SANDEX is a generic name for our cam units that combine a simple and ideal indexing mechanism, the "Roller gear cam mechanism". Sankyo's original cam technology, consisting of a roller gear cam and a follower spider (turret) is used to complete the units. Sankyo's pick and place units accommodate motion in two directions, as is necessary in workpiece handling, using two reliable solid cam mechanisms. All of these mechanical movements are made accurately at high speed. The "Oscillating Handler" combines oscillation or intermittent indexing and lifting motions, and the "Parts Handler" combines two direction straight movements, such as forward and back.

Lifting gears and conveyor drives in which the drum and driving motor are arranged in parallel require a step-down gear unit with a corresponding large axle base. The lifting gear units in the POSIRED N series are designed for this application and ideally bridge the given distance between the motor and drum. The development of this series is based on widespread experience in crane engineering, belt conveyor drives, winches, and hoisting devices. The accessories needed for this application such as elastic clutches, barrel clut-ches, brakes and substructures, can be supplied together with the gear reducers.
Technical Data:
Torque (T2 nominal): 8,000 up to 800,000 Nm
Transmission Ratio: 12.5 up to 500 iN

GEAR SERIES - GB2
SPUR REDUCTION GEARHEAD.
Design - In GB2 gearhead, spur gears rotate on hardened steel spindles which are polished to a mirror finish. In order to damp running noise at slow running times and low motor loads, the initial spur gears after the rotor shaft are made of injection moulded poly acetal. The spur gears close to the output shaft on the other hand, are made of metal. The output shaft is mounted in two special brass bushes. The entire gear train is put between metal plates with a plastic frame. It is permanently lubricated and therefore requires no maintenance. Thicker shaft (Ø 6-7mm) mounted in robust bushings (Ø 12) are available in a new variant (GB2S). Single-way or two way slipping clutches can
also be installed to enable the output shaft to be rotated while the motor is stationary. GB2 can also be combined with small DC Motors. To achieve higher gear torque, GB2 can be mounted on GB4. Linear drives also possible with small sized motors (Ø<36mm).

Varvel continues to score successes in its product range completion with the new hollow output shaft speed reducers 'Series RN-RO-RV'.
Each size of this new series - displayed at the former Hannover Fair, April 2007 - is designed with a common base body that gives rise to three different speed reducer lines by the means of the appropriate input module fitting: RN shaft mount, RO horizontal and RV vertical input bevel/helical.
Speed reducers are designed in six sizes - aluminium pressure die cast for the smallest three and grey cast iron for the bigger ones - with 30 reduction ratios in two and three stages, and output torques from 180 Nm to 3200 Nm.
Multiple foot-, flange- or torque arm mountings are available as well as hollow output shafts (keyed, shrink-disk, splined) and solid simple or double sided.
Same fixing footprint for the three versions, high flexibility, easy mounting and quick lead times are the pluses that make the speed reducers RN-RO-RV a really new and advanced range.
