Gear assembly having noise-reduction structure and power take-off unit therewith

A meshing gear assembly includes a toothed disk that is supported on a first gear so as to be frictionally engaged therewith, but rotationally and radially movable relative thereto. The circumferential width of each tooth formed on the toothed disk is preferably larger than the circumferential width of each tooth formed on the first gear, and the outer diameter of the toothed disk can be larger than the outer diameter of the first gear. The first gear and the toothed disk mesh with a second gear such that as the second gear rotates, the toothed disk and the first gear also rotate. However, the toothed disk and the first gear rotate at different speeds because the difference in the number of teeth formed thereon. Because the teeth formed on the toothed disk have a larger circumferential thickness and a larger outer diameter than the teeth formed on the first gear, a tight meshing engagement with the second gear is provided. This tight meshing engagement, in combination with the frictional engagement of the toothed disk with the first gear, takes up backlash between the first gear and the second gear.

Method for replacing a tacking fastener

A temporary fastener that fastens two adjacent workpieces. The fastener includes a shank that extends through a hole of the workpieces. Extending from one end of the shank is a conical shaped head. The fastener also contains a pull stem which has a head located adjacent to the blind end of the shank. The stem head is pulled through the shank to expand and tightly fasten the shank to the workpieces. The fastener is removed by drilling through the head and the shank. The diameter of the conical shank head is smaller than the diameter of the drill so that part of the head does not become attached to the drill bit and scratch the workpiece. The conical shape of the head also reduces the volume of fastener material to further reduce the size and amount of chips produced during the drilling process. The tightly engaged shank prevents the fastener from rotating during the drilling operation.A method of replacing a tacking fastener that temporarily joins two adjacent workpieces with a permanent fastener to permanently join the workpieces. A drill bit is engaged with an inner channel of the temporary fastener at a head of the fastener. The drill bit has a diameter larger than the head diameter. The head, the shank, the first workpiece, and the second workpiece are drilled through to form a hole through the workpieces. The first workpiece and the second workpiece are joined with a permanent fastener through the hole.

InactiveUS20060051204A1Facilitates maximum air flow efficiencyReduce airflow noisePump componentsStatorsEngineeringInducer
A draft inducer blower housing for high efficiency furnaces, including a housing body and housing cover which define an exhaust transition therebetween, which transitions the air flow from the circular main cavity of the blower housing to the blower housing outlet. A cutoff portion of the blower housing is formed as an insert member or third housing component, which is located within a recess defined within the housing body proximate the outlet. The cutoff insert member may be attached to the housing body and captured between the housing body and housing cover, and includes a broadly radiused cutoff portion defining the exhaust cutoff of the blower housing. The housing body includes reduced-height mounting lugs, and indentations provided in the outer wall of the housing body above each mounting lug. The reduced height mounting lugs reduce the amount of material needed to form the housing body, and allow the use of shorter fasteners to secure the blower housing to the wall of a furnace. The indentations in the outer wall of the blower housing facilitate easier access to the openings of the mounting lugs during installation of the fasteners.
