The shaft is an important part of the mechanical structure. It supports the rotation of other rotating parts (such as gears, pulleys, etc.) and transmits motion and power. At the same time, it is connected to the machine channel through bearings (rolling bearings and sliding bearings). All parts of the shaft 1 are rotated about the shaft, thereby forming a shaft-based assembled shaft assembly. In the design of the shaft, not only the shaft itself, but also the entire structure of the shaft system components must be tightly connected.

The drive shaft is a rotating body with high speed and little support, so its dynamic balance is very important. Usually, the drive shaft processing plant must undergo a dynamic balance test and adjust it on a balancing machine.Deep processing of drive shaftProcess steps:

1. First, drill a center hole at both ends of the forging blank, and use a few steps to rough the outer circle.

2. For tempering;

3. For each step of the semi-finished car, there is a margin for the outer circle and length, and then the middle frame car is taken to the total length;

4. The through hole on the drill pipe shaft on the center frame;

5.Deep processing of drive shaftDrill tapered holes at both ends, insert partitions at both ends, and drill holes in the center hole to prepare for polishing;

6. Fine turning the outer circle and step surface of each gear, plus grinding allowance, and cutting grooves and chamfering on the outer circle of the car;

7. Grind the outer circle and step plane of each gear to the appropriate size;

8. Machining each thread on this lathe after assembly.

Deep processing of drive shaftIncluding the following steps: forging, normalizing, rough turning, fine turning, deep hole drilling, hobbing, oil drilling, then pre-degreasing, degreasing, hot water cleaning, cold water cleaning, activation treatment, ultrasonic rinsing, chemical cleaning and drying a series of cleaning work.

If the quality of the drive shaft is not good, the serious consequence is that it will cause the drive shaft to break, making the car unable to drive, and directly causing serious problems. Therefore,Deep processing of drive shaftBe sure to pay attention to quality.
