摘  要
CPM下肢康復(fù)器又稱持續(xù)被活動康復(fù)器，它是用來幫助膝關(guān)節(jié)置換手術(shù)的病人、下肢康復(fù)期患者恢復(fù)其關(guān)節(jié)功能的一種機(jī)器。
本文闡述了CPM康復(fù)器的特點和應(yīng)用。設(shè)計了以端部關(guān)節(jié)驅(qū)動的CPM康復(fù)器，該機(jī)通過電動機(jī)輸出動力，帶動滾珠絲杠的旋轉(zhuǎn)來驅(qū)動。文中對主要的受力桿件進(jìn)行了受力分析和計算。校核了電機(jī)功率、軸承的壽命和銷。繪制總裝配圖、伸縮桿、軸等工程圖樣。
該CPM康復(fù)器結(jié)構(gòu)簡單、緊湊，傳動平穩(wěn)。

Development of CPM exerciser for lower limbs
Abstract
 Rehabilitation of lower limb CPM devices are also known as the continuing rehabilitation activities, and it is used to help patients with knee joint replacement surgery, patients with lower limb rehabilitation to restore the joint function of a machine.
 In this paper, the characteristics of CPM rehabilitation devices and applications. Designed to end joint rehabilitation CPM rehabilitation, and the plane through the motor output power, the rotation of ball screw drive to drive. In this paper, the main bar by the force conducted a stress analysis and calculation. Check the motor power, the life of bearings and sales. The total assembly drawing, telescopic rod, shaft, such as engineering drawings.
 Rehabilitation of the CPM structure is simple, compact, smooth drive.
