1. the current factors affecting the energy consumption of traditional systems

(I) structure elements: At present, machinery and equipment have been widely used in various industries, and play an important role in promoting the effectiveness of enterprise production and work. One of the main factors that cause the large energy consumption of the transmission system is the unreasonable internal structure of machinery and equipment. The main mode of operation of machinery and equipment is automatic control system, and different machinery and equipment have great differences in content structure. At present, the transmission mode of mechanical equipment is mainly divided into chain transmission, belt transmission and gear transmission. Compared with the actual application of mechanical equipment, the joint coefficient between mechanical transmission system components is relatively low, and the energy consumption of the transmission system is too large. The operating efficiency of mechanical equipment is also affected to a certain extent. The unreasonable transmission combination mode also leads to the problem of excessive energy consumption.

(II) operating factors: In the actual use of mechanical equipment, operating factors are also one of the factors that cause excessive energy consumption of the transmission system. Some operators do not master the correct operation standards in the actual operation process, the consumption of equipment parts is easy to become larger, and the energy consumed by the operation of the traditional system is also larger. For example, in the actual operation of CNC machine tools, some workers cannot effectively control the spindle, and the transmission components are worn out during operation, which seriously affects the operation of the overall equipment of the CNC machine tool. In some manual mechanical equipment, the working efficiency and energy consumption of the transmission system have a direct impact on the actual working level of the operator, thus increasing the energy consumption of the system.

(III) maintenance factors: late maintenance factors on the energy consumption of mechanical equipment transmission system also had a great impact. In this context, the production efficiency is constantly improving, but with the increasing load of mechanical equipment, the failure rate is rising, and the number of maintenance is rising. If the maintenance is improper, the energy consumption of the traditional system will continue to increase, which is easy to cause the corresponding security risks.

Energy-saving Design and Transformation Measures of 2. Mechanical Transmission System

As the core key of mechanical equipment, the operation efficiency of the transmission system directly affects the overall operation effect of the mechanical equipment. It can be seen that the energy consumption of the transmission system is reduced and the work efficiency is improved. Combined with the current common transmission mode of mechanical equipment, to realize the energy-saving transformation of mechanical equipment, based on the actual situation, formulate scientific and reasonable energy-saving design and transformation measures of the transmission system, and summarize the following energy-saving design and transformation strategies.

(I) gear transmission: Relevant designers need to clarify the main core, stabilize the instantaneous angular velocity ratio of the gear, and ensure that the rotation axis of the transmission system is fixed in actual operation when designing fixed-axis gears for energy saving. The gear transmission system mainly relies on the power generated by the rotation fluctuation of the gears of mechanical equipment. Based on the energy-saving design and transformation of the gear transmission system, relevant designers need to base on the actual operation of the equipment transmission system in the actual energy-saving design process. For example, from the perspective of the transmission system elements, in-depth analysis of the spatial movement, relative movement and plane movement generated by the two gears during the actual design and transformation process, combined with the transmission type of gear, scientific and detailed design, through the design of the best gear combination, so as to effectively reduce the energy consumption of gear transmission. On this basis, it is divided into space gear transmission and plane gear transmission. Combined with the actual operation of the equipment, the effective mode of mechanical equipment transmission is selected.

(II) belt drive: As one of the commonly used methods of mechanical equipment transmission system, belt drive has the characteristics of simple installation and simple operation. However, in the actual operation of the transmission system, the belt drive after a long time of operation, based on high operation and high temperature environment, prone to belt fracture, loss and other problems. Therefore, it is necessary to improve the importance of belt drive operation mode to optimize energy-saving design. So as to improve the stability of the transmission system to lay a good foundation.

The above introduction is mechanicalDrive systemEnergy-saving design and transformation, therefore, to improve the energy-saving design and transformation of the transmission system, the effective energy-saving design and transformation of the mechanical transmission system plays an important role in improving the life of mechanical equipment and promoting the productivity of mechanical equipment. Through children's scientific and reasonable energy-saving design measures, the effective energy-saving of the transmission system is realized, and a good foundation is laid for the improvement of the economic benefits of the enterprise.
