Abstract

PURPOSE:To prevent the damage of bearings and gears in transmission system due to the seizing of bearings by calculating bearing temperature and simultaneously the rising speed of the bearing temperature and raising an alarm when exceeding a preset value. CONSTITUTION:A plurality of temperature sensors 5, 6 are put near a single bearing 13 in a housing 1 having the bearing and abnormal heating of the bearing caused by overload on the bearing due to the failure of an oil supply pump or pipe blockage due to the invasion of foreign materials, the invasion of foreign materials into the bearing or the failure of the machine itself during operation, is detected. A controller 15 takes in the detected value of the sensors 5, 6 and caluculates the bearing temperature and the rising speed of the bearing temperature that is, the gradient of temperature change with time. A comparison judgment device 11 compares these values with a set temperature and set temperature gradient input in advance from a setting device 10 and raises an alarm to stop the operation when they exceed the set values.

However, in the bearing temperature monitoring apparatus and method as described above, the abnormality is judged only by the temperature of the bearing, and the bearing generates heat even during the normal operation to raise the temperature to some extent. Therefore, if the set temperature for detecting an abnormality is low, it will be judged that the abnormality is abnormal even in the normal state. Also, even if an abnormality occurs when the set temperature is raised, it takes some time for the bearing temperature to reach the set temperature, so the abnormality cannot be detected immediately and the operation will continue for a certain period of time after the occurrence of the abnormality. . Therefore, even if some abnormality occurs in the machine and the temperature rises, the abnormality cannot be detected immediately after that, and after a certain period of time, the abnormality alarm cannot be issued or the machine cannot be emergency stopped until the bearing temperature reaches the set temperature. There was a problem that the machine was damaged during the period from the occurrence of an abnormality to the stop of operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the following description, the same members as those in the above-described conventional example are designated by the same reference numerals, and the description thereof will be omitted. Only newly added members will be described. For example, as shown in FIG. 1, the temperature sensor device for the bearing may be installed at a plurality of positions near the bearing of the housing 1 in which one bearing 13 is mounted (or the frame when the bearing is directly mounted in the frame). When the temperature sensors 5 and 6 are attached and the machine is in operation, the bearing may be damaged due to failure of the oil supply pump or blockage of the pipeline due to foreign matter, foreign matter entering the bearing, and excessive load on the bearing 13 due to machine failure. When 13 heats up abnormally, the temperatures θ 0 and θ 1 measured by these temperature sensors 5 and 6 are input and calculated to calculate the bearing temperature θ and the bearing temperature rising speed, that is, the temporal temperature gradient dθ / dt. First, the set temperature θ B and the set temperature gradient R input in advance by the setting device 10 are compared by the comparison and determination device 11, respectively, and θ and dθ
When / dt exceeds θ B and R, it comprises a controller 15 which issues an alarm and issues an operation stop command. In this controller 15, the bearing temperature θ is calculated as follows. As shown in FIG. 3, the bearing temperature θ is measured from the temperatures θ 0 and θ 1 measured by the temperature sensors 5 and 6 embedded at points A 0 and A 1 near the bearing 13 as shown in FIG. (Θ−θ 0 ) / (θ 1 −θ 0 ) = L 2 / L, where L 1 is the distance between the measurement points A 0 and A 1 and L 2 is the distance between A 0 and A 2. 1 become thus bearing temperature theta is θ = θ 0 + L 2 ( θ 1 -θ 0) / L 1 and comprising also multiplied by the count k of actually be freely set in the calculation formula of the bearing temperature theta theta = k {Θ 0 + L 2 ((θ 1 −θ 0 ) / L 1 }), usually k = 1, and the degree of freedom of setting is set according to the situation, and the value of k is changed with a dial or the like to obtain the bearing temperature θ.
Can also be corrected to actually match. Also,
As shown in Fig. 2, the bearing temperature θ
And the temperature gradient dθ / dt, the bearing temperature θ and the temperature gradient dθ / dt and the controller 1 are calculated in advance.
Compared with the bearing temperature set value θ B and the temperature gradient set value R entered in 5, the temperature exceeds the set value θ B ,
Moreover, when dθ / dt exceeds the set value R, that is, θ ≧ θ
Simultaneously with B , when dθ / dt ≧ R, it is determined to be abnormal. As a result, the control device 15 issues an alarm and a command to stop the operation, and the machine issues an alarm and stops. Therefore, immediately after the time point t 1 when an abnormality occurs in the bearing, immediately after the abnormality is detected, the bearing temperature θ is a set value that defines the upper limit of the temperature allowed for the bearing.
There is no damaging the machine to stop the operation before reaching the t 2 time of the A. The arrangement of the temperature sensors for measuring the temperature of the bearing may be arranged in a direction perpendicular to the arrangement of FIG. 3 described in the above embodiment, as shown in FIG. Further, three or more temperature sensors for measurement embedded in the housing are used for one bearing, and the details are omitted here, but the temperature θ at the measurement points A 0 , A 1 , A 2 measured by each sensor Obtaining the temperatures of 0 , θ 1 , and θ 2 (for example, the temperature distribution is as shown in FIG. 6. Here, L 1 , L 2 , and L 3 are the measurement points A 0 to the measurement points A 1 and A 2 and the bearings. The bearing temperature may be calculated more accurately based on the distance to the position) and the theory of heat conduction. Further, as a simple type of the present invention, one temperature sensor is provided for each bearing and the estimated temperature of the bearing is not calculated, but the temporal temperature gradient at the measurement position and the set value for each of the measured temperatures are set. It can also be done by comparison.
