Document Type and Number:
WIPO Patent Application WO/2017/171079
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the performance of vibration reduction in an internal combustion engine. Provided is a balancer device for an internal combustion engine provided with a drive gear 39 rotating in the same direction as a crank shaft 16, a power transmission mechanism 48 for transmitting the rotational power of the drive gear 39, a driven gear 50 that receives power from the power transmission mechanism 48 and rotates in the direction opposite the crank shaft 16, and a balancer weight 54 provided to the driven gear 50. The power transmission mechanism 48 is provided with: a carrier member 40 for transmitting power with respect to a starter motor 60 of the internal combustion engine through a gear unit 67 provided on the outer periphery; and a bevel gear 45 rotatably supported by the carrier member 40, the bevel gear 45 engaging with the drive gear 39 and the driven gear 50. The carrier member 40 has a protrusion 70. A sensor 71 for detecting the protrusion 70 is provided. The phase of the carrier member 40 is sensed on the basis of the detection by the sensor 71.
