Chapter Five Debugging Method of Power tiller
Ⅰ
. Debugging Method of Mesh of Bevel Gear
When the abnormal transmission of mesh of bevel
gear of sound is confirmed, stop the machine and
check as stipulated below:
1. Clearance adjustment of mesh of angel gear in
gear-box ( See Figure 10)
①
When lateral clearance of mesh of the gear
△＜
0.05mm,we should put some vulcanized paper
to enlarge the clearance between the gear-box and the
traveling box.
②
When lateral clearance of mesh of the gear
△＞
0.3mm,we should reduce the clearance to 0.05-0.10
mm between the bearings and gear
Ⅱ
shaft
2. Clearance adjustment of mesh of the gear in the
running case.(See Figure 11)
①
When lateral clearance of mesh of the gear
△ ＜
0.05mm,we should increase adjustment
pad
Ⅰ
by 0.2-0.3mm to enlarge the clearance, and
change vulcanized paper board
Ⅱ
and adjustment
pad.
Ⅲ
. To ensure the axial clearance of the gear
Ⅱ
is 0.05-
0.15mm.
②
When lateral clearance of mesh of the
gear
△ ＞
0.3mm, we should reduce adjustment
pad
Ⅰ
, meanwhile the axial clearance of gear
Ⅱ
is
0.05-0.15mm,or increase the adjustment pad
Ⅱ
,
meanwhile ensure the axial clearance of gear
Ⅰ
is
0.05-0.15mm.
Ⅱ
. Debugging Method of Reversing Gears and
Cables
When the power tiller
’
s running backwards is not
normal, it is necessary to adjust the reversing gears
and Cables, see Chapter Three for the methods.
Note: 1. Grasp and loosen the reversing handle for 2-3 minutes to confirm the putting
into gear. If it is abnormal, adjust it until it is qualified.
2. When the power tiller is running, loosen the reversing handle, the reversing gears
should return to its original position and no abnormal sound by gears colliding in the
gear-box, otherwise, it may cause damage to the gear.
Ⅲ
Debuggin g Method of Clutch Cables
After some time use, the clutch does not perform well any more due to the weariness
of friction piece and fork of clutch. As for how to adjust cable of the clutch, refer to
Chapter Three for know-how.
Note: 1. Grasp and loosen the clutch handle for 2-3 times to confirm the clutch status.
If abnormal, readjust it.
2. If repeated adjustment can not solve the problem, excess abrasion of fork or friction
