Preferably, described bearing comprises bearing body and bearing cover, and described bearing body and bearing cover complement each other to form dead eye.
Preferably, between described bearing body and bearing cover, be also provided with adjusting pad.
Preferably, on described bearing body, the other end with respect to described bearing cover one end is connected with push arm.
Preferably, the body of described gudgeon protective cover and described bearing are bolted to connection.
Preferably, on the bearing body of described bearing and bearing cover, be equipped with threaded block, described body is provided with the screwed hole matching with described threaded block.
Preferably, the quantity of the threaded block on described bearing body is 1, and the quantity of the threaded block on described bearing cover is 2.
Preferably, on the screwed hole of described body, be also provided with packing ring.
Preferably, described gudgeon protective cover is shaped as disc.
On the other hand, provide a kind of bulldozer, comprise the perching knife being connected with push arm, bearing and gudgeon, be also provided with gudgeon protective cover described above.
With respect to prior art, the advantage of the technical solution of the utility model has:
1, gudgeon protective cover profile of the present utility model is simple, is easy to casting;
2) fixed form of the utility model gudgeon protective cover is easy to dismounting, does not affect bearing assemble, and is convenient to while being damaged change;
3) gudgeon protective cover of the present utility model can also play dustproof effect, slows down bearing abrasive wear.
