Description
Technical field
The utility model 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 employing bolt and pressing plate are fixed, and the bearing pin of this means of fixation work is motionless, easy to wear in working procedure, comparatively large on bearing pin impact in working life, therefore it is particularly important to research and develop a kind of pin shaft connection structure that can reduce or avoid to wear and tear.
Summary of the invention
The purpose of this utility model 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 strengthens the working life of bearing pin, reduces costs.
The purpose of this utility model realizes by following technological scheme:
This scraper bowl pin shaft connection structure comprises bearing pin, and the periphery cover of described bearing pin near self two end part has otic placode, and described bearing pin two end part all arrange end cap, arrange O RunddichtringO between described end cap and otic placode.
The purpose of this utility model also realizes by following technological scheme:
Further, described in this scraper bowl pin shaft connection structure, bearing pin two ends outer circumferential walls cover has otic placode lining, and described otic placode is enclosed within otic placode lining, and described end cap is offered the first radial lubricating cup, the first lubricating cup is communicated to the space formed between end cap and pin roll end face.
Further, cover has front support inside otic placode described in this scraper bowl pin shaft connection structure and outside bearing pin.
Further, outside bearing pin described in this scraper bowl pin shaft connection structure, otic placode bushing locations is provided with front support lining, is enclosed within front support lining inside described front support two ends.
Further, front support described in this scraper bowl pin shaft connection structure offers the second radial lubricating cup, and the second lubricating cup is communicated to the space formed between front support and bearing pin, arranges oil sealing between described otic placode lining and front support lining.
Compared to prior art, the utility model has following beneficial effect:
When Joystick, stretching by oil cylinder, traction scraper bowl rotates around bearing pin together with otic placode, inject lubricant grease by the first lubricating cup and the second lubricating cup to lubricate, 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 scraper bowl pin shaft connection structure of the present utility model.
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 utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
With reference to accompanying drawing 1, this scraper bowl pin shaft connection structure forms primarily of end cap 1, otic placode 2, otic placode lining 3, front support lining 4, front support 5, first lubricating cup 6, bearing pin 7, oil sealing 8, O RunddichtringO 9, second lubricating cup 10.2 front support linings 4 are assemblied in front support 5 two ends respectively, and the first lubricating cup 6 is installed in front support 5, form supporting sleeve assembly; 2 otic placode linings 3 are assemblied on 2 otic placodes 2 respectively, form otic placode assembly; Second lubricating cup 10, O RunddichtringO 9 are installed on end cap 1, form end-cap assembly; Bearing pin 7 symmetry is assemblied in supporting sleeve assembly two front support lining 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 7 of the present utility model by 2 end caps 1 and the shutoff of 2 O RunddichtringOs 9 in the cavity be made up of otic placode lining 3, front support lining 4, front support 5, can synchronous axial system, avoid the Relative friction of bearing pin 7 and otic placode lining 3 and front support lining 4.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
