Abstract
The invention discloses a bushing for a bucket rod of an excavator. The bushing comprises a bucket body, an O-ring, a T-shaped bushing body, the bucket rod, a hinge pin, a dust ring, a bucket boss, a bolt and a nut. The bushing body at the front end of the bucket rod is T-shaped, the T-shaped bushing body is made of 45# steel, a blank of the T-shaped bushing body is subjected to thermal refining firstly in the hardness value range of HB229-277, the Q end face and the P surface are subjected to surface hardening in the harness value range of HRC52-60, and the hardness of the two portions of the T-shaped bushing body is improved, so that abrasion resistance of the end face and the inner surface of the T-shaped bushing body can be improved greatly, abrasion resistance of two end faces of the front end of the bucket rod and the end face of the bucket boss can be improved, and the service life of the bucket rod can be prolonged. The bushing is simple in structure, low in cost, obvious in effect, convenient to replace and good in applicability.
Description
Technical field
The present invention relates to lining on a kind of dipper of excavator and a kind of excavator boom on the scraper bowl connecting end surface dipper.
Background technology
Dipper and the scraper bowl connecting end surface of existing excavator are when digging operation, because stressed large, 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 the 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 the abrasion resistance of dipper and scraper bowl connecting end surface, present Main 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 (such as Figure 1A, B face).But this processing method manufacturability is poor, and spray-welding coating is thinner and inhomogeneous, and cost is high;
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 larger, and cost is higher.
Summary of the invention
The objective of the invention is to be 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 invention is: lining on a kind of excavator boom, 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 with the hole of bearing pin socket with for the stepped hole that fills dust ring.
Between T shape lining and the scraper bowl boss O-ring seals is installed.
Advantage of the present invention is: 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, first 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 processed: HRC52～60, improve the hardness at these two positions of T shape lining, so just can greatly improve the abrasion resistance of T shape bush end face and inner surface.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, successful, replacing is convenient, applicability is good.
Description of drawings
Formation of the present invention is:
Fig. 1 is dipper and the bush structure schematic diagram that generally adopts now.
Fig. 2 is that overall structure of the present invention is installed sectional arrangement drawing.
Fig. 3 is that T shape lining master of the present invention looks sectional view.
Fig. 4 is T shape lining top view of the present invention.
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
The invention will be further described below in conjunction with accompanying drawing, and dipper 4 is by T shape lining 3, and bearing pin 5 is connected with scraper bowl body 1.T shape lining 3 outer likeness in form " T " fonts, T word end face have stepped hole 6T shape lining 3 to have the hole that is socketed with bearing pin 5.T shape lining 3 is selected the 45# steel, first 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, at dipper 4 T shape lining 3 is installed; 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 7 and nut 9.Simple in structure, easily manufactured.
Referring to Fig. 3 and Fig. 4, T shape lining 3 has with the hole of bearing pin 5 sockets with for the stepped hole 10 that fills dust ring 6.
Referring to Fig. 2, Fig. 3 and Fig. 4, T shape lining 3 end faces and scraper bowl boss 7 end faces consist of V-shaped groove, can install on V-shaped groove for preventing dust and holding oily O-ring seals 2.
The present invention only need change material and the contour structures of lining, realizes easily prolonging the dipper purpose in application life.
The present invention does not limit and uses 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.
