Diaphragm couplings rely on metal diaphragms to transmit torque and absorb deformation caused by misalignment. There is no relative movement between parts, no friction or wear, so it does not need lubrication, which is in line with the development direction of oil-free process equipment.The gear coupling is rigid and movable...
In fact, elastic pin couplings are generally elastic sleeve pin couplings, nylon rod pin couplings, the former pin is an elastic element like rubber or polyurethane.The latter is an elastic element with a nylon rod. The two half-sections are matched with holes as large as the drill, and the nylon rod is inserted into it,...
1) Convenient maintenance and long service life. The nylon pin can be replaced by removing the baffle. 2) Compared with the gear coupling, the structure is simple, the component parts are less, the manufacturing is more convenient, and the gear processing machine tool is not needed. ...
Definition: No. 45 steel is a high-quality carbon structural steel with a carbon content of 0.42~0.50%, and 45 is the intermediate value. No. 45 steel is a high-quality carbon structural steel with low hardness and easy cutting processing. It is a common material for shaft parts. After quenching and tempering (or normalizing), better cutting...
Coupling selection principles: (1) Fixed rigid couplings can be used for short shafts with high rigidity at low speeds; (2) Movable rigid couplings can be used for long shafts with low rigidity at low speeds; ...
The advantages of diaphragm couplings: 1) No need for lubrication and routine maintenance; 2) High torsional rigidity, zero rotation; 3) No wearing parts, but can be used in various harsh working conditions; 4) If the installation is accurate, The coupling will not be damaged for life, and the life span is infinite...
