Description
Technical field
The utility model is related to paper machine accessory technical fields, specifically provide a kind of scraper Self-aligning linear bearing.
Background technology
Scraper is common component on paper machine, main function be by applying line pressure in the width direction to roll surface,
Achieve the purpose that clean roll surface.
According to loading form, scraper is divided into gravity type load and pneumatic type load, wherein the work loaded especially with pneumatic type
Effect is higher.But pneumatic type load also will appear some drawbacks, such as：Circular fringes can be formed on roll surface, cause roll surface wearing
It is inconsistent.In order to solve this problem, and oscillating doctor is had developed, i.e., by blade design at can swing back and forth along its axial direction
, annular lines is eliminated by the axial wobble of scraper, keeps roll surface wearing uniform.At this point, being connected in straight on scraper
Spool, which is held, to be just particularly important, this is primarily due to more water of scraper working environment at paper-machine screen splenium, is corrosive
Chemical solution and the environment temperature in drying cylinder portion reach 100 degree, in face of such severe working environment, traditional supra polymer
The embedding graphite linear bearing of polyethylene linear bearing, copper sheathing, ball linear bearing etc. will appear many defects, and then cannot be good
It uses, is in particular in for a long time：
A) ultra high molecular polyethylene linear bearing；Ultra high molecular polyethylene linear bearing has preferable corrosion resistance, but
Since ultra high molecular polyethylene material has certain water imbibition dilatancy, once for a long time, ultra high molecular polyethylene linear bearing meeting
Blade shaft is held tightly, in this case, the load of wig-wag motor can increase, and motor can be burnt out when serious；In addition, due to superelevation point
Sub- polythene material is not wear-resisting, and when on broadsheet machine, since scraper is heavier, ultra high molecular polyethylene linear bearing can be very
It is worn soon；Therefore, the availability of ultra high molecular polyethylene linear bearing is not strong.
B) the embedding graphite linear bearing of copper sheathing；The coefficient of friction of this linear bearing is larger, the meeting in heavier scraper device
It causes to swing irregularity, cutter hub is shaken.And this bearing can slowly get rusty when meeting acid-base property liquid, working life compared with
It is short.
C) ball linear bearing；This bearing makes of high carbon bearing steel, it is easy to get rusty, so must be installed into sealing
In the good bearing block of property.But when being swung because of the scraper at paper-machine screen splenium, blade shaft is stretched into and is pulled out in bearing block, is held
Negative pressure is easily formed, causes water to enter in bearing block, so that linear bearing corrosion, influences working life.In addition, papermaking
Although Ji Hong Division of Personnel is without water, since ball and sliding sleeve are point contacts, contact stress is larger, and due to existing structure original
Cause, it is difficult to designing increase is used for grease-added channel, so, the working life of ball linear bearing is also shorter.
In view of this, special propose the utility model.
