Optionally, the first connecting plate 121 and the second connecting plate 122 are fixed integrally by welding, and it can be understood that, in other embodiments, the first connecting plate 121 and the second connecting plate 122 connected to each other may be formed in other manners according to user requirements, for example, by bending a metal plate, in other words, the first connecting plate 121 and the second connecting plate 122 may be integrally formed.

Both ends of gusset 123 respectively with first connecting plate 121 and second connecting plate 122 fixed connection to improve link 120's bulk strength through gusset 123, satisfy experimental demand. Specifically, the rib plate 123 is trapezoidal, and one waist thereof is fixedly connected to the first connecting plate 121, and the other waist thereof is fixedly connected to the second connecting plate 122. In this embodiment, the number of the rib plates 123 is two, and the two rib plates 123 are spaced apart and supported between the first connecting plate 121 and the second connecting plate 122, respectively, so as to ensure the strength of the connecting frame 120 through the cooperation of the two rib plates 123.

It is understood that in other embodiments, the degree of the included angle between the first connecting plate 121 and the second connecting plate 122 may be set according to the magnetic element 140 and the specific connecting position of the connecting rod and the main shaft 200. Optionally, pitch simulator 130 is fixedly connected to first connection plate 121 by bolts.

Optionally, the soft layer may be a leather layer, a sponge layer, a plurality of layers of adhesive tapes, etc., and can soften the setting surface to avoid scratching the surface of the spindle 200 when contacting the spindle 200.

With reference to fig. 1 and fig. 2, in the present embodiment, the number of the connecting rods is two, and the two connecting rods are respectively used for being correspondingly inserted into the two hub connecting holes 220 on the main shaft 200 one by one, so as to ensure the connection reliability of the pitch simulator 130 and the main shaft 200. It will be appreciated that in other embodiments, the number of connecting rods may be specifically set according to the user's requirement, for example, three connecting rods may be provided.

Specifically, one of the two connecting rods is fixedly connected to the second connecting plate 122, the connecting rod is a fixed rod 111, the other of the two connecting rods is movably connected to the second connecting plate 122, and the connecting rod is a movable rod 112, that is, the connecting rod includes the fixed rod 111 and the movable rod 112. By arranging the movable rod 112 movably connected with the second connecting plate 122, the distance between the fixed rod 111 and the movable rod 112 can be changed by the movement of the movable rod 112, so that the spindles 200 with different hole pitches can be matched, and the universality of the testing device 100 is improved.

It should be noted that, in the present embodiment, the connecting frame 120 is provided, and the fixed rod 111 and the movable rod 112 are connected to the pitch simulator 130 through the connection with the connecting frame 120, and it can be understood that, in other embodiments, the fixed rod 111 and the movable rod 112 may also be directly connected to the pitch simulator 130 according to requirements.

Further, the testing device 100 has a waist-shaped hole 124 matched with the movable rod 112, and the waist-shaped hole 124 extends along the direction that the fixed rod 111 points to the movable rod 112, i.e. after the movable rod 112 is installed in the waist-shaped hole 124, the connecting line of the fixed rod 111 and the movable rod 112 is consistent with the length direction of the waist-shaped hole 124. Therefore, by installing the movable rod 112 at different positions in the length direction of the kidney hole 124, the distance between the fixed rod 111 and the movable rod 112 can be changed. Therefore, when the testing device 100 is mounted on the main shaft 200 with different hole pitches, by adjusting the position of the movable rod 112, it is sufficient to ensure that the fixed rod 111 and the movable rod 112 can be correspondingly plugged with two different hub mounting holes at the same time.

The limiting protrusion 1122 is cylindrical and has a radial dimension greater than the width of the slotted hole 124. Further, one end of the rod portion 1121, which is close to the limit protrusion 1122, is provided with a matching step 1123, and the matching step 1123 is used for matching with the kidney-shaped hole 124, so that the movable rod 112 is clamped in the kidney-shaped hole 124, and when the position of the movable rod 112 needs to be changed, the movable rod 112 is lifted up, so that the matching step 1123 of the movable rod 112 is separated from the kidney-shaped hole 124.

Referring to fig. 1, in the embodiment, the connecting rod includes a rod body 113 and a sleeve 114 sleeved on the cylinder body, the rod body 113 is connected to the pitch simulator 130, the sleeve 114 is detachably connected to the rod body 113, and the sleeve 114 is used for being connected to the hub connection hole 220, so that the testing device 100 can better adapt to testing requirements of various spindles 200 with different specifications. The internal diameter size of sleeve 114 suits with the external diameter of the body of rod 113, and the external diameter size of sleeve 114 suits with the aperture of wheel hub connecting hole 220, so when the main shaft 200 to the wheel hub connecting hole 220 that has different apertures, can satisfy experimental installation demand through changing sleeve 114, has further promoted test device 100's application scope, helps reducing test cost. Specifically, the outer diameter of the rod 113 is set to be smaller than the diameter of the smallest hub connecting hole 220 of the main shafts 200 of the same series, for example, the outer diameter of the rod 113 of the testing device 100 is set to be smaller than 39mm for the power of 2MW product series, and therefore the testing device 100 can meet the testing requirements of the main shafts 200 of the 2MW product series by replacing the sleeves 114 with different outer diameters.

Specifically, for the fixing rod 111, the rod body 113 of the fixing rod 111 is in a circular tube shape, and is fixedly connected to the second connecting plate 122 by welding. For the movable rod 112, the rod body 113 of the movable rod 112 is formed by connecting a rod portion 1121, a matching step 1123 and a limiting bump 1122, and when in use, the sleeve 114 is sleeved on the rod portion 1121, that is, the inner diameter of the sleeve 114 of the movable rod 112 is matched with the outer diameter of the rod portion 1121 of the movable rod 112. Optionally, the sleeve 114 is a soft plastic sleeve to help prevent the sleeve 114 from damaging the hub attachment bore 220 of the spindle 200.
