Do you know the type and maintenance of the reducer?

As an important part of the machinery industry, the operation of the reducer is directly related to the efficiency and quality of the operation of the entire unit. With the country's strong support for the intelligent manufacturing industry, especially the development of the industrial robot industry, the output of the reducer has increased. In 2019, the output of China's reducer increased significantly, with the output reaching 8.517 million units, a year-on-year increase of 51.28%; in 2020, the output of China's reducer reached 9.17 million units, a year-on-year increase of 7.67%.

Gear manufacturers

The gear reducer has the characteristics of small size and large transmission torque. The gear reducer is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is finely graded to meet different working conditions and realize mechatronics.

There are many types of gear reducers, mainly cylindrical gear reducers, cone-cylindrical gear reducers, planetary gear reducers, gear-worm reducers, special gear reducers, etc.

1. Main types of gear reducers

1. Planetary gear reducer

There are many types of planetary gear reducers, including general planetary gear reducers, various small tooth difference reducers, harmonic gear reducers and three-ring reducers.

The advantage of this type of reducer is that it can be made into single-stage, double-stage and multi-stage reducers, so the transmission ratio range is large, and it has the characteristics of compact structure, light weight, large bearing capacity and small outline size. However, its structure is complex, the manufacturing precision is high, the assembly and maintenance are difficult, and the price is high.

2. Conical-cylindrical gear reducer

Conical-cylindrical gear reducer is a transmission device used for the vertical arrangement of the input shaft and the output shaft. The first-stage transmission of this type of gear reducer is a Gleason spiral bevel gear, and other tooth shapes can also be used. The first and third-stage transmissions are involute cylindrical helical gears

The gears and bearings of this type of reducer are generally splash lubricated and naturally cooled. This type of reducer has the advantages of high bearing capacity, low noise, small size, light weight, high efficiency and long service life, and is widely used in metallurgy, coal, transportation, building materials and other mechanical equipment.

3. Cylindrical gear reducer

Cylindrical gear reducers are mainly divided into involute cylindrical gear reducers and arc cylindrical gear reducers. Among them, involute cylindrical gears are widely used, and can be divided into straight teeth, helical teeth and herringbone teeth.

Second, the use and maintenance of gear reducer

1. Before starting the gear reducer, check whether the oil level in the reducer meets the requirements. Open or replace the ventilation cap according to the prompts to make it ventilated smoothly, and check whether the rotation is flexible.

2. Before the load test, it should be run with no load for about half an hour. After confirming that the no-load is fault-free, it can be loaded and run. The test machine should always check the operation: there should be no abnormal shock, vibration, no seepage or oil leakage. The temperature rise shall not exceed 60 ℃, and the high oil temperature shall not exceed 100 ℃ (inspection should also be carried out during daily work).
