The role of SKF bearing axial clearance
Fix one ferrule, and the maximum amount of movement of the other ferrule in the radial or axial direction. The maximum amount of movement in the radial direction is called radial clearance, and the maximum amount of movement in the axial direction is called axial clearance.
Generally speaking, the larger the radial clearance, the larger the axial clearance, and vice versa. According to the state of the bearing, the clearance can be divided into the following three types:
Original clearance
The clearance in the free state before the SKF bearing is installed. The original clearance is determined by the processing and assembly of the manufacturer.
Installation clearance
Also called the fit clearance, it is the clearance when the bearing and the shaft and the bearing seat are installed but not yet working. Due to the interference installation, the inner ring is enlarged, or the outer ring is reduced, or both, the installation clearance is smaller than the original clearance.
Working clearance
The clearance of SKF bearing in the working state, the maximum temperature rise of the inner ring and the largest thermal expansion during operation, so that the bearing clearance is reduced
SKF bearing clearance; at the same time, due to the load, the contact between the rolling elements and the raceway produces elastic deformation, which increases the bearing clearance. Whether the working clearance of the bearing is larger or smaller than the installation clearance depends on the combined effect of these two factors.
SKF deep groove ball bearing
The most representative rolling bearing with a wide range of applications
Can bear radial load and bidirectional axial load
< P>Suitable for high-speed rotation and occasions requiring low noise and low vibrationSealed bearings with steel dust caps or rubber seals are pre-filled with a proper amount of grease
Bearings with a snap ring or flange on the outer ring are easy to locate in the axial direction and facilitate installation in the housing
The size of the maximum load bearing is the same as the standard bearing, but there is a filling in the inner and outer rings Groove, increase the number of balls and increase the rated load
Mainly applicable cage: steel stamping cage (wave, crown shape...single row; S shape...double row)
Copper alloy or phenolic resin cutting cage, synthetic resin molding cage
Main use: Automobile: rear wheel, transmission, electrical device components
Electrical : General electric motors, household appliances
Others: meters, internal combustion engines, construction machinery, railway vehicles, handling machinery, agricultural machinery, various industrial machinery
SKF angular contact ball bearings
There is a contact angle between the ring and the ball. The standard contact angles are 15°, 30° and 40°
The larger the contact angle, the axial load capacity Also larger
The smaller the contact angle, the more conducive to high-speed rotation
Single row bearings can bear radial load and unidirectional axial load
DB combination, DF combination and double row bearings can bear radial load and two-way axial load
DT combination is suitable for applications where one-way axial load is large and the rated load of a single bearing is insufficient
High speed ACH type bearings have small ball diameters and a large number of balls. Most of them are used in machine tool spindles.
Angular contact ball bearings are suitable for high-speed and high-precision rotation
The structure is a combination of two on the back Single row angular contact ball bearings share the inner ring and outer ring, which can withstand radial load and bidirectional axial load
Bearings without filling grooves are also sealed
Mainly applicable cages: steel stamping cages (bowl shape...single row; S shape, crown shape...double row)
Copper alloy or phenolic resin cutting cage, synthetic resin forming cage
Main purpose: Single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, front wheel of small car, differential pinion shaft
Double row: oil pump, Roots blower, Air compressors, various transmissions, fuel injection pumps, printing machinery
SKF four-point contact ball bearings
Can bear radial load and bidirectional axial Load
A single bearing can replace the angular contact ball bearing with front or back combination
Suitable for bearing pure axial load or synthetic load with large axial load component
This type of bearing can be formed when bearing axial load in any direction A contact angle (α), so the ferrule and the ball are always in contact with three points on both sides on any contact line
Main applicable cage: copper alloy cut cage
Main Application: Aircraft jet engine, gas turbine
SKF solid needle roller bearing
The basic structure of inner ring bearing and NU type cylindrical roller bearing The same, but due to the use of needle rollers, the volume can be reduced and can withstand large radial loads. Bearings without inner ring should use the mounting surface of the shaft with appropriate accuracy and hardness as the raceway surface
Cage: steel stamping cage
Main use: automobile engine, transmission, pump, excavator crawler wheel, hoist, bridge crane, compressor
SKF tapered roller bearings
This type of bearing is equipped with truncated cone-shaped rollers, which are guided by large inner ring ribs.
The design makes the inner ring raceway surface, The apex of each conical surface of the outer ring raceway surface and the roller rolling surface intersects at a point on the bearing centerline
Single row bearings can bear radial load and unidirectional axial load, double row bearings can bear Radial load and bidirectional axial load
Suitable for bearing heavy load and impact load
According to the difference of the contact chest (α), it can be divided into small cone angle, medium cone angle and large cone angle. Three types of taper angle, the larger the contact angle, the greater the axial load capacity
The outer ring and inner components (inner ring and roller and cage components) can be separated for easy assembly and disassembly
The bearings with the rear auxiliary code'J' or'JR' are internationally interchangeable
