Crb15013 Thin - Walled Cross - Roller Wheel Bearing

CRB15013Product technical parameters:

Product overview:
1. Structure RB15013 model thin-walled cross roller bearing is a kind of outer ring component, inner ring is integrated, the outer ring is divided into two pieces, and the inner ring is integrated, which is applicable to situations where high precision of inner ring rotation is required.
2. Life basic rated life refers to the total number of total specific revolutions that can be achieved when the same batch of bearing bearings produced by luoyang east shaft bearing operate separately under the same conditions, 90% of which can be achieved without surface peeling due to the fatigue of the rolling body. The following is provided by the technical department of luoyang east shaft bearing co., LTD to calculate the basic rated life of the bearing under fixed load: In terms of the number of rotations
P - equivalent dynamic load
Cr- basic rated load
The actual life of cross roller bearing is related to the structure, material, type selection, processing quality, bearing operating environment, peripheral structure design, installation and maintenance. Cross roller bearing the main form of failure is not a fatigue failure, because cross roller bearings with high rotation accuracy is usually composed of raceway and rolling body, wear the precision of the retainer is lost, the axial and radial clearance, or other abnormal damage of, at the same time, the bearing may not appear fatigue damage, so the calculation of basic rated life as a cross roller bearings service life only a reference.
3. Static load safety factor when the bearing is the radial, axial and overturning moment of the composite load function, the rolling element and raceway permanent deformation due to withstand the maximum load, if also can let a load equal to the amount of permanent deformation of the bearings, this imaginary load is the equivalent static load, its computation formula is as follows (the formula from luoyang east shaft bearing co., LTD. Technology) P0 = Fr + 0.444 + 2 m/Dpw Fa P0 - equivalent static load
Fr- radial load
Fa - axial load
M- minus - moment, N-mm
Dpw segment diameter = (d+ d) /2
4. Fs is mainly determined by the basic rated static load Co and the equivalent static load Po, fs =(Co/Po), where Co is the basic rated load; The reference of safety factor is as follows (according to different working conditions)
The wall thickness of the bearing pedestal of the bearing pedestal shall be designed according to over 60% of the normal section height. The wall thickness of the bearing pedestal T= (d-d) /2 * 0.6 above D is the outer diameter size of the outer ring; D is the inner diameter of the inner ring). If a threaded hole is set for the inner and outer ring removal, no damage will be caused to the bearing when the inner and outer rings are removed. Please avoid pushing the inner ring when removing the outer ring or pushing the outer ring when removing the inner ring.
6 lubrication cross roller bearing factory has note internal quality of lithium base grease, so the bearing can be used directly after the arrival of the goods, but it must be on a regular basis (about six months to one year) added the same type of grease, bearing grease injection, after the beginning of the friction torque can temporarily increase, such as excess oil spill after sealing ring, the torque value of the friction torque will soon return to normal.
7 related modelsLYDZ cross roller bearings are two columns of cylindrical rollers arranged vertically across each other through nylon isolation blocks on the 90-degree v-shaped raceway, so the cross roller bearings can withstand radial load, axial load and torque load. The inner and outer ring dimensions are miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity, the precision of LYDZ cross roller bearing can reach grade P2. Therefore, it is suitable for the joint rotating part of industrial robots, rotating table of machining center, precision rotating table, medical machine, calculator, IC manufacturing device and other equipment.
