Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As depicted in figs. 1 and 2, the adjustable spacing device of straightener back up roll described in the utility model, comprises U-shaped erection support 1, support seat cover 2, bearing pin 3, running roller 4; Described U-shaped erection support 1 has bearing pin mounting groove, and the centre position of described U-shaped erection support 1 is provided with the mounting groove 11 mated with running roller 4; Described bearing pin 3 is arranged in bearing pin mounting groove, is compressed by support seat cover 2, and radial fixing; Described running roller 4 is arranged on bearing pin 3, and is positioned at the mounting groove 11 in U-shaped erection support 1 centre position;
Described running roller 4 has inner ring 41; On described inner ring 41 end face and U-shaped erection support 1 mounting groove 11 inwall between be provided with the length-adjustable spacing adjusting device of spacing; Described inner ring 41 is held out against by spacing adjusting device.
Described U-shaped erection support 1 Main Function plays to support bearing pin 3, can realize being connected with smoothing roll roll stand simultaneously.Bearing pin 3 is pressed on U-shaped erection support 1 by described support seat cover 2.Because described bearing pin 3 is arranged in bearing pin mounting groove, compressed by support seat cover 2, and radial fixing; Therefore avoid in the process that bearing pin 3 rotates at running roller 4 and rotate, thus cause the wearing and tearing between bearing pin 3 and U-shaped erection support 1.Concrete can prevent bearing pin 3 from rotating by milling plane of orientation on bearing pin 3.
The length-adjustable spacing adjusting device of spacing is provided with between inwall due to mounting groove 11 on described inner ring 41 end face and U-shaped erection support 1; Described inner ring 41 is held out against by spacing adjusting device.Therefore after between inwall spacing adjusting device being installed to inner ring 41 end face and mounting groove 11, can by regulating spacing length thus making spacing adjusting device hold out against inner ring.Avoid the problem that traditional distance collar relies on machining accuracy, means such as assembling reconditioning etc. cannot hold out against inner ring, extend bearing service life, shorten the set-up time, improve production efficiency, reduce production cost.Described spacing length is the length of spacing between spacing adjusting device location inner ring 41 end face and mounting groove 11 inwall.
The adjustable spacing device of straightener back up roll described in the utility model in sum, is convenient to regulate, easy for installation, can reduce repeatedly to assemble, measure and set-up time of repair, enhances productivity, reduces production cost.Can increase the service life simultaneously.
Described spacing adjusting device can adopt implemented in many forms, such as adopts spring, all arranges back-up ring at the two ends of spring, and back-up ring is close to the inwall of inner ring 41 end face and mounting groove 11 respectively, realizes automatically regulating by the restoring force of spring.Adopt this kind of spacing adjusting device less stable, spring easily lost efficacy.
In order to improve the stability of structure, be convenient to regulate, as shown in Figure 1, preferred described spacing adjusting device comprises described inner ring 5, outer shroud 6 simultaneously; Described inner ring 5 is sleeved on bearing pin 3, and radial fixing; Described inner ring 5 outer ring is provided with screw thread, and the inner ring of described outer shroud 6 is provided with screw thread, the inner ring of described outer shroud 6 and the outer ring threaded engagement of inner ring 5, and screw thread self-locking; One end of described inner ring 5 and the end face of inner ring 41 are close to, on one end of described outer shroud 6 and U-shaped erection support 1, the inwall of mounting groove 11 is close to, or described inner ring 5 is close to the inwall of mounting groove 11 on U-shaped erection support 1, described outer shroud 6 is close to the end face of inner ring 41.
In the process regulating spacing length, only need turn outer shroud 6, change the relative position between inner ring 5 and outer shroud 6 by rotation outer shroud 6, thus change the length of whole distance collar, reach the object holding out against inner ring.Owing to passing through self-locking thread engagement between outer shroud 6 and inner ring 5, therefore inner ring 5 and outer shroud 6 can not relatively rotate when being subject to responsive to axial force; Thus spacing length can not be changed.Therefore this Stability Analysis of Structures, is convenient to regulate simultaneously.
Described inner ring 5 radial direction is fixing, thus inner ring 5 can not be rotated, concrete, is provided with positioning key 7 between the inner ring of described inner ring 5 and bearing pin 4; Described inner ring 5 is fixing by positioning key 7 radial direction.
For the ease of regulating position length, further, the outer ring of described outer shroud 6 is provided with tighten outer shroud 6 turn structure.
Concrete, the structure that turns that the outer ring of described outer shroud 6 is arranged is fabrication hole.By inserting driving lever in fabrication hole, move the adjustment that driving lever can realize spacing adjusting device spacing length.
The described another kind of form turning structure is, the outer ring of described outer shroud 6 is polygon.Outer ring due to outer shroud 6 is polygon, therefore outer shroud 6 can be made to rotate by spanner or pin cone, thus be convenient to regulate.
