Abstract
The utility model discloses a washing machine shaft coupling The washing machine shaft coupling comprises an upper contact flange, a lower contact flange and an insulating plate which is arranged between the upper contact flange and the lower contact flange. The contrapuntal mounting holes are broached upon the insulating plate, theupper contact flange and the lower contact flange. In the above-mentioned contrapuntal mounting holes are equipped the insulating bushes in which the bolts and the nuts are put, fixing and connecting. The utility model is applied to the various washing machines. Its key function is to provide the rigid fixation, the high reliable insulation, and to improve the motor shaft transmission efficiency.
Description
Technical field
The utility model relates to a kind of shaft coupling, relates in particular to a kind of washing machine shaft coupling.
Background technology
As everyone knows, in the transmission system of washing machine, need to be connected between the output shaft of drive motors and the dehydrating vessel in washing machine axle by shaft coupling.Traditional structure is that the upper/lower terminal at shaft coupling is provided with two circular holes respectively, be inserted in respectively on dehydrating vessel in washing machine axle and the drive motors output shaft, between motor shaft and coupling circular hole, insulation sleeve is set, though such design is simple in structure and can improve security in the washing machine use.But also exist the some shortcomings part:, in the washing machine use, have certain potential safety hazard because washing machine uses for a long time or because the load of shaft coupling is big, cause insulation sleeve loosening easily easily.Reduce insulation effect if strengthen the easy again bursting insulation sleeve of the pressure of trip bolt, and because the existence of this insulation sleeve, the concentricity that shaft coupling is connected with motor shaft also is difficult to guarantee; Produce friction between insulation sleeve and the motor shaft, reduced the transmission efficiency of motor shaft.
Therefore, need to occur a kind of fixed, insulating reliability is high and can improve the washing machine shaft coupling of motor shaft transmission efficiency.
Summary of the invention
The technical problems to be solved in the utility model is the defective that overcomes prior art, provide a kind of fixed, insulating reliability is high and can improve the washing machine shaft coupling of motor shaft transmission efficiency.
The utility model provides a kind of washing machine shaft coupling, comprise adpting flange and following adpting flange, between adpting flange and the following adpting flange insulation board is set on described, on described upper and lower adpting flange and insulation board, offer the contraposition installing hole, in described contraposition installing hole, be provided with insulation sleeve, screw bolt and nut is arranged in the described insulation sleeve, and fixedly connected.
Wherein, the end face that described upward adpting flange is connected with following adpting flange is the plane, and correspondingly, described insulation board is a planar insulator plate.Adpting flange top is provided with the connecting axle that is connected with the clutch coupling of washing machine axle sleeve on described, is provided with the axle sleeve that is connected with the motor for washer axle in the described bottom of adpting flange down.The two ends that are shaft coupling connect motor for washer axle and dehydration barrel axis respectively, make motor shaft to drive the dehydration barrel axis running by shaft coupling, strengthened the fastness that connects, thereby improved safety reliability, and avoided the direct friction of insulation sleeve and motor shaft, improved the transmission efficiency of motor shaft.Simultaneously, improve the concentricity that shaft coupling is connected with motor shaft, further improved the transmission efficiency of motor shaft.
As a kind of improvement of the present utility model, described contraposition installing hole is provided with two or more.Can guarantee the fastness that each parts of shaft coupling are installed.
As a kind of optimal way of the present utility model, the end face that described upper and lower adpting flange is connected for closed smooth curve surround triangular shaped.Preferably be provided with 3 contraposition installing holes on it.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
1, fixed;
2, safety and reliability height;
3, improve the motor shaft transmission efficiency.
Description of drawings
Fig. 1 is the design of part schematic diagram of the utility model washing machine shaft coupling.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-nut; The 2-insulation sleeve; The last adpting flange of 3-; The 4-insulation board; Adpting flange under the 5-; The 6-bolt; 7-contraposition installing hole.
The specific embodiment
As shown in Figure 1, the utility model washing machine shaft coupling comprises adpting flange 3 and following adpting flange 5, between last adpting flange 3 and following adpting flange 5, an insulation board 4 is set, on upper and lower adpting flange 3,5 and insulation board 5, offer contraposition installing hole 7, in the contraposition installing hole 7 of upper and lower adpting flange 3,5, be respectively equipped with insulation sleeve 2, bolt 6 and nut 1 are arranged in the described insulation sleeve 2, and cooperation is fastenedly connected.
Wherein, the end face that last adpting flange 3 is connected with following adpting flange 5 is the plane, and correspondingly, described insulation board 4 is a planar insulator plate.Be provided with the connecting axle that is connected with the clutch coupling of washing machine axle sleeve on last adpting flange 3 tops, be provided with the axle sleeve that is connected with the motor for washer axle in the bottom of following adpting flange 5.The two ends that are shaft coupling connect motor for washer axle and dehydration barrel axis respectively, make motor shaft to drive the dehydration barrel axis running by shaft coupling, motor shaft does not directly contact with insulation sleeve like this, strengthened the fastness that connects, improved security reliability, avoid the direct friction of insulation sleeve and motor shaft, improved the transmission efficiency of motor shaft.Simultaneously, improve the concentricity that shaft coupling is connected with motor shaft, and then improved the transmission efficiency of motor shaft.
Contraposition installing hole 7 is provided with two or more, can guarantee the fastness that each parts of shaft coupling are installed.The end face that upper and lower adpting flange 3,5 is connected for closed smooth curve surround triangular shaped.Preferably be provided with 3 contraposition installing holes on it.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
