Description
Technical field
The present invention relates to mechanical transmission structure field, particularly relate to the improvement proposed for shaft coupling.
Background technology
Shaft coupling (i.e. hitch bar), is used to couple two axles (driving shaft and driven shaft) in different institutions, so that the two rotates to transmit the machine components of moment of torsion jointly.Its design requirement be broadly divided into following some: the transmission of the moment of torsion that one, need to effectively complete between driving shaft and driven shaft so that keep therebetween synchronous rotary；Two, significantly changing must not occur in the axial spacing before driving shaft and driven shaft；Three, at special dimension, it is both needed between shaft coupling and master/slave moving axis keep mechanical seal.
To this, prior art proposes many shaft couplings, representative announce on May 8th, 2013 such as State Bureau portion entitled " shaft coupling ", the document of Application No. " 201110342133.3 "；This case discloses a kind of shaft coupling common in the art, but, this case offers the drive mechanisms such as keyway on driving shaft and driven shaft, undoubtedly the most countershaft position of centre of gravity and running precision is brought strong influence.
In addition, two are required for above-mentioned design, in part high temperature process field, driving shaft and driven shaft certainly will occur that trace expands or reduces (caused by temperature decrease) at high operating temperatures, axial spacing between driving shaft and driven shaft is limited completely extremely, then shaft coupling will be made cannot to be effectively applicable to high temperature process occasion.
So, while how making hitch bar meet above-mentioned 3 designing points at the same time, both having had and do not destroyed master/slave moving axis running precision, can be effectively applicable to again high temperature process occasion becomes the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
The present invention is directed to problem above, it is proposed that a kind of Stability Analysis of Structures, mounting means are easy, labor intensity is low, have both had and have not destroyed master/slave moving axis running precision, and can be effectively applicable to again stable type hitch bar and the installation method thereof of high temperature process occasion during use.
The technical scheme is that the driving shaft for connecting concentric and driven shaft, described hitch bar includes axle sleeve one, axle sleeve two, flange ring one and flange ring two, described flange ring one be fixedly connected on described driving shaft towards one end of described driven shaft and with described driving shaft concentric, described flange ring two be fixedly connected on described driven shaft towards one end of described driving shaft and with described driven shaft concentric；

So, the mechanical seal between hitch bar and master and slave moving axis simply, is effectively completed by sealing ring one/bis-in conjunction with the back-up ring one/bis-being connected between pressure ring one/bis-and body one/bis-of above-mentioned middle swelling respectively.
For to constitutionally stable adjustment, this case is made that following adjustment to the structure of pressure ring one, two:
The internal diameter of described pressure ring 1 is more than the external diameter of described driving shaft 1, described pressure ring 1 offers, on the inner edge (herein needing to explain: this end face of pressure ring one in the form of a ring, i.e. has an inner edge and an outer rim) of the end face of described body 1, the conical surface one being gradually reduced shape in ecto-entad internal diameter；
The internal diameter of described pressure ring 2 43 is more than the external diameter of described driven shaft 2, described pressure ring 2 43 offers, on the inner edge (herein needing to explain: this end face of pressure ring two in the form of a ring, i.e. has an inner edge and an outer rim) of the end face of described body 2 41, the conical surface 2 430 being gradually reduced shape in ecto-entad internal diameter.
If detachably connected by bolt stem 1 between described flange ring 1 and described body 1, the both sides end face of described flange ring 1 is equipped with the some packing rings 1 being socketed on some described bolts 1；(for mapping specification, neatly considering, the Figure of description of this case illustrate only the packing ring one of wherein side)
If detachably connected by bolt stem 2 61 between described flange ring 26 and described body 2 41, the both sides end face of described flange ring 2 41 is equipped with the some packing rings 2 62 being socketed on some described bolts 2 61.(for mapping specification, neatly considering, the Figure of description of this case illustrate only the packing ring two of wherein side)
Thus give in high temperature process occasion and leave enough " axial displacement " that expand with heat and contract with cold between master and slave moving axis, there is good stability, the feature of length in service life.
Described back-up ring 1, back-up ring 2 33, sealing ring 1, sealing ring 2 44, packing ring 1 and packing ring 2 62 all use organosilicone elastic material to make.About above-mentioned organosilicone elastic material, quote free Chen Xun army, " progress of Study of High Temperature Resistant Organosilicone Elastomers " that Cui Yingde, Yin Guoqiang, Li Xinming, Liao Liewen write, even if so that back-up ring one, back-up ring two, sealing ring one, sealing ring two, packing ring one and packing ring two in this case the most also can effectively work, have and use the feature in stable condition, using effect is good.
The mounting means of this case is simple, convenient, and labor intensity during installation is low, accurate positioning, and specifically, this case is installed according to the following steps:
1), mounting flange ring one and axle sleeve one:
1.1) as it is shown on figure 3, be inserted in pressure ring one, back-up ring one and sealing ring one on driving shaft successively；
1.2), as shown in Figure 4, body one is screwed in along sealing ring one；
1.3) as it is shown in figure 5, be inserted in flange ring one on driving shaft, and the connection between flange ring one and driving shaft is completed；
