Abstract
The utility model relates to a kind of coupling, comprises upper coupling, lower coupler and the attachment screw for being connected described upper and lower coupling and locking nut, at the sheathed elastomer of described lower coupler and attachment screw joint; Interior catch and outer baffle structure is respectively equipped with at described elastomer two ends; Described interior catch is between upper coupling, lower coupler connecting end portion.The elastomer structure of the utility model by being provided with in joint, when making it install connection, has certain resiliently deformable, increase the join strength between upper and lower coupling, be respectively equipped with interior catch and outer catch at elastomer two ends, limit the slip in the axial direction of upper and lower coupling, prevent from colliding between two half-couplings, reduce noise, improve the working life of coupling, also have simultaneously and change conveniently, rapidly, namely unload immediate shipment, effectively raise working efficiency.
Description
Technical field
The utility model relates to a kind of linkage structure, is specifically related to a kind of drive unit coupling be applicable on escalator and moving sideway product.
Background technique
In prior art, the Placement of coupling has a lot, generally most form by up and down axial organ, the pattern of ratchet is adopted to work in coordination between up and down axial organ, beam etc. is added between ratchet, the drawback of this Placement is that transmitted power is very little, if Spielpassung with great difficulty there is not noise.
Model utility content
The utility model object be in order to overcome the deficiencies in the prior art provide a kind of structure simple, install firmly, safe and reliable, there is the coupling of good economic and practical.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coupling, comprise upper coupling, lower coupler and the attachment screw for being connected described upper and lower coupling and locking nut, at the sheathed elastomer of described lower coupler and attachment screw joint; Interior catch and outer baffle structure is respectively equipped with at described elastomer two ends; Described interior catch is between upper coupling, lower coupler connecting end portion.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The coupling of the utility model scheme, by the elastomer structure be provided with in joint, when making it that connection is installed, there is certain resiliently deformable, increase the join strength between upper and lower coupling, interior catch and outer catch is respectively equipped with at elastomer two ends, limit the slip in the axial direction of upper and lower coupling, prevent from colliding between two half-couplings, reduce noise, improve the working life of coupling, also have simultaneously and change conveniently, rapidly, namely unload immediate shipment, effectively raise working efficiency; Also have and make coupling and the accurate concentric of mounted axle, there is the features such as balance quality is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of coupling of the present utility model;
Wherein: 1, upper coupling; 2, lower coupler; 3, attachment screw; 4, locking nut; 5, elastomer; 6, interior catch; 7, outer catch; 8, motor shaft; 9, upper connecting key; 10, reductor shaft; 11, connecting key.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1 of the present utility model can a kind of coupling, comprise upper coupling 1, lower coupler 2 and the attachment screw 3 for being connected described upper and lower coupling and locking nut 4, at described lower coupler 2 and the sheathed elastomer 5 in attachment screw 3 joint; Interior catch 6 and outer catch 7 structure is respectively equipped with at described elastomer 5 two ends; Described interior catch 6 is between upper coupling 1, lower coupler 2 connecting end portion.Coordinated by upper connecting key 9 between upper coupling 1 with motor shaft 8; Coordinated by lower connecting key 11 between lower coupler 2 with reductor shaft 10.
The utility model, by elastomer 5 structure be provided with in joint, when making it install connection, has certain resiliently deformable, increase the join strength between upper and lower coupling, be respectively equipped with interior catch 6 and outer catch 7 at elastomer two ends, limit the slip in the axial direction of upper and lower coupling, prevent from colliding between two half-couplings, reduce noise, improve the working life of coupling, also have simultaneously and change conveniently, rapidly, namely unload immediate shipment, effectively raise working efficiency; Also have and make coupling and the accurate concentric of mounted axle, there is the features such as balance quality is good.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
