- Page 7 Unit 2 Handling your Sandex 1. Operating theory SANDEX units operate based on the following principal. A globoidal cam is mounted onto the input shaft. This cam interlocks with the turret portion of the output shaft. The turret has cam followers along its perimeter, which are in contact with the tapered ribs on the cam.
- Page 8 Unit 2 Handling your Sandex 2. Handling your SANDEX Over 90% of the mechanical failures reported with roller gear cam equipment comes from careless or improper handling. Improper handling not only reduces the life of your SANDEX unit, it can also affect the performance of both the SANDEX unit and your machine.
- Page 9 Unit 3 Transportation and environment 3. Transportation and Environment 3.1 Shipping condition (1) All SANDEX products are thoroughly inspected after the final assembly. Only those products that pass this inspection are shipped. (2) Before shipped, each SANDEX unit is filled with lubrication oil in accordance to the customer’s operating speed and environment.
- Page 10 Unit 3 Transportation and environment oil seal may wear and thereby cause oil leaks. This is particularly evident when chemicals are used. Chemicals can also cause and or accelerate rust and corrosion. When using your SANDEX unit in dusty areas, you should consider using protective covers made from stainless steel or plastic.

Reset the 24VDC power to finish the absolute encoder’s setup operation. 5.2 Setting zero position (starting position) The Sankyo Alpha series index drive is equipped with a servomotor as part of our standard package. Manual adjustment for positioning and timing purposes of the indexing drive can easily be accomplished by using the jog feature. -

3) Start: While in auto mode this signal will start the preprogrammed motion that was written by Sankyo America. Each of these units will be programmed in accordance with the customer’s specifications. 4) CW/CCW: This signal will cause the servomotor to execute the preprogrammed motion in a counterclockwise (CCW) direction. -

Handling procedures for the output shaft The output shaft on an indexing drive is subject to momentous torque during starting and stopping. Therefore, the shaft must be torsionally rigid. To maintain positioning accuracy, the output shaft must have minimal run out. The run out on a standard SANDEX is within 0.02 mm (.0008 ).
- Page 25 Unit 7 Lubrication 7. Lubrication Lubrication is an effective and vital means for maintaining the life of your SANDEX unit. Lubrication can minimize wear by reducing friction between rolling members, removing friction heat, and preventing rust on rolling surface. The statistical life of the SANDEX unit is based on rolling fatigue.
- Page 26 The viscosity you choose should also meet the ambient temperature requirements of your SANDEX unit. The following table gives the viscosity for a standard temperature range from 0 to 40 degrees Celsius(32 104°F). Consult Sankyo for usage outside of this range. 7.3 Lubricating oil viscosity’s...
- Page 27 Unit 8 Filling and replacing lubricating oil 8. Filling and replacing lubricating oil Lubrication is a crucial factor for maintaining the operating life of your SANDEX unit. These units feature a high level of precision, and a resistance to friction. However, improper lubrication can reduce the life of the unit.
- Page 28 Unit 9 Lubricating greases 9. Lubrication greases SANDEX units use an oil bath lubricating system. In certain mounting positions, the bearings sit above the oil level. In this case, a sealed lubricating device is installed exclusively for the bearings and grease nipples are attached wherever grease must be reapplied.
