Deviate on line and rotated in an oscillatory manner.Therefore, operator, can be easy when carrying out the Inspection of encoder 21
Ground is with the former state of visual identification and the state of the latter, in the latter case, the installation to rotational circle tabular seal 19
Position is adjusted again.
So, in the case where rotational circle tabular seal 19 does not form shaft-like test section 20a, it is impossible to visual identification
Whether the rotary shaft 20b linked between encoder 21 and rotational circle tabular seal 19 is correctly positioned at rotational circle tabular seal
On 19 rotation centerline.In this case, in order to visually to confirm to it, it is necessary to looked into from the rear side of traction machine 4
In the hollow bulb 7a for seeing rotational circle tabular seal 19.On the other hand, in the present embodiment, because in the sealing of rotational circle tabular
The side of car 2 of body 19 is coaxially formed with shaft-like test section 20a with rotary shaft 20b, so can be according to shaft-like test section 20a's
The difference of the mode of rotation, visually simply to differentiate whether rotational circle tabular seal 19 is fixed on correct position.
In addition, in the case where needs alternate coding device 21 because of adjustment, maintenance inspection, by rotational circle tabular seal 19
Remove, the signal wire 23 in hollow bulb 7a is drawn a little and connector 21 and signal wire 23 is separated in connecting portion 22, will be compiled
Code device 21 takes out out of hollow form main shaft 7 hollow bulb 7a.Afterwards, new encoder 21 is arranged on connecting portion 22, afterwards, peace
Fill rotational circle tabular seal 19.
And then, the oil leak of the deterioration leakage with oil sealing part 25 is dripped to after oily spatial portion 16 as described above,
Guiding is leaked to the oil storage portion 34 being arranged as opposed to the side of car 2, therefore with the presence or absence of the deterioration with oil sealing part 25
The confirmation of oil leak also can easily be carried out from the side of car 2.
In addition, instead of operator from the sidelong glance optical axis shape test section 20a of car 2, and replace operator to differentiate shaft-like detection
Whether portion 20a correctly rotates on the rotation centerline of rotational circle tabular seal 19, can use detection shaft-like test section
The detection means of the mode of 20a rotation, to differentiate to whether rotational circle tabular seal 19 configures in correct position.
In the present embodiment, when observing shaft-like test section 20a, the differentiation that can be discussed below：If
Rotational circle tabular seal 19 is configured in correct position, then shaft-like test section 20a is located on rotation centerline without swinging
Ground rotates on rotation centerline, on the other hand, if rotational circle tabular seal 19 is somewhat inclined from its pivot to radial direction
Liftoff configuration, then shaft-like test section 20a deviate from original rotation centerline and swingingly rotated, so as to simple
Ground knows whether rotational circle tabular seal 19 is fixed on correct position.
