Abstract
The utility model relates to a duplex-bearing floating seal device which is composed of bearings, a framework oil seal, a bearing support and the like. According to the utility model, a sleeve is sleeved on a mixer shaft; the sleeve is sleeved with a floating seal and a bearing A sequentially; the floating seal and the bearing A are respectively sleeved with a sleeve gasket and a floating seal seat; a seal support is arranged on the outer surfaces of the sleeve gasket and the floating seal seat; an oil through threaded hole is formed on the seal support; the bearing support is arranged on the right side of the mixer shaft and provided with an oil through threaded hole, and an unframed oil seal and a bearing B are sequentially arranged in an inner cavity; a bearing contact surface of the mixer shaft is communicated with an adapter of an oil supply system, and the floating seal device is full of required lubricating oil, thereby serving the functions of lubrication, cooling, and floating seal, avoiding bearing breakage and mixer shaft locking, prolonging the service lives of the mixer shaft and the bearings, reducing cost and improving economic benefit.
Description
Technical field: the utility model relates to a kind of multi-functional forced concrete mixer, particularly relates to a kind of double-bearing floating sealing device on the stirring shaft in the concrete mixer.
Background technique; Present concrete mixer generally is not provided with the seal arrangement of seal arrangement or setting on the bearing at stirring shaft two ends, because structural design is reasonable inadequately, work under bad environment, bearing is still often damaged, axle is stuck, and causes manufacturing efficiency low, and energy consumption is big, noise is big, the situation that working life is short.
Summary of the invention; The purpose of this utility model will provide a kind of double-bearing floating sealing device exactly, it can overcome the existing problem of present concrete mixer well, the purpose of this utility model is to realize like this, a kind of double-bearing floating sealing device is made up of bearing, outside framework oil seal, bearing support, supported flange, it is characterized in that; Be with sleeve on the stirring shaft, be with floating seal, bearing A on the sleeve successively, be with stuffing box gland, floating sealing base respectively on floating seal, the bearing A, on the cylindrical of floating sealing base, be with the O RunddichtringO, be provided with holddown spring with bearing A touching position, bearing A right-hand member is provided with back-up ring, and is located on stirring shaft by jump ring; The outer surface of stuffing box gland, floating sealing base is provided with sealed support, sealed support is provided with logical whelk pit, sealed support left end screw passes supported flange, sealing gasket connects with sealed support, be provided with outside framework oil seal in the right-hand member gland groove, and pass gland by screw and connect with sealed support, sealed support by screw on round flange; The right at stirring shaft is provided with bearing support, bearing support is provided with logical whelk pit, inner chamber is disposed with exoskeletal oil sealing, bearing B, the bearing support right-hand member is provided with gland, be provided with outside framework oil seal in the gland groove, and pass gland by screw and connect with bearing support, bearing support by screw on square flange.The utility model stirring shaft supporting surface of contact communicates with the oil supply system joint, be full of required lubricant oil in the floating seal, play the effect of lubricated, cooling, floating seal, avoided breakage, stirring shaft stuck of bearing, prolonged working life of stirring shaft, bearing.Reduce cost, improved economic benefit.
Description of drawings: Fig. 1 is the utility model structural representation;
1. stirring shaft, 2. main frame riser, 3. round flange, 4. sealed support, 5.O RunddichtringO, 6. bearing support, 7. square flange, 8. bearing B, 9. gland, 10. outside framework oil seal, 11. exoskeletal oil sealings, 12. jump rings, 13. back-up ring, 14. bearing A, 15.O RunddichtringO, 16. holddown springs, 17. floating sealing base, 19. floating seals, 20. stuffing box glands, 21. sealing gasket, 22. supported flanges, 23. sleeves.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of double-bearing floating sealing device is made up of bearing B8, outside framework oil seal 10, bearing support 6, supported flange 22, it is characterized in that; Be with sleeve 23 on the stirring shaft, be with floating seal 19, bearing A14 on the sleeve 23 successively, be with stuffing box gland 20, floating sealing base 17 on floating seal 19, the bearing A14 respectively, on the cylindrical of floating sealing base 17, be with O RunddichtringO 15, be provided with holddown spring 16 with bearing A14 touching position, bearing A14 right-hand member is provided with back-up ring 13, and is located on stirring shaft by jump ring 12; The outer surface of stuffing box gland 20, floating sealing base 17 is provided with sealed support 4, sealed support 4 is provided with logical whelk pit, sealed support 4 left end screws pass supported flange 22, sealing gasket 21 connects with sealed support 4, be provided with outside framework oil seal in the right-hand member gland groove, and pass gland by screw and connect with sealed support 4, sealed support 4 by screw on round flange 3; Be provided with bearing support 6 on the right of stirring shaft, bearing support 6 is provided with logical whelk pit, inner chamber is disposed with exoskeletal oil sealing 11, bearing B8, bearing support 6 right-hand members are provided with gland 9, be provided with outside framework oil seal 10 in gland 9 grooves, and pass gland 9 by screw and connect with bearing support 6, bearing support 6 by screw on square flange 7.During concrete enforcement, casting supported flange, sleeve, stuffing box gland, floating sealing base, sealed support, round flange, bearing support, square flange, back-up ring and gland also carry out cutting by drawing; Purchase bearing, outside framework oil seal, exoskeletal oil sealing, floating seal, O RunddichtringO and jump ring.Install by Fig. 1 again, will lead to whelk pit and oil pipe everywhere and connect.After connecting power supply, open the respective switch on the control box panel, stirrer, oil pump start, the logical oil of oil pipe, because stirring shaft supporting surface of contact communicates with the oil supply system joint, floating seal is made up of fluctuate hermetical ring, floating sealing circle, if fluctuate hermetical ring inner ring and stirring shaft are too tight, stirring shaft easily is stuck, fluctuate hermetical ring inner ring and stirring shaft too pine do not have seal action again, so by lubricant oil fluctuate hermetical ring is floated, will float the sealing snare and on fluctuate hermetical ring, control it and cross loose phenomenon.The temperature rise control of floating seal and stirring shaft supporting is below 40 ℃, be full of required lubricant oil in the floating seal, play the effect of lubricated, cooling, floating seal, avoided breakage, stirring shaft stuck of bearing, prolonged working life of stirring shaft, bearing.
