Abstract
The utility model discloses a kind of clutches for washing machine, including input shaft and clutch shaft, clutch axle sleeve is located on input shaft, first bearing is equipped between clutch shaft axle center hole inner end and input shaft, second bearing is equipped between clutch shaft axle center hole potted ends and input shaft, the second bearing is needle bearing, and the input shaft is equipped with the inner ring that inner ring carrying step is used to install needle bearing, is used to install the outer ring of needle bearing in the clutch shaft equipped with outer ring carrying step；Second bearing close to belt pulley uses needle bearing, the needle roller of needle bearing is line stress, and it is high by quenching intensity, stress is strong, service life is long, and the height of the needle bearing of same price is generally twice of ball bearing, can preferably bear the pulling force of belt pulley driving motor so that washing machine operation is more steady.
Description
Technical field
The utility model is related to washing machine drum states to replace clutch technical field, and washing machine is used for more particularly, to one kind
Clutch.
Background technology
It is washing and dehydration that washing machine, which is generally divided into two states, and the switching of state is completed by clutch.Existing clutch
Device includes belt pulley 1, input shaft 2, clutch shaft 3 and spline housing 4 as shown in Figure 1, and clutch shaft 3 is set on input shaft 2, clutch shaft
Oiliness bearing 5 is designed between 3 axle center hole both ends and input shaft 2, spline housing 4 is encapsulated between outboard bearing and belt pulley 1
On input shaft 2.This clutch in use, on the one hand since 1 stress of belt pulley is always biased into driving motor, to side
Compressing, on the other hand since oiliness bearing 5 is made for metal powder and Porous, insufficient strength is high, therefore in dehydration high speed
Under operating, a lateral wearing of its deviation driving motor of the oiliness bearing 5 of close belt pulley 1 can be bigger, is easily damaged.
To solve this problem, using the height ball bearing identical but larger intensity with oiliness bearing 5 as an alternative,
Although service life is promoted, since ball bearing is point stress, the abrasion deformation of stress point can be bigger, a period of time
Afterwards, the ball of bearing is just no longer mellow and full, causes 2 axis of input shaft to generate deflection so that washing machine tub force unbalance is washed
Washing and being dehydrated can all occur acutely to shake, it would be highly desirable to improve.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to operate steadily, with long service life to be used for washing machine
Clutch.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of clutch for washing machine,
Including input shaft and clutch shaft, clutch axle sleeve is located on input shaft, and first is equipped between clutch shaft axle center hole inner end and input shaft
Bearing is equipped with second bearing between clutch shaft axle center hole potted ends and input shaft；The height of the second bearing is first bearing
1.5 times~2.5 times, the second bearing be needle bearing, the input shaft be equipped with inner ring carrying step for install roll
The inner ring of needle bearing, the interior outer ring for being used to install needle bearing equipped with outer ring carrying step of the clutch shaft.
Preferably, the height of the second bearing is 2 times of first bearing.
Preferably, inner ring carrying step surface is raised in outer ring carrying step surface, have between the two 0.05mm~
The gap of 0.15mm.The friction possibility for reducing spline housing end face and clutch axial end, to promote the efficiency of washing, dehydration.
As an improvement, the height of the needle bearing is more than the step surface of outer ring carrying step to the distance of input shaft end face
0.1mm.So that the friction possibility smaller of spline housing end face and clutch axial end.
Preferably, the needle roller length of the needle bearing is 10mm~13mm.
Compared with prior art, the utility model has the advantage of the second bearings close to belt pulley to use needle bearing,
The needle roller of needle bearing is line stress, and high by quenching intensity, and stress is strong, and service life is long, and the second bearing
Height is 1.5 times~2.5 times of first bearing, can preferably bear the pulling force of belt pulley driving motor so that washing machine is transported
Row is more steady.
Description of the drawings
Fig. 1 uses the schematic cross-sectional view of ball bearing between existing clutch shaft axle center hole both ends and input shaft.
Fig. 2 is the schematic cross-sectional view of the utility model.
Fig. 3 is the enlarged diagram of the utility model input shaft, clutch shaft and spline housing combination structure.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
The present embodiment is illustrated in figure 2 a kind of clutch for washing machine, including belt pulley 11, input shaft 12, clutch
Axis 13 and spline housing 14, other parts do not influence this improvement, are not indicated during I will not elaborate and figure.Clutch shaft 13
It is set on input shaft 12, first bearing 15,13 axle center of clutch shaft is equipped between 13 axle center hole inner end of clutch shaft and input shaft 12
Be equipped with second bearing 16 between hole potted ends and input shaft 12, the spline housing 14 be encapsulated in second bearing 16 and belt pulley 11 it
Between input shaft on；Second bearing 16 is needle bearing, and input shaft 11 is equipped with inner ring carrying step for installing needle bearing
Inner ring, be used to install the outer ring of needle bearing in clutch shaft 13 equipped with outer ring carrying step.The needle roller of needle bearing is by quenching
Fire intensity is high, and what needle roller was born is line stress, and not easy to wear, service life is long, here the height of needle bearing be 13mm~
16mm is 1.5~2.5 times of first bearing 15, and optimal is 2 times, and the needle roller length of needle bearing is preferably 10mm~13mm, is washed
It is longer to wash the bigger needle roller of capacity.
As shown in figure 3, inner ring carrying step surface is raised in outer ring carrying step surface namely inner ring carrying step surface more leans on
Nearly spline housing 14, the gap h1 between inner ring carrying step surface and outer ring carrying step surface is 0.05mm~0.15mm here, excellent
It is selected as 0.1mm.Needle bearing is mounted on input shaft 12 with after clutch shaft 13, and the inner ring of needle bearing is raised in the end of clutch shaft 13
Face so that spline housing 14 is detached with clutch shaft 13, reduces spline housing 14 and 13 contact probability of clutch shaft namely turn of input shaft 12
It is dynamic to be not easy to be transmitted to clutch shaft 13 from spline housing 14, to improve washing and dehydrating effect, but can guarantee clutch shaft 13 not with it is defeated
Enter the disengaging of axis 12.
As an improvement, the height of needle bearing be more than outer ring carrying step step surface to input shaft end face distance, two
Person's gap h2 is preferably 0.1mm so that the outer ring of needle bearing also dimpling in the end face of clutch shaft 13 so that spline housing 14 is more
Far from clutch shaft 13.
