Description
Technical field
The utility model relates to the syndeton on a kind of walking machine, the anti abrasive scraper bowl that especially a kind of excavator uses and the syndeton of dipper.
Background technology
The end that the scraper bowl of existing excavator is connected with dipper is because stressed big, and operating mode is abominable, and it is serious therefore should to locate the bearing end wear.Because the scraper bowl bearing, dipper bearing end face needs postwelding processing, and generally the material of Cai Yonging all is a welding performance and machinability structural carbon steel preferably, low-alloy structural steel or Fine Steel Casting iron such as Q235, Q345 trade mark steel etc.These material hardnesses are not high; abrasion resistance is bad; some technical scheme has been carried out specially treated for this reason; be designed to T shape such as being installed in the axle sleeve that supports before the dipper, this design has been played protective effect to the end face of dipper, but very big defective is in use arranged; because the hardness of axle sleeve is greater than the hardness of scraper bowl boss; after using a period of time, the boss of scraper bowl can be ground with the groove of an annular, has reduced the application life of scraper bowl on the contrary.Also some technical scheme is when using T oblique crank Z cover, changes the boss material of scraper bowl into steel No. 45, earlier boss itself heat-treated, and carries out hard surfacing after the machine again, adopts weld preheating during welding.The method is seldom used in industrial production because Technology for Heating Processing has certain degree of difficulty, and its welding quality may be subjected to certain influence.There was technical scheme to adopt double T oblique crank Z cover afterwards, material is steel No. 45, but because contact surface can't form stabilizing effective lubricating oil film, two T oblique crank Z cover reality are directly contact, if scraper bowl frequently rotates, on contact surface, can produce a large amount of heats so, after using a period of time, two T oblique crank Z covers can form adhesive wear on the one hand, machined surface to scraper bowl otic placode and bearing pin damages, can quicken the aging of dust ring and O shape circle on the other hand, make impurity such as silt enter the contact surface of axle sleeve and bearing pin, bearing pin and axle sleeve are caused further destruction.The new technology that adopts is the WC(tungsten carbide at present) molten penetrating or the fortified resin pad, but these two kinds of new technology costs are all higher, hinder generally and promote.
