As we all know; the overall nature of high-precision processing equipment and industrial workers in China is still far from the foreign countries; this is why the YRT turntable bearings produced in China have always been unstable; it is difficult to satisfy the needs of users; The YRP turntable bearing rejection rate is high; the production cost is greatly increased; the production cycle is too long; and it is difficult to form a batch production; and the interspersed roller bearing just makes up for the shortcomings of YRT rotary table bearings in these aspects; the layout is relatively simple; production and processing The process is simple; the demand for production equipment is low; relatively simple to reach higher precision; and can quickly form mass production capacity; the production cycle is relatively short; the cost is significantly reduced in relation to YRT turntable bearings.
There are many similarities in the function and application of the interspersed roller bearing and the YRT rotary table bearing. The utility model has the functions of high rigidity, high precision, high bearing capacity and high rotation speed. It is widely used in application and high precision. CNC indexing plate, vertical machining intermediate, vertical grinder and other equipment; there is no big difference between the insert roller bearing and the YRT rotary table bearing in function and application.
However, the interspersed roller bearing has the advantage of not exceeding the YRT rotary table bearing in other aspects; firstly; the interspersed roller bearing and the YRT rotary table bearing in the same scale segment; the interspersed roller bearing layout is relatively simple; after a row Cylindrical tumbling bodies placed on each other on a single raceway; considerable axial, radial bearing capacity and overturning moment can be obtained; and YRT turret bearings need to be sequentially placed on three rows of raceways through three rows of cylindrical tumbling bodies. Release; the ability to achieve the same effect; this brings great inconvenience in the production and processing; related to the single-row raceway with the inserted roller bearing; YRT rotary table bearing production processing complexity is greatly added; the difficulty is also greatly improved This puts high demands on the nature of production and processing equipment and production personnel.
As far as the operator is concerned, the cost performance of the interspersed roller bearing is much higher than that of the YRT rotary table bearing; this is the main reason why the interdigitated roller bearing gradually replaces the YRT rotary table bearing in these years; it can be imagined; in the near future; high precision Inserting roller bearings will replace YRT rotary table bearings in a wide range.
