About Journal Bearing Apparatus

Journal Bearing Apparatus

The apparatus consists of a plain steel shaft excavated in a bearing and directly driven by a FHP Motor. The bearing is freely supported on the shaft and sealed at the motor end. The speed of the motor is controlled accurately by the speed control unit and it can be made run in both directions. Twelve equal-spaced pressure taping around the circumference and four along the axis are provided and are connected to manometer by PU Tubing so that the pressure head of oil in all tubes can be observed at a time. The bearing can be loaded by attaching weights to the arm supported beneath it.

Experiments

To study the pressure profile of lubricating oil at various conditions of load and speed
Plotting the Cartesian polar pressure curves
To measure the frictional torque and power transmit

Utilities Required

Electric supply : 230 V AC, Single Phase.
Bench area : 1.5 x 1.5 x 4 m
Tachometer to find out RPM of journal
Oil SAE 40 about 5 Ltrs.

Advanced Construction and Materials

The apparatus combines a powder-coated mild steel body for durability and stability with a high-quality bronze bearing for reliable performance. All included accessories, such as the specimen journal and oil funnel, support user convenience and safe operations during laboratory experiments.

Efficient and Safe Operation

Equipped with an electric motor drive, overload protection, and a splash guard, this journal bearing tester operates smoothly and safely at variable speeds. Manual controls ensure user-friendly testing, while the viewing window enables real-time oil film visualization for detailed study.

Precision in Measurement and Testing

The apparatus offers a measuring range of 0-50 N with up to 1% accuracy and a 0.1 N resolution. It features both analog and digital readouts with less than two seconds response time, providing immediate and reliable results for teaching or research applications.

FAQs of Journal Bearing Apparatus:

Q: How is the Journal Bearing Apparatus used in a laboratory setting?

A: This apparatus is typically used in Theory of Machine labs to study the behavior and performance of journal bearings under varying load, speed, and lubrication conditions. Users install the specimen, adjust the speed and load parameters manually, and observe the oil film through the viewing window while collecting data from the built-in display.

Q: What are the main benefits of choosing a bronze bearing with splash lubrication?

A: Bronze bearings provide excellent wear resistance and compatibility with lubricants, making them ideal for repeated laboratory tests. The splash lubrication system ensures consistent oil distribution, reducing friction and heat without requiring complex maintenance.

Q: When should I visually inspect the oil film pattern on the apparatus?

A: A visual inspection of the oil film pattern should be performed before, during, and after testing to ensure optimal lubrication and to observe any changes in bearing performance under various speeds and loads. The built-in viewing window makes this process straightforward and safe.

Q: Where can the Journal Bearing Apparatus be installed?

A: Designed as a bench-top unit, the apparatus can be mounted securely on any solid laboratory table with access to a standard 230V AC power outlet. Its compact footprint and splash guard design keep the workspace organized and safe.

Q: What is the process for conducting a test with the Journal Bearing Apparatus?

A: Begin by setting up the specimen in the apparatus, filling the oil bath, and powering the motor. Adjust the load and speed as needed. Watch the oil film via the viewing window while gathering load readings. After your test, record the data from the analog or digital display for analysis.

Q: How accurate and responsive are the measurement systems on this equipment?

A: The apparatus provides direct load indication with a measurement accuracy of 1% and resolution to 0.1 N. Readouts update in less than two seconds, ensuring prompt observation of changes during the test.

Q: What additional features enhance the safety and usability of this apparatus?

A: Key features include overload protection to safeguard both specimen and user, a splash guard to contain lubricant, and straightforward manual controls. Included accessories like the instruction manual and oil filling funnel further simplify operation and maintenance.
