Summary of the invention
The object of the present invention is to provide a kind of high-speed overload railway bearing testing table radial loaded mechanism, can measure accurately the radial force that is applied on the tested bearing, carry out simultaneously the measurement of bearing frictional torque, and measure the temperature of tested bearing and the measurement of vibration, satisfy the request for utilization of this testing table.
The technical solution used in the present invention is:
A kind of high-speed overload railway bearing testing table radial loaded mechanism, described radial loaded mechanism include radial loaded hydraulic cylinder piston rod, tested bearing, load crossbeam, pull pressure sensor, hinged suspension ring, load cover and gland bonnet; Described radial loaded hydraulic cylinder piston rod and described loading crossbeam are articulated and connected; Described hinged suspension ring are set to two, and the structure of two described hinged suspension ring is identical and be hinged on respectively the two ends of described loading crossbeam, and two described hinged suspension ring are symmetrically arranged structure at described loading crossbeam; Be provided with two described pull pressure sensor, two described pull pressure sensor respectively with two corresponding settings of described hinged suspension ring, one end of two described pull pressure sensor is fixedly connected with corresponding hinged suspension ring respectively, the other end of two described pull pressure sensor is fixedly connected and puts in described loading, and puts in described loading and to be symmetrical arranged; By two described pull pressure sensor that arrange, when being carried out the radial loaded force measurement, tested bearing carries out the measurement of bearing frictional torque; Described tested bearing is arranged in the central inner hole that described loading cover has, and the endoporus that the outer ring that makes described tested bearing and described loading are overlapped is interference fit; Described gland bonnet is set to two, and gland bonnet I, gland bonnet II are connected to the two ends of described loading cover, and described loading cover is sealed; Described gland bonnet I has axially extending bore, and main shaft passes the gland bonnet I, connects the inner ring of tested bearing and drive inner ring to rotate; Described gland bonnet II is by the external axial loading structure of screw thread; The top perforate of described gland bonnet I, gland bonnet II is in order to carry out water pouring test to tested bearing; The top perforate of described loading cover and in the top perforate that loads cover laying temperature sensor and acceleration transducer, vibration and the temperature rise situation to bearing that be implemented in the loading procedure measured.
The beneficial effect that the present invention has is:
When the invention solves testing table and need to finish the radial loaded of bearing, the problem of the measurement of radial loaded power and bearing frictional torque, the charger that proposes by the present invention can read the data of pull pressure sensor, the power sum of pull pressure sensor is radial loaded power, the difference of pull pressure sensor power is the moment of friction of bearing, but tested bearing is carried out the measurement of bear vibration and temperature rise situation at the upper end mounting temperature sensor and the acceleration transducer that load cover in loading procedure simultaneously.High-speed railway bearing test when the present invention can be used for the railway locomotive speed per hour and runs to 500km/h, also can be used for finishing when bearing carried out the radial loaded force measurement and carry out the measurement of bearing frictional torque, and the bearing test of simultaneously Vibration Condition and the temperature rise situation of bearing being measured in real time.
