Description
Technical field:
The utility model relates to a kind of pump, particularly relates to a kind of bearing in pump box seal device.
Background technique:
In chemical industry, be extensive use of chemical pump, and all kinds of chemical pump, because what carry all is the liquid of severe corrosive, so, have higher requirement to the sealability of pump.The seal arrangement of common performance exists a lot of defectives, and working life is short, and sealability is poor, in actual use, can not satisfy the requirement of production.The phenomenon of often have race, emitting takes place, and brings serious pollution to production environment.
Summary of the invention:
The purpose of this utility model will provide a kind of bearing in pump box seal device exactly.The purpose of this utility model is to realize like this, a kind of Seal in Bearing Box device, formed by axle, back labyrinth bush, lubricating cup, bearing support, roller bearing, tapered roller bearing, bearing gland, preceding labyrinth bush, bearing sealed ring, it is characterized in that: be respectively arranged with forward and backward labyrinth bush at the two ends of axle, between back labyrinth bush and bearing support, be provided with lubricating cup, be provided with roller bearing in the described bearing support; Front end at axle is provided with preceding labyrinth bush, is provided with bearing sealed ring before described in the labyrinth bush, is provided with bearing gland in preceding labyrinth bush back, is provided with tapered roller bearing in the back of bearing gland.
The utility model is simple in structure, and is easy for installation, can not produce any leakage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the seal arrangement partial schematic diagram after amplifying
Axle, 2. the back labyrinth bush, 3. lubricating cup, 4. bearing support, 5. roller bearing, 6. tapered roller bearing, 7. bearing gland, 8. before labyrinth bush, 9. bearing sealed ring
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing
In the drawings, a kind of Seal in Bearing Box device of the utility model, formed by axle, back labyrinth bush, lubricating cup, bearing support, roller bearing, tapered roller bearing, bearing gland, preceding labyrinth bush, bearing sealed ring, it is characterized in that: be respectively arranged with forward and backward labyrinth bush at the two ends of axle, between back labyrinth bush and bearing support, be provided with lubricating cup, be provided with roller bearing in the described bearing support; Front end at axle is provided with preceding labyrinth bush, is provided with bearing sealed ring before described in the labyrinth bush, is provided with bearing gland in preceding labyrinth bush back, is provided with tapered roller bearing in the back of bearing gland.During concrete enforcement, lubricant oil is in lubricating cup joins labyrinth bush, can be lubricated roller bearing and tapered roller bearing respectively, to guarantee the normal operation of bearing, unnecessary lubricant oil can enter in the labyrinth, because the arranged outside in the labyrinth has labyrinth bush, and in labyrinth bush, be provided with bearing sealed ring again, so unnecessary lubricant oil can not leak into the outside of bearing support, thereby guarantee can not pollute, also prolonged the working life of equipment simultaneously environment.
