Description
Technical field
The present invention relates to a kind of bearing bush structures, more particularly, to a kind of bearing bush structure for ball mill, belong to metallurgical life
Produce equipment design repair manufacturing technology field.
Background technology
Equipment of the dry ball abbreviation ball mill for industries first choices such as mine, chemical industry and metallurgy.This ball mill is horizontal
Tubular rotating device is made of, transmission system feed end, revolving body, discharge end, transmission system and hydraulic system major part
Include automatically controlled, motor, speed reducer, small tooth punching, big tooth punching wheel etc. again, hydraulic system includes hydraulic station, lubricating arrangement etc. again.Dry type
Ball mill have many advantages, such as it is easy to operate, operate steadily, be continuity conveying, simple in structure and easy to repair, therefore be widely used in
Need the different areas of activity ground.The Starting mode of ball mill is first to start hydraulic pump, and one layer is formed between hollow shaft and bearing shell
After oil film, so restart motor and drive entire barrel body rotation grinding mineral.In ball mill operational process, hydraulic pump can be often encountered
After startup, hydraulic oil does not flow back and bearing oil-groove is overflowed between bearing shell and hollow shaft, the situation for making ball mill that can not operate,
Not only make production that can not carry out, waste a large amount of hydraulic oil.It has been observed that hydraulic oil overflow is caused to go out bearing oil-groove
The reason is that the seal failure in bearing oil-groove, reflux line is plugged so as to cause a large amount of slag and dust.
The sealing of ball grinder bush oil groove uses the i.e. interior trim ring of two annular pressing rings and external pressure using in the outside of oil groove
Circle, inner ring are welded on tank body, and outer ring is fixed using bolt with inner ring, is carried out between annular pressing ring using wool felt
Sealing, to realize the purpose of bearing oil-groove sealing.It finds in process of production, wool felt must be carried out with the hollow shaft of ball mill
Closely contact can be only achieved the preferable sealing effect of oil groove, and hollow shaft is revolved in process of production with 24 revs/min of speed
Turn, the friction of wool felt and hollow shaft can cause its sealing performance to reduce quickly, so as to be formed between wool felt and hollow shaft
Larger gap, a large amount of slag and dust enter oil groove by gap, reflux line are caused to block.Bearing oil-groove needs after blocking
The slag and dust in oil groove are cleared up in time, and observes the degree of wear of the sealing of wool felt, replace wool felt in time.Due to
Bearing oil-groove narrow space clears up foreign matter and takes very long and be not easily cleaned totally, and the replacement of wool felt is excessively frequent every time,
The waste of a large amount of man power and materials is not only caused, very big influence also is caused to production.
