Detailed description of the invention
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from interest field of the present invention, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the present invention.
The mine excavator of the embodiment of the present invention, has the pushing gear device of the embodiment of the present invention, and the pushing gear device of the embodiment of the present invention can be used in mine excavator.The mine excavator of the embodiment of the present invention is such as mining forward shovel etc.
Below the mine excavator of the embodiment of the present invention and the pushing gear device of the embodiment of the present invention is specifically introduced.
As shown in Figure 1, the pushing gear device of the embodiment of the present invention, for large-scale mine forward shovel, described pushing gear device comprises pushing gear 1, raceway 2, baffle plate 3 and screw 4.
As shown in Figure 1, the pushing gear device of the embodiment of the present invention, tooth bar engaged transmission below its pushing gear 1 and dipper 5, raceway on dipper 5 contacts with the raceway 2 of pushing gear device, promote dipper 5 to move back and forth in saddle, make the scraper bowl of the mine excavator of the embodiment of the present invention be accomplished excavation and tripping action.
As shown in Figure 1, raceway 2 is two, is sheathed on pushing gear 1 both sides respectively, and, as shown in Figure 2, pushing gear 1 is less than pushing gear 1 root 13 diameter B, i.e. A<B with the fitting face diameter A of raceway 2 endoporus, like this, be conducive to the processing of profile of tooth, easily ensure machining accuracy.
And baffle plate 3 is also two, as shown in Figure 5, baffle plate 3 is annulars that center has the first circular hole 30, therefore also can become baffle ring.Baffle plate 3 is sheathed on pushing gear 1 respectively, and is positioned at outside raceway 2, moves laterally to prevent raceway 2.Be interference fit between raceway 2 and pushing gear 1, and between baffle plate 3 and pushing gear 1, be matched in clearance.
As shown in Figure 1, in the present embodiment, screw 4 is fixtures baffle plate 3 being fixed on pushing gear 1.
As shown in Figures 2 and 3, the profile of tooth of pushing gear 1 is involute Cylinder Gear, and the endoporus of pushing gear 1 has internal spline 11.For the ease of the location of baffle plate 3, the both sides of pushing gear 1 have seam 15, in order to baffle plate 3 is fixed on pushing gear 1, the certain radius place of baffle plate 3 offers the countersunk 31 for wearing screw 4, in the corresponding position of pushing gear 1 both sides end face, also offer screwed hole 14, be connected with pushing gear 1 by screw 4, ensure that raceway 2 can not outwards movement.In addition, pushing gear 1 outer face, baffle plate 3 outer face are concordant with screw 4 outer face.
As shown in Figure 4, raceway 2 center also has the second circular hole 20, and 21 has certain taper inside raceway 2, and this tapering is consistent with pushing gear 1 profile of tooth side tapering.
The pushing gear device of the embodiment of the present invention, ensure that the machining accuracy of the pushing gear device of large-sized mining dredger, and processing is simple, raceway 2 serious wear is replaceable, extend the bulk life time of pushing gear device, installation, convenient disassembly, improve the economic benefit of large excavator.
Although with reference to exemplary embodiment describing the application, should be appreciated that term used illustrates and exemplary and nonrestrictive term.Spirit or the essence of invention is not departed from because the application can specifically implement in a variety of forms, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalency range and remodeling and all should be claim of enclosing and contained.
