WQ-JXZH mechanical transmission optimization Comprehensive Test Bench change bench is a new product of our company and China Hunan monitoring and testing equipment units designated as joint development, monitoring and control accuracy (0.2), monitoring data is stable; inverter technology with digital PID control technology, constant speed input, constant torque output; can be synchronized in a timely manner or continuous automatic sampling, automated data processing, control box condition results automatically output. Bench change applies to mechanical design, mechanical design, curriculum design innovative, comprehensive and innovative experiment set up, is one of the important open innovation laboratory equipment, can also be used for graduate research and external technical services. Main technical characteristics: (1) The test bench for mechanical transmission device performance parameters, such as speed, torque, and draw out the gear ratio, torque, speed, power and other curves, through different mechanical transmission performance parameter curve In contrast, comparative analysis of the performance characteristics of different transmission schemes. 2. The test-bed modular design, high capacity variant has better maneuverability and secondary development. Can lap six kinds of basic single-stage transmission: ◎ V belt drive; ◎ belt drive; ◎ chain drive; ◎ worm drive; ◎ cycloid drive; ◎ cylindrical gear. Can also be a combination of two more lap, three transmissions, students choose to create the conditions for the experimental program. In addition, also based on research or teaching needs, another expansion of the experimental apparatus is configured using the control part of the experiment station to detect the transmission performance tests conducted. 3. The test stand by the FM frequency motor drive with magnetic brakes as the loader. Speed ??loader inverter motor torque and start and stop the program, available through computer control, can also be manually adjusted by bench panel. Computer control, can achieve a constant speed and experimental requirements loader motor torque constant. 4. The bench test card using the torque and speed, synchronous capture input and output torque and speed, high accuracy. 5. Experimental software can dynamically timely acquisition, display of experimental data, can be set at any one time sampling or continuous sampling, automatic data processing, automatic output results. 6. The bench is a steel cabinet structure, work platform with cast iron, the thickness of 60mm, up to two flat precision. With plexiglass shields. Cold-rolled steel were confirmed by spray.
