本聯(lián)軸器適用于聯(lián)接水平兩同軸線，并具有一定角向位移的傳動軸系。傳遞公稱轉矩為0.8～32000KN.m,工作環(huán)境溫度－20～＋８０℃
鼓形齒式聯(lián)軸器的特點
●齒式聯(lián)軸器是由齒數(shù)相同的內(nèi)齒圈和帶外齒的凸緣半聯(lián)軸器等零件組成。外齒分為直齒和鼓形齒兩種齒形，所謂鼓形齒即為將外齒制成球面，球面中心在齒輪軸線上，齒側間隙較一般齒輪大，鼓形齒聯(lián)軸器可允許較大的角位移（相對于直齒聯(lián)軸器），可改善齒的接觸條件，提高傳遞轉矩的能力，延長使用壽命。有角位移時沿齒寬的接觸狀態(tài)。
●齒式聯(lián)軸器在工作時，兩軸產(chǎn)生相對角位移，內(nèi)外齒的齒面周期性作軸向相對滑動，必然形成齒面磨損和功率消耗，因此，齒式聯(lián)軸器需在有良好和密封的狀態(tài)下工作。齒式聯(lián)軸器徑向尺寸小，承載能力大，常用于低速重載工況條件的軸系傳動，高精度并經(jīng)動平衡的齒式聯(lián)軸器可用于高速傳動，如燃汽輪機的軸系傳動。由于鼓形齒式聯(lián)軸器角向補償大于直齒式聯(lián)軸器，國內(nèi)外均廣泛采用鼓形齒式聯(lián)軸器，直齒式聯(lián)軸器屬于被淘汰的產(chǎn)品，選用者應盡量不選用。
●Ｉ型－密封端為分離型，齒間距較大，可以允許較大的徑向位移，可與Ｙ、Ｊ１、Ｚ１型軸伸聯(lián)接。
Ⅱ型－密封端為整體型，齒間距小，相對允許徑向位移小，結構緊湊，轉動慣量小，可與Ｙ、Ｊ１型軸伸聯(lián)接。
This coupling is applicable to the two coaxial lines of the connection level and the transmission shafting with a certain angular displacement. Transfer the nominal torque 0.8 ~ 32000 kn. M, working environment temperature - 20 ~ + 80 ℃
Features of drum gear coupling
The gear coupling is composed of the same inner ring and the flange half coupling of the outer tooth. Divided into straight teeth and drum tooth outside two kinds of tooth shape, tooth is the so-called drum will made spherical outer teeth, spherical center on the gear axis, backlash is generally large gear, drum gear couplings allows a larger angular displacement (as opposed to straight tooth coupling), can improve the tooth contact conditions, improve the ability to transfer torque, prolong service life. The contact state along the tooth width in angular displacement.
Low coupling at work, two relative angular displacement of the shaft of the internal and external gear tooth surface of periodic axial relative sliding, inevitable formation of tooth surface wear and power consumption, therefore, the coupling should be in good and sealing state work. Type coupling radial size is small, large carrying capacity, often used for shaft transmission of working condition of low speed and heavy loading, high precision and the dynamic balance of coupling can be used for high-speed transmission, such as gas turbine shaft transmission. Because the drum type coupling Angle is greater than the direct coupling to the compensation, both at home and abroad widely used drum type coupling, straight type coupling are eliminated products, choose those should not choose as far as possible.
The type I - sealing end is the separation type, the tooth spacing is larger, can allow larger radial displacement, can be connected with Y, J1, Z1.
Ⅱ - sealed end to overall, tooth spacing is small, relative to allow the radial displacement is small, compact structure, and the moment of inertia is small, can be connected to Y, J1 type shaft extension.
