PatXML 1/9 BB1646-7.818
Description DRYER DRUM SUPPORT ROLLER
[0001] The present invention relates to a dryer that comprises a drum, the front bearing of which is performed by means of rollers.
[0002] In dryers, the drum wherein the laundry to be dried is loaded, is rotated by a motor and thus, the drying process is performed. In the state of the art, the drum is borne inside the dryer body at its front side wherein the laundry intake opening is located by means of sliding or roller mechanisms. The circular portion of the drum extending to its front side is used for bearing. Roller mechanisms are preferred for supporting the drum since they are less dependent on the surface smoothness of the drum, and two rollers, at the centers of which bearings are situated, are disposed generally under the drum. In the state of the art, the roller shaft (M) which is inserted to the center of the roller (T) and which provides the roller (T) to be connected to a point in a rotatable manner is mounted to the hub of the bearing (R) that is at the center of the roller (T) by press-fit (Figure 1). In order that the roller shaft (M) can be mounted by press-fit and at the same time, without damaging the bearing (R), the roller shaft (M) has to be processed with fine tolerances, and if the press-fit diameter of the shaft (M) exceeds the tolerances, the life-span of the bearing (R) is shortened while the dryer is still in the manufacturing phase, and in case of malfunction, component replacements and maintenance costs increase.
[0003] In the dryer explained in the European Patent Document No EP0802273, the drum wherein the laundry is disposed is guided in the vicinity of the intake side by means of rollers. The rollers are rotatably mounted by means of bearing axes in a casing portion surrounding the intake opening.
[0004] The aim of the present invention is the realization of a dryer wherein its rollers that provide the front bearing of the drum are easily assembled and damages against them are prevented.
[0005] The dryer realized in order to attain the aim of the present invention is explicated in the claims.
[0006] The drum of the dryer of the present invention rotates on top of the rollers assembled to a casing which surrounds the laundry intake opening and PatXML 2/9 BB1646-7.818
which is produced from plastic material.
[0007] The rollers are mounted to the casing by being inserted to the sleeves which are produced as a single piece with the casing that provides the drum to be borne from the front side, which have a hollow cylindrical shape, which provide the roller to be assembled to the casing and which, at their center, have a screw hole that extends towards the inside of the casing.
[0008] The sleeve surrounds the screw hole portion opening to the outside of the casing and extends towards the outside of the casing, and has a wall thickness providing the strength that can compensate the forces acting on the roller.
[0009] The sleeve passes through the bearing bore that is at the center of the roller by extending into the roller from the casing, in the direction of the rotational axis of the roller and contacts the cylindrical wall of the bearing bore.
[0010] After being mounted to the sleeve, the roller is fixed in the axial direction by means of a screw which is mounted to the casing by being inserted through the screw hole.
[0011] In the preferred embodiment of the present invention, the dryer roller is borne by the bearing which is integrated to the hub of the roller and which has an outer race located at its outer side, and an inner race located at its inner side. The bearing bore is located at the center of the inner race of the bearing and while the roller is assembled to the casing, the sleeve is seated in the bearing bore that is at the center of the inner race of the bearing.
[0012] In an embodiment of the present invention, the diameter of the head of the screw that provides the roller to be fixed to the casing has a dimension such that the screw head will lean all around against the edge of the inner race of the bearing that is at the center of the roller, and after the screw is mounted, elements such as nut and washer are not additionally needed.
[0013] In another embodiment of the present invention, the diameter of the screw body is variable and the diameter of at least one part of the screw body, which is at the screw head-side of the screw body and which remains PatXML 3/9 BB1646-7.818
inside the sleeve at the end of the assembly of the roller to the casing, is greater than the diameter of the screw hole. Thus, the roller is connected to the casing without the press-fit process to the bearing and such that it will eliminate the disadvantages of press-fit. [0014] The dryer realized in order to attain the aim of the present invention is illustrated in the attached figures, where: [0015] Figure 1 - is the schematic view of a dryer roller, a roller bearing and a roller shaft
[0016] in the prior art before being assembled.
[0017] Figure 2 - is the schematic view of the dryer of the present invention. [0018] Figure 3 - are the cross-sectional views of the casing, the roller and the assembly screw located in the dryer of the present invention [0019] in the situation before being mounted to each other. [0020] Figure 4 - is the cross-sectional view of the roller mounted to the casing by the assembly screw.
[0021] Figure 5 - is the cross-sectional view of detail A in Figure 4. [0022] The elements illustrated in the figures are numbered as follows: [0023] 1 - Dryer [0024] 2 - Drum [0025] 3 - Intake opening [0026] 4 - Casing [0027] 5 - Front wall [0028] 6 - Front support rim [0029] 7 - Bearing bore [0030] 8 - Roller [0031] 9 - Screw hole [0032] 10 - Sleeve [0033] 11 - Screw [0034] 12 - Bearing [0035] 13 - Screw head [0036] 14 - Screw body [0037] The dryer (1) comprises a drum (2) wherein the laundry to be dried is disposed and which is rotated around the horizontal axis (X1), an intake PatXML 4/9 BB1646-7.818
opening (3) which is located at the front side of the drum (2) and which provides the laundry to be loaded, a casing (4) which surrounds the intake opening (3), which is produced from plastic material and which provides the drum (2) to be borne from the front side, a ring-shaped front wall (5) which forms the front surface of the drum (2) body, and a circular front support rim (6) which extends from the inner edge of the front wall (5) towards the intake opening (3).
