Background technique
In conveying mechanism field, steel shaft usually can be adopted as the main shaft of the rotating machinerys such as screw conveyor, and its reliability, directly affects production process.
Current known steel shaft, normally utilizes the form of flange bolt by head, tailing axle together with fastener for connection; Or adopt head, tailing axle to insert in steel pipe to be cross-linked head, tailing axle together with fastener for connection with pin bolt again.These two kinds of structures there will be following problem in practice: (1) employing fastening piece switching performance is unreliable, and often because of the fluctuation of material medium, load increase causes steel shaft in flange connection surface or the fracture of bolt place, equipment operation was lost efficacy, produces stopping; (2) under some material medium long-term corrosion effect, the connection of fastening piece also may be lost efficacy and be made equipment operation not normal; (3) easily loosen because fastening piece connects, even if take certain locking measure, in long-term running vibration, under material friction, corrosive action, or easily loosen, affect equipment smooth operation, or drop after unclamping in following apparatus, cause device damage.
Model utility content
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art, provides a kind of steel-pipe welding axle construction, its low cost of manufacture, and transmitting torque is large, corrosion-resistant, long service life.When passing into cooling medium, can use under higher building material temperature environment, being specially adapted on the rotor shaft of carbon black industry wet granulator.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of steel-pipe welding axle construction, comprise an axle, tailing axle, steel pipe, described head axle and tailing axle are installed with large support ring and little support ring respectively, large and small support ring is welded into a whole with head axle and tailing axle respectively, described steel duct two ends arrange two sections of ladder endoporus respectively, the diameter of outer ladder endoporus is greater than interior ladder diameter of bore, head axle and tailing axle are arranged on steel pipe two ends, little support ring inserts in steel pipe in ladder endoporus by interference fit, and big bear ring inserts in the outer ladder endoporus of steel pipe by transition fit; Described large and small support ring is fixed together by the form of plug welding and steel pipe, and the solder joint of plug welding is uniform along steel pipe circumferencial direction, and quantity is more than 4 o'clock; Described large support ring end face passes through fillet welding mode and Steel pipe end surface soldering and sealing is dead, makes large and small support ring and steel pipe form an enclosed space.
Further, described head axle and tailing axle are axially drilled with axial hole, head axle residing in the enclosed space formed by size support ring and steel pipe and tailing axle radial direction are drilled with radial direction through hole, radial direction through hole is communicated with axial hole, heating or cooling medium can be passed in the axial hole of such head axle and tailing axle, use for heat temperature raising material or under higher building material temperature environment, make the utility model Applicable scope more extensive.
As preferably, the bore dia of described axial hole or radial direction through hole is 18 ~ 30mm.
As preferably, described axial hole is identical with the bore dia of radial direction through hole.
Compared with prior art, the utility model adopts the form of welding that head, tailing axle and steel pipe are connected to become entirety by support ring, there is structure simple, transmitting torque is large, stable connection, intensity are high, not easily lost efficacy, the feature of long service life, is particularly useful for the axle of carbon black industry wet granulator rotor shaft and screw conveyor; Owing to have employed intermediate support loop member, make head, tailing axle stock utilization is improved, reduce cost of material; Because steel pipe welding spindle has through through hole, other media can be introduced wherein, play the effect of cooling or heating, make the utility model Applicable scope more extensive.
