First, the installation
(1) Preparation work
1. When moving the CAMDEX indexer, it is not possible to use the input shaft or the output shaft to lift or support, as this will have a negative impact on the accuracy of the product, or even shorten its service life. Use a lifting eye to move if needed. 2. The body of the CAMDEX divider has oil filling holes, oil mirrors and oil discharge holes. Please pay attention to ensure that these holes can be easily touched for future maintenance and maintenance.

3. The CAMDEX indexer must be mounted on a flat and sturdy foundation. At the same time, this foundation must be able to withstand the vibrations generated by other machine components. This is very important to ensure the performance of the product. 4. Care must be taken during installation to ensure that all connected components must be aligned and locked with the input and output shafts, paying particular attention to the tightness of the keyway and screws. Whenever possible, use tapered connectors or flanges that can be locked with screws.
(2) Remove the oil hole screw
When the CAMDEX indexer is running at high speed or continuously, the lubricating oil inside the box will generate a certain amount of heat. If the box cannot be discharged for a long time, it will have certain influence on the life of the indexer and the oil seal and other parts. Therefore, there is one small wire on the oil hole screw of each indexer. Please remove the small screw after the indexer is installed to achieve the ventilation effect, thus ensuring the service life of the indexer. Please make sure to remove the small oil hole screw before using this product, otherwise it will cause oil leakage inside the product, stop running or even damage internal parts.
Second, the working environment
(a) temperature
  The CAMDEX indexer is suitable for operation in 0 to 40 degrees Celsius. If the product needs to operate at the above temperature standard, please follow the instructions below: 1.-20~0°C: The viscosity of the lubricating oil will increase at a lower temperature than the normal temperature, so the number of revolutions cannot be increased. Use a lubricant that is lower than the recommended viscosity. 2.40~70°C: The viscosity of the lubricating oil will decrease at a higher temperature than at the positive temperature, thus causing a decrease in lubricating performance and accelerating the wear of the inner parts. Therefore, use a lubricant that is higher than the recommended viscosity. 3.70~100C: The standard seal is not suitable for use at this temperature. Need to be replaced with a high temperature seal. If you need this, please contact us.
(2) Humidity
1. Humidity in the air can cause rust on the surface of the product. Therefore, in an environment prone to rust, the mounting reference surface should be coated with butter or rust preventive oil; the machined surface and the input/output shaft other than the mounting surface should be painted or protected by other types of rust processing flow when the current passes through the input and output shaft. When the spark generated by the contact between the rotating bodies causes micro-etching on the surface of the rotating body, the output shaft and the ball groove in the cam transmission generate fine indentations which cannot be repaired. This phenomenon is called electric erosion. Even at currents less than 1 volt, current spikes can induce an eclipse. 2. Therefore, if the product has an opportunity to contact the current, please ensure insulation. Long-term corrosion can cause vibration and working noise in the transmission parts of the product, and eventually shorten the service life. When connecting the motor, use a rubber coupling with high insulation. The use of rubber V-belts, timing belts, etc. can effectively prevent the occurrence of electrical corrosion.
(three) dust
Air dust in the general work shop does not have any effect on product use. However, if the air quality of the environment is too poor, dust and other substances in the air will accelerate the aging of the seal and eventually lead to oil leakage. Therefore, if the working environment is too dusty, it is recommended to use plastic or stainless steel protection to achieve dust prevention, but be careful not to affect heat dissipation.
Third, the test
Automated machines using the CAMDEX indexer are quite complex in design. For these machines that move together with each other to create a mutual movement, most of the assembly problems and interferences are generally attributed to imperfect assembly and commissioning plans. Therefore, after assembly, the product needs to be tested by manual operation. If the problem is found to be adjusted, then the continuous operation test machine is performed.
(1) Test operation, manual operation must be carried out after assembly to ensure smooth operation of the product. During operation, pay attention to whether the angle and position are accurate, whether the torque generated by friction is too large, and whether it is matched with the surrounding components. If the motor cannot be operated manually due to space problems or on a large machine, the motor can be started and checked at a slight or near idle speed. (2) Continuous operation, after the test operation is normal, it should be further tested by continuous operation. Slowly adjust from the low speed operation to the speed that needs to be operated, and pay attention to whether abnormal sound, vibration, temperature rise and oil leakage occur. After confirming the error, check the presence of initial wear and precision changes with long-term operation.
