Abstract
The utility model relates to a flexible sliding bearing, solving the problems that the sliding bearing made of metal materials is easy to wear and short in life-span. The flexible sliding bearing comprises three layers, wherein, the outer side of the utility model is a skeleton layer; the middle part of the utility model is a combined layer; the inner side of the utility model is a working layer; the skeleton layer is rubber or plastic; the combined layer is a knitted layer of polyester fiber and polytetrafluoroethylene fiber; the working layer is a knitted layer of polytetrafluoroethylene fiber. The flexible sliding bearing has a very wide temperature range for using and working, can be used for long time in the environment from 100 DEG C below zero to 150 DEG C by using different working skeletons, and can be manufactured into the sliding bearings with various specification sizes from 3 mm to 1200 mm in diameter through adjusting knitting technics.
Description
Technical field
The utility model relates to a kind of sliding bearing.
Background technique
Traditional sliding bearing is metallic material and makes, or be pure teflon press face, sliding bearing self serious wear not only in the use, wearing and tearing to axle are also very serious, working life is short, the noise that can occur various abnormal sounds after sliding bearing and the axle wearing and tearing, particularly traditional bearing or axle are prone to and break and cause mechanical failure when low-speed heave-load, even threaten personnel's life safety.
Summary of the invention
The purpose of this utility model is: the Flexible Sliding bearing that uses when low-speed heave-load of being particularly suitable for that a kind of wear-resistant, long service life is provided.
This Flexible Sliding bearing comprises the tubulose sliding bearing.The tube wall of described tubulose sliding bearing comprises three layers, and its outside is the rubber and plastic framework layer, and the middle part is a binder course, and the inboard is a working lining; Described binder course is polyster fibre and teflon fibre braided layer; Described working lining is teflon fibre braided layer.
Polytetrafluoroethylene fiber has following good characteristic: 327 ℃ of fusing points, operating temperature can reach-200 ℃-250 ℃: chemical stability is splendid, anti-strong acid, highly basic and strong oxidizer; Lubricity is good especially, and friction factor is 0.01～0.05, is minimum in the existing synthetic fiber; Limited oxygen index is 90～95%, difficult combustion under hyperoxia concentration, UL94-V0 level.And 260 ℃ of polyster fibre fusing points, 240 ℃ of softening points; Heat-resisting, fast light, acid resistant alkali, wear-resisting.Therefore this Flexible Sliding bearing has very wide use operating temperature range.Use different work skeletons in-100 ℃ of-150 ℃ of environment, to use for a long time.
Adjust weaving, can make the sliding bearing or the liner of all size size of 3 millimeters to 1200 millimeters of diameters.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
The Flexible Sliding bearing is the tubulose sliding bearing.The tube wall of tubulose sliding bearing comprises three layers, and its outside is a framework layer 1, and framework layer 1 material is rubber or plastics; The middle part is a binder course 2, and binder course 2 is terylene PET fiber and teflon fibre braided layer; The inboard is a working lining 3, and working lining 3 is teflon fibre braided layer, sees Fig. 1.
Two kinds of fibers are respectively on the inside and outside two sides of pipe, and terylene PET layer of fibers is at outer surface, and the polytetrafluoroethylene PTFE layer of fibers is at internal surface, and woollen yarn knitting is together closely between two-layer.
Terylene PET face and rubber (plastics) carry out hot vulcanization (hot melt with) is in the same place, and becomes the skeleton of sliding bearing, plays and supports and damping effect; The polytetrafluoroethylene PTFE face is the working surface of bearing, because the polytetrafluoroethylene PTFE fiber has the very little coefficient of sliding friction, self is all very little with the wearing and tearing of axle under the situation of low speed or heavy duty, the working life that can reduce noise and effectively improve product.
