Description

Shaft sleeve holder for motor gear coupling

This model relates to a retainer, especially a shaft sleeve retainer of a motor gear coupling.

After the large motor is overhauled and maintained, or when the equipment vibrates too much, and it is necessary to clarify whether the motor itself is abnormal or the equipment driven by the motor (such as fans, pumps, etc.) is abnormal, the coupling must be disconnected and separated. Let the motor run idling to determine whether the state of the motor is normal.

The shaft sleeve of the coupling must be fixed to the shaft center of the motor before the motor is idling. Otherwise, when the motor is running, the shaft sleeve will jump with the rotation of the motor, which will cause the If the motor is unbalanced, it may cause damage to the shaft or the internal gear of the sleeve.

At present, the method of fixing the shaft sleeve of the coupling to the shaft center of the motor is to fix the shaft sleeve on the shaft center using iron wires. However, because the shaft center is a smooth cylindrical surface, it is not easy to tie the iron wire tightly. If a too thick iron wire is used, it is difficult to fix the shaft sleeve on the shaft center. On the contrary, if the iron wire is too thin, the iron wire may be fracture. And during the idling test of the motor, the rotation speed of the shaft sleeve is equal to the rotation speed of the motor, so the shearing surface of the iron wire will become a sharp edge, and the iron wire may also break and fly out during the rotation process. It can cause personal injury and damage the equipment.

Therefore, in view of the disadvantage that the existing method of fixing the shaft sleeve to the shaft center by using iron wires has the disadvantage of time-consuming, and the motor may cause personal injury and damage the equipment when the motor is trying to run idling. Therefore, it is necessary to find a solution.

Therefore, the purpose of the present invention is to provide a shaft sleeve holder for a motor gear coupling.

Therefore, the shaft sleeve holder of the new motor gear coupling is suitable for fixing a shaft sleeve of a gear coupling in a disconnected state with a motor including a shaft center for a test idling. , Move the shaft sleeve of the gear coupling away from the motor to create an accommodation space between the motor body and the shaft sleeve of the gear coupling, so that the shaft sleeve holder of the motor gear coupling It can be installed between the shaft sleeve and the motor. When the shaft sleeve and the motor are separated by the accommodating space, the shaft is limited in the shaft sleeve but cannot be fixed. The shaft sleeve of the gear coupling is fixed The device includes: two substrates, each substrate includes a base surface, a clamping edge perpendicular to the base surface and used for clamping the shaft, and at least one axial screw hole, wherein the clamping edge has a On the V-shaped notch section that conflicts with the axis, and two extension sections extending outward from both ends of the V-shaped notch section; two clamping plates are respectively integrally connected to the substrates, wherein each clamp The tight plate extends vertically from the other side of the corresponding base plate opposite to the base surface, and includes a V-shaped plate portion for colliding with the V-shaped notch section of the clamping edge of the corresponding base plate, and two separate self The two ends of the V-shaped plate are extended outwards, wherein each extension is provided with a plurality of clamping screw holes; the plurality of clamping screws correspond to the clamping of the clamping plates.
