when the alarm or suspend the fire shaft incident.
The use of two-way thrust ball bearings with the bearing to determine the heat of the process, the conventional heat treatment process to measure the tempering temperature of 150 degrees, the highest use of the bearing normal request is 120 degrees, if there is a special application request, to adopt 250, or more, when the gas gauge can reach 170,230 degrees or more. Because it is the most important morphological monitoring of all-around bending elements to prevent bearing protection in order to prevent out-of-program repair facilities during downtime to form a late stage of bearing protection that is being made at home once in the main group. In this case, the tool operator or maintenance engineer must maintain the bearing fault signal alarm. Normal we can go through the instrument to review the situation attributed to the break, a large number of cases, the majority of bearing breaking effect of the overload caused by the entry into force. Containing impurities, the load is too large, bearing loss ring, more than the gap, and the occurrence of high-friction oil seals and the like. If the two-way thrust ball bearings are measured beyond 125 ℃ temporary transfer will increase bearing life. If the smooth, the Department of equipment for the bearing temperature will be a sharp decline in the emergence of abnormal low temperature, then the need to suspend operation, take the extra precautionary measures.
In general, two-way thrust ball bearings with the bearings measured the beginning of the operation gradually decreased, 1-2 hours after reaching the solid form. Sometimes bearing overheating can be attributed to the smooth lubricant bearing.
