Description
Technical field
The utility model relates to field of bearings, especially a kind of band thrust plate for transmission input shaft and the integrated drawn cup roller bearing of oil sealing.
Background technique
Spring bearing and the oil sealing of conventional transmission input shaft need to press-fit respectively in installation process, install inconvenient, waste time and energy.In addition, if bearing is subject to certain axial force, can oil sealing be collided, the sealing of oil sealing after Long-Time Service, can be affected.
In prior art, in the assembly process of transmission input shaft, be all adopt first to press-fit spring bearing, and then press-fit oil sealing.Two procedures is separately carried out, and not only wastes time and energy, and higher for the requirement of press-loading device.Press-fit operation to simplify, the utility model on the basis of existing technology, carries out integrated to spring bearing, in advance by oil seal pressing in bearing, in the assembly process of transmission input shaft, only need pressing bearing, simplify press-loading process.Meanwhile, by oil seal pressing in bearing, also save the space that oil sealing itself is shared.
Because spring bearing can be subject to responsive to axial force, clash into oil sealing and cause oil sealing to damage, therefore, the utility model is provided with thrust plate between oil sealing and retainer, thrust plate can play the effect of buffering, and thrust plate and bearing outer ring interference fit, installing/dismounting is more convenient.
Described thrust plate top and oil sealing bottom lean, and are provided with gap between thrust plate bottom and retainer top, and certain space can be reserved for retainer in this gap, if retainer occurs to vibrate by a small margin, can not clash into thrust plate.
Be arranged in bearing outer ring for the ease of oil sealing, step is provided with in described bearing outer ring, bearing outer ring top is provided with draw-in groove, described oil sealing bottom is arranged on step, oil sealing top is connected in draw-in groove, this structure makes to coordinate between oil sealing with bearing outer ring closely firmly, not easily deviates from, and easy for installation.
In order to prevent oil sealing from sliding at bearing outer ring inwall further, described oil sealing outer wall is provided with slideproof tooth, and slideproof tooth increases the frictional force of oil sealing and bearing outer ring inwall, thus ensure that sealability.
The beneficial effects of the utility model are: the utility model band thrust plate and the integrated drawn cup roller bearing of oil sealing, the oil sealing of gearbox axle head and spring bearing are carried out integrated, facilitate installation, owing to adding thrust plate, avoid bearing axial force to the impact of oil sealing, ensure that sealability, improve the working life of bearing.
Model utility content
The technical problems to be solved in the utility model is: in order to provide a kind of good sealing effect, long service life, easy for installation, effectively can save space-efficient band thrust plate and the integrated drawn cup roller bearing of oil sealing.
The utility model solves the technological scheme that its technical problem adopts: a kind of with thrust plate and the integrated drawn cup roller bearing of oil sealing, the roller comprising bearing outer ring, be arranged on the retainer in bearing outer ring and be arranged in retainer, oil sealing is provided with in described bearing outer ring, described oil sealing is fixed on bearing outer ring top, is fixed with thrust plate between described oil sealing and retainer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the integrated drawn cup roller bearing of the utility model band thrust plate and oil sealing;
In figure: 1. bearing outer ring, 2. roller, 3. retainer, 4. thrust plate, 5. oil sealing, 6. steel ring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of with thrust plate and the integrated drawn cup roller bearing of oil sealing, the roller 2 comprising bearing outer ring 1, be arranged on the retainer 3 in bearing outer ring 1 and be arranged in retainer 3, oil sealing 5 is provided with in described bearing outer ring 1, described oil sealing 5 is fixed on bearing outer ring 1 top, is fixed with thrust plate 4 between described oil sealing 5 and retainer 3.
Be provided with step in described bearing outer ring 1, the internal diameter of this ring-shaped step is equal to or less than the internal diameter of oil sealing 5, and therefore, when all being pressed fit in bearing outer ring 1 by oil sealing 5, oil sealing 5 bottom is resisted against on step, and step can also play spacing effect to oil sealing 5.Bearing outer ring 1 top is provided with draw-in groove, in fact, bearing outer ring 1 top inwall has annular notches, and bearing outer ring 1 top extends internally, form annular preform, the internal diameter of annular preform is less than the external diameter of oil sealing 5, when all being pressed fit in bearing outer ring 1 by oil sealing 5, oil sealing 5 top can compress by annular preform, thus oil sealing 5 is limited between ring-shaped step and annular preform.This structure makes to coordinate between oil sealing 5 with bearing outer ring 1 closely firmly, not easily deviates from after press-fiting.
Described oil sealing 5 outer wall is provided with slideproof tooth, and namely oil sealing 5 outer wall is rough tooth slot structure, and this structure increases oil sealing 5 and the frictional force of bearing outer ring 1 inwall, prevents oil sealing 5 from deviating from, thus ensure that sealability.
This oil sealing 5 comprises outer ring and inner ring, is oil pocket between outer ring and inner ring, and in order to prevent inner ring from deforming, inner ring overcoat has steel ring.
Annular thrust plate 4 is provided with between oil sealing 5 and retainer 3, thrust plate 4 also comprises outer ring and inner ring, changeover portion is provided with between outer ring and inner ring, the outer ring outer wall of thrust plate 4 and bearing outer ring 1 inwall interference fit, in fact, bottom, thrust plate 4 outer ring fold inward forms inner ring, and the internal diameter of inner ring is less than the internal diameter of retainer 3, thrust plate 4 top and oil sealing 5 bottom lean, and are provided with gap between thrust plate 4 bottom and retainer 3 top.When bearing is subject to responsive to axial force, retainer 3 can not directly clash into oil sealing 5, but clashes into the changeover portion of thrust plate 4; namely there is bending in the changeover portion of thrust plate 4, thus protects oil sealing 5, when losing responsive to axial force; due to elastic reaction, the changeover portion of thrust plate 4 sets back.
Compared with prior art, the utility model band thrust plate and the integrated drawn cup roller bearing of oil sealing, the oil sealing 5 of gearbox axle head and spring bearing are carried out integrated, facilitate installation, owing to adding thrust plate 4, avoid bearing axial force to the impact of oil sealing 5, ensure that sealability, improve the working life of bearing.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
