Abstract
A fluid containing component is provided having a structure and a sump for storing a fluid. A gear baffle is disposed between the rotatable component and the structure. The gear baffle includes a first side end and a second side defining a gear cavity therebetween. The fluid displaced by rotation of a gear positioned within the gear baffle collects on inner surfaces of the gear baffle and is directed out of the gear baffle through at least one flow port of the baffle.
Claims14
A gear baffle disposed proximate to a gear, the gear at least partially submerged in a fluid, the gear baffle comprising:
- a body having a first side and a second side;
- a gear cavity between the first side and the second side which partially encloses the gear;
- at least one flow port;
- and
- a collector end face having a first side portion extending outwardly with respect to the first side of the body, and a second side portion extending outwardly with respect to the second side of the body, a first channel passage created in the first side portion, and a first channel flow diverter directing a portion of the fluid from a first side channel into the first channel passage, the first channel passage in communication with the first side channel via a first channel entrance;
- wherein a fluid displaced by rotation of the gear positioned within the gear baffle collects on the first side and the second side of the gear baffle and is directed out of the gear baffle through the at least one flow port of the gear baffle.

An assembly comprising:
- a gear baffle disposed between a gear and a structure, the gear baffle including:
- a body having a first side and a second side and a gear cavity between the first side and the second side which partially encloses the gear with the gear at least partially submerged in a fluid;
- multiple flow ports;
- and
- a baffle collector end having a collector end face wherein the collector end face includes a first side portion extending outwardly with respect to the first side of the body, and a second side portion extending outwardly with respect to the second side of the body, a first channel passage created in the first side portion, and a first channel flow diverter directing a portion of the fluid from a first side channel into the first channel passage, the first channel passage in communication with the first side channel via a first channel entrance;
- wherein as the gear rotates, the fluid contacts gear teeth of the gear and is propelled centrifugally outward due to centrifugal force for collection after contacting the inner walls of the baffle collector end;
- and
- wherein the fluid displaced by rotation of the gear positioned within the gear baffle collects on the first side and the second side of the gear baffle and is directed out of the gear baffle end face and through the multiple flow ports of the gear baffle.

A gear baffle system, comprising:
- a structure;
- a sump disposed within the structure for collecting a fluid;
- a gear baffle disposed between a gear and the structure, the gear baffle including:
- a body having a first side and a second side and a gear cavity between the first side and the second side which partially encloses the gear with the gear at least partially submerged in the fluid;
- multiple flow ports including a circumferential flow port,
- a first side port and a second side port;
- a baffle collector end having a collector end face wherein the collector end face includes a first side portion extending outwardly with respect to the first side of the body, and a second side portion extending outwardly with respect to the second side of the body, a first channel passage created in the first side portion, and a first channel flow diverter directing a portion of the fluid from a first side channel into the first channel passage, the first channel passage in communication with the first side channel via a first channel entrance;
- and
- wherein the first side channel includes a side channel inlet wall oriented at an angle with respect to an inner wall of the first side of the body, the angle ranging between approximately 0 to 45 degrees to promote transitioning of fluid flow into the first and second side ports;
- wherein the fluid displaced by rotation of the gear positioned within the gear baffle collects on the first side and the second side of the gear baffle and is directed out of the gear baffle end face and through the multiple flow ports of the gear baffle.
