Abstract
The utility model discloses a main bearing of ball mill and comprises bearing cover, bearing liner and bearing seat, the bearing seat is saddle form, the axial and radial contact surfaces of bearing liner and bearing seat are circular form, the semidiameter of two circulars are inequality, the contact of bearing liner and bearing seat is line contact. The utility model has the advantages of improving working conditions of main bearing, simplifying daily maintenance work, and improving working safety and reliability with simple and compact structure, rational design, low costs of production and operation, so the utility model is especially suitable for mini type ball mill.
Description
(1) technical field
The utility model relates to a kind of bearing, particularly a kind of main bearing of ball grinding mill.
(2) background technique
Small grinder adopts the spherical bush main bearing more now, not only wastes steel, and the operation maintenance complexity, makes and the operating cost height.
(3) summary of the invention
The technical problems to be solved in the utility model is: a kind of operation maintenance that is easy to is provided, makes and the low main bearing of ball grinding mill of operating cost.
In order to solve the problems of the technologies described above, the utility model comprises bearing cap, bearing bush and bearing support, and described bearing support is a saddle-shaped, the surface of contact of described bearing bush and bearing support axially with radially be circular arc, the radius of two circular arcs does not wait, and bearing bush is the line contact with contacting of bearing support.
In order to improve Security of the present utility model and reliability, be provided with high-pressure oil pipe, water-cooling tube and platinum thermoresistance in the described bearing bush, platinum thermoresistance links to each other with the pebble mill real-time monitoring system, described bearing cap is provided with lubricant pipe, is provided with seal ring in the both sides of bearing cap inner bearing lining.
The beneficial effects of the utility model are: the utility model has improved the operating conditions of main bearing, has simplified regular maintenance, has improved the Security and the reliability of work, and simple structure, compactness, reasonable in design, manufacturing and operating cost are low, are highly suitable for small grinder.
(4) description of drawings
Accompanying drawing is the utility model structural representation;
As figure: 1, bearing cap, 2, lubricant pipe, 3, seal ring, 4, bearing bush, 5, platinum thermoresistance, 6, high-pressure oil pipe, 7, bearing support.
(5) embodiment
A kind of specific embodiment as shown in the figure, it comprises bearing cap 1, bearing bush 5 and bearing support 8, the surface of contact of described bearing bush 5 and bearing support 8 axially with radially be circular arc, the radius of two circular arcs does not wait, form an ellipsoidal surface, described bearing support 8 is a saddle-shaped, and bearing support 8 is the cylndrical surface with the surface of contact of bearing bush 5, thereby makes that bearing bush 5 and contacting of bearing support 8 are the line contact.Be provided with high-pressure oil pipe 7, water-cooling tube 4 and platinum thermoresistance 6 in bearing bush 5, described bearing cap 1 is provided with lubricant pipe 2, is provided with seal ring 3 in the both sides of bearing cap 1 inner bearing lining 5.
During installation; lubricant pipe 2 is linked to each other with dynamic and static pressure lubricating oil station; platinum thermoresistance 6 is linked to each other with the pebble mill real-time monitoring system; water-cooling tube 4 is access to the cooling water system; the diameter of axle of grinding machine is installed on the grinder main bearing; lubricant oil is supplied with by the high low pressure lubrication station; high pressure oil enters the oil pocket of the bearing shell of bearing bush 5 through bearing support 8; between axle journal and bearing shell, form oil film; make axle journal on bearing shell, " be risen floating "; form full liquid friction lubricating status, solved when coal pulverizer starts and shut down because axial tension the pulling that the cold and hot distortion of cylindrical shell causes to bearing shell.Axle journal and bearing shell have been played good protective action.Efficiently solve the tile kilning phenomenon.
