Abstract
The utility model relates to a structure of large-scale shaft coupling specifically is a crowned tooth shaft coupling end cover seal structure. The end cover is connected with the rear end of the inner gear sleeve, the rear end face of the end cover is provided with an annular groove, an annular floating sealing ring is arranged in the annular groove, the outer diameter of the floating sealing ring is smaller than that of the annular groove, the floating sealing ring is limited in the annular groove by a rear cover plate connected to the rear end face of the end cover, a sealing ring groove is formed in the inner hole wall of the floating sealing ring, a sealing ring is arranged between the sealing ring groove and the outer cylindrical surface of the outer gear half coupling, and end face sealing is arranged between the front end face and the rear end face of the floating sealing ring and between the annular groove and the rear cover plate. The utility model discloses when guaranteeing reliable sealing, avoided the emergence of interfering under big operating angle, the operation is reliable.
Description
Technical field
The utility model relates to a kind of structure of large-scale coupling, specifically is a kind of sealing structure of end cover of crowned tooth coupler.
Background technique
Crown gear coupling has generally included by intermeshing internal tooth casing of crowned teeth and external tooth half connection, connect end cap in the internal tooth casing rear end, usually adopt seal ring to seal between the external cylindrical surface of end cap endoporus and external tooth half connection, owing to have certain interval between the endoporus of external tooth half connection and end cap, therefore the operating angle between internal tooth casing in the working procedure and external tooth half connection carried out the compensation of certain limit.But, traditional this sealing configuration does not allow the excesssive gap between the endoporus of external tooth half connection and end cap, therefore its angular range that can compensate limited, usually can not be greater than 1.5 °, when operating angle is excessive, external tooth half will produce hard spot with end cap and contact, thereby cuts off bolt, destroys.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of work offset angle is big, the reliable sealing sealing structure of end cover of crowned tooth coupler.
Sealing structure of end cover of crowned tooth coupler of the present utility model includes by intermeshing internal tooth casing of crowned teeth and external tooth half connection, connect end cap in the internal tooth casing rear end, the end cap ear end face has an annular groove, in annular groove, be mounted with the fluctuate hermetical ring of an annular, the external diameter of fluctuate hermetical ring is less than the external diameter of annular groove, fluctuate hermetical ring is spacing in annular groove by the back shroud that is connected on the end cap ear end face, have seal groove on the inner hole wall of fluctuate hermetical ring, between the external cylindrical surface of seal groove and external tooth half connection seal ring is set, is provided with end face seal between the front/rear end of fluctuate hermetical ring and annular groove and the back shroud.
The axial section profile of the inwall of described fluctuate hermetical ring is curved.
In the sealing structure of end cover of crowned tooth coupler of the present utility model, realize and the partly sealing of connection of external tooth by fluctuate hermetical ring on the end cap, move with the change in location of external tooth half connection on the seal ring right side on the fluctuate hermetical ring, when guaranteeing reliable sealing, gap between external tooth half connection and the end cap is strengthened, avoided the generation under big operating angle, interfered, reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic representation of the A of Fig. 1.
Embodiment
As shown in Figure 1, in this sealing structure of end cover of crowned tooth coupler, internal tooth casing 1 and external tooth partly join 2 and are meshing with each other by crowned teeth, connect end cap 3 in the internal tooth casing rear end.
As shown in Figure 2, have an annular groove 4 on end cap 3 ear end faces, be mounted with the fluctuate hermetical ring 5 of an annular in annular groove, the external diameter of fluctuate hermetical ring is less than the external diameter of annular groove 4, makes fluctuate hermetical ring radial displacement within the specific limits.Fluctuate hermetical ring 5 is spacing in annular groove 4 by the back shroud 6 that is connected on end cap 3 ear end faces, have seal groove on the inner hole wall of fluctuate hermetical ring 5, between the external cylindrical surface of seal groove and external tooth half connection seal ring 7 is set, is provided with end face seal 8 between the front/rear end of fluctuate hermetical ring and annular groove and the back shroud.The axial section profile of the inwall of fluctuate hermetical ring 5 is curved, further to avoid the interfering compensation range of increase operating angle.
Claims (2)
1, a kind of sealing structure of end cover of crowned tooth coupler, include by intermeshing internal tooth casing of crowned teeth (1) and external tooth half connection (2), connect end cap (3) in the internal tooth casing rear end, it is characterized in that: end cap (3) ear end face has an annular groove (4), in annular groove, be mounted with the fluctuate hermetical ring (5) of an annular, the external diameter of fluctuate hermetical ring is less than the external diameter of annular groove, fluctuate hermetical ring (5) is spacing in annular groove by the back shroud (6) that is connected on the end cap ear end face, have seal groove on the inner hole wall of fluctuate hermetical ring (5), between the external cylindrical surface of seal groove and external tooth half connection seal ring (8) is set, is provided with end face seal between the front/rear end of fluctuate hermetical ring (5) and annular groove and the back shroud.
2, sealing structure of end cover of crowned tooth coupler according to claim 1 is characterized in that: the axial section profile of the inwall of fluctuate hermetical ring (5) is curved.
