Abstract
The utility model relates to an improved bearing body part which comprises a bearing body, an oil baffle disc, a bearing press cover, a bearing cavity, a bearing, an oil ring, a bearing spacer sleeve, a cavity cover plate which is arranged on the end part of the bearing spacer sleeve and bearing cavity to form a sealing cavity; the bearing body is divided into the bearing cavity and the cavity cover plate, which causes the assembly and disassembly of the oil ring to be convenient and easy and to have labor saving and time saving. A gag lever post component which is used for limiting the movement position of the oil ring is arranged on the cavity cover plate, and ensures that the oil ring contacts thin oil in the bearing cavity when the oil ring rotates around a shaft, and the bearing is under an excellent lubrication state all the time. The utility model has simple and compact structure, convenient manufacture and easy use and the maintenance. The utility model is widely suitable for machines with gyratory motion, such as pumps, blower fans, steam engines, etc.
Description
Technical field
The utility model relates to the bearing support structure, particularly a kind of modified model bearing body part.
Background technique
Usually, pump, blower fan, steamer etc. are made the machinery of rotation motion, and used bearing adopts thin oil lubricant also to join disc and use together, and disc is done eccentric rotation around main shaft, make thin oil in the bearing cavity be stirred everywhere and splash.
Referring to Fig. 1, the seal arrangement that bearing body part adopted of old-fashioned structure, the thin oil seal that is difficult to splash is everywhere lived, more serious leakage takes place thus, cause thin oil deficiency in the bearing cavity, so the thin oil of must in the bearing cavity, annotating continually, this just makes the security and stability of entire pump group reduce greatly, and has caused environmental pollution.
In addition, the bearing cavity of old-fashioned structure is cumbersome when dismounting and assembling disc.Also have, contact with thin oil in the cavity all the time when the disc of old-fashioned airframe bearing body is difficult to guarantee the disc motion.
Summary of the invention
Task of the present utility model provides a kind of modified model bearing body part, it has solved the used seal arrangement of old-fashioned airframe bearing body component and has been difficult to thin oil seal is lived, leak thus, cause thin oil deficiency in the bearing cavity, and in dismounting problem such as cumbersome during with the assembling disc.
The technical solution of the utility model is as follows:
A kind of modified model bearing body part, it comprises bearing support, oil baffle disc, bearing gland, the bearing cavity, bearing, disc and bearing interstage sleeve, it also comprises the cavity cover plate of the composition seal chamber that is installed in bearing interstage sleeve and bearing bore end of body, makes bearing support be divided into bearing cavity and cavity cover plate two-part; The position-limited lever parts of placing restrictions on the disc movement position are housed on the described cavity cover plate.
The opening structure form was divided into bearing cavity and cavity cover plate two-part with bearing support before and after bearing body part of the present utility model was taked, and made that assembling and dismounting disc are easily convenient, time saving and energy saving.Bearing interstage sleeve and cavity cover plate are used, and form a seal chamber, will be got rid of to the thin oil seal of cavity cover plate direction in the cavity outside by disc, guarantee that thin oil can not enter gap between axle and the bearing cavity cover plate, thereby can not leak.Have the Oil Guide annular groove on the bearing cavity cover plate, this part thin oil is led get back in the bearing cavity.Have the labyrinth seal groove on the bearing cavity cover plate, installed rubber oil sea additional, so both prevented to turn round and cause gap between bearing interstage sleeve and the cavity cover plate to strengthen to leak out thin oil, to have prevented that again external dust and sewage from entering the bearing cavity and polluting thin oil owing to the pump group leader time.The movement position of position-limited lever component limitations disc guarantees that disc contacts with thin oil in the bearing cavity all the time, makes bearing be in good lubricating status all the time when pivoting.
This bearing body part is simple and compact for structure, makes easy to processly, and working service is convenient, is widely used in the machinery that pump, blower fan, steamer etc. are done rotation motion.
Description of drawings
Fig. 1 is the bearing body part schematic representation of old-fashioned structure.
Fig. 2 is the structural representation of a kind of modified model bearing body part of the present utility model.
Embodiment
Referring to Fig. 2, the utility model is a kind of modified model bearing body part, and it is equipped with bearing support, oil baffle disc 11, felt collar 12, bearing gland 13, bearing cavity 14, bearing 15, position-limited lever parts 16, disc 17, bearing interstage sleeve 18, cavity cover plate 19, rubber oil sea 20 and oil sealing pressing plate 21.
At bearing interstage sleeve 18 and bearing cavity 14 ends cavity cover plate 19 is installed, bearing interstage sleeve 18 and cavity cover plate 19 are used, form a seal chamber, gap between them is between 0.15～0.5mm, the thin oil that flies to the cavity cover plate that the opening direction in gap and disc have got rid of is opposite with velocity attitude in the horizontal direction, thereby this part thin oil is isolated in the cavity outside.On cavity cover plate 19, be provided with the Oil Guide annular groove, make that this part thin oil is led to get back in the bearing cavity 14, thereby cut off the possibility that thin oil leaks out from the source.
The opening structure form was divided into bearing cavity 14 and cavity cover plate 19 two-part with bearing support, so that Assembly And Disassembly disc 17 not only saves time but also laborsaving before and after this bearing body part was taked.
Position-limited lever parts 16 are housed on the cavity cover plate 19, placing restrictions on the movement position of disc 17, guarantee that disc 17 contacts with thin oil in the bearing cavity 14 all the time, makes bearing 5 be in good lubricating status all the time when pivoting.
Also be provided with the labyrinth seal groove on the cavity cover plate 19, installing rubber oil sea 20 in the seal groove is installed oil sealing pressing plate 21 on rubber oil sea 20.So both can prevent to turn round and cause gap between bearing interstage sleeve and the cavity cover plate to strengthen to leak out thin oil, can prevent that again external dust and sewage from entering the bearing cavity and polluting thin oil owing to the pump group leader time.
