Plum coupling, diaphragm coupling, elastic pin coupling, drum gear coupling_Hangzhou Hengli Transmission Machinery Co., Ltd.

Gear coupling is a kind of removable rigid coupling.It uses internal and external tooth meshing to realize the torque rotation and movement transmission between the two halves of the coupling. It is suitable for the transmission shaft system connecting two concentric shafts, and has the performance of relatively compensating the relative displacement of the two shafts.Its structure is shown in Figure XNUMX. It is composed of main parts such as inner gear ring, gear sleeve and end cover. Generally, small-sized gear coupling end cover and inner gear ring can be integrated.

The main types of tire couplings are: UL tire coupling, LLB tire coupling, LLA tire coupling, DL polygonal rubber coupling, LAK saddle block elastic coupling, etc. UL type, LLB type, and LLA type are several models that are more commonly used.Below we will focus on the characteristics of these couplings: UL tire coupling specifications are mainly UL1-18, nominal torque: 10-25000, allowable speed: 5000-800, shaft hole diameter: 11 -180mm, shaft hole length: 22-302mm, weight: 0.7-818, material: 45# round steel, cast steel,

Diaphragm couplings are often used in servo systems. Diaphragms have good torque rigidity, but are slightly inferior to bellows couplings.

Diaphragm coupling is a coupling that uses thin springs to connect with the two halves of the coupling by bolts or other coupling methods to realize the elastic coupling of the two shafts.

Diaphragm couplings are suitable for shafting transmission in high temperature, high speed, and corrosive environment, and are widely used for shafting transmission of various mechanical devices, such as water pumps, high-speed power transmission systems for ships, etc.
