Product introduction Product Information
Product Category: High Precision Cross Roller Turntable Bearing Brand: Luoyang East Axis Bearing Type: Cylindrical Roller Bearing Material: Bearing Steel Special Purpose: High Precision Mechanical Equipment is customized: Processing Origin/Manufacturer: Luoyang Product Real Shooting Picture Front The inner and outer rings of this series of models are integrated structures, which are used for the rotation of the outer and inner rings. Structural features: The cross roller bearing is characterized in that cylindrical rollers are vertically arranged on the rolling surface of a 900 V-shaped groove through isolation blocks, so the cross roller bearing can bear multi-directional loads such as radial load, axial load and moment load.
The size of inner and outer rings is miniaturized, and the ultra-thin form is close to the limit of small scale and has high rigidity, and the accuracy can reach P5, P4 and P2 levels. Therefore, it is suitable for joints and rotating parts of industrial robots, rotating tables of machining centers, precision rotating tables, medical machines, calculators, military industries, IC manufacturing devices and other equipment. Rotational accuracy: spacers are installed between the vertically arranged rollers in the bearing, which prevents the inclination of the rollers and the friction between the rollers, and reduces the rotational torque. In addition, compared with the previous use of steel plates to hold the skeleton, there is no contact phenomenon or locking phenomenon of the roller on one side.
At the same time, because the inner ring or outer ring) is divided into two parts, the bearing clearance can be adjusted, and even if preload is applied, the high-precision rotary motion can be obtained. After the rollers and spacer are installed, they are fixed together with the cross roller collar. Usage characteristics: The divided inner ring (or outer ring) prevents the angle of separation from each other, so it is easy to operate when installing the cross roller collar. The spacer can eliminate the mutual friction between the rollers and prevent the rollers from getting nitrogen, thus obtaining stable rotary torque. Because the rollers are crossed, only one set of crossed roller bearings can bear the loads in all directions.
Compared with the traditional model, the rigidity is improved by 3- 4 letters. The four-point contact ball turntable bearing on the back is one of the widely used parts, and almost all the bearing manufacturers have dealt with it. Most colleagues think that turntable bearings are very difficult "opponents", which are easy to crack in water quenching and hard in oil quenching. The bearing is mainly used for assembling various mechanical equipment, and the large bearing can be used in a rotating state, and the positioning direction of the machinery can also be changed; Small bearings are basically quenched and tempered. According to requirements, bearings can also be tempered at low or medium temperature after quenching.
With the development of national economy and the demand of export-oriented economy, 010.40.800 bearing can be used not only to manufacture various components in engineering, but also to manufacture low-grade optional parts, as well as slow cutting wire equipment, pig raising equipment, and also to assemble various hardware tools such as various machines, as well as various garden machinery and agricultural machinery tools.
The following is a brief introduction to the production technology and surface modification of turntable bearings for reference by colleagues in the industry. The general heat treatment process of the bottom four-point contact ball turntable bearing is as follows: 1) Blank softening treatment: 740~760ºC×4~6h, furnace cooling to 600ºC at a cooling rate of 50~100ºC/h, and air cooling. 2) Normalization: heating at 850~870ºC, discharging and air cooling. 3) Quenching and tempering: quenching at 840~860ºC and tempering at 450~550ºC. 4) Quenching+tempering: heat quenching at 820~840ºC, and select appropriate coolant according to the actual situation; Tempering process depends on the required mechanical properties of the workpiece.

The critical quenching diameter is 10~15mm when running water is cooled and no more than 25mm when salt water is cooled. If the size of the workpiece exceeds the critical quenching diameter, the quenching and tempering effect will be poor, and the bigger the size, the worse the effect will be. Therefore, the quenching and tempering treatment of 45 steel large cross-section workpiece will not get uniform structure along the cross-section, and can not achieve the quenching and tempering effect. In order to improve this situation, it is generally adopted to raise the heating temperature or select severe cooling medium, the former will cause oxidation and decarburization, and the latter will easily cause deformation and cracking. Therefore, normalizing is often used as the final treatment for workpieces quenched beyond the critical diameter. However, besides the slow cooling speed, the cooling speed is also affected by environment, air temperature and temperature. Customization shows that the hardness of Custom instructions cannot be controlled and the quality of normalizing is difficult to guarantee.
Some people in China have studied the heat treatment process of quenching with boiling water instead of quenching and tempering, which has achieved success. Now it is briefly introduced as follows: wC of 45 steel used for test is 0.46%, heated in a box furnace, the sample specifications are φ50mm×150mm, φ70mm×210mm, φ80mm×210mm, the heating temperature is 840ºC, and it is cooled by boiling water at 100ºC.
