Abstract
The invention relates to a thrust roll-needle bearing. The thrust roll-needle bearing comprises an inner thrust piece, an outer thrust piece, a retaining frame and a roll needle, wherein the retaining frame is arranged between the inner thrust piece and the outer thrust piece; a clamping groove is arranged on the outer diameter of the inner thrust piece; and the inner diameter of the outer thrust piece is clamped into the clamping groove so as to limit the retaining frame between the inner thrust piece and the outer thrust piece. The thrust roll-needle bearing has the advantages that the inner diameter of the outer thrust piece is locked by the inner thrust piece, a locking opening is wide in size, high in strength and good in wear resistance, so that the lubricity of the bearing is improved, and the benefit for storing lubricating oil is achieved; and the thrust roll-needle bearing is applicable to relatively severer working conditions with higher rotating speed.
Description
Technical field
The present invention relates to field of bearings, particularly relate to a kind of needle roller thrust bearing.
Background technique
In band, the needle roller thrust bearing of extrapolability has interior thrusting plate 2 ', extrapolability sheet 1 ', retainer and needle roller 3 ' to form, as shown in Figure 1, this kind of thrust-bearing riveted construction is that internal force push jack 2 ' is locked in retainer internal diameter at present, extrapolability sheet 1 ' is locked in retainer outer diameter face, and this kind of structure is applicable to lower, the relatively stable operating mode of rotating speed.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the deficiencies in the prior art, provides a kind of needle roller thrust bearing, is applicable to that rotating speed is higher, the operating mode of rather harsh, and intensity is high, wear resistance good, lubricity is good, is conducive to storing up lubricant oil.
The technical solution adopted for the present invention to solve the technical problems is: a kind of needle roller thrust bearing, comprise interior thrusting plate, extrapolability sheet, be arranged on retainer between interior thrusting plate and extrapolability sheet and needle roller, described interior thrusting plate external diameter is provided with draw-in groove, and described extrapolability sheet inside caliper accesses in described draw-in groove to be limited between interior thrusting plate and extrapolability sheet by retainer.
In a preferred embodiment of the present invention, described interior thrusting plate comprises integrated inner clip plate and cylindrical first chuck, described first chuck external diameter is provided with draw-in groove, and described extrapolability sheet comprises outer plate and cylindrical second chuck, and described second chuck clamping enters in described draw-in groove.
In a preferred embodiment of the present invention, described first chuck external diameter end is provided with the fore shaft that can compress the second chuck.
The invention has the beneficial effects as follows: needle roller thrust bearing of the present invention pins extrapolability sheet internal diameter by interior thrusting plate, fore shaft size is wide, intensity is high, fore shaft wear resistance is good, thus improve the lubricity of bearing, be conducive to storing lubricant oil, this needle roller thrust bearing is applicable to that rotating speed is higher, the operating mode of rather harsh.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of needle roller thrust bearing in prior art;
Fig. 2 is the structural representation of needle roller thrust bearing of the present invention;
Fig. 3 is the close-up schematic view of I part in Fig. 2.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 2, a kind of needle roller thrust bearing, comprise interior thrusting plate 2, extrapolability sheet 1, be arranged on retainer 4 between interior thrusting plate 2 and extrapolability sheet 1 and needle roller 3, described interior thrusting plate 2 external diameter is provided with draw-in groove, and described extrapolability sheet 1 inside caliper accesses in described draw-in groove to be limited between interior thrusting plate 2 and extrapolability sheet 1 by retainer 4.
As shown in Figure 3, described interior thrusting plate 2 comprises integrated inner clip plate 21 and cylindrical first chuck 22, described first chuck 22 external diameter is provided with draw-in groove, described extrapolability sheet 1 comprises outer plate 11 and cylindrical second chuck 12, described second chuck 12 clamping enters in described draw-in groove, retainer 4 can be fixed effectively by the cooperation of the first chuck 22 and the second chuck 12.
The fore shaft 23 that described first chuck 22 external diameter end is provided with fore shaft 23, first chuck 22 that can compress the second chuck 12 can prevent the second chuck 12 from deviating from draw-in groove, thus ensure that intensity.
Compared with prior art, needle roller thrust bearing of the present invention pins extrapolability sheet 1 internal diameter by interior thrusting plate 2, fore shaft size is wide, intensity is high, fore shaft wear resistance is good, thus improve the lubricity of bearing, be conducive to storing lubricant oil, this needle roller thrust bearing is applicable to that rotating speed is higher, the operating mode of rather harsh.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
