System and method for manufacturing a face seal with controlled load tolerance
A method for manufacturing a face seal may generally include positioning a machining device relative to the face seal such that the face seal is compressed between a machining surface of the machining device and a support member on which the face seal is supported. In addition, the method may include removing material from a seal flange of the face seal using the machining device while the face seal remains compressed between the machining device and the support member and monitoring a compressive load applied through the face seal as material is being removed from the seal flange. Moreover, the method may include adjusting the operation of the machining device to prevent further removal of material from the seal flange when the monitored compressive load is equal to a predetermined load setting.
1. A system for manufacturing a face seal, the face sealing including a sealing ring having a seal flange and an inner body portion, the face seal further including an elastomeric load ring positioned around an outer perimeter of the inner body portion of the sealing ring, the system comprising:
a support member configured to support the face seal;
a machining device movable relative to the support member to a machining position at which the face seal is compressed between a machining surface of the machining device and the support member, the machining device being configured to remove material from the seal flange while being maintained at the machining position;
a load sensor configured to monitor a compressive load being applied through the face seal as material is being removed from the seal flange using the machining device,
wherein the operation of the machining device is configured to be adjusted when the monitored compressive load is equal to a predetermined load setting to prevent further removal of material from the seal flange.
2. The system of claim 1 , further comprising a controller communicatively coupled to the machining device and the load sensor, the controller being configured to monitor the compressive load applied through the face seal based on sensor measurements provided by the load sensor, the controller being further configured to automatically adjust the operation of the machining device to prevent further removal of material from the seal flange when the monitored compressive load is equal to the predetermined load setting.
3. The system of claim 1 , wherein the machining surface of the machining device is spaced apart from a support surface of the support member by a predetermined distance when at the machining position.
4. The system claim 3 , wherein the predetermined distance corresponds to a desired axial width for the face seal.
5. The system of claim 1 , wherein the face seal includes at least one anti-rotation feature configured to engage at least one corresponding anti-rotation feature of the support member to prevent rotation of the face seal relative to the support member as material is being removed from the seal flange.
6. The system of claim 1 , wherein the predetermined load setting corresponds to a desired face load for the face seal.
7. The system of claim 1 , wherein the machining device comprises a grinding wheel, the machining surface corresponding to an outer surface of the grinding wheel.
8. The system of claim 1 , wherein the compressive load applied through the face seal is reduced as a thickness of the seal flange is reduced.
