June 3 is Sunday; a farmer brother from Sa Town, Huocheng County, calls the phone; it is said that his tractor has been produced by spring plowing; the end bearing of the rear axle power output shaft has been damaged 2 sets; now it is busy in summer. Period; this is not; the bearing is hot, and there is an abnormal sound; according to the experience; the damage can be immediately; take this opportunity; I want to let him tell him where the problem lies.
The intuitive tractor is connected with the power output shaft of the driving cymbal; it is composed of two universal joint assemblies to form an external transmission shaft. The outer fork/internal fork of the two universal joints are not on the same plane; according to the working principle of the universal joint; This is definitely the main reason for the frequent damage of the end bearing of the power output shaft on the rear axle housing.
The function of the universal joint shaft is to connect two shafts with different hearts. It is mainly composed of a cross fork, an inner fork, an outer fork, etc. When the device is connected; the outer fork/internal fork of the two universal joints must be separated. On the same plane; as long as this; the unbalanced centrifugal forces that occur in the rotation of the two gimbal forks cancel each other out; to reduce the additional load on the bearing of the universal joint shaft; to extend the service life of the end bearing of the drive shaft. I must grasp this little trick.
