Structure and performance characteristics of fag bearing

Thrust angular contact ball bearing of characteristics of fag bearing

The contact angle of thrust angular contact ball bearing is generally 60 °. The commonly used thrust angular contact ball bearing is generally a two-way thrust angular contact ball bearing, which is mainly used for the spindle of precision machine tools. It is generally used together with double row cylindrical roller bearings, and can bear two-way axial load. It has the advantages of high precision, good rigidity, low temperature rise, high speed, convenient assembly and disassembly, etc.

Deep groove ball bearing of characteristics of fag bearing

Structurally, each ring of deep groove ball bearings has a continuous groove raceway with a cross-section of about one-third of the circumference of the equatorial circle of the ball. Deep groove ball bearings are mainly used to bear radial loads, but also can bear certain axial loads. When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load alternating in two directions.
Compared with other types of bearings with the same size, this type of bearing has small friction coefficient, high limit speed and high precision. It is the preferred bearing type for users to select. Deep groove ball bearing has simple structure and convenient use. It is a kind of fag bearing with large production volume and wide application range.

Thrust tapered roller bearings of characteristics of fag bearing

Because the rolling element in the thrust tapered roller bearing is a tapered roller, the rolling bus and the raceway bus of the washer meet at a point on the axis line of the bearing in structure, so the rolling surface can form pure rolling, and the limit speed is higher than the thrust cylindrical roller bearing. Features: thrust tapered roller bearing can bear one-way axial load. The type code of thrust tapered roller bearing is 90000.

Structure and performance characteristics of double row tapered roller bearings of characteristics of fag bearing

There are many structures of double row tapered roller bearings, a large number of which are 35000 type. There is a double raceway outer ring and two inner rings. There is a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer. This kind of bearing can bear both radial load and bidirectional axial load, which can limit the axial displacement of the shaft and housing within the range of axial clearance of the of characteristics of fag bearing.
Structural of characteristics of fag bearing tapered roller bearings. The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate bearing. Tapered roller bearings are mainly used to bear the combined radial and axial loads dominated by radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or housing in one direction.

Working principle of the new wheel hub of characteristics of fag bearing

When the vehicle is at low and medium speed, the wheel speed can be detected with 40 times the original accuracy by using high-resolution signals. Only 1mm movement of the standard vehicle can be detected, and the braking force can be controlled at the right time when controlling the vehicle. In the high-speed situation where ABS control is the main purpose, low resolution signals are used to reduce the burden of data processing.
The high-resolution signal of the developed product outputs two kinds of pulses,phase A and phase B. by observing the output of these pulses, we can detect whether the vehicle is moving forward or backward. This can be used to detect whether the car slips and stops automatically when starting on a ramp.
The wheel speed sensor uses the sensor (fixed side) to detect the magnetic pole change of the magnetic encoder (rotating side) that magnetizes the N pole and S pole alternately at the same interval in the circumferential direction, which is used as the wheel rotation signal for vehicle control, etc. Reducing the rotation signal, that is, improving the resolution, can control the vehicle more finely.

using the original magnetic encoder with SNR, we developed a magnetic sensor with a high resolution of 40 times the original, and embedded the magnetic sensor to develop “hub fag bearing with high resolution rotation sensor” in 2007. Because the burden of data processing increases when the resolution is high and the speed is high, the function of switching the resolution is added.
Due to the built-in rotation sensor of the new wheel hub fag bearing, which can switch the signal resolution in two levels, it will be more convenient to detect the vehicle speed and control ABS.
