Description

Technical Field

[0001] The utility model relates to the field of motor shafts, and more specifically, to a motor shaft with high stability. Background Art

[0002] "Motor" refers to electric motors and engines. The working principle is that the starter rotor rotates through the energized coil under force in the magnetic field, and the small gear on the rotor drives the engine flywheel to rotate. The output shaft is one of the important components of the motor, such as the output shaft in the CM-20 motor model. The output shaft is the power output. For example, a motor converts electrical power, hydraulic pressure or gas pressure into mechanical power. The output shaft stably transmits torque when the motor is working.

[0003] The driving shaft of the motor will be affected by the vibration of the motor itself during operation, resulting in unstable rotation of the motor shaft; to address this problem, the Chinese utility model with application number 202221866855.9 proposes a high-stability rust-proof motor shaft, including a shaft rod, a fitting ring and a vibration-damping assembly, the vibration-damping assembly including a top plate, an insertion rod, a rod sleeve, a chassis, a spring, a rubber inner sleeve and a rubber outer sleeve, the bottom end of the fitting ring is welded with a top plate, the bottom end of the top plate is welded with an insertion rod that cooperates with the rod sleeve, the bottom end of the rod sleeve is integrally formed with a chassis, the spring is sleeved on the outer wall of the insertion rod, and the ends of the spring are respectively fixed to the top plate and the rod sleeve, and the inner wall of the rod sleeve is bonded with a rubber inner sleeve. The high-stability rust-proof motor shaft is fixed by bolts through the chassis. During the operation of the motor shaft, the rod is inserted and extended and retracted up and down along the inner wall of the rod sleeve. The spring is compressed and rebounded by the vibration. During this process, the rubber outer sleeve and the rubber inner sleeve are constantly rubbed up and down. The damping force generated by the fitting movement of the two stabilizes the spring, and then the entire vibration reduction assembly and the motor shaft reach a stable state. However, the problems existing in the device when in use are:

[0004] Since the shaft needs to be connected to external components when used for driving, the vibration damping component therein cannot ensure the stability of the shaft end position and the external component connection position, affecting the subsequent stable torque output of the shaft; at the same time, the device cannot stably reinforce the connection end position of the shaft and the motor itself, and cannot complete the integrated installation with the motor itself, and the convenience of use needs to be improved.

The inner surface of the third connecting seat is provided with two groups of arc-shaped mounting grooves corresponding to the support ring.

[0025] In the embodiment of the utility model, the upper auxiliary structure 4 includes a first connecting seat 8, a second connecting seat 9 and a docking plate 10 which are matched with each other. The first connecting seat 8 and the second connecting seat 9 are both embedded with a fitting sleeve 11. The docking plate 10 and the first connecting seat 8 are fixedly connected, and the second connecting seat 9 and the docking plate 10 are slidably sleeved. The first connecting seat 8 and the second connecting seat 9 are respectively arranged in an "L"-shaped seat body and a rectangular seat body. The bottom surfaces of both are arc-shaped and concave. The fitting sleeve 11 is also arc-shaped. At the same time, the fitting sleeve 11 is arranged to fit the upper surface of the shaft body 6. An arc-shaped oil storage tank is arranged on the inner surface of the fitting sleeve 11. The second connecting seat 9 and the docking plate 10 which are slidably connected can achieve the effect of adjusting the length of the position above the shaft body 6, and can cooperate with the fitting sleeve 11 to achieve the effect of contacting the shaft body 6 to ensure its rotation stability.

[0026] The user can adjust the length of the second connecting seat 9 above the shaft body 6 and cooperate with the interlocking sleeve 11 to fit the shaft body 6 to ensure the stability of the shaft body 6. When the shaft body 6 rotates, the upper surface can effectively suppress the vibration generated during the driving process under the action of the first connecting seat 8, the second connecting seat 9 and the interlocking sleeve 11, thereby ensuring the rotation stability of the shaft body 6.

[0027] The lower auxiliary structure 5 includes a third connecting seat 12 and a support ring 14 on its inner side. The inner surface of the third connecting seat 12 is provided with two groups of arc-shaped mounting grooves 13 corresponding to the support ring 14.

The support ring 14 is used to form a socket support for the shaft body 6 from the bottom, thereby ensuring its driving stability. The mounting groove 13 is used to limit the installation of the support ring 14 on the inner side of the third connecting seat 12.

[0028] When the shaft body 6 rotates, the lower surface can effectively suppress the vibration generated during the driving process under the action of the support ring 14, thereby ensuring the rotation stability of the shaft body 6 and providing support for the shaft body 6.
