Abstract
The invention provides a connecting structure of a transmission shaft of a dehydrating barrel of a washing machine, wherein higher connection intensity is provided among a barrel body, a flange and the transmission shaft, so that safety performance of the dehydrating barrel is improved. The connecting structure comprises the barrel body, wherein a shaft assembly is arranged at the bottom of the barrel body, the connecting structure is characterized in that the shaft assembly comprises a flange part and a transmission shaft part, which are coaxially and rigidly connected, and the flange part is coaxially packaged in the bottom surface of the barrel body and is connected to the barrel body to form a whole body.
Description
Technical field
The present invention relates to the device for washing machine technical field, relate in particular to laundry machine dehydration device technique field, be specially the transmission shaft linkage structure of dehydrating vessel in washing machine.
Background technique
The laundry machine dehydration device comprises dehydration barrel and drive unit, dehydration bucket bottom is equipped with the shaft assembly that is driven and driven the dehydration barrel rotation by drive unit, shaft assembly comprises flange and transmission shaft, along the staving axis, staving, flange and transmission shaft are connected successively, link to each other by coupling or speed reducer between the output shaft of transmission shaft and drive unit.Its staving of traditional dehydration barrel, flange and transmission shaft are package assembly, and by bolton, key is connected between flange and the transmission shaft between staving and the flange, because dehydration barrel rotates under the effect of drive unit, the torsion that rotation produces directly acts on flat key and bolt, and under long twisting force, flat key is easy to wear, bolt easily produces twisting and breaking, join strength is low, causes the dehydration barrel poor safety performance, simultaneously, staving and flange use bolton, and efficiency of assembling is low.
Summary of the invention
At the problems referred to above, the invention provides the transmission shaft linkage structure of dehydrating vessel in washing machine, have higher join strength between its staving, flange and the transmission shaft, improved the Safety performance of dehydration barrel.
Its technological scheme is such, the transmission shaft linkage structure of dehydrating vessel in washing machine, it comprises staving, described staving bottom is provided with shaft assembly, it is characterized in that: described shaft assembly comprises coaxial and rigidly connected flange part and transmission shaft part, and the flange part coaxial packaging connects into integral body in the staving bottom surface and with staving.
It is further characterized in that:
Be evenly distributed with several through holes on the described flange part, the lead to the hole site that is positioned at the corresponding described flange of chamber of described staving bottom, the described flange part of encapsulation protrudes out the positioning convex that matches with described through hole;
The circumferential profile of described flange part is square;
Described flange part is packaged in the chamber of described staving bottom by the injection moulding mode;
Described flange part partly is connected by the friction welding mode with described transmission shaft.
After adopting structure of the present invention, its beneficial effect is: staving, flange part and transmission shaft partly are a rigidly connected overall structure, the join strength height, mechanical property is good, on the one hand, flange part is packaged in the staving bottom surface by the injection moulding mode, the flange part of shaft assembly is embedded in the injection forming mold of staving, the staving of moulding is packaged in the flange part of shaft assembly in the chamber of bottom, the torsion that the staving rotation produces directly acts on flange part, because the cross section of flange part is bigger, the degree of its torsibility is much larger than traditional bolt, guarantee the Safety performance of dehydration barrel, and the positioning convex that staving forms in injection moulding process matches mutually with the through hole of flange part, and the selection of square flange part can improve the join strength of flange part and staving, further guarantees the Safety performance of dehydration barrel; On the other hand, be connected by the friction welding mode between transmission shaft part and the flange part, join strength height, endurance performance are good, further guarantee the Safety performance of dehydration barrel; Simultaneously, staving, flange part and transmission shaft are an overall structure partly, have avoided follow-up assembling procedure, have improved manufacturing efficiency;
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that amplify the part at A place among Fig. 1.
