Description
Technical field:
The present invention relates to Sealing, particularly rolling bearing end-face seal ring in a kind of mechanical manufacturing field.
Background technique:
Modal at present, the dynamic seal ring of related protection rolling bearing has two kinds, and a kind of is with flexible rubber, plastic materials manufacturing, plays the oil sealing that abbreviates as of seal action by the surface of touch scrolling bearing output shaft.Another kind mainly is with nonmetallic material manufacturings such as engineering ceramicss, earlier be installed in output shaft and fixedly make outside static seal on the endoporus of rolling bearing by rubber part, engineering ceramics behind two precise finishes of cooperation assembling is made plane contact mutually again, seal action is played in the motion that closely cooperates under spring pressure, abbreviates water seal as.Though all be to reach sealing purpose in various mode, also some shortcomings of existence in various degree.Mostly be and axle surface contact seal that as the oil seal washer of flexible rubber, plastic materials manufacturing sealing effect is subjected to part surface degree of finish, axle rotational speed, many-sided restriction such as sealing material is aging.And the water seal circle of engineering ceramic material can be subjected to complex structure, and the spatial position is big, and the influence of maintenance inconvenience and the more high factor of cost is used less.
Summary of the invention:
The objective of the invention is for solving the problem of above-mentioned existence, and provide a kind of good seal performance, reliability height, long service life, compact structure, rolling bearing end-face seal ring with low cost.
The present invention is made up of inside and outside circle metal frame, dish-shaped metal spring and seal ring, be equipped with the internal diameter step that is complementary with dish-shaped metal spring in the metal frame of outer ring, the inner ring metal frame is to be drawn into the straight-through stepped cylindrical shape in big or small two, dish metal spring external diameter places in the internal diameter step of outer ring metal frame, internal diameter and inner ring metal frame stretching microcephaly do the flange riveted joint and are one, the surface coverage glued membrane, seal ring is installed in the inner chamber of the inner ring metal frame that is coated with glued membrane, and outer ring metal frame and rolling bearing shell end face are equipped.
Described outer ring metal frame is that its outside diameter is less than or equal to the outside diameter with the rolling bearing that is equipped with steel material processing ringwise; The diameter of endoporus is more than or equal to the diameter of the interior moving-coil of the bearing that is equipped with, the Transverse plane of outer ring metal frame is provided with two kinds of steps, a kind of is the internal diameter step, another kind is a small stair, this small stair all equally is crisscross arranged respectively on the Transverse plane of outer ring metal frame, the quantity of small stair is more than at least 4 pairs, and the height of its internal diameter step is corresponding with the thickness of the spring sheet of dish-shaped metal spring.
Described inner ring metal frame becomes the straight-through stair-stepping cylindrical shape in large and small two that has by sheet metal stretch, and the internal diameter flange riveted of its microcephaly's cylinder and belleville spring is equipped, and the major part cylinder bore behind the injecting glue film is equipped with mutually with seal ring.
One of them end face ecto-entad of described seal ring, the directive above tiny groove at least 4 roads that is being provided with, the diameter of the sealing ring intracavity diameter after more than or equal to glued membrane on the inner ring metal frame.Seal ring is by engineering ceramics, metal, nylon, teflon or vulcanite or plastic production.
Described dish-shaped metal spring is to be processed into by sheet metal that cylindrical is connected as a single entity, interior round equal portions are divided into the strip of sheet more than 2, the diameter of its cylindrical is less than or equal to the diameter of internal diameter step on the metal frame of outer ring, and interior circular diameter is big or small corresponding with inner ring metal frame small diameter cylinder.
Described glued membrane is the rubber or the elastomeric plastics of hard material.
Owing to adopted said elements and fit, during work: rolling bearing end-face seal ring and rolling bearing are same to be placed in the bearing hole, the end face step of outer ring metal frame is compressed by bearing cap, is pressed on the rolling bearing shell end face step of correspondence fastening with it.The external diameter of outer ring metal frame has the rubber material to cooperate the static seal effect of playing with bearing hole.Turn over the dish-shaped metal spring of angle in having, be driven plain under external force and produce pressure, the reaction force that utilizes spring is close to the end face of seal ring precise finish processing an end face of rolling bearing inner ring, the assurance bearing is issued in static and dynamic situation and prevents to sew purpose, in addition in order to prevent sewing between rolling bearing inner ring and the axle, can cooperate the liquid sealant assembling during installation, perhaps install " O " type rubber static seal circle additional in the junction of axle and bearing inner race.
Advantage of the present invention is: good seal performance, reliability height, and long service life, compact structure, with low cost.
