2.6 Precaution of usage for B-SET
Please do not use torque that exceeds Allowable transfer capability.
Avoid overhang load action to input and output shafts. If there is overhang and thrust loads to gear shafts of theB-SET, it is necessary to design an extra preventable function. (Refer to Fig. 10)
Installation precaution (For efficient use of B-BOX)◇ To prevent damage to the gear shafts, gear
shaft of B-SET and mating shaft must bealigned at right angle before assembly.
◇ Before operation, it is necessary to confirm
smooth rotation of shafts by operating withhand.

◇ Beware of fingers or waste objects gettingcaught in a snap ring.

!

◇ T o prevent damage to the gear shafts,
provide accurate parallelism and shaft
centre between gear shaft of B-SET andmating shaft before assembly.

◇ Ensure that the body of B-SET is properly coveredby plastic cover before starting the machine.
◇ Follow steps ① and ② for instruction toproperly cover the plastic cover and handle
the cover with care.

◇ If there is a possibility that the plastic covermight come off during operation, use bolts
to secure the plastic cover.
Beware of damaging
the bearings andsurrounding area when
additional drilling iscarried out on the B-SET.

② Push the convex areaof plastic cover into
the concave grooveof body perfectly.

!

Attention◇ Apply grease to the Tooth and lubricant oil
to bearings regularly. Beware of running outof oil.

!

① S et the convex area of plastic cover tooverlap the concave groove properly.

Before operation, test run with no load is recommended to check for faults or noise.
Use flexible coupling to reduce misalignment between shaft of B-SET and mating shaft.
Beware of dust and particles clogging the bearing and Toothing.
When the gear is rotating at high speed at ratio 2:1, noise level and temperature will increase but power transfer will
decrease. The opposite is true at low speed.
During operation (For safety purposes, please pay attention to the followings below)◇ Do not touch the gearbox during operation.
◇ Beware of waste objects being caught inthe snap ring at the back of body.

!
Attention◇ Stop operation and check for faults if there
are any problems such as unusual soundand high temperature occurring fromgearbox. Do not start the machine until thefaults has been cleared.

◇ P lastic cover is available for purchase asspare parts for maintenance use when time
to be replaced due to aged deterioration.

Precaution of additional works(Take note to be careful to prevent loss of function when making additional machining works to B-SET)
To avoid damage to B-BOX, please do not hesitate to contact us if uncertain of details.
◇ Before additional machining, ensure that bearing
and gear portions are covered, so that wasteobjects will not contaminate it.
◇ For additional machining to Drill hole diameter,
do not exceed limitation of drill holes sizes. Referto reference Figure from page 74.

◇ Put a support plate under the plastic cover when
doing additional drilling works.
Put a support plate under the plastic cover.
Plastic cover may break.
