LOADING DEVICE Russian patent published in 2019 - IPC G01M13/02 

FIELD: test equipment.

SUBSTANCE: invention relates to test equipment and can be used for creation of pulling and pushing forces in power circuits of test benches, for calibration of force sensors, testing of materials for strength, as drives of power mechanisms, as jacks and presses. Loading device comprises a drive, a housing with a cover made with a hollow shaft, a gear reduction gear installed in the cover, the small gear of which is installed on the drive shaft, and large – on hollow cover shaft, screw gear installed in hollow cover shaft, wave reducer, rigid gear of which is fixed to housing, and flexible wheel – with screw of screw transmission, and deformation waves generator connected to large gear of gear reducer, note here that nut of screw gear in the form of sleeve is connected with cover by means of key connection while screw flange is installed between housing and second cover with possibility of rotation. Screw of screw transmission is made hollow, connected by internal thread with rod installed in it with possibility of axial movement and equipped with groove with key in it fixed in second cover of housing.

EFFECT: relatively large total stroke of the sleeve and rod in combination with compactness and relatively low weight of the device, cheapening the design and enlarging the field of application.
