Abstract
A supporting structure of an operating shaft with large axial force and a high rotary speed comprises at least two angular contact bearings, an inner bearing cover, an end cover and an outer bearing cover, wherein one end of the end cover is connected with the inner bearing cover while the other end of the end cover is connected with the outer bearing cover, the end cover, the inner bearing cover and the outer bearing cover are tightened together, a closed bearing cavity is formed between the inner bearing cover, the end cover and the outer bearing cover, the angular contact bearings are arranged in the bearing cavity and are connected in series to a motor shaft in sequence, a lubricating disc is arranged at the end part of one angular contact bearing at the top of the motor shaft, a lock nut is arranged at the end part of the lubricating disc, and the inner bearing cover is arranged at the end part of the other angular contact bearing at the bottom of the motor shaft. The utility model has simple assembly, smooth grease circulation and convenient oil drainage and oiling; the lock nut is used for fixing the inner rings of the angular contact bearings and adjusting the position gap of the angular contact bearings; and the rated rotational speed of each angular contact bearing is larger than that of a thrust bearing, thereby facilitating the improvement of the running speed of the motor shaft.
Description
Technical field
The utility model relates to a kind of class supporting construction, especially relates to the supporting construction of a kind of larger axial force and high rotation speed operation axle class.
Background technology
Existing larger axial force motor shaft mainly adopts thrust bearing, because thrust bearing can not bearing radial force, therefore, needs to cooperate a deep groove ball bearing just can bear the motor rear end radial load.But, direct assembled in series between thrust bearing and the deep groove ball bearing, the rigid bearing Internal and external cycle must be set up in the centre, like this, tends to make that the lubricating grease in the bearing bore is unfavorable for flowing, and causes bearing to refuel and the inconvenience of oil extraction.In addition, because the restriction of the rated speed of thrust bearing, it can not be applied to the state of higher rotation speed.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of oil extraction and the larger axial force easy to lubricate and the supporting construction of high rotation speed operation axle class.
The technical solution of the utility model is: it comprises at least two angular contact bearings, internal bearing cover, end cap and bearing end cover, one end of end cap links to each other with internal bearing cover, the other end of end cap links to each other with bearing end cover, end cap, internal bearing cover and bearing end cover fasten as one, internal bearing cover, form an airtight bearing bore between end cap and the bearing end cover, angular contact bearing is located in the bearing bore, each angular contact bearing is serially connected with on the motor shaft successively, the end of being located at motor shaft angular contact bearing topmost is provided with disc, the disc end is provided with locking nut, and internal bearing cover is located at the end of motor shaft angular contact bearing bottom.
Described end cap, internal bearing cover and bearing end cover fasten as one by screw.
The beneficial effects of the utility model are that each angular contact bearing is assembled in series directly, assembles simply, has reduced number of components and parts; Do not have the obstruct of other part between each angular contact bearing of series connection, the grease circulation is smooth and easy, oil extraction and easy to lubricate, and it is well lubricated to guarantee that bearing can obtain; The locking nut that the end of disc is provided with both can be used for the inner ring of fixed angles contact bearing, the position gap that can be used for regulating angular contact bearing again; The rated speed of angular contact bearing helps improving the running speed of motor shaft much larger than thrust bearing.
