Abstract
The invention discloses a locking device of washing machine rotation axis, and relates to the technical field of speed reduction clutch of a washing machine. The locking device overcomes the insufficiencies of clamp-ring type locking device in complicated assembly, diseconomy, and uncontrollability of axial clearance. The locking device comprises a body portion, and is characterized by that double wedges are arranged outwards on the body portion in an equally distributed mode, a round of grooves are arranged on the joint of the double wedges and the body portion; the double wedges are in square shape, and the edge of the outer portion of the double wedges are all arranged on a circumference which shares one center with the double wedges; the corner portions of the double edges are provided with circular angles, and the breadths of the double wedges should be smaller or equal to the distance between every two adjacent double edges. The locking device of washing machine rotation axis is ingenious in design, easy to carry; meanwhile the locking device of washing machine rotation axis has larger pulling strength and better spacing effect. The locking device of washing machine rotation axis has the advantages of being light in quality, low in cost and convenient for production.
Description
Technical field
The present invention relates to decelerating clutch of washing machine technical field, particularly to the locking device of decelerating clutch of washing machine rotary shaft.
Background technology
The rotary shaft of existing pulsator washing machine has wash shaft and dehydrating shaft，Dehydrating shaft is to be press-fitted with bearing inner race interference to fixedly mount when mounted，Wash shaft mainly pass through bushing radially defined in dehydrating shaft，Mainly it is pressed in by the step of evagination in axial direction and block on the step of convex of dehydrating shaft，Then the other end jump ring that wash shaft passes from dehydrating shaft is blocked，This assembling mode by jump ring axial lock，Wash shaft is difficult pull-out from dehydrating shaft，Safety，But the specified channel installing jump ring must be machined with wash shaft，Increased manufacturing procedure，During assembling，Loaded with special Circlip tongs，Axial gap needs to adjust by the copper backing of different-thickness，And cause correlated parts follow-up assembling mode single，And it is non-dismountable，Encounter when having unfavorable condition，Can only be done over again by way of destroying，Not only cumbersome，And it is very uneconomical.
Has plenty of the locking device with positioning sleeve, this assembling mode, easy to assembly, but axial gap control is more difficult, because the normal common plasticses of positioning sleeve are processed by mould, during mould processing, shrinkage ratio is difficult to control to, and causes the concentric flatness of the external diameter of positioning sleeve to be difficult to meet requirement, causes and wash shaft loads in dehydrating shaft, easily pull out, that is, pulling-out force is difficult to meet and requires.
Content of the invention
The purpose of the present invention is: provides a kind of locking device of washing machine rotary shaft, to overcome drawbacks described above.
According to above-mentioned purpose, the basic technical scheme of the present invention is: a kind of locking device of washing machine rotary shaft, including body it is characterised in that: described body is provided with outwards equally distributed double wedge, and described double wedge is provided with a circle groove with the junction of body.
Further technical scheme is that described double wedge is square.
Further technical scheme is that the edge of the described outer end of double wedge is located on concentric with a center circumference.
Further, the corner of described double wedge is provided with fillet.
Further, the width of described double wedge is less than or equal to the spacing between adjacent double wedge.
Further, described locking device by metal material bulk heat treatmet aftershaping again after Punching Technology.
Further, the hardness after described locking device heat treatment is hrc45-55.
Compared with prior art, advantages of the present invention and beneficial effect:
1st, product design of the present invention is ingenious, loads light, but pull-out strength is larger, good limit effect.
2nd, product quality of the present invention is light, and low cost is easy to make.
