1. Parallel kit EAMM-U-...-D...-...B/C/G/H-S1 The kit is intended for connecting an axis to a geared motor in a parallel configuration ( section 10) and it fulfils protection class IP65. Warning Risk of injury due to uncontrolled movements of the axis! Before assembly or disassembly: Make sure that the motor is switched off. Observe the safety notes in the operating instructions for the motor and axis. Make sure there are supplementary safety measures if a belt breakdown could be the cause of an injury. Note Observe the permitted tightening torques ( section 9). Clean the shafts. The clamping sleeves 3 and 4 only grip efficiently on dry and grease-free drive shafts. After disconnecting the motor or changing its position: Start a homing sequence for the axis. 2. Parts lists 2a.

Mounting of housing lower part 1 16335d_2 Select the thin O-ring aE ( table 9b). Push the O-ring aE onto the centering collar on the drive cover of the axis. Place the sealing rings aH onto the shaft of the screws aJ. Secure the lower part 1 to the axis by using all screws aJ. Select the thick O-ring aF ( table 9b). Lubricate the O-ring aF with lubricating grease dA. Push the O-ring aF onto the gear unit of the motor. 16335d_3 16335d_4 16335d_5a Place the adapter plate aC with the mounting hole on the gear unit. Secure the adapter plate aC to the plane surface of the gear unit by using the screws aB. 16335d_5b Press the O-ring aF over the nose (A) and into the groove of the adapter plate aC. Use a blunt tool when doing this. Avoid stretching the O-ring aF to prevent loops from forming. Place the seal aI on the adapter plate aC. 16335d_5c 16335d_17 For EAMM-U-...-D...-80G-S1: Place the additional seal bA in the recess of the lower part 1. When doing this make sure that the notches (X) and the drill holes (Y) are one above the other. 3) For EAMM-U-110/145, each counter bearing is attached with 2 screws cC. 4) For EAMM-U-110/145, the clamping component dB is needed as a tool. 16335d_6 Place the sealing rings aG onto the shaft of the screws 2. Attach the motor to the lower part 1 via the adapter plate aC by using all screws 2 and the square nuts 9. Tighten the screws 2 only lightly at first to ensure the motor can still be moved in the elongated hole. 4. Assembly of the toothed belt 5, toothed belt pulleys 6 and clamping sleeves 3/4 16335d_7 Push the motor towards the axis as far as its stop. Only lubricate the clamping sleeves 3/4 on the thread and cone by using lubricat- ing grease dA. This lubrication makes it easier to tighten the clamping sleeves 3/4 later and avoids stick-slip effects. Insert the clamping sleeves 3/4 into the toothed belt pulleys 6. Lightly turn the clamping sleeves 3/4 into the thread. Insert the toothed belt pulleys 6 into the toothed belt 5. Place the clamping sleeves 3/4 on the corresponding drive shafts. When tightening the toothed belt pulley 6, please note that the surface (B) must be aligned flush with the reference surface (C) on the lower part 1. At the start of tightening, the surface (B) should be approx. 1 mm above the reference surface (C), as the toothed belt pulley 6 moves inwards by this value during tightening. 16335d_8 Please note that the surface (B) has a different position depending on the size of the parallel kit. 60 86 110 15346d_9 16335d_9 Select the necessary tightening torque for the shaft-hub connection ( section 9c). Tighten the toothed belt pulleys 6 while simultaneously holding the clamping sleeves 3/4. Check whether the surfaces (B) of the toothed belt pulleys 6 are flush with the reference surface (C) of the lower part 1 (max. tolerance: ± 0.5 mm). 16335d_10 Otherwise, the toothed belt 5 or toothed belt pulley 6 will rub against the lower part 1 or upper part 7, which in both cases will result in premature wear or jamming. If the tolerance is exceeded: Lightly loosen the clamping sleeve. Readjust the toothed belt pulleys 6. 5. Clamping the toothed belt 5 In an untensioned status, the strands (D) of the toothed belt 5 are lightly arched. If necessary, loosen the screws 2 only so much that a relative movement between motor and lower part 1 is barely possible. Tension the toothed belt 5 only until both strands (D) run approximately parallel, that is, are no longer curved. Do this as follows: For EAMM-U-60/-86: – By moving the motor by hand with the specified clamping force Fv ( table). For EAMM-U-110: – By moving the motor using the clamping component dB as follows: 16334d_10 Place the clamping compo- nent dB 4) into the hole (E) in the lower part 1. Tighten the clamping com- ponent dB with a hexagon spanner ß 8 and the rec- ommended torque ( table).
