Abstract
The utility model discloses a double-arc static main bearing of a ball mill, which has the advantages of simple structure, convenient use, low cost, large bearing capacity and the like and comprises abearing cover, a bearing bush, a bearing seat and a ring seal. The bearing bush is installed on the bearing seat. The bearing bush is of a double-arc structure and a ring cooling water pipe is inlaidin the bearing bush. A platinum resistance thermometer sensor is installed in the bearing bush. A lubricating device and a high-pressure oil supply jack system are arranged in a bearing.
Description
Technical field
The utility model relates to the two circular arc hydrostatic spindles of ball mill and holds, and the two circular arc hydrostatic spindles of particularly a kind of new ball mill hold.
Background technology
Small grinder adopts the spherical bush base bearing more now, and the large-size ball mill pair circular arc dynamic and static pressure base bearings that adopt are subjected to the restriction in load variations and bearing shell and diameter of axle gap with upper bearing (metal) more, not only waste steel, and the operation maintenance complexity, make and the operating cost height.
Summary of the invention
The utility model is exactly in order to address the above problem, and provides a kind of and has simple in structurely, easy to use, and the two circular arc hydrostatic spindles of ball mill of advantage such as cost is low, and bearing capacity is big hold.
For achieving the above object, the utility model adopts following technical scheme:
The two circular arc hydrostatic spindles of a kind of ball mill hold, and it comprises bearing cap, jewel, bearing block, ring packing, and jewel is placed on the bearing block; Described jewel is two arc structures, edge annular cooling water pipe in it; The also interior dress platinum resistance thermometer sensor, of jewel also is provided with lubricating arrangement and fueller in bearing simultaneously.
Described lubricating arrangement is the lubricating oil pipe that is arranged on the bearing cap bottom.
Described fueller is a high-pressure oil pipe, and it is communicated with axle journal by the oil circuit of jewel inside, plays the effect of jack-up axle journal.
When the utility model is installed grinder shell cover is installed on the grinder main bearing; bearing adopts the static pressure new technology: the lubricating oil of hydrostatic bearing is supplied with by the high-low pressure lubrication station; hydraulic oil arrives axle journal and jewel contact position through the hydraulic oil path in the jewel; and between forms oil film; make bearing of journals lining go up " being risen floating "; form full fluid friction lubricating status; all the time be in work under the static pressure oil film state in the process of moving and shutting down because coal pulverizer starts, axle journal and bearing shell have been played good protective action.Thoroughly solved the tile kilning phenomenon.
The utility model adopts two arc bearing linings.Be about to jewel and be designed to two arc structures, make its with saddle between become line to contact, improved the condition of work of base bearing, simplified regular maintenance, edge annular cooling water pipe in the jewel, the security and the reliability of base bearing have been increased, dress platinum resistance thermometer sensor, in the jewel, can carry out immediately monitoring to grinder main bearing, use dynamic and static pressure lubricating oil station to provide static pressure to support and hydrodynamic lubrication, not have wearing and tearing to help keeping for a long time the precision of equipment to prolong service life of bearing because Metal Contact can not take place on bearing two surfaces, reduced the equipment failure rate of grinding machine, and power disposes and can greatly reduce.Increase annular seal, prevented the seepage of lubricating oil.
The beneficial effects of the utility model are: the utility model simple structure, compactness, and reasonable in design, it is big that this bearing has bearing capacity, the rigidity height, starting power is little, and power consumption is highly suitable for ball mill for a short time, and cost is low, is easy to promote the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, bearing cap 2, lubricating oil pipe 3, jewel 4, platinum resistance thermometer sensor, 5, high-pressure oil pipe 6, bearing block.
