SUMMARY OF Motor Base
Three functions of Motor Base-
① Tension ② Damping ③ Making belt change easy
Operation of belt -
In case of V-belt, proper tension should be given to belt to transfer required torque to machine and facility effectively. Belt is stretched out by overload placed on belt when facility operates and, if no tension is given to belt at this time, belt slips, jumps and shakes. Furthermore, noise by friction sounds and worn out of pulley becomes significant
EFFECT OF Motor Base
  • Keeps proper tension on belt when belt stretches out.
  • Absorbs belt shaking in a second by swiveling so that overload can be placed on belt at initial operation.
  • Prevents slip.
  • Extends life of belt remarkably.
  • Self-damping function absorbs vibration of motor and shaking of belt in relaxed side.
  • Changing belt is simple.

Model OF Anti-Vibration Mounting
  • LMB-27: Use for electric motor (0.75Kw – 4Kw)
  • LMB-50: Use for electric motor (5.5Kw – 45Kw)
  • LMB-70: Use for electric motor (37Kw – 120Kw)
  • 5 kinds of Rubber Suspension Units are available depending on motor capacity.
  • Complete product of motor base is available but user also can make motor base by purchasing necessary kits only ( Most customers purchase Rubber Suspension.
  • Unit and Pretensioning Devices only and make brackets by cutting and bending according to the drawing and dimensions in product catalogue).
  • There are three grooves in Pretensioning Device and the grooves are for quick adjustment of plate angle.
  • Set proper tension of belt based on belt type and number of strands of belt.
  • LMB-27 is so compact that it can be installed in any place and also can be installed in the same place where old motor base was installed.
  • Pretensioning Device can be installed on either left side or right side depending on the position of counter pulley.

Motor plate (user-supplied) to allow for the best lever movement with off-center must be installed. Approximately 80mm in all types of LMB to move off-center to the point I recommend that you install.
