Summary of the invention
Damages, transmission component transmission noise are big, the deficiency of poor stability for the transmission component that overcomes rigid joint in the existing height of packing compact regulating device easily produces, the invention provides a kind of simple in structure, assembling keep in repair easy, stable drive is reliable, noise is little, transmission component transships non-damageable friction type overload protection coupling.
The technological scheme that technical solution problem of the present invention is adopted is: a kind of friction type overload protection coupling; it comprises a body; it is characterized in that: described body is made up of shaft coupling body that is wholely set and hub formula body; have the shaft coupling hole of a band keyway on the described shaft coupling body; the coaxial respectively friction lumen that has on the both sides end face of described hub formula body; one pressure regulating cavity; on the diapire between friction lumen and the pressure regulating cavity, evenly have some pilot holes; some bolt correspondences are passed pilot hole; be positioned at the friction disk that has center hole on the bolt of friction lumen by the spacing suit one of its ailhead; assembling one ring gear between the diapire of this friction disk and friction lumen; the both sides of ring gear are respectively fitted with first brake pad; second brake pad; assembling one gear that is meshed with it in ring gear; have the axis hole of a band keyway on the wheel hub of this gear; the center hole of this wheel hub on friction disk stretches out friction lumen; be positioned on the bolt of pressure regulating cavity by having the baffle plate of center hole with the spacing suit one of the look nut of its screw-thread fit; the shaft coupling body stretches out pressure regulating cavity through its centre hole, is respectively installed with spring on the bolt between baffle plate and the pressure regulating cavity diapire.
Also cooperate a locking nut on above-mentioned and the bolt look nut screw-thread fit.
The present invention utilizes shaft coupling hole and the electric machine main shaft key connecting on the shaft coupling body, thereby the shaft coupling body, the hub formula body that drive one rotate synchronously, the bolt that is assemblied on the hub formula body two chamber diapires drives the friction disk rotation, the rotation look nut promotes the spring on the baffle plate compression screw rod, make the friction disk on the bolt apply positive pressure to brake pad, when just can driving ring gear, the frictional force increase rotates synchronously, ring gear drives with its meshed gears and rotates synchronously, and gear rotates with the miscellaneous part with its key connecting, realizes the moment of torsion transmission.When ball screw rose to limit position or other reasons and causes driving torque to increase overload unusually, the relative brake pad of ring gear skidded, and has protected motor and transmission component not to be damaged.The present invention is simple in structure, and the assembling maintenance is easy, and friction driving is steadily reliable, and noise is little.
