Set up a thrust ball bearing between bearing and sun gear, can be effectual the wearing and tearing of reduction bearing terminal surface, guarantee washing machine transmissions's normal use.
Description
Technical field
The utility model relates to clutch shaft in a kind of power transmission apparatus of washing machines and transmission shaft component.
Background technology
At present at use power transmission apparatus of washing machines, comprise clutch shaft and power transmission shaft, clutch shaft coordinates by being located at bearing-transmission between them with power transmission shaft, and power transmission shaft is also in transmission connection mutually with sun gear, and sun gear end face and bearing face abut against.In washing machine running, bearing needs to bear axial compressive force, and the end face of bearing is easy to be worn, particularly jumbo washing machine, directly affects the service life of power transmission apparatus of washing machines.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide clutch shaft in a kind of power transmission apparatus of washing machines and transmission shaft component, can protect the axial end of bearing, ensures the normal use of power transmission apparatus of washing machines.
To achieve these goals, clutch shaft in a kind of power transmission apparatus of washing machines designed by the utility model and transmission shaft component, comprise clutch shaft and power transmission shaft, bearing is provided with between described clutch shaft and power transmission shaft, described power transmission shaft one end is connected with sun gear, also be provided with thrust ball bearing between described sun gear and bearing, this thrust ball bearing is set on power transmission shaft, and thrust ball bearing outer ring and clutch shaft inwall abut against.
Further, described clutch shaft is arranged with first ring connected in star and the second annular groove near sun gear one end, described first ring connected in star and the second annular groove coaxially arrange and this first ring connected in star than the second annular groove near sun gear, the radius of described first ring connected in star is greater than the radius of the second annular groove, and described thrust ball bearing outer ring and the second annular groove inwall abut against.
Further, described bearing extends to the second annular groove inwall near thrust ball bearing one end thus forms ennation, and this ennation and thrust ball bearing abut against.
Further, a fixed gap is left between described ennation and the second annular groove inwall.
Further, described bearing and ennation one-body molded.
Further, described clutch shaft is provided with groove away from sun gear one end, and the power transmission shaft that described groove is corresponding is arranged with rolling bearing, and this housing washer and groove inner wall abut against.
Further, described power transmission shaft is also arranged with annular water seal outward, and this annular water seal outer ring and clutch shaft inwall abut against, described annular water seal than bearing away from sun gear.
Further, described bearing is oiliness bearing.
Clutch shaft in a kind of power transmission apparatus of washing machines that the utility model obtains and transmission shaft component, its technique effect is: between bearing and sun gear, 1, arrange a thrust ball bearing, the wearing and tearing of bearing face can be effectively reduced, ensure the normal use of power transmission apparatus of washing machines; 2, thrust ball bearing does not abut against with first ring connected in star, thus the grease that in transmission device, brake disc overflows can be made to flow in thrust ball bearing, plays lubrication, extend the service life of thrust ball bearing to thrust ball bearing; 3, between power transmission shaft and clutch shaft, be provided with annular water seal, effectively can prevent the grease in transmission device from overflowing transmission device, thus make the degree of lubrication that transmission device keeps certain, the service life of transmission device can be extended; 4, rolling bearing is set in groove, the wearing and tearing of power transmission shaft periphery can be reduced, thus different sound when decreasing washing of drum type washing machine, add the service life of washing machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, clutch shaft in a kind of power transmission apparatus of washing machines that the utility model provides and transmission shaft component, comprise clutch shaft 1 and power transmission shaft 2, bearing 3 is provided with between clutch shaft and power transmission shaft, be oiliness bearing in the present embodiment, power transmission shaft one end is connected with sun gear 4, is provided with thrust ball bearing 5 between sun gear and bearing, thrust ball bearing is set on power transmission shaft, and thrust ball bearing outer ring and clutch shaft inwall abut against.
Clutch shaft 1 is arranged with first ring connected in star 6 and the second annular groove 7 near sun gear 4 one end, first ring connected in star and the second annular groove coaxially arrange and first ring connected in star than the second annular groove near sun gear, the radius of first ring connected in star is greater than the radius of the second annular groove, and thrust ball bearing outer ring and the second annular groove inwall abut against.Radius due to the second annular groove is greater than the radius of the second annular groove, thrust ball bearing outer ring and the second annular groove inwall abut against, thus thrust ball bearing outer ring is not abutted against with first ring connected in star, the grease that the brake disc in transmission device overflows can be made to flow in thrust ball bearing, lubrication is played to thrust ball bearing, extends the service life of thrust ball bearing.
Bearing 3 extends to the second annular groove 7 inwall near thrust ball bearing 5 one end thus forms ennation 8, this ennation and thrust ball bearing abut against, a fixed gap is left between ennation and the second annular groove inwall, ennation 8 is set, the transmission be conducive between power transmission shaft with clutch shaft coordinates, in washing machine running, reduce moving axially between power transmission shaft and clutch shaft.In order to improve the service life of bearing, bearing 3 is one-body molded with ennation 8.
In order to reduce the wearing and tearing of power transmission shaft 2 periphery, and the different sound caused during power transmission shaft wearing and tearing, clutch shaft is provided with groove away from sun gear one end, and the power transmission shaft that groove is corresponding is arranged with rolling bearing 9, and this rolling bearing 9 outer ring and groove inner wall abut against.
In order to ensure the service life of transmission device, power transmission shaft is also arranged with annular water seal 10 outward, this annular water seal outer ring and clutch shaft inwall abut against, annular water seal than bearing away from sun gear, in the present embodiment, annular water seal 10 is between bearing 3 and rolling bearing 9, and annular water seal can effectively prevent the grease in transmission device from overflowing, the degree of lubrication making transmission device keep certain, extends its service life.
Clutch shaft in the present embodiment and transmission shaft component, the same prior art of occupation mode, repeats no more.
