Can be widely used in metallurgy, mining, lifting, light industry, chemical, transportation, construction and other mechanical equipment speed reduction mechanism.

The helical gear advantages and disadvantages,gears are one of the most important components in large-scale industrial equipment. A very important application of helical gear spur gear transmission. The helical gear advantages and disadvantages transmission has good meshing performance, which makes the transmission process tend to be stable and the noise is small. It has the advantages of relatively large coincidence degree, relatively low load between teeth, thereby improving the ability of the gear to withstand pressure, and the like. Helical gear transmission has important applications in the field of life and production. The helical gear advantages and disadvantages.Through the understanding of the characteristics and application of the helical gear transmission, we have a deeper understanding of the helical gear transmission and facilitate future use. The helical gear reducer is a novel reduction gearing. It adopts the advanced design concept of the optimized module combination system. The helical gear advantages and disadvantages.It is a helical gear reducer with small size, light weight, large transmission torque, stable starting, fine transmission ratio, and can be connected according to user requirements and various installation positions. The helical gear advantages and disadvantages,and the carrying capacity is strong and durable.

The characteristics and application of dc motor

The characteristics and application of dc motor:

    Main advantages: Compared with AC three-phase asynchronous motor, the characteristics and application of dc motor has good starting characteristics and speed regulation characteristics, the characteristics and application of dc motor ,which is convenient for speed regulation. Therefore, for the production machinery with high starting and speed regulation performance, DC motor drive is often used.The characteristics and application of dc motor main disadvantage: you need to configure the DC power supply, the price is relatively expensive.

The characteristics and application of dc motor:

   1) When the production machine needs to maintain a constant speed under different load conditions and the speed can be adjusted, a DC motor can be used. For example, a shunt DC motor can be used to drive a grinding machine, a planer, and the like.
