Abstract
The utility model relates to the technical field of sealing materials, in particular to a non-contact rubber sealing ring for a deep groove ball bearing. The sealing ring comprises a skeleton and a rubber sealing body wrapped at the periphery of the skeleton, wherein the rubber sealing body is divided into a sealing outer lip and a sealing inner lip; the skeleton is an L-shaped skeleton; an inclined angle is formed at the tail end of the skeleton; a design groove is formed on one side of the sealing outer lip; an inclined surface is formed between the other side of the sealing outer lip and the skeleton; the sealing inner lip adopts double lips; and a groove is formed in the middle of the sealing inner lip. The sealing ring for the bearing simplifies the process, improves the processing precision and the sealing clearance precision, avoids the influence of a roller path sidesway on the sealing property, enables the inner ring to be universal in use, is convenient to assemble, has excellent sealing property and dust tightness, reduces the noise vibration of the bearing, and has small friction moment and long service life.
Description
Technical field
The utility model relates to the sealing material technical field, the contactless rubber seal of especially a kind of deep groove ball bearing.
Background technique
The rolling bearing sealingization is to make one of machinery simplification, light-weighted necessary condition, and in stuffing box bearing, the structural design of seal ring has directly affected the performance of stuffing box bearing, therefore how to improve the performance of stuffing box bearing, becomes the problem of primary research.Common double-lip sealing ring inner ring all will be slotted, and production technology is comparatively complicated, and cost also increases thereupon.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of contactless rubber seal of deep groove ball bearing of not only having simplified technique but also having improved sealing and dust-protection type.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing sealed ring, comprise skeleton and be coated on skeleton rubbery sealed body on every side, described rubbery sealed body is divided into sealing outer lip and sealing epipharynx, described skeleton is " L " type skeleton, described skeleton end has the tilt angle, both can make cementability good, and can make again oiling agent that good backflow is arranged.
Further, described sealing outer lip one side offers a design groove, has the inclined-plane between described sealing outer lip opposite side and the skeleton, and described sealing epipharynx is lips, offers groove in the middle of the sealing epipharynx, is the storage area.When lubricating grease flows to groove by the gap, by fluid mechanics as can be known, when passage sections was long-pending large, speed obviously slowed down, and can relax thus the leakage of oiling agent.
Further, the radius of described design groove is identical with the radius of sealing outer lip, so that the seal ring fitness is good.
The beneficial effects of the utility model are, bearing sealed ring of the present utility model has been simplified technique, improve machining accuracy and seal clearance precision, can avoid the raceway side-sway on the impact of sealability, make again inner ring general, easy to assembly, have good sealing and protection against dust, reduced the noise vibration of bearing, and friction torque is little, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is generalized section of the present utility model.
Fig. 2 is that the utility model outer lip cooperates figure with the outer ring seal groove.
Fig. 3 is the skeleton comparison diagram before and after improving.
1. skeletons among the figure 2. seal outer lip, and 2-1. designs groove, and the 2-2. tilt angle 3. seals epipharynx, 3-1. groove.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Bearing sealed ring as shown in Figure 1, comprise skeleton 1 and be coated on skeleton 1 rubbery sealed body on every side, rubbery sealed body is divided into sealing outer lip 2 and sealing epipharynx 3, skeleton 1 is " L " type skeleton 1, skeleton 1 end has the tilt angle, both can make cementability good, and can make again oiling agent that good backflow is arranged.Sealing outer lip 2 one sides offer a design groove 2-1, have the inclined-plane between sealing outer lip 2 opposite sides and the skeleton 1, and sealing epipharynx 3 is lips, offers groove 3-1 in the middle of the sealing epipharynx 3, is the storage area.When lubricating grease flows to groove 3-1 place by the gap, by fluid mechanics as can be known, when passage sections was long-pending large, speed obviously slowed down, and can relax thus the leakage of oiling agent.Simultaneously, because the sticking action of fat makes on seal ring and the inner ring rib surface and retains lubricating grease, in the relative movement of inner ring-turning collar/seal ring-Jing Quan, the fat that retains is divided into two-part, being divided into two-part fat middle is the air clearance, has two-part lubricating grease between small air, can play good seal action, and in fact, groove 3-1 and lips are equivalent to 3 layers of labyrinth seal.And external dust is when invading, and the fat that is stored in the groove is caught, and discharges when inside and outside differential pressure replaces, and reaches dust-proof effect in addition, and the radius of design groove 2-1 is identical with the radius R 1 that seals outer lip 2, so that the seal ring fitness is good.
Fig. 2 cooperates figure for sealing outer lip 2 with the outer ring seal groove, the cooperation of the lip of seal ring installation is here mainly located by elastic force axial and radial compression and bending elasticity distortion, because magnitude of interference is large, so firm position is reliable like this, and improved the rigidity of seal ring and guaranteed the sealing of seal groove, the radius of R1 is identical with the outer ring groove radius, this just fully match the shape of outer ring recess, be that seal ring after the assembling and outer ring are without relatively rotating.
Fig. 3 is skeleton 1 comparison diagram before and after improving, and skeleton 1 design changes present right angle into by obtuse angle in the past, and like this, the sealing profile at a place just has individual tilt angle, both can make cementability good, can make again oiling agent at a place good backflow be arranged.In addition, increase again small bend angle at the b place, reached the effect of gaining in strength with cementability.
This shows that bearing sealed ring of the present utility model is good airproof performance not only, protection against dust is good, and friction torque is little, and temperature rise is low, and the life-span is long.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
