By using above-mentioned technical proposal, using mixed roller designs, ceramics are harder, and more wear resistant, ceramic roller is close Degree is more much smaller than steel roller density, and the coefficient of friction of ceramic roller is much smaller relative to steel roller, the effective height for improving bearing Fast performance and low friction moment performance, steel roller intensity is more preferable, so that bearing has preferable load-carrying ability, in taper roller When being a plurality of, steel roller, in being successively arranged alternately, prevents bias with ceramic roller;It is more when taper roller is odd number A taper roller out uses special porcelain packet roller designs, and porcelain packet roller takes into account bearing capacity, dynamic balancing, while having guarantee The high-revolving effect of bearing.
Preferably, the retainer includes the taper steel tubular frame body for being uniformly distributed circumferentially pocket hole, taper tubular The small end of frame body is equipped with the small end flange to internal diameter side to overturn, on the taper tubular frame body between two neighboring pocket hole Beam excircle side wall is equipped with oil storage tank, and oil storage tank extends along beam length direction, and the cross sectional shape of oil storage tank is that bottom is small, mouth is big Isosceles trapezoid.Under structure design, oil storage tank makes that lubricating oil can be stored at retainer, to improve greasy property, improves axis Forward speed.
Preferably, the taper roller guidance raceway big end on the inner ring outer circumference surface is equipped with big end rib, big end rib Roller contact face towards taper roller guidance raceway is convex arc surface, and convex arc surface is contacted with the big end end face of taper roller matches It closes.Under structure design, big end rib is supported using convex arc surface and the big end in contact of taper roller, to reduce contact surface Product, improves the speed of bearing operation.
Preferably, the taper roller on the inner ring outer circumference surface guides and is equipped with jump-ring slot at raceway small end, in jump-ring slot Equipped with the backstop circlip with taper roller small end end face counter stopper.Under structure design, direct shape on traditional inner ring is removed It is designed at small end rib, substitution small end rib is designed using backstop circlip, facilitates the assembly of bearing.
The utility model is further described with reference to the accompanying drawing.

Specific embodiment
Referring to attached drawing 1, a kind of tapered roller bearing of mixed type rolling element disclosed by the utility model, including it is outer ring 1, interior Circle 2, taper roller 3 and retainer 4, taper roller 3 are held between outer ring 1 and inner ring 2 through retainer, the circular cone rolling Son 3 includes steel roller 31 and lightweight roller, as shown in Figure 1, the taper roller is a plurality of, steel roller and lightweight roller In being successively arranged alternately, lightweight roller is ceramic roller 32.
As shown in Figures 2 and 3, the taper roller is odd number, and lightweight roller is compared with more than 31 one, steel roller, lightweight rolling Attached bag includes ceramic roller 32 and porcelain packet roller 33, and the ceramic roller 32 is identical as 31 quantity of steel roller, and steel roller 31 with ceramic roller 32 in being successively arranged alternately, porcelain packet roller 33 is set between steel roller 31 and ceramic roller 32, the porcelain Packet roller 33 includes cylinder steel lantern ring 331, and 331 center-filled of cylinder steel lantern ring has ceramics pole 332, cylinder steel lantern ring 331 outer circumference surfaces are equipped with ceramic coating 333.Using mixed roller designs, ceramics are harder, and more wear resistant, ceramic roller is close Degree is more much smaller than steel roller density, and the coefficient of friction of ceramic roller is much smaller relative to steel roller, the effective height for improving bearing Fast performance and low friction moment performance, steel roller intensity is more preferable, so that bearing has preferable load-carrying ability, in taper roller When being a plurality of, steel roller, in being successively arranged alternately, prevents bias with ceramic roller;It is more when taper roller is odd number A taper roller out uses special porcelain packet roller designs, and porcelain packet roller takes into account bearing capacity, dynamic balancing, while having guarantee The high-revolving effect of bearing.
