Title:
VIBRATION REDUCING GEAR
Document Type and Number:
WIPO Patent Application WO/2016/171499
Kind Code:
A1
Abstract:
A disclosed vibration reducing gear, according to the present invention, comprises: a gear part (110) that has a gear tooth portion (118) formed on the outer circumferential surface thereof, a circular through-hole (116) formed in the center thereof, and a plurality of first receiving recesses (114) formed in the inner circumferential surface of the through-hole, wherein the gear tooth portion has the same form of gear teeth that are repeatedly formed along the outer circumference of the gear part, and the first receiving recesses are formed with a constant interval therebetween in the circumferential direction with respect to the center of the through-hole, each of which is open at one side thereof; a shaft coupling part (120) installed in the through-hole (116) so as to be spaced apart from the gear part by a specified distance and having a coupling hole (126) formed in the center thereof and a plurality of second receiving recesses (124) formed in the outer circumferential surface thereof, wherein the rotating shaft (12) of a motor (10) is inserted into the coupling hole, and the second receiving recesses are formed with a constant interval therebetween in the circumferential direction with respect to the center of the shaft coupling part, each of which is open at one side thereof, so as to correspond to the first receiving recesses (114); damping members (130) inserted into the first recesses (114) of the gear part and the second receiving recesses (124) of the shaft coupling part; and support plates (140, 150) that support the damping members to prevent the damping members from being separated from the gear part and the shaft coupling part. According to the present invention, the gear part (110) and the shaft coupling part (120) are connected to each other through the damping members (130) so that the damping members (130) absorb the vibration and noise that are generated by the gear tooth portion of the gear part or the rotating shaft of the motor.
