Product catalog summary
Terms and Conditions: Deliveries and services adhere to established terms. Claims on goods must be written within 8 days of receipt. Prices are ex-factory, excluding packaging, and invoiced at delivery day prices plus VAT.
Product Overview: The document covers products like shaft mounted gearboxes, geared motors, and electric motors, detailing descriptions, unit designations, mounting configurations, and drive selection methods.
Product Descriptions: Rehfuss gearboxes and motors are designed for continuous operation with helical gears for quiet performance and robust cast iron housings. Various drive combinations, including electronic variable speed drives, are possible.
Unit Designation: A coding system identifies product types, sizes, and configurations, including options for solid and hollow shafts, flange mounting, and free input shafts.
Mounting Configurations: Details on mounting positions and terminal box locations are provided, with specific configurations required for brake motors.
Drive Selection: Load classifications and permissible service factors guide drive selection, with tables for service factors based on running time, ambient temperature, and load classification.
Specifications and Service Factors: Operational conditions are crucial for selecting the correct drive system. Service factors, influenced by load type and operating conditions, affect gearbox size but not motor power.
Load Classifications: Three classifications are outlined based on mass acceleration factors, suitable for different operational demands from light conveyors to heavy presses.
Radial and Axial Loads: Permissible loads for gearbox shafts are approximate, with combined forces reducing radial force. Transmission elements require specific factors for radial force calculation.
Motors and Brake Motors: Motors comply with DIN EN 60034 standards, featuring IP 55 protection and standard voltages. Brake motors have electromagnetic brakes, increasing motor length, and non-reverse stops.
Temperature and Electrical Protection: Motors have temperature-sensitive resistors for protection, with relays for control and fault detection. Current-sensitive protection is limited, and frequency inverter drives offer partial protection.
Thermal Protection: Automatic thermal triggers and pyrometric sensors provide integral protection, reacting to temperature changes.
Brake Motors: Spring-loaded brakes convert motors to brake motors, with adjustments for air gap and torque. Electrical and mechanical lifting options are available.
Technical Data: Detailed specifications for brake types include torque, speed, coil rating, and permissible wear.
Technical Document Summary:
1. Specifications and Units: Units include Nm, J, ms, J/s, N, kW, m, and kgm2, with rotational speed in min-1.
2. Switching Times: Parameters for rapid and delayed braking include closing delay, switch-off time, and nominal torque.
3. Braking System Connection: Describes AC and DC side switching for braking, with fast excitation units available.
4. Rectifiers: Standard brake motors use bridge rectifiers, with examples for different supply voltages.
5. Control of High-Frequency Drives: Methods to align motor and brake response times include micro switches and time relays.
6. Power Tables: Selection tables for geared motors detail input power, output speed, torque, and service factors.
Overview: Technical specifications for Rehfuss Constant geared motors cover configurations like basic mounted and flange mounted designs.
Specifications: Dimensions and configurations for gear units FG 210 to FG 260 are detailed, with measurements for components like output shafts.
Standards and Keyways: Keyways and tapped center holes follow DIN standards for compatibility and precision.
Weight and Dimensions: Approximate weights and detailed dimensions for motor components are provided.
Technical Drawings: Illustrations are non-binding and subject to change, advising verification before finalizing designs.
Recommendations: Users should verify specifications due to potential technical changes.
Specifications: Gear unit specifications include dimensions and technical details, with designs Z and D focusing on general dimensions and torque arms.
Rubber Buffers: Available upon request, with specific dimensions provided.
Technical Notes: Illustrations and dimensions are non-binding and subject to change.
