彈簧疲勞拉力機的特點及用途

Features and usespring fatiguetensile machine

機械式彈簧疲勞拉力機是由驅動系統(tǒng)、傳動系統(tǒng)、控制顯示等系統(tǒng)組成，適用于各 種螺旋彈簧的疲勞性能試驗。該拉力機由電磁調速系統(tǒng)控制電機運行，通過偏心裝置帶動連桿使 壓板往復上升、下降，完成對彈簧的往復壓縮疲勞拉力試驗。該機無污染、效率高，具有較寬的調頻 范圍和試驗空間，配上合適的輔具，可完成不同規(guī)格的彈簧疲勞試驗。該拉力機通過單片機控制，實現試驗次數達到自動停機功能，該機集成度高，結構簡單，故障率低，性能穩(wěn)定、可靠，操作 簡單。
