Description
Affiliated technical field
The utility model relates to field of bearings, is specifically related to a kind of built-in oil slot type rolling bearing.
Background technique
Bearing in the manufacturing of machinery, use extremely extensively, be to improve the most effective means in its working life to bearing lubricated, for the lubricated oil lubrication and the grease lubrication of mainly being divided into of bearing.The effect of oil lubrication is better; Can improve the working life of bearing to greatest extent, but oil lubrication needs special oil circuit design, also supporting equipment such as oil pump will be arranged; Simultaneously the sealed precision of machinery is had relatively high expectations, the cost of production that has improved equipment greatly rises this with operation.Though grease lubrication is not high to the structure and the precision requirement of equipment when making, can't flow owing to grease is solid-state, feasible bearing grease to its friction surface after using with grease lubrication constantly outwards pushes; Friction effect worse and worse; To the last can't form oil film, once more the grease that adds of having to, the working life of the bearing of grease lubrication is also short than the life-span of oil lubrication; More often change, cause great trouble for the user of equipment.Especially for some equipment that need run up, the bearing of grease lubrication is difficult to satisfy its rotating speed requirement.
Moving machinery in the present major part of China all is grease lubrication, along with the progress of equipment, high more over the large-scale rapid production requirement moon; These equipment are badly in need of improving its rotating speed and are adapted to market; And grease lubrication to rotating speed restriction, make that be difficult in old equipment improves and get to requirement, and buy new equipment; Price has too expensive, and this has restricted the development of enterprise greatly.
Summary of the invention
To above problem, the utility model provides a kind of bearing to carry oil groove the steel ball of bearing is lubricated, simultaneously convenient oiling built-in oil slot type rolling bearing.
The utility model solves the technological scheme that its technical problem adopted: this built-in oil slot type rolling bearing comprises inner ring, outer ring, steel ball, annular oil groove; In the track of said steel ball between inner ring and outer ring; Said annular oil groove is annular square tube, and its maximum outside diameter is identical with the external diameter of outer ring, and its minimum diameter is greater than the inner ring external diameter; Annular oil groove inner annular cavity is a shoe cream room; One or more oil dripping tubes that is uniformly distributed with are arranged at the annular oil groove bottom, and the oil inlet pipe with shoe cream room UNICOM is arranged at annular oil groove top, and lubricant oil is housed in the oil groove.
As preferably, the end opening of said oil dripping tube is positioned at the inboard of said outer ring.
As preferably, the oil suction material also is equipped with in said annular oil groove inside.
The beneficial effect of the utility model is: the annular oil groove on this built-in oil slot type rolling bearing top can oil storage, and the oil dripping tube through its underpart refuels on the steel ball in the middle of inner ring, the outer ring, need not fueling facilities such as oil pump like this; When machine works, refuel always; Use the equipment mechanism design of this band oil groove formula rolling bearing the time also not need special sealing oil circuit, reduced design this and manufacture cost, the form of drippage is adopted in the deadweight of use; Conservation of power and lubricant oil; Reduce production costs, it is simple in structure, and is similar with deep groove ball bearing; Convenient in application in the transformation process of present machinery helps utilizing existing equipment to improve production capacity to greatest extent.
Description of drawings
Fig. 1 is the cross-sectional view of built-in oil slot type rolling bearing.
Embodiment
Below in conjunction with embodiment the utility model is further specified:
As shown in Figure 1, built-in oil slot type rolling bearing among the embodiment comprises inner ring 1, outer ring 2, steel ball 3, in the track of said steel ball 3 between inner ring 1 and outer ring 2; It is characterized in that: this built-in oil slot type rolling bearing also comprises annular oil groove 4; Said annular oil groove 4 is annular square tube, and its maximum outside diameter is identical with the external diameter of outer ring 2, and its minimum diameter is greater than inner ring 1 external diameter; Annular oil groove 4 inner annular cavitys are shoe cream room 41; One or more oil dripping tubes that is uniformly distributed with 42 are arranged at annular oil groove 4 bottoms, and the oil inlet pipe 5 with shoe cream room 41 UNICOMs is arranged at annular oil groove 4 tops, and lubricant oil 6 is housed in the oil groove.
Originally it is similar to execute in the example built-in oil slot type rolling bearing structure and deep groove ball bearing; When concrete the manufacturing; The size of each parts such as inner ring 1, outer ring 2, steel ball 3 can be made with reference to the manufacturer's standard of deep groove ball bearing in the present embodiment, and it is main is not both annular oil groove 4 structures, and the shoe cream room 41 in the middle of this annular oil groove 4 is when built-in oil slot type rolling bearing is worked; To shoe cream room 41, add lubricant oil from oil inlet pipe 5; And oil dripping tube 42 is the capillary oil pipe, and lubricant oil 6, drips from oil dripping tube 42 infiltrations owing to action of gravity from shoe cream room 41.Refuel in the shoe cream room 41 and once can for oil dripping tube 42 drippages for a long time carve through oil pump so when not required and refuel, just can realize saving lubricant oil that so also can be a large amount of to built-in oil slot type rolling bearing to steel ball.
In addition, as shown in Figure 1, the end opening of said oil dripping tube 42 is positioned at the inboard of said outer ring 2.Shoe cream room 41 just can give the steel ball 3 in the work oily in the place track of the steel ball 3 on the interior side inflow outer ring 2 of outer ring 2 through the lubricant oil 6 of oil dripping tube 42 infiltration drippages like this.And the tracks of steel ball 3 is main rubbing surfaces, and the lubricant oil of adding drips inflow wherein just, can reach maximum like this to the utilization of lubricant oil.Said annular oil groove 4 internal conditions need to pack into oil suction material 7.Can reduce the dropleting speed of lubricant oil 6 in the shoe cream room 41 so to greatest extent, the consumption of lubricant oil is more economized.
Present embodiment built-in oil slot type rolling bearing notes when using; Different with common deep groove ball bearing, its installation has directivity, promptly must as scheme assembling up and down; Cannot assemble conversely or laterally; Have only assembling up and down, said annular oil groove 4 could guarantee that like this lubricant oil 6 is from annular oil groove 4 bottom oil dripping tubes 42 drippages up.Said oil inlet pipe 5 can be connected with oil-filling device, adopts gradually continuous property oiling.Because its lubricant oil utilization ratio is high, each shoe cream room 41 is filled it up with lubricant oil and can be used for a long time.
And because this built-in oil slot type rolling bearing is similar with deep groove ball bearing; So convenient in application in the transformation process of present machinery; The mode of its oil lubrication can improve the rotating speed of equipment greatly, reduces wearing and tearing; Improve service life of equipment, help utilizing existing equipment to improve production capacity to greatest extent.
