DL polygonal rubber coupling
DL polygonal rubber couplings are used in chemical, shipbuilding, automotive, engineering machinery, light industrial machinery, agricultural machinery and other industries, such as the connection of diesel engines and water pump shafts.
Polygonal rubber coupling is made of rubber material, made into a circular 6-corner (or octagonal) elastic piece, in each place is embedded with rubber after vulcanization and bonded to the sleeve, through the The 8 (or 6) bolts of the sleeve are alternately connected with the half coupling flanges on the main and driven ends.The polygonal rubber coupling has a simple structure, does not require lubrication, and is easy to assemble and disassemble. It can relax the torsional vibration and impact load of the drive shaft, prevent the drive shaft from resonating and compensate for the relative deviation of the two axes. It is suitable for medium torque 8 -50N.M light industry, engineering machinery, mining machinery and other industries, suitable for working environment with dust and moisture, working temperature is -8000-30℃, used for the connection of vibrating screens.
Reference for the basic parameters of DL polygonal rubber coupling:
The relative allowable radial displacement of the two shafts is 1-2mm
Allowable axial displacement is 4-10mm
Allowable angular displacement 5-2°
The twisting angle is 5-12°
Shaft diameter 25-160mm
Coupling outer diameter s up to 96-520mm
Allowable torque 50-8200N.m
The instantaneous impact torque is 2.5 times the allowable torque, and the allowable speed is 10000-1500r/min

The characteristics and maintenance methods of gear couplingGear 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 shaft sleeve and end cover. Generally, small-sized gear coupling end cover and inner gear ring can be integrated. ...The structure and application range of slider couplingThe slider coupling is also known as the metal cross slider coupling. Its slider is in the shape of a ring and is made of steel or alloy. The cross slider coupling is suitable for transmissions with low speed and large transmission torque.The slider coupling is composed of two shaft sleeves and a slider. ...
