Abstract

The present invention relates to an oilfree stainless steel rolling needle bearing which comprises a rolling shaft, a plurality of cylindrical rolling needles arranged around the rolling shaft and a shaft sleeve for sheathing the rolling needles, wherein the rolling shaft and the rolling needles are made of stainless steel, and the shaft sleeve is made of composite material which is composed of 40 to 50% of carbon fluoride, 30% of rare earth, 5% of carbon fiber and 15 to 25 % of teflon. A roller combined with the bearing can be used as a roller for bags, a roller for roller skates, etc.

Description

Oilless stainless steel needle bearing
The present invention relates to needle bearing, relate more specifically to oilless stainless steel needle bearing.
Bearing all is indispensable a kind of part in many machineries.Now the constituent element of the bearing of Shi Yonging generally with metal for example Bearing Steel make, existing shortcoming is that the part that metal is made need use lathe, grinding machine to process and Quenching Treatment, difficulty of processing is big, and complex process; Bearing easily gets rusty, corrodes in addition, needs maintenance work usually, adds oiling agent.So seeking the suitable manufactured materials of bearing constituent element is the major subjects of related domain.
The purpose of this invention is to provide a kind of oily stainless steel needle bearing that need not.
The objective of the invention is to be achieved through the following technical solutions: a kind of oilless stainless steel needle bearing, it comprises a roller bearing, all tubular needle roller that centers on this roller bearing setting and an axle sleeve that entangles all needle rollers, wherein this roller bearing and all needle rollers are made with stainless steel, this axle sleeve is made with composite material, and this composite material is made up of 40% to 50% fluorocarbons, 30% rare earth, 5% carbon fiber, 15% to 25% teflon.
The axle sleeve that above-mentioned composite material is made has the extremely low friction factor of superslide, and has reduced the rigidity requirement to roller bearing, so roller bearing and needle roller can be made with stainless steel, therefore can not get rusty according to bearing of the present invention; And because the friction between axle sleeve and the needle roller is very little, the ultrafine dust that is produced when friction plays self-lubricating function again, so do not need to add the maintenance work of oiling agent.
Below in conjunction with accompanying drawing the present invention is done detailed explanation, in the accompanying drawings:
Fig. 1 removes one to break away and to have the side view of the needle bearing of roller behind the wheel mounting.
Fig. 2 is the sectional view along Fig. 1 center line A-A.
As depicted in figs. 1 and 2, an all tubular needle roller 5 that is provided with by a roller bearing 1, around this roller bearing 1 according to needle bearing of the present invention and an axle sleeve 4 that entangles all needle rollers are formed.According to needs, can be on axle sleeve 4 a sheathed roller 3, the bearing bracket stand that has roller 3 is located on the pulley mounting 2.
This roller bearing 1 and all needle rollers 5 usefulness stainless steels are made, and these axle sleeve 4 usefulness composite materials are made, and this composite material is made up of 40% to 50% fluorocarbons, 30% rare earth, 5% carbon fiber, 15% to 25% teflon.
Be not limited to illustrated shape according to axle sleeve 4 of the present invention, its available above-mentioned composite material compacting sintering becomes multiple shape.Use the axle sleeve 4 of this composite material manufacturing to have advantages such as extremely low friction factor, high temperature resistant (300 ℃), shock resistance and plasticity are strong, and this axle sleeve 4 has reduced the rigidity requirement to roller bearing 1, in the present invention, available common 304 type stainless steels are made roller bearing 1 and needle roller 5, both reduce cost, and had rustless advantage.In addition, in this axle sleeve 4, added micron order and nano level fluorocarbons particle, so axle sleeve 4 will produce ultra-fine powder when with needle roller 5 friction taking place, and be equivalent to numerous extra small ball and roll betwixt, thereby play the effect of selflubricating, therefore exempted the work of maintaining of refueling.
The roller that combines with bearing of the present invention can be used as building doors and windows roller, case and bag roller, skating shoe roller or the like.
