Abstract
The utility model discloses a sealing structure for the motor of a dish washing machine. The sealing structure comprises a stator component (1), a rotor component (2) and a housing (3), wherein a wind wheel (4) is mounted on a rotating shaft (21) extending out of the end part of the housing (3). The sealing structure is characterized in that a plurality of splines (211) protrude from the outer surface of the rotating shaft (21) in the circumferential direction; a plurality of lug bosses (411) protrude from the inner wall of a central hole (41) of the wind wheel (4); the splines (211) and the lug bosses (411) are meshed with one another; and gaps among the splines (211) and the lug bosses (411) which are meshed with one another are filled and sealed through first sealant (5). The utility model has the advantages of good leak tightness, large transmitting torque, reliable operation, and stable property.
Description
Technical field:
The utility model relates to a kind of hermetically-sealed construction of dish-washing machine motor.
Background technology:
Traditional dish-washing machine motor axle and the sealing between the wind wheel, be by the incompatible realization of close-fitting, sealing between motor shaft and wind wheel is provided with fluid sealant in a small amount, when on the rotating shaft band during loaded work piece, it is too high that the motor feels hot, the part that wind wheel cooperates with rotating shaft can form melten gel, thereby causes wind wheel not worked when serious; 2, pass through the incompatible transferring power of close-fitting between motor shaft and the wind wheel, the transmission of this power is smaller, in case overload, loosening and gap can appear between motor shaft and the wind wheel, sealing between motor shaft and the wind wheel is destroyed, water leaks into the stator coil assembly of motor along motor shaft,, motor easily burning machine causes dishwasher not worked.
Summary of the invention:
The purpose of this utility model provides a kind of hermetically-sealed construction of dish-washing machine motor, its good airproof performance, and the moment of transmission is big, reliable operation, stable performance.
The purpose of this utility model is to be achieved by following technical scheme.
A kind of hermetically-sealed construction of dish-washing machine motor, comprise stator module and rotor assembly and casing, the rotating shaft of stretching out from the casing end is equipped with wind wheel, on the rotating shaft outer surface, circumferentially protrude several splines, inwall at the centre bore of wind wheel protrudes some boss, be meshing with each other between spline and the boss, sealing is filled with first fluid sealant in the space that produces that is meshing with each other between spline and the boss.
Above-mentioned described inwall at boss rear, centre bore is provided with step, forms the cavity volume that increases between the inwall of step and the outer surface of rotating shaft, fills second fluid sealant at cavity volume.
Above-mentioned described fluid sealant is a silica gel.
Above-mentioned described wind wheel is provided with some fan blades near on the side end face of motor.
The utility model compared with prior art has following beneficial effect: 1) circumferentially protrude several splines on the rotating shaft outer surface, inwall at the centre bore of wind wheel protrudes some boss, be meshing with each other between spline and the boss, be meshing with each other between spline and the boss space that produces is filled with first fluid sealant and is sealed, form primary seal, and can transmit bigger torsion, good airproof performance.Reliable operation; 2) inwall at boss rear, centre bore is provided with step, forms the cavity volume that increases between the inwall of step and the outer surface of rotating shaft, fills second fluid sealant at cavity volume, forms the secondary seal body, further improves sealing property.