[0038] The dryer (1), furthermore, comprises one or more rollers (8) which are mounted to the casing (4) inner side facing the drum (2), which support the drum (2) by being seated in the front support rim (6), which have a bearing bore (7) located at the center of the roller (8) and providing it to be borne in a rotatable manner, and which rotate around a rotational axis (X2) parallel to the horizontal axis (X1) of the drum (2) by the effect of the rotational movement of the drum (2).
[0039] The dryer (1) of the present invention comprises one or more sleeves (10)
[0040] - which are integrally moulded with the casing (4),
[0041] - which, at their center, have a screw hole (9) extending towards the inside of the casing (4) concentrically with the bearing bore (7),
[0042] - which, in the direction of the rotational axis (X2) of the roller (8), wrap around the screw hole (9) portion opening from the casing (4) outwards and thus, extend from the casing (4) outwards,
[0043] - whereon the roller (8) is mounted,
[0044] - which have a hollow cylindrical shape and which have an outer diameter dimension (D1) that allow them to pass through the bearing bore (7) by loose-fit prior to assembly.
[0045] The sleeve (10) passes through the bearing bore (7) by extending into the roller (8) from the casing (4) in the direction of the roller (8) axis (X2), and contacts the cylindrical wall of the bearing bore (7).
[0046] The sleeve (10) has a wall thickness providing the strength that can compensate the forces acting on the roller (8).
[0047] The dryer (1), furthermore, comprises a screw (11) which, after the roller (8) is mounted to the sleeve (10), is inserted through the screw hole (9) and assembled to the casing (4) by being screwed, and which fastens the PatXML 5/9 BB1646-7.818
roller (8) in the axial direction and thus, prevents it from being detached from the sleeve (10).
[0048] In the preferred embodiment of the present invention, the dryer (1) comprises a bearing (12) which is integrated to the hub of the roller (8) and which has an outer race (R1) located at its outer side, and an inner race (R2) located at its inner side. The bearing bore (7) is located at the center of the inner race (R2) of the bearing (12) and while the roller (8) is assembled to the casing (4), the sleeve (10) is seated in the bearing bore (7) that is at the center of the inner race (R2) of the bearing (12).
[0049] The drum (2) is supported by two rollers (8) which are located at its underside. The rollers (8) are mounted to the casing (4) by being inserted to two sleeves (10).
[0050] The rollers (8) are screwed to the casing (4) by means of the screws (11) mounted to the screw hole (9) in the sleeves (10) and the assembly of the rollers (8) is completed.
[0051] Press-fit method is not applied in the assembly of the rollers (8) and each roller (8) is assembled by using a single screw (11).
[0052] In an embodiment of the present invention, the screw (11) has a screw head (13) which has a diameter dimension such that the screw head (13) will lean all around against the edge of the bearing (12) inner race (R2), and when the screw (11) is screwed to the casing (4) by being inserted through the screw hole (9) in the sleeve (10), the bearing (12) and hence the roller (8) whereto the bearing (12) is integrated are provided to be fixed in the axial direction and thus, the roller (8) is provided not to be detached from the sleeve (10), and elements such as nut and washer are not additionally needed.
[0053] In another embodiment of the present invention, the screw (11) has a screw body (14), the diameter of which is variable, and in the assembly process, it provides the outer diameter (D1) of the sleeve (10) to be increased. In this embodiment, the diameter (D2) of at least one part of the screw body (14), which is at the screw head (13)-side of the screw body (14) and which remains inside the sleeve (10) at the end of the assembly of the roller (8) to the casing (4), is greater than the diameter (D3) of the PatXML 6/9 BB1646-7.818
screw hole (9).
[0054] In the above mentioned embodiment of the present invention, when the roller (8) assembly is performed by the screw (11) being inserted through the sleeve (10) and screwed to the casing (4), the screw body (14) expands the screw hole (9) and thus, increases the outer diameter (D1) of the sleeve (10), in other words, forces the sleeve (10) to expand inside the inner race (R2) of the bearing (12). The sleeve (10) applies pressure to the inner race (R2) of the bearing (12) from the center outwards in the radial direction and thus, during the operation of the roller (8), the inner race (R2) of the bearing (12) is provided not to rotate by being fixed around the sleeve (10).
[0055] Since the sleeve (10) is produced from plastic material, the flexibility of which is more than metal material, together with the casing (4), when the screw (11) is mounted, the sleeve (10) is expanded from the inside by the screw (11) and thus, applies pressure to the inner race (R2) of the bearing (12). In the embodiment of the present invention, the sleeve (10) is inserted to the inner race (R2) of the bearing (12) without straining the bearing (12) and then, by being expanded by the screw (11), a connection similar to press-fit in the prior art is provided. In the state of the art, during press-fit, the bearings are strained in the axial direction and therefore, their operating life-span is shortened. However, in the embodiment of the present invention, since the initial diameter (D) of the sleeve (10) is equal to or smaller than the inner diameter of the bearing (12) inner race (R2), that is, the inner diameter of the bearing bore (7), the sleeve (10) is inserted to the bearing (12) inner race (R2) without straining the bearing (12) in the axial direction, and after the sleeve (10) is inserted to the bearing (12), the diameter (D) of the sleeve (10) is increased by being expanded by the screw (11), and thus, a connection which performs the function of press-fit and which does not have the disadvantages of press-fit is provided and the operating life of the bearing (12) is increased.
[0056] It is to be understood that the present invention is not limited to the embodiments disclosed above and a person skilled in the art can easily introduce different embodiments. These should be considered within the PatXML 7/9 BB1646-7.818
scope of the protection postulated by the claims of the present invention.
