There are dozens of cars bearing is rolling bearing, DU bushing greatly small almost include all common bearing type, rolling bearing of the hit and damage is also more common. Because of rolling bearings are generally is packed in internal institutions,Mould guide plate so inconvenience intuitive check, can according to the fault phenomenon first as general judgment, then remove the check.
Proper use of rolling bearing is to reduce bearing fault, plasic bushing extend the reliable guarantee of bearing life, which include the correct installation and reasonable lubrication. Below are introduced the use of rolling bearing requirements and common faults,plain bearing damage.
A, the rolling bearing used correctly
1. Bearing tear open outfit
Bearings shall be cleaned before installation. When installed, brass bushing should use a special tool will ChengPing straight uniform pressure into the auxiliary, don't use hammer percussion, particularly prohibit direct in bearing on percussion. When the bearing cast bronze loops and a hole with loose, shall repair a hole or replace bearing, do not use in bearing on the surface with hemp dot or pad TongPi method to use force. Remove the bearing should be used when appropriate,bronze bushing will pull the bearing, do not use the chisel, hammer, striking the bearings.
2. Bearing lubrication
The rolling bearing commonly used lubricant oil and grease have two. When the circumference of the shaft speed less than 4-5 m/s, or cars can't use lubricating oil, the position isdry bushing lubricated by grease. Grease lubrication is sealed the advantages of simple structure, grease not easy loss, effected by temperature is not big, add a grease can use a long time.
Use a grease to pay attention to two questions, sleeve bushing one is to follow your car manual request, choose the right type of grease. For example, the water pump bearing is unfavorable choose and manufactured on, because of its water resistance is poor. 2 it is to join the bearing grease want right amount, average filling bearing the cavity 1/2-l / 3 advisable, too much useless not only, bushing still can increase bearing operation resistance,Solid Bronze Bushing make warming fever. Special attention should be paid to is car wheel bearing, want to advocate "empty hub lubrication", that is only in bearing of layer of the tu yi on a moderate amount of grease can,Sintered Bronze Bushing otherwise, not only waste heat and bad, still can make heat grease spill, which may affect the braking performance.
The advantages of the lubricating oil is friction small resistance, and can heat dissipation, mainly used for high speed and working environment high temperature of the bearings. Bronze Bar Oil's brand according to the requirements of the car manual selection, Cast Bronze Sleeve and car maintenance cycle change in time, let out the old oil to clean institutions added again new oil, the oil should be added to the provisions of the line, or and refueling leveled mouth, not more.
