Abstract
The utility model provides a kind of active and static pressure mixed type sliding bearing, comprises bearing shell, is provided with axle sleeve in bearing shell, and bearing shell is provided with multiple bearing shell spiral chute, and axle sleeve is provided with multiple axle sleeve spiral chute, and bearing shell spiral chute is contrary with axle sleeve spiral chute direction; Preferably, bearing shell spiral chute and axle sleeve spiral fluted quantity prime number each other.The utility model bearing shell and axle sleeve all have spiral chute, increase the liquid storage amount between bearing shell and axle sleeve, be not easy the phenomenon occurring liquid measure deficiency, bearing shell is contrary with axle sleeve spiral chute direction, is very easy to the gap brought into by liquid between the two, due to the effect of axle sleeve spiral fluted, form a micro-screw pump, produce static pressure, form the liquid film of dynamic pressure static pressure mixing, add liquid film strength, liquid film is not easy to be destroyed.Spiral fluted quantity is arranged to prime number each other, can not form the harmonic wave of resonance, and bearing can stably be run.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of active and static pressure mixed type sliding bearing.
Background technique
Old-fashioned canned motorpump, magnetic force Sliding bearing for pump adopt the structure that straight trough left by bearing shell, axle sleeve is not slotted, lubricating fluid between bearing shell and axle sleeve is fewer, what formed is dynamic pressure liquid film, once there is fluctuation in fluid pressure, be easy to occur that liquid measure is not enough, dynamic pressure film is incomplete, produces the dry grinding phenomenon of local, causes bearing damage.
Summary of the invention
The utility model provides a kind of active and static pressure mixed type sliding bearing, and the shortcoming because of insufficient lubrication damage bearing easily appears in the sliding bearing solved in background technique.
The technical solution of the utility model is achieved in that a kind of active and static pressure mixed type sliding bearing, comprise bearing shell, be provided with axle sleeve in bearing shell, bearing shell is provided with multiple bearing shell spiral chute, axle sleeve is provided with multiple axle sleeve spiral chute, and bearing shell spiral chute is contrary with axle sleeve spiral chute direction;
Preferably, bearing shell spiral chute and axle sleeve spiral fluted quantity prime number each other.
The beneficial effects of the utility model are: the utility model bearing shell and axle sleeve all have spiral chute, increase the liquid storage amount between bearing shell and axle sleeve, be not easy the phenomenon occurring liquid measure deficiency, bearing shell is contrary with axle sleeve spiral chute direction, is very easy to the gap brought into by liquid between the two, due to the effect of axle sleeve spiral fluted, form a micro-screw pump, produce static pressure, form the liquid film of dynamic pressure static pressure mixing, add liquid film strength, liquid film is not easy to be destroyed.Spiral fluted quantity is arranged to prime number each other, can not form the harmonic wave of resonance, and bearing can stably be run.The lead of screw of bearing shell and axle sleeve is also slightly different, causes the flow velocity in the two groove slightly different, is conducive to the stable of the liquid film formed, ensures bearing reliability of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Part illustrates: 1, bearing shell, 2, axle sleeve, 3, bearing shell spiral chute, 4, axle sleeve spiral chute.
Embodiment
In order to Comprehension and Implementation better, below in conjunction with accompanying drawing, the utility model is further described: a kind of active and static pressure mixed type sliding bearing, comprise bearing shell 1, axle sleeve 2 is provided with in bearing shell 1, bearing shell 1 is provided with 6 spiral chutes, axle sleeve 2 is provided with 5 spiral chutes, and bearing shell spiral chute 3 is contrary with axle sleeve spiral chute 4 direction.
Bearing shell and axle sleeve all have spiral chute, increase the liquid storage amount between bearing shell and axle sleeve, are not easy the phenomenon occurring liquid measure deficiency.Bearing shell is contrary with axle sleeve spiral chute direction, is very easy to the gap brought into by liquid between the two.Due to the effect of axle sleeve spiral fluted, form a micro-screw pump, produce static pressure, form the liquid film of dynamic pressure static pressure mixing, add liquid film strength, liquid film is not easy to be destroyed.Spiral fluted quantity is arranged to prime number each other, can not form the harmonic wave of resonance, and bearing can stably be run.The lead of screw of bearing shell and axle sleeve is also slightly different, causes the flow velocity in the two groove slightly different, is conducive to the stable of the liquid film formed, ensures bearing reliability of operation.
