Abstract
The utility model provides an anti-swing large-torque connection structure used on an excavator. The connection structure comprises a left lug plate, a right lug plate and a main sleeve, wherein sliding bearings are respectively arranged in connection holes of the left lug plate and right lug plate; a left hinge pin and a right hinge pin are respectively mounted in holes of the sliding bearings; the ends, of the left and right hinge pins, extending out of the space between the left and right lug plates are designed into conical structures; a threaded hole is formed in the conical end surface of the left hinge pin, and a through hole is formed in the right hinge pin; conical holes are formed at the openings at two ends of the main sleeve and are matched with the conical structures of the left and right hinge pins; a fastening bolt is arranged between the left and right hinge pins. The connection structure adopts a simple machining process, is convenient to mount and reliable in matching; the distance between the sliding bearings is increased in a limited space; load on the sliding bearings during swing is reduced.
Description
Technical field
The utility model relates to a kind of excavator, more particularly relates to anti-swing high-torque syndeton on a kind of excavator.
Background technology
The syndeton of carrying high-torque in traditional excavator is all to adopt bearing pin otic placode to be fixedly connected, the structure that mother set and bearing pin are actively coupled, the two ends that is to say bearing pin are directly fixedly connected with the hole interference fit on otic placode, and adopt sliding bearing to be connected between bearing pin and mother set.Structural limitations due to excavator, space between its otic placode is narrower and small, the mother set length of bearing load can not strengthen, so mother set two ends sliding bearing can bear great radial load when operation partly swings, has had a strong impact on the application life at bearer connection position.And when mounted, bearing pin is difficult to put in the connecting hole of otic placode.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and anti-swing high-torque syndeton on a kind of excavator that bears larger load is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: anti-swing high-torque syndeton on a kind of excavator, comprise left and right otic placode and mother set, in the connecting hole of described left and right otic placode, be respectively arranged with sliding bearing, in plain bearing bore, be separately installed with left and right bearing pin, conical structure is arranged in one end that described left and right bearing pin stretches out between the otic placode of left and right, and the cone end end face of described left bearing pin is provided with screwed hole, and described right bearing pin is provided with through hole; The place, aperture, two ends of described mother set arranges taper hole, and described taper hole matches with the circular cone of described left and right bearing pin, between described left and right bearing pin, fastening bolt is set.
In such scheme, the bearing in described left and right otic placode connecting hole is sliding bearing.
On a kind of excavator of the utility model, compared with prior art, its beneficial effect is anti-swing high-torque syndeton:
1, this kind of structure processing technology is simple, easy for installation, coordinates reliable.
2, this syndeton has strengthened the spacing between bearing in limited space, has reduced the load that while swinging, bearing bears.
Accompanying drawing explanation
Accompanying drawing is the structural representation of anti-swing high-torque syndeton on a kind of excavator of the utility model.In figure: 1. left otic placode, 2. sliding bearing, 3. left bearing pin, 4. fastening bolt, 5. mother set, 6. auris dextra plate, 7. right bearing pin, 8. screwed hole, 9. through hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, anti-swing high-torque syndeton on a kind of excavator of the utility model is further described:
Accompanying drawing is the structural representation of anti-swing high-torque syndeton on a kind of excavator of the utility model.In figure, this syndeton comprises left otic placode 1, auris dextra plate 6 and mother set 5, in the connecting hole of left otic placode 1, auris dextra plate 6, be respectively arranged with sliding bearing 2, sliding bearing 2 endoporus are separately installed with left bearing pin 3 and right bearing pin 7, conical structure is arranged in one end that left bearing pin 3 and right bearing pin 7 stretch out between left and right otic placode, the cone end end face of left bearing pin 3 is provided with screwed hole 8, and right bearing pin 7 is provided with through hole 9; The place, aperture, two ends of mother set 5 arranges the taper hole matching with the circular cone of left and right bearing pin, between left bearing pin 3 and right bearing pin 7, fastening bolt 4 is set.
In the structure of this syndeton, mother set 5 is enclosed within the axis of cone of bearing pin, in the through hole 9 of fastening bolt 4 from right bearing pin 7, passes, and is tightened in the screwed hole 8 on left bearing pin 3, along with tightening of fastening bolt 4, mother set is fixed on two bearing pins tightly becomes as a whole.Like this, strengthen the spacing between sliding bearing, also just increased the carrying moment of bearing pin accordingly, reduced the load that while swinging, bearing bears.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the method for above-mentioned announcement and technology contents to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, still belong in the scope of technical solutions of the utility model.
Claims (2)
1. anti-swing high-torque syndeton on an excavator, comprise left and right otic placode and mother set, it is characterized in that: in the connecting hole of described left and right otic placode, be respectively arranged with bearing, in dead eye, be separately installed with left and right bearing pin, conical structure is arranged in one end that described left and right bearing pin stretches out between the otic placode of left and right, the cone end end face of described left bearing pin is provided with screwed hole, and described right bearing pin is provided with through hole; The place, aperture, two ends of described mother set arranges taper hole, and described taper hole matches with the circular cone of described left and right bearing pin, between described left and right bearing pin, fastening bolt is set.
