Summary of the invention
The technical problem to be solved in the present invention is: for the problem of above-mentioned existence, provide a kind of simple in structure, easy for installation and can effectively solve the Pallet truck auxiliary wheel revolution supporting mechanism of the dustproof problem of bearing lubrication.
The technical solution adopted in the present invention is: a kind of Pallet truck auxiliary wheel revolution supporting mechanism, comprise bearing support, wheel carrier and auxiliary wheel body, auxiliary wheel body is rotatably connected on wheel carrier, it is characterized in that: turning axle is straight up installed in described wheel carrier upper end, this turning axle is rotatably installed in bearing support through cover slewing bearing thereon;
Described revolution shaft lower end is shaped with positioning step II, and upper end is shaped with a circle jump-ring slot II, and described slewing bearing lower end is supported in positioning step II, and the axle of bearing upper end in being installed on jump-ring slot II locked with jump ring;
Described inner hole of bearing seat upper end is shaped with positioning step I, and endoporus lower end is shaped with a circle jump-ring slot I, and positioning step I is withstood in described slewing bearing upper end, and lower end is locked by the hole jump ring being installed in jump-ring slot I.
Described slewing bearing comprises an outer ring and two inner rings, is embedded with a circle tapered roller along interior ring outer wall, and two inner rings are assemblied in described outer ring, and on two inner rings, tapered roller is arranged in opposite directions, between inner ring and outer ring, are marked with lubricating grease.
Between described slewing bearing two ends, Internal and external cycle, be provided with dust-proof seal ring.
Described slewing bearing upper end and axle are with being lined with pad between jump ring.
The invention has the beneficial effects as follows: 1, the present invention coordinates the location, the installation that realize slewing bearing with jump ring by positioning step, compare tradition revolution supporting mechanism fitting operation and greatly simplify.2, slewing bearing self inside that the present invention uses is marked with lubricating grease, and two ends are with dust-proof seal ring, have good dust-proof lubricating performance, effectively improves the working life of revolution supporting mechanism.3, in actual conditions uses, the normal load from vehicle body is finally delivered on auxiliary wheel body through bearing support, outer ring, rolling element, inner ring, turning axle, wheel carrier, and load can't, by jump ring or axle jump ring transmission for hole, therefore can adapt to severe duty.
