CLZ type gear coupling

CLZ type gear coupling is a rigid-flexible coupling consisting of an inner gear ring and a flange half coupling with outer gear.

CLZ type gear coupling has good impact bearing performance, but high requirements for tooth surface contact stress and tooth root bending fatigue strength. If we adopt structure, material and technology, then this coupling can meet the requirements of large diameter pipe rolling mills. . CLZ type gear coupling: gear coupling is a rigid-flexible coupling. The gear coupling is composed of an inner gear ring with the same number of teeth and a flange half coupling with external teeth.

特点

CLZ型齿式联轴器外齿分为直齿和鼓形齿两种齿形，所谓鼓形齿即为将外齿制成球面，球面   在齿轮轴线上，齿侧间隙较一般齿轮大，鼓形齿联轴器可允许较大的角位移（相对于直齿联轴器），可   齿的接触条件，提高传递转矩的能力，延长使用寿命。有角位移时沿齿宽的接触状态。随着我国经济的发展，大直径轧管机需求增加，其主传动使用联轴器的要求也越来越高，满足该要求的联轴器有十字式万向联轴器和大转矩鼓形齿式联轴器，其中十字式万向联轴器转矩可以达到，但承载冲击性能差、寿命短，这是一个很大的缺点；目前国内轧机用的标准联轴器无法满足要求，只达到需求转递转矩的1/2～1/3，   联轴器   制造商可以满足要求，但由于它采用专门的技术，再加上制造难度大，所以价格特别昂贵。一台轧管机需要10套左右，再加上备件外购费用很大。德国凌斯联轴器厂根据客户需求研制的各种鼓形齿联轴器已能满足国内各厂家的需求。

When CLZ type gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling needs to be Work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.Because the angular compensation of the drum gear coupling is greater than that of the straight gear coupling.
