Abstract
The utility model discloses a cylindrical roller bearing with spiral thread flow. The cylindrical roller bearing with the spiral thread flow comprises a bearing outer ring, a bearing inner ring, a retainer and cylindrical rollers. A surface of each cylindrical roller is provided with the spiral thread flow used to store lubricant, and the spiral thread flow is divided into a left-rotation type and a right-rotation type. The left-rotation cylindrical rollers and the right-rotating cylindrical rollers are the same in number and arranged between the bearing outer ring and the bearing inner ring at intervals. By means of the cylindrical roller bearing with the spiral thread flow, the spiral thread flow evenly distributed on a rolling element is stored with the lubricant, after process of bearing operation, the lubricant can achieve full lubrication between the rolling element and the inner ring and the outer ring, and therefore a lubrication property of the bearing is improved and service life of the bearing is prolonged. The spiral thread flow evenly distributed on the rolling element is stored with the lubricant, and the cylindrical roller bearing with the spiral thread flow is beneficial to reduce friction wear of the bearing. Rollers of opening grooves of the left-rotation and the right-rotation distributed at even intervals drive circulation of the lubricant, and are beneficial for heat-dissipation and even distribution of the lubricant and prolonging service life.
Description
Technical field
The utility model relates to a kind of roller bearing, especially relates 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 purpose of the utility model is to provide a kind of roller bearing with taenidium stream, and 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 utility model adopted is:
The utility model comprises 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 utlity model 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 utility model 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 utility model of explaining; Rather than the utility model limited; In the protection domain of the spirit of the utility model and claim,, all fall into the protection domain of the utility model to any modification and the change that the utility model is made.
