Cylindrical Roller Bearings
Moving body is cylindrical roller Rolling to the heart. Cylindrical Roller Bearings The internal structure of the roller was 90 ° aligned perpendicularly intersecting each other (this is the crossed roller bearings origin of the name), equipped with a space between the roller cage or spacers can be prevented inclined roller or rollers grinding police each other, effectively preventing the increase of rotational torque.
26. Cylindrical roller bearings deep groove ball bearings with the same point:
The main radial load mainly, can withstand a small part of the axial load.
Cylindrical roller bearings and deep groove ball bearing with different:
1, the use of deep groove ball bearing high speed limit, the axial load carrying capacity is relatively large, the radial load carrying capacity is relatively small;
2, cylindrical roller bearings deep groove ball bearings speed limit not high, basically can not bear axial load, but the radial load carrying capacity is relatively large.
Cylindrical roller bearings and deep groove ball bearing selection based on:
At low speed and heavy case of the preferred cylindrical roller bearings, high-speed light-load conditions preferably deep groove ball bearings. Speed limit and rated load bearing concrete To see Mechanical Design Handbook or consult the manufacturer.
Aligning bearings for heavy loads, poor working conditions or sealed bearing arrangement special requirements, you can use the built-in contact-type seal self-aligning roller bearings; these bearings especially suitable for heavy work loads or vibration loads, spherical roller in between the two bearings have raceways in the inner and outer ring raceway is spherical, the assembly of a drum-shaped roller bearings.
Spherical roller bearings accuracy sorting size is directly related to the level of efficiency of combined units, newly opened bearing staff believe in separation process makes sorting size major sources of error are as follows:
1, operator skill level of influence. As the size of the force measurement products, the reading accuracy of the instrument malfunction judgment and adjustment of skills to the table.
2, the measured ring geometry tolerances influence.
3, measurement, temperature change.
4, when measured separation between the environment, the impact on the measurement of illuminance readings, impact rings and equipment cleaning degree from assembly operations affected by external vibration and the like.
5, stability, and the pivot point of the instrument and the measuring instrument a value indicating the accuracy of the degree of wear, the uniformity of the load.
6, sense of responsibility. Axial spherical roller bearings. Establish whether the idea of quality first, whether the work of emotional and mental concentration will affect the case of sorting size untrue, causing chaos ring size.
7, roller size standard error values and the degree of wear itself, the calculated error and dimensional stability.
