Embodiment
The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, and can not be construed to
Limitation of the present invention.
As shown in Figures 2 and 3, embodiments of the invention provide a kind of back axle flange return survey tool, including dial 1
With pointer 2；For the dial 1 on reducer shell 3, the dial 1 is parallel with the end face of flange 4；The pointer 2 with
The flange 4 is connected, and the center line of the pointer 2 is parallel with the end face of the flange 4, and the pointer 2 can surround the flange 4
Axis rotate.Wherein, dial 1 is preferably affixed with the reducer shell 3.Pointer 2 is arranged to the knot that can be driven by flange 4
Structure, pointer 2 can be selected to be affixed with flange 4, it can also be provided that other structures that can be driven by flange 4.Pointer 2 is preferably set
It is set to the cone structure become narrow gradually from one end to the other end.
The application method of the back axle flange return survey tool of the embodiment of the present invention is：Dial 1 is connected to first and subtracted
On fast device housing 3, the direction of dial 1 is adjusted, makes it parallel with the end face of flange 4, then pointer 2 is connected on flange 4,
Ensure that the center line of pointer 2 is parallel with the end face of flange 4, and pointer 2 can surround the axis rotation of flange 4, then by back axle half
Axle is locked, and turn left flange 4, and pointer 2 is rotated with flange 4 in the process, and flange 4 turns to the extreme position in left side
When, the reading of now pointer 2 is write down, then turn right flange 4, and pointer 2 may proceed to as flange 4 rotates, and flange 4 turns to
During the extreme position on right side, the reading of now pointer 2 is write down, reading subtracts each other twice for this, just obtains the rotating freely for angles of flange 4；Root
Understood according to aforesaid operations step, compared to method of scoring measurement flange return is used in the prior art, using the embodiment of the present invention
Back axle flange return survey tool measures flange return, can save cumbersome line and measurement work, not only simplify measurement
