Description
Technical field
The utility model relates to a kind of fork truck bearing unit, particularly a kind of double-row full-complement angular contact ball fork truck bearing unit with high load capacity.
Background technique
During the fork truck bearing working, roller body low speed in the forklift mast track rolls, and the rake lifting of guiding fork and the tilting moment of bearing whole load-carryings of fork rake and support thereof and producing due to the load-carrying deflection require bearing can bear heavy duty in guide rail spacing space.Common shaft bearing outer-ring or guide wheel body+standard rolling bearing structure realization are widened, thickeied to normal the employing.
Satisfy load bearing requirements in the confined space, except increasing fork truck bearing wheel body (or outer ring) wall thickness, under steel ball size and garden, center, place diameter one stable condition thereof, steel ball number is more, and bearing capacity is larger.Be to increase steel ball number in bearing, prior art how adopts offer filling slot on the inside and outside circle rib diameter of bearing and through it to the more steel ball of bearing inside filling.After opening filling slot, single row bearing only can bear the one direction thrust load, and double row bearing is lost the thrust load ability, only can bearing radial force.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of double-row full-complement angular contact ball fork truck bearing unit with high load capacity.
For achieving the above object, the utility model is by the following technical solutions:
a kind of fork truck bearing unit, comprise roller body and bearing, it is characterized in that: described bearing comprises an inner ring, halved body outer ring and several rolling elements, the outer wall of described inner ring is provided with at least one bear inner ring grooved railway, described halved body outer ring merges becomes the outer ring, the inwall of described outer ring is provided with the outer ring raceway corresponding with bear inner ring grooved railway, in described rolling element is filled in, be full dress shape between outer ring raceway, the outer wall of described outer ring is provided with an annular groove, place the elastic ring that makes the halved body outer ring close up in this annular groove, described bearing is filled in the center hole of described roller body and interference fit, described center hole one end is provided with rib and the outer ring one end location that offsets.
Technique scheme can also be further improved by following technical measures.
Described bearing two ends are provided with seal ring.
On described inner ring inwall, 1/2 width place arranges the circular groove that can carry lubricant grease.
On described inner ring outer surface 1/2 width place be provided with at least one communicate with circular groove and run through the inner ring wall radially feed the fat passage.
Should feed the fat passage is a circular hole.
The quantity of described inside and outside circle raceway groove is respectively two, and described rolling element is two row and completely fills shape.
Described rolling element is steel ball.
Abovementioned technology can be selected a use, also use capable of being combined.
Present technique is born radially, axially or the fork truck bearing application demand of tilting moment for need, and a kind of heavily loaded double-row full-complement ball fork truck bearing unit is provided, and has maximum load-carrying capacity satisfying under same spacing space.Bearing unit can bear radial and axial heavier load or impact load, tilting moment by roller body+completely fill double-row angular contact bal bearing to form.
Description of drawings
Fig. 1 is that of the present utility model cuing open shown structural representation;
Fig. 2 is the three-dimensional exploded view of bearing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
referring to Fig. 1, 2, a kind of fork truck bearing unit, comprise roller body 1 and bearing 2, described bearing 2 comprises an inner ring 21, halved body outer ring 221, 222 and several rolling elements 23, the outer wall of described inner ring 21 is provided with two bear inner ring grooved railway 211, described halved body outer ring 221, 222 merging become outer ring 22, the inwall of described outer ring 22 is provided with two outer ring raceway 223 corresponding with bear inner ring grooved railway 211, in described rolling element 23 is filled in, be two row between outer ring raceway and completely fill shape, the outer wall of described outer ring 22 is provided with an annular groove 26, place in this annular groove and make halved body outer ring 221, 222 elastic rings that close up 27, described bearing 2 is filled in the center hole of described roller body 1 and interference fit, described center hole one end is provided with rib 11 and the outer ring 22 1 ends location that offsets.Described rolling element 23 is steel ball.
Described bearing 2 two ends are provided with seal ring 24,25.
On described inner ring 21 inwalls, 1/2 width place arranges the circular groove 212 that can carry lubricant grease.
On described inner ring 21 outer surfaces 1/2 width place be provided with at least one communicate with circular groove and run through inner ring 21 walls radially feed fat passage 213.
Should feed the fat passage is a circular hole.
During to bearing internal feed lubricating grease, lubricating grease is delivered to through circular groove 212 and feeds fat passage 213 when the greasing hole of using the greasing apparatus through being arranged on bearing installation shaft core.
Roller body 1 is a heavy wall roller, and its external diameter surface can coordinate the guide rail shape to be designed to cylindrical or circular arc, can directly roll along track.
22 outer surface 1/2 width places, bearing 2 outer ring are provided with annular groove 26, can place the elastic ring 27 that makes the halved body outer ring close up in groove, this elastic ring 27 can be O type rubber ring, first with O type rubber ring, halved body outer ring 221,222 is combined during bearing 2 assembling, can arbitrarily fills steel ball 23 until full the dress in two raceway grooves that inside and outside circle consists of by the elastic force of O type circle.Slight crack automatic capturing under the effect of O type rubber ring and steel ball 23 between halved body outer ring 221,222 resets simultaneously, forms the complete bearing 2 in flawless gap.
Be interference fit between bearing 2 external diameters and roller body 1 internal diameter, a whole set of bearing 2 under by pressure, O type rubber ring being kept is pressed in roller body 1, halved body outer ring 221,222 becomes intact integral outer ring 22 under thick and heavy roller body 1 inner wall pressure constraint, with inner ring 21, steel ball 23 and the common double-row full-complement angular contact ball fork truck bearing unit that forms high load capacity of roller body 1.
In the effectively lubricating that forms between two seal rings 24,25 that bearing 2 two ends arrange, seal space, filling is fit to the lubricating grease of working condition requirement, can effectively stop on guide rail dirt to enter the inner and proper lubrications of bearing 2.
By being arranged on feeding fat passage 213 and carrying the circular groove 212 of grease on bearing 2 inner rings 22, can feed as required fresh lubricating grease, when replenishing bearing 2 work because of friction and the heating consumption to grease.
Be only below that the specific embodiment in the utility model is illustrated, every equivalent transformation or modification of making according to the design concept in the utility model all should be thought to fall into protection domain of the present utility model.
