Abstract
The utility model discloses a be suitable for slide bearing of taking axle sleeve of abominable operating mode under liquid, it comprises pivot, bearing frame, axle bush and steel bushing, and the bearing frame includes base and gland, and the axle sleeve is installed in the pivot, and the axle bush setting is worked under base and the gland with steel bushing surface contact friction. Compared with the prior sliding bearing, the utility model has the advantages of improving the service life by 5-10 times, reducing the cost by 40-60%, reducing the maintenance workload of the equipment, avoiding the scrapping of the rotating shaft, avoiding the quenching procedure of the rotating shaft, and being widely applied to the submerged working condition equipment such as the continuous immersion-boiling auger of chemical production, the mineral processing equipment of mining machinery and the like.
Description
The utility model relates to the engineering part in the common engineering, particularly adapts to the sliding bearing of the tape spool cover of bad working environments under the liquid.
Sliding bearing is a crucial mechanical component in the mechanical engineering, is used for the rotating shaft and the axle of supporting and space, to keep them to rotate freely or to swing and bear the load that acts on the bearing.The basic structure of sliding bearing as shown in Figures 1 and 2, it is made up of rotating shaft (1), bearing support and bearing shell; Bearing support comprises base (2) and gland (5), and bearing shell comprises lower bearing (3) and top bearing shell (4); Gland is connected by double-screw bolt (6) with base, and bearing shell is arranged on and contact friction with the rotating shaft surface between base and the gland and work down; For the ease of lubricated, on gland, be provided with oil hole (7), bearing shell is provided with the oil groove (8) of distribute lubrication oil; Bearing support and gland are cylinder iron made mostly, and the material of bearing shell is non-ferrous alloy (Cuprum alloy, aluminum alloy, Babbitt etc.) or nonmetallic material (plastics, rubber, timber graphite etc.), and rotating shaft is that Fine Steel Casting iron is handled through surface hardening.
Suitable sufficient grease lubrication of the sliding bearing of this structure and dustless nominal situation then can not adapt to a large amount of thin slags that suspend in the operating mode under lubricated difficulty, high temperature and the liquid, silt particle, operating mode poisonous and the corrosivity rugged environment.Because of unlubricated, solids abrasive materials such as silt particle, dust cause abrasive wear to pulling with ditch dug with a plow of bearing shell, often have only 10% under the nominal situation even still less working life.
The purpose of this utility model is intended to overcome above deficiency and provides a kind of suiting to use under the bad working environments under liquid, avoids the sliding bearing of abrasive material heavy wear, assurance equipment long-term operation.
The purpose of this utility model reaches in the following way: add an axle sleeve in rotating shaft in addition, bearing shell be arranged between base and the gland with rotating shaft on the axle sleeve surface contact friction and works down, the detachable replacing of bearing shell and axle sleeve wearing and tearing back, scrap to avoid bearing wear, also can remove the quenching process of rotating shaft simultaneously from, simultaneously, bearing shell and axle sleeve adopt steel material and through Quenching Treatment, to improve the surface hardness of bearing shell and axle sleeve, increase the service life.
The utility model is owing to adopt as above design, can improve 5-10 times of working life, cost decline 40-60%, reduce device maintenance work amount, guarantee to produce long-term operation, and, also avoided the quenching process of scrapping and having removed from rotating shaft of rotating shaft, can be widely used in operating mode equipment under the liquid such as preparation equipment of continuous digestion screw feeder, mining machinery of Chemical Manufacture.
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described:
Accompanying drawing 1 is the structural representation of existing sliding bearing;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1;
Accompanying drawing 3 is a structural representation of the present utility model;
Accompanying drawing 4 is the B-B sectional view of accompanying drawing 3.
As shown in Figure 3 and Figure 4: the utility model is by rotating shaft (1), bearing support, bearing shell and axle sleeve (9) are formed, bearing support comprises base (2) and gland (5), bearing shell comprises lower bearing (3) and top bearing shell (4), gland is connected by double-screw bolt (6) with base, steel bushing is installed on the axle sleeve and the rotating shaft drive fit with the hot jacket method, bearing shell is arranged on and contact friction with the steel bushing surface between base and the gland and work down, bearing support and gland are cylinder iron made, steel watt and steel bushing are selected 20CrMnTi for use, nitrogencase hardening, require more than the HRC55, the fitting surface roughness is below 08 μ m, steel watt and steel bushing after heat treatment, the surface is high strength, inside has certain toughness, bearing the rotating shaft cyclic load, and can resist shock and vibration.
The permeability that the utility model makes full use of good thermal diffusivity of operating mode under the liquid and liquid (water) produces the condition of boundary lubrication and liquid and refuels the concrete condition of difficulty down, has removed tank filler sleeve and distribution of lubrication oil groove on the existing sliding bearing.
It is excellent that the utility model is applied to continuous digestion screw feeder effect, the copper alloy bearing-bush that former design is used bad working environments under liquid is 624-900 hour following working life, bearing shell and rotating shaft all wearing and tearing are scrapped, necessary every monthly repair once, change bearing shell and rotating shaft, consume big, with short production cycle, and barium liquid highly basic is poisonous, keeps in repair very difficult.After using the utility model, annually only need maintenance once, and only need change bearing shell and axle sleeve get final product, realized low consumption, production long-term operation.
