Abstract
The utility model belongs to sliding bearing technical field, more particularly to a kind of bearing shell, including bearing shell ontology and throttling screw plug, the bearing shell ontology is made of two semicircular rings, crescent oil groove is arranged in inner hole at two semicircular ring combined face, oil groove bottom surface sets fuel feed hole, and end face is equipped with threaded hole and communicates with the crescent oil groove of inner hole；The throttling screw plug is columnar component, and end face is equipped with throttling through-hole, and outer circle is equipped with external screw thread and sleeve body end-face helical hole matches.By setting throttling screw plug in bearing shell ontology end face, the metallic particles for generating the sandy environment for entering oil groove in lubricating oil and abrasion is discharged by throttle orifice, fuel reserve tank is come back to be filtered, avoid the accumulation of foreign matter, reduce so that being worn between bearing shell and shaft, meanwhile, pass through the adjustment to throttle orifice, it can be effectively controlled flow of lubrication and input pressure, increase bearing shell service life.
Description
Technical field
The utility model belongs to sliding bearing technical field more particularly to a kind of bearing shell.
Background technique
Bearing shell is the critical component of sliding bearing, is the part with shaft contacts, is generally made of two semicircular rings, and
Crescent oil groove is arranged in inner hole at two semicircular ring combined face, and oil groove bottom surface sets fuel feed hole, and main function is: carrying the diameter of shaft
To load, oil-film stabilization is kept, reduces the abrasion of shaft and bearing shell.Due to existing part sliding bearing unit working environment ratio
It is relatively severe, such as cement plant, dust pollution is more serious, and the particulate matters such as dust easily pass through lubrication oil supply system and enter bearing shell
Inner hole, and the gap of bearing shell and shaft is smaller, can not be discharged, and is trapped in oil groove, and the abrasion of bearing shell is not only caused to aggravate, simultaneously
Also the rigidity that oil film can be destroyed, makes bearing lubrication fail, and influences unit normal operation.
Summary of the invention
The utility model is to provide a kind of bearing shell to solve the above-mentioned problems.
The embodiment of the utility model is achieved in that a kind of bearing shell, including bearing shell ontology and throttling screw plug, feature exist
In: the bearing shell ontology is made of two semicircular rings, and crescent oil groove is arranged in inner hole at two semicircular ring combined face, and oil groove bottom surface is set
Fuel feed hole, end face are equipped with threaded hole and communicate with the crescent oil groove of inner hole；The throttling screw plug is columnar component, and end face is equipped with
Throttle through-hole, and outer circle is equipped with external screw thread and sleeve body end-face helical hole matches.
The beneficial effects of the utility model are: through the above scheme, setting throttling screw plug in bearing shell ontology end face, making lubricating oil
The interior metallic particles generated into the sandy environment of oil groove and abrasion is discharged by throttle orifice, is come back to fuel reserve tank and was carried out
Filter, avoids the accumulation of foreign matter, reduces so that wearing between bearing shell and shaft, meanwhile, by the adjustment to throttle orifice, can effectively control
Flow of lubrication and input pressure processed increase bearing shell service life.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Fig. 2 is A-A cross-sectional view in Fig. 1.
In figure: 1, bearing shell ontology, 2, crescent oil groove, 3, fuel feed hole, 4, throttling screw plug.
Specific embodiment
Below in conjunction with attached drawing, the technical solution of the utility model is further described:
A kind of bearing shell as shown in Fig.1 and Fig.2, including bearing shell ontology 1 and throttling screw plug 4, bearing shell ontology 1 is by two semicircles
Ring composition, inner hole is arranged crescent oil groove 2 at two semicircular ring combined face, and oil groove bottom surface sets fuel feed hole 3, end face be equipped with threaded hole with
The crescent oil groove of inner hole communicates, and throttling screw plug 4 is equipped in the threaded hole, and the throttling screw plug 4 is columnar component, end face
Equipped with throttling through-hole, outer circle is equipped with external screw thread.Due to setting throttling screw plug in bearing shell ontology end face, so that entering oil groove in lubricating oil
Sandy environment and abrasion generate metallic particles by throttle orifice discharge, come back to fuel reserve tank and be filtered, avoid
The accumulation of foreign matter reduces so that wearing between bearing shell and shaft, meanwhile, the setting for the screw plug that throttles effectively controls flow of lubrication
And oil inlet pressure, it can be promoted bearing shell, increase service life.
Claims (2)
1. a kind of bearing shell, including bearing shell ontology and throttling screw plug, it is characterised in that: the bearing shell ontology is by two semicircular ring groups
