Description
Technical field
The utility model belongs to Pneumatic Transmission apparatus field, is specifically related to a kind of rotating cylinder utilizing driving screw.
Background technique
In existing Pneumatic Transmission equipment, air rotating cylinder is common power transmitting apparatus, mainly comprise cylinder body, piston rod and piston, piston is rotarily driven by piston rod, thus transferring power, existing air rotating cylinder, piston rod is normally directly connected with piston, but once bear larger movement load, piston rod can produce large torsion, thus cause piston rod easily to rock in radial direction generation, cause bumpy motion, simultaneously, when rocking larger, piston rod easily and inboard wall of cylinder block collide, cause rod fracture or damage, shorten its working life.
Model utility content
The utility model solve be existing rotating cylinder when bearing large movement load, piston rod easily rocks in radial direction, causes the problem of bumpy motion.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: the rotating cylinder utilizing driving screw, comprise cylinder body, driving screw and piston rod, cylinder body comprises earthen pipe, cylinder cap and cylinder head, piston rod runs through cylinder head and stretches in earthen pipe, piston is provided with in cylinder body, described driving screw is threaded cylindrical, the length of threaded cylindrical is 5cm ~ 8cm, one end of driving screw is embedded in piston, the other end connects the piston rod running through cylinder head, and be provided with thrust bearing between driving screw and piston rod, the diameter of thrust bearing is identical with the diameter of driving screw.
In this programme, piston rod rotates, drive driving screw, one end due to driving screw is embedded in piston, piston can rotate with driving screw and piston rod, when High Rotation Speed, because driving screw is threaded cylindrical, the high strength torsion produced when rotating can disperse by screw thread, thus when axial-rotation, not easily produce skew in radial direction, minimizing is rocked, and makes motion more steady, thrust bearing is provided with between driving screw and piston rod, when driving screw High Rotation Speed, preventing driving screw axially producing skew, colliding with inboard wall of cylinder block.
Further, the one end described driving screw connecting piston rod is provided with conveying mechanism, and described driving screw comprises spiral chute, and described conveying mechanism comprises several and is fixed on spherical roller in spiral chute side by side, and the diameter of described spherical roller is greater than the spiral fluted degree of depth.Due to driving screw having screw thread, when driving screw rotates, in order to not damage the screw thread on driving screw, gap can be there is between driving screw and cylinder head, but there is gap between driving screw and cylinder head, or driving screw or piston rod can be caused in radial direction easily to produce the skew of trace, there is trickle rocking, produce skew in radial direction to eliminate driving screw or piston rod further and rock, one end that driving screw connects piston rod arranges conveying mechanism, conveying mechanism comprises several and is fixed on spherical roller in spiral chute side by side, when driving screw rotates, the inwall Structure deformation of spherical roller and cylinder head, and the gap of eliminating between driving screw and cylinder head, driving screw or piston rod is avoided to produce skew in radial direction and rock, make transmission more steady.
Further, described driving screw and piston space are also provided with guiding nut, and can better prevent driving screw from offseting in radial direction, generation is rocked.
Further, described thrust bearing is thrust ball bearing, and thrust ball bearing can bear large thrust load.
