Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0051] Before further describing the embodiments of this utility model in detail, the directional terms involved in the embodiments of this utility model, such as "upper part," "lower part," and "side part," are used to refer to... Figure 1 The orientation shown is a reference and does not limit the scope of protection of this utility model.

[0052] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0053] Taking garment processing equipment as an example, current conventional large-capacity garment processing equipment has a load capacity of up to 12kg, an inner drum diameter of 530mm, and a rotation speed of up to 1400r / min. To ensure structural strength, two deep groove ball bearings are typically used for support. During operation, the stator of the DD (Direct Drive) motor is connected to the outer drum of the garment processing equipment, and the rotor is connected to the inner drum via a drive shaft. The outer drum and drive shaft are connected by two deep groove ball bearings for load bearing and transmission. During washing and spin-drying, the inner drum rotates at high speed, and the drive bearings are subjected to gravity and centrifugal force from the eccentric rotation of the load. The inner drum and shaft are equivalent to a cantilever structure. According to force balance and torque balance, the two bearings provide opposing forces to the shaft. The greater the distance between the bearings, the better for force balance. Therefore, the entire drive structure is relatively thick, and the overall depth of the garment processing equipment is relatively large. While meeting the requirements of high load, high speed, and large drum diameter, it cannot simultaneously meet the requirement of ultra-thin design.

[0054] like Figure 1 As shown, this application embodiment provides a driving structure for a clothing processing device, which is applied to a clothing processing device. The clothing processing device includes, for example, a washing machine or a dryer.

[0055] The garment handling equipment includes an inner drum 1 and an outer drum 2. The drive structure includes a drive component, a transmission shaft 4, and a bearing 3. The bearing 3 is mounted on the transmission shaft 4 with a clearance fit. The bearing 3 is located between the outer drum 2 and the inner drum 1. The bearing 3 is a crossed roller bearing, which includes an outer ring, an inner ring, crossed rollers, and a cage for retaining the crossed rollers. The crossed rollers are located between the outer ring and the inner ring of the bearing 3. The outer ring of the bearing 3 is connected to the inner drum 1, and the inner ring of the bearing 3 is connected to the outer drum 2. The first end of the transmission shaft 4 is connected to the drive component, the second end of the transmission shaft 4 is connected to the inner drum 1, and the drive component is connected to the outer drum 2.

[0056] like Figure 1 and Figure 2 As shown, the first end of the drive shaft 4 is the right end of the drive shaft 4, and the second end of the drive shaft 4 is the left end of the drive shaft 4. The bearing 3 and the drive shaft 4 are clearance-fitted; when the drive shaft 4 rotates, the inner ring of the bearing 3 does not rotate, and there is no contact between the drive shaft 4 and the bearing 3. For example, the driving component is a DD motor 5 (composed of a stator 52 and a rotor 51). The first end of the drive shaft 4 is fixedly connected to the rotor 51 of the DD motor 5, and the stator 52 of the DD motor 5 is fixedly mounted on the outer cylinder 2 with screws. This embodiment uses a single crossed roller bearing instead of two deep groove ball bearings for transmission between the outer cylinder 2 and the drive shaft 4. Because crossed roller bearings can withstand large radial forces, axial forces, and eccentric bending moments, this embodiment can reduce the thickness of the drive structure while meeting the requirements of high load, high speed, and large cylinder diameter. Compared to the two deep groove ball bearing scheme, it can reduce the thickness of the drive mechanism by approximately 40mm, meeting the ultra-thin requirement. Furthermore, the installation method of the crossed roller bearing eliminates the need for precise shaft-hole fit, reducing processing costs and assembly requirements. Moreover, by connecting the inner cylinder 1 to the drive shaft 4 and the outer ring of the bearing 3, the load of the inner cylinder 1 is distributed to the drive shaft 4 and the bearing 3, enhancing the load-bearing capacity of the drive structure.

[0057] Furthermore, the connection method of connecting the outer ring of bearing 3 to the inner cylinder 1 and the inner ring of bearing 3 to the outer cylinder 2 is easier to be compatible with existing designs compared to the connection of the inner ring of bearing 3 to the inner cylinder 1.

[0058] For example, bearing 3 meets at least one of the following conditions: Condition 1: The inner diameter of the crossed roller bearing is 30-40mm; the outer diameter of the crossed roller bearing is 90-100mm; Condition 2: The thickness of the crossed roller bearing is 13-17mm; Condition 3: The load capacity of the crossed roller bearing is greater than 17000N. The dimensions of the selected bearing 3 match the dimensions of the inner and outer cylinders, for example, the inner diameter of the crossed roller bearing is 35mm, the outer diameter is 95mm, and the thickness is 15mm. The load capacity of the crossed roller bearing can be measured by the rated dynamic load or the rated static load. For example, the rated dynamic load of the selected bearing 3 is greater than 17000N, for example, 17300N, and the rated static load is greater than 20000N, for example, 20900N, which far exceeds the rated load of deep groove ball bearings in conventional designs, so its strength design can meet the requirements of high load, high speed, and large eccentricity.

