One perpendicular clip-connecting rod, the end face of the fastening bolt are provided with and the matched radian of semiaxis.The structure can clamp half
Axis, shares scroll chuck stress, greatly extends the service life of scroll chuck, has saved cost.But there is also such as above scheme
Lower shortcoming:
1, semiaxis is compressed using fastening bolt, each bolt must be screwed into identical length, and no person will lead to half
The radial force of axis is uneven and generates bending, thus generates biggish mismachining tolerance, but is unable to ensure each bolt and is screwed into
Equal length, therefore above scheme will lead to biggish mismachining tolerance.
2, it is connect using a clip-connecting rod with scroll chuck, bonding strength is lower, and reinforcement effect is smaller.
