Technical field
The utility model relates to a kind of sealing configuration, particularly relates to a kind of sealing configuration of joint shaft bearing bearing for building.
Background technique
In engineering practice, because of structural system safety requirement, need to design pin rocker bearing, by the rotation release moment of flexure of mechanism.Joint shaft bearing is exactly the most frequently used a kind of mechanism rotating release moment of flexure.The angle contact joint bearing hinged supporting base of the patent No. 200920212589.6, bear thrust load and larger radial load simultaneously, its pin is laterally inserted in the through hole of Cast-steel Sleeve, pin is placed inserting bolt after axle end baffle plate, Cast-steel Sleeve is connected with the second axle with Cast-steel Sleeve, first axle is laterally inserted in the through hole of the second axle, bearing is arranged on the bore place of the first axle, cover plate is arranged on Cast-steel Sleeve, oil sealing dress on the cover board places pressing plate afterwards, by the first nut of screwing on behind the first stud insertion through hole, second stud is inserted in the tapping of cover plate, second nut and the 3rd nut are screwed on the second stud.By the first axle, the angular contact articulated bearing arranged in pairs is linked to be entirety, two groups of same centers of circle of bearing, the same turning radius.When external load passes to above-mentioned axle, cause the distortion of axle, now there is Relative sliding in two groups of bearings on respective inside and outside ring interface, thus realize rotating.Finally by Cast-steel Sleeve by component package wherein, be isolated from the outside, avoid the corrosion of bearing, axle, ensure that its turning power is not weakened.The environment used due to joint shaft bearing for building is more severe, this just needs joint shaft bearing to seal in bearing spider, and existing sealing configuration adopts oil sealing, because the second beam warp often rotates, and oil sealing is static sealing, it can not move with the second axle, long when deployed, and oil sealing will produce distortion, make to produce gap between oil sealing and the second axle, the effect of sealing is good not, and existing oil seal structure is also very complicated, and cost is relatively high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of good sealing effect, can realizes dynamic seal (packing) and the sealing configuration of joint shaft bearing bearing for building with low cost.
For achieving the above object, the technical solution of the utility model is:
A kind of sealing configuration of joint shaft bearing bearing for building, it comprises bearing spider, joint shaft bearing outer ring is embedded in bearing spider, inner ring is set in the axle head of building support, described bearing spider is provided with sealing surface in one end of building support axle head, the relative the other end end face of the sealing surface of described bearing spider is provided with seal ring, seal ring is set on the axle of building support, seal ring is provided with sealing cover, described sealing cover is fixed on the end face of bearing spider, the receiving cavity of seal ring is formed between sealing cover and bearing spider, the height of described receiving cavity is more than or equal to the thickness of seal ring, the external diameter of receiving cavity is greater than the external diameter of seal ring, described seal ring is when the axle of building support turns to limit position, seal ring edge is in receiving cavity, lubricant oil is provided with between described seal ring and the surface of contact of receiving cavity.
Adopt above structure, the width of seal ring needs enough wide, to guarantee that, in the movement process of the axle of building support, the edge of seal ring is still positioned at receiving cavity, keeps sealing effect.Seal ring rotates along with the rotation of the axle of building support, tightly be enclosed within the axle of building support, form dynamic seal (packing), seal ring edge is all the time in receiving cavity, the surface of contact of seal ring and receiving cavity is added with lubricant oil, seal ring edge can be slided in receiving cavity, and lubricant oil also can play the effect of sealing simultaneously.
The internal diameter of described sealing cover is more than or equal to the internal diameter of the other end end face of bearing spider.Adopt this structure, the rotation of the axle of the more effective guarantee joint shaft bearing of energy and building support is unaffected.
Described sealing cover inwall and seal ring joint are provided with chamfering.Adopt this kind of structure to facilitate the effective exercise of seal ring, ensure the effect of dynamic seal (packing).
Described bearing spider and seal ring joint are provided with chamfering.Adopt this kind of structure to facilitate the effective exercise of seal ring, ensure the effect of dynamic seal (packing).
The utility model adopts above structure, by bearing spider is provided with sealing surface at an end face of building support axle head, the relative the other end end face of the sealing surface of described bearing spider is provided with seal ring, seal ring is set on the axle of building support, seal ring is provided with sealing cover, described sealing cover is fixed on the end face of bearing spider, the receiving cavity of seal ring is formed between sealing cover and bearing spider, the height of described receiving cavity is equal with seal ring thickness, the external diameter of receiving cavity is greater than the external diameter of seal ring, achieve seal ring can at any time the axle of building support rotation and rotate, its tightly be enclosed within the axle of building support, form dynamic seal (packing).Sealing effect is better, and seal ring is not easy distortion, durable in use, sealing configuration with low cost.
