Abstract
Abstract A bearing is disclosed that includes a support housing or casing in which is located a body of elastomeric material. A plurality of wear members are positioned to be supported by the body of elastomeric material and to receive the load placed on the bearing. The elastomeric body allows the wear inserts to adjust individually to the load placed on the wear members, which greatly increases the life of the bearing. The wear members are made of a self-lubricating type material, such as one of the fluorocarbons or polyphenylene sulfide resin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A bearing comprising a housing including an annular member and a flange member extending from the annular member transverse the longitudinal axis of the annular member, an annular body of elastomeric material supported by the housing and a plurality of inserts embedded in the body of elastomeric material with each insert having one side exposed to combine with the other inserts to provide a bearing surface and its other side positioned near the flange member to transmit the load on the bearing surfaces of the inserts to the flange member and to allow each insert to adjust individually to the load imposed on the bearing.
Claim 2
Dependent Claim
105 words
A bearing comprising a housing including an annular member and a flange member extending from the annular member transverse the longitudinal axis of the annular member, an annular body of elastomeric material supported by the housing and a plurality of inserts embedded in the body of elastomeric material with each insert having one side exposed to combine with the other inserts to provide a bearing surface and its other side positioned near the flange member to transmit the load on the bearing surfaces of the inserts to the flange member and to allow each insert to adjust individually to the load imposed on the bearing.
Claim 3
Dependent Claim
34 words
The bearing of claim 1 in which the wear inserts are located on one side of the flange member to provide bearing support for a load acting along the longitudinal axis of the housing.
Claim 4
Dependent Claim
27 words
The bearing of claim 1 in which the wear inserts are positioned to provide bearing support for a load acting transverse the longitudinal axis of the housing.
Claim 5
Dependent Claim
15 words
The bearing of claim 1 in which the wear members are made of self-lubricating material.
Claim 6
Dependent Claim
16 words
The bearing of claim 4 in which the wear members are made of polyphenylene sulfide resin.
Claim 7
Dependent Claim
17 words
The bearing of claim 4 in which the wear members are made of one of the fluorocarbons.
Claim 8
Dependent Claim
28 words
The bearing of claim 1 in which the body of elastomeric material is provided with a plurality of grooves through which fluid may flow to lubricate the bearing.
Claim 9
Dependent Claim
48 words
The bearing of claim 1 in which the wear members are cylindrical and the support body is provided with cylindrical cavities to receive the inserts having a diameter less than the inserts to cause the elastomeric material of the body to grip the inserts located in the cavities.
Claim 10
Dependent Claim
165 words
A thrust bearing assembly for transmitting the axial load on the output shaft of a downhole motor between the shaft and the motor comprising a housing connected to the motor through which the output shaft extends, a plurality of bearings located in the housing, each bearing comprising a bearing casing having a cylindrical portion and an inwardly extending support member attached to the cylindrical portion between the ends thereof, a body of elastomeric material located on opposite sides of the support member, and a plurality of wear members positioned in the body of elastomeric material on both sides of the support member to transmit the load imposed on the bearing to the support member, said wear members being supported by the body of elastomeric material so that each wear member may adjust individually to the load on each member, means for transmitting the axial load on the output shaft to the bearings, and means for transmitting the load on the bearings to the bearing housing.
Claim 11
Dependent Claim
165 words
