Description
Affiliated field: the plastic slide block bearing that relates to a kind of mechanical equipment coordination parts class sliding bearing classification.
Technical background: bearing is the general matching parts of machinery.There are two kinds at present: rolling bearing and sliding bearing.Rolling bearing is made up of stationary ring, rotating ring, mobile friction member and retainer.The friction member that moves is ball, roller and the needle roller of metal, and each element is stressed evenly.Because of it is point or the stressed raising that limits bearing capacity of line.Sliding bearing is contacting of axle and bearing shell face, and bearing capacity improves greatly.Axle is a revolving part, and bearing shell is a fixed block.Though oiling agent is arranged, when low speed, can not form oil film, the wearing and tearing of the stressed big position of bearing shell are just bigger, the service life shortening.So big load, the slow-speed of revolution, large-sized rotating machinery never have desirable self-contained bearing.
Plastics are one of human greatest inventions, and it has changed a lot of traditional structure and materials.The good plastics of frictional behaviour have been widely applied among the fricting couple pieces such as various bearing shells, axle sleeve.Particularly big load, low speed, large-sized slide member be like the jumbo guide rail, the shipbuilding slide unit, and large-scale hydroelectric generator bearing shell, huge floodgate sliding rail etc. have been used plastics as after the friction layer, and the Security and the life-span of operation improve greatly.This is for the invention provides technical foundation.
The problem that need to solve: the present invention is the plastic slide block bearing that big load, the slow-speed of revolution, large-sized rotating machinery provide a kind of new structure.
Summary of the invention: the plastic slide block bearing is made up of rotating ring, stationary ring, slider and oiling agent.Slider is to be lined up by many identical plastic slide blocks of shape to constitute circumference, is installed between rotating ring and the stationary ring.The shape of the plastic slide block of thrust plastic slide block bearing is fan-shaped type piece.Radially the shape of the plastic slide block of plastic slide block bearing is the circular arc type piece.Can be combined into pylon plastic slide block bearing by thrust and radial slider bearing.
The shape of the plastic slide block of independent pylon plastic slide block bearing is rectangular shape piece and fan-shaped type piece.The shape of the plastic slide block of frustum plastic slide block bearing is a cone angle type piece.Plastic slide block is to be that the plastics of main component are processed with filler modified teflon.Plastic slide block is to be that the plastics of main component are processed to gather stupid ester.The composite plastic slide block is recess-mounted structure or wire braze-welded structure.
The shape of the plastic slide block of piece bearing is rectangular shape piece and fan-shaped type piece.The shape of the plastic slide block of frustum plastic slide block bearing is an acute angle type piece.The shape of the plastic slide block of sphere plastic slide block bearing is the spherical piece.Plastic slide block is to be that the plastics of main component are processed with filler modified teflon.Plastic slide block is to be that the plastics of main component are processed to gather stupid ester.The composite plastic slide block is fluted to be inlayed and two kinds of wire solderings.
Beneficial effect: the present invention and existing technology are relatively; It has the bearing capacity of sliding bearing; The rolling bearing that kind friction member mobile along with the rotation of axle arranged again, stressed big position is moved on each plastic slide block in turn, wearing and tearing will become very slight relatively so.

Implementation methods:
One, the structure of plastic slide block bearing is 50 tons of load-bearing according to instance, 1～5 rev/min of revolution, and 6 meters of axle journals, the plastic slide block bearing that flange connects is an example, accompanying drawings is following:
The structure of example 1, thrust plastic slide block bearing is as shown in Figure 1.Thrust rotating ring 1 is a Cast Steel, internal diameter ￠ 6050mm, and the seam through ￠ 7200mm is connected with rotating machinery with flange.Its rubbing surface ￠ 6200mm～￠ 7000mm polishing, roughness Ra0.8.Thrust stationary ring 4 Cast Steels are installed on the supporting base of equipment, and plastic slide block groove and oil groove are arranged on it.Thrust plastics slider 2 is to be lined up by 120 fan-shaped plastic slide blocks to constitute circumference, is installed in the slide block slot between rotating ring and the stationary ring the fan-shaped internal diameter ￠ 6206mm arc length 162 of every plastic slide block, external diameter ￠ 6994mm arc length 183mm, centre distance 396mm.Foursquare arc R10mm.The thick 15mm of fan-shaped plastic slide block, height error is not more than 0.05mm.Envelope dirt 3 prevents the dust intrusion.
