There is an increasing need for high-precision gear machining to meet customer demand for low-noise and low-vibration planetary gear systems. Mitsubishi Heavy Industries, Ltd. (MHI) has been developing high-precision gear-cutting technologies for use before heat treatment in the production of ring (internal) gears, one of the components of planetary gear systems. However, high-precision high-efficiency gear grinding is also essential after heat treatment to eliminate distortion and improve gear accuracy. In this paper, we report on the development of the Mitsubishi ZI20A grinding machine, the world's first internal gear grinder for use in volume production. Planetary gear systems are widely used in automatic transmissions of vehicles and power transfer systems for hybrid cars because of their compactness and high reduction ratio. There has been an increasing demand for higher precision internal gears as well as for external gears in transmissions to suppress noise and vibration. To meet this demand, gear manufacturers are seeking high-precision high-efficiency techniques for grinding internal gears after heat treatment. Figure 1 shows the manufacturing flow for the volume production of ring (internal) gears. Traditionally, ring gears have often been built into gear systems after heat treatment without being subjected to the finishing process. However, controlling the precision of gears after heat treatment...

The purpose of this map is to assist National, State and local organizations to target their resources and to implement radon-resistant building codes. This map is not intended to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested, regardless of zone designation.
