Abstract
The utility model provides a high-temperature resisting bearing seal device and belongs to the technical field of bearing seal. The high-temperature resisting bearing seal device comprises a bearing outer ring, a bearing inner ring, a rolling body, a retainer, a spring steel plate, a contact sealing lip piece and an anti-dust cap; and the spring steel plate (3) is inserted into the bearing outer ring for fixing, the contact sealing lip piece is fixed in an inner ring of the spring steel plate (3) and firmly pressed on an oblique part of a V-shaped groove of the bearing inner ring, and the anti-dust cap (6) is fixed on the bearing outer ring (1). The high-temperature resisting bearing seal device has the advantages that the spring steel plate and the contact sealing lip piece form integral sealing. The spring steel plate is subject to annular W-shaped punching machining so as to have elastic compensation amount. The W-shaped ring can keep some compressed amount when in installation, so that certain pressure of the contact sealing lip piece is kept on the sliding face of the bearing inner ring; when a bearing expands or contracts by temperature changes, clearance amount exposed by common sealing can be elastically compensated by the W-shape ring of the spring steel plate automatically, thereby preventing loss of the lubricant and sewage from entering the bearing.
Description
Technical field
The utility model belongs to the bearing seal technical field, and a kind of high temperature resistant associated sealing arrangement for bearings particularly is provided, and is applicable to the bearing seal under the big operating mode of hot environment or difference variation.
Background technique
Bearing seal can be divided into contact-type and contactless two kinds, and contact-type has preferable sealing effect, and most bearings mainly use this sealing means.Contact seal at present has lip, Z-shaped consistent lubricant, V-ring, oil sealing and all kinds of to be combined to form sealing etc.; These are sealed under the high operating mode of worst hot case and rotating speed and all are easy to generate heat waste and wear out failure; Cause the lubricant flow dirt of becoming estranged to get into bearing; Shorten bearing life, even influence quality of product.Especially in some specific workplaces; Like continuous strip annealing furnace (the furnace gas composition is strict control); The effect of protection bearing is not only played in sealing, and what is more important will prevent that lubricant grease from getting into body of heater after inboard seepage, is promptly gasified by furnace high-temperature in case oiling agent gets into; Thereby destroyed the furnace gas composition, had a strong impact on the annealing quality of band steel.
Summary of the invention
The utility model axle is to provide a kind of high temperature resistant associated sealing arrangement for bearings; Solve bearing and under the high operating mode of worst hot case and rotating speed, all be easy to generate heat waste and wear out failure; Cause the lubricant flow dirt of becoming estranged to get into bearing, shorten bearing life, even influence quality of product.Bearing seal utilizes Steel Spring Plate to do bearing seal, and when sealing base surface generation heat waste and wearing and tearing, Steel Spring Plate can compensate automatically, keeps excellent sealing effect.
The utility model comprises bearing outer ring 1, bearing inner race 7, rolling element 2, retainer 4, Steel Spring Plate 3, contact seal lip sheet 5, dust cover 6.Bearing outer ring 1 processing groove, Steel Spring Plate 3 embeds bearing outer ring and fixes; Contact seal lip sheet 5 is fixed on the Steel Spring Plate 3 interior circles, forms bearing seal with Steel Spring Plate; Bearing inner race 7 is processed into " V " shape groove, and contact seal lip sheet 5 is close to bearing inner race " V " incline section of shape groove, cooperate with bearing inner race 7 " V " shape groove to form contact seal; Dust cover 6 is fixed on the bearing outer ring.
The ring Steel Spring Plate that the said Steel Spring Plate 3 of the utility model is a 0.2mm-0.8mm thickness; And on annulus, carry out " w " shape (waveform) (w shape ring 2-4 group of ring-type; 25 °-45 ° of angles; Height 1.5-3.5mm) punch process, " w " shape ring is positioned in the middle of annulus cylindrical and the circle, makes it possess the radial elastic extending amount; 4 V-arrangement gradual changes of Steel Spring Plate 3 internal ring portions punching press in the horizontal and vertical directions groove, length 5-30mm, 40 ° of V-arrangement angles, maximum height 2-4mm makes to encircle in it to possess the ring-type swell-shrinking property; Then the Steel Spring Plate 3 that processes is carried out corresponding heat treatment (quenching+medium-temperature tempering); Contact seal lip sheet 5 is high temperature resistant, wear-resisting lip seal ring material (the combined packing ring of viton, asbestos and graphite etc.); According to circle pattern processing groove in " w " shape ring-spring steel plate 3, Steel Spring Plate 3 embeds contact seal lip sheet 5 on the contact seal lip sheet 5; Even after lip pad wear distortion at high temperature or the fatigue deformation, still can be by " w " thus shape ring-spring steel plate 3 carries out elastic compensating keeps sealing effect.
" w " shape ring-spring steel plate 3 is referred to as the Steel Spring Plate sealing after making up with contact seal lip sheet 5.
Certain decrement (amount of being full of is at 0.4-1mm) is held in Steel Spring Plate sealing " w " shape environmental protection when mounted; Make contact seal lip sheet 5 have certain contact pressure to remain on bearing inner race 7 slip surfaces all the time, the gap value that conventional seals was exposed when bearing received temperature variation breathing can carry out elastic compensating by " w " shape ring of Steel Spring Plate 3 fully automatically.Owing to have elastic compensating and the tolerable axle has certain axial deflection, sealing has good sealing effect applicable to each class bearing.
The advantage of the utility model is:
1, material is common, and making is simple, processing cost is low.
2, under hot environment or temperature gradient variation operating mode greatly, still can keep good sealing effect; It is made by Steel Spring Plate.It embeds bearing outer ring, forms motive sealing with bearing inner race, prevents that the lubricant flow dirt of becoming estranged from getting into bearing.
3, the certain axial deflection of tolerable axle and bearing can be ignored the influence of bearing clearance, is applicable to each class bearing.With plain bearing sealing mounting point the same (being between retainer and the dust ring), can all install according to installation of operating mode single face or bearing both sides.
4, sealing lip sheet side direction contact, contact pressure is little, and friction torque and temperature rise are low, and the lip sheet can carry out springback compensation by Steel Spring Plate after damaging, and has guaranteed sealability.
5, " w " row ring of being processed into of Steel Spring Plate, it is positioned at sealing steel plate middle part, does not clash with retainer, and 4 V-arrangement gradual changes of punching press groove on ring level and the vertical direction in Steel Spring Plate makes to encircle in it to possess the ring-type swell-shrinking property; " w " row ring must keep certain decrement when Steel Spring Plate was installed, and made contact seal lip sheet have certain contact pressure to keep bearing inner race on slip surface all the time, elastic compensating automatically when slip surface is gapped.
The innovative point of the utility model is to have adopted " W " shape Steel Spring Plate that is processed into ring-type; Metal frame sealing different from the past; It not only can be high temperature resistant; The more important thing is to provide the radial elastic compensation, and allows axle and the certain axial deflection of bearing, has solved the receptance of V-shaped groove to axial internal clearance.