[0059] For example, such as Figure 1 As shown, a tripod 10 is provided on the inner cylinder 1, and the tripod 10 is set on the surface of the bottom of the inner cylinder 1 facing the outer cylinder 2. The outer ring of the bearing 3 is fixedly connected to the tripod 10, and the second end of the drive shaft is fixedly connected to the tripod 10. The tripod 10 connects the inner cylinder 1, the bearing 3, and the drive shaft 4, increasing the contact area between the bearing 3, the drive shaft 4, and the inner cylinder 1, dispersing the load acting on the inner cylinder 1, and improving operational safety.

[0060] For example, such as Figure 2 As shown, the outer ring of bearing 3 has a first connecting hole 31, and the surface of tripod 10 facing outer cylinder 2 has a first mating hole. The first connecting hole 31 and the first mating hole are arranged in a one-to-one correspondence. The first fastener 6A is inserted into the first connecting hole 31 and the first mating hole to connect the outer ring of bearing 3 and tripod 10. The inner ring of bearing 3 has a second connecting hole 32, and the outer cylinder 2 has a second mating hole. The second connecting hole 32 and the second mating hole are arranged in a one-to-one correspondence. The second fastener 6B is inserted into the second connecting hole 32 and the second mating hole to connect bearing 3 and outer cylinder 2.

[0061] For example, such as Figure 3As shown, in this embodiment, the inner ring of the bearing has eight M4 threaded holes 32 evenly distributed for installation. The outer ring has eight φ4.5 through holes 31 evenly distributed for installation. The triangular bracket 10 has eight M4 threaded holes. A first mating hole (screw) is provided on the triangular bracket 10. The outer ring of the bearing 3 is fixed to the triangular bracket 10 on the inner cylinder 1 using a first fastener 6A. The outer cylinder 2 has a second mating hole, which is a smooth hole corresponding to the second connecting hole 32 on the inner ring of the crossed roller bearing. A second fastener 6B (screw) is used to fix the inner ring of the bearing 3 to the outer cylinder 2. During the fixing of the inner cylinder 1 and outer cylinder 2 to the bearing 3, there are no special hole-shaft matings, making the machining and assembly of the parts very convenient. The crossed roller bearing also has an oil hole 33 for adding lubricating oil.

[0062] like Figure 1 As shown, for example, the tripod 10 has a bearing hole 8 on its surface facing the outer cylinder 2, and a bearing 3 is disposed in the bearing hole 8. The outer ring of the bearing 3 is fixedly connected to the bottom of the bearing hole 8. Specifically, the bearing hole 8 is recessed away from the outer cylinder 2, and a first mating hole is disposed at the bottom of the bearing hole 8. The bearing hole 8 can be integrally formed with the tripod 10, or the tripod 10 can be a separate structure connected by welding or other methods.

[0063] For example, the drive structure also includes a sealing structure 9, which is disposed between the outer cylinder 2 and the tripod 10. The sealing structure 9 is an oil seal, preventing water from entering the drive shaft 4 and the bearing 3.

[0064] For example, a first limiting ring 21 is provided on the bottom surface of the outer cylinder 2 facing the inner cylinder 1. The first limiting ring 21 is located on the outer periphery of the bearing hole 8 in the circumferential direction and extends towards the inner cylinder 1. The bearing hole 8 extends towards the outer cylinder 2. The first limiting ring 21 and the tripod 10 are clearance-fitted, and the bearing hole 8 and the outer cylinder 2 are clearance-fitted to prevent interference between the tripod 10, the outer cylinder 2, and the bearing hole 8 when the inner cylinder 1 rotates.

[0065] The tripod 10 also includes a bore wall 81 of the bearing bore 8, which extends towards the outer cylinder 2; the first limiting ring 21 is located circumferentially on the outer periphery of the bore wall 81. A sealing structure 9 is fitted onto the bore wall 81 of the bearing bore 8, and in the radial direction, the sealing structure 9 is located between the bore wall 81 of the bearing bore 8 and the first limiting ring 21. Figure 1 and Figure 2 As shown, the sealing structure 9 is located between the bore wall 81 of the bearing hole 8, the first limiting ring 21, and the tripod 10.

[0066] For example, such as Figure 1 and Figure 2As shown, a drive shaft mounting hole is provided at the center of the bottom of the bearing hole 8; the drive shaft 4 is disposed in the drive shaft mounting hole. The drive shaft 4 passes through the drive shaft mounting hole and is connected to the tripod 10. There is a clearance fit between the drive shaft 4 and the drive shaft mounting hole.

[0067] For example, such as Figure 2 As shown, a countersunk hole 81 is provided at the bottom of the bearing hole 8. The diameter of the countersunk hole 81 matches the diameter of the inner ring of the bearing 3 to ensure a clearance fit between the bearing hole 8 and the inner ring of the bearing 3. Specifically, the diameter of the countersunk hole 81 is equal to or slightly larger than the diameter of the inner ring of the bearing 3 to prevent the inner ring of the bearing 3 from colliding with the tripod 10 when the inner cylinder 1 rotates.

