The gear box is spindle and perpendicular to the ground, the shaft axial force, low speed and high torque, behind the tapered roller bearing is mainly cage is always damaged, damaged, please brother cause analysis, I have no wealth value of Big Brother Big Sister please help analyze the reasons
A look at whether the seal is not good, into the dust, sand and gravel and so on, two to see whether the quality of bearing itself, you can replace with imported bearings try.
Bearing damage in many ways, a large part of the reason is the improper installation method. Another part may be impurities in the bearings. For example: scrap iron, particles, dust and so on. There may be bearings are fake, can not meet the use requirements. Of course, do not rule out the initial selection of irrational factors. You can look at your own situation and see where the problem is.
Bearing damage should be a lot of ah!! There are two main aspects!!First, the use of your bearings unreasonable, such as installation problems, there is no reasonable installation, this will check whether the correct installation of bearings! There is no attention to protect the use of bearings, like some of the dust into the bearing, leading to damage to bearings, but also may be the operation of the machine itself! Cause the bearings to work in an irrational working environment! Which causes the bearings to be damaged easily!Another is that you buy the bearings themselves, the quality of the problem!! There's no way out! Ha-ha！！ Check to see if you have bought a fake or something!! In that case, you can only replace one of the bearing suppliers! Ha-ha！ I didn't know where you bought it! I know that there is an import bearing agent, called Ao Sheng Mechanical bearings, is Japan's MSRHK import bearings of the general agent! Our company has been carrying bearings there! There's no big quality problem. You can find out about them!! Ha-ha！ They also have an official website!
Possible causes:1, because of the excessive use of bearings and poor oil quality, resulting in fatigue damage to the ball bearing materials until the fragmentation. The oil in the gear box may also be dirty.2, there are problems of excessive tolerance of journal dimensions and excessive preload of bearings.Solving measures:1, adjust the thickness of the end cover gasket2, not to catch the schedule and increase the load, to avoid mechanical fatigue damage accidents.3, the main moving parts, especially bearings, should do a good job of time statistics, if omitted, should promptly correct, to avoid the use of parts overtime.4, do a good bearing spare parts inventory, records, light consumption of important bearings, should promptly apply for order.
