Function that FAG needle bearing cooperates with lubricating oil

7th December 2013 Bearing Technology 0 Comments

FAG function that bearing cooperate to make resting cycle sum of needle bearing rotate enclose respectively and resting part pedestal usually to install placement And rotating part usually the axle The concretion together, thus realize that transmits the load and limits the basic task relative to position of resting system of the remote action system in rotating state.

On the axle and in the pedestal, the antifriction bearing is required in three directions such as the radial, axial and tangent direction are fixed, his positioned. Radial and tangent alignment are adopted and realizes through the close fit to the bearing ring, position and adopt the close fit only under a few situations axially; Usually adopt the axial limit location part, for instance end cap and retaining ring,etc. restrict the axial position to backlash range.

FAG bearing should pay attention to the following four points while choosing to cooperate

The intersection of bearing ring and round periphery should have, support and force even while being good, in order to reduce out of shape can give full play to the intersection of FAG and bearing capacity of bearinging;

The bearing ring can’t be slipped in the direction of tangent in it cooperates with the surface, otherwise will damage the fitting surface;

The freedom end bearing must be able to accommodate the axle and length change in the bearing seat hole, must meet the ability to move about within the specific limits in the axial position;

Must make needle bearing install and dismantle simple and convenient, accomplish labour saving, saves time, the expenses of province.

It is very beneficial to make good use of the cooperation function of the needle bearing, hope for four above attentive matters of overall consideration during application of everybody too.

To already bearing and double-sided to oil seals or dust caps that lipoprotein lubricate, the seal ring FAG bearing does not need to wash before installation. Check the size of the relevant part and finish the situation.

1,The grease is lubricated

FAG bearing lubricate, implement at time when the project apparatus shuts down preferably again, go on, supplement regularly, meanwhile, remove old oil or via let out empty to crowd the old oil out oil. Should polish the pump nozzle clean before adding the fresh oil. If the bearing housing does not have pump nozzle, should turn on the case lid of the bearing or end cap, in order to take out old oil, clear up, supplementary the same fresh oil of type.

2,Lubricate the oil lubrication

Check oil level and oil of the lubricating oil regularly, generally speaking, the normal oil level should be in Windows of oil level of an apparatus or 1/3-2/3 of the ranges labelled. Oil makeup way belong to lubricator, its expicity oil level only represents ability of oil makeup, and bearing housing oil level to meet service requirement, the intersection of oil level and less than its full-size 1/4 can consider oil makeup in the lubricator.

The method of oil makeup of check sum, the lubricating oil which is taken out drib is compared with fresh lubricating oil as the sample, the capable unit can consider testing the oil, so as to ensure the oil is qualified. If the sample seems to be the cloud vaporifically, it then may be a result mixed with water, that is to say the oil which everybody often says is emulsified, should change the lubricating oil at this moment.

If sample melanized or thickening Cheng thick, may then show the lubricating oil has already begun carbonization, should change the old lubricating oil completely. If it is possible, would use the fresh lubricating oil to develop the oil passage. While changing the lubricating oil, should guarantee new, old types of lubricating oil changed are the same, and the oil level of meeting the demands supplemented.

Use the oil bath type lubricating system, if the oil warm 140 degrees Fahrenheit at 60 ℃Following, and the lubricating oil is not polluted, change lubricating oil once a year. If the oil is warm at 60-100 ℃’ 140-210 degrees Fahrenheit ,Need to change the biquadratic lubricating oil in one year. If the oil is warm at 100-120 ℃’ 210-250 degrees Fahrenheit ,Need to change lubricating oil once per month. If the oil is warm at 120 ℃’ 250 degrees Fahrenheit The above, need to change lubricating oil once every week.
