It is understood that China's operating income in the construction machinery industry reached 668.1 billion yuan in 2019, an increase of 12% over the same period last year. With a stable and friendly macroeconomy and stable fixed asset investment in China, the effect of industrial transformation and upgrading is further demonstrated. Under the superimposed influence of many factors, the construction machinery market is reappearing at a high speed.
According to relevant statistical data, the sales volume in the first half of 2020 is improving month by month. In January, the sales volume of 12 key enterprises' main products decreased by 20.5% year-on-year, decreased by 44.8% year-on-year in February, and increased by 2.34% year-on-year in March. The year-on-year decline of 14.1% in January-March; It added 38.3% in April and 0.49% in January-April. It added 40.9% in May and 8.13% in January-May. It added 51.7% year-on-year in June and 14.4% year-on-year in January-June.
With China's emphasis on machinery manufacturing, the process of strict localization of equipment is speeding up, as well as urban renovation and venue construction
The construction project starts, the reducer market prospect is good, the whole reducer industry will hold the rapid development trend, especially the use of gear reducer demand will increase substantially, which is affected by the imported equipment mostly choose gear reducer to use.
Like many types of the reduction gear, a gear reducer is a power transfer arrangement that is used to reduce speed and add torque.
Heavy machinery to gear reducer, planetary gear reducer, worm gear reducer and cycloidal gear reducer and other kinds of special transmission devices.
No matter which reducer is used, I believe that under the influence of the equipment demand in the mechanical industry, the development trend of the reducer will be:
1: High level, high performance. Gear selection carburized quenching, grinding teeth, bearing capacity more than 4 times, small volume, lightweight, low noise, high efficiency, high reliability.
2. Modular combination planning. Priority is given to the selection of basic parameters, neat standards of dimensions, strong versatility and interchangeability of parts, easy expansion and pattern renovation of the series, conducive to the arrangement of mass production and cost reduction.
3. Diversified types and multiple variation plans. Get rid of the traditional single base device method, add hollow shaft suspension type, floating support base, motor and reducer integrated connection, multi-azimuth device surface and other different types, expand the use range.
