Types of transmission systems for construction machinery (analysis of mechanical transmission components)

The transmission component is one of the most important core components of Chinese construction machinery, known as the heart of construction machinery. Especially for walking operations powered by traction, construction machinery is even more important. In terms of value, the proportion of transmission components is also quite large. Taking a typical 5t loader as an example, with twin turbine Torque converter and simple planetary transmission, plus ordinary caliper disc brake drive axle, the current procurement cost is about 40000 to 60000 yuan, with an average of 50000 yuan. The overall cost is about 200000 yuan, so the transmission components account for about 25% of the overall cost. If high-tech transmission components are used, this proportion is even higher, accounting for about 30% or more. Therefore, transmission components play a crucial role in engineering machinery.

Gear reducers are becoming increasingly popular due to their longer service life and economic characteristics

The normal operation of the gear reducer is restricted and has had a serious impact on the gear reducer system. The key to fully utilizing the function of gear reducers is to improve their firepower. We usually improve the firepower of the gear reducer by cooling the gear reducer system. Jin Changcheng informs everyone that under normal conditions, the methods for increasing the rated cooling of gear reducers mainly include cooling fans, water-cooled coils, and several methods for external lubrication. The principle and technology of gear reducers When equipped with servo specialized gear reducers, high positioning accuracy (accuracy) is required under normal conditions. In addition to being able to accept large loads, servo gear reducers can also achieve particularly high transmission accuracy, with output end backlash accuracy reaching less than 1 point (imported SEW, PSF small series).

What are the structural components and classifications of rotary hydraulic motors?

Rotary hydraulic motor is a commonly used hydraulic transmission device, widely used in engineering machinery, agricultural machinery, petroleum drilling equipment, and various automated production lines. The characteristics of rotary hydraulic motors are compact structure, light weight, large output torque, and wide speed range. So, what are the structural components and classifications of rotary hydraulic motors? Structural composition The rotary hydraulic motor is mainly composed of main components such as the motor housing, the motor shaft, the oil cylinder, and the reduction gear. Among them, the motor shaft is the core component of the rotary hydraulic motor, which converts hydraulic energy into mechanical energy by connecting the internal gears and reducers of the motor to achieve output torque and speed control. The oil cylinder is another important component of the rotary hydraulic motor, which can control the inlet and outlet of hydraulic oil and achieve control functions such as start stop and speed adjustment of the rotary motor. classification Rotary hydraulic motors are divided into three types according to their transmission methods: external tooth type, internal tooth type, and planar type. Among them, the external toothed rotary hydraulic motor adopts a gear transmission method, with high output torque and power, and is commonly used in engineering machinery and agricultural machinery; The internal toothed rotary hydraulic motor adopts the internal toothed method, which is more compact than the external toothed method and is commonly used in petroleum drilling equipment and robot manufacturing; The planar rotary hydraulic motor adopts gear to plane friction transmission, suitable for low speed and high torque situations. In addition, rotary hydraulic motors can also be classified according to their application fields. For example, planetary rotary hydraulic motors are commonly used in construction machinery, which have the characteristics of compact structure, light weight, and high output torque, and can be widely used in construction machinery such as excavators and forklifts. In the field of Naval architecture, swing rotary hydraulic motors are commonly used, which are suitable for steering and positioning control of large ships. In short, as an important hydraulic transmission device, the rotary hydraulic motor has a variety of structural components and classification methods. According to different application scenarios and requirements, selecting different types of rotary hydraulic motors can better achieve the effect of hydraulic transmission.
