Abstract
The utility model provides a transmission shaft connecting structure of a washing machine dewatering barrel. Higher connecting strength exists among a barrel body, a flange and a transmission shaft, and the safety performance of the dewatering barrel is improved. The transmission shaft connecting structure of the washing machine dewatering barrel comprises the barrel body, and a shaft assembly is arranged at the bottom of the barrel body. The transmission shaft connecting structure of the washing machine dewatering barrel is characterized in that the shaft assembly comprises a flange part and a transmission part which are coaxial and are connected in a rigid mode, and the flange part is coaxially sealed into the bottom face of the barrel body and is connected with the barrel body to form a whole.
Description
Technical field
The utility model relates to the device for washing machine technical field, relates in particular to laundry machine dehydration device technique field, is specially a kind of transmission shaft connecting 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, between the output shaft of transmission shaft and drive unit, by coupling or speed reducer, are connected.Its staving of traditional dehydration barrel, flange and transmission shaft are package assembly, and between staving and flange, by bolton, between flange and transmission shaft, key is connected, 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 are used bolton, and efficiency of assembling is low.
Summary of the invention
For the problems referred to above, the utility model provides a kind of transmission shaft connecting structure of dehydrating vessel in washing machine, has higher join strength between its staving, flange and transmission shaft, has improved the Safety performance of dehydration barrel.
Its technological scheme is such, a kind of transmission shaft connecting 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 described flange part, the lead to the hole site that be positioned at described staving bottom, encapsulates the corresponding described flange of chamber of described flange part protrudes out the positioning convex matched 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 the utility model structure, its beneficial effect is: staving, flange part and transmission shaft are partly a rigidly connected overall structure, join strength is high, 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 larger, 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 and the through hole of flange part match, and the selection of square flange part can improve the join strength of flange part and staving, further guarantee the Safety performance of dehydration barrel, on the other hand, transmission shaft partly with between flange part is connected by the friction welding mode, and join strength is high, the endurance performance is good, further guarantees the Safety performance of dehydration barrel, simultaneously, staving, flange part and transmission shaft are partly an overall structure, have avoided follow-up assembling procedure, have improved manufacturing efficiency, .
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The structural representation that amplify the part that Fig. 2 is A place in Fig. 1.
Embodiment
As shown in Figure 1, a kind of transmission shaft connecting structure of dehydrating vessel in washing machine, it comprises staving 1, staving 1 bottom is provided with shaft assembly, shaft assembly comprises coaxial and rigidly connected flange part 2 and transmission shaft part 3, and flange part 2 coaxial packaging connect into integral body in staving 1 bottom surface and with staving 1; Be evenly distributed with several through holes 5 on flange part 2, through hole 5 position male that are positioned at chamber 6 companion flanges of staving 1 bottom, encapsulation flange part 2 are stretched out the positioning convex 4 matched with through hole 5; The circumferential profile of flange part 2 is square; Flange part 2 is packaged in the chamber 6 of staving 1 bottom by the injection moulding mode; Flange part 2 is connected by the friction welding mode with transmission shaft part 3.
