A motor shaft mounting mechanism

Abstract

This utility model discloses a motor shaft mounting mechanism, including a motor shaft and a connecting shaft, with a connecting mechanism between the motor shaft and the connecting shaft. The connecting mechanism includes a connecting rod, a first slot, a movable cylinder, a second slot, a locking block, a cavity, a movable block, a spring, and a pressing block. The first slot is located on the outside of the connecting rod. This utility model moves the connecting rod between the motor shaft and the connecting shaft, then moves the motor shaft and the connecting shaft into the first slot of the connecting rod, simultaneously aligning the locking block with the second slot. The movable cylinder is then rotated, moving along the upper end of the connecting rod until it reaches the inclined surface of the pressing block, causing the pressing block to move downwards along the cavity, thus stretching the spring. At this point, the locking block moves downwards into the second slot. This securely connects the motor shaft and the connecting shaft, and the locking block bears the torque, preventing instability in the fixed connection caused by the torque on the bolts during bolted connections.

Description

Technical Field

[0001] This utility model relates to the field of motor shaft mounting, specifically a motor shaft mounting mechanism. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., the stator winding) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric torque.

[0003] When the existing motor shaft is extended or connected to an adjacent shaft, it is fixed by a large number of bolts. After the bolt connection, the torque is directly applied to the bolt, which makes the threads on the outside of the bolt very easy to wear, resulting in a decrease in the connection strength. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a motor shaft mounting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor shaft mounting mechanism, comprising a motor shaft and a connecting shaft, wherein a connecting mechanism is provided between the motor shaft and the connecting shaft, the connecting mechanism comprising a connecting rod, a first slot, a movable cylinder, a second slot, a locking block, a cavity, a movable block, a spring, and a pressing block; the first slot is located on the outside of the connecting rod, the movable cylinder is threaded onto the outside of the connecting rod, the second slot is located on the outside of the motor shaft and the connecting shaft, the cavity is located inside the connecting rod, the movable block is slidably disposed inside the cavity, the locking block is fixed on the side of the movable block away from the movable cylinder, and the spring is fixed between the movable block and the inner wall of the cavity. The compression block is fixed on the side of the movable block near the movable cylinder. In use, the connecting rod is moved between the motor shaft and the connecting shaft, and then the motor shaft and the connecting shaft are moved into the first slot of the connecting rod, while the compression block is aligned with the second slot. Then the movable cylinder is rotated, so that the movable cylinder moves along the upper end of the connecting rod until it is pressed against the inclined surface of the compression block, so that the compression block moves downward along the cavity, thereby stretching the spring. At this time, the compression block moves downward and moves into the second slot. In this way, the connecting rod is fixedly connected to the motor shaft and the connecting shaft, and the compression block bears the torque, thus preventing the instability of the fixed connection caused by the torque on the bolt during bolt connection.

[0006] Preferably, there are two first slots, symmetrically located on both sides of the connecting rod.

[0007] Preferably, there are two movable cylinders, which are symmetrically installed on both sides of the connecting rod.

[0008] Preferably, the card block fits into the second card slot.

[0009] Preferably, the spring is sleeved on the outside of the compression block.

[0010] Preferably, the top of the extrusion block has a smooth inclined surface near the movable cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention involves moving the connecting rod between the motor shaft and the connecting shaft, then moving the motor shaft and the connecting shaft into the first slot of the connecting rod, simultaneously aligning the locking block with the second slot. The movable cylinder is then rotated, moving along the upper end of the connecting rod until it reaches the inclined surface of the pressing block. This causes the pressing block to move downwards along the cavity, stretching the spring. At this point, the locking block moves downwards into the second slot, thus fixing the connecting rod to the motor shaft and the connecting shaft. The locking block also bears the torque, preventing instability in the fixed connection caused by the torque on the bolts during bolted connections. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a motor shaft mounting mechanism, including a motor shaft 1 and a connecting shaft 2. A connecting mechanism is provided between the motor shaft 1 and the connecting shaft 2. The connecting mechanism includes a connecting rod 3, a first slot 5, a movable cylinder 4, a second slot 8, a locking block 9, a cavity 6, a movable block 7, a spring 10, and a pressing block 11. The first slot 5 is located on the outside of the connecting rod 3, and there are two first slots 5, symmetrically located on both sides of the connecting rod 3. The movable cylinder 4 is threaded onto the outside of the connecting rod 3, and there are two movable cylinders 4, symmetrically installed on both sides of the connecting rod 3. The second slot 8 is located on the outside of the motor shaft 1 and the connecting shaft 2. The cavity 6 is located inside the connecting rod 3. The movable block 7 is slidably disposed inside the cavity 6. The locking block 9 is welded and fixed to the side of the movable block 7 away from the movable cylinder 4. The locking block 9 fits into the second slot 8. The spring 10 is welded and fixed to the movable block 7. Between the inner wall of cavity 6, the extrusion block 11 is welded and fixed to the movable block 7 near the movable cylinder 4. The spring 10 is sleeved on the outside of the extrusion block 11. The top of the extrusion block 11 near the movable cylinder 4 is a smooth inclined surface. In use, the connecting rod 3 is moved between the motor shaft 1 and the connecting shaft 2, and then the motor shaft 1 and the connecting shaft 2 are moved into the first slot 5 of the connecting rod 3. At the same time, the locking block 9 is aligned with the second slot 8. Then the movable cylinder 4 is rotated so that the movable cylinder 4 moves along the upper end of the connecting rod 3 until the inclined surface of the extrusion block 11 is pressed. This causes the extrusion block 11 to move downward along the cavity 6, thereby stretching the spring 10. At this time, the locking block 9 moves downward and moves into the second slot 8. In this way, the connecting rod 3 is fixedly connected to the motor shaft 1 and the connecting shaft 2, and the locking block 9 bears the torque. This prevents the fixed connection from being unstable due to the torque on the bolt during bolt connection.

[0016] Working principle: When in use, move the connecting rod 3 between the motor shaft 1 and the connecting shaft 2, then move the motor shaft 1 and the connecting shaft 2 into the first slot 5 of the connecting rod 3, while aligning the locking block 9 with the second slot 8. Then rotate the movable cylinder 4, causing it to move along the upper end of the connecting rod 3 until it reaches the inclined surface of the pressing block 11, causing the pressing block 11 to move downward along the cavity 6, thereby stretching the spring 10. At this time, the locking block 9 moves downward into the second slot 8, thus fixing the connecting rod 3 to the motor shaft 1 and the connecting shaft 2, and bearing the torque through the locking block 9, thus preventing the instability of the fixed connection caused by the torque on the bolt during bolt connection.
