Recently, the Beijing Institute of Mechanical and Electrical Engineering of the General Machinery Institute undertook the acceptance of the “2000KN Vertical Cold Swing Rolling Machine Development Research†project. The 2000KN vertical cold pendulum machine develope ......
To have sufficient pre-tightening force, the tightening mechanism of the bolt can be obtained by converting the torque applied to the bolt. The pre-tightening force causes the bolt to generate tensile stress, and at the same time, the coupled member generates compressive stress for fastening pur ......
1. Anti-trailing function: The infrared light band detection area in the channel can be used to adjust the switch state according to the customer's accuracy requirements. The application of the light belt to adapt to different requirements avoids the point-to-point infrared detector being easil ......

1 Introduction AC winding motors used in mine hoists are usually speed-controlled by switching their rotor resistance. However, the electric motor relies on the low speed obtained by the rotor resistance and its operating characteristics are soft. When the lifting container passes a given decele ......
