LMZ-I Split Brake Wheel Type Plum Elastic Coupling(GB/T 5272-2002)

♦Description

Plum elastic coupling has the characteristics of vibration reduction, buffering, small radial size, no lubrication, and easy maintenance. Suitable for starting frequency, positive and negative rotation, medium and low speed, medium and small power transmission.Not suitable for heavy loads and frequent replacement of elastic elements.
The structure of plum elastic coupling is simple. But when the elastic element is replaced, the half coupling shall be moved axially.LMS type easily replaces the elastic element without having to move the half coupling.

♦Basic Parameter and Main Dimension

NOTE:
N.m= Norminal Torque; HA= Hardness of elastic parts; rpm= Allowable speed of rotation;
d1.d2.dz= Diameter of shaft hole; Y L= Length of shaft hole;
Model of elastic parts; kg= Mass; kg.m²= Rotational inertia
1. Mass and rotary inertia are the approximation calculated according to the recommended minimum axial hole.
2. Diameter of shaft hole with* can be used for Z-type shaft hole.
3. a.b is the code for two different materials and the hardness of elastic parts. 
4. The pre-tightening torque of the connection bolt between LMZ-I brake wheel and half coupling shall not be less than the following table:
Note: Specifications of bolt; pre-tightening torque

Allowable Amount of Compensation of Jaw CouplingNote: Model; Maximum allowable error of installation (γ= radial; α= angular); 
Maximum allowable amount of operating compensation(γ= radial; α= angular); Axial clearance(χ)
The maximum amount of operating compensation refers to the relative offset of two axes which is allowed in the working state due to manufacturing error, installation error, vibration, impact, deformation, temperature change and other comprehensive factors caused by the change of working load.
