Description
Technical Field
The utility model mainly relates to a battery production field especially relates to a turbo charger footstep bearing.
Background
The thrust bearing is one of the key components of a turbocharger. With the increasing strengthening degree of modern engines, especially with the stricter requirements of various countries on environmental regulations, the working speed and pressure ratio of the turbocharger is continuously increased, the working condition is more severe, and the lubricating and cooling conditions are worse. The supply condition of lubricating oil has great influence on the mechanical efficiency and reliability of the thrust bearing, and the main method for increasing the unbalanced bearing capacity of the axial force of the turbocharger at present is to increase an oil inlet hole on the end face of the thrust bearing, so that the flow of the lubricating oil is added to improve the lubricating effect, but the lubricating effect is poor and the use cost of the lubricating oil is increased.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect of prior art, the utility model provides a turbo charger footstep bearing, including footstep bearing body 1, footstep bearing body 1 center is equipped with mounting groove 2, the outer circumferencial ring of 2 mounting grooves is equipped with oil wedge face 3, the outer circumferencial ring of 3 outer circumcircles of oil wedge faces is equipped with lubricating layer 4, and 4 top intercommunications of lubricating layer have oil groove 5, and 5 top intercommunications of oil groove have oil filler point 6.
Preferably, the oil wedge surfaces 3 are three and are all fan-shaped.
Preferably, fan-shaped gaps are arranged among the three oil wedge surfaces 3.
Preferably, the bottom of the thrust bearing body 1 is provided with a notch.
Preferably, the main filler of the lubricating layer 4 is sponge.
Preferably, the oil groove 5 is in a step shape.
Preferably, the bottom of the oil filling hole 6 is sealed.
The utility model has the advantages that: and a lubricating layer is added in the bearing, so that the lubricating effect is improved, and the oil consumption is saved.
