Proper lubrication and maintenance can play bearing the highest service life.
1, the grease lubrication
Bearing relubrication is best during the implementation of the planned equipment downtime, and re gularly supplement the same time, the old grease is removed through the drain empty crowding out the old grease. Before adding fresh oil should be injection nozzle wipe clean. If the bearing housing is not the injection nozzle, and add the same type of bearing cover or end cap should be open in order to remove the old grease, clean, fresh grease.angular contact bearings
2, the lubricating oil
Regularly check the oil level and oil quality of the lubricant, under normal circumstances, the normal oil level should be 1/3-2/3 of the range equipment oil window or marked. Up the oil by the oil cup, which shows the oil represents fill the oil capacity, the oil level of the bearing housing to meet operational requirements, oil cup, oil level is lower than the total volume of 1/4 can be considered to make up the oil.
Check and fill oil, remove the small amount of lubri cating oil samples and fresh lubricant to compare the ability of the units can be considered for oil testing to ensure that the oil qualified. If the sample appears cloudy, then the results may be mixed with water is often said that the oil emulsion, lubricating oil should be replaced. If the sample Cheng darker colors or thickens, it may be that the oil has begun to carbonation, the old grease should be completely replaced. If possible, use fresh oil on the oil flushing. Replacement of oil, should ensure that the new replacement oil, the same old models and added to meet the requirements of the oil level.roller bearing
Oil-bath lubrication system, if the oil temperature below 60 ° C (140 ° F), and the lubricating oil is not contaminated and replaced once a year lubricants can. If the oil temperature in the 60-100 ℃ (140-210 ° F), year to replace the four lubricants. If the oil temperature in the 100-120 ° C (210-250 ° F) per month need to replace a lubricant. If the temperature is above 120 ° C (250 ° F), the weekly needs to be replaced once a lubricant.
Correct installation and maintenance is an important factor bearing the normal operation of the same time, we must pay attention to maintaining the cleanliness of the bearings. Bearing the need to prevent pollution by contaminants and moisture, must have the correct installation and lubrication. In addition, the bearing with the column design, and oil seal, the lubricant in the form of maintenance and replacement cycle and expertise also play an important role, must be concerned.
A starting torque, starting torque
A bearing ring or gasket for another fixed ring or washer begins to rotate the desired torque.stainless steel ball bearings
&n bsp;(2) rotary torque running torque
When the rotation of a bearing ring or gasket to prevent another ring or gasket movement of the torque required.
(3) radial load to radial load
Acting on the vertical bearing axis line direction of the load.
The axial load axial load
Role in parallel to the bearing axis line direction of the load.
Static load and static load
When the relative speed of rotation of the bearing ring or gasket is zero (to the heart or thrust bearings) or when the rolling element movement in the rolling direction (linear bearing), the role of load on the bearings.
Dynamic load dynamic load
When the relative rotation of the bearing rings or gaskets (to the heart or thrust bearings) or when the rolling element in the rolling direction of movement (linear bearing), the role of the load on the bearing.
Equivalent load equivale nt load
Calculation of the theoretical load general terms, on specific occasions, bearing the load under the action of the theory as to withstand the actual load.
8 radial (axial) basic rated static load Basic static radial, (axial) the load rating
And the rolling element and raceway total amount of permanent deformation that corresponds to the radial static load (center axial static load). If the zero load, the roller and the roller (roller bearings) or assumed to the normal bus (all contacts), the maximum contact stress, the rolling element and raceway contact points generated by the total amount of permanent deformation of the rolling element 0.0001 times the diameter. Single row angular contact bearings, radial displacement of the radial component of the load caused by bearing rings are relatively pure radial load rating.
9 radial (axial) basic dynamic load basic dynamic radial (axial) load rating
Constan t radial center axial load (constant load), the load, Rolling theoretically can withstand 1 million to the basic rating life. Single row angular contact bearings, the radial load rating cause bearing rings are relatively pure radial displacement of the load weight.
10 life (means a set of bearings) life
Bearing a ring or a washer or a rolling element materials for the first time before the fatigue propagation, a ring or a washer relative to the number of revolutions of another ring or a washer. Life can also be used to represent the number of operating hours in a given constant speed.
11 reliability (refer to bearing life) reliability
Operate under the same conditions a group of nearly the same Rolling expect to meet or exceed the percentage of a specified life of the bearing. The reliability of a set of bearings that end bearing or the probability of exceeding the prescribed life.
12 rated life rating life
Radial basic rated dynamic load or axial basic dynamic load rating based on the life of predictive value.
13 basic rating life basic rating life
Reliability associated with 90% rated life.
14 The life expectancy coefficient life factor
Radial dynamic load or basic rated dynamic axial load, applies the equivalent dynamic load correction factor in order to get to the basic rating of the fixed set life.
15 pillow block bearing plummer block
A component of the radial bearings and seat combination with the base plate for mounting screws on the support surface parallel with the bearing axis line.
16 Vertical Block plummer block housing
Loaded Rolling Block.
17 flange seat flanged housing
Radial flange on the bearing axis line perpendicular to the bearing surface for the mounting screw holes of a seat.
18 adapte r sleeve adapter sleeve
Axial cylindrical bore opening sleeve, the outer surface of the cone and the small end of the external thread. Used to taper bearings installed (with lock nuts and lock washers) a cylindrical outer surface of the shaft.
19 Withdrawal sleeves withdrawal sleeve
Sleeve cylindrical hole axial openings, the outer surface of the conical external thread and the big end. Used to taper bearings in the cylindrical outer surface of the shaft installation or removal (with nut).
20 locknut locknut
A cylindrical outer surface and axial slot nut, washer outer claw and ring spanner nut. For Ball Bearing axial position.
21 lockwasher lockwasher
There are many outside claw the thin steel plate washer. An outer claw is used to lock nut, a claw insert the adapter sleeve or shaft axial slot.
22 eccentric sleeve eccentric locking collar
The relative in ternal hole eccentric groove rim at one end, install the elongation side of the outer spherical bearing inner ring of equal eccentricity. Relatively rotating inner eccentric sleeve to the inner ring fastening, and so tight - Top silk solid tight on the shaft.
23 concentric sets of concentric locking collar
Installed on the outer spherical bearings wide inner rim, and in contact with the shaft hole on the top wire screwed into the inner ring.
