Detailed Description
Fig. 1 shows a perspective view of a dryer equipped with a pulley assembly for transmitting driving force according to the present invention. Fig. 2 is a perspective view showing a state in which a pulley assembly for transmitting a driving force according to the present invention is installed in a dryer. Fig. 3 is a side view showing a dryer mounted with a pulley assembly for transmitting driving force according to the present invention.
Referring to fig. 1 to 3, a safety cover 11 is provided at the top of a main body 10 of the dryer, thereby forming the outside of the dryer. A door is provided at one side of the main body 10 of the dryer for putting laundry into the dryer. A rotatable drum 20 is provided in the main body 10 of the dryer so as to receive wet laundry and dry it.
The drum 20 is rotatably supported inside the main body 10 of the dryer. The drum 20 having a cylindrical shape is connected to a driving motor 40 provided at the bottom of the dryer through a driving force transmission belt 30 to be rotated by receiving a driving force caused by the rotation of the driving motor 40. Pulley 50 is screw-coupled to rotary shaft 41 of drive motor 40; the drum 20 is rotated by the operation of the drive force transmission belt 30, the drive force transmission belt 30 being passed through an idle pulley 50A selectively installed to surround the drum 20, the drive force transmission belt 30 being engaged with the pulley 50.
Fig. 4 is an exploded perspective view showing a pulley assembly for transmitting a driving force according to the present invention. Fig. 5 is a cross-sectional view taken along the rotation axis direction showing a pulley assembly for transmitting driving force according to the present invention. Fig. 6 is a cross-sectional view showing a pulley guide in a pulley assembly for transmitting driving force according to the present invention.
As shown in fig. 4 to 6, the pulley 50 engaged with the driving force transmission belt 30 for rotating the drum 20 includes: pulley body 51, hub 52, first locking ring 53 and second locking ring 54. The hub 52 is provided at the center of the pulley body 51, and is coupled to the rotation shaft 41 of the driving motor 40 so as to be clamped by the driving force transmission belt 30. The first locking ring 53 and the second locking ring 54 are formed at both ends of the hub 52, respectively, and are formed to have a diameter larger than that of the hub 52. A curved inclined surface 53A is formed on the inner side surface of the first locking ring 53. An inclined surface 54A is formed on an inner side surface of the second locking ring 54. The circumference of the second locking ring 54 is formed in a nut shape so as to facilitate work using a power wrench (spanner) or the like when coupling the pulley 50 to the rotation shaft 41.
The screw 55 is formed along the circumferential surface of a hole penetrating a rotation shaft passing through the center of the pulley body 51, and the screw 41A is formed at one end of the rotation shaft 41. Accordingly, the pulley 50 is coupled to the rotation shaft 41. A pulley guide 60 coupled to the rotation shaft 41 is installed at one side of the first locking ring 53 of the pulley 50 adjacent to the pulley 50.
Pulley guide 60 includes: an inner sleeve 61, a stiffener 62, an outer cover 63, contact protrusions 64 and a flat surface 65. An inner sleeve 61 is formed at the center of the pulley guide 60 in the direction of the rotation shaft 41 to surround the rotation shaft 41, and a rotation shaft fitting hole 61A coupled with the rotation shaft 41 is formed in the inner sleeve 61.
The reinforcing members 62 are formed at prescribed intervals along the outer circumference of the inner sleeve 61. The reinforcing member 62 has a structure capable of reducing the amount of material used to form the pulley guide 60 and reinforcing the strength of the housing 63 integrally formed with the reinforcing member 62. The contact protrusions 64 are protruded at predetermined intervals along the inner circumference of the inner sleeve 61. The flat surface 65 allows the mating hole 61A of the inner sleeve 61 to be cut into a D-shape. The pulley guide 60 is coupled with the rotation shaft 41 such that the flat surface 65 of the pulley guide 60 and the cut surface 41B of the rotation shaft 41 are in surface contact with each other.
The housing 63 has an inclined surface 63A that gradually becomes lower toward the pulley 50. The curved inclined surface 53A of the pulley 50 contacts the inclined surface 63A of the housing 63 to form a continuous inclined surface. The curved inclined surface 53A and the inclined surface 63A gradually become higher from the first locking ring 5 of the pulley main body 51 toward the driving motor 40. Accordingly, the curved inclined surface 53A of the first locking ring 53 and the inclined surface 63A of the housing 63 are connected to have a continuous circumferential surface as a whole, thereby preventing the driving force transmission belt 30 from moving toward the driving motor 40.
