The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
The utility model embodiment provides a kind of roller washing machine, below roller washing machine that the utility model embodiment is provided be specifically introduced:
Fig. 1 is the structural representation according to the washing machine of the utility model embodiment, and as shown in Figure 1, the washing machine of this embodiment comprises inner core axle 10, clutch shaft bearing 20, the second bearing 30, noise reduction packing ring 40, urceolus rear flange 50 and bearing block 60.
Particularly, inner core axle 10 is the stairstepping rotating shaft that comprises the first end difference and the second end difference, wherein, the first end difference is with respect to the inside of the close inner tank of washing machine of the second end difference, the relative phase I of the second end difference, section was away from the inside of washing machine, the diameter of the first end difference all is formed with the backstop end face greater than the diameter of the second end difference on the first end difference and the second end difference; Clutch shaft bearing 20 is set on the inner core axle 10, and matches with the first end difference; The second bearing 30 is set on the inner core axle 10, and matches with the second end difference; Noise reduction packing ring 40 is arranged between the backstop end face of the second bearing 30 and the second end difference; Bearing block 60 is arranged on the urceolus rear flange 50, and bearing block 60 has the stairstepping through hole, and wherein, the stairstepping through hole in inner core axle 10, clutch shaft bearing 20 and the second bearing 30 and the bearing block matches, and forms the oil sealing chamber between the second bearing 30 and the bearing block.
The operation principle of the roller washing machine that provides in conjunction with the utility model embodiment illustrates the beneficial effect that the utility model embodiment reaches: inner core axle 10 supports the revolution of other movement parts motors, be connected with the frame urceolus rear flange 50 of machine by bearing again simultaneously, inner core axle 10 connects direct driving motor away from an end of inner tank of washing machine, and inner core axle 10 connects inner core near an end of inner tank of washing machine.Inner core axle 10 utilizes respectively the backstop end face (also cry and support axle journal) of the first end difference and the second end difference to support clutch shaft bearing 20 and the second bearing 30, and relies on the rotation of motor to drive inner cylinder rotating.
The engage journal of inner core axle (axle journal of assembling driving member) is the generally requirement of relative-position error between inner core axle and bearing with respect to the axiality of back shaft collar.As the precise part of washing machine, the quality of fit of inner core axle is generally 0.001 ~ 0.005 to the radial run-out that supports axle journal.If the rotating speed of washing machine is too high, be that motor is realized high-frequency rotating, the inner core axle is subjected to Moment, produces symmetry circulating stress (top tension, neutral line stress is zero, the bottom is compression), behind the long time running, inner core axle 10 can reduce with respect to the axiality between bearing, quality of fit also can strengthen the radial run-out that supports axle journal, thereby the phenomenon of generation axle vibration, cooperate the generation gap with the second bearing 30, cause both because friction produces noise.
The washing machine of the utility model embodiment is by arranging the noise reduction packing ring between the backstop end face of the second bearing 30 and inner core axle 10; take axial location as main; bear the axial load that bearing produces; apply prestressing force to bearing; reduce the noise of bearing operation, improve running accuracy and the stationarity of bearing, can better protect bearing; prolong the service life of bearing, reduce the noise of product.Specifically, when inner tank of washing machine rotates, the counteracting of noise reduction packing ring or buffering inner cylinder rotating and motor dither bring the inertia of vibration to the inner core axle, adjusted the offset of inner barrel of washing, it is minimum that off-centre is dropped to, can make vibration of washing machine reduce 0.3-0.8 doubly, and then reach the effect that reduces the washing machine operating noise.
Preferably, noise reduction packing ring 40 comprises: wave washer and plain washer, wave washer are arranged on the side near the second bearing 30, and plain washer is arranged on the side near the backstop end face of the second end difference.
An important function of wave washer has realized the axial location of bearing exactly, prevents that because the vibration of axle and the friction between the bearing, this is that flat shim is irreplaceable.And adopt the combination of wave washer and plain washer, make exactly the transition that a plane is arranged between each plane of bearing.Say that simply flat shim adds the mode of flat shim, can reach on the thickness, but can not prevent the bearing vibration on the effect; It is also not all right that wave washer adds the mode of wave washer, because their contacts is two planes of end difference and bearing, do not have the way of contact of flatness.So, in the utility model preferred embodiment, by noise reduction packing ring 40 being set to the mode of wave washer and plain washer, realized the operating noise of further reduction washing machine.Simultaneously, because the cost of wave washer and plain washer is lower, also realized reaching with low-cost investing method the effect of the operating noise that lowers washing machine.
Wherein, the front view of wave washer and lateral plan are respectively shown in Fig. 2 a and Fig. 2 b, the thickness H of wave washer is 4.2-4.8mm, and the waviness t of wave washer is 0.35-0.45, and the maximum (top) speed the when external diameter of wave washer and internal diameter can turn round according to laundry machine dehydration is set.In this embodiment, illustrate the setting of the design parameter of wave washer external diameter and internal diameter.When the design maximum rotating speed of washing machine was 1200 rev/mins, outer diameter D that can wave washer was set to 33.2-33.5mm, and the inner diameter d of wave washer is set to 25.2-25.4mm; When the design maximum rotating speed of washing machine was 1400 rev/mins to 1600 rev/mins, outer diameter D that can wave washer was set to 38.2-38.5mm, and the inner diameter d of wave washer is set to 30.2-30.4mm.
The front view of plain washer is shown in Fig. 3 a, and shown in Fig. 3 b, the thickness H of plain washer is 0.9-1.1mm along the cutaway view of A-A direction among Fig. 3 a, and the external diameter of plain washer and internal diameter also can be according to the design maximum speed settings of washing machine.In this embodiment, illustrate the setting of the design parameter of plain washer external diameter and internal diameter, when the design maximum rotating speed of washing machine was 1200 rev/mins, outer diameter D that can plain washer was set to 34-34.1mm, and the inner diameter d of plain washer is set to 25.1-25.2mm; When the design maximum rotating speed of washing machine was 1400 rev/mins to 1600 rev/mins, outer diameter D that can plain washer was set to 39-39.1mm, and the inner diameter d of plain washer is set to 30.2-30.3mm.
The above design of the utility model has realized reducing the operating noise of washing machine, has reached the effect that prolongs the service life of bearing.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