Example 2, vertical radial plastic slide block bearing structure is as shown in Figure 2.Radially rotating ring 5 is a Cast Steel, and its flange edge is connected with rotating machinery, internal diameter ￠ 6200mm, the high 200mm of external diameter rubbing surface ￠ 6500mm.Stationary ring 6 Cast Steels radially, its flange is installed on the supporting base of equipment, and internal diameter rubbing surface ￠ 6520mm and internal baffle constitute plastic slide block groove and oil groove.Radially circular arc plastics slider 7 is made up of 120 circular arc type plastic slide blocks.Every plastic slide block internal diameter ￠ 6506mm, external diameter ￠ 6814mm, thick 20 (0.50-0.65) mm, outer arc length 188mm, the height 200mm in center.
Example 3, column base type plastic slide block bearing is as shown in Figure 3, and it is that example 1 is combined with routine 2.Pylon rotating ring 8 has seam to be connected with rotating machinery with screw.It has three rubbing surfaces.Contact with right angle plastics slider 10 with thrust plastics slider 12 respectively.Pylon stationary ring 11 has pushing slide block groove, right angle plastic slide block groove and lubrication groove in the space of one.Pylon gland 9 is fixed by bolts on the pylon stationary ring 11.
Example 4, frustum type plastic slide block bearing structure is as shown in Figure 4.Frustum rotating ring 13 has taper and two rubbing surfaces of thrust.Plastics slider 15 is that 120 cone angle plastic slide blocks are formed.Stationary ring is divided into conical seat 14 and thrust bearing 18 two-part, connects through bolt 17 and oil sealing 16.
What two, the plastic friction performance was best is fluoroplastic.Simple fluoroplastic matter softer has creep properties.Add modifier such as molybdenum disulfide, gather stupid ester, aramid fibre etc. and can make moderate progress., the load-bearing of plastic slide block can adopt pure fluoroplastic manufacturing when being lower than 1.5Mpa.When the load-bearing of plastic slide block can be adopted the fluoroplastic manufacturing of molybdenum disulfide modification during greater than 1.5MPa.Can adopt during when the load-bearing of plastic slide block and to gather greater than 2.2MPa
Stupid ester modified fluoroplastic manufacturing.When the load-bearing of plastic slide block during, can adopt the fluoroplastic manufacturing of aramid fibre modification greater than 3.2MPa.Can adopt during when the load-bearing of plastic slide block and to gather the manufacturing of stupid ester plastics greater than 3.5MPa.But the static friction performance of gathering stupid ester plastics is bad, when Sliding velocity is extremely low, adopts and gathers the composite plastic manufacturing that stupid ester plastics add fluoroplastic modification.
Three, the slide block mechanical strength of pure plastics is lower, and its processing, installation, location are all inconvenient, adopt with the method for metal composite just much better.Therefore, except the slide block of pure plastics, also has the composite plastic slide block.The composite plastic slide block is fluted to be inlayed and two kinds of wire solderings.The compound thrust plastic slide block of recess-mounted is as shown in Figure 5. Plastics 19 and 21 are embedded in the groove of metallic matrix 20.
The compound plastic slide block of wire soldering is as shown in Figure 6.Wire manufactures silk and layer 22,26, and after the former powder molding sintering of plastics 22,23, wire and layer 22,26 soldering are on metallic matrix 24.
