Abstract
Heat radiator for be used for inverter motor, including a heat dissipation impeller, the center department of the impeller that should dispel the heat is fixed with the disc base, a fixed intermediate gear on this disc base, a through -hole has been seted up at intermediate gear's center, and this through -hole divide into two sections, and one section is the motor shaft section of holding, and another section is the internal spline section, the diameter of the motor shaft section of holding is greater than internal spline section, combination department between them constitute step portion, just the junction that the motor shaft holds duan zaiyu internal spline section is equipped with the recess. The utility model discloses be equipped with the recess owing to hold the junction of duan zaiyu internal spline section at the motor shaft, the root and the intermediate gear of motor shaft can not lead to the fact wearing and tearing because of the friction.
Description
Technical field
The utility model relates to a kind of heat abstractor for variable-frequency motor, belongs to washing machine appurtenances technical field.
Background technology
Roller washing machine variable-frequency motor can generate heat in a large number in running, and too much heat is unfavorable for variable-frequency motor running.Internal machine volume is limited simultaneously, has strict demand for heat abstractor volume.For coordinating the installation of roller washing machine variable-frequency motor heat abstractor, need to design a kind of jockey.Publication number is CN202867594U, name is called that the utility model patent of " a kind of idler gear for connecting variable-frequency motor heat abstractor " discloses a kind of technical scheme: idler gear is connected to heat-dissipating impeller center by intermediate connector, described idler gear is cylinder, it is internal spline inside described idler gear, one end is provided with discoidal base, and described chassis outer side is external splines.The defect that idler gear exists is: when motor shaft is fitted within idler gear, the root of motor shaft and idler gear can cause wearing and tearing because of friction.
Summary of the invention
The utility model provides a kind of heat abstractor for variable-frequency motor.
For achieving the above object, the technical solution adopted in the utility model is: a kind of heat abstractor for variable-frequency motor, comprises a heat-dissipating impeller, and the center of this heat-dissipating impeller is fixed with disc-shaped base, this disc-shaped base is fixed an idler gear; The center of described idler gear offers a through hole, and this through hole is divided into two sections, and one section is motor shaft accommodating section, and another section is internal spline section; The diameter of described motor shaft accommodating section is greater than described internal spline section, and both junctions form stage portion, and described motor shaft accommodating section is provided with groove in the junction with internal spline section.
Preferred technical scheme is: the material of described disc-shaped base is high molecule plastic.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is owing to being provided with groove in motor shaft accommodating section in the junction with internal spline section, and the root of motor shaft and idler gear can not cause wearing and tearing because of friction.
Accompanying drawing explanation
Accompanying drawing 1 is idler gear cross-sectional schematic.
Accompanying drawing 2 is heat abstractor schematic diagram.
In above accompanying drawing, 1, idler gear; 2, motor shaft accommodating section; 3, internal spline section; 4, groove; 5, heat-dissipating impeller; 6, disc-shaped base.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
