Detailed Description
Example 1
FIG. 1 is a first embodiment of the present invention provided by a universal light load friction ring sprocket.
As shown in fig. 1-8 and 18, the universal light-load friction type ring sprocket comprises a shaft 1, a first base 21, a second base 22, a wing plate 3, a first fixed screw 41, a second fixed screw 42 and a distance adjusting screw 5, wherein the first fixed screw 41 and the second fixed screw 42 are respectively provided with a first external screw section 411 and a second external screw section 421 which are opposite in rotation direction at one end, the two ends of the distance adjusting screw 5 are respectively provided with a third external screw section 51 and a fourth external screw section 52 which are opposite in rotation direction, the two ends of the wing plate 3 are respectively provided with a threaded hole 31 and a first pin hole 32, the first base 21 and the second base 22 are respectively provided with a first internal screw section 211 and a second internal screw section 221 which are opposite in rotation direction, the shaft 1 is provided with a groove 11, the distance adjusting screw 5 is arranged between the two grooves 11 on the shaft 1, the first base 21 and the second base 22 are screwed at the two ends of the distance adjusting screw 5 after being arranged on the wing plate 3, and the outer ends of the base 21 and the base 22 are respectively screwed with the first fixed screw 41 and the second fixed screw 42.
After the wing plate 3 is arranged on the first base body 21, the included angle between the wing plate 3 and the corresponding wing plate 3 on the second base body 22 is 55-95 degrees.
The first inner thread section 211 of the first base body 21 and the second inner thread section 221 of the second base body 22 are opposite in rotation direction, a first tongue-and-groove group 213 is arranged in the radial direction, an optical hole group 215 is arranged in the first tongue-and-groove group 213, a second tongue-and-groove group 214 is arranged in the axial direction, and a first pin hole group 216 is arranged in the second tongue-and-groove group 214.
The first external thread section 411 of the first fixed screw tube 41 and the second external thread section 421 of the second fixed screw tube 42 are opposite in rotation direction, the other end of the first fixed screw tube is provided with a threaded hole 422, and the external shape of the first fixed screw tube is in a polygonal shape.
The third external thread section 51 and the fourth external thread section 52 of the pitch-adjusting screw tube 5 are opposite in rotation direction. The distance-adjusting screw tube 5 is in transition fit with the shaft 1. The shaft 1 is provided with grooves 11, and the distance between the grooves 11 is slightly larger than the length of the pitch-adjusting screw tube 5.
In use, the pitch screw 5 is first mounted on the shaft 1, and then the circlip for the shaft is mounted in the groove 11 (the circlip for the shaft is not shown in the figure, and standard components such as a pin, a screw, a set screw, and the like are not shown in the figure).
The installation of the wing plate 3 on the first base 21 and the second base 22 is completed through screw connection and pin connection, and then the first base 21 and the second base 22 are screwed to the third external thread section 51 and the fourth external thread section 52 at the two ends of the pitch-adjusting screw tube 5 through the first internal thread section 211 and the first internal thread section 221.
The first fixing screw 41 and the second distance adjusting screw 42 are installed on the shaft 43, and are respectively screwed with the first internal thread section 211 and the second internal thread section 221 through the first external thread section 411 and the second external thread section 421 until the first fixing screw and the second distance adjusting screw are screwed tightly, and the annular chain wheel is installed and fixed on the shaft 1 through the screw hole group 422 by using a set screw.
When continuous conveying of the longer round-link chain is required, the conveying can be completed by means of friction force between the surface of the round-link chain and the wing plate 3 in light-load occasions such as braiding, continuous sand blasting or surface treatment. In the case of small enough load, the invention can also be used as a driving wheel. At this time, if the specification of the round-link chain to be operated is changed, the round-link chain wheel does not need to be replaced.
If the specification of the round-link chain is changed in a large range, the distance between the first base 21 and the second base 22 needs to be adjusted, and the specific implementation mode is as follows:
the set screw is first loosened, the first fixing screw 41 and the second fixing screw 42 are screwed out, and then the first base 21 and the second base 22 are fixed through the distance-adjusting fixing hole 212.
The distance adjusting screw tube 5 is rotated through the distance adjusting jack 53, the distance between the first base body 21 and the second base body 22 can be adjusted by controlling the rotation direction until the distance is adjusted properly, and then the operation is carried out reversely according to the process, so that the circular chain wheel is fixed again.
Example 2
FIG. 9 is a second embodiment of the present invention provided by a universal light load friction ring sprocket.
The difference from embodiment 1 is that the wing plate 3 is not connected by a screw, but both ends are connected by a pin, the first tongue-and-groove group 213 is not provided with the unthreaded hole group 215 but with the second pin hole group 217, and the wing plate 3 is provided with the second pin hole 33 instead of the threaded hole 31, as shown in fig. 10-12.
The disadvantage of this embodiment is that the machining positioning accuracy requirements for the first pin hole set 216 on the first base 21 and the second pin hole set 217 on the second base 22 are relatively high.
Example 3
FIG. 13 is a third embodiment of the present invention provided by a universal light load friction ring sprocket.
The difference from the two embodiments described above is that in this embodiment, the first base 21, the second base 22 and the wing plate 3 are formed by welding, and the directions of rotation of the first internal thread section 211 and the second internal thread section 221 on the first base 21 and the second base 22 after the forming are still opposite, as shown in fig. 14 and 15.
The disadvantage of this embodiment is that the deformation of the work piece after the welding formation is relatively severe. To solve this problem, an independent dedicated tooling design is required prior to the welding process. In addition, the wing plates 3 are spaced relatively little from each other, and the welding operation is difficult to implement.
Example 4
Fig. 16 and 17 are fourth embodiments provided by the present invention.
The greatest difference of this embodiment compared to the three previously described embodiments is that the first fixing coil 41 and the second fixing coil 42 are no longer designed as separate components, but are designed as one piece with the first base 21 and the second base 22, respectively.
The disadvantage of this embodiment is that after the adjustment of the distance is completed by the distance adjusting screw tube 5, the ring sprocket is directly fixed on the shaft 1 by the set screws, so that it is difficult to ensure that the screwing degree of each set screw is the same, and it is difficult to eliminate the stress generated by deformation to the greatest extent by simply leaning on the gap between the internal thread and the external thread, thereby breaking the threads.
In addition, in this embodiment, the first internal thread segment 211 and the second internal thread segment 221 are distributed in stepped holes, so that the processing difficulty of the threads is high.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the present invention.
