Description
Technical field:
The utility model relates to a kind of friction free Oscillating lever bearing.
Background technology:
Oscillating lever bearing is a kind of common connection bearing, be used for electric hammer and come and go saw. Common forkBearing arrangement is fixed, and a kind of Oscillating lever bearing of specification often can only be used for the electric hammer of specific standard and pastReturn in saw, cannot accomplish that plurality of specifications is general. And along with scientific and technological development, much machinery is for connecting portionThe requirement of part is also more and more higher, and traditional Oscillating lever bearing exists larger frictional force in the time rotating, for a long timeTime after easily there is the situation of excess Temperature, in the time adding lubricating oil, also cannot accomplish to add evenly, makeBecome greatly shorten the service life of Oscillating lever bearing.
Summary of the invention:
The purpose of this utility model is in order to solve the problems of the prior art, and a kind of Stability Analysis of Structures is provided, and rubsWiping power is minimum, adds lubricating oil evenly, conveniently, and the wide Novel swing rod bearing of the scope of application.
In order to achieve the above object, the technical solution of the utility model is:
A kind of friction free Oscillating lever bearing, comprises bearing core and bearing outer ring, described bearing core and bearing outer ringBetween retainer is installed, in described retainer, be movably installed with ball, described ball all with bearing core andBearing outer ring is movably connected; On described bearing outer ring, connecting rod is installed, on described connecting rod, connection is installedBall, described connection ball is movably installed with adapter sleeve outward, on described adapter sleeve, Connection Block is installed; Described bearingCore inner is movably installed with spheroid, and described spheroid and ball are also movably connected; The bilateral symmetry of described bearing coreThe first joint pin and the second joint pin are installed, and described the first joint pin is provided with on the one end away from bearing coreThreaded ends, is provided with pouring orifice on the first joint pin between described threaded ends and bearing core, instituteState the first joint pin inside and offer oiling passage, the two ends of described oiling passage respectively with pouring orifice and ballBody is connected.
Described the second joint pin offers connector on the one end away from bearing core, in described connector, offersInternal thread, is provided with rubber blanket in the connector of described female ends.
Described bearing core, the first joint pin and the second joint pin are integrated to manufacture and form.
On described threaded ends, limiting section is installed.
Described spheroid is the spheroid that corrosion resistant alloy is made.
The beneficial effects of the utility model are: a kind of friction free Oscillating lever bearing of the present utility model, bearing coreInside is provided with spheroid, and spheroid and ball are also movably connected, and makes the friction of Oscillating lever bearing generation in the time rotating moreLittle, be not prone to the situation of excess Temperature; And first offer pouring orifice and oiling passage on joint pin,Oiling passage is connected with spheroid, rotates by spheroid, and lubricating oil can evenly add on each ball, makes pendulumThe longer service life of rod bearing.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Embodiment 1
A kind of friction free Oscillating lever bearing as shown in Figure 1, comprises bearing core 1 and bearing outer ring 2, described axleHold between core 1 and bearing outer ring 2 retainer 3 be installed, in described retainer 3, be movably installed with ball 4,Described ball 4 is all movably connected with bearing core 1 and bearing outer ring 2. On described bearing outer ring 2, be provided withConnecting rod 21, is provided with on described connecting rod 21 and connects ball 22, the outer company of being movably installed with of described connection ball 22Female connector 23, is provided with Connection Block 24 on described adapter sleeve 23. Connecting ball 22 and adapter sleeve 23 can be polygonalDegree rotates, and Connection Block 24 can be connected with the fixed bar of multi-angle.
Described bearing core 1 internal activity is provided with spheroid 5, and described spheroid 5 is also movably connected with ball 4. BallBody 5 can greatly reduce bearing suffered frictional force of ball 4 in the time rotating, and coordinates lubricating oil to accomplishAlmost do not have frictional force to produce, increase the service life of bearing. The bilateral symmetry of described bearing core 1 is provided withThe first joint pin 11 and the second joint pin 12, pacify on described first joint pin 11 one end away from bearing core 1Threaded ends 13 is housed, peace on the first joint pin 11 between described threaded ends 13 and bearing core 1Pouring orifice 6 is housed, and described the first joint pin 11 inside offer oiling passage 61, described oiling passage 61Two ends be connected with pouring orifice 6 and spheroid 5 respectively. Spheroid 5 can be delivered to lubricating oil in the time rotatingOn each ball 4, lubricating oil is added evenly.
On described second joint pin 12 one end away from bearing core 1, offer connector 7, described connector 7Inside offer internal thread 71, in the connector 7 of described internal thread 71 ends, rubber blanket 72 is installed, rubberPad 72 is more enough prevents that connector 7 is when fixed bar connects to clash into. Described bearing core 1, the first connectionPost 11 and the second joint pin 12 are integrated to manufacture and form, and make Oscillating lever bearing entirety more firm. Described screw threadLimiting section 14 is installed on link 13. Spheroid that described spheroid 5 is made for corrosion resistant alloy, makes spheroid 5Longer service life.
A kind of friction free Oscillating lever bearing of the present embodiment, bearing core inside is provided with spheroid, spheroid and ballAlso be movably connected, the friction that Oscillating lever bearing is produced in the time rotating is less, is not prone to the situation of excess Temperature;And first offer pouring orifice and oiling passage on joint pin, oiling passage is connected with spheroid, passes through spheroidRotate, lubricating oil can evenly add on each ball, makes the longer service life of Oscillating lever bearing.
