In the processing of bearing parts, a large number of special bearing equipment are used. Rolling Bearing Process For example, ball grinding machine, grinder and other equipment are used for steel ball processing. The characteristics of specialization are also reflected in the production of bearing parts, such as steel ball companies specializing in the production of steel balls, micro bearing factories specializing in the production of micro bearings, etc.
The specialization of bearing production provides conditions for its production automation. Rolling Bearing Process Full automatic, semi-automatic special and non special machine tools are widely used in production, and automatic production lines are gradually popularized and applied. Such as automatic heat treatment line and automatic assembly line.
3. advanced nature
Due to the large-scale requirements of bearing production, it is possible to use advanced machine tools, tooling and technology. Rolling Bearing Process Such as CNC machine tools, three jaw floating chuck and protective atmosphere heat treatment.
namely radial thrust ball bearing, can be loaded with more steel balls, its radial bearing capacity is greater than that of ordinary ball bearing, and can also bear large axial load or pure axial load at the same time. Rolling Bearing Process Its allowable working speed is similar to that of deep groove ball bearing and its support rigidity is stronger, but it requires accurate installation and is very sensitive to axis misalignment error,
Generally, it does not need to bear the radial load alone, but it must bring additional axial load while bearing the radial load. This kind of bearing has many variants and is widely used. Rolling Bearing Process It is often made into three series with 15 °, 25 ° and 40 ° contact angles. The larger the contact angle is, the higher its axial load capacity is. However, it is appropriate to use a small contact angle at high speed.
Most of these bearings are used in pairs for small-span rigid double support shafts or precision spindles. Rolling Bearing Process When in use, the clearance should be carefully adjusted. By changing the axial distance between the inner and outer rings of the bearing, the internal clearance of the bearing can be adjusted.
At the same time, several sets of bearings can be installed in parallel and given a certain pre interference, Rolling Bearing Process which can improve the rigidity of the bearing system.
can only bear the axial load in one direction. Rolling Bearing Process At the same time, other bearings need to be configured to offset their additional axial forces. When installed in pairs, their additional axial forces offset each other, and they can bear the axial load of two forces upward, and have strong axial limit capacity in two directions,
Generally, two sets of bearings are installed in pairs, with their outer ring wide end face opposite (back-to-back) or narrow end face opposite (face-to-face), in which the rigidity of the back-to-back installation Rolling Bearing Process bearing system. In order to facilitate installation in pairs or groups, some bearing factories supply bearings in pairs, three sets in groups and four sets in groups.
In this way, the processing consistency of the supplied bearings in the same batch is good, the load is borne more evenly during use, and the additional axial forces Rolling Bearing Process offset each other more thoroughly.
This type of bearing can be divided into two types: separated type and non separable type. The separated type bearing is used when the installation conditions are limited and the outer ring Rolling Bearing Process or inner ring is required to be removed from the whole set of bearings for separate installation.
Because the separated type angular contact ball bearing is widely used in magneto, it is also called magneto bearing. Rolling Bearing Process In this type of bearing, the locking port is on the inner ring, which can be adapted to higher speed.
