Tsubaki BDTM201 - How to Input the Data; How to Input the Unit Mass; How to Input the Belt Width or the Number of Belts (Ribs); How to Input the Value of Span Length

6. How to input the data
6-1. How to input the unit
mass（Refer to the unit
mass tables on next page）
●
●
●
Timing belt & （Reference）Flat timing belt
To input the unit mass is width（mm） ×
length（m） in g/mm width × m Length.
1.Data capacity is 000.1〜999.9g/mm
width × m Length
2.Able to input with four significant digit
figures of three columns of integers and
decimal one column
Tooth belt from the pre-install data
Push "MASS" bottom more than one
second, belt type shows up on the screen.
With using "UP" or "DOWN" button to
select and push "MEASURE" to set.
（Reference） V belt, V-Ribbed belt, and Wire
Input the mass per meter of length in "g/m
length" for unit mass.
Able to input by four significant digits,
i.e. three digits of integer and one digit
below decimal point from 000.1 up to
999.9 g/m L. Unit mass corresponds to one
piece for V-belt and wire, and one rib for
V-ribbed belt.
6-2. How to input the belt
width or the number of
belts（ribs）
●
●
Timing belt & （Reference） Flat timing belt
To put the date is for belt width is
000.1mm〜999.9mm, three digits of
integer and one digit below decimal point
in mm.
（Reference） V belt, V-Ribbed belt, and Wire
For V belt and Wire, put one piece. For V
ribbed belt, put the number of ribs of
V-ribbed belt.
6-3. How to put the value of
span length
Span length is a distance between contacts
with pulley, and can be calculated by the f
following calculating formula.
Alternatively, measure the distance between
pulley contacts with a tape measure and put.
L ：Span length  （mm）
C ：Distance between axes （mm）
Dp ： Large pulley pitch outer diameter （mm）
dp：
Small pulley pitch outer diameter （mm）
L＝ C −

■Table2: For BDTM201 unit mass table
Data of unit mass can be input by four significant digits, i.e. three digits of integer and one digit
below decimal point in g/mm W x m L from 0.1 to 999.9 g/mm W x m L.
