Abstract
The invention discloses a hybrid bearing combined with a shallow cavity. The hybrid bearing comprises an outer shaft. An oil injection hole is formed in the outer side of a first rotating shaft and located in one side of the body of the cavity. A second rotating shaft is connected to the inner wall of the first rotating shaft in a sleeved mode. The inner wall of the first rotating shaft is evenly provided with grooves. The outer side of the second rotating shaft is evenly provided with pin rollers matched with the grooves. An inner shaft is connected to the inner wall of the second rotating shaft in a sleeved mode. The inner wall of the second rotating shaft is provided with a limiting groove. The outer side of the inner shaft is provided with a protruding block matched with the limiting groove. According to the hybrid bearing combined with the shallow cavity, friction between bearings is effectively reduced, and preparing work before working is avoided; compared with common equipment, the efficiency is improved, time waste is avoided, the service life of the hybrid bearing is ensured, the hybrid bearing can be used for a longer time, much money can be saved for factories with large consumption after a long time, and the hybrid bearing is worthy of popularization in the future.
Description
Technical field
The present invention relates to dynamic and hydrostatic bearing technical field, be specially a kind of dynamic and hydrostatic bearing of shallow chamber combination.
Background technique
Dynamic and hydrostatic bearing is can under hydrostatic lubrication state, the sliding bearing that can work under hydrodynamic lubrication state again, the sliding bearing simultaneously worked under hydrostatic lubrication and hydrodynamic lubrication, carry out under the existing state risen at static pressure oil float at main shaft, damage main shaft and dynamic and hydrostatic bearing like this.Before also needing work, spended time removes to observe pump station pressure and bistrique static pressure whether in regulating scope, loses time just to lower efficiency, because existing frictional force is too large, be easy to cause damage to this, working life is too short, and for this reason, we propose a kind of dynamic and hydrostatic bearing of shallow chamber combination.
Summary of the invention
The object of the present invention is to provide a kind of dynamic and hydrostatic bearing of shallow chamber combination, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technological scheme: a kind of dynamic and hydrostatic bearing of shallow chamber combination, comprise outer shaft, the inner wall sleeve of described outer shaft is connected to the first rotating shaft, the inwall of described outer shaft is provided with circular groove, the outside of described first rotating shaft is provided with the projection of mating with circular groove, the middle part inner chamber of described first rotating shaft is provided with cavity, the outside of described first rotating shaft is provided with oil hole, described oil hole is positioned at the cavity side of cavity, the inner wall sleeve of described first rotating shaft is connected to the second rotating shaft, the inwall of described first rotating shaft is evenly provided with groove, the outside of described second rotating shaft is evenly provided with the roller with matching grooves, the inner wall sleeve of described second rotating shaft is connected to interior axle, the inwall of described two rotating shafts is provided with restraining groove, the outside of described interior axle is provided with the projection mated with restraining groove.
Preferably, the outer end of described oil hole is plugged with rubber stopper.
Preferably, described groove is curve bath, and described roller and curve bath match.
Compared with prior art, the invention has the beneficial effects as follows: the dynamic and hydrostatic bearing of this shallow chamber combination effectively decreases the friction between bearing, a few thing before also avoid work prepares, relatively common equipment, also avoid while this device improves efficiency and lose time, ensure that the working life of this device is operable more permanent, consume that many factory hours are of a specified duration also can save a lot of money, promote after being worth.
