In some large and medium-sized rotating equipment, the same kind of high-precision components are used, that is, bearings. In
addition, bearing bushes are required to adhere to the outstanding
smoothness of the composite bearing, which means that smoothness is one
of the necessary conditions for bearing bushes. As for most bearing
bushes, they are smoothed by a device capable of supplying a large
amount of smooth oil. The smooth way of bearing bushes is called full smoothness.
However,
in fact, the use of a bi-metallic connecting rod bushing for the
pressurizing and smoothing of the bearing bush will provide a better
effect and will prevent the equipment from appearing faulty. The filter
screen will be clogged, and smooth oil will be injected into the journal
and bearing surface due to the added smoothness. Touch conflicts. Of course the demand is clear, this smooth approach will make the cost increase.
Has
increased the smoothness of the addition of the bearing bush, it would
have to mention the oil ring, a smooth method to assist the supply of
pressurized equipment, general JDB graphite copper sleeve in some large
and medium speed motors are used in the single selection oil ring Smooth, as long as it is on the medium and high speed motor, it will
combine the pressurized oil supply and the oil return ring composite
smoothly.
From
past experience, it can be seen that when the speed of the bearing is
lower than the medium speed, the oil slinger becomes the main method of
oil supply. This type of part is usually made of copper raw material, and its ring
diameter is smaller than the shaft diameter, so it is only required to
simply put it on the shaft, and the work can be performed by determining
its orientation from the groove of the upper tile of the bearing bush.
In
the bearing bush, the lower part of the oil-stripping ring is immersed
in the bearing housing oil tank. When the shaft is in the rotating
state, the drag force generated by it will promote the rotation of the
oil-stripping ring, and will take the oil in the bearing box and splash
it. Bearing pads four weeks, then reach a smooth effect. This proves that the oil-stripping ring can also play the role of cooling and maintenance in the bearing shell.
