Description
Technical field
This utility model relates to MACHINERY JOINT field, particularly relates to a kind of shaft coupling.
Background technology
When two mechanical axis systems are joined directly together, one be driving shaft, one be driven shaft.Therebetween axle system must be strictly concentric, otherwise can produce very big mechanical force in rotation during Difference angles, to such an extent as to damage frame for movement, even not rotate, whole mechanism is damaged.But it practice, two axle systems separately are impossible free from error with one heart.In order to solve this problem, do not allow between two axle systems in principle to adopt rigidity to be directly connected to, but adopt one to have elastic shaft coupling between two axle systems and connect.This shaft coupling is divided into two large divisions, is connected with driving shaft and driven shaft respectively.And be by one, there are elastic parts to link together between two large divisions.So, when two axles tie up to rotation, if there being small nonconcentricity, by the deformation of elastomeric element, dissolve the considerable damage mechanical force produced in rotation process when being rigidly connected.
In generally traditional shaft coupling, above-mentioned flexible member is all made with the reasonable metal material of deformation behavior, except the effect realizing elastic deformation, also needs the effect as structural support elements.And when doing elastic deformation, will have certain power or moment, thus limit application.Additionally in use, although installation dimension tolerance is not as strict, but when installation deviation is excessive, unallowed error, precision can still be produced inadequate.

Described collar half-via is provided with dismountable for the rubber bar with sensor chassis contact, and described card ring through hole is provided with dismountable contour screw for threadeding with sensor casing.The sensor casing of angular transducer is provided with six screws and three through holes, and three screws in six screws are for being connected with sensor end cap.And three card ring through hole on collar are screwed in corresponding three screws in sensor casing by contour screw, three rubber bar two ends are inserted in the through hole of collar half-via and sensor casing respectively.Just and angular transducer formation resilient connection, wherein the effect of adjustment is just played in the deformation of rubber bar to such shaft coupling.This utility model can according to the transmission size of torque, physical dimension, specific design rubber bar.
It is provided with rubber blanket between described collar and described contour screw.
Described collar adopts metal material to make.
In this utility model, rubber bar and rubber blanket simply play resilient connection effect, do not adjust with one heart for small between drive end and driven end.Rather than as metallic elastic component in tradition shaft coupling, both done the use of elastic deformation, also to have taken into account the use of structure support；The power or the moment that so need are only small.Meanwhile, it is upper very convenient that such structure makes the installation form of sensor design, and the precision of installation dimension completes mainly by structural member, and flexible member is not involved in, and can realize accurate installation completely, and transmitting accuracy is significantly high.
It is trapezoidal opening that the one side of described collar is provided with cross section, and described opening is structure wide outside and narrow inside, and the medial surface of described opening is provided with and the described collar open hole to side UNICOM；
Being positioned at described opening and the described collar on side is provided with rectangular opening, rectangular opening described in described open hole UNICOM, described rectangular opening is provided with the rectangular nut being mated；
It is trapezoidal chock that described opening is provided with dismountable cross section, described chock matches with the opening on described collar, described chock is provided with chock through hole along trapezoidal short transverse, and described chock through hole is provided with the soket head cap screw that dismountable and described rectangular nut is threadeded.When this utility model uses, first chock is placed in opening, by soket head cap screw through after chock through hole, threadeds with to the rectangular nut of side.Trapezoid-shaped openings when soket head cap screw is tightened, on chock meeting spreading collar so that collar size slightly becomes big, realizes stretching better, fixes.
Described card ring through hole and described collar half-via are spaced apart by described collar, and a side of described opening is described card ring through hole, and another side is described collar half-via.
It is provided with circlip between described chock and described soket head cap screw.
Beneficial effect: owing to have employed technique scheme, this utility model is applicable between two axle systems the torque hour transmitted, such as the device such as rotary transformer or encoder, its simple in construction, easy for installation, it is achieved that the installing hole of the size of masters and driven side is closely, coordinate accurately.
