Abstract
The utility model relates to a new improved cooling structure applied on an oil pump bearing, comprising a pump axle, a bearing, a bearing suspension frame and a bearing suspension frame cooling cavity, characterized in that: an axle sleeve is arranged in the inner circle of bearing connected with the pump axle and made of normal-pressure sintered silicon carbide and the axle sleeve is composed of two semi-sleeves. The advantages of the utility model are that: the direction contact surface of the bearing inner circle and the pump has very good heat block function and the installation is simple.
Description
Technical field
The utility model relates to a kind of cooling structure of oil pump bearing, particularly a kind of improved new structure of cooling that is applied to the oil pump bearing.
Background technique
The occasion that oil pump uses generally all is environment and medium situation more complicated harshness, modal is exactly the occasion of High Temperature High Pressure, the high-temperature field is fashionable facing, part of its auxiliary cooling particular importance that just seems, because the thermal distortion that high temperature causes and the influence of bearing is enough to make unit generation major accident, the existing bearing cooling structure all is that the suspension body to bearing cools off, just a cooling chamber is being set on the bearing suspension near the pump head end, it can stop the transmission of heat to bearing outer ring, simultaneously also can a spot of cutting oil, but the inner ring cooling effect of bearing is not obvious, but inner ring rotates with axle again, so to cool off it cumbersome, existing structure mainly be oil by the grease chamber to its not only lubricated but also cooling, but the effect of cooling is undesirable.
Summary of the invention
The purpose of this utility model is the effective cooling bearing outer ring and can not fine cooling bearing inner ring existing to the unfavorable problem of oil pump bearing cooling effect of cooling structure that solves oil pump.A kind of improved new structure of cooling that is applied to the oil pump bearing is provided.A kind of improved new structure of cooling that is applied to the oil pump bearing of the utility model design, comprise pump shaft, bearing, bearing suspension, bearing suspension cooling chamber, it is characterized in that: there is an axle sleeve at the inner ring place at the pump shaft connection bearing, and axle sleeve is that normal pressure-sintered silicon carbide is made.It is characterized in that: axle sleeve is made up of the cover of two branches half.The utility model has the advantages that the direct contact surface that can reduce bearing inner race and axle greatly is long-pending, can play good thermal resistance effect, and install simple.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise pump shaft 1, bearing 2, bearing suspension 3, bearing suspension cooling chamber 4 among the figure, it is characterized in that: there is an axle sleeve 5 at the inner ring place at pump shaft 1 connection bearing 2, and axle sleeve 5 is made for normal pressure-sintered silicon carbide.It is characterized in that: axle sleeve 5 is made up of the cover of two branches half.
Here, consider that at first the heat affecting that bearing is subjected to is exactly the conduction of heat, the outer ring is transmitted with bearing suspension body, intercepted a large amount of transmission of heat by cooling chamber, the heat of inner ring mainly comes from the conduction of pump shaft to heat so, if want to reduce or the conduction of trap heat, pump shaft is cooled off less feasible, so just can only try every possible means to allow bearing directly not contact as far as possible with pump shaft, the utility model adopts and adopt the mode that adds cover between pump shaft and bearing inner race, to adding an axle sleeve on the pump shaft, bearing inner race is installed on the axle sleeve again, this axle sleeve adopts existing certain rigidity that the material of good heat rejection effect can also be arranged, the direct contact surface that so just can reduce bearing inner race and axle greatly is long-pending, more common material has normal pressure-sintered silicon carbide now, because it has good temperature tolerance and rigidity, moldability is also better, can play good thermal resistance effect, also can bear the power of rotation, when making, make the cover of two branches half, two halves directly snap on the pump shaft during installation, utilize the inner ring of bearing that they are fixed on pump shaft then, and fabrication and installation are all fairly simple.
Claims (2)
1. the improved new structure of cooling that is applied to the oil pump bearing comprises pump shaft, bearing, bearing suspension, bearing suspension cooling chamber, and it is characterized in that: there is an axle sleeve at the inner ring place at the pump shaft connection bearing, and axle sleeve is that normal pressure-sintered silicon carbide is made.
2. by the described a kind of improved new structure of cooling that is applied to the oil pump bearing of claim 1, it is characterized in that: axle sleeve is made up of the cover of two branches half.
