[0017] A second pressure plate 21 is distributed on the upper end of the first pressure plate 2, and a limiting shaft connecting plate 4 is inserted and fixed on the upper surface of the first pressure plate 2. A rotating shaft 31 is inserted on the inner side of the limiting shaft connecting plate 4 through a limiting groove 43. A magnet block 41 is adsorbed on the upper surface of the rotating shaft 31.

The side wall of the limiting groove 43 is connected to a supporting side plate 5 through a spring 51, and the side end of the supporting side plate 5 is fitted with the axial surface of the rotating shaft 31 through a ball 53.

[0018] Working principle: When testing the axial force of the reduction gearbox, first place the reduction gearbox body 3 on the axial force test frame 1, so that the rotating shaft 31 connected to the bearing of the reduction gearbox body 3 faces upward, and then move the first pressure plate 2 to make the rotating shaft 31 inserted into the limiting groove 43 of the limiting shaft connecting plate 4, so that the upper end of the rotating shaft 31 is adsorbed on the magnet block 41, and the supporting side plate 5 on the side of the limiting groove 43 slides in contact with the axial surface of the rotating shaft 31, and place the breeding block on the second pressure plate 21, so that the second pressure plate 21 is pressed down on the limiting shaft connecting plate 4 on the surface of the first pressure plate 2, and then energize the reduction gearbox body 3 to make the rotating shaft 31 rotate continuously for a period of time, and observe whether there is obvious noise. If there is no obvious noise, the reduction gearbox bearing can meet the load-bearing requirements of the maximum axial force, otherwise it does not meet the requirements.

[0019] In this embodiment, a fixed base 12 is screwed and installed at the lower end of the axial force test frame 1 , and a guide shaft 11 is welded on the upper surface of the fixed base 12 ; and the guide shafts 11 are symmetrically distributed on the left and right sides of the axial force test frame 1 .

[0020] As a preferred embodiment, the fixed base 12 is convenient for supporting the axial force test frame 1. The upper end of the guide shaft 11 is screwed with a limit block to prevent the first pressure plate 2 and the second pressure plate 21 from moving out of the surface of the guide shaft 11.

[0022] As a preferred embodiment, the weight-bearing platform 23 can be placed with a breeding block, so that the second pressure plate 21 is pressed down on the limiting shaft connecting plate 4 on the surface of the first pressure plate 2, thereby applying pressure and weight to the rotating shaft 31.

[0023] In this embodiment, the left and right side plates of the axial force test frame 1 are connected to the clamping plates 13 through the adjusting studs 14 , and the clamping plates 13 are symmetrically clamped and fitted on the left and right sides of the reduction gear box body 3 .

[0024] As a preferred implementation, the axial force test frame 1 moves the clamping plate 13 by rotating the adjusting stud 14 so that the clamping plate 13 is clamped on the left and right sides of the reduction box body 3, thereby conveniently clamping and fixing the reduction box body 3 on the axial force test frame 1.

[0025] In this embodiment, handles 22 are installed on the front and rear sides of the second pressure plate 21 , and the outer ends of the supporting side plates 5 are connected to the limiting shaft connecting plate 4 through the connecting plate 52 .

[0026] As a preferred embodiment, the handle 22 facilitates the carrying of the axial force testing device, and the overall structure of the axial force testing device is simple, making it convenient for daily carrying and use.

[0027] In this embodiment, the first pressure plate 2, the second pressure plate 21, the limiting shaft connecting plate 4, the magnet block 41, the rotating disk 42, the supporting side plate 5 and the spring 51 constitute an axial force load-bearing mechanism.

[0029] The portable reducer axial force test device of the utility model can effectively solve the problem that the existing axial force test device is difficult to apply pressure stably and bear weight on the rotating shaft, enhance the stability of the axial force pressure test of the reducer, and prevent the shaft of the reducer and the pressure plate from colliding and wearing.
