Abstract
A device for monitoring vibration of a bearing to assess whether other service is required. The device is adaptable for use with conventional grease guns and can be used simultaneously with lubrication of a bearing. The device includes an electric circuit and headphones which enable the wearer to "listen" to the bearing. Depending on the "bearing noise" that is heard, maintenance personnel can assess what further lubrication is required and what service is needed.
Claims15
A device for assessing whether a bearing requiring periodic lubrication and having a fitting for receiving lubricating material requires service, the device comprising:
- a coupling for introducing lubricating material into the bearing from a source of lubricating material;
- and a sensor attached to the coupling for detecting vibration and producing an electric signal indicative of the vibration of the bearing when the coupling is mated with the bearing wherein the sensor includes a tube for carrying the lubricating material and a transducer in contact with the tube for detecting the vibration of the bearing through the tube and producing the electric signal in response to the vibration.
A device for monitoring vibration in a bearing requiring periodic lubrication comprising:
- a sensor for detecting vibration in the bearing and producing an electrical signal indicative of the vibration, the sensor including a first end for receiving lubricating material from a source of lubricating material and a second end for dispensing the lubricating material from the sensor wherein the sensor includes a tube between the first and second ends for carrying the lubricating material and a transducer in contact with the tube for detecting the vibration of the bearing through the tube and producing the electrical signal in response to the vibration.
