Spherical roller bearing lubrication purpose

Bearing - Comfortable and durable - Self-aligning roller bearing electricity department author on July 19th for your explanation: spherical roller bearing lubrication purposes, the main purpose of the lubrication is to reduce friction, and could lead to premature bearing internal wear failure lubrication may be briefly explain the influence of the following: ( 1) Reduce the bearing of direct metal contact between friction and wear of bearing rings, rolling element and cage, this is the basic of spherical roller bearing component by the oil film to prevent the reduce the friction and wear in the contact area. （ 2) Extension of the bearing fatigue life of bearing fatigue life of rolling big rolling contact surface between the viscosity and film thickness. Thick film thickness extend the fatigue life, but if the life extension, will shorten the oil viscosity is too low, so the thickness of the membrane is insufficient. （ 3) Cycle dissipation friction heat and cooling lubrication can be used to carry from external frictional heat or heat check bearing overheating and deterioration. Spherical roller bearing lubrication purpose: plenty of other also helps to prevent foreign material from entering the bearing lubrication and protection device corrosion or rust. Spherical roller bearing lubrication purpose understand we started on a lower roller bearing lubrication methods: all kinds of lubrication method first divided into grease or oil lubrication. Bearing by means of specific performance is the most suitable lubricating methods application and operating conditions. In general, provide excellent lubricating oil; Grease lubrication, however, allows simpler structure around the bearing. More grease and oil lubrication in table 12. 1 is given. Amount of grease to the packing in case depends on the amount of fat in the housing design and free space, oil characteristics and environmental temperature. For example, used in the machine tool spindle bearings, precision may be affected by a temperature rise, only a small amount of grease. Plain bearing in order to determine the number of grease as follows. Bearings must be equipped with enough oil including cage guide surface. Available space within the shell filled with grease can speed is as follows: 1/2 to 2/3 of the space. 。 。 When the speed is less than 50% of the speed limit. 1/3 to 1/2 of the space. 。 。 When the speed is more than 50% of the speed limit bearing comfortable and durable, )
