Compared with prior art, the utility model arranges sealed department, and the end of sealed department is provided with flanging, easily installs and can be sealed to good sealing effect on sidewall during installation; The end of circular arc part is concordant with sealed department, and seal length increases, and sealing effect is strengthened; The cross section that circular arc part is set is circular arc, and sealed department is all delivered to circular arc part with the energy of deformation that holds out against end, and the distortion of support is delivered to circular arc part, and little with the impact that holds out against end on sealed department, sealing effect is better; Increased the length of line part, seal length strengthens, and with boss, coordinates, and has effectively strengthened sealing effect.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
In figure, 10, support; 11, boss; 12, line part; 13, circular arc part; 14, sealed department; 15, flanging; 16, hold out against end.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
A kind of seal arrangement, comprise the rotating seat, rotating ring, stationary ring and the stationary seat that are arranged in rotating shaft, rotating ring is arranged on rotating seat, stationary ring is arranged on stationary seat, support 10 is also installed between stationary ring and stationary seat, in support 10, spring is installed, the two ends of spring are resisted against on stationary ring and stationary seat by support 10 respectively, and support 10 promotes stationary ring and pushes against rotating ring.
As depicted in figs. 1 and 2, support 10 is thin wall shape ringwise, comprise sealed department 14, circular arc part 13 holds 16 with holding out against, sealed department 14 is ring, the internal circle of sealed department 14 be connected with one end of circular arc part 13 and the end of circular arc part 13 concordant with sealed department 14, increase the area of contact of sealed department 14, in outer circumferential edge, be provided with flanging 15, flanging 15 is 90 degree with the angle of sealed department 14, setting up of flanging 15 can make support 10 and the surface of contact of stationary seat strengthen, spring is also difficult for deviating from simultaneously, the shape matching with flanging 15 can be arranged in the bottom of stationary seat, strengthened sealability, the cross section of circular arc part 13 is away from axis around two sections of circular arcs of axis centre symmetry and the center of circle, the thickness of circular arc part 13 is greater than the thickness of sealed department 14, circular arc part 13 and the size of the intersection circular arc part 13 of sealed department 14 diminish gradually, and to transit to the end of sealed department 14 and circular arc part 13 concordant with the side of sealed department 14, the thickness of sealed department 14 is little, the thickness of circular arc part 13 is large, spring is pushed against on sealed department 14, can make sealed department 14 be adjacent on stationary seat, circular arc part 13 can make the distortion of support 10 concentrate on the top of circular arc, reduce the distortion of other parts, make to be out of shape controlled.
Hold out against the boss 11 that end is provided with line part 12 on 16 and is arranged on line part 12 one end, the external diameter of boss 11 is less than the external diameter of flanging 15,11 one-tenth an angle of 90 degrees of line part 12 and boss, the length of line part 12 is greater than the height of boss 11, thereby the seal distance of being longer than boss 11 in the seal distance at line part 12 places, good sealing effect, intersect to line part 12 1 sides the end of circular arc part 13, the end edge of circular arc part 13 is concordant with the end face of line part 12, during deformation of timbering, strain concentrates on circular arc part 13, can not affect whole sealing effect.
