Range of Power Tools

摘要

A range of power tools each includes motor and transmission housings with an electric motor and a transmission mechanism mounted respectively therein, with the transmission mechanism using the rotary output of the motor to drive a cutting tool. An intermediate housing is sandwiched between the motor and transmission housings. Each of the motor housings is the same in shape, and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range. The transmission housing is positioned differently relative to the motor housing in each power tool to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.

主权项

1. A range of power tool comprising at least two power tools, each power tool comprising:
a motor housing and a transmission housing; an electric motor mounted within the motor housing; a transmission mechanism mounted within the transmission housing which uses the rotary output of the motor to drive a cutting tool; an intermediate housing is sandwiched between the motor housing and the transmission housing, wherein the motor housing of each power tool is the same in shape as the motor housing in every other power tool in the range and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range; and wherein the position of the transmission housing relative to the motor housing in each power tool is different to every other power tool in the range in order to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.
