Classification and characteristics of tyre couplings

A coupling is a mechanical component in which different driving shafts and driven shafts are firmly connected to achieve the effect of simultaneous rotation and transfer motion and torque. Today we say the classification and characteristics of tire couplings:

The main types of tyre couplings are: UL type tyre couplings, LLB type tyre couplings, LLA type tyre couplings, DL polytagonal rubber couplings, LAK saddle block elastic couplings and other types, UL type, LLB type, LLA type is more commonly used in several models. Here we will focus on these:

UL type tyre couplings specification

UL type tire coupling specifications are 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, forged steel. UL tire couplings have good damping and buffering performance, which solves the buffering effect that ordinary couplings cannot achieve.

LLB type tire couplings specification

LLB type tire coupling specifications: LLB1-13 type tire size: Ltb1-13, standard number (JBT10541-2005) original standard (JBZQ4018-85) material cast steel, cast iron and 45# round steel, other materials factory can also be customized, nominal torque :10-20000 allowable speed: 5000-1000 shaft hole diameter: 6-200mm shaft hole length: 16-382mm, Mass :0.4-340. LLB tire couplings are mainly used in metallurgical equipment, so they are also called tire couplings for metallurgical equipment. LLB tire coupling FOR metallurgical equipment is a kind of high elastic coupling, with good shock absorption buffer and superior offset compensation performance between shafts, suitable for wet, dusty, impact, vibration, positive and negative change and frequent starting working conditions, and easy to disassemble.

LLA tire couplings specification

LLA tire coupling for metallurgical equipment Specifications: LA1-11 Nominal torque: 10-20000 Allowable speed: 5000-800 Shaft hole diameter: 5-180 Shaft hole length: 14-302 Weight: 0.35-373kg Material: Cast iron steel, suitable for wet, dusty, impact, vibration, variable positive and negative rotation and frequent starting working conditions, and convenient disassembly, no lubrication, durable and reliable.

Among the three couplings, UL tire couplings are the most commonly used. The tire bodies of the three tire couplings are not the same. The tire bodies of UL and LLB tire couplings are not open, and the tire bodies of LLA tire couplings are open. Tire coupling tire body with good quality rubber, rubber inner distribution of nylon line, nylon cloth, so the tire body quality is reliable, elastic, long life and other characteristics, this is the general tire body does not have.
