Description
Technical field
The utility model relates to a kind of Novel swing rod 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 Novel swing rod bearing, good airproof performance, lubricated runner, profitThe setting that lubricating oil stores inner chamber not only can store lubricating oil, and can distinguish lubricating bearings core and cartridge housing,Bearing core and installation shaft, the service life of improving Oscillating lever bearing.
In order to achieve the above object, the technical solution of the utility model is:
A kind of Novel swing rod 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; Described the second retainer is socketed with dust ring outward,Between described the second retainer and dust ring, glue ring is installed.
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.
In described installation groove, scuff-resistant coating 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 Novel swing rod bearing, good airproof performance, lubricated runner, profitThe setting that lubricating oil stores inner chamber not only can store lubricating oil, and can distinguish lubricating bearings core and cartridge housing,Bearing core and installation shaft, the service life of improving Oscillating lever bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
A Novel swing rod bearing as shown in Figure 1, comprises bearing core 1, on described bearing core 1, is separately installed withClutch shaft bearing shell 2, the second cartridge housing 3, be provided with the first guarantor between described bearing core 1 and clutch shaft bearing shell 2Hold frame 4, in described the first retainer 4, the first steel ball 5 is installed, described the second cartridge housing 3 and bearing core 1Between the second retainer 6 is installed, in described the second retainer 6, the second steel ball 7 is installed; Described bearing core1 interior lubricated runner 11, the lubricated runner 12 of conveying, the described lubricated runner 11 and conveying lubrication flow of offering respectivelyRoad 12 installation that is connected, the lubricated runner 12 of described conveying respectively with the first drain flow path 13, the second drainage streamRoad 14 installation that is connected, is provided with the first steel ball 5 in wherein said the first drain flow path 13, and described second drawsIn stream runner 14, the second steel ball 7 is installed; The outer dust ring 21 that is socketed with of described the second retainer 6, described theBetween two retainers 6 and dust ring 21, glue ring 22 is installed. The setting of dust ring 21 can effectively avoidTwo retainer 6 dust stratifications, the setting of glue ring 22 can ensure close between the second retainer 6 and dust ring 21Feng Xing.
In described bearing core 1, offer groove 8 is installed, in described installation groove 8, offer in lubricating oil storageChamber 9, described lubricating oil stores inner chamber 9 and lubricates runner 12 installation that is connected by connecting passage 15 with carrying.
In described installation groove 8, scuff-resistant coating 23 is installed. The setting of scuff-resistant coating 23 can avoid bearing core 1 withFrictionally damage between installation shaft.
Described clutch shaft bearing shell 2 is connected with bearing core 1 is vertical, and described the second cartridge housing 3 inclines with bearing core 1Monoclinic phase connects.
A kind of Novel swing rod bearing of the present embodiment, good airproof performance, lubricated runner, lubricating oil storage inner chamberSetting not only can store lubricating oil, and can distinguish lubricating bearings core and cartridge housing, bearing core and installationAxle, the service life of improving Oscillating lever bearing.
