Description
Technical field
The invention belongs to technical field of automobile, particularly relate to a kind of thrust-bearing rolling body.
Background technique
Bearing roller is the vitals in bearing, usual roller is arranged on retainer, retainer is for separating of each roller, keep roller spacing equal, make load mean allocation, during use, bearing roller rotates thus realizes the function of bearing inner race and outer ring mutually rotating between bearing inner race and bearing outer ring.Such as be used in the roller on thrust-bearing, due to the particularity of bearing roller shape, and roller contacts and phase mutual friction with retainer and bearing enclose all the time, the easy like this bearing roller that causes very easily weares and teares, in addition, existing bearing roller also also exists: poor stability, and bearing capacity is poor, the problems such as working life is short, roller lubrication degree difference.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of thrust roller bearing [application number: 201310085926.0], and thrust roller bearing comprises decile sector unit, locating stud, screw, roller, roller cage.Be assembled on installation base surface by manufactured decile sector unit, as required, mix roller and the roller cage of different size, thrust roller bearing just can be applied.Above-mentioned scheme improves the subproblem of prior art to a certain extent, such as, to some extent solve the problem that bearing roller cost of production is high, but, also at least there is following defect in the program: poor stability, bearing roller end is easy to wear, and roller lubrication degree is poor, and when circumference is rotated, stationarity is poor.
Summary of the invention
The object of the invention is for the problems referred to above, provide a kind of design more reasonable, the nonabradable thrust-bearing rolling body in roller end.
For achieving the above object, present invention employs following technical proposal: this thrust-bearing rolling body, comprise in circular cone column and there is the conical roller body of little head end and stub end, it is characterized in that, described conical roller body outer circumferential has at least one annular oil groove, at the center of the little head end end face of conical roller body, there is blind hole, the stub end end face of described conical roller body is provided with some equally distributed pits in a circumferential direction, and the pit of described blind hole described in when being projected on stub end end face is all positioned at the outer circumferential of blind hole projection, described blind hole is connected with the communicating passage coaxially arranged with conical roller body, and in described annular oil groove, be provided with some oilholes be connected with communicating passage, described communicating passage end is connected with some with pit connecting passage one to one, described connecting passage is all obliquely installed and circumference surrounds formation cone structure, and described communicating passage is connected with pit by connecting passage.The good stability when distribution of blind hole and pit can make conical roller body rotate, and wear and tear in end when can prevent conical roller body circumference from rotating, and blind hole can also be used for placing lubricant oil, and lubricant oil is delivered to pit by connecting passage, make conical roller body two ends lubricity good.
In above-mentioned thrust-bearing rolling body, the oilhole in each annular oil groove is all in a discrete distribution along helix.
In above-mentioned thrust-bearing rolling body, described pit is tapered, and the width of described pit outside to the width diameter of bottom diminishes; The depth size of described blind hole is greater than the depth size of pit.
In above-mentioned thrust-bearing rolling body, described annular oil groove is arranged on the middle and lower part of conical roller body near stub end.
In above-mentioned thrust-bearing rolling body, the quantity of described pit is four and circumference is uniformly distributed setting.
In above-mentioned thrust-bearing rolling body, form angle between the male cone (strobilus masculinus) of described conical roller body and conical roller body stub end end face, and the size of described angle is 75 °-85 °.
In above-mentioned thrust-bearing rolling body, described outer circumferential, conical roller body two ends is equipped with arc angling portion.
In above-mentioned thrust-bearing rolling body, be connected with the pit diameter of one end of the tapered and described connecting passage of described connecting passage diminishes gradually to the other end diameter.
Compared with prior art, the advantage of this thrust-bearing rolling body is: structure is simple, and can reduce the wearing and tearing of rolling body end, good stability, long service life, roller lubrication degree is good, and when roller rotates, stationarity is good.
