Description
Technical field
The utility model relates to a kind of self-lubricating Oscillating lever bearing.
Background technology
Oscillating lever bearing is a kind of common part in reciprocating saw, it comprises bearing core, cartridge housing, be sandwiched in described inSteel ball between bearing core and cartridge housing, described steel ball is kept by retainer. But current used forkBearing exists installs inconvenience, and bonding strength is poor, simultaneously between the bearing core of Oscillating lever bearing and the cartridge housingGrease is very few or while thering is no grease, between steel ball and bearing core just in dry condition, the temperature of its frictionDegree can increase and raise along with the time of friction, and in the time of excess Temperature, it is discontinuous that steel ball will roll, evenThere will be the phenomenon of fusing, affected the normal use of electric hammer. Between bearing core and installation shaft, also exist simultaneouslyGrease is very few or while thering is no grease, between bearing core and installation shaft just in dry condition, thereby causeThe wearing and tearing of bearing core and installation shaft, also can affect the normal use of electric hammer.
Utility model content
The purpose of this utility model is to provide a kind of self-lubricating Oscillating lever bearing, and lubricated runner, lubricating oil storeThe setting of inner chamber not only can store lubricating oil, and can distinguish lubricating bearings core and cartridge housing, bearing coreWith installation shaft, improve the service life of Oscillating lever bearing.
In order to achieve the above object, the technical solution of the utility model is:
A kind of self-lubricating Oscillating lever bearing, comprises bearing core, on described bearing core, be separately installed with clutch shaft bearing shell,The second cartridge housing, is provided with the first retainer between described bearing core and clutch shaft bearing shell, and described first keepsThe first steel ball is installed in frame, between described the second cartridge housing and bearing core, the second retainer is installed, described inThe second steel ball is installed in the second retainer; In described bearing core, offer respectively lubricated runner, carry and lubricateRunner, described lubricated runner with carry installations that be connected of lubricated runner, described conveying is lubricated runner respectively with theThe installation that is connected of one drain flow path, the second drain flow path, is provided with first in wherein said the first drain flow pathSteel ball, is provided with the second steel ball in described the second drain flow path.
In described bearing core, offer installation groove, in described installation groove, offer lubricating oil and store inner chamber,Described lubricating oil stores inner chamber and lubricates the runner installation that is connected by connecting passage with carrying.
On described bearing core, offer lubricated runner inlet, described lubricated runner inlet and lubricated runner phaseBe communicated with and install, and on described lubricated runner inlet, sealing ring is installed.
Described clutch shaft bearing shell is connected with bearing core is vertical, and described the second cartridge housing tilts to be connected with bearing core.
The beneficial effects of the utility model are: a kind of self-lubricating Oscillating lever bearing, lubricated runner, lubricating oil storeThe setting of inner chamber not only can store lubricating oil, and can distinguish lubricating bearings core and cartridge housing, bearing coreWith installation shaft, improve the service life of Oscillating lever bearing.
