Abstract
The utility model discloses an bearing sealing, which is composed of a bearing seat, a gland bush that is connected on the bearing seat by a fastening piece, a seal disc that can rotate with the rotating shaft is arranged in the bearing seat, a sealing clearance is formed between the corresponding surfaces of the seal disc and the bearing seat, therefore the utility model has the advantages of a striking effect of dustproof, long working life of the bearing, simple structure, convenient manufacturing, no need to maintain frequently, labor saving, resource saving and time saving.
Description
Technical field
The utility model relates to a kind of seal arrangement of protecting bearing.
Background technique
The sealing of bearing support in the past all is by the bearing (ball) cover inner ring is become a ditch that about 10mm is dark by machined into, when installing, asbestos rope is wound in the ditch, seal by the friction between asbestos rope and the axle, time has been grown the problem that can occur excesssive gap between the two unavoidably, dust very capacity enters in the bearing support, particularly under rugged environment, can reduce greatly the working life of bearing.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of sealing effect better associated sealing arrangement for bearings.
For achieving the above object, the technical solution of the utility model is: associated sealing arrangement for bearings, comprise bearing support, be fixedly connected on the bearing gland of described bearing support one side end by fastening piece, the seal disc that can rotate with rotating shaft is installed in described bearing support, has seal clearance between the respective surfaces of described seal disc and described bearing support.
As a kind of improvement, described seal disc axial clamp is pressed between the shaft shoulder of bearing inner race and rotating shaft.
As a kind of further improvement, described seal disc is provided with protruding circle vertically, and the inner surface of described bearing support is provided with and the suitable annular groove of the protruding circle of described seal disc, and described protruding circle stretches in the described groove.
Owing to adopt technique scheme, associated sealing arrangement for bearings comprises bearing support, is fixedly connected on the bearing gland of described bearing support one side end by fastening piece, the seal disc that can rotate with rotating shaft is installed in described bearing support, have seal clearance between the respective surfaces of described seal disc and described bearing support, so sealing and dustproof is effective, bearing is long service time, and it is simple in structure, be convenient to processing and manufacture, need not frequent maintaining, save great amount of manpower and material resources and time.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
Associated sealing arrangement for bearings as shown in drawings, comprise bearing support 1, be fixedly connected on the bearing gland 3 of described bearing support 1 one side ends by fastening piece, the seal disc 2 that can rotate with rotating shaft is installed in described bearing support 1, has seal clearance between the respective surfaces of described seal disc 2 and described bearing support 1, described seal disc 2 axial clamp are pressed between the shaft shoulder of bearing inner race and rotating shaft, described seal disc 2 is provided with protruding circle vertically, the inner surface of described bearing support 1 is provided with and the suitable annular groove of the protruding circle of described seal disc 2, described protruding circle stretches in the described groove, thereby make lubricant oil when entering bearing, can only enter in the bearing along the gap between described seal disc 2 and the described bearing support 1, so needed time is longer, prolonged the working life of bearing.
Claims (3)
