Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

The first specific embodiment is that as shown in fig. 1 ~ fig. 3, the utility model discloses an engine connecting rod increases journey pinion, including pinion body 1, hard rubber circle 2, auxiliary gear 3, axle sleeve 10, oil plug 11 and a plurality of accuse oil mechanism, a terminal surface of pinion body 1 is equipped with circular recess A, hard rubber circle 2 and auxiliary gear 3 all place in circular recess A, the outer periphery of hard rubber circle 2 and the interior circumference wall fixed connection of circular recess A, the interior circumference of hard rubber circle 2 is equipped with a plurality of internal teeth 2-1 along its circumference, auxiliary gear 3 and hard rubber circle 2 mesh connection, auxiliary gear 3 is fixed the one end of axle sleeve 10 of suit, pinion body 1 rotates the other end of suit at axle sleeve 10 through the bearing, during the use, axle sleeve 10 is fixed the suit on the axostylus axostyle, be equipped with annular oil duct B in gear ring 1-1 of pinion body 1, the oil inlet of annular oil duct B seals the shutoff through oil plug 11, all be equipped with the radial oil outlet C of pinion body 1 in every teeth 1-2 of pinion body, every gear teeth 1-2 of pinion body, every oil outlet C all sets up with oil hole C and corresponding the oil baffle 7, the telescopic link mechanism is equipped with oil outlet C that the fixed baffle 7, the telescopic link mechanism is corresponding to the oil mechanism, the telescopic link C that the fixed baffle is corresponding 4, the oil mechanism, the telescopic link C that the oil mechanism is equipped with the oil hole C that the telescopic rod C that the fixed baffle 7, the telescopic rod C that the telescopic link is corresponding 4, the oil mechanism, the telescopic link is corresponding is equipped with the oil baffle is corresponding to the oil hole C that the oil baffle 7, the telescopic rod.
