Abstract
The invention discloses a cylinder roller bearing with fine spiral embossments. The cylinder roller bearing comprises a bearing outer ring, a bearing inner ring, a retainer and cylinder rollers, wherein fine spiral embossments storing lubricants are processed on the surface of each cylinder roller and comprise levorotatory fine spiral embossments and dextrorotatory fine spiral embossments; the number of the levorotatory cylinder rollers is equal to that of the dextrorotatory cylinder rollers; and the levorotatory cylinder rollers and the dextrorotatory cylinder rollers are arranged between the bearing outer ring and the bearing inner ring at interval. The cylinder roller bearing has the advantages that the lubricants are stored in fine spiral embossments uniformly distributed on roller bodies, and after the bearing operates, full and uniform lubrication among the roller bodies, the inner ring and the outer ring can be realized so as to improve the lubricating performance of the bearing and be beneficial to prolonging the service life of the bearing; the lubricants are stored in fine spiral embossments uniformly distributed on the roller bodies so as to be beneficial to reducing the frictional wear of the bearing; and the levorotatory and dextrorotatory grooved rollers are uniformly distributed at interval so as to drive circulation of the lubricants and be beneficial to radiation, uniform distribution of the lubricants and prolonging of the service life.
Description
Technical field
The present invention relates to a kind of roller bearing, especially relate to a kind of roller bearing with taenidium stream.
Background technique
Bearing through rolling element will turn round the axle and axle bed between sliding friction become rolling friction, thereby reduced frictional loss.Rolling element is evenly distributed in by means of retainer between the inner ring and outer ring of bearing, and its shape, size and quantity directly affect the usability and the life-span of rolling bearing.At present, mainly be to consider lubricating between Internal and external cycle and the rolling element to the lubricated of bearing.Oiling agent in the bearing is uneven distribution normally, and the oiling agent of bearing end can not get into the contact area, has reduced the whole greasy property of bearing, has also reduced the service time of contact area in-lubricant to a certain extent.
Based on above-mentioned background, under the situation that does not reduce the rolling element bearing capacity, if the rolling element surface energy is evenly stored oiling agent; Then during bearing working; Lubricated when can realize between rolling element and inner ring, the outer ring, reduce friction, wearing and tearing, the life-span that helps improving bearing.Simultaneously,, can promote the cycle of oiling agent if in the operation process of rolling element, then help between rolling element and inner ring, the outer ring sufficient lubrication, the working life that helps improving oiling agent.
Summary of the invention
The object of the present invention is to provide a kind of roller bearing with taenidium stream, the ability kind of lubricant storage also gets into smooth the lubricant circulates in the bearing, improves the working lubrication performance of bearing and the working life of oiling agent.
The technological scheme that the present invention adopted is:
The present invention includes bearing outer ring, bearing inner race, retainer and cylindrical roller; The taenidium stream that kind of lubricant storage is arranged in each cylindrical roller surface Machining.
Described taenidium flow point is two kinds of left-handed and dextrorotation, and the cylindrical roller with left-handed taenidium stream equates with the cylindrical roller quantity with right hand helix silk stream, is installed between bearing outer ring and the bearing inner race at interval.
Described taenidium stream evenly distributes on the cylindrical roller surface; The working depth scope of silk stream be 0.05～0.8
, the helix angle scope is 1 °～70 °.
The beneficial effect that the present invention has is:
1) equally distributed taenidium stream stores oiling agent on the rolling element, behind the bearing operation, can realize full and uniform lubricated between rolling element and inner ring, the outer ring improving the bearing lubrication performance, helps improving bearing working life;
2) equally distributed taenidium stream stores oiling agent on the rolling element, helps reducing the fretting wear of bearing;
3) it is evenly spaced apart with the cylindrical roller with right hand helix silk stream to have a cylindrical roller of left-handed taenidium stream, has promoted the circulation of oiling agent, helps dispelling the heat, the even distribution of oiling agent and the raising in working life.
Description of drawings
Fig. 1 is the roller bearing schematic representation of band taenidium stream.
Fig. 2 is the left-handed taenidium distributions schematic representation of cylindrical roller.
Fig. 3 is the right hand helix silk distributions schematic representation of cylindrical roller.
Among the figure: 1, the cylindrical roller of left-handed taenidium stream; 2, the cylindrical roller of right hand helix silk stream.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1, comprise bearing outer ring, bearing inner race, retainer and cylindrical roller; The taenidium stream that kind of lubricant storage is arranged in each cylindrical roller surface Machining.
Like Fig. 2, shown in Figure 3; Described taenidium flow point is two kinds of left-handed and dextrorotation; The cylindrical roller 1 and cylindrical roller 2 that promptly have left-handed taenidium stream with right hand helix silk stream; Cylindrical roller 1 with left-handed taenidium stream equates with cylindrical roller 2 quantity with right hand helix silk stream, is installed between bearing outer ring and the bearing inner race at interval.
Like Fig. 2, shown in Figure 3; Described taenidium stream evenly distributes on the cylindrical roller surface; Silk flow depth degree be 0.05～0.8
; Fig. 2, silk stream helix angle
shown in Figure 3 all are 15 °, and the machining range of silk stream helix angle
is 1 °～70 °.
It is emphasized that the taenidium stream on the cylindrical roller forms through grinding or grinding, size is small, does not influence the surface roughness of rolling element, also can not reduce the integrated carrying ability of rolling element.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
