行星齒輪減速器-行星齒輪減速器齒輪承載能力的計算
漸開線少齒差行星減速器與普通圓柱齒輪減速器、蝸輪減速機相比，具有體積小、重量輕、傳動比大、效率高、承載能力大、運行可靠和壽命長等優(yōu)點；與擺線針輪行星減速器相比，除具有上述優(yōu)點以外，在加工方面，可利用通用刀具在通用齒輪加工機床上加工．因而具有成本較低等優(yōu)點。而在承載能力方面是怎樣呢?本文就利用有限元法對二齒差行星減速器齒輪承載能力進行分析討論。
少齒差行星減速器是內(nèi)嚙合傳動。一般認為，它的一對嚙合齒面分別為凸齒面和凹齒面，兩者的曲率中心在齒面同一側(cè)，齒面凹向相同，曲率半徑差很小，接觸變形致使接觸面積較大。因此，使得輪齒接觸應力大大減小，接觸強度相應提高。同時，還可以通過減小齒頂高來降低彎曲應力，從而提高彎曲強度。此外，由于齒差數(shù)小，在理論嚙合點左右，具有多對接近嚙合的小間隙齒面，輪齒受力產(chǎn)生的微小變形使得這些小間隙消失，導致這些對齒面相互接觸，因而也進入嚙合狀態(tài)：如果這種判斷符合實際情況，那么就會出現(xiàn)多對輪齒同時嚙合，顯然可以大大降低傳動沖擊，使得運轉(zhuǎn)更加平穩(wěn)、噪音更小。此外，當模數(shù)相同時，傳動能力與普通外嚙合圓柱齒輪減速器相比應當有明顯提高：在工程實際中已有應用實例證實了該判斷。

直流電機運轉(zhuǎn)震動問題解決方法
直流電機運行過程中由于震動：
首先，是否三相電壓平衡張支票，并擰緊地腳螺栓，基礎松動檢查(不會被地面松動)功率測試。
第二，釋放負荷(皮帶，齒輪等)，電源測試，以確定它是否是由不平衡負載，如果是這樣，調(diào)整負荷，與DC電機軸平行的縱向以便。
第三，直流電機維修師檢查螺絲蓋的密封性，是按對角順序系帶或不帶滑動或不含螺絲孔過大的現(xiàn)象絲，。游手好閑掃描檢查孔現(xiàn)象，如果它掃膛現(xiàn)象 ，重新封蓋，調(diào)整同心度，如果你不能調(diào)整到所需的水平，那么在良好的狀態(tài)檢查，更換或修理轉(zhuǎn)子。
第四，誠信度檢查和更換端蓋軸承，如果情況良好的軸承，天津電機維修檢查軸承和覆蓋的差距是正常的，如果差距過大，無法修理或更換。
第五，檢查定子繞組電阻和絕緣，并加以恢復。

IKO直線軸承在使用過程中出現(xiàn)故障了怎么辦？拆卸檢查固然是個好辦法，但這種方法比較費時，下面，星科五金網(wǎng)小編為您帶來不通過拆卸檢查即可識別或預測運轉(zhuǎn)中的IKO軸承是否故障的小方法。通過專人或聽音器、聽音棒進行軸承聲音識別通過聲音進行識別需要有豐富的經(jīng)驗。必須經(jīng)過充分的訓練達到能夠識別IKO軸承聲音與非軸承聲音。為此，應盡量由專人來進行這項工作。用聽音器或聽音棒貼在外殼上可清楚地聽到直線軸承的聲音。
