Detailed Description
The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the first embodiment of the invention:
referring to fig. 1, 2 and 10, the elastic shaft connecting roller of the present invention includes a roller 10 and a shaft connecting assembly 100/101, the shaft connecting assembly 100/101 is made of an elastic material, the shaft connecting assembly 100/101 includes a cylindrical shaft body 1 and a plurality of rod bodies 3, the rod bodies 3 extend outwards from the wall thickness of the shaft body 1 near the inner wall along the axial direction of the shaft body 1, and two ends of the rod body 3 may protrude out of the shaft body 1 in the axial direction. The axial center of the shaft connecting assembly 100/101 is penetrated by a mandrel 7, and the mandrel 7 is made of metal materials. The mandrel 7 may increase the strength and radial support capability of the shaft connection assembly 100/101. Of course, the mandrel 7 can also be made of a plastic material with lower cost. The roller 10 may be sleeved on the shaft body 1 or on the flange 2 as shown in fig. 10 and 11. As shown in fig. 10, the connecting member 9 to be connected is fitted over one end of the rod body 3.
Preferably, as shown in fig. 3, 4, 5, 7 and 9, the shaft connecting assemblies 100/101 are a pair, and gaps 6 are formed between the plurality of rod bodies 3 on each shaft connecting assembly 100/101, the rod body 3 of one shaft connecting assembly 100/101 is inserted into the gap 6 in the other shaft connecting assembly 100/101, and the shaft connecting assemblies 100/101 are arranged in an axisymmetric mirror image.
Preferably, as shown in fig. 6 to 10, one end of each shaft body 1 of the pair of shaft connecting assemblies 100 is provided with a radially protruding flange 2, the roller 10 is sleeved on the pair of flanges 2, or the sliding core 12 is installed between the pair of flanges 2, and the roller 10 is sleeved on the sliding core 12. The slide core 12 may be a bearing or other annular structure, so that the roller 10 may rotate around the spindle 7 and the shaft body 1 and the rod body 3. The connecting part 9 to be connected is sleeved at one end of the rod body 3, and the roller 10 drives the connecting part 9 to do linear motion when rolling, and the connecting part 9 can be a connecting part of an escalator or other similar motion mechanisms.
The end of the shaft body 1 near the connecting part 9 protrudes out of the roller 10 in the axial direction, so that a certain distance is reserved between the connecting part 9 and the roller 10, the distance between the connecting part 9 and the roller 10 is limited by the shaft body 1, the connecting part 9 cannot contact with the roller 10 when the roller 10 rolls, frictional interference cannot occur between the connecting part 9 and the roller 10, and the connecting part 9 and the roller 10 can move relatively independently. The shaft body part 1 plays a role in spacing the traditional retainer ring or the parts such as the clamp ring and the spacing ring lock ring, and the retainer ring or the parts such as the clamp ring and the spacing ring lock ring are not needed to be used additionally, so that the use parts are few and the installation is convenient.
For use situations where the requirements are not high, it may not be required to have a flange 2 structure to further reduce product costs.
Thus, the shaft connection assembly 100/101 may function as a connecting shaft. The mandrel 7 tightly supports the rod body 3, so that the rod body 3 generates tension, the elastic tension of the rod bodies 3 enables the shaft connecting assembly 100/101 and the inner wall of the roller 10 to be tightly installed together, looseness or separation between the roller 10 and the shaft connecting assembly 100/101 is not easy to occur, and the whole roller keeps a stable normal working state. By adopting the elastic component, the precision machining can be performed unlike a metal shaft, the injection molding production can be performed quickly, and the machining cost and the material cost are low. In addition, when connecting components such as the connecting components of the escalator are installed, the retainer ring or the clamping hoop and other components are not needed, the number of the using components is small, and the whole roller mechanism is convenient and quick to install.

The mandrel 7 may increase the strength and radial support capability of the shaft connection assembly 100.
Preferably, as shown in fig. 6, the protrusion 5 has an outer side surface 4 thereon, and the outer side surface 4 is parallel to an end surface 11 (see fig. 1) of the shaft body 1. This facilitates the close contact of the chain piece 8 with the protrusion 5, and the outer side 4 of the protrusion 5 is tightly clamped with one side of the chain piece 8. One end of the shaft body 1 protrudes out of the roller in the axial direction. Therefore, a certain distance is reserved between the chain sheet 8 and the roller 10, the chain sheet 8 cannot contact with the roller 10 when the roller 10 rolls, and frictional interference cannot occur between the chain sheet 8 and the roller 10.
