Abstract
A vertical motor bearing device comprises a rotary shaft, an outer bearing cover, a locking nut, an oil thrower, an oil filling pipe, an end cover, a bearing sleeve, a bearing, a circular ring, an inner bearing cover and a labyrinth ring. The end cover is welded together with the bearing sleeve; a retaining shoulder is arranged at an inner circle of the bearing sleeve; an outer bearing ring is fixed jointly by the retaining shoulder and the circular ring; an inner beating ring is fixed onto the rotary shaft by the aid of the oil thrower and the labyrinth ring; the oil thrower is fixed onto the rotary shaft by the aid of the locking but; the outer bearing cover and the inner bearing cover are respectively connected with the bearing sleeve from two sides; and the oil filling pipe is mounted on the outer bearing cover. The vertical motor bearing device can meet the use requirement of bearing large thrust without investing other equipment under the condition of not changing the assembly structure inside the bearing, and has the advantages of simple and compact structure, lower cost and high reliability.
Description
Technical field
The utility model relates to the transmission part of vertical machine, is specifically related to bearing device of vertical motor.
Background technique
At present, the huge market demand of vertical machine, economic benefit height.But vertical machine also will bear magnetic pull except that requiring the bear rotor own wt.The vertical machine of general producer adopts the angular contact ball bearing device, can't satisfy the requirement of strength.If adopt plain bearing arrangement, though thrust can be born, make motor bearings apparatus structure complexity, cost higher, install, debugging, transportation be cumbersome.
The model utility content
At the above-mentioned deficiency of existing bearing device of vertical motor, the claimant improves through research, can bear big thrust thereby provide a kind of, bearing device of vertical motor simple in structure again, that cost is low, reliability is high.
The technical solution of the utility model is as follows:
A kind of bearing device of vertical motor, comprise rotating shaft, bearing end cover, locking nut, disc, oil filler pipe, end cap, bearing housing, bearing, annulus, internal bearing cover and labyrinth ring, described end cap and bearing housing weld together, circle is provided with shoulder block in the bearing housing, described shoulder block is with annulus rigid bearing outer ring, bearing inner race is fixed in the rotating shaft by disc and labyrinth ring, disc is fixed in the rotating shaft by locking nut, bearing end cover, internal bearing cover are connected with bearing housing from both sides respectively, and oil filler pipe is installed on the bearing end cover.
Its further technological scheme is: described bearing is a single-row tapered roller bearing.
Its further technological scheme is: described oil filler pipe end is provided with thread, links together with the internal thread of bearing end cover.
Its further technological scheme is: described bearing end cover is inboard to be provided with the labyrinth with the locking nut outside.
Its further technological scheme is: the described internal bearing cover outside is provided with the labyrinth with the labyrinth ring inboard.
Useful technique effect of the present utility model is:
The utility model is simple in structure, compact, under the situation that does not change bearing mounted inside structure, does not need to drop into other equipment, can reach the usage requirement of bearing big thrust.For example adopt SKF spherical roller thrust-bearing, its dynamic load rating will reach about 1180KN, and the theoretical calculation life-span will reach about 100,000 hours, the reliability height.And this bearing structure is simple, and cost is lower, and price has only about 1/8 of plain bearing arrangement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises rotating shaft 1, bearing end cover 2, locking nut 3, disc 4, oil filler pipe 5, end cap 6, bearing housing 7, bearing 8, annulus 9, internal bearing cover 10 and labyrinth ring 11.Bearing 8 in the present embodiment is a single-row tapered roller bearing, preferably adopts SKF spherical roller thrust-bearing.End cap 6 welds together with bearing housing 7, and adding man-hour also is to weld together back fine finishing, with the concentricity of circle in the raising bearing housing 7 with end cap 6 cylindricals.Circle is provided with shoulder block 12 in the bearing housing 7, and shoulder block 12 is with annulus 9 rigid bearings 8 outer rings, and bearing 8 inner rings are fixed in the rotating shaft 1 by disc 4 and labyrinth ring 11, and disc 4 is fixed in the rotating shaft 1 by locking nut 3.Bearing end cover 2, internal bearing cover 10 are connected with bearing housing 7 from both sides respectively.Oil filler pipe 5 is installed on the bearing end cover 2.Oil filler pipe 5 ends are provided with thread, link together with the internal thread of bearing end cover 2.Bearing end cover 2 is inboard to be provided with the labyrinth with locking nut 3 outsides, prevents that dust impurity etc. from entering bearing 8 inside, improves security level.Internal bearing cover 10 outsides and labyrinth ring 11 inboards are provided with the labyrinth, prevent that lubricant oil from entering motor internal, improve security level.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection domain of the present utility model.
