Alfalfa grass harvester is a kind of agricultural machinery and equipment used to harvest alfalfa grass, and its energy and efficiency directly affect the effect of agricultural production. In the process of using alfalfa grass harvester, the adjustment of the clutch is a very important part, which is related to the normal operation and service life of the harvester. The following is a detailed introduction to the adjustment method of the clutch of the alfalfa grass harvester.
Understand the role of the clutch: The clutch is a device that connects the engine to the drive wheels, and its main role is to cut off or transmit power when starting, stopping, and shifting. The main components of the clutch include clutch disc, pressure plate, release bearing, etc.
2.Check the working status of the clutch: Before adjusting the clutch, first check the working status of the clutch, such as whether the clutch is slipping, incomplete disengagement, etc. If a problem with the clutch is found, it should be repaired or replaced in time.
3.Adjust the clearance of the clutch: The clearance of the clutch refers to the small distance between the clutch disc and the pressure plate. Too much clearance will cause the clutch to slip, and too little clearance will cause the clutch to disengage incompletely. The clearance of the clutch should be kept at 05-1.5mm. The method of adjusting the clutch clearance is to adjust the position of the release bearing with a special tool, so that the distance between the clutch disc and the pressure plate reaches a suitable range.
4.Adjust the free stroke of the clutch: The free stroke refers to the distance between the clutch disc and the pressure plate when the clutch pedal is not subjected to external force. Too much free travel will cause the clutch to disengage completely, and too little free travel will cause the clutch to slip. The free stroke of the clutch should be kept between 10-15mm. The way to adjust the free stroke of the clutch is to adjust the position of the disengaged bearing with a special tool so that the distance between the clutch disc and the pressure plate reaches a suitable range.
5.Adjust the working pressure of the clutch: The working pressure of the clutch refers to the contact pressure between the clutch disc and the pressure plate. Too much working pressure will cause the clutch to wear out too quickly, and too little working pressure will cause the clutch to slip. The working pressure of the clutch should be kept at 05-1.5MPa. The way to adjust the working pressure of the clutch is to adjust the oil pressure of the clutch master cylinder.
6.In the process of adjusting the clutch, it is necessary to pay attention to keeping the clutch clean to prevent dust and impurities from entering the clutch and affecting the normal operation of the clutch.