In other words, when the driving motor 40 is operated, the rotation shaft 41, which rotates accordingly, rotates together with the pulley 50 and the pulley guide 60. When driving force is transmitted to the drum 20 by the driving force transmission belt 30 running on the hub 52 at the center of the pulley main body 51, the driving force transmission belt 30 may be moved in the direction of the first locking ring 53 of the pulley 50 by vibration driven by the drum 20. In this case, the driving force transmission belt 30 can continuously maintain its correct position in the hub 52 at the center of the pulley main body 51 while sliding along the curved inclined surface 53A of the first locking ring 53 and the inclined surface 63A of the outer cover 63 of the pulley guide 60. Accordingly, the derailment of the driving force transmission belt 30 is prevented, and accordingly, the driving force transmission belt 30 can safely transmit the driving force to the drum 20, thereby preventing a safety accident that may occur when the drum 20 is stopped due to the derailment of the driving force transmission belt 30.
Fig. 7 is a cross-sectional view taken along the rotation axis direction showing still another embodiment of the second locking ring 54 of the pulley assembly for transmitting driving force according to the present invention. As shown in fig. 7, the circumferential diameter of the second locking ring 54 may be equal to or greater than the circumferential diameter of the first locking ring 53. This structure can positively prevent the driving force transmission belt 30 from moving in the outer direction of the second lock ring 54 when the drum 20 is operated.
Fig. 8 is a perspective view showing still another embodiment of a pulley guide 60 in a pulley assembly for transmitting driving force according to the present invention. Fig. 9 is an exploded perspective view, and fig. 10 is a cross-sectional view thereof. The pulley assembly for transmitting driving force according to the present invention forms firm mutual coupling between the screw thread 55 and the screw thread 41A, the screw thread 55 being formed along the circumferential surface of the rotation shaft fitting hole formed through the pulley body 51, the screw thread 41A being formed on the rotation shaft 41.
Referring to fig. 8 to 10, the contact protrusions 64 may protrude at regular intervals along the inner circumference of the inner sleeve 61 of the pulley guide 60. The contact protrusion 64 and the rotation shaft 41 are fitted to each other, and at the same time, the contact protrusion 64 is in surface contact with the circumferential surface of the rotation shaft 41 to form a firm coupling.
Also, in the case where the pulley guide 60 is provided by injection molding using a synthetic resin material, since the rotational shaft 41 made of metal and the pulley guide 60 made of a synthetic resin material have different hardness, coupling force (coupling force) is improved by press-fitting the pulley guide along the circumferential surface of the rotational shaft 41 via the contact protrusion 64, so that the present invention can prevent the rotational shaft 41 and the pulley guide 60 from idling (running idle).
In addition, since the flat surface 65 of the pulley guide 60 and the cutting surface 41B of the rotary shaft 41 are kept in surface contact with each other, as shown in fig. 6, when the rotary shaft 41 rotates, sliding is prevented by the angle portions at both ends of the flat surface 65 and the cutting surface 41B of the rotary shaft 41, thereby forming a more firm coupling. Accordingly, it is possible to prevent the idle running of the pulley guide 60 when the driving force transmission belt 30 running on the hub 52 at the center of the pulley body 51 rotates.
Meanwhile, as shown in fig. 8 to 10, the cutting surface 65 in fig. 6 may be formed as a convex mating surface 66 of a circular arc shape. That is, the convex fitting surface 66 may be formed along one side of the inner circumference of the inner sleeve 61 of the pulley guide 60, and the convex fitting surface 66 of the pulley guide 60 and the cutting surface 41B of the rotary shaft 41 may be coupled by press-fitting, thereby allowing the pulley guide 60 to be more firmly coupled to the rotary shaft 41.
Fig. 11 is a cross-sectional view showing another embodiment of a pulley guide 60 in a pulley assembly for transmitting driving force according to the present invention. Fig. 12 is a cross-sectional view showing yet another embodiment of a pulley guide 60.
The pulley guide 60 shown in fig. 11 is another embodiment in which the magnet M is formed by injection molding on the inside of a flat surface 65 formed along one side of the inner circumference of the inner sleeve 61, and the pulley guide 60 shown in fig. 12 is yet another embodiment in which the magnet M is formed by injection molding on the inside of a convex mating surface 66 along one side of the inner circumference of the inner sleeve 61. According to other embodiments of the present invention shown in fig. 11 and 12, the magnet M in the flat surface 65 or the magnet M in the convex mating surface 66 is attached to the rotating shaft 41 as a metal magnet by magnetic force with the pulley guide 60 and the rotating shaft 41 mated with each other, thereby increasing the coupling force between the pulley guide 60 and the rotating shaft 41.
The detailed description of the invention as set forth above is merely illustrative for an understanding of the invention and is not intended to limit the scope of the invention. The scope of the invention is defined by the appended claims. Furthermore, simple modifications or variations of the invention should be construed as falling within the scope of the invention.
