Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features.
[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application.
[0029] The embodiment of the present application provides a gear shaft testing device to solve the problem of insufficient accuracy of gear shaft testing results. The following will be described in combination with the drawings.
[0030] The embodiment of the present application provides a gear shaft testing device, which comprises a first fixing member 1 and a second fixing member 2 arranged at intervals, the first fixing member 1 is provided with a fixing groove 11 for fixing a gear on one side close to the second fixing member 2, and the second fixing member 2 is provided with a fixing hole 21 for the one end of a rotating shaft to extend into on one side close to the first fixing member 1.
[0031] The first fixing member 1 is arranged to fix the gear on the gear shaft 4, and the second fixing member 2 is arranged to fix the rotating shaft on the gear shaft 4. When the staff tests the gear shaft 4, an external force is applied to the second fixing member 2 to make the core axis of the rotating shaft deviate from the core axis of the gear until the side edge of the second fixing member 2 abuts against the first fixing member 1, so that the simulation of the external force applied to the gear shaft 4 is realized. Since the abutment of the side edge of the second fixing member 2 against the first fixing member 1 is the termination condition of the external force application each time, the same external force condition can be maintained each time, and the problem of insufficient accuracy of the gear shaft 4 testing results is solved.
[0032] In the embodiment, the second fixing member 2 is integrally formed with a measuring ring 22 extending to one side of the first fixing member 1. In some embodiments of the present application, the measuring ring 22 is detachably connected with the second fixing member 2. Specifically, the second fixing member 2 is provided with a plurality of locking members 23, and the second fixing member 2 is provided with a threaded hole on one side close to the first fixing member 1. The measuring ring 22 is provided with a countersunk through hole. The locking members 23 are arranged to penetrate through the countersunk through hole and be threadedly connected with the threaded hole, so that the measuring ring 22 is detachably connected with the second fixing member 2. By detachably connecting the measuring ring 22 with the second fixing member 2, different lengths of the measuring ring 22 can be replaced on the second fixing member 2, so that the adjustment of the bending degree of the rotating shaft is realized.
[0033] In some embodiments of the present application, the second fixing member 2 is provided with a fixing plate 24, which is detachably connected to the side of the second fixing member 2 close to the first fixing member 1, and the fixing hole 21 is formed in the fixing plate 24.

The fixing plate 24 is provided with an external thread matched with the internal thread, and the fixing plate 24 is threadedly connected with the second fixing member 2. By threadedly connecting the fixing plate 24 with the second fixing member 2, different diameters of the fixing hole 21 can be formed in different fixing plates 24, and by replacing different fixing plates 24, the second fixing member 2 can meet the fixing requirements of different diameter shafts. The side of the fixing plate 24 close to the first fixing member 1 is provided with a fixing cylinder 25, which is in communication with the fixing hole 21. The provision of the fixing cylinder 25 is conducive to the connection of the second fixing member 2 with the shaft.
[0034] In some embodiments of the present application, the gear shaft testing device further comprises a base 3, which is provided with a storage groove 31 and a sliding groove 32. The storage groove 31 is in communication with the sliding groove 32, and each sliding groove 32 is slidably connected with a locking member 33. The locking member 33 connects the base 3 and the first fixing member 1 to fix the first fixing member 1 on the base 3. The storage groove 31 is used to accommodate the first fixing member 1, and the locking member 33 is slidably connected with the sliding groove 32. The locking member 33 is provided with a positioning column, and the first fixing member 1 is provided with a positioning hole matched with the positioning column. By inserting the positioning column into the positioning hole, the detachable connection of the first fixing member 1 with the base 3 can be achieved. By forming different fixing grooves 11 in different first fixing members 1, different first fixing members 1 can be arranged on the base 3 to meet the fixing requirements of different sizes of gears.
[0035] In some embodiments of the present application, the locking member 33 is provided with an engaging surface close to the first fixing member 1, and the engaging surface is in contact with the side wall of the first fixing member 1. The positioning column is arranged on the engaging surface. The locking member 33 is provided with a locking member 34, which is rotationally matched with the locking member 33. The bottom of the sliding groove 32 is provided with a locking hole, and the locking member 34 penetrates through the locking member 33 and is connected with the locking hole.

In the above embodiments, the description of each embodiment focuses on different aspects, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.
