POWER TOOL
Document Type and Number:
Japanese Patent JP3683480
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power tool having a built-in planet gear device capable of changing speed to a high speed range without rotating an internal gear to eliminate an increase in inertia and generation of vibration and noise caused by arranging a built-in type speed change gear which increases spindle speed by lowering a speed reduction ratio by rotating an internal gear integral with a carrier in a conventional manner in a motor driven drill having a built-in type planet gear type speed reduction gear for reduction the revolution of a motor for example.
SOLUTION: The motor driven tool 1 has a built in type planet gear device 10 of the following specifications. A high speed constitution is provided such that a speed change member 60 is interposed between a first stage planet gear train 20 and a second stage planet gear train 40, and with this speed change member 60 displaced axially, the second stage speed reduction by means of the second stage planet gear train 40 is omitted by connecting a first stage carrier 24 and a second stage carrier 77 directly. This constitution can change speed without rotating the internal gear 73.
