बेअरिंग (Bearing ) नंबर की पहचान / किसी भी बेअरिंग नंबर से उसका प्रकार पहचाने और उसके ID इनर diameter कितना होगा पता करे

दोस्तों नमस्कार !

आप सभी इंजीनियर अपने उद्योग कार्यो के दौरान पाया होगा की हर 10 में से 8 मशीनों में बीयरिंग पाया जाता हैं। बेअरिंग हमारी इंजीनियर क्षेत्र मई एक महत्वपूर्ण खोज है।
आप सभी ज़्यादातर मेंटेनन्स कार्यो के दौरान मशीन के बेअरिंग की जांच ज़रूर करते होंगे। मशीन की कार्यक्षमता को बिना किसी रुकावट के कार्य करने के किये यह अति आवश्यक है की हम उसमे लगे बेअरिंग की जांच अच्छे से करे। यदि हम बेअरिंग का रखरखाव अच्छे से करते है तो हमारी मशीन की कार्यक्षमता बढ़ती डाउंटाइम कम होता है और मशीन के रखरखाव में होने वाले खर्च में भी बचत होती है।

मैं आपको बीयरिंग नंबर से उसका प्रकार और ID inner diameter असर करने के तरीके के बारे में जानकारी दूंगा, लेकिन शुरू करने से पहले आपको असर का अर्थ पता होना चाहिए

एक असर एक मशीन तत्व है जो केवल वांछित गति के सापेक्ष गति को रोकता है, और चलती भागों के बीच घर्षण को कम करता है। असर का डिजाइन, उदाहरण के लिए, चलती हिस्से के नि: शुल्क रैखिक आंदोलन या एक निश्चित अक्ष के चारों ओर मुक्त रोटेशन के लिए प्रदान कर सकता है; या, यह सामान्य बलों के वैक्टर को नियंत्रित करके गति को रोक सकता है जो आगे बढ़ने वाले भागों पर होते हैं। अधिकांश बीयरिंग घर्षण को कम करके वांछित गति की सुविधा प्रदान करते हैं।

अब असर के प्रकारों को जानने और समझने के लिए वापस जाएं। नीचे उल्लिखित कुछ सामान्य प्रकार के असर हैं जो आमतौर पर दिन मशीनों के लिए उपयोग किए जाते हैं:

Complete Selection & Identification guide for Power transmission V-Belts

In maintenance field you must be familiar with the terms V-Belts. V-Belts are the most common way to transmit power from one shaft to other.

Motor driving pump with the help of V-Belt

A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

V-belt

Its very important to select right V-Belt for specific application, Also to avoid the frequent failure of V-belts its very important to check the alignments fo belts at the time of mounting.

Its very important to keep in mind that power is transmitted through friction between belt wedges & Pulley side wedges.

Now, Lets under stand the V-Belts nomenclature system, for this lets take example of V-Belt of B-84,

Where B is the section of Belt, having standard Top width & Thickness

Section of V-Belt in Inches

Section of V-Belt in mm.

Power Transmission Couplings:

Whats are Power Transmission Couplings & their uses:

Defination:

A coupling is device used to connect two shafts together at their ends for the purpose of power transmission.
It also acts as a fuse between driver (Motor) & Driven (Gear box, Crusher, etc), as it get disconnected at the time when the transmission power exceeds the coupling designed capacity.

Motor & Pump connected through coupling

Requirement for Coupling & its function:

Accommodates misalignment.(i.e Parallel/Radial, Axial, Angular misalignment).
Dampen Vibration (by absorbing Shocks), Oscillation.
Limiting power & torque transmission.

Types of shaft misalignment

Types of couplings commonly used in Industries:

Decoding bearing Number/ Identifying bearing number by measuring the bearing with the help of Mobile application

Hello guys,

In daily maintenance task you must have encountered bearing with missing bearing number due to breaking, wearing of bearing with time or might found some serial number mentioned from the machine OEM which dose not have any relation with bearing nomenclature. These decoded bearing from OEM will cost you more than the normal bearing available in reputed brands like SKF Bearing, FAG Bearings, TIMKEN Bearings Etc, Where you can get them easily by telling the bearing number.

We can easily found the bearing number with the help of Bearing Catalog app available in GOOGLE Play store simply by measuring the bearing with the help of vernier scale.

Just measure & note down the three parameters of the bearing i.e

Inner Diameter of bearing.
Outer Diameter of bearing.
Thickness of bearing.

Lets take some random side,

ID of bearing - 40.
OD of bearing - 80.
Thickness of bearing 23.

Just download the app or Click on the app image to get the download link

Download the bearing finding app

Input the bearing size i.e the ID & OD of bearing & click on search button.

Now you will get the list of sevral bearing having 40mm ID & 80mm OD, You just have to match the thickness or breadth of the bearing to identify the right bearing number

Hope this content will help you with the selection of right bearing for your desired application & understanding the bearing naomenclature will help you to select right bearing for your application.

Guide to Selection / Identification of bearing Number

Guide to Selection of Bearing / Identification of bearing Number

In industries many of us encounter the term Bearing in maintenance field, Possibly 8 out of 10 machines have bearings in it.
While maintenance/overhaul of machines its very necessary to check the condition of bearings to extend the life of machines, Proper selection of bearings & lubricating of bearings is very necessary to reduce the downtime & avoid delays in timely execution of the designated task.

I will be briefing you to Types of bearing and ways to Identify the bearing number, but before starting lets know the meaning of bearing

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction.

Lets now get back to know & understand the types of bearing. Below mentioned are some common types of bearing used commonly in day to day machines:

Deep Groove Ball Bearing.
Self Aligning Roller Bearing.
Cylindrical Roller Bearing.
Tapered Roller Bearing.
Thrust Bearing.
Angular Contact Ball Bearing.
Needle Roller Bearing.
Self Aligning Ball Bearing
Miniature of Bearing.

Each bearing you encounter have some Number engraved on their Outer or Inner raceway for example Bearing Number "6210" Also called as bearing nomenclature, each number will have a particular meaning in its own way.

Lets now try to understand or learn to crack this nomenclature. Lets take bearing Number "6208 ZZ C3"

First Numeric will tell you the Type of Bearing for this it is "6" which is designated for Deep Groove Ball Bearing.
Second Numeric value will tell the dimensional series for this it "2" which is designated for Dimensional series 2.
Last two numeric value will tell you about the Inner Diameter of the bearing or Shaft Outer Diameter when it is multiplied with 5 in which bearing is to be mounted, for this its "08" now when 08 is Multiplied with 5 gives 40 - Approximately the ID of bearing will be 40mm.
Succeeding alphabetic will tell us about the side casing of bearing, for this it is ZZ which means the inner of the bearing is covered with Metallic Cover, Where 2RS or RS stands for rubber covering, This type of bearing are suitable for application where bearing has to perform under heavy dust environment.
Further after covering notation there is nomenclature for bearing clearance, Here notation for bearing clearance is C3, Higher the C Value more the clearance between the inner & outer raceway, High value clearance bearing are suggested where the bearing has to perform under heavy vibration or Temperature to avoid breaking of bearing because of vibration or seizure of bearing due to expansion of bearing metal because of Temperature.
