Description

Slewing bearing sealing device of mining truck

Technical Field

The utility model belongs to mining machinery equipment field, specifically speaking relates to a slewing bearing sealing device of mining truck.

Background

At present, because the mine environment is severe, a mining truck adopting a slewing bearing often runs in muddy water, the sealing of the common slewing bearing cannot prevent fine sand in the muddy water from entering the inner raceway of the slewing bearing through sealing, and the sand entering the inner raceway of the slewing bearing rolls along with the inner balls to abrade the raceway of the slewing bearing, so that the inner ring and the outer ring of the slewing bearing are separated from the inner raceway, and the service life of equipment is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a slewing bearing sealing device of mining truck has solved slewing bearing sealing device among the background art and has sealed not tight, influence equipment life's shortcoming.

The technical scheme of the utility model is realized like this: a slewing bearing sealing device of a mining truck comprises an inner ring and an outer ring of a slewing bearing, wherein a slewing bearing raceway is arranged between the inner ring and the outer ring, an inner ring groove and an outer ring groove are respectively arranged at two ends of the inner ring and the outer ring, lip seals are arranged in the inner ring groove and the outer ring groove, the bottom end face of a lip of one end of the lip seal is contacted with the end face of the outer ring groove, the end faces of an upper lip and a lower lip of the lip seal are contacted with the end face of the inner ring groove, the end faces of the upper lip and the lower lip of the lip seal at the other ends of the inner ring and the outer ring are contacted with the end face of the outer ring groove, and the bottom end face of the lip seal is contacted with the end face of the inner ring groove; the upper lip and the lower lip seal two ports of the slewing bearing raceway; the pressure plate is fixed on the inner ring or the outer ring through bolts in the threaded holes, and the pressure plate is used for fixing the lip seal in the inner ring groove and the outer ring groove.

The utility model has the advantages that: the utility model discloses installation lip seal and clamp plate between slewing bearing inner and outer lane, the lip seal compresses tightly the back at the clamp plate, the tight slewing bearing's of subsides that can be inseparable inner and outer lane, even slewing bearing moves in muddy water for a long time, also can effectively stop tiny grit etc. and enter into the inside raceway of slewing bearing, makes the ball good operation under the effect of the inside lubricating grease of slewing bearing all the time, extension slewing bearing's life.
