    Abstract: A bearing assembly 10 for rotatably supporting a shaft member 12. The bearing assembly 10 has an inner ring 16 having an inner surface 34 sized to receive the shaft member 12 therein. A first fastener 28 threadedly engages a first fastener aperture 30 formed in the inner ring 16 such that a distal end of the first fastener 28 engages the shaft member 12 to selectively retain the inner ring 16 to the shaft member 12 for rotation therewith. A first groove 40 extends along the inner surface 34 of the inner ring 16 and is aligned with the first fastener aperture 30 formed in the inner ring 16. The first groove 40 is sized to permit clearance between a burr or other obstruction formed on an exterior surface of the shaft member 12.

    Abstract: Eine Statorbaugruppe beinhaltet einen ringförmigen Körper, der sich um eine Mittelachse erstreckt, und einen ersten Statorzahn, der sich radial von dem ringförmigen Körper erstreckt. Der erste Statorzahn beinhaltet eine erste Spitze, die radial von dem ringförmigen Körper beabstandet ist. Die Statorbaugruppe beinhaltet ebenfalls einen zweiten Statorzahn, der sich radial von dem ringförmigen Körper erstreckt und in Umfangsrichtung von dem ersten Statorzahn beabstandet ist. Der zweite Statorzahn beinhaltet eine zweite Spitze, die radial von dem ringförmigen Körper beabstandet ist. Die Statorbaugruppe beinhaltet ferner ein Versteifungselement, das zwischen dem ersten Statorzahn und dem zweiten Statorzahn positioniert ist. Das Versteifungselement ist dazu ausgelegt, einer Verformung der Statorbaugruppe zu widerstehen.

    Abstract: A motor controller for a blower in a gas-burning appliance. The motor controller includes a processor configured to receive a measured pressure differential measured by a sensor disposed in an airflow generated by the blower. The processor is configured to compute a motor speed based on the measured pressure differential and a pressure differential set-point for the gas-burning appliance. The processor is configured to operate the blower at the motor speed to drive the measured pressure differential toward the pressure differential set-point.

    Abstract: A bearing lubricator for lubricating a lubricated bearing is provided. The bearing lubricator includes a reservoir configured to contain lubricant, a bearing lubricator for lubricating a lubricated bearing, a conduit connected to the reservoir and to the bearing; and mechanism and a controller. The mechanism is operably connected to at least one of reservoir and the conduit. The mechanism is adapted to advance the lubricant from the reservoir to the conduit when actuated. The controller stores a triggering value of a parameter. The controller is further adapted to actuate the mechanism when a signal indicative of the triggering value is advanced to the controller. The bearing lubricator also includes a sensor operably connected to the controller. The sensor is adapted to measure a parameter of a measured bearing and to send a signal to the controller indicative of the value of the parameter.

    Abstract: A blower assembly includes a housing including an outlet and a cutoff point positioned proximate the outlet. The blower assembly also includes an impeller including a plurality of blades that each includes a tip portion including a radially outer edge and a transition point that divides the radially outer edge into a first portion and a second portion. The impeller is positioned within the housing such that a first radial gap is defined between the cutoff point and the first portion and a second radial gap is defined between the cutoff point and the second portion. The first radial gap includes a constant width that is shorter than a width of the second radial gap.
