Abstract
The utility model relates to a vertical-type motor air-to-air cooling thrust bearing device, wherein a thrust bearing is installed on a motor shaft, a radial fan or an axial-flow fan is installed on the motor shaft, and radiating ribs and an air-guiding structure are positioned on the outer surface of a thrust bearing oil box. With the vertical-type motor air-to-air cooling thrust bearing device, the problems that an oil-water cooler and cooling-water source must be installed in a thrust bearing device and the natural cooling capability of bearing oil box surface is deficient are resolved, and the self-radiating property of the thrust bearing is improved, therefore, the vertical-type motor of the utility model can run normally even if no cooling-water source exists.
Description
Technical field
The utility model relates to a kind of motor bearings cooling device, relates in particular to a kind of vertical machine sky-empty cooling type thrust bearing device.
Background technology
Existing vertical machine thrust box surface natural heat dissipation ability is low, so in the bearing fuel tank, must have oil-water cooler, and cooling water water source, bearing the bearing temperature rise that produces behind axial load and the radial load to reduce thrust bearing, the temperature rise of bearing in allowed limits when guaranteeing the motor operation.But oil-water cooler complex structure, and will consume a large amount of cooling waters does not possess the place of cooling water source at its periphery, and motor just can not normally move use.
The utility model content
The purpose of this utility model is to provide a kind of vertical machine sky simple in structure-empty cooling type thrust bearing device, does not possess the place of cooling water source to guarantee periphery, and vertical machine also can normally move use.
The technical solution of the utility model is: thrust bearing is installed on the motor shaft, and radial fan or tube-axial fan are installed on the described motor shaft.
Below be preferred version:
Thrust bearing fuel tank appearance also is provided with radiating ribs or/and air guide structure.
Described thrust bearing is the spherical roller thrust bearing.
The utility model is owing to be equipped with radial fan or tube-axial fan on motor shaft, be provided with radiating ribs or/and air guide structure at bearing fuel tank outer surface, efficiently solve and to have oil-water cooler and cooling water water source thereof, bearing housing surface natural heat dissipation ability shortcoming problem in the thrust bearing device, improved thrust bearing self-radiating performance, thereby, even in the place that does not possess cooling water source, adopt vertical machine of the present utility model also can normally move.
