Cycloidal pinwheel reducers are currently the leading product in the domestic speed reducer industry. The transmission principle of a cycloidal pinwheel reducer is based on a planetary transmission system using an exocycloidal wheel and pin teeth meshing, designed according to the principle of exocycloidal meshing. After decades of development, its theory has been perfected, the product is mature, and the products have been standardized and serialized. Due to its advantages such as small size, light weight, wide transmission ratio range, high transmission efficiency, smooth transmission, low noise, and reliable operation, cycloidal reducers are widely used in many sectors including metallurgy, mining, petroleum, chemical, shipbuilding, environmental protection, light industry, food, textiles, printing and dyeing, lifting and transportation, and military industry.
The industrialization of internal cycloidal reducers only requires solving the problem of specialized processing equipment for the internal cycloidal wheel. Production can be carried out in existing cycloidal reducer manufacturers or general machinery plants. High-power internal cycloidal reducers can be produced in large machinery plants in mining, metallurgy, and chemical industries, or new specialized internal cycloidal reducer plants can be built. Due to the superior performance and broad market prospects of internal cycloidal reducers, in addition to occupying the existing domestic and international cycloidal reducer market, there will be even greater market demand as the power of internal cycloidal reducers increases. If the production of internal cycloidal reducers accounts for 11/3T of the reducer market in 2010, its sales revenue will reach 38 million yuan, generating a profit of approximately 7.6 million yuan. If it accounts for 30/3T of the market share in 2015, its sales revenue could reach 1.5 billion yuan, generating a profit of approximately 300 million yuan.
Due to outdated technology and lack of competitiveness, existing cycloidal reducer products have very low profit margins. According to industry statistics, in 2005, the industry's output was 605,000 units, with sales revenue of 2.92 billion yuan and total profit of 160 million yuan. It is projected that by 2010, the industry's output will reach 850,000 units, sales revenue will reach 3.8 billion yuan, and total profit will reach 300 million yuan, with profits accounting for only 6-81% of sales revenue.
The cycloidal pinwheel planetary reducer possesses independent intellectual property rights and high performance. Its profit margin can account for 20% of sales revenue. In 2015, the production volume of cycloidal reducers reached 30% (approximately 300,000 units) of the gear reducer market share, which could increase sales revenue by 850 million yuan and profit by 600 million yuan. Based on 50kg/unit, it could save 15,000 tons of materials. If the product can be upgraded and replaced as soon as possible, it will generate significant economic and social benefits.
