Primary Selection And Adjustment Model Of Coupling

Date:Jan 02, 2019

Primary model

According to the calculated torque Tc, the approximate nominal torque Tn can be selected from the standard series, and Tn ≥ Tc should be satisfied during the selection. Initially select the coupling model (specification), from the standard can be found the allowable speed of the coupling [n] and the maximum radial dimension D, axial dimension L0, to meet the coupling speed n ≤ [n] .

Adjustment model 

The pre-selected coupling coupling dimensions, ie the shaft hole diameter d and the shaft hole length L, shall comply with the requirements of the main and driven end shaft diameters, otherwise the coupling specifications shall be adjusted according to the shaft diameter d. It is common for the main and driven end shaft diameters to be different. When the torque and speed are the same and the main and driven end shaft diameters are different, the coupling type should be selected according to the large shaft diameter. In the newly designed transmission system, seven types of shaft holes that meet the requirements of GB/T3852 should be selected. It is recommended to use the J1 type shaft hole type to improve versatility and interchangeability. The length of the shaft hole is in accordance with the product standard of the coupling. .
