The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The said a kind of decelerator for washing machine of the utility model, agent structure comprises housing 1, on housing 1, is provided with output shaft installing sleeve 2, the general and housing 1 of said output shaft installing sleeve 2 is structure as a whole.For output shaft cavity is installed in the said output shaft installing sleeve 2; Output shaft installation cavity is following installation cavity 15 near a side of housing 1; Output shaft installation cavity is last installation cavity 14 away from a side of housing 1, and the diameter of following installation cavity 15 is less than the diameter of last installation cavity 14.In the installation cavity 15 internal axle sleeve 13 is being installed down, reducer output shaft 3 is installed in internal axle sleeve 13, reducer output shaft 3 lower ends are connected with the washing machine PTO, and the upper end is stretched out output shaft installing sleeve 2 and is connected with the agitation wheel for washing machine axis.Water seal circle 12 is installed in last installation cavity 14, and on the boss 16 that installation cavity 15 and last installation cavity 14 had a common boundary under water seal circle 12 was positioned at, water seal circle 12 can prevent to cause damage in water inflow reductor and the motor.On water seal circle 12, place first pad 10 and second pad 5.Output shaft jump ring groove 8 is set on the said reducer output shaft 3, output shaft jump ring 4 is installed on output shaft jump ring groove 8, output shaft jump ring 4 is between first pad 10 and second pad 5.Fixedly jump ring groove 6 is set on output shaft installing sleeve 2 inwalls, fixedly installs and fixes jump ring 7 in the jump ring groove 6.Fixedly jump ring 7 is positioned at the top of first pad 10 and second pad 5.Utilization fixedly jump ring 7 is fixed on first pad 10 and second pad 5 in the installation cavity 14, thereby output shaft jump ring 4 vertical fixing are lived, and prevents reducer output shaft 3 purpose of play in vertical direction to reach.The said technology of the utility model when installation and removal reducer output shaft 3, need not to open housing 1, only need unclamp the installation and removal that fixing jump ring 7 can be realized reducer output shaft 3, and is very easy to use, is convenient to safeguard.
The utility model is further characterized in that: in order to prevent the pad water seal circle 12 that rubs in use; Cause water seal circle 12 to damage and cause and leak; Antifriction boss 11 preferably is set in last installation cavity 14, and said antifriction boss 11 is between water seal circle 12 and pad.The height of antifriction boss 11 protrusions is generally between 1mm-2mm; The water seal circle installation cavity diameter that antifriction boss 11 forms is less than last installation cavity 14 diameters at place, pad installation site; Water seal circle 12 is installed in this position; And water seal circle 12 upper surfaces are lower than antifriction boss 11 upper surfaces, and pad then is installed on the antifriction boss 11.When normal the use, water seal circle 12 can not receive the wearing and tearing of pad, has improved the service life and the reliability of the utility model greatly.
In the utility model; Because the model of agitation wheel for washing machine is different; Therefore the height of its needed reducer output shaft 3 is also different; In order to make the said reducer output shaft 3 of the utility model can adapt to the different height requirement, preferably adopt adjustable for height reducer output shaft 3, its concrete embodiment has following two kinds:
The structure of one of embodiment is: the thickness of said first pad 10 is preferably inequality with the thickness of second pad 5.Adopt first pad 10 and second pad 5 of different-thickness, can select different installation sites according to the desired height requirement.For example: when the lower reducer output shaft of needs 3 height, can thin pad be placed on output shaft jump ring 4 bottoms, thicker pad is placed on output shaft jump ring 4 tops; When the higher reducer output shaft of needs 3 height, can thicker pad be placed on output shaft jump ring 4 bottoms, the pad that will approach be placed on output shaft jump ring 4 tops.The advantage of this embodiment is: simple for structure, easy to adjust, cost is low.
Embodiment two structures be: between first pad 10 and second pad 5, be provided with at least one and regulate pad 9.The ability instance can be positioned at the quantity of the adjusting pad 9 of output shaft jump ring 4 bottoms through adjustment, regulates the height of reducer output shaft 3.To regulate pads 9 is example to be provided with three, when needs when needing lower reducer output shaft 3 height, can 0 or 1 adjusting pad 9 be placed into output shaft jump ring 4 bottoms, residual accommodation pad 9 is placed into output shaft jump ring 4 tops; When the higher reducer output shaft of needs 3 height, can regulate pads 9 with 2 or 3 and be placed into output shaft jump ring 4 bottoms, residual accommodation pad 9 is placed into output shaft jump ring 4 tops.The present embodiment regulative mode is various, and precision is high, and is applied widely.
Above-mentioned various height adjuster all through setting the fixedly jump ring groove 6 of mated position relative with it, and installs and fixes jump ring 7 it is fixedly secured in vertical direction in fixing jump ring groove 6.
Install for ease and fixing internal axle sleeve 13, said internal axle sleeve 13 bottoms preferably are provided with evagination collar 17, and the diameter of evagination collar 17 is greater than the cavity diameter of installation cavity 15 down.Present embodiment is fixed for adopting the mode that internal axle sleeve 13 is installed from the bottom to carry out internal axle sleeve 13, is convenient to internal axle sleeve 13 cooperate with transmission device, prevents that internal axle sleeve 13 from coming off, and improves the utility model fastness.
The utility model in use; Impeller output shaft height according to washing machine; Select suitable reducer output shaft 3 height; And the quantity or the position of adjusting first pad 10 and second pad 5 that are positioned at the adjusting pad 9 of output shaft jump ring 4 bottoms through adjustment adjust reducer output shaft 3 highly, thereby said decelerator of the utility model and impeller output shaft are used.
