Motor attachment 1) Mount and coupling 2) Timing belt side drive Attachments: 1 Mount and coupling 2 Timing belt side drive 3 Motor Construction of mount and coupling For all Drive Units, a motor can be mounted via the mount and coupling. The mount secures the motor to the Drive Unit and serves as a closed housing for the coupling. The coupling transmits the motor drive torque to the Drive Unit's drive shaft without distortive stresses. Our standard couplings compensate for the system's thermal expansion. 1 Motor 2 Mount 3 Coupling Construction of timing belt side drive The motors of all Drive Units can be attached using a timing belt side drive. This makes the overall length shorter than when attaching the motor with a mount and coupling. The space-saving, closed pulley housing serves as protection for the belt and as a motor bracket. In addition, various gear ratios are also available (depending on size): i = 1 i = 2 The timing belt side drive can be mounted in four different directions: bottom, top (RV01 and RV02) left, right (RV03 and RV04) 1 Pulley housing made of anodized aluminum frame 2 Timing belt 3 Motor 4 Timing belt pretensioned: Apply preload force Fpr to the motor (Fpr will be indicated on delivery) 5 Cover 6 Attaching the belt pulleys with tensioning units 7 Cover plate for timing belt side drive Technical data Note: Observe the document "Calculation" in the section "Project planning notes".
