摘要： Provided is a planetary gear reducer including: a sun gear fixed concentrically to a power input shaft; a plurality of planet gears meshing with the sun gear; a ring gear meshing with the planet gears; a planet carrier configured to support a plurality of planet shafts, each of which is a rotational axis of a corresponding one of the planet gear, and to output revolution of the plurality of planet gears as first power; and a cylindrical support connected to the ring gear, non-rotatable relative to the ring gear, and configured to output rotation of the ring gear as second power. The cylindrical support includes, at one part along the direction of a central axis, a flexible structure which is curved radially inward and has a V-shaped longitudinal section. This configuration improves rigidity and prevents misalignment without increasing the weight of the gear reducer.

摘要： A work machine equipped with an automatic hammering function is capable of preventing breakage of the hammer caused by blank firing. Hydraulic oil fed to a hydraulic breaker at the distal end of a work machine is controlled by first and second spools. Operating an operation lever so as to contract single rod type boom cylinders to press the hydraulic breaker against an object to be crushed. Head-side pressure and rod-side pressure of the boom cylinders are respectively detected by pressure sensors. Any one of switches is used to switch the mode of automatic hammering operation between an automatic hammering inhibiting mode and an automatic hammering authorizing mode. In the automatic hammering authorizing mode, a controller controls the first and second spools of the hydraulic breaker so as to open them only when head-side pressure and rod-side pressure of the boom cylinders are in a given range of pressing force.

A negative control pressure control device controls the negative control pressure to an arbitrary value is also provided. The pump characteristic of the hydraulic pump is set such that the discharge flow rate is minimized when the negative control pressure in the negative control circuit is equal to or greater than a first predetermined pressure. Furthermore, an idling detection device that detects whether the hydraulic actuator is in a non-operated state or not is provided. The negative control pressure is forcefully controlled to the first predetermined pressure or higher when the non-operating state is detected.
