Abstract
The utility model discloses a roller bearing, which comprises a bearing outer ring, wherein a bearing inner ring is arranged inside the bearing outer ring, an upper baffle ring is arranged on the inner side of the upper end of the bearing outer ring, and a lower baffle ring is arranged on the outer side of the lower end of the bearing inner ring. The technical scheme is that a plurality of cylindrical rollers are arranged between the bearing outer ring and the bearing inner ring, a plurality of axial grooves arranged at intervals are disposed outside the bearing inner ring, and the cylindrical rollers are installed in the axial grooves. The cylindrical rollers are contacted with groove walls on two sides of the axial grooves and the inner side of the bearing outer ring, and gaps are formed between the cylindrical rollers and the groove bottom of the axial grooves. The roller bearing aims at overcoming defects in the prior art, can bear heavy load alternating load, and has good lubricity, simple structure and long service life.
Description
[technical field]
The present invention relates to a kind of bearing, a kind of roller bearing of more specifically saying so.
[background technique]
The heavy-duty machinery field, like wind-power electricity generation, industries such as fluid machinery and heavy machinery all must be used bearing.The bearing that under heavily loaded alternate load operating mode, uses, often the effect owing to heavy alternating stress causes the wearing and tearing of roller and the destruction of oil film, and greatly reduce the working life of bearing.
[summary of the invention]
The present invention seeks to overcome the deficiency of existing technology, provide a kind of and can bear heavily loaded alternate load, lubricity is good, and is simple in structure, the roller bearing of long service life.
The present invention realizes through following technological scheme:
A kind of roller bearing; Comprise bearing outer ring 1; Be provided with bearing inner race 2 in the described bearing outer ring 1; The inboard, upper end of described bearing outer ring 1 is provided with upper baffle ring 102, and described bearing inner race 2 lower outside are provided with lower baffle ring 203, it is characterized in that: be provided with a plurality of cylindrical rollers 3 between described bearing outer ring 1 and the described bearing inner race 2; Described bearing inner race 2 outsides are provided with the axial notch 201 that a plurality of intervals are provided with; Described cylindrical roller 3 is contained in the described axial notch 201, the interior side contacts of described cylindrical roller 3 and described axial notch 201 both sides cell walls and described bearing outer ring 1, and described cylindrical roller 3 forms gap 4 with described axial notch 201 bottom lands.
Aforesaid roller bearing is characterized in that: described axial notch 201 is arc groove.
Aforesaid roller bearing is characterized in that: described bearing outer ring 1 is provided with a plurality of attachment holes 101.
Aforesaid roller bearing is characterized in that: described bearing inner race 2 is provided with a plurality of inner ring attachment holes 202.
Aforesaid roller bearing is characterized in that: the minimum width in described gap 4 is at least 0.3mm.
Compared with prior art, the present invention has following advantage:
1, cylindrical roller of the present invention has two place's lines to contact with the peripheral axial notch of bearing inner race, and stress performance is good, can bear heavy load.
2, cylindrical roller of the present invention and bottom portion of groove form narrow gap, and oil storage and lubricating bearings cylindrical roller are convenient in this gap.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is a B-B sectional view of the present invention;
Fig. 3 is an I of the present invention portion enlarged view.
[embodiment]
A kind of roller bearing; Comprise bearing outer ring 1; Be provided with bearing inner race 2 in the described bearing outer ring 1, the inboard, upper end of described bearing outer ring 1 is provided with, and described bearing inner race 2 lower outside are provided with lower baffle ring 203; Be provided with a plurality of cylindrical rollers 3 between described bearing outer ring 1 and the described bearing inner race 2; Described cylindrical roller 3 is stuck between upper baffle ring 102 and the lower baffle ring 203, and described bearing inner race 2 outsides are provided with the axial notch 201 that a plurality of intervals are provided with, and described cylindrical roller 3 is contained in the described axial notch 201; The interior side contacts of described cylindrical roller 3 and described axial notch 201 both sides cell walls and described bearing outer ring 1, described cylindrical roller 3 forms gap 4 with described axial notch 201 bottom lands.
Described axial notch 201 is an arc groove.
Described bearing outer ring 1 is provided with a plurality of attachment holes 101.
Described bearing inner race 2 is provided with a plurality of inner ring attachment holes 202.
The minimum width in described gap 4 is at least 0.3mm.Seal ring is equipped with in both sides on bearing outer ring.
The periphery of bearing inner race of the present invention is uniform-distribution with the groove that can hold cylindrical roller; Holding cylindrical roller in the groove; Outer cover at bearing inner race and cylindrical roller bearing outer ring, and cylindrical roller has two place's lines to contact with the peripheral inside grooves of bearing inner race, and the bottom portion of groove on the non-contact face of cylindrical roller and the bearing inner race forms narrow gap; This gap can be used for storing lubricating oil, and cylindrical roller has a place to contact with the bearing outer ring inboard.The present invention has removed the retainer of traditional bearing; Through groove is set on bearing inner race; Not only simplified mounting process, and because the load that cylindrical roller by the even interval of groove, makes each roller transmit is more even; Can improve the working life of bearing, be used in especially under the load working condition of alternation heavy duty.The present invention adopts the mode of three contacts, and narrow gap is formed on the bottom of cylindrical roller and bearing inner race, is used for storing lubricating oil, is used for lubricated to cylindrical roller.The present invention can simplify process Installation, makes load distribution even, increases the carrying integrity of bearing, and it is strong to have bearing capacity, high life, and low cost and other advantages, the load working condition that is adapted at heavily loaded alternation uses down.
