Description
Technical field
The utility model relates to medium-and-large-sized direct current machine width muscle axle key interconnection technique, is related specifically to a kind of medium-and-large-sized direct current machine width muscle axle key syndeton.
Background technology
Medium-and-large-sized DC motor rotor adopts width muscle axle as rotation axis usually, and so-called width muscle axle refers to and is circumferentially provided with cross former at axle, and rotor laminated iron core is fixed on the outside of cross former, thus forms rotor core.Prior art medium-and-large-sized direct current machine width muscle axle key syndeton adopts two relative formers in width muscle axial cross shape former circumferentially to arrange keyway, the former position being provided with keyway in the correspondence of laminated iron core inner circle arranges keyway, square key slotted eye is formed by relative with the keyway of laminated iron core inner circle for the keyway on former during installation, a flat key is thrown into wherein in a dowel hole, in another dowel hole, throw a taper key into, thus width muscle axle and laminated iron core are fixed together.Described flat key refers to that cross section is rectangle and the constant connecting key of size, and described taper key refers to two pieces of overlapped keys, and its faying surface is relative inclined-plane, and when relative movement, the height of the square-section that two pieces of keys are formed will change.This key syndeton all needs to process keyway at width muscle axle and laminated iron core, and is only circumferentially provided with key connection at relative two formers, and not only processing difficulties, but also the discontinuity making width muscle axle, can not better adapt to impact load.Obviously, prior art medium-and-large-sized direct current machine width muscle axle key syndeton also exists processing difficulties, width muscle axle unbalance stress is even can not better adapt to the problems such as impact load.
Summary of the invention
For solving processing difficulties that prior art medium-and-large-sized direct current machine width muscle axle key syndeton exists, width muscle axle unbalance stress is even can not better adapt to the problems such as impact load, the utility model proposes a kind of medium-and-large-sized direct current machine width muscle axle key syndeton.The utility model medium-and-large-sized direct current machine width muscle axle key syndeton, is circumferentially provided with connection boss at width muscle axle four formers, the height of described connection boss and the degree of depth of laminated iron core keyway matches, width is narrow compared with the width of laminated iron core keyway; Keyway is provided with in the position of laminated iron core inner circle corresponding width muscle axle former, and, horizontal taper key is provided with between two sides connecting boss and laminated iron core key slot side, described horizontal taper key refers to the key of two pieces of mutual lateral overlaps, its faying surface is relative inclined-plane, when its relative movement, the width of the square-section that two pieces of keys are formed will change.
The Advantageous Effects of the utility model large-scale dc motor width muscle axle key syndeton is the reduction of the processing of width muscle axle former circumferentially keyway, four formers are all fixedly connected with laminated iron core, improve the force-bearing situation of width muscle axle, impact load can be adapted to preferably.Further, structure is simple, handling ease.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of medium-and-large-sized direct current machine width muscle axle key syndeton;
Accompanying drawing 2 is the schematic diagram of the utility model medium-and-large-sized direct current machine width muscle axle key syndeton;
Accompanying drawing 3 is the close-up schematic view of accompanying drawing 2.
Below in conjunction with the drawings and specific embodiments, the utility model medium-and-large-sized direct current machine width muscle axle key syndeton is further described.
Embodiment
Accompanying drawing 1 is the schematic diagram of medium-and-large-sized direct current machine width muscle axle key syndeton, and in figure, 1 is width muscle axle, and 2 is laminated iron core, and 3 is flat key, and 4 is taper key.As seen from the figure, prior art medium-and-large-sized direct current machine width muscle axle key syndeton adopts two relative formers in width muscle axial cross shape former circumferentially to arrange keyway, the former position being provided with keyway in the correspondence of laminated iron core inner circle arranges keyway, square key slotted eye is formed by relative with the keyway of laminated iron core inner circle for the keyway on former during installation, a flat key is thrown into wherein in a dowel hole, in another dowel hole, throw a taper key into, thus width muscle axle and laminated iron core are fixed together.Described flat key refers to that cross section is rectangle and the constant connecting key of size, and described taper key refers to two pieces of overlapped keys, and its faying surface is relative inclined-plane, and when relative movement, the height of the square-section that two pieces of keys are formed will change.This key syndeton all needs to process keyway at width muscle axle and laminated iron core, and is only circumferentially provided with key connection at relative two formers, and not only processing difficulties, but also the discontinuity making width muscle axle, can not better adapt to impact load.Obviously, prior art medium-and-large-sized direct current machine width muscle axle key syndeton also exists processing difficulties, width muscle axle unbalance stress is even can not better adapt to the problems such as impact load.
Accompanying drawing 2 is the schematic diagram of the utility model medium-and-large-sized direct current machine width muscle axle key syndeton, and accompanying drawing 3 is the close-up schematic view of accompanying drawing 2, and 1 is width muscle axle, and 2 is laminated iron core, and 11 for connecting boss, and 5 is horizontal taper key.As seen from the figure, the utility model medium-and-large-sized direct current machine width muscle axle key syndeton, boss 11 is connected, the height of described connection the boss 11 and degree of depth of laminated iron core 2 keyway matches, width is narrow compared with the width of laminated iron core 2 keyway being circumferentially provided with of width muscle axle 1 four formers; Keyway is provided with in the position of laminated iron core 2 inner circle corresponding width muscle axle former, and, horizontal taper key 5 is provided with between two sides connecting boss 11 and laminated iron core key slot side, described horizontal taper key 5 refers to the key of two pieces of mutual lateral overlaps, its faying surface is relative inclined-plane, when its relative movement, the width of the square-section that two pieces of keys are formed will change.The utility model medium-and-large-sized direct current machine width muscle axle key syndeton circumferentially arranges connection boss at width muscle axle four formers, decreases the processing of width muscle axle former circumferentially keyway, reduces difficulty of processing.Further, be provided with at width muscle axle four formers and be connected with the key of laminated iron core, improve the force-bearing situation of width muscle axle, impact load can be adapted to preferably.
Obviously, the Advantageous Effects of the utility model medium-and-large-sized direct current machine width muscle axle key syndeton is the reduction of the processing of width muscle axle former circumferentially keyway, four formers are all fixedly connected with laminated iron core, improve the force-bearing situation of width muscle axle, can adapt to impact load preferably.Further, structure is simple, handling ease.
