Problems solved by technology

[0010] However, this method has the following disadvantages: that is, when decelerating the number of revolutions of the motor shaft, the greater the reduction ratio, the greater the rotational torque of course.
That is, the torque limiter mechanism cannot be generalized

Abstract

The invention provides a planetary gear type reduction gear with torque limiter that demonstrates always stably torque limiter function, and the invention is characterized in that an input shaft and an output shaft 7 consisting of an output shaft of a DC motor and an output shaft 14 are journalized on a stationary member 11, and at least one stage of the planetary gear type reduction mechanism comprising a central gear 8, a planetary gear 34 meshed with the central gear 8, an inner gear 22 meshed with the planetary gear 34, and a carrier 30 journalizing the planetary gear 34 and a torque limiter are provided between the input shaft and the output shaft.

Description

technical field [0001] The present invention relates to a planetary gear reducer with a torque limiter, and more particularly, to a planetary gear reducer having a torque limiter utilizing the frictional resistance of a friction member in the axial direction of the ring gear. Background technique [0002] A planetary gear reducer is assembled to a shaft of a DC motor, and a reduction mechanism that outputs based on a large reduction ratio has been known. [0003] Since the DC motor is a structure in which the shaft is rotated by applying current to the coil, it has poor performance against a large load from one side of the shaft. That is, if any load is applied to the shaft, if the rotation of the motor shaft continues to be stopped, the current applied to the above-mentioned coil will increase, and the motor will reach a high temperature, causing problems such as burning or melting of insulating materials, short circuits, and poor contact. [0004] In addition, when a redu...
