Abstract
The utility model discloses a kind of switchgear shafts, including console panel, axle sleeve, shaft main body and nut, nut and axle sleeve are successively arranged in the shaft main body, one end of the shaft main body is equipped with spline, and the size of each key teeth is not exactly the same, and the other end of the shaft main body is set as chamfered edge axle construction, the console panel is equipped with chamfered edge corresponding with chamfered edge axis hole, and the shaft main body realizes the connection with console panel by chamfered edge hole and chamfered edge axle construction.The side of the console panel is equipped with pin hole, realizes that shaft main body is fixedly connected with the secondary of console panel by pin and pin hole.It is connected using spline, and the size of each key teeth is adjusted, be allowed to corresponding with the keyway on revolving part, guarantee that single angle insertion, spline connection increase torque, increase to neutrality, while easy to disassemble；Pin connection is added using chamfered edge axis between shaft and console panel, torque when pin being made to be not subjected to shaft work improves the service life of shaft.
Description
Technical field
The utility model relates to a kind of switchgear shafts.
Background technique
Switchgear shaft, common connection type is flat key connection, but flat key connection is bad to neutrality, while being not easy to tear open
It unloads.In addition, the connection type between shaft and connecting rod, common connection type is pin connection, when pin being made to bear shaft work
Torque, it is easy to damage, the service life of shaft also greatly shortens.
Utility model content
To solve the above problems, the utility model provides a kind of switchgear shaft, and it is good while easy to disassemble to neutrality, turn
The service life of axis increases.
The technical solution adopted in the utility model is: a kind of switchgear shaft, including console panel, axle sleeve, shaft main body and
Nut is successively arranged with nut and axle sleeve in the shaft main body, and one end of the shaft main body is equipped with spline, each key teeth
Size is not exactly the same, and the other end of the shaft main body is set as chamfered edge axle construction, and the console panel is equipped with and chamfered edge axis
Corresponding chamfered edge hole, the shaft main body realize the connection with console panel by chamfered edge hole and chamfered edge axle construction.
The side of the console panel is equipped with pin hole, realizes that the secondary fixation of shaft main body and console panel connects by pin and pin hole
It connects.
The beneficial effects of the utility model are: 1. replace the common flat key connection of switchgear shaft using spline connection, and
The size of each key teeth is adjusted, is allowed to corresponding with the keyway on revolving part, guarantees single angle insertion.2. compared to flat
Key connection, spline connection increase torque, increase to neutrality, while easy to disassemble.3. the connection between shaft and console panel
Mode is also changed to chamfered edge axis by common pin connection and adds pin connection, and torque when pin being made to be not subjected to shaft work improves
The service life of shaft.

Specific embodiment
In order to deepen the understanding to the utility model, below in conjunction with embodiment and attached drawing to the work of the utility model into one
Step is described in detail, which is only used for explaining the utility model, does not constitute the restriction to the protection scope of the utility model.
As shown in Figures 1 to 3, a kind of switchgear shaft, including console panel 1, axle sleeve 2, shaft main body 3 and nut 4, shaft master
Nut 4 and axle sleeve 2 are successively arranged on body 3, one end of shaft main body 3 is equipped with spline 31, the incomplete phase of the size of each key teeth
Together, it replaces the common flat key of switchgear shaft to connect using spline connection, and the size of each strong tooth is adjusted, be allowed to and revolve
The keyway turned on part is corresponding, guarantees single angle insertion, connects compared to flat key, and spline connection increases torque, increases
To neutrality, at the same it is easy to disassemble.The other end of shaft main body 3 is set as chamfered edge axis 32, and console panel 1 is equipped with right with chamfered edge axis 32
The chamfered edge hole 11 answered, shaft main body 3 realize the connection with console panel 1 by chamfered edge hole 11 and chamfered edge axis 32.The side of console panel 1
Equipped with pin hole, realize that shaft main body 3 is fixedly connected with the secondary of console panel 1 by pin 5 and pin hole.Pin is added to connect using chamfered edge axis
It connects, torque when pin being made to be not subjected to shaft work improves the service life of shaft.
Claims (2)
