Abstract
The utility model discloses a plastic linear bearing which is simple in structure, easy to produce, low in cost, long in service life and convenient in installation and use. The plastic linear bearing comprises a tubular retainer made of engineering plastics and is characterized in that a groove is arranged on the circumference of the inner wall of the tubular retainer, and the included angle between the tangential line of the groove and the central axis of the retainer ranges from 0 degree to 15 degrees. The bearing, with cost only one third of a traditional linear bearing, is completely made of engineering plastics, almost free of sequential machining, high in production efficiency, light in weight, long in service life, resistant to corrosion, large in powder containing capacity, small in inertia force and impact force particularly in high-speed movement and free in maintenance as the used materials have self-lubricating functions. Since an arc surface with a periphery extends outwards is arranged in the middle of the outer surface of the tubular retainer, coaxiality of a shaft and the bearing is guaranteed and the shaft and the bearing can slide relative to each other flexibly and smoothly.
Description
Technical field
The utility model relates to linear bearing, relates in particular to a kind of plastic linear bearing.
Background technique
Linear bearing is used for unlimited stroke and cylinder axis is used.It includes the retainer of making the pipe shape with metallic material existing plastic linear bearing, inwall at retainer has posted the plastics slip film, system is with the retainer parallel axes or the groove of certain angle is arranged on the inwall circumferential surface of slip film, and this groove can hold the dust that in use enters sliding pair.This linear bearing working surface is many, complex structure, and radiating effect is poor, and the appearance dust ability in the groove is little, poor corrosion resistance, product cost height.And the axle bed of requirement axle and installation linear bearing is except having good coaxality, requiring again has higher parallelism at the axle of whole stroke with axle bed, this processing and installation requirement for product is high, otherwise the area of contact that can cause friction pair reduces, resistance to motion increases, the wearing and tearing aggravation, and reduce working life.And raising processing and installation precision will increase manufacture cost.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, easy to manufacture, cost is low, long service life, plastic linear bearing easy to install and use.
In order to achieve the above object, the technological scheme of plastic linear bearing is: it includes the retainer of making the pipe shape with engineering plastics, it is characterized in that being shaped on groove on the inwall circumference of pipe shape retainer, the angle of the tangent line of described groove and retainer central axis is 0 °～15 °.
The middle part of pipe shape retainer outer surface is shaped on the arc shaped surface of circumferential evagination.
Can also be shaped on circumferential groove respectively at the two ends of described arc shaped surface, seal ring is installed in the groove.Described seal ring is the O RunddichtringO.
On the periphery of the nearly both ends of the surface of described retainer pipe, be shaped on the jump ring groove respectively.
Above-mentioned engineering plastics are meant polyoxymethylene or polyphenylene sulfide or polyether-ether-ketone or nylon 66 or nylon 46 or any middle reinforcing fiber or the solid lubricant of adding in polyoxymethylene, polyphenylene sulfide, polyether-ether-ketone, nylon 66 and nylon 46.Described reinforcing fiber is meant glass fibre.Described solid lubricant is meant teflon or molybdenum disulfide or graphite.
Plastic linear bearing according to the such scheme manufacturing, because whole linear bearing all adopts engineering plastics to make, and needs following process hardly, the efficient height of production, cost is 1/3 of a traditional line bearing, in light weight, especially inertial force and impact force are little in high-speed mobile, long service life, corrosion-resistant, it is big to hold the dust ability, and used material has self-lubricating function, and is non-maintaining.When the middle part at pipe shape retainer outer surface is shaped on the arc shaped surface of circumferential evagination, this plastic linear bearing is installed in the bearing support of tubulose endoporus, with axle generation linear relative movement the time, plastic linear bearing can deflect and self-aligning around arc shaped surface with the position of axle, play the aligning effect similar to spherical selfaligning bearing, thereby guarantee the alignment of axle and bearing, reach each other the purpose of slip flexibly.This product can be widely used in the mechanical devices such as chemical industry, medicine, instrument, instrument, Aeronautics and Astronautics, food processing.
