Abstract
The utility model provides a kind of motor gearbox iron covering riveting mechanism, adopt the following technical scheme that motor gearbox iron covering riveting mechanism, equally distributed riveting knife is vertically arranged including several, the riveting knife edge of a knife is set to the lower end side of riveting knife, edge of a knife shape is " ∫ " shape, is arc surface above the edge of a knife.The beneficial effects of the utility model are: limiting firmly by up and down direction, the direct active force to gear-box is avoided, for iron covering without obscission, performance is undamped, no friction abnormal sound.
Description
Technical field
The utility model relates to motor gearbox manufacturing fields, and in particular to a kind of riveting mechanism of gear-box iron covering.
Background technique
The iron covering riveting of motor gearbox, currently used is riveting knife transverse direction riveting, to the transverse pressure of motor gearbox
It is larger, keep its deformation larger, lead to armature spindle and bearing clearance side very little or abut, motor behavior in service is caused to decline,
And have friction abnormal sound.Because riveting knife-edge shape is stepped ramp type, also results in iron covering and fall off.
Utility model content
The utility model provides a kind of motor gearbox iron covering riveting mechanism, which can reduce gear-box change
Shape amount keeps armature spindle and bearing clearance uniform, and performance is unattenuated, no friction abnormal sound.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
Motor gearbox iron covering riveting mechanism, which is characterized in that equally distributed riveting knife is vertically arranged including several, it is described
The riveting knife edge of a knife is set to the lower end side of riveting knife, and it is arc surface above the edge of a knife that edge of a knife shape, which is " ∫ " shape,.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the side of the arc surface and the gear-box
It coincide.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the quantity of the riveting knife is 3, is uniformly distributed in
Gear-box side.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the edge of a knife is by iron covering riveting on gear-box.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the riveting knife setting up and down direction limits firmly.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the arc surface is mirror-finished, and Ra is little
In 0.2.
The beneficial effects of the utility model are: limiting firmly by up and down direction, the direct active force to gear-box, iron are avoided
Lid is without obscission, and performance is undamped, no friction abnormal sound.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the schematic diagram of riveting knife；
Fig. 2 is the main view of the utility model；
In figure: 1, riveting knife；2, the edge of a knife；3, arc surface；4, gear-box；5, iron covering.
Specific embodiment
The utility model is further described with reference to the accompanying drawing:
Motor gearbox iron covering riveting mechanism, which is characterized in that be vertically arranged equally distributed riveting knife 1, institute including several
The lower end side that the riveting knife edge of a knife 2 is set to riveting knife is stated, edge of a knife shape is " ∫ " shape, and 2 top of the edge of a knife is arc surface 3.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the side of the arc surface and the gear-box 4
It coincide.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the quantity of the riveting knife is 3, is uniformly distributed in
Gear-box side.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the edge of a knife is by 5 riveting of iron covering in gear-box
On.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the riveting knife setting up and down direction limits firmly.
Motor gearbox iron covering riveting mechanism above-mentioned, which is characterized in that the arc surface is mirror-finished, and Ra is little
In 0.2.
In use, being pressed vertically using riveting knife, the arc surface of riveting knife ensure that iron covering and gear-box fasten；Pass through upper and lower
To hard limit, avoid the direct active force to gear-box, reduce gear-box deflection
The beneficial effects of the utility model are: limiting firmly by up and down direction, the direct active force to gear-box, iron are avoided
Lid is without obscission, and performance is undamped, no friction abnormal sound.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
