The axial bearing profile editing
Axial bearing roller bearing thrust bearing of the kind, another kind is angular contact bearings.Axial bearing perpendicular to the axial installation, and can only carry axial force.Relative to the rolling bearing in the class of centripetal bearing radial bearing.Axial bearing has two kinds: one kind, is a ball bearing.Another kind is roller bearing.
The concept and classification of rolling bearings: editing
1, composition of the rolling bearing, in order to apply to the use of some special requirements, some parts of the some bearing can increase or decrease.With oil sealed bearing outer ring snap ring bearing outer ring bearing without inner ring bearing outer ring and without inner ring of the first chapter the general concept and classification of the rolling bearing
2, rolling bearing the function of the four items
Inner ring usually cooperate with shaft is tight, and together with the axis rotation.
Mixer outer ring is usually cooperate with bearing hole or mechanical parts of shell, supporting role.
Pieces with the help of roller cage homogeneous permutation, and between the outer ring, its practice, bearing capacity depends on the size and quantity directly.
In pieces cage will be evenly separated, roller guide roller in the right orbit.The first chapter is the general concept and classification of the rolling bearing
3, the type of roller ball (ball) spherical roller symmetry form spherical roller asymmetrical form and, in the shape of roll ChengZi load shaped charge big to small, shadow for cylindrical roller roller taper roller ring size?The first chapter the general concept and classification of the rolling bearing.
4, cage type black metal cage cage non-ferrous metal cage low carbon steel stainless steel bakelite plastic nylon 66 brass bronze alloy
Axial bearing and thrust bearing contact editor
Mainly used for rolling bearings under axial load, its nominal contact Angle is 45 ° ~ 90 °.Thrust bearing according to the different nominal contact Angle and divided into the following categories.
The concept of axial bearing
Axial bearing: nominal contact Angle is 90 ° of thrust bearing, such as thrust ball bearing, etc.
One-way thrust ball bearing ring and rolling body often is separable.One-way thrust ball bearings can only carry a one-way axial load.Two different ring of the inner hole diameter, diameter smaller is tight, it cooperate with shaft, the shaft rotation: larger inner diameter of the circle, with associated base solid, generally do not move.
Bidirectional thrust ball bearing can be subject to bi-directional load, middle ring ring, cooperate with shaft, the other two circles as loose circle .
The concept of thrust angular contact bearings
Thrust angular contact bearings: nominal contact Angle is 45 ° ~ 90 ° of thrust bearing, such as thrust angular contact bearings, etc.
One-way thrust angular contact ball bearings can withstand a direction axial load, two-way thrust angular contact ball bearing characteristics can be subject to both radial and axial load of the joint load.
The main characteristics of bearing editor
The characteristics of the sliding bearing
Sliding bearing is mainly has high bearing capacity, stable and reliable, low noise, small radial size, high precision, less fluid lubrication friction and wear, the oil film has certain advantages of vibration absorbing ability.Of course, for the liquid friction sliding bearing, the friction is bigger, badly worn.For liquid friction sliding bearings at startup, driving, load, speed is bigger it is difficult to achieve liquid friction;Liquid friction sliding bearing design, manufacturing, maintenance cost is high.
The characteristics of the rolling bearing
Compared with sliding bearing, roller bearing of the main advantages as follows:
1) the smaller friction torque and fever.In normal range of speed, friction torque rarely change with speed.Starting torque is much lower than sliding bearing (80% - 90% smaller than the latter).
2) maintenance more convenient, lubricant consumption is small.
3) the bearing capacity of the bearing unit width is bigger.
4) greatly reduce the consumption of non-ferrous metal.
Rolling bearing fault is: outside the radial profile size is larger than sliding bearing: contact stress is high, poor ability to withstand the shock load, high speed low under heavy load life: small batch production of special high cost when rolling bearing;Vibration reduction ability is lower than sliding bearing.
