摘要:
A planetary gear system and a pin for coupling a planet gear to a carrier in a planetary gear system are disclosed. The planetary gear system includes a planet gear defining a central planet axis, a carrier disposed adjacent the at least one planet gear, and a pin extending from the carrier through the planet gear generally along the central planet axis. The pin includes a first end, a second end, and an outer surface extending therebetween. The pin further defines an opening extending from the outer surface generally along the central planet axis and at least partially through the pin.
摘要:
A carrier for use in a planetary gear system. The carrier has a plurality of openings or slots offset from a midline thereof. The carrier includes alignment mechanisms positioned in each of the plurality of openings or slots to substantially align each planet gear about the midline of the carrier. The carrier may be used in a planetary gear system for use in a wind turbine. One aspect incorporates eccentric rings in the openings. Another aspect incorporates inserts in the slots. Each of the rings and inserts has openings that, when properly positioned, will substantially bisect the carrier midline.

A temperature measurement device includes a first thermocouple mounted on a tubular body that is shielded from the effects of radiation by a radiation shield, and a second, unshielded thermocouple. A difference in the measured temperatures from the first and second thermocouples is compared with calculated temperatures using an iterative process to determine a corrected temperature of the gas stream that estimates and compensates for incident radiation.

A planet pin, a planetary gear system, and a method for balancing a load on a planetary gear system between respective planet gears. The planet pin includes a planet pin body having a flexure portion between a pair of ends. The flexure portion may be a planet pin body having grooves on opposing sides. The flexure portion may be a pair of pin bodies interference fit into annuluses of a centrally located barrel. The flexure portion may be a pair of pin arms extending from a centrally located ball joint.

A method of assembling a radiant cooler is provided. The method includes providing a vessel shell that includes a gas flow passage defined therein that extends generally axially through the vessel shell, coupling a plurality of cooling tubes and a plurality of downcomers together to form a tube cage wherein at least one of the plurality of cooling tubes is positioned circumferentially between a pair of circumferentially-adjacent spaced-apart downcomers, and orienting the tube cage within the vessel shell such that the tube cage is in flow communication with the flow passage.
