Speaking bearing lubrication, frequently used bearing friends should be aware of its importance, but a lot of people in the lubrication of the bearing operating method is not correct, lead to bearing failure or other problem. Today we'll introduce this knowledge.
Some mechanic install the cylinder pad, like mat coated with a layer of butter in the cylinder, and that this would increase the tightness of the engine.
If the cylinder mat coated with butter, when the cylinder head bolts screwed tight part of the butter is squeezed into the cylinder waterways and oil Road butter remaining in the cylinder head gasket cylinder work, due to the high temperature part of will flows into the cylinder combustion another part will be firing coke deposit on the combination of the surface of the cylinder block and cylinder head, under the action of high pressure and high temperature, easily the cylinder pad breakdown or burn-through, causing the engine leak. Do not install the gasket smear butter.
To prolong its life, we need to pay attention to the day-to-day use and maintenance with a lot of tiny details better maintenance and upkeep of the bearing. When the bearing rotates at high speed, we should take note of what matters. Bearing rotating at high speed, especially speed is close to or exceeds the speed limit described by the size of the table, we should pay attention to the following matters:
1. Bearings should be used in precision bearings;
To analyze the bearing internal clearance; consider and when the temperature rises, imports of bearing internal clearance reduction conditions.
3 Analysis of the type of the material of the bearing cage (for high-speed rotation, is suitable for the use of copper alloy or a phenolic resin cut holder There is also applicable to high-speed rotation of the synthetic resin molding holder);
4. Analysis of bearing lubrication, whether circulating lubrication for high-speed rotation, spray lubrication, oil mist lubrication and oil lubrication lubrication.
