Description
Technical field
It the utility model is related to a kind of Ceramic fitting technical equipment field, more particularly to a kind of alumina ceramic axle sleeve.
Background technology
The ceramic shaft tool of high rate wastewater pump is made up of Ceramic shaft sleeve and baffle plate before this.Water pump produces when running at high speed
Larger noise and vibration, due to being all plane contact between Ceramic shaft sleeve and baffle plate, it can not accomplish to reduce noise and reduce to shake
It is dynamic, therefore influence the stability and service life of equipment.
In high speed shaft member because the abrasion for running at high speed, rubbing and causing part between axis body and axle sleeve, when axle and
The gap wear in hole to a certain extent when, it is necessary to renewal part, thus from wearability ceramic material as axle sleeve or
Bushing, it is possible to reduce the abrasion of axle and seat, save the cost for changing axis body；Due to move the abrasion that brings be it is inevitable,
How to reduce abrasion, extend Main Shaft Service Life, and axially position is played by axle sleeve and acted on, reduce spindle vibration, reduce high
The dry sound of speed operation is the problem of industry.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of alumina ceramic axle sleeve, in the prior art
Deficiency, using alumina ceramic material, set inner groove to be used to store lubricating oil on the inside of sleeve body, and by spacing flat
Platform and Sealing shield ring limit shaft sleeve are on main shaft, and Ceramic shaft sleeve is wear-resisting, corrosion-resistant, high temperature resistant degree, reduce abrasion, and extension uses the longevity
Life.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：A kind of alumina ceramic axle sleeve, including axle sleeve sheet
Body, inner groove, Sealing shield ring, spacing chuck, half groove of orientation, axis hole, it is characterised in that：
The sleeve body is the rotating cylinder that alumina ceramic material forms by a firing, and axle is provided with the sleeve body
Hole, staged limiting platform is provided with axis hole one end inside circumference face of the sleeve body, is set below the limiting platform
It is equipped with Sealing shield ring；Inner groove is provided with the axis hole other end inside circumference face of the sleeve body, the inner groove is used for
Store lubricating oil；The outside of the sleeve body has axially been uniformly arranged half groove of multiple orientations.
Half slot cross-section of the orientation is shaped as semicircle hole slot, and the length of half groove of the orientation is less than or equal to the axle sleeve
The half of body height.
The internal diameter of the Sealing shield ring is less than the internal diameter of the axis hole.
Half groove of the orientation is at least provided with two.
Pass through above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model are：Using alumina ceramic material,
Set on the inside of sleeve body inner groove to be used to store lubricating oil, and spacing by limiting platform and Sealing shield ring so that main shaft with
Ceramic shaft sleeve coordinates, and Ceramic shaft sleeve has high mechanical strength, wear-resisting, corrosion-resistant and high temperature resistant degree premium properties, raw material valency
Lattice are low；And by adding lubricating oil between axle and sleeve lining, to reduce frictional force, so as to reduce abrasion, improving extension makes
Use the life-span.
