GL type roller chain coupling

GL-type roller chain coupling AUTOCAD renderings (GB6069-2002 instead of GB6069-86) Features: The chain coupling uses a common chain and meshes with two parallel sprockets with the same number of teeth at the same time. Chain couplings of different structural types The main difference between the shafts is the use of different chains, the common ones are double-row roller chain couplings, single-row roller chain couplings, toothed chain couplings, nylon chain couplings, etc.The performance of double-row roller chain couplings is better than that of other structural types of couplings. It is widely used and our country has also formulated it as a standard.

Example 1: GL7 type roller coupling

主动端：J1型孔，B型键槽 d1＝45mm,L1＝84mm

从动端：J1型孔，B1型键槽 d2＝50mm ，L1＝84mm 

GL7 coupling

J1B45×84/J1B150×84＝GB6069-85

Example 2: GL3 type roller chain shaft with cover

主动端：J1型孔，B型键槽 d1＝25mm,L1＝44mm

从动端：J1型孔，B1型键槽 d2＝25mm ，L1＝44mm

Note:

1. When there is a cover, add "F" after the model number, for example, GL5 type coupling, when there is a cover, change to GL5F.

2. The coupling mass and moment of inertia in the table are approximate values.

3、联轴器的轴孔和键槽型式及尺寸见表4-2-3和表4-2-5。

4. The lubrication of the coupling has a significant impact on the performance. It should be lubricated regardless of whether there is an outer cover or not.

5. Refer to Table 4-2-10 for the allowable compensation amount of the coupling.
