For object, technological scheme and advantage that the utility model is implemented are clearer, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Described embodiment is the utility model part embodiment, rather than whole embodiments.Below by the embodiment who is described with reference to the drawings, be exemplary, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
According to S valve assembly of the present utility model, comprise S valve body and live axle, described S valve body is connected to described live axle unitary rotation thereupon removably.The S valve body of above-mentioned S valve assembly is connected with removably with live axle, when one of S valve body or live axle damage, can dismantle easily and change S valve body or live axle, reduce the needed time of changing S valve body or live axle, reduce labor intensity and save material, and this kind of S valve assembly is simple in structure, connect reliable.
Fig. 1 looks schematic diagram according to the master of the utility model one embodiment's S valve assembly.Fig. 2 is the schematic top plan view of the valve assembly of S shown in Fig. 1.Fig. 3 is the partial schematic diagram of the live axle in the valve assembly of S shown in Fig. 1.
In the embodiment shown in fig. 1, S valve assembly comprises S valve body 2 and live axle 1.S valve body 2 is connected to live axle 1 removably, and with live axle 1 unitary rotation.Advantageously, S valve body 2 is connected with live axle 1 removably, has solved 1 wearing and tearing of S valve body 2 or live axle and need to change whole S valve assembly, needs the time long, and labor intensity is large, the difficult problem that cost of material is high.
In illustrated embodiment, between S valve body 2 and live axle 1, by bearing pin 3, be connected, for limiting motion to axial and the relative circumferential movement between S valve body 2 and live axle 1.Advantageously, when S valve body 2 wearing and tearing, only bearing pin 3 need be removed, i.e. replaceable S valve body 2, and need not change live axle 1.In the manufacture of S valve assembly, due to requirements such as the material of live axle 1 and machining accuracies, cause the cost of live axle 1 very high, so just reduce to a great extent the cost of material.In addition, while changing S valve body 2, only need remove bearing pin 3, need not remove live axle 1, simplify and more change jobs, reduce and change S valve body 2 needed times and labor intensity., when live axle 1 wearing and tearing, only bearing pin 3 need be removed, i.e. meanwhile replaceable live axle 1, and need not change S valve body 2, effectively reduce cost of material and replacing time.Certainly; be understandable that; the embodiment who is connected by other removablies between S valve body 2 and live axle 1 also in the protection domain of this patent, for example, tightens together by threaded piece, or adopts flat key or spline structure to interconnect and transferring rotational motion.
In the embodiment shown in fig. 3, live axle 1 with arc groove 5, is also provided with the arc groove corresponding with arc groove 5 on live axle 1 in periphery on S valve body 2, is conducive to live axle 1 and S valve body 2 and realizes and better coordinating with bearing pin 3.More advantageously, arc groove 5 is half slot.
Be understandable that, bearing pin 3 adopts similar bolt form, one end at bearing pin 3 is provided with boss, a side for fixed pin shaft 3, the other end of bearing pin 3 is provided with screw thread, for coordinating with nut, make the opposite side of bearing pin 3 also fixing, thereby prevent that bearing pin 3 from splitting away off from S valve body 2 and live axle 1.
In the embodiment shown in Figure 2; with the nut of screw-thread fit on bearing pin 3 be double nut 4; effectively prevent bearing pin 3 from becoming flexible and bearing pin 3 is come off from S valve body 2 and live axle 1; be understandable that, thus with the nut of screw-thread fit be self-locking nut, inserts locking nut or other can with bearing pin 3 on screw-thread fit realize fastening locking functions part also in the protection domain of this patent.
In another embodiment, one end of bearing pin 3 is provided with boss, and for a side of fixed pin shaft 3, the other end of bearing pin 3 is provided with through hole, and the axis of through hole is perpendicular to the axis of bearing pin 3, for coordinating with cotter pin.Cotter pin is inserted in the through hole on bearing pin 3, thereby the opposite side that makes bearing pin 3 is also fixing, prevent that bearing pin 3 from coming off from S valve body 2 and live axle 1.Be understandable that, other parts be set on bearing pin 3 and bearing pin 3 be fixed between S valve body 2 and live axle 1 and prevent that embodiment that bearing pin 3 comes off from S valve body 2 and live axle 1 is also in the protection domain at this patent.
The quantity of bearing pin 3 can be according to the length setting of live axle 1, and the quantity of bearing pin 3 is along with the length of live axle 1 increases and increases, and the length of live axle 1 is longer, and the quantity of bearing pin 3 is more.For example the quantity of bearing pin 3 is 3,4,5 or more.The quantity of bearing pin 3 is preferably 2, and bearing pin 3 is arranged in parallel.
