Abstract

The invention discloses a waterproof rotary driving device. The device comprises a base, a rotary support and a worm and is provided with a top plate, wherein the worm is arranged in a shaft shell of the base; the rotary support comprises an inner ring, an outer gear ring and a ball which is embedded between the inner ring and the outer gear ring; the inner ring is fixed above a seat ring of the base; the outer gear ring is engaged with the worm; the top plate is arranged above the outer gear ring and the inner ring; a lip-type sealing ring is arranged between the outer gear ring and the seatring; a plurality of blind holes which are formed downwards are formed in the inner ring; an annular bulge is arranged below the top plate; the inner side and the outer side of the annular bulge are provided with an O-shaped sealing ring respectively; an annular step is arranged on the seat ring; one end face of the lip-type sealing ring is arranged on the annular step; and the top plate and the outer gear ring as well as the inner ring and the seat ring are connected through bolts and waterproof gaskets. In the invention, the problem of water inflow of three key parts into which water extremely easily flows in the rotary driving device is solved, and the waterproof grade of the device can reach more than IPX6.

Description

technical field [0001] The invention relates to a rotary drive device, in particular to a waterproof rotary drive device. Background technique [0002] The slewing drive device is a device widely used in engineering machinery, construction machinery, solar photovoltaic and other industries. Usually, the slewing drive device needs to operate in the natural environment and harsh environmental conditions, especially in the tropical rainforest and other areas, and it is often operated under heavy rainy weather conditions. The service life of the device is greatly reduced. Therefore, higher and higher requirements are put forward for its sealing and waterproof performance. The usual method is to add a rain cover to the slewing drive, or to adopt a conventional sealing and waterproof structure, but the sealing and waterproof effects are not ideal, and the scope of use of the slewing drive is limited. Contents of the invention [0003] The inventor found through research that ...
