Model utility content
The utility model is for the defect existing for the one-sided cantilever support of background technique middle (center) bearing support device, provides the bearing support assembly of a kind of good sealing effect, bilateral cantilever support.
The technological scheme realizing above-mentioned purpose employing is: a kind of bearing support assembly, comprise sealed interface, sealing cover, bearing and bearing support, sealed interface comprises assembly welding upper flange together, steel pipe, lower flange and spindle nose, sealing cover is sleeved in the middle part of spindle nose, spindle nose bottom and bearing housing are fitted together, and bearing is arranged on bearing support inside;
Described lower flange and sealing cover are linked together by link, and lower flange is evenly equipped with through hole along spindle nose excircle; In the middle part of spindle nose, excircle is also set with wear-resistant sleeve and lip-type packing;
Described bearing support excircle is connected with hanger, and strut is linked together by connection part and hanger, and the other end of strut is set with adpting flange, and butterfly spring is also equipped with in the strut end of adpting flange both sides.
Sealing cover upper surface is provided with an annular boss, and lower flange lower surface is provided with an annular groove matched with this annular boss, and the two plug-in mounting connects.
Wear-resistant sleeve and lip-type packing are sleeved on the excircle in the middle part of spindle nose successively, and are closely arranged on the inner side of sealing cover.
Bearing housing is contained in the bottom of spindle nose, and spindle nose bottom is provided with an axle head gland by link.
Compared with prior art, this bearing support assembly structure disclosed in the utility model is simple, and good sealing effect, compact structure, realize many fulcrum supports by the multiple struts on bearing support excircle, run stability is high.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of sealed interface.
In figure: sealed interface 1, sealing cover 2, bearing 3, bearing support 4, wear-resistant sleeve 5, axle head gland 6, supporting member 7, connecting screw rod 8, strut 9, adpting flange 10, butterfly spring 11, lip-type packing 12, upper flange 13, steel pipe 14, lower flange 15, hanger 16, spindle nose 17, through hole 18.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
See accompanying drawing 1-2, this bearing support assembly disclosed in the utility model, comprises sealed interface 1, sealing cover 2, bearing 3 and bearing support 4, and sealed interface 1 comprises assembly welding upper flange 13 together, steel pipe 14, lower flange 15 and spindle nose 17.Bearing is arranged on bearing support inside, and this bearing is deep groove ball bearing, and its outer ring is contained in the inner side of bearing support 4, and the inner ring of bearing is sleeved on the bottom of spindle nose.
Lower flange 15 and sealing cover 2 are linked together by countersunk screw, and lower flange 15 is evenly equipped with through hole 18 along spindle nose 17 excircle, and best number of through-holes is 16.Through hole is communicated with steel pipe 14, then with grinding machine ft connection.Upper flange 13 and the Flange joint on the cage rotor of grinding machine.Sealing cover 2 is sleeved on the middle part of spindle nose 17, and sealing cover 2 upper surface is provided with an annular boss, and lower flange lower surface is provided with an annular groove matched with this annular boss, and the two plug-in mounting connects.There is circular hole at annular groove center, ensures that through hole 18 and annular groove are through.Sealing cover is also provided with zigzag fashion boss inside center hole, and lip-type packing is arranged on below this zigzag fashion boss, and fits tightly with it.It is outside that lip-type packing is closely sleeved on wear-resistant sleeve 5.Wear-resistant sleeve is sleeved on the middle part of spindle nose, has positioning action.
Bearing support 4 excircle is connected with hanger 16, it is four that the best arranges number, namely be uniformly distributed along the circumference on bearing support excircle, strut 9 is linked together with hanger respectively by connection part, the other end of strut 9 is set with adpting flange 10, and butterfly spring 11 is also equipped with in the strut end of adpting flange 10 both sides.Connection part comprises the supporting member 7 hinged with hanger, also comprises the connecting screw rod 8 connecting supporting member and strut.Four groups of adpting flanges 10 are bolted on the shell flange pipe in the middle part of grinding machine.
Bearing 3 is sleeved on the bottom of spindle nose 12, and spindle nose bottom is provided with an axle head gland 6 by bolt, and this axle head gland 6 is compressed on the bottom surface of bearing.
Mechanical seal clearance is formed after sealed interface and sealing cover assemble, due to the through hole on the lower flange of sealed interface and grinding machine ft connection, and be negative pressure in grinding machine, be less than grinding machine outside atmospheric pressure, outside air can enter grinding machine inside by through hole and the gap between sealed interface and sealing cover, blown away by dust, dust can not enter bearing.Lip-type packing on sealing cover and wear-resistant sleeve form static and dynamic sealing, stuffing box bearing common with mechanical seal, dual dustproof construction, available protecting bearing.
As preferred way, bearing support arranges oil inlet hole, oil drainage hole and temperature measuring hole, lead to grinding machine shell outside by turnover oil pipe and thermometric thermal resistor, grease can be supplemented in time and discharge waste oil, and bearing temperature can be detected in time.
