Abstract
The utility model relates to a meshing mechanism and particularly relates to a hollow shaft meshing mechanism for a speed reducer of heavy machinery. The hollow shaft meshing mechanism comprises a box body in which a gear shaft is arranged and a hollow shaft is inserted; the lower end of the gear shaft is sleeved with a toothed sleeve; the hollow shaft is sleeved with a gear; the gear is meshed with the toothed sleeve; two ends of the gear shaft are fixed to the box body through a single row of roller bearing; and the hollow shaft is fixed to the box body through double rows of roller bearings; and a spacer ring is arranged between the double rows of the roller bearings. The hollow shaft meshing mechanism for the speed reducer of the heavy machinery is simple in structure and excellent in use effect.
Description
Technical field
The utility model is a kind of engaging mechanism, particularly a kind of hollow shaft engaging mechanism that is used for the heavy machinery retarder.
