The device includes means defining a closed compartment containing a fluid and pressure-sensitive means communicating with said compartment. The compartment is arranged in thermal communication with a bearing of the vehicle so that increases in the temperature of the bearing cause increases in the pressure exerted by the fluid. The pressure-sensitive means is adapted to produce a signal when the pressure exerted by the fluid exceeds a predetermined threshold representing an over-temperature condition in the bearing. Preferably, the pressure-sensitive means takes the form of a plug normally closing an opening in the compartment, and a marker material, the plug and marker material being expelled when the pressure in the compartment reaches said predetermined threshold.

A thermal warning device (10) attaches to a wheel assembly of a railway car to detect high temperatures that may lead to bearing failure. In device (10), a temperature sensor (16) monitors the temperature of the wheel assembly and an electronic circuit (42) coupled to the temperature sensor (16) determines potential bearing failure based on the detected temperatures. Temperature sensor (16) adjustably extends into the wheel assembly to obtain accurate temperature readings. Electronic circuit (42) is situated away from the outer surface of the wheel assembly so as not to be subjected to heat from the wheel assembly and to freely dissipate heat produced by its own components. Upon determination of a warning condition, electronic circuit (42) transmits a warning signal to a wayside station or train crew. Optionally, the electronic circuit may include a wireless transmitter communicating with an in-cab receiver.

In a system to prevent train derailment due to axle failure resulting from journal bearing overheating, a thermal sensor continuously monitors the temperature of the bearing and activates the brake system when the temperature exceeds a predetermined level. A thermally-responsive element located in the journal bearing housing physically deforms to activate a power source. The resulting signal initiates an electro-explosive brake line venting mechanism, which punctures and vents brake line to stop the train. Several configurations of the thermal sensor and the power source are possible.

ROLLING BEARING CAGE

Номер: DE4124838A1
Принадлежит: INA Waelzlager Schaeffler oHG

A roller bearing race (1) for a machine component (4) which can both run freely on a shaft (3) and can be coupled thereto has pocketed rollers (2) and a slot (7) permitting its radial extension at a peripheral position. The race (1) consists of two interconnected material layers (5, 6) acting as a bimetal strip with different coefficients of expansion. This arrangement makes it possible for the race to expand radially on a rise in temperature and thus transfer a force with a peripheral component to the rollers (2) so that the bearing rollers (2) perform a slight rotation about the shaft (3) even if the shaft (3) and the pinion (4) are coupled. This prevents damage to the races by the rollers (2) at high radial forces.

Self-compensating anti-friction bearing clearance device

Номер: US4626111A
Принадлежит: Farrel Corp

A device for automatically adjusting the clearances in a roller bearing due to thermal expansion, constituting a tapered roller bearing having a dual track oppositely tapered inner race and a pair of single track tapered outer races, each outer race being in communication with a pair of coaxial, hydraulically loaded annular pistons, each of which translates in annular piston cylinders, supplied with hydraulic fluid. The hydraulic pressure of the fluid is maintained through an accumulator at a preselectable constant pressure to permit the outer races to translate axially, against the annular piston, as the inner race expands radially due to thermal expansion. Upon thermal contraction, the pressure forces the annular pistons axially toward the outer races, which, due to the taper of the races and the bearing elements, reduces the clearance created due to the thermal contraction.

A tapered roller bearing having its rollers arranged in two rows within an outer race and around an inner race contains a sensing device that radiates signals which reflect conditions within the bearing. In one embodiment, the outer race is unitary and the sensing device is wireless and self-powered and includes a mounting ring that is fitted to the outer race between the raceways along which the rollers roll. The ring has embedded within it several sensors for monitoring bearing conditions such as temperature and vibrations. The ring also contains a radio transmitter, a microprocessor to which the sensors are connected, and a power supply for producing the electrical energy required to operate the processor and the transmitter. The electric power is generated by means of electromechanical energy conversion using permanent magnets, armature winding and a target wheel that is captured between and rotates with the two cones. The transmitter converts conditions registered by the sensors and processed by the processor into radio signals which are received externally from the bearing. In another embodiment the unitary outer race has a groove which opens inwardly between the two rows of rollers, and the sensors, radio transmitter, processor, and power supply are located within the groove. In other embodiments the inner race is unitary and the sensors, radio transmitter, processor and power supply are carried by the inner race.
