Definition and features :
1 G stand for single joint ,GD stand for double joint .
2 finished product tolerance is H7 .we usually can make differnt kinds of hole type ,such as keyway, hexagonal hole ,square hole .
3 G,GD is slieding bearing ,no need maintain ,max speed 1000roll/min.
4 GZ or GDZ means needle bearing ,also no need maintain ,max speed will reach to 4000 roll/ min.
5 The maximum operate angle of each joint is 45degree .
Some tips for choosing the DG precision coupling with drive shaft coupling :
To ensure angular velocity between the driving and driven shaft under synchronous rotation,should choose double cross shaft universal joint or two single cross shaft universal joint connect together ,also need meet the following 3 conditions:
a) the angle of intermediate shaft between driving and driven shaft should equal ,
b) The symmetry surfaces of the two intermediate shaft ends are in the same plane ,
c)When the intermediate shaft and the driven shaft in the same plane to install the single shaft universal joint, the angle of two shaft is different ,can not keep synchronous operation,thus will change with the angle .
