LOCKING DEVICE FOR TAKING UP THE AXIAL LOAD OF SHAFT Russian patent published in 2022 - IPC F16B19/02 F16B21/00 

FIELD: machine building.

SUBSTANCE: invention relates to fasteners, namely to devices for fixation, mainly, of shaft-bushing parts. Locking device contains a limiting bushing placed on the shaft and taking up the load acting on the shaft in the direction of its axis. In the shaft on the side of the surface of the limiting bushing, opposite to the surface taking up the axial load, there is a hole perpendicular to the shaft axis, in which there is a pin for fixing the limiting bushing and interacting with it. In the pin perpendicular to its axis there are parallel holes for the rod elements fixing the position of the pin relative to the shaft, wherein the parallel holes are located at equal distances from the ends of the pin and at a distance exceeding the diameter of the shaft, and are oriented parallel to the surface of the limiting bushing, wherein the length of the pin is determined from the ratio. Pin is fixed by a wire passing through at least one of the pin holes and completely enclosing the shaft.

EFFECT: simplifying the design of the device, conditions of its assembly and maintenance, as well as providing the possibility of longitudinal movement of the shaft and its rotation, which will make it possible to expand the field of application of the device.
