Technical background
Motor is the important driving force that modern industry is produced, and is petrochemical complex, the visual plant that uses in a large number of coal mine, the basic activity such as electrical production.Bearing is applied very extensive in rotating machinery, its running status often directly has influence on the precision of entire machine, reliability and life-span, therefore, to bearing carry out effective condition monitoring and fault diagnosis for raising equipment operational reliability and utilization ratio significant.In addition, build digital plant, intelligent plant proposes urgent demand to the condition monitoring and fault diagnosis technology that development is advanced.Have many forms when bearing defect or fault, as vibration & noise increase, temperature rising, structural failure etc., these signals have all contained bearing fault information.Temperature height is the parameter reflecting that bearing quality is the most visual and understandable, carries out the important means that temperature survey is motor status monitoring and fault diagnosis.
Because bearing is arranged on motor housing inside, real bearing temperature not easily obtains, therefore, Most current generally can only select for the manual detection of motor bearings temperature or on-line monitoring the surface temperature measuring bearing (ball) cover or shell, indirectly the quality of reflection bearing.This measuring method affects comparatively large by the factor such as external environment condition, electric machine structure, cannot obtain real bearing temperature, validity and the accuracy of measurement result are had a greatly reduced quality, and are unfavorable for the correct judgement to motor bearings running status.Therefore, design a kind of installation that can measure bearing true temperature easily temperature sensor there is great practical value and application prospect.
The utility model solves this problem targetedly.
Utility model content
The utility model will provide a kind of novel can measure bearing true temperature and have the motor bearings temperature sensor of grease adding function, and to help to solve, motor bearings temperature survey is forbidden, the problem of in-site installation inconvenience.This temperature sensor is mainly used in measurement and the grease adding of the rotary equipment bearings temperature such as motor, has and measures the advantages such as accurate, simple for structure, easy for installation.
For solving the problem, the technical solution adopted in the utility model is as follows: can the bearing temperature sensor of grease up, metal tube (3) is fixed on the bearing grease filling hole on motor bearing end cover by lower thread (4), top screw thread installs tee pipe coupling (2), temp probe (5) is through behind the bearing grease filling hole on metal tube (3) and motor bearing end cover, touch bearing outer ring, the signal wire (8) of temp probe (5) is drawn by the side opening of tee pipe coupling (2), and by fastening (7) crush seal pad (6) fixed signal line (8), grease adding mouth (1) is threaded connection and is fixed on tee pipe coupling (2) top.
In technique scheme, preferably, lower thread (4) external diameter of metal tube (3) is identical with the bearing grease filling hole diameter of screw on motor bearing end cover.
In technique scheme, preferably, tee pipe coupling (2) internal diameter is not less than the internal diameter of metal tube (3).
In technique scheme, preferably, temp probe (5) diameter is less than the internal diameter of metal tube (3), and the gap between temp probe (5) and metal tube (3) inwall is not less than 1mm.
In technique scheme, preferably, grease adding mouth (1) diameter of screw is identical with tee pipe coupling (2) internal thread diameter.
In the utility model, due to temp probe (5) is touched bearing outer ring by the bearing grease filling hole on metal tube (3) and motor bearing end cover, and draw by having drawn signal wire (8) in metal tube (3) upper design tee pipe coupling (2) and grease adding mouth (1) has been installed, not only achieve the Measurement accuracy of bearing true temperature, and there is bearing grease filling function, achieve good technique effect.
Accompanying drawing explanation
Fig. 1 be described in the utility model can the bearing temperature sensor structure cut-open view of grease up.
Fig. 2 be described in the utility model can the bearing temperature sensor structural representation of grease up.
In Fig. 1 and Fig. 2,1 is grease adding mouth; 2 is tee pipe coupling; 3 is metal tube; 4 is metal tube lower thread; 5 is temp probe; 6 is gasket seal; 7 is fastening; 8 is signal wire.
Below by embodiment, the utility model is further elaborated, but is not limited only to the present embodiment.
Embodiment
[embodiment 1]
