Abstract
The utility model discloses a butterfly vave of flue gas turbine's bearing and valve shaft's mounting structure, it includes bearing (1), valve shaft (2) and grease add device (3), the landing leg setting that keeps off lid (5) is downthehole greatly step hole (4), big downthehole be provided with spacer ring (6) and support ring (7) of step hole (4), valve shaft (2) set up in step hole (4), spacer ring (6) and support ring (7) are all overlapped on valve shaft (2), support ring (7) set up the bottom in step hole (4), between support ring (7) and spacer ring (6), all loaded between the landing leg of spacer ring (6) and fender lid (5) filler (8), the grease adds device (3) and sets up on the outer wall of bearing (1), the grease adds the fat mouth and ring channel (9) intercommunication of device (3). The beneficial effects of the utility model are that: compact structure, extend bearing life, prevent that the grease from leaking outward.
Description
Technical field
The utility model relates to a kind of bearing of cigarette machine butterfly valve and the mounting structure of valve shaft.
Background technique
Cigarette machine butterfly valve is made up of valve body, valve shaft, the bearing being arranged on valve body two ends and valve plate, the axle journal at valve shaft two ends is arranged in two bearings respectively, valve shaft is provided with valve plate, and valve plate is arranged in valve body, and valve plate is used for cutting off or conducting liquid medium, valve shaft adopts grease lubrication, when grease lacks in bearing, need workman to dismantle bearing and valve shaft, then inject grease in bearing, such workload is very large, and complicated operation.In addition, the mounting structure of existing valve shaft and bearing is poorly sealed close, and dust easily enters in bearing, and reduce the working life of bearing, in addition, grease also can leak outside.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of compact structure, extends bearing working life, the bearing of cigarette machine butterfly valve preventing grease from leaking outside and the mounting structure of valve shaft.
The purpose of this utility model is achieved through the following technical solutions: a kind of bearing of cigarette machine butterfly valve and the mounting structure of valve shaft, it comprises bearing, valve shaft and grease adding apparatus, described bearing end is provided with step hole and door, the supporting leg of door is arranged in the macropore of step hole, spacer ring and support ring is provided with in the macropore of step hole, described valve shaft is arranged in step hole, spacer ring and support ring are all enclosed within valve shaft, support ring is arranged on the bottom of step hole, between support ring and spacer ring, all filler is filled with between spacer ring and the supporting leg of door, the cylinder of described spacer ring is provided with circular groove, described grease adding apparatus is arranged on the outer wall of bearing, the grease outlet of grease adding apparatus is communicated with circular groove.
Described spacer ring is arranged on the middle part of the macropore of step hole.
The utility model has the following advantages: (1) the utility model support ring is arranged on the bottom of step hole, all filler is filled with between support ring and spacer ring, between spacer ring and the supporting leg of door, effectively prevent extraneous dust and enter the phenomenon occurring stuck bearing in bearing, extend the working life of bearing, meanwhile, filler can also effectively prevent the grease in bearing from revealing.(2) grease adding apparatus is arranged on the outer wall of bearing, and the grease outlet of grease adding apparatus is communicated with circular groove, therefore facilitates injection grease, simple to operate, laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I portion partial enlarged view in Fig. 1;
In figure, 1-bearing, 2-valve shaft, 3-grease adding apparatus, 4-step hole, 5-door, 6-spacer ring, 7-support ring, 8-filler, 9-circular groove.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of bearing of cigarette machine butterfly valve and the mounting structure of valve shaft, it comprises bearing 1, valve shaft 2 and grease adding apparatus 3, and described bearing 1 end is provided with step hole 4 and door 5, and the supporting leg of door 5 is arranged in the macropore of step hole 4.As depicted in figs. 1 and 2, spacer ring 6 and support ring 7 is provided with in the macropore of step hole 4, described valve shaft 2 is arranged in step hole 4, spacer ring 6 and support ring 7 are all enclosed within valve shaft 2, support ring 7 is arranged on the bottom of step hole 4, filler 8 is all filled with between support ring 7 and spacer ring 6, between spacer ring 6 and the supporting leg of door 5, filler 8 effectively prevent extraneous dust and enters the phenomenon occurring stuck bearing in bearing 1, extend the working life of bearing, meanwhile, filler 8 can also effectively prevent the grease in bearing 1 from revealing.The cylinder of described spacer ring 6 is provided with circular groove 9.As depicted in figs. 1 and 2, grease adding apparatus 3 is arranged on the outer wall of bearing 1, the grease outlet of grease adding apparatus 3 is communicated with circular groove 9, after in bearing 1, grease runs out of, only need add grease in grease adding apparatus 3, grease reaches on valve shaft 2 through circular groove 9, to be lubricated by valve shaft 2, has stuffing feature easily and fast.
Described spacer ring 6 is arranged on the middle part of the macropore of step hole 4.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
