Machining the ball screw linear bearing box unit
- PRODUCT DETAIL
9) Tooth angle β—the angle between the side of the thread profile and the vertical plane of the thread axis. The main geometric dimensions of various threads of symmetrical teeth (except for rectangular threads) can be found in the relevant standards. - The nominal size is the outer diameter of the thread and the pipe thread is approximately equal to the inner diameter of the pipe.
The self-locking condition of the spiral pair is: The thread lift angle is less than or equal to the equivalent friction angle of the screw pair.
The transmission efficiency of the screw pair is: The ratio of effective work to input work when the nut is rotated one revolution.
Overcoming the circumferential force required for the uniform increase of the axial force Q
- For the outer wheel separation type and the inner wheel rotation.
- For use where it is necessary to rotate the inner wheel.
