Abstract
The invention discloses a wear resistant ceramic cam ring, raw materials of which comprises alumina ceramic with the content of alumina being 75-100% and zirconia ceramic with the content of zirconia being 75-100%. The ceramic cam ring comprises a cam ring body; three bumps with equal interval are arranged on one side of the cam ring body; and three grooves, corresponding to the three bumps, are formed in the other side of the cam ring body, and communicate with one another through an annular groove. The service life of the cam ring is prolonged due to high wear resistance of ceramic; the cost is reduced; and the labor efficiency is improved.
Description
Technical field
The present invention relates to high-performance ceramic preparing technical field, particularly relate to a kind of wear-resistant ceramic cam ring and preparation method thereof.
Background technology
Electric screw driver turns the driver bit driven usually by drive-motor, and to be set between this motor and driver bit, to transmit the transmission of power row of rotary driving force of motor.In transmission of power row, be provided with when applying the load torque to a certain degree to driver bit, by the transmission of power partition apparatus in transmission of power row, this transmission of power partition apparatus has discoid cam ring, at the spheroid that axis direction and this cam ring end face of driver bit abut against, extend to described axis direction and apply the compression spring abutting pressure between this spheroid with discoid cam ring, and regulating the adjustment member of the compression degree of this compression spring on described axis direction.Usually cam ring used is easy to wear, regularly needs to change, and increases cost.
Oxide ceramic part is widely used in fields such as machinery, chemical industry and automobiles, such as zirconium white or alumina-ceramic gear and ceramic screw etc.The method of this multiple tooth oxide ceramic part of current manufacture comprises the methods such as isostatic pressed, dry-pressing, slip casting and injection moulding.Although ceramic dry-pressed efficiency is higher, there is the uneven phenomenon of density variation, microstructure in moulding product, simultaneously not easy-formation complicated shape and special-shaped product; Cold isostatic compaction can obtain the molding blank of high-density and high uniformity, but is difficult to the ceramic part of forming shape complexity, and shaping efficiency is low and manual operations is many.Though the shaping plastic special-shaped product of ceramic grout, reach near net-shape, molding blank easily produces density unevenness and component segregation, degradation problem under the low and product reliability of compact dimensions precision, and is shaped to manual operations and body drying efficiency is low.Hot die-casting molding maximum problem production cycle is long, is inefficiency, gets rid of the organic binder bonds such as paraffin and needs dozens or even hundreds of hour, and easily produce the defect such as pore and cracking in de-waxing process.
Summary of the invention
The object of the present invention is to provide a kind of wear-resistant ceramic cam ring and preparation method thereof.
To achieve these goals, the present invention adopts following technical scheme:
A kind of wear-resistant ceramic cam ring, its raw material is alumina content is the alumina-ceramic of 75% ~ 100% or the zirconia ceramics of zirconia content 75% ~ 100%.
Described ceramic cam ring includes cam ring body, described cam ring body is equidistantly provided with three salient points, and described three salient points corresponding cam ring body another side is provided with three grooves, and three described grooves are connected by an annular groove.
Described wear-resistant ceramic cam ring preparation process is as follows:
1) feeding: ceramic powder and polymethylmethacrylate (PMMA)+polyethylene oxide (PEO) composite adhesive system are mixed to form Feedstock of Powder Injection Molding in 88-92wt%: 8-12wt% ratio;
2) injection molding: injection molding mixture installs screw rod grinding tool on injection moulding machine and injection molding obtains base substrate, injection temperature is between 175-195 DEG C, and after injecting mould, in 2 minutes, the demoulding obtains molding blank;
3) come unstuck: base substrate injection molding obtained puts into degumming machine, dissolve and remove part organic binder bond, temperature controls at 30-50 DEG C, and degreasing time is at 6-8 hour, and the base substrate after coming unstuck is fully dry in an oven;
4) sinter: the base substrate after coming unstuck sinters in sintering oven, sintering temperature is between 1350-1550 DEG C, and insulation 1-4 hour, furnace cooling, obtains ceramic component.
Beneficial effect of the present invention:
The present invention utilizes the high-wearing feature of pottery to improve work-ing life; Reduce costs, efficiency is provided.
