Describe preferred embodiment of the present utility model with reference to the accompanying drawings in detail.
At first referring to Fig. 1 and Fig. 2, the utility model first embodiment's dicyclo divided bearing protector comprises outer shroud 10 and the interior ring 20 that remains in the outer shroud.
Outer shroud 10 by elastic material for example rubber-plastics material make, in use be installed in still on the frame of equipment.The periphery of outer shroud 10 is provided with the annulus 14 of projection, so that outer shroud is installed on the frame.Outer shroud can be directly installed on the frame, or is installed on the frame by auxiliary element.In order to improve the static seal performance between bearing protector and the frame, the outer circumferential side of outer shroud can the suit elastic sealing ring.
Outer shroud 10 is firmly held in interior ring 20 wherein.Outer shroud 10 encircles 20 girths at the interface at the two in the girth at the interface of the two is slightly less than, make thus to have interference fit between outer shroud 10 and the interior ring 20.In order to keep the connection of the two, the shape of ring in the inboard of outer shroud is provided with and is suitable for keeping.For example, the interior ring tank that is complementary by the peripheral shape with interior ring is offered in the inboard of outer shroud, in ring tank in interior ring is remained on compactly.After being assemblied in the elasticity hold-fast ring on the outer shroud, on the ring, ring is kept static with outer shroud in guaranteeing thus with respect to frame in outer shroud can being pressed on.As an alternative or addition thereto, can apply tackiness agent between interior ring and the outer shroud.
Outer shroud 10 is discrete ring also, but has the subdivision ring of an otch 12.That is to say that at otch 12 places, outer shroud 10 disconnects.Otch 12 can be straight otch.Perhaps, more preferably, otch 12 has insertion type joint 16, as described later.
Be sleeved in the rotating shaft of equipment interior ring 20 also by elastic material for example rubber-plastics material make.Interior ring 20 can be identical with outer shroud 10 used materials, also can be different.In addition, the two can have different colors, so that make and maintenance.
The inboard of interior ring 20 is formed with a resilient lip 26 that slopes inwardly and extend, produced an annular groove 24 between this antelabium and the interior ring main body, and antelabium has the inboard coign portion 28 that points to, this coign portion forms a loop wire that contacts with the rotating shaft of equipment, and the girth of this loop wire is slightly less than the periphery girth of rotating shaft.In use, interior ring 20 is sleeved in the rotating shaft, and this coign portion 28 contacts with the rotating shaft periphery and is slidingly matched, and is strutted slightly by rotating shaft, promptly omits micro-elasticity laterally and returns.Thus, antelabium 26 by its coign portion 28 with certain continuously, uniformly elastic thrust closely around pushing and pressing on the rotating shaft periphery, and can between interior ring and rotating shaft, not stay the slit.
Interior ring 20 is the subdivision rings with an otch 22, and at otch 22 places, interior ring 20 disconnects.Otch 22 can be straight otch.The otch 22 of interior ring 20 and the otch 12 of outer shroud 10 for example 5 ° to 180 °, preferred 10 ° to 90 °, can improve sealability thus at the several angle that upwards staggers in week.
Because outer shroud and interior ring all are the subdivision rings that has otch, therefore,, the bearing protector directly can be installed to axle and go up or pull down, and can not be subjected to the interference of other part from axle by this otch.Simultaneously, because the otch of outer shroud and interior ring is each other along circumferentially the staggering of bearing protector, extraneous foreign matter is difficult to pass simultaneously these two otch and invades the bearing protector, and therefore, the sealability of bearing protector can improve.
For the ability of holding tightly that improves bearing protector countershaft and therefore improve sealability, can adopt one to be sleeved on the outer shroud outer shroud and interior ring are packed tightly the elasticity hold-fast ring 30 in rotating shaft.The outer circumferential side central authorities of outer shroud 10 are provided with the elasticity hold-fast ring and hold annular groove 32 (see figure 2)s, are used for elasticity hold-fast ring 30 is contained in wherein.The length of elasticity hold-fast ring 30 is held the girth of annular groove less than the elasticity hold-fast ring.Elasticity hold-fast ring 30 can be the continuous uninterrupted ring, holds in the annular groove by 30 supports of elasticity hold-fast ring can be embedded it elasticity hold-fast ring greatly.Perhaps, elasticity hold-fast ring 30 can disconnect, and promptly is a long strip under normal conditions, the dismounting of being more convenient for of this elasticity hold-fast ring that disconnects.Elasticity hold-fast ring 30 is being inserted after the elasticity hold-fast ring holds in the annular groove, the elasticity hold-fast ring elongated so that it joins end to end connects, thereby outwards circulating application adds compressive force, make it pack tightly interior ring with the constraint outer shroud, under the rebounding force effect of the package power of outer shroud and interior ring, realize reliable sealing between the inner and outer rings like this; In the case,, can be provided with fast joint structure, for example have contact with structure at the head and the tail two ends of elasticity hold-fast ring 30 for the ease of 30 the joining end to end of tensile elasticity hold-fast ring own.
