Description
Technical field
The present invention relates to coal-cutting machinery field, more particularly to a kind of traveling wheel overload protection arrangement is installed with machine walking
It takes turns the walking mechanism of overload protection arrangement and is installed with the coalcutter of the walking mechanism.
Background technology
Currently, in terms of the overload protection of walking wheel of coal cutter, the measure mainly taken has following several schemes：1, it uses
The scheme of torque axis connects a torque axis that is, on motor shaft, when transmission system is overloaded, by torque axle fracture come to passing
Dynamic system is protected, but this scheme, in torque axle fracture, whole driving parts between traveling wheel and torque axis are equal
By heavy duty, certain injury is had resulted in transmission system, to the protection of traveling wheel also unobvious；2, using electic protection side
Case, because there are apparent hysteresis qualitys for electic protection, so can still cause certain injury to transmission system；3, using torsion loop
Scheme, the program is effectively protected traveling wheel by using torsion loop, although this kind of overload protection scheme will not make
Entire transmission system is by heavy duty, but this scheme is still to reach protection mesh to destroy protection part as torque axis scheme
, new part is needed replacing after overload damage, of high cost and maintenance is inconvenient；4, using the scheme of friction limit square device, the party
Case limits square device to realize coal mining tractive unit overload protection by friction, its main feature is that protective device volume is larger, while protecting
Speed end, friction plate are easy to wear；5, using the scheme of the splined shaft with spron, the program be traction with traveling wheel it
Between transmit spron be set on the splined shaft of torque, play a protective role, this scheme replacement cost is high.
In conclusion how to provide it is a kind of it is simple in structure, cost is relatively low, maintenance is convenient and overload protection timely traveling wheel
Overload protection arrangement, walking mechanism and coalcutter, the technical issues of at those skilled in the art's urgent need to resolve.
