Reductor XC

Product catalog summary

1. Overview of X Series Worm Gearboxes

The X series worm gearboxes come in three main versions: XA (shaft-mounted), XF, and XC (motor mounting). The XF version, equipped with a bell and coupling, offers higher efficiency and flexibility, while the compact XC version is optimized for space-saving applications. Housing materials vary by size: cast iron for sizes 90, 110, and 130, and die-cast aluminum for smaller sizes. The worm shaft is made from case-hardened, ground alloy steel, and the worm wheel features a cast iron hub with a cast bronze ring. Cast iron housings are painted blue (RAL 5010), and aluminum housings are sandblasted. A hollow output shaft is standard, with numerous accessories available such as second inputs, tapered roller bearings, output flanges, extended shafts, torque limiters, torque arms, and protection kits.

2. Designation and Versions

Gearboxes are identified by input type and size, with multiple mounting positions and flange options. Detailed coding facilitates selection based on specific application requirements, including motor coupling and mounting configurations.

3. Lubrication and Mounting Positions

Except for size 130, gearboxes are supplied with synthetic PAG lubricant (ISO VG320). Specifying the mounting position at order is critical to ensure proper lubrication and performance. Smaller aluminum housings (sizes 30 to 75) have a single oil filling plug. Detailed tables specify oil quantities per size and mounting position, along with locations for filling, breather, level, and drain plugs.

4. Terminal Board Position

The terminal board position must be specified when ordering to guarantee correct electrical connection and installation orientation. Reference is made to detailed terminal board positions (PM=1; PM=2) documented on pages 33-34.

5. Technical Data and Performance Parameters

Comprehensive tables provide data for input speeds of 2800, 1400, 900, and 500 rpm across sizes 30 to 130. Key parameters include reduction ratio (Rd), rated torque (T2), power ratings (P, P1), and service factors (FS’). Maximum allowable torque (T2M) is calculated as T2 multiplied by FS’. Data covers XC and XF versions with various flange types (B5, B14) and mounting configurations. Power ratings range from fractions of a kilowatt to several kilowatts depending on size and speed. Efficiency values and moments of inertia are also provided for precise engineering calculations.

6. Additional Features and Accessories

Options include additional inputs (double extended shafts), torque limiters with through hollow shafts, torque arms, and protection kits. These enhance adaptability and safety in diverse industrial applications.

7. Torque Limiter with Through Hollow Shaft

The torque limiter protects machinery by limiting transmissible torque, integrating a friction clutch within the gearbox. It operates in an oil bath for reliability and wear resistance but is not compatible with tapered roller bearings or prolonged slipping. Calibration is externally adjustable via a self-locking ring nut compressing Belleville washers. Slipping torque varies with load conditions and decreases over time due to wear, necessitating regular calibration checks. Devices are supplied pre-calibrated to catalog torque values unless otherwise specified.

8. Technical Specifications and Dimensions

Detailed dimensional data is provided for flange types (XA, XC, XF) and IEC standards (IEC 90, 100-112, 132) across sizes 30 to 130. Parameters include shaft diameters, flange thicknesses, bolt hole sizes, and mounting dimensions with precise tolerances (e.g., j6, H7, h8). Hybrid flange combinations are possible, with PM=2 mounting recommended only if PM=1 is not feasible.

9. Calibration and Torque Testing

Periodic calibration verification is recommended, especially during the break-in phase. For applications requiring tighter accuracy, transmissible torque testing on the system is advised. Torque limiters are delivered calibrated to catalog torque values unless otherwise specified.

10. Accessories and Spare Parts

Available accessories include single and double output shafts, torque arms, protection kits, optional tapered roller bearings, hollow shafts, and torque limiters with detailed dimensional specifications. The spare parts list covers bearings, oil seals, and closed oil seals for sizes 30 to 130, with standard bearing numbers and optional tapered roller bearings available on request.

Critical Information and Best Practices

Always specify mounting position and terminal board location when ordering to ensure correct lubrication and installation.
Calculate maximum allowable torque using the provided service factor to prevent overloading.
Select the appropriate gearbox version (XA, XF, XC) based on efficiency, space constraints, and motor coupling needs.
Consult detailed technical tables for power, torque, and speed ratings to choose the correct size and configuration.
Use available accessories to customize gearboxes for specific operational and protection requirements.
Torque limiters must not be used with tapered roller bearings or for prolonged slipping operations.
Regular maintenance and calibration checks of torque limiters are essential for performance and longevity.
Hybrid flange combinations are feasible; PM=2 flange mounting is recommended only if PM=1 is not possible.
