Description
Technical field
The utility model relates to field of textile machinery, specifically a kind of loom back rest mounting structure.
Background technology
The loom back rest is the important spare part of rapier loom, and for supporting and carrying fabric, existing back rest mounting structure is unreasonable, easily causes stand-off to damage when supporting and carry heavily fabric, increases maintenance cost, and impact is produced.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and a kind of loom back rest mounting structure of rational in infrastructure, long service life is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A loom back rest mounting structure, comprises roller and the stand-off of central shaft, bearing, hollow, and the two ends of described central shaft are fixed on stand-off; The inner side, two ends of central shaft is respectively equipped with a bearing, and the inner ring of bearing is connected with central shaft interference fit; Described roller is set in the outside of central shaft, and bearing outer ring is connected with roller interference fit, and the internal diameter of described roller is greater than the maximum outside diameter of central shaft; Described central shaft, bearing and roller are coaxial.The beneficial effect of the technical program is: rationally, simply, long service life, has solved the flimsy problem of stand-off to back beam structure, has reduced maintenance cost.
As preferably, described stand-off comprises two clamping parts, and one end of two clamping parts is hinged, and other end bolt connects, and two clamping parts are provided with respectively symmetrical semi-circular recesses, and the end of described central shaft is placed in groove and is fixedly clamped by two clamping parts.Adopt the technical program, stand-off is fixed center axis firmly not only, and is convenient to dismounting.
As preferably, inner side, described central shaft two ends is 30-35 millimeter with the diameter of bearing cone Fit.Adopt the technical program, can guarantee that central shaft is difficult for bending, provide support the support force of heavily fabric, also can not cause because central shaft is overweight stand-off to damage.
As preferably, described roller surface has chromium coating.Chromium matter is extremely hard, corrosion-resistant, in roller surface chromium plating, can increase the ABRASION RESISTANCE of roller and prevent roller corrosion.
As preferably, described roller wall thickness is 8-10 millimeter.Adopt the technical program, can guarantee that roller is not fragile, provide support the support force of heavily fabric.
As preferably, the material of described central shaft and roller is 45# steel.The anti-folding of 45# steel, anti-bending strength are good, and the central shaft and the roller that adopt 45# steel to do can bear the pressure that heavily fabric causes, and are not easy to damage.

Fig. 2 is the right view of the utility model loom back rest mounting structure.
In figure: 1, central shaft, 2, bearing, 3, roller, 4, stand-off, 5, clamping part, 6, bolt.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, with reference to the accompanying drawings the utility model specific embodiment is described further below.
As shown in Figure 1 and Figure 2, a kind of loom back rest mounting structure, comprises roller 3 and the stand-off 4 of central shaft 1, bearing 2, hollow, and the inner side, two ends of described central shaft 1 is respectively equipped with a bearing 2, and the inner ring of bearing 2 is connected with central shaft 1 interference fit; Described roller 3 is set in the outside of central shaft 1, and bearing 2 outer rings are connected with roller 3 interference fit, and the internal diameter of roller 3 is greater than the maximum outside diameter of central shaft 1; Described central shaft 1, bearing 2 and roller 3 are coaxial; Described stand-off 4 comprises that one end of 5, two clamping parts 5 of two clamping parts is hinged, and other end bolt connects, and two clamping parts 5 are respectively equipped with symmetrical semi-circular recesses, and the end of described central shaft 1 is placed in groove and is fixedly clamped by two clamping parts 5; Stand-off 4 is fixed in frame; Described central shaft 1 inner side, two ends is 30-35 millimeter with the diameter of bearing 2 inner ring Fits; Described roller surface has chromium coating; Described roller 3 wall thickness are 8-10 millimeter; The material of described central shaft 1 and roller 3 is 45# steel.
By reference to the accompanying drawings embodiment of the present utility model is described in detail above, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
