Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.
Example (b):
a speed reduction motor connecting end cover with a speed measuring function is shown in figure 1 and comprises an end cover main body 1, an input shaft 2, a bearing 3, an oil seal piece 4 and a speed measuring sensor 5. The end cap body 1 is forged to have a shape, and is illustrated in the orientation of fig. 1, in which the front side and the rear side of the end cap body 1 are end cap surfaces, the middle portion is a neck portion, and the end cap body 1 is an annular structure having a central axis. The central axis position is an axis hole. An inner hole 23 is processed on the input shaft 2, and the inner hole 23 is directly connected with a motor.
The neck position of end cover main part 1 is provided with screw hole 11, and speed sensor 5 and screw hole 11 assembled connection, and speed sensor 5 is the shopping on the market, and it can be on end cover main part 1 relative position of adjusting from top to bottom through screw hole 11. The shaft hole position fixed connection bearing 3 of end cover main part 1, the inner circle fixed connection input shaft 2 of bearing 3, bearing 3 and input shaft 2 between set up through oil seal 4 sealed. The threaded hole 11 is identical to the shaft hole of the end cap body 1. The shaft hole position of end cover main part 1 is provided with spacing platform 12, and bearing 3 supports and leans on spacing platform 12.
The input shaft 2 is provided with a raised collar 21, the number of the bearings 3 is two, and the two bearings 3 are distributed on two sides of the collar 21. The collar 21 described above forms a rectangular tooth structure. The collar 21 is positioned directly opposite the location of the threaded hole 11. The collar 21 comprises a number of projections 211 evenly distributed circumferentially on the input shaft 2, with recesses 212 being formed between adjacent projections 211.
The threaded hole 11 is provided with the position and just faces two on same diameter line, and the speed sensor 5 sets up two, and the lug 211 is provided with eight.
