How to Solve the Squeaking Noise in Verna Clutch?
1 Answers
Verna clutch squeaking noise is caused by damage to the release bearing, and related components need to be replaced. The function of the clutch is to ensure smooth starting and seamless gear shifting of the vehicle. The clutch is located inside the flywheel housing between the engine and the transmission, with the clutch assembly fixed to the rear plane of the flywheel by screws. The output shaft of the clutch is the input shaft of the transmission. The following are relevant precautions for the clutch: 1. The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris. 2. The clutch can be installed coaxially or on separate shafts. The axial direction must be fixed, and axial movement is not allowed for both the driving and driven parts. When installed on separate shafts, the coaxiality between the driving and driven shafts should not exceed 0.1mm. 3. For wet electromagnetic clutches, lubricating oil must be added between the friction plates during operation. The lubrication methods include: (1) Splash lubrication. (2) Oil bath lubrication, where the immersed part should be approximately 5 times the volume of the clutch. (3) Axial oil supply lubrication, which should be used for high-speed and high-frequency operations. 4. When installing a jaw-type electromagnetic clutch, a certain gap must be ensured between the end teeth to prevent grinding during idling, but the gap should not exceed the δ value. 5. Electromagnetic clutches and brakes are Class B insulated, with a normal temperature rise of 40°C. The operating temperature during extreme thermal balance should not exceed 100°C, otherwise the coils and friction parts are prone to damage. 6. For power supply and control circuits, the clutch power supply is DC 24V (except for special orders). It is obtained by reducing three-phase or single-phase AC voltage and full-wave rectification (or bridge rectification), without the need for voltage stabilization or smoothing, but the power must be sufficient. Half-wave rectification power supply is not allowed.
