The present invention discloses a power transmission apparatus. The power transmission apparatus includes: an input shaft including a male screw portion formed thereon; a pair of input gears formed on the input shaft to be freely rotatable with the male screw portion being interposed therebetween; an output gear formed to be rotatable in a state of being linked with the pair of input gears; and a power interrupting unit screw-coupled to the male screw portion of the input shaft, and configured to rectilinearly reciprocate along the input shaft by a rotation of the input shaft to be selectively engaged with any one of the pair of input gears so as to transmit a power.

A ball screw with a support device includes: a screw; a nut unit movably mounted on the screw; a support device including: a first support seat and a second support seat which are movably mounted on the screw and located at two sides of the nut unit; and a speed control device capable of presetting a speed of the nut unit and the first and second support seats, wherein the speed of the nut unit is V.sub.NT, the speed of the first and second support seats is V.sub.SUP, and they satisfy the relation: 0<V.sub.SUP/V.sub.NT<. When the two ends of the screw are used as a fixing end and a support end, respectively, the ball screw can have an optimized critical rotation speed, which consequently improves the work efficiency of the ball screw.

According to one embodiment, an arm structure includes a base, a first link, a second link, a connecting member, and a gravity compensation mechanism. The first and the second links are rotatable in a vertical direction. One end side of the first link is pivotally attached to the base via a first rotating shaft. One end side of the second link is pivotally attached to another end side of the first link via a second rotating shaft. A length of the first link is same as a length of the second link. The second link rotates around the second rotating shaft. A rotation angle of the second link is twice a rotation angle of the first link. A rotation direction of the second link is opposite to a rotation direction of the first link. The gravity compensation mechanism compensates for torque generated around the first rotating shaft by gravity.

A gear box for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith. A secondary rotational gear is engaged with the primary rotation gear and rotates therewith. A secondary shaft is attached to the secondary rotational gear and rotates therewith. A primary oscillation gear is attached to the gear box primary shaft and rotates therewith. A secondary oscillation gear is rotationally engaged with the primary oscillation gear and rotates on the secondary shaft. An eccentric is coupled to the secondary oscillation gear and rotates in concert therewith. A yoke is engaged with the eccentric and oscillates on an axis perpendicular to the secondary shaft in response to the lobe. The gearbox secondary shaft moves along its axis in concert with yoke oscillation. A housing is pivotally attached to the yoke and pivotally attached to a casing at a casing.

A mechanism 21 for converting rotating motion to rotating and reciprocating motion and/or vice versa. The mechanism has a housing or support 22, a first member 23 rotatable about a first axis and reciprocable along the first axis, and a second member 2 rotatable about a second axis spaced from the first axis. Rotation of the first member 23 or the second member 25 causes rotation of the other member. A guide 29a, 29b is configured to contact a cam surface 27a, 27b. The cam surface or the guide is provided on the first member 23. The cam and guide are configured to cause the first member 23 to rotate upon movement of the first member along the first axis, or to move along the first axis upon rotation of the first member 23.
