Description
Technical field
The utility model includes non-ferrous metal casting technology field, particularly one online aluminium liquid getter rigid hollow axis system.
Background technology
In Production of casting Al alloys process, the quality control of aluminium liquid is directly connected to the quality of casting quality.Wherein, at aluminium from before being melted to casting, degassing processing is carried out to aluminium liquid, reduces the hydrogen richness of aluminium liquid, be for Foundry Production provide qualified, the essential condition of high-quality Al liquid.Usually on aluminum casting production line, choice for use online aluminium liquid getter carries out last degassing processing to aluminium liquid before casting.
Existing online aluminium liquid getter rotor driving mechanism mainly contains two kinds:
External same category of device, the general reducing motor that adopts connects motor-shaft extending and stainless steel main shaft by shaft coupling, and main shaft is solid shaft.Degasification gas inputs from the spindle drum side of bearing support bottom, enters into graphite bars mechanism spray in molten aluminium by the cavity between spindle drum and main shaft.The graphite mechanism of this kind of structure upper bearing support and bottom forms supporting device jointly, and the graphite mechanism section of bottom plays graphite sliding bearing effect, can bear very high temperature.Adopt this structure, structure is simple, and running is stable, and resistance to air loss is good, but processing requirement is very high, and especially main shaft and top rotate the processing of tight mechanism and the processing of graphite bearing part, and domestic is enable processing, and also needs to expend very high cost.During sealing part abrasion, scene cannot be keeped in repair, and whole mainshaft mechanism need be returned factory's maintenance, rather time-consuming.This external replacing requires higher when installing graphite mechanism, once graphite mechanism is provided with deviation, main shaft opposite upper parts bearing support may be caused to become cantilever position, such that anterior graphite sliding bearing work is abnormal even lost efficacy.
Domestic same category of device, general employing common electric machine drives synchronous pulley to drive inside and outside two-stage hollow spindle, from the swivel joint of inner main axis upper end access inertia degasification gas (comprising chlorine), and imported in graphite bars mechanism by the centre hole of inner main axis and complete degasification operation.Outer main shaft directly connects belt wheel, forms supporting structure with bearing support, can not split out at ordinary times, is connected between inside and outside main shaft by key, can change Inner main shaft as required.In this kind of mechanism, synchronous belt pulley transmission part is weak link, and during running, vibration is comparatively large, and graphite bars beat whipping is serious, needs the long period to carry out installation and corrects.Under the high temperature with high dust environment residing for getter, synchronous pulley is in-house can pile up a large amount of dust, and transmission was lost efficacy gradually; The Timing Belt of rubber is easily aging.If width between centers adjustment is bad or when using, rotor turns encounters obstruction, enters the caking in aluminium liquid or be mingled with, usually can be disconnected by synchronously bringing into, cause degasification operation to interrupt, impact is produced.In addition, this kind of mechanism form complex structure, resistance to air loss is poor, and between inside and outside main shaft, in-site installation precision cannot ensure, very easily causes running vibration and then causes the serious beat of graphite bars.In addition, swivel joint and joint portion, main shaft top are difficult to accomplish to seal completely, add the factors such as the vibration that toothed belt transmission causes, and make it be unsuitable for using chlorine to replace rare gas element to carry out degasification operation.
Utility model content
The purpose of this utility model is to provide a kind of online aluminium liquid getter rigid hollow axis system.
In order to solve the problem, the utility model is achieved through the following technical solutions:
Online aluminium liquid getter rigid hollow axis system of the present utility model, comprise swivel joint, swivel joint interconnecting device, parallel shafts reducing motor, motor dowel disc, rolling bearing group, suspended axle bearing, graphite sliding bearing, upper water cooler, cooling connecting tube, lower water cooler, main shaft, bearing bracket, shaft coupling and graphite mechanism, main shaft is fixed on bearing bracket, the top of main shaft is connected with swivel joint by swivel joint interconnecting device, main the tip of the axis is connected with graphite mechanism by shaft coupling, main shaft is driven by parallel shafts reducing motor, the lower end of parallel shafts reducing motor is provided with motor dowel disc, rolling bearing group, graphite sliding bearing and upper water cooler are installed on the corresponding position in suspended axle bearing, and described suspended axle bearing is fixed on bearing bracket, upper water cooler is connected by cooling connecting tube with lower water cooler.
Further, described parallel shafts reducing motor is provided with locating flange, and motor dowel disc is arranged on the locating flange of parallel shafts reducing motor.
Compared with prior art, the beneficial effects of the utility model are: online aluminium liquid getter rigid hollow axis system of the present utility model, have the following advantages: one, based on the hollow spindle mechanism that Timing Belt drives, use reducing motor as power input source, and under mainshaft mechanism being closed reduce site environment dust on the impact of physical construction; Improve corresponding physical construction, make power be directly delivered to rotor, decrease intermediate torque loss, also reduce power of motor simultaneously.Two, flexible axis structure is replaced with rigid shaft structure, inside and outside main shaft is merged into single main shaft, and makes main shaft and graphite mechanism independent mutually, main shaft has oneself complete supporting device, by the supporting of graphite mechanism, installation difficulty when installing graphite mechanism need do not reduced.Three, main axle structure is designed to totally-enclosed property, accesses rare gas element as degasification source of the gas, and is carried by rare gas element gas circuit and optional chlorine gas transfer gas circuit to separate completely, strengthen security by the swivel joint of upper end.
