A stator positioning part is arranged protrudingly on the periphery of the bearing fixing part and is used for mounting and positioning a stator. In the technical scheme, the stator positioning part is used for replacing a low-rotation-rate bearing support base annular flange outer edge as a stator installation base level, thereby reducing the thickness of the annular flange, saving materials and reducing cost.
Description
Technical field
The present invention relates to bearings field, particularly relate to a kind of bearing support block and there is its washing machine.
Background technique
Roller washing machine includes urceolus and inner core, for the roller washing machine of existing motor direct-drive type, stator is fixed on urceolus rear portion, rotor is fixed in the rotating shaft of inner core, and bearing is installed in inner core rotating shaft, and bearing inner race is rotatable, outer ring is fixedly mounted on bearing support block, bearing support block and urceolus are connected as a single entity, and namely stator and urceolus maintain static, and rotor drives inner core to sway.
Bearing support block has axle sleeve oblique crank Z and holds fixing part and stator engagement portion, and bearing fixing part is used for spring bearing; Stator engagement portion is used for fastening stator.The production process that bearing support block embeds after urceolus is that the bearing support block processed is put into mould, then carries out injection moulding, is embedded in urceolus by bearing support block and produces.
Patent publication No. is the Chinese patent literature of CN202023847U, disclose a kind of bearing support block and there is the roller washing machine of this bearing support block, as shown in Figure 1, this bearing support block has the fixing column of bearing fixing part 02, the annular flange flange 03 of bearing fixing part 02 upper end and the outer circumferential face projection from bearing fixing part 02 in sleeve-like, described fixing column composition stator engagement portion 01.When stator is installed, with the outer of annular flange flange 03 for datum clamp face, stator is positioned, to make stator coaxial with datum clamp face, thus make to keep good coaxality between inner core and urceolus, between stator and rotor.
The bearing used due to roller washing machine different rotating speeds is different, the bearing of the slow-speed of revolution (800-1200rpm) is less than the diameter of high rotating speed (1400rpm, 1600rpm), thus causes bearing fixing part 02 inner ring diameter of the bearing support block of 800-1200rpm little.Size due to used stator is identical, and namely the diameter of bearing fixing part 02 outer ring is identical, and the annular flange flange 03 so just causing the bearing support block of 800-1200rpm is thicker, causes the waste of material, the increase of cost.
For above problem, need badly and want a kind of new bearing support block, to solve the waste of prior art middle and slow speed of revolution roller washing machine bearing supporting base materials, cost is high, the irreducible problem of washing machine cost.
