Abstract
The invention discloses a connecting structure of a bucket pin roll. The connecting structure comprise the pin roll, wherein lug plates are arranged at the outer side of the circumference of the pin roll in a sleeving manner and are close to the two end parts of the pin roll; end covers are arranged at two ends of the pin roll; an O-shaped seal ring is arranged between each end cover and the corresponding lug plate; lug plate bushes are arranged at the outer walls of the circumference at two ends of the pin roll in a sleeving manner; each lug plate is arranged on the corresponding lug plate bush in a sleeving manner; a first oil cup is radially formed in each end cover and is communicated to a space formed between the end cover and the end surface of the pin roll; a front support is arranged at the inner side of each lug plate and at the outer side of the pin roll in a sleeving manner; front support bushes are arranged at the outer side of the pin roll and are close to the lug plate bushes; the inner sides of two ends of the front support are arranged on the front support bushes in a sleeving manner; a second oil cup is radially formed in the front support and is communicated to a space formed between the front support and the pin roll; an oil seal is arranged between each lug plate bush and the corresponding front support bush. According to the connecting structure of the bucket pin roll, the abrasion of the pin roll can be alleviated or avoided, and therefore the service life of the pin roll is prolonged.
Description
Technical field
The present invention relates to bearing pin, specifically a kind of scraper bowl pin shaft connection structure.
Background technique
Common digging machine scraper bowl bearing pin adopts one end fixed, main bolt and the pressing plate of adopting fixed, and the bearing pin of this means of fixation work is motionless, easy to wear in working procedure, larger on impact in bearing pin working life, therefore research and develop, a kind ofly can reduce or avoid the pin shaft connection structure of wearing and tearing particularly important.
Summary of the invention
The object of the present invention is to provide a kind of scraper bowl pin shaft connection structure, can reduce or avoid the wearing and tearing of bearing pin, and then strengthen the working life of bearing pin, reduce costs.
In order to reach above-mentioned purpose, the present invention has adopted following technological scheme, a kind of scraper bowl pin shaft connection structure, comprise bearing pin, described bearing pin has otic placode near the periphery cover at self two end part, and described bearing pin two end part all arrange end cap, and O RunddichtringO is set between described end cap and otic placode.
Described bearing pin two ends outer circumferential walls cover has otic placode lining, and described otic placode is enclosed within on otic placode lining, offers the first lubricating cup radially on described end cap, and the first lubricating cup is communicated to the space forming between end cap and pin roll end face.
Described otic placode inner side and bearing pin outside cover have front support.
Described bearing pin outside and be provided with front support lining near otic placode lining position, inner side, described front support two ends is enclosed within on front support lining.
Described front support is offered the second lubricating cup radially, and the second lubricating cup is communicated to the space forming between front support and bearing pin, between described otic placode lining and front support lining, oil sealing is set.
Compared to prior art, the present invention has following beneficial effect:
When Joystick, by stretching of oil cylinder, traction scraper bowl rotates around bearing pin together with otic placode, by the first lubricating cup and the second lubricating cup, inject lubricant grease lubricated, under good lubrication state, bearing pin is stressed in two otic placode linings and front support lining, friction is even, free to rotate, bearing pin uneven wear situation is stopped, and bearing pin wearing and tearing alleviate greatly.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of scraper bowl pin shaft connection structure of the present invention.
In figure: 1, end cap; 2, otic placode; 3, otic placode lining; 4, front support lining; 5, front support; 6, the first lubricating cup; 7, bearing pin; 8, oil sealing; 9, O RunddichtringO, 10, the second lubricating cup.
Embodiment
Relevant detailed description of the present invention and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the present invention to be limited.
With reference to accompanying drawing 1, a kind of scraper bowl pin shaft connection structure, is mainly comprised of end cap 1, otic placode 2, otic placode lining 3, front support lining 4, front support 5, the first lubricating cup 6, bearing pin 7, oil sealing 8, O RunddichtringO 9, the second lubricating cup 10.2 front support linings 4 are assemblied in respectively front support 5 two ends, and the first lubricating cup 6 is installed in front support 5, form supporting sleeve assembly; 2 otic placode linings 3 are assemblied in respectively on 2 otic placodes 2, form otic placode assembly; The second lubricating cup 10, O RunddichtringO 9 are installed on end cap 1, form end-cap assembly; Bearing pin 7 symmetries are assemblied in supporting sleeve assembly two front support linings 4; Otic placode assembly is assemblied in the two ends of bearing pin 7 by otic placode lining 3; End-cap assembly is installed on the otic placode 2 of otic placode assembly.
Bearing pin of the present invention 7, can synchronously rotate by 2 end caps 1 and 2 O RunddichtringO 9 shutoff in the cavity being comprised of otic placode lining 3, front support lining 4, front support 5, has avoided the relative friction of bearing pin 7 with otic placode lining 3 and front support lining 4.
The foregoing is only preferred embodiment of the present invention, non-in order to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
Claims (5)
