Comparison of maintenance costs between hard toothed reducer and soft toothed reducer

The maintenance costs of hard-toothed reducers and soft-toothed reducers are as follows:

• Maintenance cycle :

• The gears of the hard tooth surface reducer have high hardness and good wear resistance. Under normal working conditions, the wear speed is relatively slow and the maintenance cycle is long. Generally, it can run for a long time before a comprehensive inspection and maintenance is required.

• Because the tooth surface of soft tooth surface is softer, it is more likely to cause wear and other problems. In order to ensure its performance and service life, inspections and maintenance are required more frequently. For example, inspections may be required every short time (such as several months), while hard tooth surface reducers may need to be inspected to the same level for one year or more.

• Component replacement cost :

• The gears and other key components of the hard-toothed reducer use high-quality alloy steel and undergoes complex heat treatment processes, which is costly. Therefore, once the gears and other components need to be replaced, the cost is relatively expensive. However, due to its good durability, the replacement frequency of parts is low under normal use.

• The gear material and manufacturing process of soft-tooth surface reducer are relatively simple, and the parts cost are relatively low. However, because it is easy to wear, it may be necessary to replace gears, bearings and other components more frequently. In the long run, the total cost of replacement of parts may not be low. For example, in some long-term operating equipment, soft-tooth surface reducers may need to replace gears every few years, while hard-tooth surface reducers may not need to replace gears throughout the life cycle of the equipment.

• Lubrication system maintenance cost :

• Hard-toothed speed reducers usually use oil pool lubrication and natural cooling. If necessary, they can use circulating oil lubrication or forced cooling. The lubrication system is relatively complex and requires high requirements for the quality and cleanliness of the lubricant. It is necessary to regularly check the quality and oil level and replace it. The cost of lubricant is also relatively high.

• Soft tooth surface reducers mostly use simple lubrication methods, such as grease lubrication, which does not require complex cooling measures. The maintenance of the lubrication system is relatively simple and the cost of lubricating oil is also low. However, it also requires regular inspection and replenishment of grease, and due to the short maintenance cycle, the amount of grease may be used relatively large.

• Maintenance technology cost :

• The hard tooth surface reducer has a complex structure. Once a failure occurs, it requires high technical level and maintenance equipment of the maintenance personnel. Professional technicians and specific maintenance tools, testing equipment, etc. may be required, which will increase the labor cost and technical cost of maintenance.

• The maintenance of soft-toothed reducer is relatively simple. Ordinary maintenance personnel can perform maintenance after a certain amount of training. The requirements for maintenance equipment are not high, so the technical cost of maintenance is relatively low.

Overall, although the initial purchase cost of hard tooth surface reducer is high, the maintenance cost during long-term use is relatively low due to the long maintenance cycle and few parts replacement; the initial cost of soft tooth surface reducer is low, but it requires frequent maintenance and replacement of parts, so the maintenance cost for the entire life cycle may not be low.
