Flexible Couplings are one of the major types of couplings. They find use to connect two shafts, end-to-end in the same line to transmit power that is torque from one shaft to another, thereby causing both to rotate in unison, at the same rpm.

The purpose of a Elastic Coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch. Actual misalignment, expressed in coupling terms, is angular in nature and expressed in angular units, that is, degrees. How much misalignment is a function of the coupling type and installation. An installation variable is the equipment movement due to the temperature changes taking place in the machines as they go from the non-operating state to operation. Some angular values will be used in the discussion of the various types, but, again, these are for reference only. Each application must be reviewed using the type of coupling selected and the specific design proposed by the vendor.

The tyre coupling adopts tyre body-shaped rubber elements, which are connected with two semi-couplings through bolts to realize torque transmission and displacement compensation. Tyre coupling has high elastic performance, small torsional rigidity, strong damping capacity, large axial compensation capacity, and good damping performance.

The flexible tyre coupling is one of the easiest coupling to install and maintain. Unlike many other couplings, the elastic tyre coupling takes only minutes for replacement as you only need to replace the tyre element! This replacement requires neither special tools nor skilled labour. This simple time-saving installation also ensures that motor and machine remain undisturbed whilst tyre is changed.

• LLB Elastic Tyre Coupling
• LLA Elastic Tyre Coupling

  The LLA Tyre Coupling uses two semi-couplings to connect both sides of the elastic tyre body through internal pressing plates and bolts, making it easy to replace the elastic tyre body.
• UL Elastic Tyre Coupling

  UL Tyre Coupling adopts the structure of vulcanizing and bonding the tyre body with the metal connecting plate with threaded holes, which is then directly connected to the two semi-couplings by bolts for torque transmission and other displacement compensation.
