Analysis of the causes of stone crusher bearing lock:
In the actual production process, occasionally there will be stone crusher bearing failure, most of them are caused by human reasons, in addition, because of the quality of machine parts and other factors caused by, but the probability is very small. Because the company is very strict in the use of machine parts, the relevant crusher products are also subjected to strict quality inspection before being handed over to the customer, because the phenomenon of crusher bearing lock caused by quality problems is almost non-existent.
So why will the stone crusher used on the market still have the phenomenon of bearing lock? Let's analyze the relevant factors that may lead to this result from the technical level and improper use:
First of all: there are technical problems in the assembly of the original machine, and the installation is not in place.
1) Improper matching of the bearing outer ring with the bearing seat hole or the bearing inner ring with the shaft during assembly.
If the bearing seat deformation is not found in time, it is easy to cause the outer ring part of the bearing to be squeezed, resulting in the radial clearance of the bearing becoming smaller, the rolling element rotating unevenly, and the wear intensification. In the assembly process, if the bearing assembly is carried out without grinding the inner hole and measuring its size, the temperature will rise after the test. In addition, the bearing inner ring and the shaft clearance is too large, the bearing inner ring with the rolling body and shaft rotation together, there will be unstable rotation problems, a long time after repeated friction, which is easy to cause bearing heat, vibration and abnormal sound.
2) The bearing heating is unstable during assembly.
In the heating operation must prevent the temperature is too high, otherwise it will reduce the hardness and accuracy of the bearing. The increase in bearing temperature will further lead to increased bearing wear and damage. Now that the technology has advanced, the bearing assembly is generally not used in the way of hot processing.
3) There is an obvious problem of improper clearance adjustment of the bearing during assembly.
Shandong Sanxiang Heavy Industry knows that empiricism kills people, and bearing assembly is a very technical work, in the actual operation process, many workers only feel to debug, resulting in too large or too small gaps, completely does not meet the quality requirements. If the axial clearance is too small, it will lead to insufficient heat dissipation space to accelerate the bearing heating, accelerate pitting, and seriously lead to the rolling element stuck or the rubber box damaged; On the contrary, if the axial clearance is too large, it will cause the bearing to clang back and forth, and it can not operate normally according to the predetermined movement track. While accelerating the wear and reducing the stiffness, it will be accompanied by abnormal sound, which will cause serious vibration and even lead to cage damage.
Second: Whether the quality and maintenance of oil seals are in place in time.
In daily production activities, it is necessary to pay attention to whether the sealing degree of the oil seal is good. If there are signs of oil leakage and oil seepage, replace the new oil seal immediately. The oil seal function is used to seal the oil sealing element of the rotating shaft in the mechanical equipment, which plays a dust-proof role and prevents the intrusion of impurities.
Third: Be sure to pay attention to the clearance problem of bearing assembly.
During the assembly process, it is necessary to carefully check the size of the spacer, otherwise the assembly test will be carried out, and the temperature will rise rapidly after a period of operation. The most careless work must be avoided, we must correct our attitude, and all possible accidents should be nipped in the bud as far as possible. The quality of the machine is good or bad from every detail, have done a good job, the overall performance of the machine can certainly be a great step.
Fourth: about the lubrication of machine bearings.
The butter in the crusher bearing is not the more the better, of course, too little is certainly not good. The grease should not be too much, too much grease will increase the friction torque and increase the bearing temperature; However, if the amount of grease is too small, it can not obtain reliable lubrication and dry friction occurs. According to the production experience of Jinbaoshan machinery for many years, the most suitable amount of refueling should be maintained at about two-thirds, and the field staff should pay attention to regular inspection through the excellent observation hole of the machine.
Fifth: Why should this be put in the last, because if it is this reason that the machine's major axis is dead, it should not be. After a period of operation of the general machine, in the normal and maintenance, it is necessary to carry out the relevant oil replenishing work on the machine that needs to be butter from beginning to end, otherwise it is easy to occur because of the lack of lubricating oil in a very short period of time, the bearing and the main shaft in this situation will show purple gray, it is easy to distinguish.
In summary: the crusher produced by Shandong Sanxiang Heavy Industry Co., Ltd. will go through strict quality inspection before leaving the factory, and the bearing damage is rarely caused by technical reasons. In addition, the bearing we cooperate with is a large factory with a good reputation in China, bearing tile box is also Shandong Sanxiang Heavy Industry machinery casting workshop for our production of machines tailored, the installation master is experienced, there is no technical shortboard problems.
