System and method for providing drive shaft braking for irrigation machines

Abstract

The present invention provides a system and method for providing drive shaft braking for an irrigation machine. According to an exemplary preferred embodiment, the present invention includes a system for providing drive shaft braking during the operation of an irrigation machine where the irrigation machine includes a drive system having a drive motor and a drive shaft. According to a preferred embodiment, the system in accordance with the present invention preferably includes a cam attached to the drive shaft, an extension arm having a first securing point, a securing arm having a second securing point and a spring attached between the first securing point and the second securing point. According to a further preferred embodiment, the system of the present invention preferably further includes a follower mechanism secured to the extension arm, which applies continual frictional pressure to the drive shaft in response to the force applied by the spring to the follower through the extension arm. According to a further preferred embodiment, an exemplary system according to the present invention functions to hold the drive shaft in place when rotational force is not actively applied to the drive shaft by the drive motor.
