A driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.

A tilt device includes: a drive motor that provides a drive force for swinging a tilt member; an auxiliary cylinder coupled to the tilt member to assist swing of the tilt member by the drive motor; and a control device that performs drive control of the drive motor and the auxiliary cylinder. In the movable range of the tilt member, a moment about the swing axis generated in the tilt member by the gravitational force is always directed to only one side in the rotational direction, and an assistive moment about the swing axis provided to the tilt member by a cylinder pressure is always directed to only the other side in the rotational direction. The control device fluctuates the cylinder pressure such that the assistive moment is less than the moment generated in the tilt member by the gravitational force.

An indexing device includes a drive transmission mechanism, a fixing mechanism. The drive transmission mechanism includes an intermediate gear which includes an intermediate shaft being inserted at an end portion into an accommodation hole formed in a frame, and the intermediate shaft includes an accommodating concave portion and a plurality of through-holes. The fixing mechanism includes a cylindrical pressing member, steel balls and a screw member. There is a gap between the pressing member and a bottom surface of the pressing member in a state in which the pressing member is accommodated in the accommodating concave portion and the steel ball accommodated in each through-hole is in contact with a tapered surface and an inner peripheral surface of the accommodation hole.

A drilling detection system may include a drilling detection circuitry including one or more detection processors configured to receive a vibration signal indicative of vibration associated with a drilling machine configured to drill holes into a substrate and receive a movement signal indicative of movement of the drilling machine relative to one or more positions on the substrate. The one or more detection processors may also be configured to determine vibration associated with the drilling machine, and determine movement associated with the drilling machine. The one or more detection processors may also be configured to determine, based at least in part on the vibration associated with the drilling machine and the movement associated with the drilling machine, the drilling machine has drilled holes into the substrate and a position on the substrate at which the drilling machine has drilled the holes into the substrate.

The cleaning device includes a base, an indexed table, a driving mechanism and a power transmission mechanism. The driving mechanism includes a driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear.

A double rotation indexing device includes two sets of rotation indexing units. Each of the rotation indexing units includes a main shaft and a drive transmission mechanism which includes a drive shaft, a disk-shaped driven member and a drive member. The drive shaft is supported on one end side via a bearing holder and is supported on an other end side via a radial bearing. The drive shafts of both rotation indexing units are connected by a connecting member. A drive motor is connected to an end portion of the drive shaft. The other end of the drive shaft in one rotation indexing unit is connected to the other end of the drive shaft in the other rotation indexing unit.