Fourth, the use of the input shaft
(1) The setting of the transmission coefficient, the performance parameters of the CAMDEX indexer, such as the maximum torque, are measured according to their use in the optimal operating environment. The so-called optimal operating environment is no backlash, no deflection, and no bending between the shafts during operation. Any of the above will cause the rotation to be unstable, which will affect the maximum torque value. Therefore, in order to achieve the best performance of the CAMDEX indexer, it is important to determine the stability of the force shaft during operation.
In actual use, the instability of the rotation cannot be completely eliminated. The main causes of unstable rotation are: 1. Inertia phenomenon; 2. Chain drive or polygonal motion; 3. Bending deformation or axial reaction between shafts; 4. Change in rotational speed caused by load size change. All of the above will have a negative impact on the service life and accuracy of the CAMDEX indexer, where inertia should be minimized. If chain drive or polygonal motion is added, the situation will be more serious.
Therefore, to reduce the noise and vibration generated by the operation, please avoid:
1. Chain and gear transmission Noise and vibration generated by the chain and gear during operation, and inertia. Not recommended for use. Gears can be used at low speeds if lubricated 2. Pneumatic or hydraulic motors, these devices do not provide reliable and continuous input speed, which has a negative impact on the stability of the CAMDEX indexer operation. Consider the following solutions: 1. Using a worm gear reducer The use of a worm gear reducer directly connected to the input shaft avoids the extension of the input shaft and reduces vibration, while also contributing to the power output efficiency. 2. Using the timing belt The timing belt is the best choice for connecting the CAMDEX indexer for three reasons: it is not easy to slip, ensuring that it runs synchronously with the machine. The tensile force required for locking is small, so the load on the input shaft is also relatively reduced. Maintenance free; the noise during use is much lower than gears and chains. At the same time, the use of a larger synchronous wheel helps to stabilize the indexing position of the belt during running.
An indexing cycle begins when the direction of the keyway of the input shaft is toward and perpendicular to the output shaft. This point depends on the reference position (0°) and is half of the rest period. The indexing period is a period in which the stationary indexing is stationary. Assuming that the drive is θ, when the input shaft rotates the reference position in the clockwise or counterclockwise direction and then continues to rotate in the same direction (180-0/2) degrees, the indexing cycle begins: the output axis is from One station rotates to another station (Index). After turning θ degrees, it enters the stationary period (Dwell). In the action stroke diagram, the reference position is represented as 0°, which is the stop position of the output shaft, that is, the start of the stroke. The CAMDEX indexer is produced according to the customer's desired action schedule.
When installing on the input shaft and the output shaft, such as discs, gears, synchronous gear reducers, etc., be careful not to hit them with a hammer, otherwise the internal components such as cams or bearings may be damaged. Refer to the following tips when installing:
1. The keyway and key of the input and output shaft are produced according to the JISB13011976 standard. Please make sure that the matching parts are processed according to this standard to ensure a smooth installation. 2. There should be no gap between the input shaft and the matching components such as the synchronous wheel, otherwise the slight vibration generated during operation will accelerate the wear of the shaft surface. Applying butter to the shaft surface can effectively prevent the occurrence of fretting. The positioning accuracy of the output shaft of the CAMDEX indexer is expressed when the output shaft is at the stop cycle. Therefore, when performing the inter-axis correction positioning, please run the indexer for several cycles and ensure that the output shaft is at the stop position. Otherwise, misplacement is very easy to occur.
The output shaft end can fix the disc, the conveyor belt, the connecting flange, the gear, the gapless coupling, etc.: the input shaft directly or indirectly installs the supporting transmission such as the motor and the reducer.
The output shaft generates inertia torque when it is stopped to maintain positioning accuracy. When the transmission is fixed to the output shaft, the steel has a good fixing screw to prevent distortion and deformation after long-term use, and the device is loose. At the same time, care should be taken not to exceed the load that the indexer can withstand, so as not to affect its service life and accuracy.
