Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
A motor shaft transmission device capable of adjusting the axial position as shown in figures 1-2 comprises a motor 1, a transmission wheel 2 and a locking taper sleeve 3, wherein the transmission wheel 2 and the locking taper sleeve 3 are both arranged on an output shaft of the motor 1. The driving wheel 2 is any one of a chain wheel, a belt wheel and a gear. The drive wheel 2 has a central conical bore 21 which is typically large on the outside and small on the inside relative to the motor 1. The locking taper sleeve 3 is provided with a taper connecting part 31 matched with the central taper hole 21, and the locking taper sleeve 3 is also provided with a disk-shaped locking part 32 opposite to the end surface of the driving wheel 2. The disc-shaped locking part 32 is provided with a compression bolt 4, the end surface of the driving wheel 2 is provided with a threaded hole matched with the compression bolt 4, and the locking taper sleeve 3 is provided with an axially through expansion joint 33; after the driving wheel 2 is positioned on the shaft of the motor 1, the conical connecting part 31 of the locking taper sleeve 3 extends into the central taper hole 21, the pressing bolt 4 is screwed up, the driving wheel 2 and the locking taper sleeve 3 are close to each other under the action of the pulling force of the pressing bolt 4, the central taper hole 21 applies pressure to the outside of the locking taper sleeve 3, the inner diameter of the locking taper sleeve 3 is reduced, the expansion joint 33 is narrowed, the connecting pressure between the locking taper sleeve 3 and the motor shaft is increased, and the motor shaft, the driving wheel 2 and the locking taper sleeve 3 are connected.
In order to accommodate the contraction movement of the disc-shaped locking portion 32, the disc-shaped locking portion 32 has a strip-shaped hole to be fitted with the locking bolt 4. The length of the strip-shaped hole is not less than the sum of the width of the expansion joint 33 and the diameter of the compression bolt 4, so that the hole position difference caused by the extension motion of the disc-shaped locking part 32 along the circumferential direction can be offset; the width of the strip-shaped hole is not less than the sum of the diameter of the compression bolt 4 and the deviation X of the outer diameter of the locking taper sleeve 3, wherein X is the variation of the outer diameter of the disk-shaped locking part in 32 times compression.
In order to facilitate disassembly, the pan head locking portion 32 is further provided with a disassembly bolt 5, the disassembly bolt 5 is in threaded fit connection with the pan head locking portion 32, and the small end of the disassembly bolt 5 can tightly push against the end face of the transmission wheel 2 to separate the transmission wheel 2 from the locking taper sleeve 3.
In the embodiment, the taper of the tapered connecting part 31 is consistent with that of the central taper hole 21, and repeated tests show that the taper is selected to be 1: 10-1: 5, the best effect is achieved, the adjusting stroke is too long when the taper is less than 1:10, and the adjusting effect is not obvious; when the taper is larger than 1:5, the contact surface between the central taper hole 21 and the taper connecting part 31 is too small, the radial pressure on the motor shaft is small, and the connection reliability is poor.
In this embodiment, the end face of the contact between the pressing bolt 4 and the disc-shaped locking portion 32 is provided with a gasket, so that on one hand, the contact area of the large end of the pressing bolt 4 can be increased, and on the other hand, the gasket can reduce the friction force generated when the disc-shaped locking portion 32 and the pressing bolt 4 move relatively.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the embodiments are only used to help understanding the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the present description should not be construed as a limitation to the present invention.
