The utility model relates to a vertical motor bearing device, which is characterized in that an oil box is provided with a lower bearing seat and a sleeve; the top of the oil box is provided with a cover plate; a bearing sleeve is arranged below the oil box, a roller bearing is installed inside the bearing sleeve, and two ends of the bearing sleeve are provided with a bearing inner cover and an upper bearing cover; a skeleton oil tight is installed inside the bearing inner cover; the outer circle of a spherical roller thrusting bearing is matched with the lower bearing seat, and an inner ring is matched with an upper bearing seat; and a motor rotating shaft is locked by a round nut and a stop gasket ring after being matched with an inner hole of the upper bearing seat. The vertical motor bearing device has compact and reasonable structure and adopts thin oil to lubricate; the rating dynamic load of the SKF spherical roller thrusting bearing reaches 1180 KN, and the theoretical service life when bearing the thrusting force of 8T can reach 100 thousand hours. Moreover, the bearing structure is simple, and the cost is low and is only one eighth of that of a gap block device.

Description

Bearing device of vertical motor
Technical field
The utility model relates to a kind of vertical machine rolling bearing system of high thrust thin oil lubricant, specifically aim at the bearing arrangement that some bear the vertical machine thin oil lubricant of the following thrust of 8T, it belongs to the transmission component of a key of high thrust vertical machine.
Background technology
At present, the supporting motor of more domestic big water pumps also need bear the following thrust of 8T except that requiring the bear rotor deadweight.General vertical machine is all used angular contact ball bearing, but can't bear so high thrust.If adopt the bearing shell device of thin oil lubricant, though thrust can be born, complex structure, cost are very high, Installation and Debugging, transportation are also pretty troublesome.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, can bear the following thrust of 8T thereby provide a kind of, vertical machine rolling bearing system simple in structure, that cost is low, reliability is high.
According to the technical scheme that the utility model provides, a kind of bearing device of vertical motor comprises machine shaft, and feature is: step and sleeve are installed on the fuel tank; The fuel tank top is gone up cover plate is installed; Roller bearing is installed in the installation shaft bearing sleeve under the fuel tank, bearing holder (housing, cover), and internal bearing cover, upper ball cover are installed in the bearing holder (housing, cover) two ends; Outside framework oil seal is installed in the internal bearing cover; Spherical roller thrust bearing cylindrical cooperates with step, and inner ring cooperates with top chock; Machine shaft cooperates the back to lock with round nut, stop washer with the endoporus of top chock.
Be provided with the reservoir compartment in the described internal bearing cover.Described upper ball cover is provided with refueling device.
On the described cover plate respirator is installed.On the described fuel tank oil ga(u)ge is installed.
On the described fuel tank plug is installed.On the described fuel tank fin is set.Contain thin oil in the described fuel tank.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, has rationally adopted thin oil lubricant, and the dynamic load rating of SKF spherical roller thrust bearing will reach about 1180KN, and the Theoretical Calculation life-span when bearing the following thrust of 8T will reach about 100,000 hours.And this bearing arrangement is simple, and cost is lower, has only about 1/8 of bearing shell device.
