Abstract
The utility model discloses a kind of bearing combined seal structure, there is the inside and outside circle of bearing and Sealing, it is characterized in that: described Sealing comprises dust guard, seal steel plate and has the seal ring on lip limit; Described dust guard prevents dust and stops large granular impurity to enter sealing configuration, and protection seal steel plate is from collision deformation, and described seal steel plate and seal ring complement each other to form and can prevent liquid water and steam from entering sealing configuration in seal; Described dust guard internal diameter, with bearing inner race interference fit, produces fixing; Described seal steel plate is positioned at inside dust guard, and cross section is L-shaped, and its internal diameter is with bearing inner race interference fit; The external diameter of described rubber seal and bearing outer ring interference fit, its lip limit respectively with seal steel plate and inner ring interference fit.The utility model, owing to adopting combined sealing structure, makes bearing be greatly improved working life out of doors, has saved design space and cost of production.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to one and is provided with combined sealing structure, has better sealability, be specially adapted to the bearing of outdoor study.
Background technique
For the bearing worked out of doors for a long time, due to often rain, mud and steam in environment, and the sealing configuration of some conventional bearings of prior art, simple dust-proof effect can only be played, sealability for liquid water and steam is not good, causes Bearing inner to be easy to by corrosion, thus makes greatly shortening with the life-span of bearing, both waste national resources, turn increase maintenance expenses.
Summary of the invention
The utility model mainly solves the deficiency existing for prior art, thus the combined seal structure bearing that exploitation one is applicable to normally work out of doors, can effectively prevent rainwater, steam enters.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of bearing combined seal structure, has the inside and outside circle of bearing and Sealing, it is characterized in that:
Described Sealing comprises dust guard, seal steel plate and has the rubber seal on lip limit; Described dust guard prevents dust and stops large granular impurity to enter sealing configuration, and protection seal steel plate is from collision deformation, and described seal steel plate and seal ring complement each other to form and can prevent liquid water and steam from entering sealing configuration in seal;
Described dust guard internal diameter, with bearing inner race interference fit, produces fixing;
Described seal steel plate is positioned at inside dust guard, and cross section is L-shaped, and its internal diameter is with bearing inner race interference fit;
The external diameter of described rubber seal and bearing outer ring interference fit, its lip limit respectively with seal steel plate and inner ring interference fit.
The technical solution of the utility model can also be perfect further:
As preferably, described rubber seal has lip limit one, lip limit two and lip limit three; Described lip limit together seal steel plate produces axial interference, and its angle is greater than 90 °; Lip limit two produces interference fit with the outer diameter face of the L-shaped seal steel plate in cross section, and its angle is greater than 90 °; Lip limit three produces interference with the rib external diameter of bearing inner race, and crimping bends laterally, and crimping end forms angle with the rib diameter of inner ring.
The beneficial effects of the utility model are:
Because this combined sealing structure is made up of dust guard, seal steel plate and seal ring three part with lip limit, dust guard has higher intensity, plays protection collision and dustproof effect; Seal steel plate machining accuracy is high but sheet material is thinner, and seal steel plate complements each other to form sealing with the seal ring with lip limit, and under extraneous liquid impacts, sealability will be more excellent, can play the effect of anti-liquid water, anti-steam.
The application of this combined sealing structure, makes bearing be greatly improved working life out of doors, and after bearing possesses sealing structure simultaneously, its matched host machine, without the need to separately making protection work for bearing again, has saved design space and cost of production.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is combined sealing structure enlarged views of Fig. 1;
Accompanying drawing 3 is that seal steel plate and seal ring complement each other to form sealing configuration enlarged view.
Description of reference numerals:
1, bearing outer ring, 2, Sealing, 3, bearing inner race, 21, dust guard, 22, seal steel plate, 23, rubber seal, 231, lip limit one, 232, lip limit two, 233, lip limit three.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Bearing combined seal structure as shown in Figure 1, has bearing inner race 3, bearing outer ring 1 and Sealing 2.
Described Sealing as shown in Figure 2, comprises dust guard 21, seal steel plate 22 and has the rubber seal 23 on lip limit.
Described dust guard 21 prevents dust and stops large granular impurity to enter sealing configuration, and protection seal steel plate is from collision deformation, and described seal steel plate 22 and rubber seal 23 complement each other to form and can prevent liquid water and steam from entering sealing configuration in seal.
Described dust guard 21 internal diameter, with bearing inner race 3 interference fit, produces fixing;
Described seal steel plate 22 is positioned at inside dust guard 21, and cross section is L-shaped, and internal diameter is with bearing inner race 3 interference fit, and described seal steel plate machining accuracy is higher, but sheet material thinner thickness, suitable cooperation with the lip limit of rubber seal 23 forms sealing configuration;
The external diameter of described rubber seal 23 and bearing outer ring 1 interference fit, it has the key point that lip limit 1, lip limit 2 232 and lip limit, 3 233, three, lip limit are sealing structures.
Lip limit 1 produces axial interference with seal steel plate 22, hinders foreign matter and steam to enter, simultaneously, lip limit together seal steel plate formed as shown in Figure 3 be greater than 90 ° of angles, when external fluid material impact lip limit 1 time, angle can be made to reduce, lip limit is close to more with steel disc, and sealability is better;
Lip limit 2 232 produces interference fit with the outer diameter face of the L-shaped seal steel plate 22 in cross section, and the angle that lip limit two is formed with outer diameter face is similar with lip limit one, is beneficial to and prevents external substance from entering;
Lip limit 3 233 produces interference with the rib external diameter of bearing inner race 3, and crimping bends laterally, the angle that crimping end is formed with the rib diameter of inner ring, makes lip limit more be close to rib when being subject to external fluid material and impacting.
The utility model cooperatively interacts due to dust guard, seal steel plate and seal ring, and what its sealing configuration effectively can prevent liquid water, steam enters Bearing inner, and bearing is normally worked for a long time out of doors.
