Description
Technical field
The present invention relates to technical field of bearings more particularly to a kind of temperature elements for bearing.
Background technique
Sliding bearing is the important component of motor, under the conditions of fluid lubrication, two friction surfaces by hydrodynamic oil film every
Undeveloped life directly contacts, and supports the effect of the reliable and stable operation of rotating shaft system.
The service life of insulating materials and running temperature have close relationship in motor, to guarantee motor safety, reasonable use,
Need to monitor the temperature with measurement motor component.The temperature for accurately measuring some component, design and system to motor is improved
Technique is made, the quality for improving motor is very important.
For using the motor of sliding bearing, to prevent the electric current of output shaft generation in motor operation course to guide tile table
The babbit in face generates galvano-cautery, and guide tile is caused to damage, it usually needs one in the sliding bearing of motor is (general
Use two pieces) be designed to insulation system, i.e., it is separated between guide bearing seat and guide tile with insulating layer.In motor operation course,
The temperature for needing to detect guide tile, installs platinum resistance thermometer sensor, temperature element on guide bearing seat, and temperature probe is directly against guide tile
Thermometer hole bottom truly to measure the actual temperature of guide tile as far as possible.Therefore, temperature element also requires to be designed to insulation knot
Structure to avoid guide tile and guide bearing seat short circuit is caused after installation temperature element, and causes galvano-cautery to damage.Meanwhile to guarantee
Temperature element, which is popped one's head in, can resist the bottom of guide tile thermometer hole, it is desirable to which during the installation process, probe is inserted into temperature element
Depth is adjustable.But due to the limitation in motor space, temperature element sometimes be will be installed in bearing grease chamber lower part, this is just
It is noted that the structure of temperature element, prevents from affecting motor operation environment from the junction oil leak of temperature element and guide bearing seat.
In the prior art, there are two types of structures for the platinum resistance thermometer sensor, temperature element of sliding bearing:
The first is that temperature element and bearing are installed using fixed thread, and this structure installation sealing effect is good, but pops one's head in
Insertion depth is unadjustable, and probe has been against the bottom of guide tile thermometer hole after not can guarantee temperature element installation, and pops one's head in
It is on-insulated with installation screw thread；
It is for second that temperature element and bearing are installed using cutting ferrule screw thread, probe insertion depth is adjustable, and when installation can protect
Card probe has been against guide tile thermometer hole bottom, can also increase insulation sleeve in cutting ferrule to realize that probe and installation screw thread are exhausted
Edge, but the sealing effect after installation is bad, and Leakage can be generated when being mounted on grease chamber bottom.
