Description
Technical field
The utility model relates to a kind of high sealing Oscillating lever bearing.
Background technique
Oscillating lever bearing is a kind of common part in reciprocating saw, and it comprises bearing core, cartridge housing, is sandwiched in steel ball between described bearing core and cartridge housing, and described steel ball is kept by retainer.But current used Oscillating lever bearing exists installs inconvenience, and join strength is poor, grease simultaneously between the bearing core and cartridge housing of Oscillating lever bearing is very few or when not having a grease, just dry condition is between steel ball and bearing core, the temperature of its friction can increase along with the time of friction and raise, and when temperature is too high, steel ball will roll discontinuous, even there will be the phenomenon of fusing, have impact on the normal use of electric hammer.Also exist between bearing core and installation shaft simultaneously grease very few or there is no a grease time, be just in dry condition between bearing core and installation shaft, thus cause the wearing and tearing of bearing core and installation shaft, also can affect the normal use of electric hammer.
Model utility content
The purpose of this utility model is to provide a kind of high sealing Oscillating lever bearing, good airproof performance, the setting that lubrication runner, lubricant oil store inner chamber can not only store lubricant oil, and can distinguish lubricating bearings core and cartridge housing, bearing core and installation shaft, improve the working life of Oscillating lever bearing.
In order to achieve the above object, the technical solution of the utility model is:
A kind of high sealing Oscillating lever bearing, comprise bearing core, described bearing core is separately installed with clutch shaft bearing shell, the second cartridge housing, first retainer is installed between described bearing core and clutch shaft bearing shell, in described first retainer, the first steel ball is installed, between described second cartridge housing and bearing core, the second retainer is installed, in described second retainer, the second steel ball is installed; Lubrication runner, conveying lubrication runner is offered respectively in described bearing core, described lubrication runner and conveying are lubricated runner and are connected and install, described conveying lubrication runner is connected with the first drain flow path, the second drain flow path respectively and installs, in wherein said first drain flow path, the first steel ball is installed, in described second drain flow path, the second steel ball is installed; Described bearing core offers keyway.
Offer installation groove in described bearing core, offer lubricant oil and store inner chamber in described installation groove, described lubricant oil stores inner chamber and is lubricated runner by connecting passage and be connected and install with carrying.
The arc elevator bar of more than 1 is installed in described installation groove, between adjacent two described arc elevator bars, sealing layer is installed, and described sealing layer is connected with bearing core.
Described clutch shaft bearing shell is connected with bearing core is vertical, and described second cartridge housing tilts to be connected with bearing core.
The beneficial effects of the utility model are: a kind of high sealing Oscillating lever bearing, good airproof performance, the setting that lubrication runner, lubricant oil store inner chamber can not only store lubricant oil, and can distinguish lubricating bearings core and cartridge housing, bearing core and installation shaft, improve the working life of Oscillating lever bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of high sealing Oscillating lever bearing as shown in Figure 1, comprise bearing core 1, described bearing core 1 is separately installed with clutch shaft bearing shell 2, second cartridge housing 3, first retainer 4 is installed between described bearing core 1 and clutch shaft bearing shell 2, in described first retainer 4, first steel ball 5 is installed, between described second cartridge housing 3 and bearing core 1, second retainer 6 is installed, in described second retainer 6, second steel ball 7 is installed; Lubrication runner 11, conveying lubrication runner 12 is offered respectively in described bearing core 1, described lubrication runner 11 and conveying are lubricated runner 12 and are connected and install, described conveying lubrication runner 12 is connected with the first drain flow path 13, second drain flow path 14 respectively and installs, in wherein said first drain flow path 13, first steel ball 5 is installed, in described second drain flow path 14, second steel ball 7 is installed; Described bearing core 1 offers keyway 18.The setting of keyway 18 is used for fitting key, is convenient to the installation of Oscillating lever bearing with transmitting torque.
