skf bearing of the shaft design concepts and Failure

  1. Shaft failure modes: a major lack of strength due to fatigue and the fatigue crack bamboo fish trap, due to insufficient strength of static plastic deformation or brittle bamboo fish trap crack, abrasion, exceed the allowable range of deformation and vibration. Slewing bearing Engineer
2-axis should be designed to meet the following criteria:
(1) according to the axis of the working conditions, production volume and economic principles, selecting suitable materials, blank form and heat treatment method.
(2) according to the axis of the force, the shaft part is installed, with the size and positioning, the axis of the processing methods and other specific requirements, determine the rational structure of shaft shape and size, namely the structural design of the axis.
(3) shaft strength calculations or check. A large force on the elongate shaft (such as worm shaft) and high axial stiffness requirements, but also for stiffness calculation. In the work under the high-speed shaft, due resonance dangerous and should be carried out vibration stability calculations.
