| description | The article presents the results of studies of profile joints of mechanisms and
machines for rigidity and strength. The device is based on the use of fixed and
movable profile connections designed to transmit torque. Profile joints with a
guaranteed gap are considered, made on the basis of an equiaxial contour of the
P3, P5 type and a curved contour of the PC4 type, which have received the most
widespread introduction in the nodes of metal-cutting machines and other machines
manufactured in Russia, as well as Hungary, Germany and the DPRK.
Using a well-known technique designed to assess the stress-strain state (VAT) of
the parts of profile joints, calculations are performed according to the criteria
of operability for strength and stiffness of hubs (bushings) with different wall
thicknesses. The analysis of the results of the calculation of strength and stiffness is
carried out using the example of the P3 profile. When stretching the hub from the
action of spacer forces, the geometric shape, the nominal size of the covered part,
the wall thickness of the covering part, as well as the magnitude of the external load
transmitted by the connection in static are taken into account. The permissible values
of the thickness of the walls of the hub (bushings) of the joint are determined to
ensure the rigidity of the hub under tension from the action of external loads. As a
result of the research, the influence of the thickness of the hub walls for the studied
shapes of the joint parts on the values of the transmitted torque is established. For
example, a change in the thickness of the hub wall from 15 to 3 mm for a normal
range of shaft mounting diameters causes the sleeve to stretch radially up to 50
microns in the range of transmitted torques from 5 to 600 Nm. |
