Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Referring to fig. 1 to 4, a clothes drying machine driving device comprises a main shell 1, a motor 2, a rope winding wheel 3, a chassis 4 and a stroke limiting device 5.

The main housing 1 includes an upper cover 11 and a lower cover 12 that are fastened together, and an accommodating space is formed between the upper cover 11 and the lower cover 12, and the sheave 3 is disposed in the accommodating space. The motor 2 is arranged at the adjacent position of the main shell 1, the chassis 4 is arranged below the lower cover 12 and is used for connecting and fixing with an external installation base (installation bracket), and the stroke limiting device 5 is arranged above the upper cover 11.

The rope winding wheel 3 comprises a main driving disc 31 and a rope winding disc which are coaxially fixed, in the embodiment, the rope winding disc comprises three wheel discs 32 which are arranged at an upper interval and a lower interval, and the main driving disc 31 and the three wheel discs 32 can synchronously rotate. The bottom of the uppermost disk 32 has a first spacer 321 having a disk shape, and the bottom of the middle disk 32 has a second spacer 322 having a disk shape, and the first spacer 321, the second spacer 322, and the disk 32 are coaxially arranged. A first wheel groove 323 is thus formed between the uppermost wheel disc 32 and the middle wheel disc 32, a second wheel groove 324 is formed between the middle wheel disc 32 and the lowermost wheel disc 32, and the first wheel groove 323 and the second wheel groove 324 are arranged parallel to each other and spaced apart in the axial direction. The washing line may be received in the first wheel groove 323 (outer periphery of the first spacer 321) and the second wheel groove 324 (outer periphery of the second spacer 322). And the outer diameter of the outermost turn of the coiled line is not greater than the outer diameter of the wheel disc 32. The main transmission disc 31 is positioned below the wheel disc 32 and is used for being in transmission connection with the motor 2. The three wheel discs 32 and the main drive disc 31 are coaxially fixed by means of two jackbolt pins 34, ensuring synchronous rotation.

The motor 2 is arranged adjacent to the main housing 1, an output shaft 21 of the motor 2 extends into the main housing 1, a worm 22 is arranged on the output shaft 21 of the motor 2, the worm 22 is meshed with a main transmission disc 31 (the worm 22 extends in the tangential direction of the main transmission disc 31), and the main transmission disc 31 is of a worm gear structure. Thus, when the motor 2 is operated, the main drive disc 31 can be rotated by the worm 22. The worm and gear structure has the effect of speed reduction. In addition, further, the main transmission disc 31 and the wheel disc are coaxially fixed, and the outer diameter of the main transmission disc 31 is larger than that of the wheel disc, so that the tangential linear velocity of the wheel disc is smaller than that of the main transmission disc 31 under the condition that the angular velocities of the main transmission disc and the wheel disc are the same, and therefore the main transmission disc 31 plays a role in further transmission and speed reduction. Because main drive dish 31 and each rim plate (race) coaxial arrangement for the radial dimension of main drive dish 31 can be as big as possible relative race to increase the reduction ratio, under the unchangeable condition of motor 2's power, the output torque of motor 2 has showing the increase after passing through rope sheave 3 compared with prior art, consequently can improve the load capacity of load.

The periphery of the main housing 1 is opened with two outlets 13, in this embodiment, the outlets 13 are opened on the periphery of the upper cover 11, and the two outlets 13 are arranged at intervals, and are symmetrical with respect to the center of the rope winding wheel 3.

Referring to fig. 5 and 6, the driving device is mounted on the bracket 100, and two clotheslines 7 wound in the first wheel groove 323 and the second wheel groove 324 are respectively led out from the corresponding outlet ports 13 and wound on the winding pulleys 101 arranged at both ends of the mounting bracket 100 in the length direction. The outlet 13 is staggered from the central axis X of the mounting bracket 100 in the length direction, and the two outlets 13 are respectively located on two sides of the central axis X. Therefore, after each clothesline 7 is led out from the symmetrical outlet 13, because the clotheslines 7 on both sides of the driving device are simultaneously connected with the load, the clotheslines 7 respectively generate a tensile force with the same magnitude on both sides of the driving device, and after the two tensile forces are decomposed, the component forces in the central axis X and the vertical direction thereof are corresponding (as shown by arrows in fig. 6), so that the two tensile forces are mutually offset, and the driving device is more stable in the operation process.

Because the worm and gear transmission structure is adopted between the motor 2 and the rope winding wheel 3, the motor 2 can be transversely arranged on the support 100 and extend along the length direction of the support 100, because the length of the support 100 is usually far greater than the width, the adjusting range of the relative position of the driving device and the support 100 is enlarged, under the condition that the width of the support 100 of the clothes airing machine is certain, the angle of the driving device relative to the central axis X of the support 100 is more convenient to rotate, so that the wire outlet 13 of the clothes airing rope 7 is close to the central axis X of the support 100 as much as possible, and the work of the clothes airing machine is stable. And through rotatory airing machine drive arrangement, for airing machine drive arrangement in figure 7, make the motor of same volume size can place in littleer airing machine support width, saved the space, the cost is reduced.
