Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, an elastic coupling of a split disc pin according to an embodiment of the present utility model includes: iron core 1, pin 2 and flange 3. The pin 2 is mounted on the iron core 1, and the iron core 1 and the pin 2 are assembled in the flange 3.
The iron core 1 comprises a cylindrical part 101 and wing parts 102; the number of the wing parts 102 is three, and the wing parts 102 are fixedly arranged on the side wall of the cylindrical part 101, and preferably the three wing parts 102 are evenly distributed on the side wall of the cylindrical part 101. The connection between the cylindrical portion 101 and the wing portion 102 may be welded, or the cylindrical portion 101 and the wing portion 102 may be integrally cast.
The pin 2 is provided with a through hole 201 for sleeving the wing 102; the lower contact surface 202 of the pin 2 is arc-shaped and is adapted to the side wall 103 of the cylindrical portion 101.
The flange 3 includes a limit portion 301 and a mounting surface 302. The flange 3 is a cast aluminum flange for being mounted on an engine flywheel, a mounting surface 302 of the flange 3 is provided with a region to be processed for forming bolt mounting holes and/or mounting rabbets, and the preferred region to be processed is the mounting surface 302.
And (2) mounting: the wing parts 102 of the iron core 1 are penetrated into the through holes 201, so that the three wing parts 102 of the iron core 1 are respectively sleeved with the pins 2, and then the iron core 1 is placed in the limiting part 301, and the installation is completed. The core 1 is used for being connected with various driven end shafts, such as a hydraulic pump shaft or a compressor shaft, etc., to transmit the load of an engine.
The existing disc type coupling flange main body is made of nylon, and the coupling main body is formed by injection molding of a die. The shape and the size of the coupler are fixed and cannot be flexibly adjusted. When the bolt mounting hole of the engine flywheel on the coupler is produced and processed, the nylon main body material has soft texture, and a metal sleeve is also required to be nested for bearing the extrusion during the screwing of the bolt. Further, the mounting size of the coupling is fixed and cannot be changed. In order to match different engine flywheel interfaces, various types of disc couplings are produced. Therefore, the problems of poor universality, various varieties, poor production adjustment flexibility and the like of the disc coupler in the prior art are formed.
The flange 3 is selected as a cast aluminum flange. By adding the area to be machined, compared with a traditional disc coupling. According to different engine interfaces, only bolt mounting holes and/or mounting rabbets are processed in the area to be processed, and the flywheel interfaces of the corresponding engines can be matched.
In the prior art, the disk coupler has the problem of loud noise. Noise is mainly generated due to the fact that abrasion or machining precision is used, and the shafting is deviated in centering. In order to reduce the generation of noise, the utility model is further improved:
the pin 2, the iron core 1 and the flange 3 are provided with gaps; the pin 2 is made of nylon. The nylon material has good pressure resistance and wear resistance. Through adopting flange 3 cooperation nylon material's of cast aluminum material pin 2, make transmission load increase, life is longer. The split pin 2 has elasticity, can realize the effects of compensating shafting centering deviation and damping and noise reduction of the coupler, and is convenient for the use and installation of the disc coupler. The pin 2 is mainly stressed by the compressive stress of the flange 3 during operation, while nylon has good pressure resistance and wear resistance, so that the nylon can bear large load and has long service life.
As shown in fig. 1-3, the specific arrangement of the slits is as follows:
the slits comprise a first slit 4, a second slit 5, a third slit 6 and a fourth slit 7;
the first gap 4 is the gap between the side wall 103 of the wing 102 and the inner side wall 203 of the pin;

the third gap 6 is a gap between the top end 205 of the pin and the first inner top end 304 of the limit part;
the fourth gap 7 is a gap between the side wall 103 of the cylindrical portion and the second inner top end 305 of the limiting portion.
The second inner top end 305 of the limiting portion is concave arc-shaped.
The maximum gap length b of the third gap 6 and the maximum gap length b of the fourth gap 7 are 1:1.
Through foretell gap setting for the overall noise is littleer stability stronger.
