Reg Technologies Inc. and REGI U.S., Inc. Complete Fabrication of RadMax Drive Shaft

Reg Technologies Inc. and REGI U.S., Inc., companies focused on development of axial vane type rotary engines, announced in a press release recently that they have completed the fabrication of the RadMax drive shaft for the demonstration model.

According to sources, the RadMax engine is a patented internal-combustion engine that is built around a rotary design. Reg Technologies, Inc. owns the worldwide rights to the RadMax rotary technology and REGI U.S., Inc. owns the U.S. rights to the RadMax rotary technology. Reg Technologies’ primary goal is to license the RadMax technology and/or to participate in joint ventures to manufacture specific RadMax applications.

Specifically, the Rand Cam/RadMax rotary technology is an improved axial vane type rotary engine used in the revolutionary design of lightweight and high efficiency engines, compressors and pumps. The RadMax engine has two unique moving parts, the vanes (up to 12) and the rotor, compared to the 40 moving parts in a simple four-cylinder piston engine.

According to Reg Technologies Inc. and REGI U.S., Inc., the RadMax has an innovative design that makes it possible to produce up to 24 continuous power impulses per one rotation that is vibration-free and extremely quiet. It generally would have two to three times the power and weigh half as much as a Wankel engine of the same size.

Featuring multi-fuel capabilities, the RadMax engine can operate on fuels such as gasoline, natural gas, hydrogen, propane and diesel. Some the advantages delivered by RadMax, apart from multifuel capability, include: fewer moving parts, high and efficient rates of combustion, low weight, reduced vibration, and ease of maintenance.

The RadMax engine has a variety of possible applications, ranging from the tiny weed-trimmer to the commercial and/or military jet engine. It also has a wide spectrum of uses, from air conditioner compressors to air and steam expanders to hybrid vehicle applications, to personal power generation.

The drive shaft of RadMax engine, which was recently fabricated, works in conjunction with the rotary union. It features include mounting provisions for the Rotary Union, Shaft Lock Nut that preloads the Rotor, main bearings, and tight pilots for securing the rotor in position. It includes key slots for securing the load to RadMax as well.

Upon completion of the fabrication of the RadMax drive shaft for the demonstration model, Robert Grisar, VP of Engineering for REGI U.S., Inc. said in a statement, "The drive shaft is similar to a crank shaft in a reciprocating engine as it delivers rotational power to the transmission, however, the center is hollow and provides a path for oil to cool rotating components."

According to a press release, detailed thermodynamic analysis of the RadMax engine was performed last year in conjunction with Belcan Engineering Services of Phoenix, AZ. A design decision was finalized to create a hollow drive shaft to provide a means to lubricate internal rotating components.

Officials with REGI said in a press release that without this device, the internal engine heat would make adoption of aluminum components impossible. By reducing heat, and weight, fuel economy can be enhanced in every RadMax application.

Recently, both the companies had announced the completion of fabrication of RadMax Cam Surface.
