Interpreting Flender Gearbox Identification Marks: A Practical Guide for Engineers
(how to read flender gearbox tag)
Exact recognition of industrial gear devices is vital for maintenance, purchase, spare parts getting, and making certain functional safety and security and performance. Flender transmissions, widely acknowledged for their robustness and application in demanding industries, make use of standard recognition tags fastened directly to the equipment system housing. Comprehending just how to analyze this info is a fundamental skill for mechanical designers entailed with these assets. This post outlines the essential parts commonly located on a Flender transmission tag and their significance.
The main resource of information is the steel nameplate, generally secured to the leading or side of the transmission case. Find this tag; it has the essential data encoded in alphanumeric strings. The most crucial aspects include:
1. Gear Device Kind Classification: This is the core identifier. It complies with a particular Flender coding system defining the transmission design, dimension, and series. Instances include “B3SH10”, “K87”, or “FZG.FA.”. The structure shares info concerning the gear plan (e.g., identical shaft, bevel-helical), placing setup (e.g., foot-mounted, flange-mounted), and the nominal size within the series. Referencing Flender’s current or historical technical paperwork corresponding to the transmission’s era is essential for a precise breakdown of this code. Misconception below can cause inaccurate extra components or application presumptions.
2. Identification Number (S/N): This one-of-a-kind identifier is crucial for traceability. It links the certain transmission device back to Flender’s production records. When speaking to Flender or authorized service partners for technological support, guarantee cases, or specific paperwork demands, offering the total identification number is compulsory. It enables access to the exact develop requirements, including materials, lubricating substances utilized originally, and any special manufacturing notes applicable to that unit.
3. Equipment Ratio (i): Shared numerically (e.g., i= 24.76, i= 5.00), this shows the proportion between the input rate (normally the greater rate shaft) and the output speed (the reduced speed shaft). It is calculated as Input RPM/ Outcome RPM. Verifying the real proportion against the driven devices needs is vital during installment, repairing performance issues, or when changing electric motors or driven components. An inequality can result in overload, underperformance, or premature failing.
4. Input Speed (n1): Typically specified in changes per minute (RPM), this suggests the nominal rotational rate at which the gearbox is made to be driven by the prime mover (e.g., electrical motor). This worth, integrated with the equipment proportion, establishes the output rate. Going beyond the ranked input speed can create tragic damages as a result of excessive centrifugal pressures or lubrication failing.
5. Solution Variable (SF or fB): This is a multiplier put on the small input power rating of the gearbox. It accounts for the severity of the operating problems, consisting of the driven machine’s tons attributes (e.g., attire, moderate shock, heavy shock), daily operating hours, and environmental factors. A service variable above 1.0 indicates the gearbox is derated for the particular application compared to its nominal rating. Recognizing the used solution aspect is crucial when assessing if a transmission is suitable for a customized procedure or raised tons needs. Never ever assume a gearbox can take care of loads considerably beyond its rated capability multiplied by its service factor.
6. Nominal Power Ranking (P): Often specified in kilowatts (kW) or horse power (HP), this indicates the mechanical power the gearbox is developed to transmit at the rated input speed and under basic problems. Crucially, this rating is valid only for the particular solution variable (fB) specified on the tag. A gearbox rated for 100 kW at fB= 1.4 can not take care of 100 kW at fB= 1.0. Constantly cross-reference power, speed, and service factor.
7. Outcome Torque (M2): Generally given up kilonewton meters (kNm), this specifies the optimum acceptable torque on the output shaft under the ranked problems. This is a vital specification for sizing couplings and ensuring the driven devices shaft and parts can hold up against the transmitted pressure.
8. Lubrication Information: The tag usually defines the type and quantity of lube called for (e.g., ISO VG 220 mineral oil, 14 litres). Adherence to the defined lube kind, viscosity quality (VG), and fill degree is non-negotiable for accomplishing design life and dependability. Utilizing inaccurate lubricant is an usual source of premature bearing and gear failing.
9. Manufacturing Day/ Year: Gives context for the gearbox’s generation, aiding in discovering appropriate paperwork or comprehending potential obsolescence concerns.
Important Factors to consider: .
Tag Condition: If the tag is illegible, damaged, or missing, procedure ought to discontinue instantly. Contact Flender technological assistance with any type of available information (physical location, close-by equipment numbers, pictures) to try recognition. NEVER operate a gearbox without a readable recognition tag.
Paperwork: Always consult the original Flender documents (Basic Plan illustration, Information Sheet) corresponding to the identification number and kind designation. This offers comprehensive details on dimensions, weights, mounting, lubrication systems, acceptable pressures, and upkeep procedures far past the tag information.
Modifications: If the transmission has been modified (e.g., retrofitted with different bearings, seals, or auxiliary drives), the initial tag may no longer completely mirror the unit’s present capacities or needs. Look for documents for any type of alterations.
Online Resources: Use Flender’s online assistance websites and paperwork libraries, which usually enable searching by serial number or kind designation for the latest details and drawings.

To conclude, the Flender gearbox recognition tag is the basic trick to comprehending the system’s capacities, specifications, and upkeep requirements. Mechanical designers should excel in extracting and analyzing the type designation, serial number, ratio, rates, solution factor, power, torque, and lubrication data. This expertise creates the bedrock of responsible transmission management, guaranteeing secure procedure, reliable upkeep preparation, exact spare components purchase, and educated choices regarding repair service or substitute. Always focus on getting in touch with official Flender documentation for definitive specifications.
