Background technology
Pendulum stone roller machine yaw is the vitals of pendulum stone roller machine, and external pendulum grinds the machine technology comparative maturity, uses also early, and domestic just have producer at design pendulum stone roller machine since the phase early 1980s, is mainly used in the processing of automobile axle shaft blank.During the work of pendulum stone roller machine, yaw bears huge axial force and radial load, and yaw is connected with mould simultaneously, the high temperature of blank is delivered on the yaw by mould, bearing lubrication to yaw impacts, and reduces the service life of bearing greatly, and the selection of bearing is very crucial.The pendulum of domestic production at present grinds the machine yaw; the shaft part of power transmission shaft adopt with housing between adopt two cylinder roller bearings to be connected with a plain thrust bearing; the flange position of power transmission shaft adopt with housing between adopt the 29360E bearing to be connected, structure is loaded down with trivial details, selecting for use of bearing is less than normal; bearing damages easily; service life is shorter, must often shut down and change bearing, influences manufacturing schedule; the bearing price is also very expensive, increases the machine upkeep expense.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of pendulum and grind the machine yaw, the shaft part of power transmission shaft adopts self-aligning roller bearing to be connected with housing, and the flange position of power transmission shaft is connected with housing by self-aligning thrust roller bearing, improve the bearing capacity of bearing, prolong the service life of bearing.
The present invention realizes with following technical scheme: a kind of pendulum grinds the machine yaw, and it is made up of housing and power transmission shaft two parts; Described housing one end is installed on the oblique ring flange of pendulum stone roller mechanomotive force power transmission shaft by stud; Pendulum grinds mould is installed in power transmission shaft by gland outer end; Described power transmission shaft is flanged (FLGD) cylinder, and the flange position of power transmission shaft is connected with housing by the bearing III; The thin shaft part of power transmission shaft is connected with housing with the bearing II by the bearing I, installs back-up ring additional between bearing I and the bearing II inner ring, and end cap is installed in the inner end of power transmission shaft by screw, and end cap compresses the inner ring of inner ring, back-up ring and the bearing II of bearing I; It is characterized in that: described bearing III is a self-aligning thrust roller bearing; Described bearing and bearing II are self-aligning roller bearing.
The sealing ring I is installed in end that described housing matches with the flange of power transmission shaft, and flange is installed in the end of power transmission shaft by screw, and flange compresses the sealing ring I.
Described housing, the stop portion that is connected with pendulum stone roller mechanomotive force power transmission shaft are installed the sealing ring II.
Good effect of the present invention is:
1, the shaft part of power transmission shaft adopts two self-aligning roller bearings to be connected with housing, and is rational in infrastructure, and installation, convenient disassembly are quick.
2, the flange position of power transmission shaft is connected with housing by self-aligning thrust roller bearing, the bearing intensity height, and bearing capacity is big, and is not fragile, reduces fault power time, increases work efficiency, and reduces maintenance cost.
3, sealing ring is installed at the casing two ends respectively, avoids lubricating oil to leak, and guarantees that bearing lubrication is good, prolongs bearing service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
Among the figure: 1, end cap, 2, stud, 3, the bearing I, 4, back-up ring, 5, the bearing II, 6, the bearing III, 7, housing, 8, the sealing ring I, 9, flange, 10, power transmission shaft, 11, gland, 12, the sealing ring II.
The specific embodiment mode
As shown in Figure 1 and Figure 2: a kind of pendulum grinds the machine yaw, and it is made up of housing 7 and power transmission shaft 10 two parts; Described housing 7 one ends are installed on the oblique ring flange of pendulum stone roller mechanomotive force power transmission shaft by stud 2; Pendulum grinds mould is installed in power transmission shaft 10 by gland 11 outer end; Described power transmission shaft 10 is flanged (FLGD) cylinder, and the flange position of power transmission shaft 10 is connected with housing 7 by bearing III 6; The thin shaft part of power transmission shaft 10 is connected with housing 7 with bearing II 5 by bearing I 3, install back-up ring 4 additional between bearing I 3 and bearing II 5 inner rings, end cap 1 is installed in the inner end of power transmission shaft 10 by screw, and end cap 1 compresses the inner ring of inner ring, back-up ring 4 and the bearing II 5 of bearing I 3; It is characterized in that: described bearing III 6 is self-aligning thrust roller bearing; Described bearing I 3 and bearing II 5 are self-aligning roller bearing.
In the present embodiment, bearing III 6 is selected the GB5859-94 self-aligning thrust roller bearing for use, and its appearance and size is: D=520mm, d=280mm, T=145mm.And inherent technology adopts the 29360E bearing, and its appearance and size is: D=480mm, d=300mm, T=109.Bearing size obviously strengthens, the bearing intensity height, and bearing capacity is big, and is not fragile, reduces fault power time, increases work efficiency, and reduces maintenance cost.
