Generally, a gear reducer or a reduction gear is a device for increasing the torque by reducing the number of revolutions (rpm) of the motor by configuring gears having different gear ratios.

A speed reducer is also used for lifting or lowering a heavy heavy object. A brake is provided for the speed reducer, or a worm reducer having the same function or a reverse rotation is used.

For example, in a hoist, a lever block, a chain block or the like, a brake device is formed on the side of the gear box, and a worm reducer which can not be reversed mainly is used for the elevator and the escalator.

Here, the input planetary gears are provided with a plurality of the input planetary gears so as to be maintained at predetermined intervals.

In addition, the power relay section is provided with a ring gear having an output side internal gear disposed on the outside of the input planetary gear of the power input section and formed on one side of the power transmission section, and an output side internal gear on the other side, .

Here, the ring gear is provided with a support plate between the output-side internal gear and the input-side internal gear, and the support plate is provided with a through hole through which the main shaft penetrates.
