Applications, instructions for use, and precautions of cycloidal pinwheel reducers (Part 1) Applications: Cycloidal pinwheel reducers operate based on the principle of cycloidal pin-tooth meshing and planetary transmission; therefore, they are also commonly referred to as planetary cycloidal reducers. These reducers can be widely used in industries such as petroleum, environmental protection, chemical processing, cement production, material handling, textiles, pharmaceuticals, food processing, printing, lifting operations, mining, metallurgy, construction, and power generation, serving as drive or speed-reduction devices. Its unique smooth structure allows it to replace conventional cylindrical gear reducers and worm gear reducers in many applications. Therefore, planetary cycloidal pinwheel reducers are widely used across various industries and fields, enjoying great popularity among users. (II) Operating conditions: 1. Cycloidal pinwheel reducers can be used in continuous operation, and they can operate in both forward and reverse directions. 2. The rated speed of the input shaft is 1500 revolutions per minute; when the input power exceeds 18.5 kilowatt-hours, it is recommended to use a 6-pole motor with a speed of 960 revolutions per minute. 3. The operating position of horizontally mounted cycloidal pinwheel reducers is always horizontal. During installation, the maximum horizontal tilt angle is generally less than 15°. At angles exceeding 15°, other measures should be taken to ensure adequate lubrication and prevent oil leakage. 4. The output shaft of the cycloidal pinwheel reducer must not be subjected to large axial or radial forces; when such forces are present, other measures must be taken. (III) Lubrication: 1. Under normal circumstances, horizontal cycloidal reducers are lubricated by an oil bath; the oil level should be maintained at the midpoint of the oil sight glass. In harsh operating conditions or when the ambient temperature is high, circulating lubrication may be employed. 2. At room temperature, 40# or 50# machine oil is generally used to lubricate cycloidal pinwheel reducers. To enhance the performance of the reducer and extend its service life, it is recommended to use 70# or 90# extreme pressure gear oil. When operating under high or low temperature conditions, the choice of lubricating oil should also be reconsidered. 3. When installing a vertical planetary cycloidal pinwheel reducer, it is essential to prevent the oil pump from running out of oil, so as to avoid damage to the reducer’s components. 4. To refuel, simply rotate the vent cap on the top of the housing to add fuel. To drain the oil, simply turn open the oil drain plug at the bottom of the housing to release the contaminated oil. No lubricating oil is present inside the reducer at the time of shipment. 5. When the reducer operates for 100 hours for the first time after refueling, new oil should be added (and any contaminated oil inside must be flushed out). Thereafter, the oil should be changed every six months under an 8-hour work schedule. In cases where operating conditions are harsh, the oil change interval may be shortened appropriately. Practical experience has shown that regular cleaning and oil changes of the reducer—such as every 3 to 6 months—play a crucial role in extending its service life. During use, lubricating oil should be replenished frequently. 6. The new reducers issued by our factory have been lubricated with grease, which should be replaced every six months. Aluminum disulfide-2# or 2L-2# lithium-based lubricating grease is used for the grease. (IV) Installation: 1. When installing coupling, pulley, sprocket, and other connecting components on the output shaft of the cycloidal reducer, direct hammering is not allowed, as the structure of the reducer’s output shaft cannot withstand axial hammering forces. Screws can be inserted into the screw holes at the shaft ends to press the connecting components in place. 2. The shaft diameters of the output shaft and the input shaft shall comply with the standards specified in GB1568-79. 3. The lifting ring screws on the reducer are intended solely for lifting the reducer. 4. When installing the reducer on the base, it is necessary to calibrate the elevation of the reducer’s installation centerline, its levelness, as well as the relevant dimensions of its connected parts. The concentricity of the calibrated drive shaft should not exceed the range permitted by the coupling. 5. When calibrating the reducer, steel shims or cast iron shims can be used; no more than three shims should be used at once in terms of height. Cast iron can also be utilized, but flat shims should be used after the reducer has been calibrated. 6. The placement of shims should be such as to avoid deformation of the structure; they should be arranged symmetrically on both sides of the foundation bolts, with enough spacing between them to allow free flow of the grout during irrigation. 7. The cement slurry should be poured densely, without any bubbles, voids, or other defects
