Abstract
The utility model relates to a connection structure of bucket and bucket rod of excavator or excavator-loader. The features of the connection structure of bucket and bucket rod is that inner bore positions of both ends of the bucket rod support seat are connected with T lining sleeves; the inner bores of the bucket support seat are respectively connected with T lining sleeve of which end surface is connected with the end surface of the T lining sleeve; the inner bore of the T lining sleeve is sheathed on a pin shaft; therefore, the end surface contact of the support seat is converted into the end surface contact of the T lining sleeve; the material of the T lining sleeve can be manufactured by adopting the material having high strength, good cutting processing, good thermal refining manufacturability, excellent abradability and bending strength and high low-temperature impact property after being treated; therefore, the abradability of the contact end surface is improved, which causes the service time of the end surface of the support seat to be largely improved. The advantages of the connection structure of bucket and bucket rod are that the abradability of the bucket support seat and the bucket rod support seat which have contact end surfaces of the connecting rod support seats is improved, the product life is improved; the adaptability is good and the cost is low.
Description
Technical field
The utility model relates to a kind of The connection structure of scraper pan and bucket arm that is applied to excavator or loader-digger.
Background technology
The scraper bowl of existing excavator or loader-digger is connected the bearing end with dipper, connecting rod, because stressed big, operating mode is abominable, and it is serious therefore should to locate bearing end wear director.Because scraper bowl bearing, dipper bearing and connecting rod support are to need to carry out bore hole and end face milling machine after the welding, generally the material of Cai Yonging all be welding performance and machinability preferably structural carbon steel, low-alloy structural steel or Fine Steel Casting iron as 35, Q345, Q420, Q460 trade mark steel etc.These material hardnesses are all not really high, and abrasion resistance is not fine.Imagination is heat-treated the material of bearing for the abrasion resistance that improves scraper bowl bearing 4, dipper bearing 8 and connecting rod support 10 contact end faces, if before welding, a seat material is heat-treated, then can reduce material welding performance, increase the machine difficulty after welding simultaneously; If the bearing end face is heat-treated,, carry out relatively difficulty of Local treatment, also difficult rectification of the caused distortion of machine post processing simultaneously because welding back structural member is bigger in bonding machine processing back.So it is relatively poor that bearing junction end face is heat-treated manufacturability, in industrial production, seldom use.In addition, adopt special abrasion-resistant stee to improve the abrasion resistance of end face at the bearing place, because special abrasion-resistant stee hardness is very high, the machine additivity is very poor, promotes and gets up to have certain degree of difficulty.For the scraper bowl that improves excavator or loader-digger is connected the abrasion resistance of bearing contact end face with dipper, connecting rod, to be that WC (tungsten carbide) is molten penetrate or the fortified resin pad new technology that adopts at present, and these two kinds of new technology costs are all higher, also generally promote.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, designs a kind of new structure and improves the The connection structure of scraper pan and bucket arm that scraper bowl bearing, dipper bearing have the abrasion resistance of connecting rod support contact end face.
Solution of the present utility model is such: the endoporus place, two ends of dipper bearing is connected with T shape lining, the endoporus of scraper bowl bearing is connected with T shape lining respectively, the end face of T shape lining is connected with the end face of T shape lining, and the end face of T shape lining is connected with the end face of T shape lining; The endoporus of T shape lining is to be socketed on the bearing pin, thereby the end face contact of bearing end face contact becoming T shape lining, the material of T shape lining can adopt the intensity height, machining is good, quenching-and-tempering process is good, the flexural strength that good abrasion resistance is arranged after the processing, the high material of low-temperature impact is made, thereby improved contact end face abrasion resistance is greatly improved in the life-span of bearing end face.
The utility model has the advantages that and can improve the abrasion resistance that scraper bowl bearing, dipper bearing have connecting rod support contact end face, improve life of product, applicability is good, and cost is low.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of T shape bush end face contact position.
Accompanying drawing 3 is stereograms of the present utility model.
The specific embodiment
The utility model includes nut 1, bearing pin 2, bolt 3, scraper bowl bearing 4, T shape lining 5, O-ring seals 6, T shape lining 7, dipper bearing 8, T shape lining 9, connecting rod support 10, lining 11.
The endoporus place, two ends of dipper bearing 8 is connected with T shape lining 7, and the endoporus of scraper bowl bearing 4 is connected with T shape lining (5,9) respectively, and the end face of T shape lining 5 is connected with the end face of T shape lining 7, and the end face of T shape lining 9 is connected with the end face of T shape lining 7; The endoporus of T shape lining (5,7,9) is to be socketed on the bearing pin 2.
Outer edge surface chamfer in T shape lining (5,7,9) makes the chamfering of the end face of T shape lining constitute V-shaped groove after installing, and increases O-ring seals 6 then at the V-shaped groove place, sees accompanying drawing 2, and O-ring seals 6 is just 12 sealings of contact end face slit.So both can prevent effectively that impurity such as silt particle from entering contact surface slit 12, and can prevent effectively that again lubricating grease 12 runs off from the contact surface slit, improved grease at contact surface slit maintenance dose.Therefore, increase O-ring seals 6 at 12 places, contact surface slit and can effectively reduce end wear, can improve the life-span of product bearing end face equally.
Claims (2)
1, a kind of The connection structure of scraper pan and bucket arm, include nut (1), bearing pin (2), bolt (3), scraper bowl bearing (4), dipper bearing (8), connecting rod support (10), the endoporus place, two ends that it is characterized in that dipper bearing (8) is connected with T shape lining (7), the endoporus of scraper bowl bearing (4) is connected with T shape lining (5,9) respectively, the end face of T shape lining (5) is connected with the end face of T shape lining (7), and the end face of T shape lining (9) is connected with the end face of T shape lining (7); The endoporus of T shape lining (5,7,9) is to be socketed on the bearing pin (2).
2, The connection structure of scraper pan and bucket arm according to claim 1 is characterized in that the outer edge surface chamfer in T shape lining (5,7,9).
