The utility model solves the problems by adopting the following technical scheme: the utility model provides a slewer with oil baffle, it includes the base, the base includes seat circle and axle housing, be provided with slewing bearing on the seat circle, slewing bearing includes inner circle and outer ring gear, be provided with a plurality of balls between inner circle and the outer ring gear, the axle housing is provided with the flange in slewing bearing corresponds one side, the axle housing includes worm wheel chamber and worm chamber, be provided with the pivot between worm wheel chamber and the flange, be provided with worm wheel and gear in the pivot, the worm wheel sets up in the worm wheel intracavity, the worm intracavity is provided with the worm, the worm wheel meshes with the worm, the gear meshes with outer ring gear, be provided with the oil baffle between axle housing and the flange.
Optionally, the race and the axle housing are arranged up and down, and the worm cavity is located below the worm gear cavity.
Optionally, the inner ring is connected with the seat ring through bolts.
Optionally, the flange is connected with the axle housing by bolts.
Optionally, the oil baffle is connected with the flange through a screw.
Optionally, the worm wheel is provided with the oil blanket in the oil baffle plate corresponding one side.
Optionally, the oil seal is located in an inner area of the oil baffle, and a lip of the oil seal is pressed on the oil baffle.
Optionally, a sealing ring is arranged between the installation surfaces of the worm wheel and the gear.
Compared with the prior art, the utility model has the advantages that:
according to the rotary device with the oil baffle, the oil baffle and the sealing assembly separate the shaft housing from the external environment to form an independent space, so that on one hand, grease in the worm cavity is effectively prevented from flowing out, on the other hand, impurities are prevented from entering, and the service life of the device is greatly prolonged.
