5. a kind of detection method for alternating current generator gear diameter according to claim 1, it is characterised in that: operation side
Method, comprising the following steps:
Step 1: operator starts power motor (20), power motor (20) operation will make long axis (23) by second
Driving gear (26) drives the second driven gear (24) rotation, and two volume blocks (25) will can rotate and roll connection respectively at this time
It restricts (27), so that separating between two locating pieces (15), then operator will need the gear detected to be placed on long slab (3)
Top, and two movable blocks (11) are located in the inner ring of gear.
Step 2: operator makes power motor (20) control long axis (23) reversion, so that two volume blocks (25) are respectively
Connecting rope (27) are unclasped, at this time since the spring return effect of flexure spring (16) will make two locating pieces (15) transport in opposite directions
It is dynamic, so that the outer surface to gear positions.
Step 3: operator starts driving motor (6), the operation of driving motor (6) will make shaft (7) main by first
Moving gear (8) drives the first driven gear (10) rotation, and it is opposite that rotating bar (9) rotation at this time will will drive two movable blocks (11)
Movement, and movable block (11) movement will will drive the second digital scale ruler (30) and moving mass (12) movement, when two movable blocks
(11) when outside is contradicted respectively to gear inner wall, make driving motor (6) out of service at this time, then observe first and refer to
Show the indicated number on the first digital scale tooth (28) at the top of needle (29), obtained number will be observed and multiplied in two, as
The diameter of the gear, and it is it is known that observing the second indicator at this time that two movable blocks (11), which are located at the length in inner ring gear,
(31) the indicated number on the second digital scale ruler (30) in top, the number observed is multiplied in two along with two movements
The length of block (11) is the diameter of the inner ring gear.
6. a kind of detection method for alternating current generator gear diameter according to claim 5, it is characterised in that: the shifting
The quantity of motion block (11) is two, and the inside of two movable blocks (11) offers threaded hole, inside two threaded holes
Screw thread is opposite.
7. a kind of detection method for alternating current generator gear diameter according to claim 5, it is characterised in that: the fortune
The inside of motion block (12) offers round mouth, and the cross-sectional area of round mouth side is equal with the cross-sectional area of cross bar (2) side.
