The invention discloses an electricity consumption information monitoring method and system based on hardware industry electric power big data, and belongs to the technical field of electric power information monitoring, and the method comprises the steps: S1, calculating segmented energy consumption data and classified energy consumption data based on electricity consumption data; s2, correcting the classified energy consumption data based on the working duration and rated power of the production equipment, and detecting whether the classified energy consumption data is abnormal or not; s3, constructing a fitting function by using the classified energy consumption data, the raw material feeding data and the finished product data, and judging whether the fluctuation information is abnormal or not; s4, judging the relationship between the power consumption data of the hardware feeding equipment and the threshold value to determine whether to adjust the feeding speed; s5, calculating the number of theoretical products based on the power consumption of the heating equipment, and adjusting the feeding speed if the actual number is smaller than a theoretical value; and S6, judging whether the heating equipment is abnormal or not according to the load current of the die forging equipment, and sending warning information. According to the scheme, multi-level power fault analysis is carried out on the hardware industry, so that the coverage range of power fault detection can be remarkably expanded.

This invention belongs to the field of bearing technology, specifically providing a high-speed bearing and motor for an electric drive assembly. The high-speed bearing for an electric drive assembly includes a bearing housing, rolling bearings, an oil-pushing assembly, and a sealing element. The rolling bearings are installed in the mounting cavity of the bearing housing, and an oil reservoir is provided at the bottom of the mounting cavity. The oil-pushing assembly is located in the oil reservoir. Before the motor cold starts, the oil level is raised by a piston, achieving complete immersion of all rolling elements. Subsequently, the piston descends, lowering the oil level. Before the motor stabilizes, the lubricating oil level in the oil reservoir has dropped below the center position of the lowest rolling element. This design ensures that an effective oil film is established between the rolling elements and the inner and outer rings of the bearing at the moment of motor startup, eliminating the risk of dry friction. It also avoids the high-speed rotation of the rolling elements causing violent agitation of the oil, which could lead to an increase in oil temperature.

The utility model provides a protective gas device of metal material vacuum heat treatment equipment, which comprises the vacuum heat treatment equipment, the protective gas device is arranged on one side of the vacuum heat treatment equipment, the protective gas device is connected with the vacuum heat treatment equipment through an inflating device, and the vacuum heat treatment equipment comprises a spline shaft which is of a hollow structure. The upper end of the air blowing pipe is communicated with a protective gas device through a connecting pipe, and the lower end of the air blowing pipe is connected with an air blowing head which is arranged in vacuum heat treatment equipment.
