Rotary
support In the machine tool industry, the standard structure of the
slewing ring with high precision grade while applying preload to
eliminate the gap and reduce vibration. Radial
runaway and diameter tolerances range from one thousandth to one
thousandth of an inch (2.54 tan), are compact, have a small
cross-sectional dimension and can be as small as 50 mm in diameter (this
type of slewing steel Size is smaller than traditionally used heavy-duty slewing bearings). This prompted the designer to begin to reconsider the traditional slewing bearing configuration.
Spindle
shaft bearings for radial, axial and moment loads are mounted in two
sets of ball or roller slewing bearings. The arrangement is arranged by
connecting two sets of slewing bearings on the shaft at a longer
distance Set to achieve higher torque load capacity. However,
for such a configuration, due to the limitations of space and
installation complexity, it is difficult to adapt to new applications,
and this is the advantage of slewing bearings. The use of a set of slewing bearings instead of two sets of slewing
supports not only reduces the height of the device, but also simplifies
the component structure. Therefore, the slewing ring is particularly
suitable for use in new actuators in industrial automation.
The correct choice of slewing support depends on the requirements of load, stiffness, speed, size and rotation flexibility. The
user and the slewing bearing manufacturer discuss the applicability of
the design objectives and the slewing support, which will help to
optimize the performance of the system under the premise of low cost and
guarantee trouble-free work.
