The mount serves to fasten the motor to the Linear Module and acts as a closed housing for the coupling. The coupling transmits the motor drive torque free of distortive stresses to the Linear Module’s drive shaft. Our standard couplings compensate for the system’s thermal expansion. 1 Motor 2 Mount 3 Coupling 4 Linear module Motor attachment via timing belt side drive On all linear modules with a ball screw drive the motor can be attached via 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 provides protection for the belt and acts as a motor bracket. In addition, various gear ratios are available. The timing belt side drive can be mounted in four different directions. 1 Pulley housing made of anodized aluminum 2 In some cases with support bearing for Rexroth Ball Screw Assembly screw journal. 3 Linear module 4 Belt drive with gear ratio: i = 1; i = 1,5; i = 2 5 Servo motor 6 Pre-tensioning of the belt drive: Apply preload force Fpr to the motor (Fpr is stated upon delivery). 7 Cover 8 Belt pulleys attached using tensioning units 9 Cover plate Technical data General technical instructions Note on dynamic load capacities and load moments Determination of the dynamic load capacities and load moments is based on a travel life of 100 000 m. Often only 50 000 m is actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26. Suitable loads Regarding the desired nominal life, in general loads for Fcomb, Fm up to around 20 % of the dynamic characteristic values ( C , M t , M L ) have generally proven suitable. See the "Calculation" document in the "Project planning instructions" chapter for the respective Linear Module. Do not exceed the technical data for the Linear Motion System. Application point of the effective force (Z1) Modulus of elasticity E of the Linear Motion System General technical instructions Length calculation of the Linear Motion System 1) with protective bellows For length calculation values, see the "General Technical Data" table. Note: Adhere to the section "General technical instructions" and the document "Calculation" in the chapter "Project planning instructions".
