How to Improve Bearing Lubrication of Starter

Release date:2019-09-21 10:55 source:Original click:

  Starter bearing (commonly known as copper sleeve), in normal use, often because of its excessive wear and tear and copper sleeve loose, ultimately affecting the performance of starter. There are two main reasons for the easy wear of the starter copper sleeve: one is the large load, which is an unchangeable reality; the other is the poor lubrication, which can be improved. Starter bearing (commonly known as copper sleeve), in normal use, often because of its excessive wear and tear and copper sleeve loose, ultimately affecting the performance of starter. There are two main reasons why the copper sleeve of starter is easy to wear: one is that it bears a large load, which is an unchangeable reality; the other is that the lubrication is poor, which can be improved. The lubrication of copper sleeve and armature Journal of starter is mostly coated with some grease during decomposition and maintenance. Starter can not be lubricated without decomposition in normal use. When the starter works, the outer surface of the journal contacts with all sides of the copper sleeve, which extrudes part of the grease out of the friction surface, accelerates the consumption of grease, causes the dry friction between the journal and the copper sleeve, and aggravates the wear of both. For this reason, two oil grooves with depth of 0.8mm and width of 1.5mm are turned on the inner surface of copper sleeve. The grooves are coated with grease before repairing the starter. The operation test shows that the purpose of long-term lubrication is achieved and the wear of journal and copper sleeve is reduced.
