Abstract
The utility model discloses a tapered roller bearing, which comprises a bearing cup, a bearing cone, a basket cage and a rolling element, wherein, a flange is connected on the outside diameter of a big flange of the bearing cone, and a small flange of the bearing cone is widened outwards to form a broad edge. The widened breadth of the small flange of the bearing cone is the breadth needed by a space ring. An oil deflector structure is added at the big flange of the cone to reduce the outflow of lubricating oil, the amount of the lubricating oil in a bearing cavity is increased, particularly part of lubricating oil flows into the part between the spherical surface of the rolling element and the cone flange after being blocked by a boss, so as to increase the lubrication, and enable the formation of a dynamic oil film between the two. When assembling the bearing on a shaft, because the breadth of the small flange of the cone is extended, the original spacing ring is replaced, the number of parts is reduced, the assembly is simple, and the precision is improved.
Description
Technical field
The utility model relates to bearing technology, is specially a kind of tapered roller bearing.
Background technique
General tapered roller bearing in use, after lubricant oil enters into bearing inside, between inside and outside raceway and the rolling element, form lubricant film between rolling element and the inner ring rib, because the big oral area opening of conventional bearing is bigger, the inner ring rib edge is more shallow, from then on most of lubricant oil hold outflow, can not form effectively lubricating in the bearing cavity.In addition, the little rib of inner ring is equipped with separation sleeve outward, and the part number is many, and structure is loaded down with trivial details relatively.
The model utility content
Technical problem to be solved in the utility model is exactly to overcome lubricant oil can not form effectively lubricating in the bearing cavity problem, a kind of tapered roller bearing that provides structure to be simplified.
Technical problem of the present utility model adopts following technical proposals to solve:
A kind of tapered roller bearing comprises bearing outer ring, bearing inner race, basket shape retainer and rolling element, connects a flange on the described bearing inner race large-flange external diameter, and the little rib of bearing inner race is outwards widened and is a broadside.
The width that the little rib of described bearing inner race is widened is the width of required spacer ring.
The utility model increases by an oil baffle structure at inner ring large-flange place, reduce the outflow of lubricant oil, increase the amount of lubricant oil in the bearing bore, particularly make a part of lubricant oil after boss stops, flow between rolling element sphere and the inner ring rib, increase the lubricated of them, be convenient to form between the two dynamic pressure oil film.Bearing because the width of the little rib of inner ring has been done extension, has replaced original cage ring when assembling on axle, reduce the quantity of part, and assembling is simple, and precision improves.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated:
The utility model is a kind of tapered roller bearing, comprise bearing outer ring 1, bearing inner race 4, bearing osculum portion 2, the big oral area 7 of bearing, basket shape retainer 5 and rolling element 6, connect a flange 8 on the large-flange external diameter of bearing inner race 4, the little rib 3 of bearing inner race is outwards widened and is a broadside.The width of the little rib 3 of bearing inner race is the length of required cage ring.
Rolling element 6 is encased in basket shape retainer 5, and the bearing inner race 4 of packing into then utilizes mould that the three is combined as an integral body, with outer ring 1 and its combination, forms complete bearing at last.
Claims (1)
1. tapered roller bearing comprises bearing outer ring, bearing inner race, basket shape retainer and rolling element, it is characterized in that connecting on described bearing inner race (4) the large-flange external diameter flange (8), and the little rib of bearing inner race (3) is outwards widened and is a broadside.
