The reducer is used as a power transmission organization; in the current organization for transmitting power and motion; the scale of the reducer is widely used. With the continuous development of technology; the demand for reducers in various occupations is constantly increasing. Corresponding; The demand for its components is also increasing; especially the need for high precision and rigidity is higher and more professional.
However, most of the current domestic speed reducers are low-end products; high-end reducers such as harmonic reducers, RV reducers and robots (300024) reducers are currently relying on imported brands; especially those robots that have emerged in these years and The world of aviation and the like seeks the limit of “lightweight”; liquid crystal and semiconductor manufacturing equipment are constrained by the height of the system production line; they are all looking for “ultra-thin” limits. The high-end reducers used in these professional circles also tend to be high-precision and small. Scale, combination and function are all; higher and more professional requirements are put forward for these high-end reducers.
High-precision interspersed roller bearings as the main bearing; show the superiority of other bearings can not be replaced; gradually replace other conventional bearings in high-end reducers; fine interspersed roller bearings are usually built on the output side of the reducer as the main bearing It is combined with the main body of the reducer as a whole; the volume is greatly reduced first; the applicable scale is expanded, and the built-in method of the finely inserted fine roller bearing with strong rigidity is adopted; the load can directly act on the output portion; Together; reduced the difficulty of the combination and the total cost.
High precision insert roller bearing use:
1. Machine tool: turret knife indexing, indexing plate, loader 2. Robot: Rotation, joint drive unit 3. Semiconductor manufacturing equipment: Transfer robots, view channels 4. Liquid crystal production equipment: transfer robot, viewing channel, sensitizer coating roller drive 5. Printing machine: sensitizer coating roller drive
