Abstract
The utility model discloses a kind of long lifetime central shaft, comprise generic central outer shaft sleeve, ceramic inner sleeve; Pottery inner sleeve is embedded in generic central axle two ends, in pottery, cover requires machining center hole according to the tapering of thimble, adopts screw thread or hot pressing to be connected between generic central outer shaft sleeve with ceramic inner sleeve.This structure well solves because of central shaft center hole wearing and tearing and cause equipment precision to reduce and product to be processed precision does not reach the problem of requirement in operation, solves the problem that central shaft is not wear-resisting, the life-span is short simultaneously.It is widely used in mechanical processing industry, greatly the working life of extension device, improves equipment precision, reduces enterprise's cost of production.
Description
One, technical field
The utility model relates to a kind of long lifetime central shaft.
Two, background technique
Central shaft is indispensable core fixture in mechanical processing industry, or even the important transmission component that some equipment inherently has, if the precision of central shaft goes wrong, so thus equipment or thus central shaft be that the precision of any product that reference point processes certainly also there will be problem, because centre bearing is greatly stressed, precision prescribed is high, be easy in operation be worn, working life is very short, have a strong impact on the precision of equipment or product to be processed, and long lifetime central shaft satisfactory solve short problem in generic central axle not wear-resistant working life.
Three, summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, solid and reliable, wear-resistant, long lifetime central shaft.
The purpose of this utility model is achieved in that a kind of long lifetime central shaft, it is characterized in that: generic central outer shaft sleeve (1), ceramic inner sleeve (2); Pottery inner sleeve (2) is embedded in generic central axle (1) two ends, ceramic inner sleeve (2) requires machining center hole (3) according to the tapering of thimble, between generic central outer shaft sleeve (1) with ceramic inner sleeve (2), adopts screw thread or hot pressing to be connected.
A kind of long lifetime central shaft of the present utility model, comprises generic central outer shaft sleeve, ceramic inner sleeve; Pottery inner sleeve is embedded in generic central axle two ends, in pottery, cover requires machining center hole according to the tapering of thimble, adopts screw thread or hot pressing to be connected between generic central outer shaft sleeve with ceramic inner sleeve.This structure well solves because of central shaft center hole wearing and tearing and cause equipment precision to reduce and product to be processed precision does not reach the problem of requirement in operation, solves the problem that central shaft is not wear-resisting, the life-span is short simultaneously.It is widely used in mechanical processing industry, greatly the working life of extension device, improves equipment precision, reduces enterprise's cost of production.
Four, accompanying drawing explanation
Fig. 1 is a kind of long lifetime central shaft elevational schematic of the utility model.
Five, embodiment
Below in conjunction with accompanying drawing, detailed description is done to the utility model.
Long lifetime central shaft as a kind of in Fig. 1, is characterized in that: generic central outer shaft sleeve (1), ceramic inner sleeve (2); Pottery inner sleeve (2) is embedded in generic central axle (1) two ends, ceramic inner sleeve (2) requires machining center hole (3) according to the tapering of thimble, between generic central outer shaft sleeve (1) with ceramic inner sleeve (2), adopts screw thread or hot pressing to be connected.
