Abstract
The utility model discloses a novel main transmission shaft of a chain-conveyer furnace. The main transmission shaft comprises a transmission shaft body and a barrel, wherein the barrel and the transmission shaft body are in interference fit and are welded and assembled into a whole; bosses are arranged at two ends of the barrel; pin holes are formed in the bosses; positioning pins are filled into the pin holes; the positioning pins penetrate through the barrel and enter the transmission shaft in the radial direction. The main transmission shaft has the advantages that the problem that the welding part of the transmission shaft and the barrel is broken in the use process is solved, and the strength of the main transmission shaft of the chain-conveyer furnace is improved.
Description
Technical field
The utility model relate to a kind ofly quench, tempering chain-conveyer furnace main drive shaft.
Background technique
Existing chain-conveyer furnace main drive shaft all adopts 1Cr18Ni9Ti or 1Cr18Vi9 trade mark material to make conventionally, shape and structure are as shown in Figure 1, comprise transmission shaft 1 and toothed rotor 2, because toothed rotor 2 boundary dimension are large, profile is peculiar, all adopt casting, after conventionally toothed rotor 2 and two ends transmission shaft 1 being machined separately by shape shown in Fig. 1 and structure, then the two is welded together.Existing this chain-conveyer furnace main drive shaft is due to following structure and welding procedure, and therefore in use weld 3 easily ruptures:
(1) toothed rotor in when casting because workpiece is bigger than normal, peculiarly shaped, cannot use centrifuge casting, cause workpiece cast metal particle inhomogeneous and have a pore;
(2) the welding electrode trade mark does not mate;
(3) welding procedure is improper, under normal temperature state, welds;
(4) after welding, butt welding mouth does not adopt special processing;
(5) two workpiece joints places transmit by welding entirely, and weld bond chamfering is little in addition, postwelding reprocessing, and remaining amount is not thick.
Model utility content
The utility model has overcome shortcoming of the prior art, and a kind of novel chain-conveyer furnace main drive shaft is provided.
The technical solution of the utility model is: a kind of novel chain-conveyer furnace main drive shaft, comprise transmission shaft and cylinder, and described cylinder and transmission shaft adopt interference fit and assemble welding to be integral; At cylinder two ends, be provided with concave station, at concave station, place offers pin-and-hole, is injected with locating stud in pin-and-hole, and locating stud passes rotary drum radial to entering transmission shaft.
The degree of depth that described locating stud enters transmission shaft is 12 ~ 15mm.
Described locating stud sinks to 5mm under pin-and-hole aperture.
Described locating stud and cylinder assemble welding are integral.
Described cylinder two ends and two transmission shaft joint mouth weld bond chamferings are 7 * 30 °.
Compared with prior art, the utility model has the advantages that: can eliminate in use at the breakage problem of transmission shaft and cylinder weld, increase the intensity of chain-conveyer furnace main drive shaft.Concrete manifestation is as follows:
(1) adopt argon arc welding protection effective, alloy transition rate is high, and composition of weld line is even, and stable;
(2) butt welding mouth adopts special processing when welding, comprises increasing weld bond chamfering, adopting the jointing place of multilayer welding, every layer of weld seam to stagger etc.;
(3) cylinder and shaft adapter place carry out transmitting torque by locating stud.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of existing chain-conveyer furnace main drive shaft;
Fig. 2 is the structural representation of chain-conveyer furnace main drive shaft of the present utility model;
Fig. 3 is the structural representation of chain-conveyer furnace main drive shaft component part transmission shaft 1 of the present utility model;
Fig. 4 is the structural representation of chain-conveyer furnace main drive shaft component part locating stud 2 of the present utility model;
Fig. 5 is the structural representation of chain-conveyer furnace main drive shaft component part cylinder 3 of the present utility model.
Embodiment
A kind of novel chain-conveyer furnace main drive shaft, as shown in Figures 2 to 5, comprise transmission shaft 1, locating stud 2 and cylinder 3 etc., wherein: at cylinder 3 two ends, be processed with concave station 4, cylinder 3 and transmission shaft 1 adopt interference fit, increase cylinder two ends and diaxon joint mouth weld bond chamfering (changing 7 * 30 ° into by 2 * 45 ° of original chamferings), thereby make to also have enough welding capacity after welding machine processing, guarantee cylinder and two transmission shaft weld weld strengths; After cylinder and two transmission shafts assembling welding, at concave station 4 places at cylinder 3 two ends, radially offer pin-and-hole, in pin-and-hole, inject locating stud 2.In order not affect the intensity of axle, the radial depth that locating stud 2 enters transmission shaft 1 through cylinder 3 is 12 ~ 15mm, locating stud need sink to 5mm left and right under pin-and-hole aperture, then in outside, locating stud 3 and cylinder 2 is welded, and reaches the join strength that increases cylinder and two propeller shaft couplings places; Pin can not run through transmission shaft 1, prevents from reducing the intensity of axle.
Claims (5)
1. a novel chain-conveyer furnace main drive shaft, comprises transmission shaft and cylinder, and described cylinder and transmission shaft adopt interference fit and assemble welding to be integral; It is characterized in that: at cylinder two ends, be provided with concave station, place offers pin-and-hole at concave station, be injected with locating stud in pin-and-hole, locating stud passes rotary drum radial to entering transmission shaft.
2. a kind of novel chain-conveyer furnace main drive shaft according to claim 1, is characterized in that: the degree of depth that described locating stud enters transmission shaft is 12 ~ 15mm.
