ABSTRACT:
An extensible power shaft assembly used, for example, with a portable tree pruner includes a telescoping axial drive shaft assembly and a telescoping housing coaxially surrounding the drive shaft assembly. Overlapping ends of the telescoping drive shaft components are slidably mounted to one another and supported by an intermediate bearing assembly located at one end of one of the drive shaft sections. Provision is made at the opposite ends of the drive shaft sections for accommodating radial misalignment between interconnected driving and driven components. Provision is also made for preventing whipping of the unsupported sections of the elongated drive shaft sections.
