Questions about the motor bearing ZouDian

Motor bearing ZouDian motor bearing alias rolling bearing, is specialized applied to a kind of special rolling bearing on the motor or motor. Motor application is a strong point of the rolling bearing in the axle parts, it is able to correctly guide shaft rotation, can also undertake the air shaft components, the definition of the rolling bearing is very broad. There are four kinds of the rolling bearing in the motor is common, namely, roller bearing, roller bearing, joint bearing and oil bearing. Production line often encounter power of motor oil condition, it may have very big motor bearing is a leak. In the whole process maintenance maintenance, motor bearing first for maintenance. General will appear the following conditions: 1. Motor bearing pressure difference inside and outside. Mandatory RunHua piston pin, grease itself has certain work pressure, can cause bubbles in the axis runtime oil which causing a certain work pressure. Motor in operation for a cooling fan effect will cause certain negative pressure, and then expand oil inside and outside differential pressure, lead to the oil. In order to better balance the oil inside and outside differential pressure, oil chamber and external drainage riser set up to carry out the pressure balance, but will cause obstruction in the application process, extend oil chamber gas pressure lead to leak. Solution: regular maintenance balanced tube is loose and immediately remove the car fuel tank drainage riser. 2. Steam pressure adjustment is not causing the oil return poorly in a timely manner. Steam pressure too high or too low are can lead to poor oil return. Steam pressure is too low, lead to oil in the oil chamber waiting time too long, cause temperature rise in shaft running process, thus appeared high work stress caused by welding soot; Steam pressure is too high, can make the oil return ability is insufficient, too much oil in the oil chamber, the amount of oil and gas pressure. Solution: adjust the mandatory RunHua work pressure at 0. 1 to 0. 8 mpa, make the oil chamber of the oil level in sight glasses 1/2 ~ 1/3 of the place, and it is advisable to maintain oil return smoothly. 3. Oil return pipe design is not science would lead to poor oil return causing oil pressure of a gas chamber. Oil return pipe of residue or pipeline cleaning not clean is lead to filter block, causing the oil return poorly. The solution: the oil chamber entrance shall be of oil return pipeline oil inlet surface at the same level, all the oil return pipe is under 15 ° inclined to back to the fuel tank, facilitate the return pipe oil return, of course. Also should be timely cleaning filter and all the grease pipe. Above way to reasonably solving general motor bearing oil. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
