Abstract
The utility model relates to a kind of large pressing machine flywheel shaft bearing temperature checkout gear.Mainly solve existing large pressing machine flywheel shaft bearing temperature rise employing personal monitoring and accuracy rate is low, reaction slow thus the problem causing flywheel shaft Bearing Temperature and damage.It is characterized in that: the gripper shoe side of described entablature (1) has screw, and screw internal fixtion has temperature sensor B(9), the side of described flywheel supporting sleeve (3) is fixed with temperature sensor A(8 by screw).This large pressing machine flywheel shaft bearing temperature checkout gear can Real-Time Monitoring flywheel shaft bearing temperature, and detect accurately and reliably, too high in temperature is to control mair motor power supply, and the flywheel shaft having stopped to cause because temperature rise is too high grinds the accident of wound, bearing damage.
Description
Technical field
The utility model relates to machine tool field, specifically a kind of large pressing machine flywheel shaft bearing temperature checkout gear.
Background technology
Large pressing machine, when grinding car, often occurs that flywheel shaft bearing temperature rise is too high, and personal monitoring controls to cause flywheel shaft to grind wound not in time, twist off the problem with bearing locking, damage.Once there is this phenomenon, just main transmission part must be removed, the heavy parts of several tons easily, tens tons is well imagined from the difficulty that tens meters highly remove.Moreover, the strength member such as flywheel shaft, bearing needs to detect, and even scrap processing again or buy, not only large losses production time and the means of production, the precision for whole forcing press all will have an immense impact on.
Generally adopt now and avoid the way of flywheel shaft and bearing damage to be sending someone when grinding car, in the temperature rise of entablature place monitoring flywheel shaft bearing, to utilize laser thermodetector to detect by hand, finding that the operator of the too high notice of temperature rise before main controlling board controls to stop.The shortcoming of this way is, manual detection accuracy rate is not high, detects frequency low, and reaction slow motion, when carrying out eight hours and grinding car continuously, the phenomenon of flywheel shaft and bearing damage still happens occasionally.
Summary of the invention
In order to overcome existing large pressing machine flywheel shaft bearing temperature rise employing personal monitoring, accuracy rate is low, reaction slow thus the deficiency causing flywheel shaft Bearing Temperature and damage, the utility model provides a kind of large pressing machine flywheel shaft bearing temperature checkout gear, this large pressing machine flywheel shaft bearing temperature checkout gear can Real-Time Monitoring flywheel shaft bearing temperature, detect accurately and reliably, too high in temperature is to control mair motor power supply, and the flywheel shaft having stopped to cause because temperature rise is too high grinds the accident of wound, bearing damage.
The technical solution of the utility model is: a kind of large pressing machine flywheel shaft bearing temperature checkout gear, comprise entablature, flywheel shaft, flywheel shaft outside is connected with flywheel supporting sleeve by bearing A, the gripper shoe side of described entablature has screw, screw internal fixtion has temperature sensor B, and the side of described flywheel supporting sleeve is fixed with temperature sensor A by screw.
The utility model has following beneficial effect: owing to taking such scheme, flywheel supporting sleeve and entablature gripper shoe are provided with temperature sensor, Real-Time Monitoring can be carried out to the bearing temperature at two places, mair motor power-off is controlled when temperature is too high, effectively prevent because of temperature rise too high time cause the damage of flywheel shaft bearing and bearing, save a large amount of debug times, reduce the artificial waste and waste of material that bring because of accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The enlarged drawing at I place in Fig. 2 Fig. 1.
1-entablature in figure, 2-flywheel shaft, 3-flywheel supporting sleeve, 4-flywheel, 5-wet clutch, 6-bearing A, 7-bearing B, 8-temperature sensor A, 9-temperature sensor B.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of large pressing machine flywheel shaft bearing temperature checkout gear, comprise entablature 1, flywheel shaft 2, bearing B7 is provided with between the gripper shoe of entablature 1 and flywheel shaft 2, flywheel shaft 2 outside is connected with flywheel supporting sleeve 3 by bearing A6, and the flywheel shaft 2 of flywheel supporting sleeve 3 right-hand member is externally connected to flywheel 4, flywheel 4 right-hand member is provided with wet clutch 5.The gripper shoe side of described entablature 1 has screw, screw internal fixtion has temperature sensor B9, and the side of described flywheel supporting sleeve 3 has screw equally, and screw internal fixtion has temperature sensor A8, and temperature sensor A8 is near bearing A6, temperature sensor B9 is near bearing B7.
After mair motor starts, flywheel 4 starts to rotate, and wet clutch 5 carries out in conjunction with action, and flywheel driven axle 2 rotates.Simultaneously, temperature sensor A8 and temperature sensor B9 starts to carry out real time temperature detection, when detecting that any one bearing temperature in two place's bearings is greater than 57 degree, signal is sent to signal picker by humidity sensor 8, PLC controls wet clutch 5 and carries out disengagement action, and close mair motor power supply, fly wheel brake onset, flywheel 4 stops.
By the use of flywheel shaft bearing temperature checkout gear, effectively prevent because of temperature rise too high time cause the damage of flywheel shaft bearing and bearing, save a large amount of debug times, reduce the artificial waste and waste of material that bring because of accident.
