Abstract
The utility model discloses a T-shaped bush on a bucket rod, which comprises a bucket body, an O-shaped seal ring, a T-shaped bush, the bucket rod, a hinge pin, a dust ring, a bucket lug boss, a screw bolt and a screw nut. The bush at the front end of the bucket rod is made to be T-shaped, the T-shaped bush is made from 45# steel, and the workblank of the T-shaped bush is firstly hardened and tempered: HB 229-277, the end face of a part Q and a surface P are quenched: HRC 52-60, the rigidity of the two parts of the T-shaped bush is improved, so that the abrasive resistance of the end face of the T-shaped bush and the abrasive resistance of the inner surface of the T-shaped bush can be greatly improved. The abrasive resistance of the two end faces at the front end head of the bucket rod and the abrasive resistance of the end face of the bucket lug boss can be improved, the service life of the bucket rod is prolonged, the structure is simple, the cost is low, the effect is obvious, the change is convenient, and the applicability is good.
Description
Technical field
The utility model relates to a kind of dipper of excavator and the T shape bush structure on the scraper bowl link bucket bar.
Background technology
The dipper of existing excavator is connected end face with scraper bowl, when digging operation, because stressed big, operating mode is abominable, rotates frequently its as easy as rolling off a log wearing and tearing, further cause excavator boom and scraper bowl junction fit clearance to strengthen, thereby produce noise pollution, the application life of reducing dipper.And steel cylinder that the general abrasion resistance of dipper front end is relatively poor, hardness is not high or steel-casting, in order to improve dipper is connected end face with scraper bowl abrasion resistance, present main way is:
1. use oxy-acetylene flame surfacing one deck nickel-based self-fluxing alloy powder as wearing layer in dipper front end both ends of the surface (as figure one A, B face).But this processing method manufacturability is poor, and spray-welding coating is thin and inhomogeneous, the cost height;
2. the whole steel cylinder of dipper front end or steel-casting are carried out modifier treatment.The hardness that this processing method obtains is not high, can not satisfy wear-resisting requirement, and whole steel cylinder or steel-casting carry out modifier treatment, and volume is bigger, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of dipper to be connected with the scraper bowl body by T shape lining, bearing pin, T shape lining is installed on the dipper, dipper is connected with the scraper bowl raised head face by T shape bush end face, connect together by bearing pin and scraper bowl body, bearing pin is together locked by screw bolt and nut and scraper bowl body.The abrasion resistance of raising dipper and scraper bowl raised head face, simple in structure, easy to manufacture, the T shape lining on the dipper easy to install.
Technical solution of the present utility model is: the T shape lining of excavator boom and scraper bowl hinged place, comprise scraper bowl body, O-ring seals, T shape lining, dipper, bearing pin, dust ring, scraper bowl boss, bolt, nut, it is characterized in that dipper passes through T shape lining, bearing pin is connected with the scraper bowl body, T shape lining is installed in dipper, T shape lining is installed bearing pin by the hole, dipper is connected with the scraper bowl raised head face by T shape bush end face, and by bearing pin and the socket of scraper bowl body, bearing pin is connected with the scraper bowl body by screw bolt and nut.
T shape lining has the hole and the stepped hole that is used to adorn dust ring with the bearing pin socket.
0 shape sealing ring is installed between T shape lining and the scraper bowl boss.
Advantage of the present utility model: dipper is by T shape lining, bearing pin is connected with the scraper bowl body, dipper front end lining is made " T " font, T shape lagging material is selected the 45# steel for use, earlier T shape lining blank is carried out modifier treatment: HB229～277, the Q end surface, the P surface is carried out hard surfacing and is handled: HRC52～60, improve the hardness at these two positions of T shape lining, so just can improve the abrasion resistance of T shape bush end face and inner surface greatly.Can improve the abrasion resistance of dipper front end both ends of the surface and scraper bowl raised head face, prolong the application life of dipper, and simple in structure, with low cost, effect obviously, change convenient, applicability is good.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is dipper and the bush structure schematic diagram that generally adopts now.
Fig. 2 installs sectional arrangement drawing for the utility model overall structure.
Fig. 3 looks sectional view for the utility model T shape lining master.
Fig. 4 is the utility model T shape lining vertical view.
Among Fig. 1～Fig. 4, scraper bowl body (1), O-ring seals (2), T shape lining (3), dipper (4), bearing pin (5), dust ring (6), scraper bowl boss (7), bolt (8), nut (9), stepped hole (10).
The specific embodiment
Most preferred embodiment of the present utility model is such: with reference to Fig. 1～Fig. 4, dipper 4 is by T shape lining 3, and bearing pin 5 is connected with scraper bowl body 1.The outer likeness in form of T shape lining 3 " T " fonts, T word end face have stepped hole 10T shape lining 3 to have hole with bearing pin 5 sockets.T shape lining 3 is selected the 45# steel for use, earlier T shape lining 3 blanks is carried out modifier treatment HB229～277, and Q holds end face, and Quenching Treatment is carried out on the P surface, and HRC52～60 are improved 3 two positions of T shape lining and more do not become.
Referring to Fig. 2, T shape lining 3 is installed on dipper 4; Dipper 4 is connected with scraper bowl boss 7 end faces by T shape lining 3 end faces, and connects together by bearing pin 5 and scraper bowl body 1, and bearing pin 5 is in the same place with the scraper bowl body is locked by bolt 8 and nut 9.Simple in structure, easily manufactured.
Referring to Fig. 3 and Fig. 4, T shape lining 3 has the hole and the stepped hole 10 that is used to adorn dust ring 6 with bearing pin 5 sockets.
Referring to Fig. 2, Fig. 3 and Fig. 4, T shape lining 3 end faces and scraper bowl boss 7 end faces constitute V-shaped groove, can install to be used for preventing dust and holding oily O-ring seals 2 on V-shaped groove.
The utility model only need change the material and the contour structures of lining, realizes prolonging the dipper purpose in application life easily.
The utility model does not limit use on the dipper of hydraulic crawler excavator, may also extend into the various frame for movements that similar this two parts end faces rub mutually.
