Track Roller Bearings Mainly bear
Casing 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 elements in the bearing into a single row, double row and four rows of track roller bearings. Single row of track roller bearing clearance to be installed at the time of adjustment; double row and four rows of track roller bearing clearance has been shipped in the product according to user requirements given, without user adjustments.
The track roller bearings have conical inner and outer raceways, and tapered rollers are arranged between the two. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes track 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.
The track roller bearing is usually of the split type, i.e. the conical inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the conical outer ring (outer ring).
Crawler roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
The secondary cause of the occurrence of the track roller bearing in the process is that the bearing is being installed, 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 to install the track roller bearings in accordance with the work norms to stop, or will form a lot of results, 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, the number of life and function.
Track roller bearing quality and other aspects are better, but the rolling bearing is a precision component, its use must also be carefully carried out accordingly. No matter how high the performance of the bearings, if used improperly, will not get the expected high performance. The following concerns apply to the bearing:
(1), keep the track roller bearing and its surroundings clean.
Even if the eyes can not see the small dust, will give the bearing a bad influence. Therefore, to keep the surrounding clean, so that dust will not penetrate the bearing.
