ABSTRACT:
A laundry dryer includes a cylindrical drum shell mounted for rotation on front and rear stationary bulkheads of the dryer. A drive system is configured to rotate the drum in first and second opposite directions. Three rollers are arranged about a lower portion of the drum circumference, on the rear bulkhead, to stably support the rotatable drum during rotation in the first and second directions. The arrangement can also avoid potential flexing and distortion of a cylindrical drum shell of relatively large diameter. In addition, a reversing idler assembly is provided for maintaining proper tension on a drive belt during drum rotation in the two directions. The assembly provides a biased mount for two pulleys on a pair of arms integrally formed with a spring as a single piece, in lieu of separate articulated mounting arms and a separate biasing spring.
