Abstract
The utility model provides a novel hinge pin-end head locking sleeve structure for flexible connection of mechanical flexible arms. The novel hinge pin-end head locking sleeve structure comprises a first moveable arm end head base ear and a second flexible arm end head base head, which are connected together through a hinge pin; a locking sleeve is disposed between the first moveable arm end head base ear and the hinge pin; the outer wall of the locking sleeve is conical in shape; the inner wall, which is contacted with the locking sleeve, of the first moveable arm end head base ear is conical in shape; the angle between the inner wall of the first moveable arm end head base ear and the hinge pin is identical with the angle between the outer wall of the locking sleeve and the hinge pin; the locking sleeve is provided with an open slot; and the top part of the first moveable arm end head base ear is provided with an end head cap. The locking sleeve is compressed by the end head cap and the hinge pin cannot move in the first moveable arm end head base ear, so that the installation clearance of the overall flexible connection is reduced, wear is reduced, and the service lifetime is prolonged.
Description
Technical field
The utility model relates to the mechanical device technical field, particularly relates to a kind of novel mechanical swing arm flexible connection and sells the termination locking sleeve structure.
Background technology
As everyone knows, mechanical swing arm is multiplex in mechanical work, is mainly used in the back work that mechanization production is made, and mechanical swing arm just is equivalent to people's arm, mainly for the production of the work of making.In mechanical swing arm is flexibly connected, swing arm as digging machine, dress cultivation machine, to adopt the many places syndeton, the termination seat ear of the first swing arm and the termination seat head of the second swing arm, linked together by removable pin, due to needs movable and assembling, must reserve certain assembly clearance, in daily operation due to vibrations, swing, play between being flexibly connected.These assembly clearances are exactly the source of enhance faster wear, and the gap is larger, and wearing and tearing are just faster.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of novel mechanical swing arm flexible connection that can reduce assembly clearance to sell the termination locking sleeve structure.
the utility model is that the termination locking sleeve structure is sold in a kind of novel mechanical swing arm flexible connection, comprise the first swing arm termination seat ear and the second swing arm termination seat head, described the first swing arm termination seat ear and the second swing arm termination seat head link together by bearing pin, between the first swing arm termination seat ear and bearing pin, lock sleeve is set, described lock sleeve outer wall is tapered, the inwall that the first swing arm termination seat ear contacts with lock sleeve is tapered, and the inwall of the first swing arm termination seat ear is identical with the angle between lock sleeve outer wall and bearing pin with the angle between bearing pin, one open seam of described lock sleeve setting, the top of described the first swing arm termination seat ear arranges the termination end cap.
The utility model is that a kind of novel mechanical swing arm is flexibly connected pin termination locking sleeve structure, is provided with float grease seal on the rubbing surface of described the first swing arm termination seat ear and the second swing arm termination seat head.
Compared with prior art the beneficial effects of the utility model are:
Between the first swing arm termination seat ear and bearing pin, lock sleeve is set, described lock sleeve outer wall is tapered, the inwall that the first swing arm termination seat ear contacts with lock sleeve is tapered, and the lock sleeve inwall is identical with the angle between lock sleeve outer wall and bearing pin with angle between bearing pin.By the termination end cap, lock sleeve is compressed, make the bearing pin can't play in the first swing arm termination seat earrings, thereby can reduce the assembly clearance of whole flexible connection, machinery is when operation, the play radian of swing arm also drops to minimum, so just effectively increase mechanical application life, reduced wearing and tearing, improved mechanical application life.
Because the contact conical surface between lock sleeve inwall and a termination seat ear outer wall is identical with angle between bearing pin, dismantle also more convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
the utility model is that the termination locking sleeve structure is sold in a kind of novel mechanical swing arm flexible connection, comprise the first swing arm termination seat ear 1 and the second swing arm termination seat 2, described the first swing arm termination seat ear 1 and the second swing arm termination seat 2 links together by bearing pin 3, between the first swing arm termination seat ear and bearing pin, lock sleeve 4 is set, described lock sleeve outer wall is tapered, the inwall that the first swing arm termination seat ear contacts with lock sleeve is tapered, and the inwall of the first swing arm termination seat ear is identical with the angle 7 between lock sleeve outer wall and bearing pin with the angle 8 between bearing pin, one open seam of described lock sleeve setting, the top of described the first swing arm termination seat ear arranges termination end cap 5.
Between the first swing arm termination seat ear and bearing pin, lock sleeve is set during assembling, then use the termination end cap of the first swing arm termination to internal pressure, will be locked in the first swing arm termination seat ear together with lock sleeve bearing pin, make the bearing pin can't play in the first swing arm termination seat ear, thereby reduce the assembly clearance of whole active connection place, machinery is when operation, and the play radian of swing arm also drops to minimum, so just effectively increase mechanical application life, reduced wearing and tearing.
Be provided with float grease seal 6 on the rubbing surface of described the first swing arm termination seat ear and the second swing arm termination seat head.
The new novel mechanical swing arm of this practicality is flexibly connected in the structure of selling the termination lock sleeve, mechanical activity connection pivot pin to digging machine loader, crane, pump truck, bulldozer, land leveller all can arrange assembling the utility model, also have identical effect, assembly method is also similar, due to the large ting model disunity of articulating device of various machineries, the size of this lock sleeve and specification requirement body and decide.And structure and specification assemble method are basic identical, and it is identical to be effective, so all mechanical articulating devices are all the included contents of the utility model.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
Claims (2)
