Spherical roller bearings with two rollers, mainly for radial load, but also can withstand any direction of the axial load, a high radial load capacity, especially for heavy duty or vibration load work, But can not afford pure axial load, aligning performance is good, to compensate for coaxial error. Mainly used for rolling machinery.
Spherical roller bearings common structural types:
(1) The basic type of self-aligning roller bearings 20000C type, asymmetric self-aligning sub-bearings for the 20000 type.
(2) tapered hole Spherical roller bearings 20000CK type (1:12) and 20000CK30 type (1:30), these bearings rely on the taper taper mounted on the cone axis, the use of axial bearing to adjust the amount of displacement to achieve and Axis with the amount of interference requirements, to avoid the large amount of interference due to the need to heat the installation of complex operation and easy to install is not easy to dismantle the problem, of course, increase the amount of interference will reduce the bearing radial clearance.
Standard cone conical hole Spherical roller bearings and adapter sleeve with the role of the structure, model 20000C + H000 type. H000 tight set of models, has been universal, standardized, with a variety of tapered bore bearings to match. This kind of structure bearing can be installed on the optical axis without the shoulder, which can meet the requirement of adjusting the interference amount, at the same time, it avoids the difficult problem of the conical shafts taper angle, which makes the bearing installation and disassembly more convenient.
Spherical roller bearing
As for the reason, it is considered that the lubricant is insufficient, not suitable for the defects of the oil discharge structure, the invasion of the foreign matter, the installation error of the bearing, the damage of the bearing of the roller bearing, Shaft deflection is too large, there will be these reasons overlap. Spherical roller bearing damage on the following focus on the performance of the form to do the following details.
1, cavitation
Spherical roller bearing cavitation is a solid surface in contact with the liquid and the relative movement of the surface damage generated by the form. When the oil in the low-pressure area of the oil film, the oil will form bubbles, bubbles move to the high-pressure zone, the bubble under pressure bubble collapse, the collapse of the moment have a great impact and high temperature, solid surface in this The repeated impact of the impact, the material fatigue occurs off, so that the friction surface of small pits, and then develop into a sponge-like scars. Heavy load, high speed, and the load and speed changes in the larger sliding bearings, often cavitation;
2, fluid erosion
Spherical roller bearing fluid erosion is the fluid violent impact on the solid surface will cause fluid erosion, so that the surface of the solid-like point-like scars, the damage surface is smooth;
3, electrical erosion
Spherical roller bearing electrical erosion is due to electrical or electrical leakage in the bearing friction between the surface of the spark generated in the friction surface on the point-like scars, which is characterized by reciprocating injury in the hard surface of the journal.
