ABSTRACT:
A motor driven household mixer has a housing around a rotary motor in a plastic frame, the motor having front and rear bronze bearing assemblies with a fan adjacent the rear assembly and a beater gear box adjacent the front assembly. This is provided with an improved integral bearing strap and cooler for the front assembly comprising vents in the housing adjacent the gear box and a generally H-shaped one piece bearing strap with means securing one leg of the H to the frame forming the leg around the bearing, with the other and wider leg being bent out of the plane of the H and opening towards the vents said leg extending across the entire bearing width whereby air moved by the fan is funneled by the bent leg toward the entire bearing cooling it. The invention also includes a single means securing the one leg to the gear box in which openings are provided to direct the air to the bearing and around it and below the securing leg to cool the entire bearing and leg by forced convection.