For the joint between ring and the outer shroud in improving, contacted position can be provided with the structure that is complementary between the two, and for example interior ring is provided with to the outstanding projection of outer shroud, and outer shroud is provided with the groove that is used to hold described projection, and vice versa.
In addition, between interior ring and the outer shroud or the two outside can be provided with auxiliary seal subdivision ring, to play the auxiliary seal effect.
As an additional useful feature, the flexible compensation piece (not shown) that at otch 22 places of interior ring 20, add that ring in the ratio is 20 soft, transverse shape and interior ring 20 is identical, then the meeting of sealing and assembling effect is better.
As an additional useful feature, the elasticity hold-fast ring can also be used as elastic sealing ring simultaneously.Particularly, the shape of cross section (not shown) of elasticity hold-fast ring can be configured to be suitable for the pilot hole butt with frame, thereby after the bearing protector is assembled in the frame, improves the static seal performance between bearing protector and the frame
The insertion type joint 16 of uniqueness of the present utility model is described below with reference to Fig. 3.
Otch 12 places of outer shroud 10 can form insertion type joint 16.That is to say that at otch 12 places, an end of outer shroud has outstanding insertion part, it is along circumferentially giving prominence to and bloating to both sides; The other end of outer shroud has the groove shaped holding part that is complementary with the insertion part.Like this, at insertion type joint 16 places along radially the seeing of bearing protector, being shaped as of insertion part, from front end, transverse dimension increases gradually, after increasing to a certain degree, transverse dimension reduces again gradually.Therefore, the transverse dimension of the front-end and back-end of insertion part is less than the intermediate portion, and the groove shaped holding part then has corresponding matched shape.For this reason, when inserting in the holding part in described insertion part, the insertion part will strut holding part to both sides earlier, just can enter in the holding part.After the insertion part enters in the holding part, the original shape of holding part elastic return, the two formation closely cooperates, and makes outer shroud form a whole annulus thus.Because therefore the insertion part generally will require insertion part and holding part to have enough elasticity along in the circumferential insertion holding part.
Along radially the seeing of bearing protector, the shape of insertion part can be circle, ellipse, rhombus, other laterally protrudes shape or difform combination or the like at insertion type joint 16 places.
By adopting insertion type joint 16, can improve the structural integrity of outer shroud and even whole bearing protector, work more reliably to guarantee the bearing protector.
Next the utility model second embodiment's dicyclo divided bearing protector is described with reference to Fig. 4.
Second embodiment and aforementioned first embodiment are essentially identical on overall structure, and therefore identical part is repeated description no longer.Only introduce second embodiment's difference below.
The front was described, and antelabium 26 closely pushes against on the rotating shaft periphery with certain elastic thrust by its coign portion 28.Yet, for the reason of antelabium 26 self structure or material, or because the variation of conditions such as the temperature in the work, pressure, or after having passed through long-term use, this elastic thrust may be not enough, thereby ring can not be held tightly in rotating shaft reliably in causing.For this reason, second embodiment's key character is, added one its hold the axle type spring 40 of effect tightly, to increase the elastic thrust of antelabium 26 in rotating shaft and the effect of holding tightly of interior ring countershaft, ring is to the power of holding tightly the effect and the seal action of outer shroud extroversion in can increasing simultaneously.
As shown in Figure 4, axle type spring 40 is O shape in the transverse section, and it is inlaid in the annular groove 24 of interior ring 20.Similar with elasticity hold-fast ring 30, axle type spring 40 can be the continuous uninterrupted ring, also can be the ring that can disconnect.Under one situation of back,, can be provided with fast joint structure at the head and the tail two ends of axle type spring 30, for example shackle or CONCENTRIC REDUCER intercalation structure for the ease of 30 the joining end to end of axle type spring own.
Among second embodiment of Miao Shuing, be provided with the elasticity hold-fast ring and the axle type spring that are used to hold tightly simultaneously in the above.Yet, in the 3rd embodiment of the present utility model, only be provided with the axle type spring in the ring in being inlaid in, and do not have to be provided with the elasticity hold-fast ring that is inlaid in the outer shroud.In this case, by internal the packing tightly and the effect of outer ring strain of ring of axle type spring, still can realize the seal action of holding tightly of whole bearing protector and countershaft.
By top preferred embodiment is done to describe as can be seen, the utility model has adopted to be held mechanism tightly and has improved dicyclo divided bearing protector self and pack tightly the ability of holding tightly with countershaft, has also just therefore improved sealability.The mechanism of holding tightly can be inlaid in elasticity hold-fast ring in the outer shroud, be inlaid in in the ring axle type spring these two one of or whole.
