减速机是小型搅拌车的核心关键零部件，在搅拌运输车加料、运输、卸料过程中，担负起搅动混凝土以防止出现离析，从而保证混凝土质量，增加运输距离的作用。为其持续提供动力，以满足搅动混凝土所需扭矩及转速，同时承受来自满载搅拌筒轴向及径向的自重载荷和冲击载荷。

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.

尤其是搅拌车在高速刹车、转弯、下坡等工况时，减速机将受到强大的冲击载荷。柔性机构在减速机中与行星齿轮传动机构有着同样重要的作用，不仅承担来自搅拌车的轴向载荷、径向载荷，吸收减速机与搅拌罐的安装误差、运输过程中的冲击形变位移，还担负起保证齿轮传动平稳性、均载性的作用。

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.

为了驱动搅拌筒转动，原始的时候采用链条链轮传动方式，后来采用轴承联轴器的传动方式，目前应用广泛的为液压系统加减速机的传动方式，更好地适应了工况的要求。

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.

减速机作为搅拌筒的一个重要支撑点，大约要承载搅拌筒的2/3的重量，加上行驶过程颠簸产生的附加载荷，这就要求减速机有很大的承载能力。随着对运输混凝土质量要求的提高，且运行工况中匀速转动，对减速机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.
