Recently, many see users react questions such as: linear module of ball screw of the gap is too big?
。
Many users have encountered such a problem.
Therefore, small make up specially compiled for a linear gear coupling of ball screw the cause of the gap is too big and preventive measure, hoping to help the masses of users.
a, bearing improper selection
with ball screw in linear module must usually oblique bearing, especially for high pressure Angle design bearing the better choice; When the ball screw axial load under normal deep groove ball bearing can produce among a certain amount of axial gap, so the deep groove ball bearing does not apply.
2, bearing installed improperly
1, if the bearing installed on the ball screw in linear gear coupling and the joint is not indeed, in the case of carry axial load can lead to back lash production, this situation may be due to the screw shoulder too long or too short.
2, bearing bearing on surface and the lock nut V teeth axis perpendicularity, parallelism or two corresponding to the direction of the swinging nut surface, can cause bearing tilt; So screw locking nut to shoulder V teeth and bearings bearing on surface must be processed at the same time, to ensure the verticality, if processing in grinding way better.
3, without preloading or insufficient preloading
no linear module of ball screw preloading vertically, nut you turn down due to the weight of itself; Without preloading of the screw will be a gap exists, therefore can only be used for small resistance of the machine operation, but the main concern is positioning accuracy is not required. To determine the correct amount of preloading on different applications, and adjusted the preloading prior to shipment;
4, nut or insufficient bearing rigidity
if the nut or insufficient bearing stiffness, due to the weight of the element itself or the load of the machine can make the production of deflection.
5, nut or improper bearing assembly
1, due to vibration or not fix the quotas for marketing makes the strengthening component loose. To replace the spring solid lock pin to achieve the purpose of positioning;
2, due to fixed screw is too long or nut screw hole is too shallow prevented nut fixed screw locking;
3, due to vibration or lack of spring washer so nut screw loose.
6, the surface of the brackets parallelism or flatness tolerance
whether combining components surface is grinding or shovel flower, as long as its parallelism or flatness beyond the tolerance range, bed movement when the position of repeat precision will be poor; So a machine, usually between the brackets and machine body to achieve the purpose of adjusting shims.
7, the torsional displacement is too large,
1, improper material selection;
2, improper heat treatment, hardening layer is too thin, hardness distribution or material too soft steel ball, nut, screw the standard hardness is HRC62 ~ 66 respectively, HRC58-62, HRC56-62.
8, planetary gear motor and ball screw with improper
1, coupling hardness, combined with weak or itself between screw and planetary gear motor causes slip;
2, if not suitable for the gear drive or drive is not rigid body structure, can be used in the belt to drive in order to prevent the slide;
3, the key is loose, or key, slotting, any improper collocation, between the wheels are made between these components produce clearance;
as long as find ball screw linear module the cause of the gap is too big, and take the corresponding measure, then the problem can be solved soon. Of course in linear module of ball screw installed correctly when it is very important also to maintain the peace.
