17.2 Partial Assembly of indexing
cam drive.
17.21 Assembly of Follower Shaft
(Axis II): fig. 17.6.
Assemble all the components (70, 71,
76 to 84) as shown in fig. 6, which
shows details of BTP-63 and BTP-80
cam drive.
Refer main assembly drawing (fig.,
page) for BTP-100 and BTP-125 de-
tails.
17.22 Partial Assembly of Cam Shaft
(Axis III):fig. 17.6.
Assemble the components (70, 71, 73,
74, 75) as shown in fig 6. Remaining
components of the cam shaft are to be
assembled at a later stage.
Indexing cam (75) may be in a single
piece, or in two pieces depending on
method of manufacture. If in two piec-
es, ensure that the assembly confirms
to the side view shown in the figure.
17.3 Intermediate Assembly of Spin-
dle and indexing drive (Axis I, II and
III) in main Body : fig 17.7.
Fit the partial spindle assembly into the
main body (45) with the help of bolts (2)
and cyl. pins (40). Also ensure that ‘O’
Ring (41) is in place.
Fit anti rotation key (6) in place.
Hold indexing drive subassemblies side
by side in proper orientation as shown
in Fig. 17.6. Circular parts of cam (75)
should contact the rollers (78). Orien-
tation marks on gears (73) and (83)
should be positioned as shown in fig-
ure 17.6.
Fit these subassemblies in the main
body (45), without loosing their general
orientation. Simultaneously it is neces-
sary to ensure that the teeth of drive
gear (73) and drum cam gear (8) mesh
with orientation marks properly aligned.
It might be necessary to use a torch
light to check the alignment.
