SITBS - The Self-Installing Thrust Bearing of Sliding |
|---|
The special self-installing thrust bearing
of sliding is ensuring the greatest possible contact of a surface of abutment
and of bearing for the account of self-installing of the adjusting mechanism is
developed at deviations of an axis of the shaft from vertical. It compensates
for technological errors and
eccentricity of the rotating part of all mechanism caused by misalignment of
axes of separate details, at that as misalignment with parallel by axes and
misalignment with cross by axes.
Submersible equipment of various type and purposes, designed for
extracting of petroleum and water from deep oil-well, and the drilling
equipment contains in a design the thrust bearing of sliding. The diametrical
restrictions of overall dimensions of submersible equipment do not allow the
applying of the device with independent segments, each of which densely would
adjoin to abutment, as in the known thrust bearing of sliding by Mitchell.
In design of the submersible electric
motor instead of such special devices use the ring from oil-resistant of
rubber, deformations dynamics of which do not provide uniform adjacency of
abutment and bearing on all surface, there is an asymmetric development, it is
especially on the large speeds and in the curved oil-well. It rises the moment
of resistance that especially has a negative effect for work at start-up and
reducing the time between failures. It is known that the cost of such failure
is very high.
Our experts have developed a design of the
self-installing thrust bearing of sliding, which allows for the account of the
self-installing mechanism to compensate technological errors, in particular,
arising from the eccentricity at misalignment of details of the submersible
device, and as misalignment with cross by axes.
It unloads all mechanism from dynamic
impacts, skews, jamming, raises reliability of the thrust bearing of sliding in
work, and provides contact of a surface abutment and bearing, equal to its
potential area at any errors of a design and technology within the limits of
technological errors.
The self-installing thrust bearing of sliding contains a frame and
bearing ring, rigidly established in it, abutment from antifriction material,
abutment as a washer rigidly established on the shaft, self-installing
mechanism.
The self-installing mechanism is executed
as two pairs diametrically located pins, established from each other under a
corner of 90 degrees and detail placed between a bearing ring and bearing. One
pair of pins is rigidly established in abutment with an opportunity of
maintenance it of rocking in an intermediate detail and with an opportunity of
maintenance of rocking and detail in a bearing ring concerning an axis of their
installation.
The unloading of the mechanism from
dynamic impacts, skews and jamming for the account of the self-installing
adjusting mechanism with the small diametrical sizes is provided. Such design
of the thrust bearing of sliding has high adaptability to manufacture and has
efficiency in comparison with known devices of a similar purpose. They have a
small metal consumption and high EFFICIENCY, creating conditions for a steady
oil wedge.
The enterprise KOPEN gives on the basis of
the available patent, of license for manufacturing use and in other designs and
sale SITBS.
