Abstract
The invention relates to a bearing suitable for the addition of lubricating oil. The bearing comprises a bearing outer ring, a bearing inner ring and a roller, wherein the roller is arranged in a groove between the bearing outer ring and the bearing inner ring; a circle of fan blades are fixed on one side of the bearing inner ring; and the fan blades have the following characteristic in direction: when the bearing inner ring rotates in a preset direction, the fan blades generate air flow which comes from the non-fan blade side of the bearing inner ring to the fan blade side. Lubricating oil can be effectively added in the bearing when the rotation shaft rotates, so that the bearing can adapt to the requirement of the actual production more flexibly.
Description
Affiliated technical field
The present invention relates to the mechanical fitting field, particularly, is a kind of bearing that can add lubricant oil in the rotating shaft rotary course.
Background technique
At mechanical field, bearing is various driven off by shaft basic accessories, mainly is divided into sliding bearing and rolling bearing.And present bearing includes inner ring, outer ring, and rolling bearing also comprises the roller structure between the Internal and external cycle.
Because during the rotating shaft rotation, therefore relative quick rotation between bearing inner race and the outer ring need make to keep lubricated preferably between the two, with the resistance of reducing friction.Yet, when present bearing is lubricated, can only under the situation that rotating shaft stops, carrying out, if add lubricant oil when rotating shaft is rotated, because centrifugal action, lubricant oil will outwards splash, thereby be difficult to reach good lubricating effect.Therefore, present bearing can not add lubricant oil neatly, can not fully satisfy the demand of actual production.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of bearing of being convenient to add lubricant oil, this bearing can be realized the interpolation of lubricant oil effectively when rotating shaft is rotated, make the demand that it more can the flexible adaptation actual production.
The technical solution adopted for the present invention to solve the technical problems is: this bearing comprises bearing outer ring, bearing inner race, roller, described roller is located in the groove between described bearing outer ring and the bearing inner race, the fixed circle flabellum of one side of described bearing inner race, the direction of described flabellum has following characteristics: when described bearing inner race was pressed the predetermined direction rotation, described flabellum produced the air-flow from the non-flabellum side of described bearing inner race to the flabellum side.
As preferably, described roller is a cylindrical body, and has through hole along axis, to guarantee having unobstructed air channel between described bearing outer ring and the bearing inner race.
As preferably, described flabellum is the bullion sheet, is welded on the described bearing inner race.
As preferably, described bearing inner race exceeds the end face of described bearing outer ring at the end face of non-flabellum side, and described bearing inner race outside this side has thick in thin tapering, thereby make it on morpheme, to be convenient to add lubricant oil.
Beneficial effect of the present invention is: above-mentioned bearing is with after rotating shaft matches, under the state of rotating shaft rotation, can directly add lubricant oil in the non-flabellum side of described bearing inner race, because described flabellum in rotary course, produces the air-flow from the non-flabellum side of described bearing inner race to the flabellum side, therefore, lubricant oil is under the traction of this air-flow, overcome the strength that extends out, thereby enter the roller structure in the middle of described bearing inner race and the bearing outer ring, play good lubrication by the centrifugal action generation.This bearing can be realized the interpolation of lubricant oil effectively when rotating shaft is rotated, make the demand that it more can the flexible adaptation actual production.
Description of drawings
Fig. 1 is this vertical profile structural drawing of being convenient to add the bearing of lubricant oil.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Fig. 1, embodiment illustrated in fig. 2 in, this bearing comprises bearing outer ring 1, bearing inner race 2, roller 3, described roller 3 is located in the groove between described bearing outer ring 1 and the bearing inner race 2, the fixed circle flabellum 21 of one side of described bearing inner race 2, the direction of described flabellum 21 has following characteristics: when described bearing inner race 2 is pressed the predetermined direction rotation, and the air-flow that described flabellum 21 produces from described bearing inner race 2 non-flabellum sides to the flabellum side.
Above-mentioned bearing, described roller 3 is a cylindrical body, and has through hole along axis, to guarantee having unobstructed air channel between described bearing outer ring 1 and the bearing inner race 2, in order to guarantee the intensity of described roller 3, the diameter of its through hole is unsuitable excessive, is no more than 1/2nd of described roller 3 diameters.
Above-mentioned bearing, described flabellum 21 is the bullion sheet, is skewed and is welded on the described bearing inner race 2.
Above-mentioned bearing, described bearing inner race 2 exceeds the end face of described bearing outer ring 1 at the end face of non-flabellum 21 sides, and described bearing inner race 2 outside this side has thick in thin tapering, thereby make it on morpheme, to be convenient to add lubricant oil.
Above-mentioned bearing is with after rotating shaft matches, under the state of rotating shaft rotation, can directly add lubricant oil in the non-flabellum side of described bearing inner race 2, because described flabellum 21 in rotary course, produces the air-flow from described bearing inner race 2 non-flabellum sides to the flabellum side, therefore, lubricant oil is under the traction of this air-flow, overcome the strength that extends out, thereby enter the roller structure in the middle of described bearing inner race 2 and the bearing outer ring 1, play good lubrication by the centrifugal action generation.This bearing can be realized the interpolation of lubricant oil effectively when rotating shaft is rotated, make the demand that it more can the flexible adaptation actual production.
