Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1 and Figure 2, described radial loaded mechanism includes radial loaded hydraulic cylinder piston rod 1, tested bearing 5, loading crossbeam 2, pull pressure sensor 8, hinged suspension ring 3, loads cover 6 and gland bonnet; Described radial loaded hydraulic cylinder piston rod 1 is articulated and connected with described loading crossbeam 2; Described hinged suspension ring 3 are set to two, and the structure of two described hinged suspension ring is identical and be hinged on the two ends of described loading crossbeam 2 respectively, and two described hinged suspension ring are symmetrically arranged structure on described loading crossbeam 2; Be provided with the pull pressure sensor 8 described in two, hinged suspension ring described with two are corresponding respectively arranges for pull pressure sensor described in two, one end of two described pull pressure sensor is fixed by threaded connection with corresponding hinged suspension ring respectively, the other end of two described pull pressure sensor is fixed by threaded connection on described loading cover 6, and is symmetrical arranged on described loading cover; By two the described pull pressure sensor arranged, while the measurement tested bearing being carried out to radial loaded power, carry out the measurement of bearing frictional torque; Described tested bearing 5 is arranged in the described central bore loading cover and have, and makes the outer ring of described tested bearing and the described endoporus overlapped that loads be interference fit; Described gland bonnet is set to two, and gland bonnet I 4, gland bonnet II 7 are connected to the two ends of described loading cover 6, is sealed described loading cover; The structure of gland bonnet I 4, gland bonnet II 7 is different; Described gland bonnet I 4 has axially extending bore, and main shaft, through gland bonnet I 4, connects the inner ring of tested bearing and drives inner ring to rotate; Described gland bonnet II 7 is by the external axial loading structure of screw thread; The top perforate of described gland bonnet I, described gland bonnet I 4, gland bonnet II 7, in order to carry out water pouring test to tested bearing; The top perforate that described loading is overlapped also loading laying temperature sensor and acceleration transducer in the top perforate of overlapping, realizes measuring the vibration of bearing and temperature rise situation in loading procedure.High-speed overload railway bearing is double-row roller bearing, needs to gather two paths of signals; In this embodiment, the described top perforate loading cover is four, in order to place two temperature sensors and two acceleration transducers respectively.
During work, radial loaded hydraulic cylinder piston rod 1 exports pulling force and pulls down loading crossbeam 2, load crossbeam 2 and pull down loading cover 6 by hinged suspension ring 3 and pull pressure sensor 8, because the loading inside of cover 6 and the outer ring of tested bearing 5 are fixed, namely this power be carried on bearing outer ring.The size of loading force equal two pull pressure sensor 8 and, when bearing inner race rotates, the size of moment of friction is the difference of two pull pressure sensor.This structure is measured while completing while loading radial force loading force and moment of friction, and water pouring test when can complete loading and the measurement function to acceleration and temperature rise signal.
