減速機是小型攪拌車的核心關鍵零部件，在攪拌運輸車加料、運輸、卸料過程中，擔負起攪動混凝土以防止出現離析，從而保證混凝土質量，增加運輸距離的作用。為其持續提供動力，以滿足攪動混凝土所需扭矩及轉速，同時承受來自滿載攪拌筒軸向及徑向的自重載荷和沖擊載荷。

The reducer is the core and key part of the small mixer truck. During the feeding, transportation and unloading of the mixer truck, it plays the role of stirring the concrete to prevent segregation, so as to ensure the concrete quality and increase the transportation distance. Provide continuous power for it to meet the torque and speed required to stir the concrete, and bear the axial and radial self weight load and impact load from the fully loaded mixing drum.

尤其是攪拌車在高速剎車、轉彎、下坡等工況時，減速機將受到強大的沖擊載荷。柔性機構在減速機中與行星齒輪傳動機構有著同樣重要的作用，不僅承擔來自攪拌車的軸向載荷、徑向載荷，吸收減速機與攪拌罐的安裝誤差、運輸過程中的沖擊形變位移，還擔負起保證齒輪傳動平穩性、均載性的作用。

Especially when the mixer truck is under high-speed braking, turning, downhill and other working conditions, the reducer will be subjected to strong impact load. The flexible mechanism plays the same important role in the reducer as the planetary gear transmission mechanism. It not only undertakes the axial load and radial load from the mixer, absorbs the installation error of the reducer and the mixing tank and the impact deformation displacement in the transportation process, but also plays the role of ensuring the stability and load uniformity of the gear transmission.

為了驅動攪拌筒轉動，原始的時候采用鏈條鏈輪傳動方式，后來采用軸承聯軸器的傳動方式，目前應用廣泛的為液壓系統加減速機的傳動方式，更好地適應了工況的要求。

In order to drive the mixing drum to rotate, the chain sprocket transmission mode was adopted in the original time, and then the bearing coupling transmission mode was adopted. At present, the transmission mode of hydraulic system plus reducer is widely used, which better meets the requirements of working conditions.

減速機作為攪拌筒的一個重要支撐點，大約要承載攪拌筒的2/3的重量，加上行駛過程顛簸產生的附加載荷，這就要求減速機有很大的承載能力。隨著對運輸混凝土質量要求的提高，且運行工況中勻速轉動，對減速機的性能要求也逐步提高。

As an important supporting point of the mixing drum, the reducer should bear about 2 / 3 of the weight of the mixing drum, plus the additional load generated by the bumps during driving, which requires the reducer to have a great bearing capacity. With the improvement of the quality requirements for transporting concrete and the uniform rotation in the operating condition, the performance requirements for the reducer are also gradually improved.

小型攪拌車實現輸送的高效能和全部機械化作業，這樣很大地提高了勞動生產率和施工質量，當然其相關部件起到很大的作用，定期的維護要做好，更多內容就來網站www.www.boy7up.cn關注吧！
