Abstract
The utility model relates to a combination type sealing member used on a motion axis, which comprises a support ring, a clamping ring and a row of sealing rings, wherein a fracture is respectively arranged on the sealing rings, the contiguous fractures are alternately arranged, and the longitudinal cross section of each sealing ring is in an inversed V shape; the upper ring surface of the support ring and the lower ring surface of the clamping ring are provided with a V-shaped convex ring and a V-shaped concave ring which are buckled with the inversed V shape, and the support ring and the clamping ring are respectively composed of two bodies fifty-fifty. The utility model has the advantages of stable and reliable operation, good sealing effect and long service life.
Description
Technical field the utility model relates to employed a kind of combination seal on the travel axis.
Background technique is present, the Sealing that on travel axis, is equipped with, generally all be to adopt seal ring or with modes such as filler compress, to prevent that medium from leaking from the gap of travel axis, obtain effective seal, and this kind seal ring all is the enclosed ring structure, when travel axis in seal ring or filler, rotate or on, under when moving, friction causes the gap to increase for a long time, medium leaks easily, working life is short, when changing Sealing, trouble is just bigger, and it must be torn the termination of travel axis open and expose, can change Sealing, for the travel axis of dismounting difficulty, must realize changing and install by supplementary equipment, so not only time-consuming, effort has also been brought the certain economic loss to production.
The summary of the invention the purpose of this utility model provides that a kind of use is reliable, the life-span is long, is convenient to a kind of combination seal of installing/dismounting.
The utility model is achieved in that a kind of combination seal, comprise support ring, pressure ring and row's seal ring, it is characterized in that: have a fracture on the seal ring, adjacent interruptions is staggered, the longitudinal cross-section of seal ring is the font of falling V, the following anchor ring of the upper ring surface of described support ring and pressure ring is provided with V-arrangement bulge loop and the V-arrangement scrobicular ring that is interlocked with the font of falling V, and support ring and pressure ring are made up of lobe two bodies.Fracture on the described seal ring is a tilting, and two adjacent interruptions interlace 90 °-180 °.The utility model compared with prior art has following advantage: working stability is reliable, because seal ring is the font of falling V, make the V word bore of seal ring to opening, all the time be posted by on the travel axis, even during the seal ring gauge wear, also can obtain effectively compensation by the axle power external force that acts on the pressure ring, it has not only improved sealing effect, has also prolonged working life.The utility model can in time be changed, beat is fast, need not save time by supplementary equipment, laborsaving, can improve greatly to tell on.
Description of drawings: Fig. 1 is the utility model half section structural representation.
Embodiment is done further narration below in conjunction with accompanying drawing to the utility model.
See also Fig. 1.As can be seen from the figure, the utility model comprises support ring 11, pressure ring 7 and row's seal ring 1, have a fracture 2 on the seal ring 1, this fracture is a tilting, fracture on adjacent two seal rings is staggered, and preferably interlaces 90 °-180 °, and the longitudinal cross-section of seal ring is the font of falling V 9, the following anchor ring of the upper ring surface of described support ring 11 and pressure ring 7 is provided with V-arrangement bulge loop 10 and the V-arrangement scrobicular ring 8 that is interlocked with the font of falling V 9, and this support ring 11 and pressure ring 7 are made up of 12,13 and 6,4 pairs of lobes of two bodies.During assembling, earlier support ring 11 is axially packed on the travel axis to lobe, seal ring 1 is rived from fracture 2 radially be inserted on the travel axis, more axially to the lobe pressure ring 7 of packing into, form a pair of support ring 11 down, seal ring is placed in the middle, pressure ring 7 is at last combination seal.During use, the rotation gland 3 of adjustable nodal axisn 5 outer ends even combination seal weares and teares for a long time, also can effectively be compensated, thereby has improved the sealing effect of combination seal and prolonged working life.
