Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
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.
Claim 2
Independent Claim
107 words
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.
Claim 3
Dependent Claim
23 words
The devices of claim 1, wherein the source of lubricating material is a grease canister and the coupling is a grease gun coupling.
Claim 4
Dependent Claim
16 words
The device of claim 2, further comprising a conduit between the sensor and the grease canister.
Claim 5
Dependent Claim
18 words
The device of claim 3, wherein the sensor includes a first end in fluid communication with the conduit.
Claim 6
Dependent Claim
28 words
The device of claim 4, wherein the sensor includes a second end opposite the first end, the second end including threads for mating with threads on the coupling.
Claim 7
Dependent Claim
22 words
The device of claim 1, wherein the tube and transducer are surrounded by a non-conductive, shock absorbent material and a rigid casing.
Claim 8
Dependent Claim
23 words
The device of claim 1, further comprising an electric circuit connected to the transducer for converting the electrical signal to an audible signal.
Claim 9
Independent Claim
102 words
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.
Claim 10
Independent Claim
102 words
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.
Claim 11
Dependent Claim
15 words
The device of claim 8, wherein the source of lubricating material is a grease canister.
Claim 12
Dependent Claim
22 words
The device of claim 9, further comprising a coupling for receiving lubricating material from the sensor and introducing it into the bearing.
Claim 13
Dependent Claim
18 words
The device of claim 10, further comprising a conduit between the sensor and the source of lubricating material.
Claim 14
Dependent Claim
18 words
The device of claim 11, wherein the first end includes threads for mating with threads on the conduit.
Claim 15
Dependent Claim
18 words
The device of claim 12, wherein the second end includes threads for mating with threads on the coupling.
Claim 16
Dependent Claim
22 words
The device of claim 8, wherein the tube and transducer are surrounded by a non-conductive, shock absorbent material and a rigid casing.
Claim 17
Dependent Claim
19 words
The device of claim 8 further comprising an electronic circuit for converting the electrical signal to an audible signal.
