Bar, is used for limiting ball and slips from notch position, the two ends of shelves bar along the length direction of storage tank extend to in storage tank
Sidewall is fixed.
The position that described shelves bar is positioned at corresponding to the less one end of storage tank groove depth is provided with a breach, for inserting appearance for ball
Put in groove.
The upper surface of bearing body is positioned at center indent and forms center oil groove, the Shang Yan center, upper surface of bearing body
The seed oil groove being provided at circumferentially spaced multiple sector of oil groove, is provided with oil supplying hole in described bearing body, for backbone oil
Groove fluid, the sidewall of each seed oil Cao Jin center oil groove is respectively equipped with oil groove, the described seed oil groove excessively connected with center oil groove
Bottom land on be respectively equipped with the first oilhole and the second oilhole along the end positions corresponding to the circumference of bearing body, in bearing body
Position corresponding to each seed oil groove place is respectively provided with the first oilhole corresponding to the respective seed oil groove of connection and the second oilhole
Connection oil circuit.
Being provided with the transition oil groove of an annular between the oil groove of described seed oil Cao He center, each seed oil groove is respectively by respective mistake
Oil groove connects with transition oil groove, in the fluid overflow in the oil groove of center to transition oil groove.
On the medial wall of described center oil groove, nearly bottom land position is provided with one and crosses oil inclined hole, and described crosses oil inclined hole along level side
To being downwardly inclined extension, with connection transition oil groove and center oil groove.
The described aperture crossing oil oil groove position, inclined hole nearly center is less than and crosses oil position, inclined hole nearly transition oil groove place
The aperture put.
The shape of cross section of described center oil groove is circular, and the diameter of the bottom land position of described center oil groove is more than center
The diameter of oil groove notch position.
Described transition oil groove is built into the filter body of at least one porous, and described filter body is spherical structure.
After using above structure, first a kind of double face abrading machine of the present invention compared with prior art has the advantage that, drives
Dynamic device drives upper millstone to rotate, and upper millstone is by the frictional force between the frictional force between workpiece and workpiece and lower millstone
Drive lower millstone rotates, and therefore it i.e. can be under the effect of inertia of lower millstone, it is achieved relative between upper millstone and lower millstone
Rotate and grinding work piece, simultaneously will not cause workpiece fragmentation due to upper millstone at the bigger active force of initial start stage the most again, secondly,
By storage tank and the design of ball, making bearing body easy for installation, its unloading process is the easiest simultaneously, and finally, lower millstone turns
Time dynamic, form oil lamella between lower millstone and bearing body, thus avoid in lower millstone rotation process and firmly connect with bearing body
Touching, therefore frictional force is little, it is little to shake, lower millstone stability of rotation, and simultaneously without arranging rolling element, therefore manufacturing cost reduces.
