Abstract

PURPOSE:To easily confirm the wear of a brake shoe, by placing brushes in positions corresponding to the wear limit of the shoe and by closing an electric circuit through the brushes and a rotary part of a rotary electric machine when the shoe is worn out. CONSTITUTION:Brush carriers 1e are mounted with insulating plates 1f on both the sides of a brake shoe carrier 1c so that the sliding faces of brushes 1d are located on the same plane as the use limit 1b a brake shoe 1a. Electric wires 1g are connected to lead wires for the brushes 1d and to a power source and an alarm of display circuit. When a brake 1 is in operation and the brake shoe 1a is in contact with a rotary part 2 of a rotary electric machine and the shoe is worn to the use limit, an electric circuit 1h is closed through one brush 1d, the rotary part 2 and the other brush 1d. Therefore, it can be easily confirmed from the alarm or display circuit that the brake shoe is worn to the use limit.
