Abstract
The invention belongs to the field of mechanical processing, in particular to a hydrodynamic bearing, which comprises a rotating shaft and a shaft sleeve, wherein a wedge oil cavity is arranged between the rotating shaft and the shaft sleeve. The hydrodynamic bearing is characterized in that a central oil hole is arranged on the axis of the rotating shaft, a vertical oil hole which is vertical to the axis is arranged on a position where the rotating shaft corresponds to the wedge oil cavity, the vertical oil hole is communicated with the central oil, a rotating oil pipe is arranged on a position of the central oil hole which is arranged on one end of the rotating shaft, the rotating oil pipe is arranged in a fixed oil pipe, and a sealing ring is arranged on the middle portion. Pressure oil of the invention enters the central oil hole from the fixed oil pipe through the rotating oil pipe, and then enters into the oil cavity through the vertical oil hole. When the rotating shaft rotates, because the action of centrifugal force, the pressure oil is hurled to the oil cavity from the central oil hole through the vertical oil hole, thereby being capable of guaranteeing that the oil cavity steadily supplies oil in a high speed state, the oil mass of the oil cavity of the hydrodynamic bearing is steady, and the vibration of the hydrodynamic bearing is small.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of hydraulic bearing.
Background technique
Hydraulic bearing is to utilize to be compressed in the wedge shape oil pocket of hydraulic oil between running shaft and bearing housing and to produce pressure, the fast more hydraulic fluid pressure of the rotational speed of running shaft is big more, and the oil in the existing oil pocket directly enters between running shaft and bearing housing, this hydraulic bearing when the running shaft high speed rotating because action of centrifugal force, oil easily is thrown out of oil pocket, can cause low on fuel in the oil pocket, thereby make bearing produce vibration.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of interior fuel feeding of employing axle, stable hydraulic bearing of fuel delivery of more reasonable structure is provided.
Technological scheme of the present invention is as follows:
A kind of hydraulic bearing, comprise running shaft, axle sleeve, running shaft and shaft room have the wedge shape oil pocket, it is characterized in that: there is a center oilhole at the axle center at running shaft, vertical oilhole perpendicular to shaft centre line is arranged on the running shaft position corresponding with the wedge shape oil pocket, and vertical oilhole communicates with the center oilhole, and rotation pipeline is equipped with in running shaft one end center oil hole site, rotation pipeline is contained in fixedly in the oil pipe, and seal ring is equipped with in the centre.
Pressure oil of the present invention enters the center oilhole by fixing oil pipe by rotation pipeline, enter oil pocket through vertical oilhole again, when running shaft rotates, because action of centrifugal force, pressure oil can get rid of to oil pocket by vertical oilhole from the center oilhole, can guarantee the stable fuel feeding of fast state lower oil cavitie like this, thereby make the oil pocket oil mass of hydraulic bearing stable, the hydraulic bearing vibration is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of hydraulic bearing, comprise running shaft 1, axle sleeve 2,2 on running shaft 1 and axle sleeve have wedge shape oil pocket 3, it is characterized in that: there is a center oilhole 4 at the axle center at running shaft 1, and the vertical oilhole 5 perpendicular to shaft centre line is arranged on the corresponding position of running shaft 1 and wedge shape oil pocket 3, vertical oilhole 5 communicates with center oilhole 4, rotation pipeline 6 is equipped with in oilhole 4 positions, running shaft one end center, and rotation pipeline 6 is contained in fixedly in the oil pipe 7, and seal ring 8 is equipped with in the centre.