[0068] For example, such as Figure 2 and Figure 4 As shown, the bottom of the outer cylinder 2 has a first through hole; the drive structure also includes a bearing seat 7, which is fixedly connected to the outer cylinder 2 by bolts; the bearing seat 7 includes a connecting part 71, which passes through the first through hole, and the inner ring of the bearing 3 is connected to the connecting part 71. Specifically, a second mating hole is provided on the connecting part, and a second fastener 6B is inserted into the second connecting hole 32 and the second mating hole to connect the bearing 3 and the bearing seat 7.

[0069] For example, such as Figure 2 and Figure 4 As shown, the bearing housing 7 also includes a fixing part 72 and an annular groove 73, with the annular groove 73 located radially between the fixing part 72 and the connecting part 71. The fixing part 72 is fixedly connected to the bottom surface of the outer cylinder 2 facing away from the inner cylinder 1 by a third fastener 6C. The bottom of the outer cylinder 2 is also provided with a second limiting ring 22, which is disposed on the bottom surface of the outer cylinder 1 facing the inner cylinder 1, located around the first through hole. The second limiting ring 22 extends away from the inner cylinder 1, and the second limiting ring 22 and the annular groove 73 are inserted into each other. With the second limiting ring 22 and the annular groove 73 inserted into each other, and the fixing part 72 and the outer cylinder 2 fixedly connected by the third fastener 6C, the connection between the bearing housing 7 and the outer cylinder 2 is realized.

[0070] For example, such as Figure 2 and Figure 4 As shown, the diameter of the connecting part 71 matches the diameter of the inner ring of the bearing 3. The connection position between the annular groove 73 and the connecting part 71 is recessed away from the inner cylinder 1 to avoid collision between the outer ring of the bearing 3 and the bearing seat 7 when the inner cylinder 1 rotates.

[0071] For example, embodiments of this disclosure also employ means to further reduce the thickness of the garment handling device, which may include means 1, means 2 or means 3.

[0072] Method 1: A tripod mounting groove is provided on the bottom surface of the inner cylinder 1 facing the outer cylinder 2, and the tripod 10 is installed in the tripod mounting groove. The installation groove allows the depth of the inner cylinder 1 and the thickness of the drive structure to overlap, further reducing the sum of the inner cylinder depth and the drive structure thickness, and further meeting the ultra-thin requirements of the garment processing equipment.

[0073] Method 2: The axial distance between the center of the tripod 10 and the driving component is greater than the axial distance between the outer edge of the tripod 10 and the driving component. In other words, the center of the driving structure protrudes towards the inner cylinder 1. A first through hole is provided at the bottom of the outer cylinder 2, and the axial distance between the center of the first through hole and the driving component is greater than the axial distance between the outer edge of the bottom of the outer cylinder 2 and the driving component. This means the center of the outer cylinder 2 protrudes towards the inner cylinder 1, further reducing the sum of the inner cylinder depth and the driving structure thickness, thus further meeting the ultra-thin requirements of the garment processing equipment.

[0074] Method 3: Use both methods 1 and 2 simultaneously.

[0075] For example, the garment handling device or the driving structure of the garment handling device according to the embodiments of this disclosure also satisfies at least one of the following conditions:

[0076] Condition A: The ratio between the maximum depth of the inner cylinder and the thickness of the drive structure is greater than 2.5; the thickness of the drive structure is the distance between the tripod and the drive component;

[0077] The ratio between the maximum depth of the inner cylinder 1 and the thickness of the drive structure is greater than 2.5. The thickness of the drive structure is the distance between the tripod 10 and the drive component. The depth extension direction of the inner cylinder 1 and the thickness extension direction of the drive structure are both along the axial direction of the inner cylinder 1. For example, if the depth of the inner cylinder 1 is 401 mm and the thickness of the drive structure is 125 mm, the ratio between the depth of the inner cylinder 1 and the thickness of the drive structure is 3.3. The configuration of the depth of the inner cylinder 1 and the thickness of the drive structure can be adjusted according to requirements.

[0078] Condition B: The sum of the maximum depth of the inner cylinder 1 and the thickness of the drive structure is 520mm-540mm.

[0079] Condition C: The load capacity of the garment processing equipment is greater than or equal to 10 kg.

[0080] Condition D: The diameter of inner cylinder 1 is greater than or equal to 520mm.

[0081] Condition E: The rotational speed of inner cylinder 1 is greater than or equal to 1200 r / min.

[0082] For example, the ratio between the maximum depth of the inner drum and the thickness of the drive structure is 3.3, the load capacity of the garment processing device is 12 kg, and the sum of the maximum depth of the inner drum 1 and the thickness of the drive structure is 526 mm. The rotational speed of the inner drum 1 is 1400 r / min. This embodiment also provides a garment processing device with the garment processing device drive structure described above. When using the garment processing device drive structure described above, the inner drum 1 in the garment processing device can be configured to be deeper, increasing the volume of the inner drum 1, which can meet the current demand for garment processing devices with large load, high rotational speed, and large diameter and ultra-thin design.
