XR/JXR series for cross research on the development of tapered roller bearings has the ability to compare two sets of raceways and rollers, which are combined at right angles to each other, and the staggered rollers have opposite effects. The height of the cross-section of the bearing is very close to that of the single-row bearing, so the space and the material of the bearing seat are saved. The overall bearing system uses a large cone angle and a tapered design to increase the effective span of the bearing enterprise's own development width. several times. Cross tapered rollers can withstand high overturning moment and are suitable for machine tools, including vertical boring, grinding machine table, machine tool precision circular indexing table, large hobbing machine, turntable, industrial robot, etc.
Design and structural features of crossed tapered roller bearings
1. The line contact on the raceway and the roller structure provides the bearing with greater rotational motion accuracy, high stability and greater rigidity of the tilting structure.
2. The adjustable design of the preload prolongs the life of the bearing, greatly improves the rigidity, and provides a small runout.
3. The nylon spacer has a lower inertial mass, which has little effect on the running torque.
4. High rotation precision, good rigidity, saving material cost.
Features of crossed tapered roller bearings
1. The main purpose of high-precision crossed tapered roller bearings is to meet the high-precision rotation requirements under axial, radial and multi-directional loads. The bearing consists of an outer ring, split inner ring and tapered rollers arranged crosswise. The rollers are separated by nylon spacers. The X-arranged tapered rollers in the bearing raceway can well bear axial and radial loads and tilting moments, so that the bearing can maintain as high rigidity as possible in the smallest possible cross-section, and a single bearing can realize the traditional combination Alternatives to bearing design.
2. The tapered rollers can effectively prevent one-way sliding between the rollers and the raceway, so as to achieve a longer service life of the bearing. The lubrication of the bearing is carried out through the gap between the inner rings, which is simple and convenient.
3. The finished product of the bearing is not assembled, and the user can calibrate and preload it when using it. The preload can be adjusted to a large extent to ensure the rigidity of the bearing and ensure high rotation accuracy. BYC Boying bearing adopts high-quality bearing steel and special heat treatment process to ensure the quality and life of the bearing, which can meet the design requirements of precision rotary equipment such as CNC vertical lathe. The bearing itself has a lifting hole, which is easy to install and use.
