Abstract
The utility model provides an aluminum alloy motor cover, it can be solved, and motor cover is easy among the prior art because of the rotor rotates the high fever that produces the inflation takes place, causes the fit -up gap grow between bearing and the bearing frame, and then produces the noise or damage the technical problem of bearing, rotor. It includes lid and bearing frame, its characterized in that: the draw -in groove that distributes on the bearing frame and have a plurality of edges radially to run through, draw -in groove intussuseption be equipped with with draw -in groove appearance complex rubber pad.
Description
Technical field
This utility model is related to motor, and in particular to a kind of aluminium alloy electric cover.
Background technology
Motor generally comprises housing, rotor and motor cover, and the bearing coordinated with the shaft end of rotor, bearing are provided with motor cover
It is installed in bearing block.Existing motor cover and bearing block are generally integrally formed by casting, and the motor cover of aluminum alloy material
Easily expand because rotor rotates the hyperpyrexia for producing, cause the fit-up gap between bearing and bearing block to become big, produce noise or
Person damages bearing, rotor.
Utility model content
For the problems referred to above, this utility model provides a kind of aluminium alloy electric cover, and it can solve motor in prior art
Lid is easily expanded because rotor rotates the hyperpyrexia for producing, and causes the fit-up gap between bearing and bearing block to become big, and then is produced
Noise damages bearing, the technical problem of rotor.
Its technical scheme is such, and it includes lid and bearing block, it is characterised in that：If being distributed with the bearing block
The dry draw-in groove for extending radially through, is filled with the rubber cushion blocks with the draw-in groove form fit in the draw-in groove.
Further, the draw-in groove includes draw-in groove leading section and the draw-in groove rearward end being interconnected, the draw-in groove leading section
The periphery of the bearing block is connected, the draw-in groove rearward end connects the endoporus of the bearing block, the width of the draw-in groove leading section
Less than the draw-in groove rearward end width and by smooth curve connection.
Further, the bearing block is circumferentially evenly arranged with the reinforcement arm being connected with the side wall of the lid.
Aluminium alloy electric cover of the present utility model, is distributed with some draw-in grooves for transversely running through, the draw-in groove on bearing block
The rubber cushion blocks with the draw-in groove form fit are inside filled with, the coefficient of expansion of rubber cushion blocks is more than the coefficient of expansion of aluminium alloy,
In the case of being heated, rubber is heated and expanded to draw-in groove both sides, all the time clamping bearing, and then avoids bearing from beating, it is to avoid generation is made an uproar
Sound damages bearing, rotor.
Description of the drawings
Fig. 1 be structural representation of the present utility model, not shown rubber cushion blocks.
Fig. 2 is the overlooking the structure diagram of draw-in groove of the present utility model.
Fig. 3 is the overlooking the structure diagram of rubber cushion blocks of the present utility model.
Specific embodiment
As shown in Fig. 1 ~ Fig. 3, it includes the body of lid 1 and bearing block 2, the circumferential side wall being evenly arranged with lid 1 of bearing block 2
The reinforcement arm 4 of connection, is distributed with some draw-in grooves 21 for extending radially through, draw-in groove 21 on bearing block 2 and is filled with and draw-in groove profile
The rubber cushion blocks 3 of cooperation；Draw-in groove 21 includes draw-in groove leading section 211 and the draw-in groove rearward end 212 being interconnected, draw-in groove leading section
The periphery of 211 connection bearing blocks 2, draw-in groove rearward end 212 connects the endoporus of bearing block 2, and the width of draw-in groove leading section 211 is less than card
The width of groove rearward end 212 is simultaneously connected by the curve 213,214 for smoothing；Draw-in groove rearward end both sides are formed with respectively to recessed
Along the fluting that inner hole of bearing seat is arranged, the opening of fluting connects the endoporus of bearing block so that rubber cushion blocks are swollen along fluting direction
It is swollen, increase the area that rubber cushion blocks are fitted with bearing outer ring.
