Embodiment 1

[0051] Such as Figure 1 to Figure 14 As shown, a test gear removal device, the motor test gear 2 is tightly connected with the motor shaft 1, including a chuck 3 for clamping the motor test gear 2, and for rigidly connecting with the end face of the motor shaft 1 The positioning shaft 4 and the power mechanism connected to the positioning shaft 4.

[0052] When using, you can perform the following steps:

[0053] S1, the chuck 3 clamps the motor test gear 2, the positioning shaft 4 is rigidly connected to the end face of the motor shaft 1, and the power mechanism is connected to the positioning shaft 4;

[0054] S2, start the power mechanism, so that the power mechanism drives the motor shaft 1 to move in the direction of falling off from the motor test gear 2 .

[0055] Using the present invention can effectively dismantle the motor test gear 2, avoiding the problem that the motor test gear 2 cannot fall off from the motor shaft 1 due to the leakage problem, and avoiding t...

Embodiment 2

[0071] Such as Figure 1 to Figure 14 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:

[0072] A method for using the test gear removal device includes the following steps:

[0073] S1, the chuck 3 clamps the motor test gear 2, the positioning shaft 4 is rigidly connected to the end face of the motor shaft 1, and the power mechanism is connected to the positioning shaft 4;

[0074] S2, start the power mechanism, so that the power mechanism drives the motor shaft 1 to move in the direction of falling off from the motor test gear 2 .

[0075] Using the present invention can effectively dismantle the motor test gear 2, avoiding the problem that the motor test gear 2 cannot fall off from the motor shaft 1 due to the leakage problem, and avoiding the economy caused by heating and cutting the motor test gear 2 and causing the motor t...

Embodiment 3

[0080] Such as Figure 1 to Figure 14 As shown, this embodiment includes all the technical features of Embodiment 1 and Embodiment 2. On the basis of Embodiment 1 and Embodiment 2, this embodiment provides a more detailed implementation mode.

[0081] What the present invention describes is a kind of motor test gear removal device, which is provided with a chuck 3, a hoop 5, a positioning ring 6, a screw 8, a backing plate 9, a top plate 7 and a positioning shaft 4, etc. When in use, the device hoops the motor test gear 2, and applies axial pressure to the hydraulic cylinder 10 by using a 35t or 50t hydraulic cylinder 10 and a hydraulic station / hydraulic pump, so that the motor test gear 2 can be pulled out. The device is compact, convenient and efficient to use, and widely used, and is suitable for removing the motor test gear 2 of the motor.

[0082] Install the backing plate 9 and the positioning shaft 4 on the end face of the motor shaft 1, put the chuck 3 on the inner en...

Abstract

The invention discloses a test gear dismounting device and a use method thereof. The test gear dismounting device comprises a motor rotating shaft, a motor test gear tightly sleeving the motor rotating shaft, a chuck clamping the motor test gear, a positioning shaft rigidly connected to the end face of the motor rotating shaft, and a power mechanism connected to the positioning shaft. According to the test gear dismounting device and the use method thereof, the problem that in the prior art, if an existing method for expanding the inner surface of the test gear is still adopted, the test gear cannot fall off from the rotating shaft due to leakage is solved.

Description

technical field [0001] The invention relates to the technical field of motor disassembly, in particular to a test gear disassembly device and a use method thereof. Background technique [0002] Due to the repeated heating, fitting and removal of the motor test gear, it will inevitably lead to poor contact between the inner surface of the motor test gear and the outer surface of the rotating shaft after repeated use. If the existing method of expanding the inner surface of the test gear is still used, The test gear will not come off the shaft due to leakage issues. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a test gear disassembly device and its use method, which solves the existing problem in the prior art that if the existing method of expanding the inner surface of the test gear is still used, the test gear will leak due to leakage. And can not fall off from the shaft and other problems. [...
