Rail is divided into as ball cage type and circulating two types.
The typical structure of ball cage type inner slide type ball line slideway is made of guide rail, sliding block, ball and cage.Sliding block has
There is installation connecting screw hole.Ball cage type inner slide type ball linear guide rail structure is simple, and bearing capacity protrudes, and ball is in cage
And contacted respectively with guide rail and slider roll, theoretically cage is run by the half way of sliding block, but is difficult to keep away due to kinematic error
Exempt from, repeatedly reciprocal rear the two is difficult to that half way is strictly kept to run, so be easy to causeing stroke failure.Although connection spiral shell is installed simultaneously
Hole is easily designed larger, but its can only horizontal application, and exist and be difficult to the return error accumulation phenomenon overcome, therefore it is perpendicular
It is restricted in the application of straight and frequent linear reciprocating motion.
Circulating inner slide type ball line slideway is generally made of guide rail, sliding block.Sliding block has two row circulating balls and one
Group installation connecting screw hole.Circulating inner slide type ball line slideway can overcome ball cage type inner slide type ball straight line well
Inadequate natural endowment of the guide rail on structural principle, but, so installation connects. at two row circulating balls of existing product in the same plane
The both sides of its center plane can only be distributed in by connecing screw hole, and so connecting screw hole can only make in the case of identical dimensions
Must be smaller, significantly limit the load application of circulating inner slide type ball line slideway.And utility model scheme proposes to put down
Row plane circulation scheme can provide larger screw hole in its center plane and make space, thus can as ball cage type that
Sample provides larger installation connection screw thread hole, and then greatly expands application range.
