Gearboxes and couplings for the Big Apple

Renold Hi-Tec Couplings product story
Edited by the Engineeringtalk editorial team
Aug 15, 2008
Major subway car builders like Kawasaki, Alstom and Bombardier have all used Renold couplings in their propulsion systems with proven success.
Renold has won a US $14 million contract to supply rail traction gearboxes and couplings to Alstom for trains ordered by the New York City Transit Authority (NYCT).
The contract is phase two of a three phase schedule and is expected to be fulfilled over an 18 month period commencing May 2008.
The couplings are being fitted on the new R160 series trains destined for operation on the famous New York Subway.
The subway system carried over 1.5 billion passengers in 2007 and the R160 cars will run on the highest traffic areas of the system, so reliability is an essential factor in design and manufacture.
The new gearboxes and couplings are fitted in-between the AC traction motor and the drive axle.
They allow the safe transmission of torque while the motor and gearbox shafts are misaligned, vertically and horizontally, by up to 4.5 degrees.
Renold has a long supply history with NYCT and many other US transit authorities dating back over 45 years.
Renold's couplings are extremely robust in design, have an excellent service history, and the major subway car builders like Kawasaki, Alstom and Bombardier have all used Renold couplings in their propulsion systems with proven success.
