摘要： A separable rotary tool adapter consists of a low-speed rotary unit (A) having casings (1, 2); a first rotary shaft (3) in the casing connectable to a driving shaft of the machine tool and a second rotary shaft (5) orthogonally drivingly connected to the first shaft; a high-speed rotary unit (B) having a casing (15) detachable to the casing of the low-speed rotary unit (A); a rotary shaft (20) in the casing of the high-speed unit having a free end portion (23) connectable with a rotary tool; and a planetary roller mechanism having two parts engageable with and disengageable from each other in the axial direction, each part being cooperatively associated with one of the high-speed rotary shaft and the second rotary shaft. In the low-speed rotary unit (A), a first part of the planetary roller mechanism is attached to the second rotary shaft (5) engaged with the first rotary shaft (3) at right angles via a transmission mechanism and includes planetary roller driving retainers (9) or shaft pins (10). In the high-speed rotary unit (B), a second part of the planetary roller mechanism is engageable with and disengageable from the first part. The separable rotary tool adapter in which the low-speed rotary unit (A) and high-speed rotary unit (B) are unitarily combined is mounted on a rotary tool mounting portion of a turret in a machine tool, e.g., a turret lathe.

摘要： A traction drive tool adapter, has a rotary portion provided at its front half section with planetary roller-inserting bores extending radially from the outer circumferential surface of the rotary portion into a central bore therein, each of the roller-inserting bores having planetary rollers driving shaft member-setting grooves continuing from two ends of the roller-inserting bore that are opposed to each other in the axial direction of the central bore. Each driving shaft member which supports a relative planetary roller is set in the front half section of the rotary portion by inserting the planetary roller from the side of the outer circumferential surface of the front half section in the radial direction of the rotary portion into the roller-inserting bore, and the end sections of the shaft member into the shaft member-setting grooves, and the outer circumferential section of each planetary roll is engaged with an annular fixed track in a fixed portion of the adapter and the outer circumferential section of a sun roller in a tool mount portion of the adapter. A thread is provided in a through bore extending from the rear end of the rotary portion to the central bore in the axial direction thereof, and a male screw is engaged with the thread. Labyrinth seals are provided at the outer ends of the relative rotary regions between the fixed, rotary and tool must portions, and elastic contact lip-carrying rings are fitted on the inner side of the labyrinth seals.
