[0013] A method for using an auxiliary device for detecting the concentricity of gear shafts in a speed increaser gearbox includes the following steps:

[0014] Step 1: First, personnel need to check the concentricity of the fixed shaft and the rotating shaft inside the speed increaser. At this time, the test head and lever gauge need to be fixed on the lever gauge fixing hole of the adjusting rod. Then, the rotating shaft can be tested when it rotates.

[0015] Step 2: During the test, the starting position of the positioning bracket can be freely adjusted using the adjusting rod. To better adjust the adjusting rod, the operator can rotate the adjusting rod up and down using the rotating auxiliary component, which allows for better rotation testing of the shaft and the fixed rod.

[0016] Step 3: Subsequently, the positioning bracket is used to position the key parts of the gear shaft inside the speed increaser gearbox. In order to improve the positioning effect, the staff will lift the structure inside the auxiliary component to more easily fix the rotating shaft under the control of the fixing rod.

[0017] Step 4: After the lever gauge is adjusted to the correct position during testing, the lever gauge is fixed and locked by the lever gauge locking nut. The lever gauge is also locked through the lever gauge fixing hole. After the testing head on one side of the lever gauge is adjusted through the lever gauge fixing hole, it is locked by the lever gauge locking nut. Then, the positioning pin is used to ensure full contact with the rotating shaft inside the speed increaser gearbox when testing the concentricity of the gear shaft and the gearbox.

[0018] This invention provides an auxiliary device for detecting the concentricity of gear shafts in a speed increaser gearbox. It has the following advantages:

[0019] 1. This invention addresses the limitation of traditional testing tools, which are limited to ordinary measuring tools like tape measures. These tools cannot guarantee that the dimensional deviation of the concentricity between the gear shaft and the gearbox body within the speed increaser gearbox is controlled within 0.3mm. The positioning bracket, which can be freely adjusted via an adjusting rod, is used to position the key component of the gear shaft within the speed increaser gearbox. A locking nut is used to lock the lever after the positioning bracket is adjusted. A lever gauge locking nut is used to fix the lever after it is adjusted during testing. A lever gauge fixing hole is used to lock the lever gauge fixing rod after it is adjusted. During the concentricity test of the gear shaft and gearbox body within the speed increaser gearbox, the positioning pin ensures full contact with the gear shaft.

[0020] 2. This invention, through the cooperation of a rotation auxiliary component and a lifting auxiliary component, facilitates the operation of personnel when inspecting concentricity shafts. Subsequently, by accurately measuring and fixing the inspection head on the rotating shaft through the up-and-down movement of the lifting auxiliary component, better concentricity detection can be achieved. Furthermore, the use of the rotation auxiliary component makes it easy for personnel to adjust the direction of the rotating shaft. Attached Figure Description
