Description
Technical field
The utility model belongs to the hoist technical field, relates in particular to a kind of hoist roller and speed reducer bindiny mechanism.
Background technique
At present, the reel of hoist and the relative position of speed reducer are fixed, when hoist is worked, reel directly upwards can be subject to larger power, some variations can occur in the position of reel under the effect of this power, make the axle center of the axle center of output shaft of speed reducer and reel not on same straight line, produce deviation, therefore for fear of this deviation, the output shaft of reel and speed reducer adopts drum coupling to flexibly connect, when the output shaft of speed reducer and the position between the reel change, by this drum coupling error is remedied, do not affect the transmission of power as far as possible.
But the structure of the drum coupling that uses on the hoist at present is comparatively complicated, and manufacture process requirement is higher, and price comparison is expensive, thereby has increased the cost price of hoist.
The model utility content
The purpose of this utility model is to provide a kind of hoist roller and speed reducer bindiny mechanism, be intended to solve in the prior art for the intensity that increases crane end carriage generally be to realize by the thickness that increases web, when increasing the thickness of web, will increase corresponding consumptive material, the problem that causes manufacture cost to increase.
The utility model is to realize like this, a kind of hoist roller and speed reducer bindiny mechanism, described bindiny mechanism comprises bearing, be disposed with the first riser and the second riser on the vertical direction on the described bearing, described the first riser is fixedly connected with the second riser, be provided with a mounting hole in the middle of described the first riser and the second riser, described speed reducer is arranged on the described bearing, the output shaft of described speed reducer is fixedly installed in the mounting hole between described the first riser and the second riser, the output shaft of described speed reducer passes described mounting hole and is fixedly connected with an end of described reel by the parts that are rigidly connected, the described parts that are rigidly connected comprise the axle connecting end that is connected with the output shaft of speed reducer, the reel connecting end that is connected with described reel and the stop component that prevents the output shaft axial motion of described speed reducer, the output shaft spline joint of described axle connecting end and described speed reducer, described reel connecting end is provided with annular flange flange, and described flange is fixedly connected with the reel end plate of described reel.
As a kind of improved plan, described stop component comprises the cover plate that is fixedly connected with the end of the output shaft of described speed reducer, and described cover plate leans on described reel connecting end, and the end of described axle connecting end leans on the boss of described output shaft.
In the utility model, described speed reducer is positioned on the described bearing, described speed reducer is fixedly installed on the described bearing and the output shaft of described speed reducer passes mounting hole between described the first riser and the second riser, speed reducer axially has certain degrees of freedom output shaft, corresponding change is done in the position that can drive speed reducer during the stressed bending of the first riser and the second riser, when hoist is worked, reel is subject to downward power descends the middle part of reel, move in the middle of reel at the reel two ends, because the output shaft of described speed reducer is fixedly connected with by rigid connector with described reel, therefore the connecting end of the motion of output shaft and rigid connector and reel is corresponding, the first riser and the second riser are as the fulcrum that supports reel one end, this moment is stressed to reel curving generation elastic strain, make the output shaft of speed reducer move also downward-sloping to the reel direction, because the manufacturing of rigid connector is comparatively simple and convenient, it is much lower that technological requirement and complexity are compared drum coupling, so that manufacture cost is much lower than drum coupling, manufacturing time is also shorter, thereby reduce the manufacture cost of hoist, and this mechanism also easily changes when damaging.
Description of drawings
