The Bosch Rexroth BASE UNIT 90+ AL CURVE WHEEL (3842547381) is an essential component for material handling applications requiring precise and efficient movement of goods through curved conveyor systems. This base unit is designed to be used in conjunction with a drive kit to create a curve wheel drive, capable of propelling a conveyor chain in circuit systems with a top-running chain design. The unit's housing is constructed from die-cast aluminum, ensuring durability and longevity, while the chain wheel is made from white PA (polyamide), offering excellent wear resistance. The ball bearings are crafted from nonrusting steel and feature seals on both sides as well as an FDA-compliant grease filling, making this unit suitable for applications that require adherence to strict hygiene standards. The BASE UNIT 90+ AL CURVE WHEEL allows for the implementation of multiple superimposed basic curve wheel units in alpine conveyors through its integrated hexagonal hollow shafts. It boasts an effective sliding rail length and actual chain length tailored to specific requirements, with additional versions available upon request through Bosch Rexroth's modification department. The product comes with all necessary fastening materials but is delivered unassembled. For optimal performance, the use of recommended accessories such as the connection kit alpine conveyor and required accessories like the drive kit curve wheel, assembly module, and slide rail are advised. This model supports all suitable chain types and can handle a maximum permissible chain tensile force as well as torque, facilitating smooth conveying operations at recommended speeds. When multiple curve wheel base units are combined, it's crucial to ensure that motor torque is evenly distributed across each level. The innovative drive concept enhances the overall functionality of conveyor systems while maintaining low noise levels during operation. It should be noted that accumulation operation should not occur until a certain distance after the curve wheel drive and that this unit must only be utilized with closed profile systems for safety and efficiency.

BASE UNIT 90+ AL CURVE WHEEL

Base unit KRA AL VFplus 90

Unpacked Weight: 5.6 kg

Side elements with slot to attach holders for lateral guides, or similar

The curve wheel drive is used for driving the conveyor chain in circuit systems with a top-running chain. Combining the base unit curve wheel 180° AL with the appropriate drive kit quickly turns it into a curve wheel drive.

Size: 65 and 90 Suitable chain types: all Permissible chain tensile force: Fmax = 400 N per level, section length for closed circuits: L ≤ 10 m Permissible torque: Mmax = 60 Nm

When combining several curve wheel base units, the motor torque must be distributed across the individual levels

Conveying speed: vN = 4-21 m/min

For drives with frequency converters (FU), the speed is to be limited to a maximum of 21 m/min by a control system

Recommendation: no accumulation operation until 1000 mm after the curve wheel drive Can only be used with a closed profile
