Abstract
The utility model relates to a roller bearing, which comprises an outer ring, an inner ring, retainers and a rolling body, wherein a transfer ring is arranged between the outer ring and the inner ring; a rolling ball type rolling body and a roller type rolling body are separately arranged between the outer ring and the transfer ring and between the inner ring the transfer ring; the rolling body comprises a first retainer and a second retainer which are separately corresponding to the rolling ball type rolling body and the roller type rolling body. The roller bearing is characterized in that oil storage grooves, in which lubricating oil is stored, are formed at two sides of the outer ring and are arranged symmetrically to the rolling body; a radial oil through groove for communicating the roller ball type rolling body and the roller type rolling body is formed in the transfer ring. The utility model aims at providing the roller bearing; the problem that lubricating oil filling of a double-layer structure roller bearing is inconvenient is solved; the roller bearing is simple and reasonable in structure, rapid filling is convenient and effective and rapid lubricating of the double-layer rolling body is facilitated.
Description
Technical field
The utility model relates to a kind of roller bearing field.
Background technique
At present, the roller bearing that people use is to adopt individual layer rolling element mostly, roller bearing can provide stronger radially bearing capacity with respect to ball bearing, but the greatest limit speed of roller bearing is less with respect to ball bearing, therefore the roller bearing speed of individual layer rolling element has also just been subject to the restriction of rolling element in prior art; How to make to ensure that it is the problem that prior art runs into that roller bearing can provide maximized limit speed.
Claimant has submitted the application of the structure that layer rolling axon holds simultaneously, in arranging between outer ring and inner ring, turn-take, outer ring and in turn-take and inner ring and in ball-type rolling element and roller-type rolling element are set respectively between turn-taking; Rolling element comprises the first corresponding with ball-type rolling element and roller-type rolling element respectively retainer and the second retainer; Such structure can address the above problem, but exists the problem that is difficult to charging-up lubricant oil.
Model utility content
For the deficiency existing in background technique, the utility model object is a kind of roller bearing, can solve the problem of the oil filling inconvenience of double layer construction roller bearing, simultaneously the utility model is simple and reasonable, is convenient to annotate fast and is conducive to effective fast lubricant of layer rolling body.
For achieving the above object, the utility model provides following technological scheme: a kind of roller bearing, comprises outer ring, inner ring, retainer and rolling element; In arranging between outer ring and inner ring, turn-take, outer ring and in turn-take and inner ring and in ball-type rolling element and roller-type rolling element are set respectively between turn-taking; Rolling element comprises the first corresponding with ball-type rolling element and roller-type rolling element respectively retainer and the second retainer; It is characterized in that: both sides, described outer ring offer and are symmetrical in that rolling element is arranged and storage inside and have the oil storage tank of lubricant oil; The upper setting of turn-taking in described is communicated in the radially logical oil groove of ball-type rolling element and roller-type rolling element.
The utility model is also further set to: the external port of described oil storage tank is provided for the block rubber of shutoff.
The utility model is also further set to: described radially logical oil groove in turn-take on multiple annulars equidistantly arrange.
The utility model is also further set to: the multiple equidistant settings on the circumferential surface of place, both sides, outer ring of described oil storage tank.
The beneficial effects of the utility model: bearing is lubricated while safeguarding at needs, only need to be lubricated oily filling to oil storage tank corresponding to outer ring, ball-type rolling element can be lubricated by radially logical oil groove lubricant oil in the process of motion to roller-type rolling element; After filling, can pass through the external port of block rubber shutoff oil storage tank; During multiple radially logical oil groove annulars are equidistantly arranged at, turn-take in the radial direction, can accelerate lubricating roller-type rolling element; Multiple oil storage tanks of both sides, outer ring can increase oil reserve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Number in the figure implication: 1-outer ring; 11-oil storage tank; 111-block rubber; In 2-, turn-take; The radially logical oil groove of 21-; 3-inner ring; 4-ball-type rolling element; 5-the first retainer; 6-roller-type rolling element; 7-the second retainer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of roller bearing, comprises outer ring 1, inner ring 3, retainer and rolling element; In arranging between outer ring 1 and inner ring 3, turn-take 2, outer ring 1 and in turn-take 2 and inner ring 3 and in turn-take ball-type rolling element 4 and roller-type rolling element 6 be set respectively between 2; Rolling element comprises the first corresponding with ball-type rolling element 4 and roller-type rolling element 6 respectively retainer 5 and the second retainer 7; 1 both sides, described outer ring offer and are symmetrical in that rolling element is arranged and storage inside and have the oil storage tank 11 of lubricant oil, the multiple equidistant settings on 1 place, the both sides circumferential surface of outer ring of described oil storage tank 11, and the external port of described oil storage tank 11 is provided for the block rubber 111 of shutoff; In described, turn-take the radially logical oil groove 21 that is communicated in ball-type rolling element 4 and roller-type rolling element 6 be set on 2, described radially logical oil groove 21 in the multiple annulars on 2 of turn-taking equidistantly arrange.
The working principle of the present embodiment: bearing is lubricated while safeguarding at needs, only need to be lubricated oily filling to the oil storage tank 11 of outer ring 1 correspondence, ball-type rolling element 4 can be lubricated by radially logical oil groove 21 lubricant oil in the process of motion to roller-type rolling element 6; After filling, can pass through the external port of block rubber 111 shutoff oil storage tanks 11; During multiple radially logical oil groove 21 annulars are equidistantly arranged at, turn-take 2 in the radial direction, can accelerate lubricating roller-type rolling element 6; Multiple oil storage tanks 11 of 1 both sides, outer ring can increase oil reserve.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these of above-mentioned hypothesis improve and modification also should be considered as protection domain of the present utility model.
