Description

  The present invention relates to a running support plate for a running machine provided on a base of a running machine.

  As shown in FIG. 6, a normal running machine has a machine base 1 having both side frames (not shown) arranged at intervals in the left and right directions, and a space between both side frames of the machine base 1. The front and rear shaft rods 3 and 3 that are pivotally supported and connected so that one of the heads can be driven and rotated by the motor 5 as a main shaft, and the front and rear shaft rods 2 3 and 3, and can be circulated between the front and rear shaft rods 3 and 3 by the rotation of the shaft rod 3 as the main shaft, and the upper surface 41 is used as a traveling surface of the runner. An endless belt 4 and a substantially rectangular traveling support plate 2 provided in the both side frames between the front and rear shaft rods 3 and 3 and supporting the upper surface 41 of the endless belt 4 from below are provided. .

  However, as shown in the figure, in the conventional running machine, since the travel support plate 2 supports the endless belt 4 in a substantially full surface contact state, the travel support plate is rotated while the endless belt 4 is rotating. 2 and the endless belt 4 have a large contact resistance, and the amount of heat generated by the contact resistance is considerably large. Therefore, the endless belt 4 cannot be smoothly rotated but is extremely distant from the traveling support plate 2. There is a problem that wear is rapid due to mutual friction. Further, although the lubricating oil is usually applied between the traveling support plate 2 and the endless belt 4, the lubricating oil will soon disappear due to the surface contact and the excessive mutual friction. There is also a problem that.

  The present invention has been made in view of the above problems, and can smoothly rotate an endless belt to suppress wear thereof, and can also reduce consumption of lubricating oil with the endless belt. An object is to provide a running support plate for a running machine.

  In order to achieve the above object, the inventor only needs to reduce the contact resistance between the endless belt and the travel support plate, that is, to reduce the contact area between the endless belt and the travel support plate as much as possible. On the basis of the idea, a running support plate for a running machine provided on a base of a running machine so as to support the upper surface of an endless belt whose surface is a running surface of a runner by being rotated, the endless A running support plate for a running machine is provided, wherein a support surface that supports the upper surface of the belt from below is in contact with the endless belt.

  Further, in the above configuration, the support surface has a plurality of protrusions or depressions scattered on a plane, and further, a plurality of depressions or protrusions are scattered on a plane without the plurality of protrusions or depressions. preferable.

  With the above configuration, the running support plate for a running machine according to the present invention is not in the state of almost all surface contact in the past, but the endless belt in a state in which the support surface supporting the upper surface of the endless belt from below is in a plurality of uneven contact. Since it supports, since the contact area between both is far smaller than before, the contact resistance between both is small, an endless belt can be rotated smoothly and the wear can be suppressed.

  Further, since the support surface and the endless belt are in an uneven contact, the lubricating oil is well retained and the effect of lubrication can be achieved for a long time.

  Hereinafter, embodiments of a running support plate for a running machine of the present invention will be described with reference to the drawings.

  FIG. 1 is a partially cut perspective view of a running machine to which a first embodiment of a running support plate for a running machine of the present invention is attached. FIG. 2 is a cross-sectional view of a main part of the running machine. FIG. 3 is an enlarged view showing a contact relationship between the running support plate for the running machine and the endless belt in FIG. 2.

  First, the features of the present invention will be described using the first embodiment shown in FIGS.

  In general, as shown in FIGS. 1 and 2, this running machine is not significantly different from the conventional one, but the running machine travel support plate 6 of the present invention attached thereto is also driven to rotate so that the surface 71 moves on the surface 71. The running machine base 10 is provided so as to support the upper surface of the endless belt 7, which is the running surface, from below.

  When the drawing is seen in more detail, the support surface 61 for supporting the upper surface of the endless belt 7 from the bottom of the traveling support plate 6 for the running machine of the present invention is in contact with the endless belt 7 in a plurality of irregularities.

  In the first embodiment, with respect to the actual structure related to the plurality of uneven contacts, the support surface 61 is mainly formed so that the plurality of protrusions 611, 611,. The plurality of protrusions 611, 611,... Are hemispheres each having a height of 1 mm or less and a diameter of less than 5 mm.

  FIG. 4 is a partial cross-sectional view showing a contact relationship between a modified example of the running support plate for the running machine of the first embodiment and the endless belt. In this modified example, in addition to the structure of the running support plate 6 for the running machine of the first embodiment, a plurality of depressions 612, 612,... Are scattered on a plane of the support surface 61 where the plurality of protrusions 611, 611,. is doing.

  FIG. 5 is a partial cross-sectional view showing a contact relationship between a running support plate for a running machine and an endless belt according to the second embodiment. The support surface 61A of the second embodiment has a plurality of depressions 613, 613,... Scattered on the plane, and a plurality of depressions 613, 613,. The projections 614, 614, which are hemispheres are scattered.

  Due to the uneven contact relationship as described above, the running support plate for a running machine of the present invention supports the endless belt with a much smaller contact area than the conventional one, and can also hold the lubricating oil well. It can rotate smoothly and wear is greatly suppressed.

  The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment and is not construed in a narrow sense. For example, if the object of the present invention can be achieved, the plurality of protrusions Alternatively, any number, position, shape, and size of the depressions may be appropriately arranged. That is, various modifications and changes are possible within the scope of the idea of the present invention.

  As described above in detail in the embodiment, according to the running support plate for a running machine of the present invention, it is possible to smoothly rotate the endless belt to suppress its wear, and to lubricate the endless belt. Oil consumption can also be reduced.
