Roll squeezer is when operation; Because material properties, the isoparametric influence of extruding force; Slide and beat in movable roll and bearing block thereof front and back on frame; Must adopt mechanism to adapt to the slip and the deflection of bearing block, simultaneously to the motion of bearing block carry out spacing with bear axial force, prevent to cause the damage of base bearing, base bearing sealing device and bearing cover.
Present roll squeezer is provided with feather key mechanism at movable roll bearing block middle part; Because feather key is arranged on the middle part of bearing block; Be difficult to carry out examination and maintenance after the wearing and tearing, charging scraper-trough conveyer and top feed arrangement, frame and the pipeline etc. of roll squeezer that must when overhaul, dismantle the top of roll squeezer carry out maintenance process, cause the excessive wear of feather key position; Cause the axial motion and the impact of movable roll roll shaft and bearing block, cause the too fast damage of parts such as base bearing, bearing seal and end cap.
Summary of the invention
The technical problem that the utility model will solve is that existing roll squeezer movable roll feather key swing mechanism is installed in bearing block middle part, can't check, overhauls difficulty, part life is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of feather key swing mechanism of roll squeezer movable roll bearing block, comprise feather key mechanism and sliding sash, and feather key mechanism can move in sliding sash; Said feather key mechanism comprises axle head baffle plate and the bearing pin of socket, oscillating bearing, feather key in order from the inside to surface, and oscillating bearing is positioned at the bearing pin bottom, and the axle head baffle plate is fixedly connected on the bottom of bearing pin, with the top of oscillating bearing retaining at the axle head baffle plate; Said sliding sash comprises the gripper shoe of left and right sides sidewall and front/rear end.
During installation, the top of bearing pin embeds from the bottom in the bearing block outside, and interference fit with it, makes feather key mechanism be fixed on the bottom in the bearing block outside, and sliding sash is installed in the place corresponding with the feather key mechanism position on following of the frame; During the roll squeezer operation, feather key mechanism can move in sliding sash, and feather key also can be swung around bearing pin through oscillating bearing simultaneously; The utility model compared with prior art because the feather key swing mechanism is arranged on the outside of bearing block, is conveniently installed and adjustment.
For further facilitating Unit Installation and adjustment, said left and right sides sidewall is double-decker, and the internal layer of left side wall is a wearing plate, and skin is a shim pack; The internal layer of right side wall is a wearing plate, and skin is a cover plate; Also be provided with fuel feed hole on the wearing plate of left side wall.Shim pack is mainly used in the appropriate clearance of adjusting as required between feather key and the sliding sash, and the setting of wearing plate can make feather key directly not contact cover plate and shim pack, helps the service time of extension fixture; Establish fuel feed hole on the wearing plate of madial wall, the lubricating oil on the bearing block can be flowed in the groove, reach the effect of lubricated feather key mechanism and sliding sash; When the wearing and tearing of feather key and sliding sash wearing plate maybe need be overhauled; Only need dismounting cover plate, gripper shoe and wearing plate etc.; Carry out DATA REASONING; Can realize through changing suitable shim pack and wearing plate, significantly improve the operational reliability and the life-span of equipment, reduce time between overhauls(TBO), maintenance and the maintenance cost of equipment.Above-mentioned wearing plate, shim pack, dust excluding plate, gripper shoe all adopt existing product.
As a kind of improvement project of the utility model, the bottom of sliding sash also is provided with dust excluding plate.Dust excluding plate not only can prevent the entering of dust, but also storing lubricating oil fat.
The utility model has the advantages that: simple in structure, easy installation and removal, service time grow, reduce time between overhauls(TBO), maintenance and the maintenance cost of equipment.
Description of drawings
Fig. 1 is the structural representation that the utility model is installed.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises feather key mechanism and sliding sash, and feather key mechanism can move in sliding sash; Said feather key mechanism comprises bearing pin 5, oscillating bearing 4, the feather key 3 of axle head baffle plate 6 and socket in order from the inside to surface, and oscillating bearing 4 is positioned at bearing pin 5 bottoms, and axle head baffle plate 6 is fixedly connected on the bottom of bearing pin 5, with the top of oscillating bearing 4 retainings at axle head baffle plate 6; Said sliding sash comprises left and right sides sidewall, be positioned at the dust excluding plate 11 of bottom land, be positioned at the gripper shoe 10 of groove front/rear end, and said left and right sides sidewall is double-decker, and the internal layer of left side wall is a wearing plate 8, and skin is a shim pack 12; The internal layer of right side wall is a wearing plate 8, and skin is a cover plate 7; Also be provided with fuel feed hole on the wearing plate 8 of left side wall.
The roll squeezer structure that is used with the utility model is that movable roll bearing block 1 is placed on following 2 of the frame, and following 2 of frame is fixed on the basis.
During installation, the top of bearing pin 5 snaps in from the exterior bottom of movable roll bearing block 1, both interference fit, and with bolt locking, feather key mechanism is fixedly connected with movable roll bearing block 1; Sliding sash then is installed on following 2 of the frame; Its position is corresponding with feather key mechanism; Make feather key mechanism be positioned at sliding sash; Promptly through one group of double-screw bolt 9 gripper shoe 10 and cover plate 7, wearing plate 8 and shim pack 12 are fixedly connected on following 2 of the frame, dust excluding plate 11 also is connected with following 2 of cover plate 7, gripper shoe 10 and frame through bolt; Feather key 3 can be adjusted through the pad number of adjustment shim pack 12 with the appropriate clearance of wearing plate 8; The wearing plate 8 of left side wall is provided with fuel feed hole; The oil that is flowed into by the oilhole on the movable roll bearing block 1 advances in the fuel feed hole inflow sliding sash, and in order to lubricated oscillating bearing 4, feather key 3 and wearing plate 8, dust excluding plate 11 is positioned at the bottom; Not only can prevent the entering of dust, but storing lubricating oil fat also.
