Abstract
The utility model relates to a safety protection type membrane flexible shaft coupling. On the shaft coupling which is composed of a middle nodule, a membrane, double wheels and screw bolts, a protective cover which can prevent the membrane and the middle nodule flange from flying out is fixedly arranged on the double wheels, the gap between the protective cover and the middle nodule flange is tiny so that the membrane and the middle nodule flange can not fly out and the protective cover can not be damaged when failure is generated, and therefore, the unsafe factor of the existing membrane flexible shaft coupling is eradicated.
Description
The utility model relates to a kind of safety protection type diaphragm flexible shaft coupling that has protective housing.
Diaphragm flexible shaft coupling of the prior art as shown in Figure 2, it by middle segmentum intercalaris 1, diaphragm 2, to take turns 4 and bolt 3 form, wherein diaphragm 2 is made by special stainless steel sheets, it can absorb the compound stress that various displacements produce in the unit, it is big to have compensation ability, shock-absorbing, the advantage that the shock insulation ability is strong, its deficiency is, in the running, owing to metal fatigue or because fortuitous events such as generation seizes, cause in the coupling segmentum intercalaris to be twisted off or diaphragm damages and the accident of hurting sb.'s feelings that flies out happens occasionally, exist serious unsafe factor.
The purpose of this utility model is to provide a kind of advantage that had both had diaphragm flexible shaft coupling, coupling as safe as a house again.
Technical solution of the present utility model is, on the basis of existing diaphragm flexible shaft coupling, can prevent the protective housing that it flies out the outer rim setting of its diaphragm and middle segmentum intercalaris flange plate.
In this programme, protective housing is to be fixedly mounted on the wheel with screw.
In this programme, the gap between protective housing and the middle segmentum intercalaris flange plate outer rim is 1-1.5mm.
The utility model has the advantages that, because the protective housing that can stop it to fly out outer rim being provided with of diaphragm and middle segmentum intercalaris flange plate, particularly the gap between protective housing and the middle segmentum intercalaris flange plate is very little, therefore, both made coupling occur being twisted off or diaphragm such as is damaged at situation, also will be limited in rotation synchronously with it in the protective housing, and also can not produce very big surge guard cover, protective housing can not be damaged, thereby has played the safety protection effect, can fundamentally eliminate the unsafe factor in the existing diaphragm flexible shaft coupling, have simple in structure, easily implement, cost is low, safe and reliable advantage.
Accompanying drawing 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of existing diaphragm flexible shaft coupling.
Below in conjunction with accompanying drawing the utility model is described in detail.1 is middle segmentum intercalaris among the figure, and 2 is the diaphragm made from stainless steel sheets, and 3 is fixing bolt, and 4 is that their structure and existing diaphragm flexible shaft coupling are identical to wheel.The utility model special way structurally is to have added a protective housing 5, covers on the outer rim of diaphragm and middle segmentum intercalaris flange plate, prevents that its situation of hurting sb.'s feelings that flies out from taking place.In the present embodiment, protective housing 5 is to become to have the matrix cover cap of center hole with steel by drawing and forming or cutting, from coupling two ends the wheel side is enclosed within on segmentum intercalaris flange plate and the diaphragm, and is fixed on taking turns with screw.Gap 6 between protective housing 5 and the middle segmentum intercalaris flange plate outer rim is controlled between the 1-1.5mm.Gap 6 should be the smaller the better, so both coupling was met accident, diaphragm and middle segmentum intercalaris flange plate still are limited in rotation jointly with it in the protective housing, fly not go out, and very little because of gap 6, can not produce impact force to protective housing, protective housing can not go to pot, can play reliable protective action, thereby fundamentally eliminate the unsafe factor in the former diaphragm flexible shaft coupling.
Claims (3)
1, a kind of safety protection type diaphragm flexible shaft coupling is formed by middle segmentum intercalaris 1, diaphragm 2, bolt 3 with to taking turns 4, it is characterized in that flange plate outer rim at diaphragm 2 and middle segmentum intercalaris 1 is provided with can prevent its protective housing that flies out 5.
2, safety protection type diaphragm flexible shaft coupling according to claim 1 is characterized in that protective housing 5 is to be fixedly mounted on taking turns on 3 with screw.
3,, it is characterized in that the gap 6 between the outer rim of protective housing 5 and middle segmentum intercalaris flange plate is 1-1.5mm according to claim 1 or 2 described safety protection type diaphragm flexible shaft couplings
