The standard for measuring temperature is referred to as the temperature scale. It is the starting point (zero point) of the reading to determine the temperature and the basic unit (degrees) of the measured temperature. First, commonly used "temperature standard" 1. Fahrenheit temperature scale (° F ) : The Fahrenheit temperature scale stipulates that the water has a freezing point of 32 degrees and a boiling point of 212 degrees at one atmosphere. The zero point and the boiling point are equally divided into 180 equal parts. Each aliquot represents a degree of Fahrenheit and is expressed in ° F. 2. Celsius temperature scale (°C): The Celsius temperature scale is divided into 100 equal parts between the freezing point and the boiling point. Each aliquot is called a degree Celsius. Expressed in °C. The freezing point is specified to be zero degrees ( 3. The conversion relationship between Celsius temperature (°C) and Fahrenheit temperature (° F ) is: Second, the international practical temperature scale In addition to Celsius temperature, there is also a Kelvin temperature scale. The Kjeldahl temperature scale stipulates that the temperature at which the molecular operation stops is absolute zero. Its symbol is represented by " T " and its unit is Kelvin. The unit symbol is indicated by K. The conversion relationship between the Kjelda temperature scale and the Celsius temperature scale is: t=TT 0
Cross Roller Bearing is a special type
bearing. Because of the inner ring or outer ring were separated, after loading
the roller and the cage, it is fixed with the cross roller shaft ring to
prevent the separation, so the operation is simple when installing the cross
roller shaft ring. Since the rollers are intersected, only one set of cross
roller bearings can withstand the load in each direction, which is three to
four times more rigid than the traditional model. At the same time, because the
inner ring or outer ring of the cross Roller Bearing is a two-part structure,
the bearing clearance can be adjusted, and even if it is preloaded, it can
obtain a high-precision rotary motion. Moreover, because of its special
structure, it is commonly used in industrial robots as joint bearings.
The classification and model series of cross roller bearings are below:
RB type (outer ring segment)
RB series models for cross roller bearing, basic, inner and outer ring
size is minimal to miniaturization, its structure is the outer ring is divided,
the inner ring design is an organic whole, the inner ring spinning of high
precision parts suitable for requirements.
RE type (inner ring segment)
The RE series is a new type of XRB design concept, which is the same size
as the XRB type.The structure of the inner ring is the split type and the outer
ring is one design, which is suitable for the parts with high rotating
precision of outer ring.
RU type (inner and outer circle)
The RU series model is not required to be fixed flange and support base
due to the processing of mounting holes.In addition, due to the adoption of the
integrated inner and outer ring structure of the belt, the installation has
little effect on the performance, thus achieving stable rotation precision and
torque.Can be used for outer ring and inner ring rotation.
RBC type (outer ring segment)
The RBC series model (corresponding to the CRBC series of IKO company) is
composed of the outer ring is the split type, the inner ring is one design, and
the belt is fully loaded with roller bearings.Suitable for high rotation accuracy
of inner ring.
CRBH type (inner and outer ring)
CRBH series model, outer ring and outer ring are integral structure, used
for outer ring and inner ring rotation.
RA type (outer circle segmentation, ultrathin type)
The RA series model is the compact type that reduces the thickness of RB
and outer ring to the limit.Suitable for areas with light weight and compact
design, such as rotating parts of robot and manipulator.
SX type (outer ring segment)
The structure of SX series is similar to that of RB series. The outer ring
is a two-part structure, which is designed with three spring card rings and the
inner ring, which is suitable for the place where the inner ring has high
rotation precision.
XRU08 type (inside and outside)
XSU08 series is similar to the RU series, and the inner and outer rings
have been machined with holes, so no fixed flange and support seats are
required.Due to the adoption of the integrated inner and outer ring structure,
the installation has little effect on the performance, thus achieving stable
rotation precision and torque.Can be used for outer ring and inner ring
rotation.
