Contact wheel drive

An energy recovery system for an air handling unit comprising

• an energy recovery wheel configured to rotate about a first axis,
• a motor, and
• a drive wheel coupled to the motor for rotation about a second axis that is offset from the first axis and the energy recovery wheel and having an outer surface engaged directly with an outer surface of the energy recovery wheel;
• an actuator mount configured to support the motor relative to the energy recovery wheel, the actuator mount comprising a motor mount coupled to the motor and a stationary mount configured to be coupled to the air handling unit in a fixed position and configured to support the motor mount for pivotable movement about an actuator pivot axis so that the drive wheel is pivotable into contact with the outer surface of the energy recovery wheel;
• wherein the motor mount comprises a mount plate supporting the motor, a pair of mount flanges coupled to the mount plate, and a mount rod coupled to the mount flanges and providing the actuator pivot axis.

An energy recovery system for an air handling unit, the energy recovery system comprising a support frame including a plurality of side frame members at least partially defining an air-supply section and an air-return section and a seal member arranged between the air-supply section and the air-return section, an energy recovery wheel positioned within the air-supply section and the air-return section and configured to rotate about a rotation axis that is between the air-supply section and the air-return section, the energy recovery wheel including an outer shell extending circumferentially around the rotation axis and an energy absorption media between the outer shell and the rotation axis, and a wheel actuator configured to drive the energy recovery wheel to rotate about the rotation axis, wherein the seal member interfaces with a radially-outer surface of the outer shell and extends generally parallel with the rotation axis from a forward end of the outer shell to a rear end of the outer shell and is formed without any slots opening toward the outer shell between the forward end and the rear ends an actuator mount configured to position and retain the wheel actuator relative to the energy recovery wheel, the actuator mount including a stationary mount coupled in a fixed position relative to the energy recovery wheel, a motor mount coupled to the stationary mount for pivotable movement about an actuator pivot axis and configured to support the wheel actuator relative to the energy recovery wheel, and a tensioning system configured to bias the motor mount to pivot about the actuator pivot axis so that the wheel actuator is biased into contact with the energy recovery wheel;

• wherein the motor mount includes a mount plate configured to support a motor of the wheel actuator, a pair of mount flanges coupled to the mount plate, and a mount rod coupled to the mount flanges and providing the actuator pivot axis.
