2 As the world's attention shifts toward global environmental issues, companies are placing strong emphasis on internationally recognized guidelines such as ISO The trend is to raise productivity and efficiency without compromising conservation efforts. Sankyo looks at this as an opportunity to build environment-friendly products with sound, perfected, and reliable motion characteristics. Introducing the Sandex (Alpha) series, a new addition to our Sandex series, which has provided the industry with quality indexing equipment for 25 years. The Sandex series is a low profile indexing drive featuring a cost-effective geared motor. Notice these easy-to-integrate and ease-of-use features: Frequency inverter comes standard. No more clutch/brake components or other wearable parts Rigid output surface for directly mounting dials. Ecology and economy -- two words synonymous with today's industrial sector. Two qualities you get when you integrate the Sandex series into today's highly productive automation machines. The series is an all-in-one indexing drive complete with geared motor mounted directly on the input shaft. The indexing motion comes from the same roller gear cam mechanism found in all of our Sandex products. As a result, you get ease of use and maintenance with all the qualities of a Sandex. The series comes with a frequency inverter allowing controlled starts andstops without a clutch/brake mechanism. By eliminating mechanical elements, we succeeded in reducing costs and maintenance. Center distances available in eight standard sizes: 70, 90, 110, 150, 190, 230, 330, and 450mm. Wide selection of stops: 2 to 32 Rigid large flange surface Low profile housing Standard hollow fixed shaft inside output flange Can be mounted with up to 3 pairs of timing cams and sensors Optional Torque Limiters for ouptut shaft Standard hollow-center shaft-type geared motor with inverter controller.

5 Sandex model codes are specified by a combination of numbers and alphabetic characters. An erroneously specified product code will usually result in a product unusable in other applications. Use the same caution when specifying the product code for the geared motor and optional torque limiters. When specifying other requirements such as special gear ratios, motor voltages, copper plated terminal boxes, etc., include the symbol X at the end of the product code and attach a separate user requirements sheet. Queries concerning price, volume, and delivery should be directed to a Sankyo salesman or representative.

38 When sizing a Sandex Alpha Series, make sure to follow these guidelines to ensure best performance and to prevent premature breakage. The conditions for driving the input and the loads on the output shaft are also important factors. Make sure you know these conditions before sizing your indexer. Feel free to consult with your Sankyo representative as these calculations involve unique index-related formulas and symbols. Sankyo can also size an indexer for you by performing the necessary torque calculations. Use the FAX Sheet at the end of this brochure for prompt service. Select the number of stops from the Standard Specifications that best suits the usage conditions. Number of stations Stopping time (t1) and Indexing time: (t2) Mass of table/dial: outer diameter Quantity, mass, and mounting pitch of tools or fixtures Quantity, mass, and mounting pitch of workpieces Options (TorqueLimiter, variable frequency drive) Expected service life

42 An indexer that uses a roller gear cam mechanism is precision equipment. Improper handling can lead to premature breakage, and it can damage the automated machinery in which it is integrated. Make sure you fully understand this aspect the product and handle it properly. Use an oil stone to hone the mounting surface free from nicks, burr, and residual paint. Clean the surface and apply grease or mineral oil to prevent rust. Then, install the indexer. The indexer is subject to sharp fluctuating loads so make sure it is mounted securely. The ambient operating conditions may have a significant impact on the performance of this indexer. Review the conditions where the indexer will be installed beforehand, and take all necessary preventive measures. a) The ambient operating temperature for a standard indexer is from 0 C to C. b) An indexer that is used in a moist atmosphere is prone to rusting. Rust proof thoroughly. c) The input and output shaft is sealed with an oil seal. Depending on the amount and type of dust, this seal can wear and eventually leak. Consider a furnishing a protective cover. d) Electrical current can cause the indexer to wear. Make sure electrical circuits are properly insulated. Automated machines built around an indexer usually has many parts that are intricately assembled. Often, the machine will not run after it is first assembled. After assembling the major components, you should always operate the machine by hand, or micro-jog if available, to make sure the parts move without interference. Motor sizes from 0.4 to 1.5 kw have a hex-wrench hole, where the fan is mounted, to allow hand-operated testing. (This hole is square for 1.5-kW motors.) Always test run by hand, or micro-jog if available, to make sure the operation is smooth. Then, run with power and check for noise, vibration, temperature changes, oil leaks, and other possible signs of failure. When center line of the keyway in the input shaft points toward the turret, the input shaft is at the indexing angle reference position. On an indexer, the starting position of the indexing angle and the key should be used for positioning and for the safe transmission of shock loads. During normal operation, the key should not be relied upon. Instead, use a different means of transmission. a) The output of an indexer is subject to positive and negative inertia torque as it indexes and stops, thus requiring sufficient stiffness to ensure positioning accuracy. There is no tolerance for vibration. The output on the AD Type models is designed with a wide flange surface to allow precision mounting of tables or dials. b) To ensure precise positioning of the workstations on the table, bore an oversized center hole by 0.1 to 0.2 mm. Center the table by moving it radially and the direction of rotation, then tighten the bolts and, if necessary, insert a knock pin. The recommended tightening torques for bolts in the indexer flange are given below. c) The center of the output is standard equipped with a robust fixed flange with a thru-hole. You can directly mount your fixed table to this flange. You can machine a hole in your mounting base where the center of the output will be. This provides a convenient passage for piping and wiring. Lubrication serves an important role. It reduces friction of rolling parts, removes frictional heat, and prevents rust, in addition to other benefits. Use of improperly selected oil will reduce the accuracy and life. Make sure to select an oil that suits the operating conditions. Sankyo recommends the use of a good quality mineral oil with pressure additives. Do not mix with oil from different manufacturers. The viscosity depends on the operating speed. Use the table below to select the proper oil. a) Backlash in the input and output will increase over time. Always perform regular inspections and adjustments. b) If the indexer is over filled with oil, the indexer will show abnormal temperature rises and may even leak. Make sure the indexer has the proper amount of oil at all times. c) Replace the lubrication oil every 3,000 hours. Or, if the indexer is not operated that long, replace it at least once every one to two years.
