Taper Roller Bearings Are Mainly Subjected To Radial-based Radial And Axial Combined Loads
Taper Roller Bearings are mainly subjected to radial-based radial and axial combined loads. Bearing bearing capacity depends on the outer raceway angle, the greater the angle the greater the carrying capacity. This type of bearing is a separate bearing, according to the number of rolling bearings in the bearing is divided into single row, double row and four row Taper Roller Bearings. Single row tapered roller bearing clearance to be installed at the time of adjustment; double row and four row of tapered roller bearing clearance has been in the product factory according to user requirements given, no user to adjust.
Taper Roller Bearings have conical inner and outer ring raceways, tapered roller arrangement between the two. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes Taper Roller Bearings particularly suitable for receiving composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The angle size is expressed by the calculation factor e; the greater the e value, the greater the contact angle, the greater the applicability of the bearing to the axial load.
Taper Roller Bearings are usually separable, that is, by the roller with the cage assembly of the inner ring of the conical inner ring assembly can be installed with the conical outer ring (outer ring).
Taper Roller Bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
The secondary reason that the tapered roller bearing is emerging in the process is that the bearing is being mounted, the inner ring is formed during assembly, and the outer ring is skewed; or is the current charge in the process of assembly and assembly, and the final formation of the bearing The
Is the installation of Taper Roller Bearings in accordance with the work norms to stop, or will form a lot of achievements, such as the form of the device or the way is not, then the formation of the bearing raceway surface and the formation of bearings on the backbone of the emergence of linear marks. Deep groove ball bearing device indirectly reflects the use of bearings when the precision, life and function.
Tapered roller bearing quality and other aspects are better, but the rolling bearing is a precision component, its use must also be carefully accordingly. No matter how high the performance of the bearings, if used properly, will not get the expected high performance. The following concerns apply to the bearing:
(1) Keep the tapered roller bearing and its surroundings clean.
Even if the eyes can not see the small dust, but also to bring a bad bearing impact. Therefore, to keep the surrounding clean, so that dust will not penetrate the bearing.
(2) be careful to use.
In the use of Taper Roller Bearings to give a strong impact, will produce scars and indentation, as the cause of the accident. Severe cases, will crack, break, so must pay attention.
(3) use the appropriate operating tools.
Avoid using existing tools instead, and you must use the right tools.
(4) should pay attention to the corrosion of Taper Roller Bearings.
Operation of the bearing, the hands of the sweat will become the cause of rust. Pay attention to the use of clean hands, it is best to bring gloves as much as possible.
Taper Roller Bearings use auditory to identify irregular operation is a very common method, such as the use of electronic stethoscope to detect a part of the abnormal noise is experienced operators to use. If the bearing is in good operating condition will be issued a low whining sound, if issued a sharp hissing Taper Roller Bearings, squeak and other irregular sound, usually that the bearing in a bad operation.
1, tile surface corrosion: spectral analysis found that non-ferrous metal element concentration anomalies; iron spectrum in the emergence of many non-ferrous metal components of sub-micron wear particles; lubricants moisture exceeded, acid value exceeded.
2, journal surface tension: iron in the iron cutting grain or black oxide particles, the presence of metal surface tempering color.
