Detailed Description
The embodiment is a slewing mechanism of a slewing crane suitable for a gantry hoist, and the slewing mechanism is provided with a slewing bearing, a pinion and a slewing driving mechanism.
In the embodiment, the inner ring of the slewing bearing is connected with a slewing platform needing to slew by a bolt, the outer ring of the slewing bearing is connected with a support through a bolt, a circle of large gear ring is coaxially sleeved on the periphery of the slewing bearing and fixedly connected with the support through a bolt, namely the large gear ring is fixedly connected with the periphery of the slewing bearing through the support.
In this embodiment, the pinion gear is engaged with the bull gear, and the pinion gear is mounted on a rotary drive mechanism that is fixed to the rotary platform. The rotary driving mechanism drives the small gear to rotate, and the small gear is meshed with the large gear ring on the support, so that the rotary platform is driven to rotate around the rotary support.
In the embodiment, the large gear ring is provided with a gear ring, a plurality of teeth matched with the small gear are uniformly arranged on the outer side surface of the gear ring, an annular connecting plate is arranged on the inner side surface of the gear ring, a plurality of mounting holes are uniformly formed in the connecting plate, and the gear ring is connected with the connecting plate through a plurality of reinforcing plates. In this example, the large gear ring is placed on the support and fixed on the support through bolts in the mounting holes.
For the installation, the system has the mounting groove with slewing bearing's outer lane looks adaptation on the support to and the mounting groove with bull gear looks adaptation.
The system has the round go-between on the lateral surface of slewing bearing inner circle in this embodiment, the system has the round mounting groove on the medial surface of slewing bearing outer lane (the outer lane comprises upper and lower two parts, the mounting groove is formed after two parts splice from top to bottom), the mounting groove of slewing bearing outer lane is arranged in to the go-between of slewing bearing inner circle to be equipped with rolling element I, II respectively on the go-between, down and between the mounting groove, the outside that corresponds the go-between on the mounting groove lateral wall is equipped with rolling element III.
