In the rack and pinion steering system, the accuracy and meshing degree of the steering rack are relatively important, and the steering system is an important assembly that determines the active safety of the car. Poor accuracy of the steering rack can cause insensitivity and unstable handling, requiring a significant rotation of the steering wheel, which not only affects the comfort of the car's operation, but can also lead to steering system malfunctions and accidents. The rack and pinion steering system is a commonly used steering mechanism in cars and small trucks, and the automotive steering rack is an important component of the rack and pinion steering system. Its working principle is simple. The rack and pinion gear set is wrapped in a metal tube, and each tooth end of the rack protrudes outside the metal tube and is connected together by a tie rod. A small gear is connected to the steering shaft, and when the car steering wheel is turned, the steering gear rotates, causing the

The advantage of helical teeth over straight teeth lies more in their smoothness of operation and the accompanying noise reduction effect, which is actually a misunderstanding. Below, we will introduce the difference between using straight teeth and helical teeth in rack and pinion transmission on engraving machines. From a theoretical analysis, helical teeth have a helix angle β Of course, this is a professional statement. In ordinary terms, it means that the tooth is crooked, while the straight tooth is straight. This is easy to understand. However, because the helical tooth has a spiral angle, the force area when biting is larger, and naturally, the bearing capacity is relatively stronger than that of the straight tooth. Of course, the difference between the two is not very significant. The advantage of helical teeth over straight teeth lies more in their smoothness of operation and the accompanying noise reduction effect

Rack and pinion oil pumps are commonly used to transmit oil substances, including gasoline, diesel, petroleum, etc. They play an important role in industrial production and are all liquids. During trial operation, if there is abnormal resistance, the machine should be stopped immediately for inspection. Continuously debug until it works properly. There are many factors that affect the use of oil pumps, and blockage of the oil pump is one of the common problems. Below, the rack and pinion manufacturer will analyze how to prevent gear oil pump blockage: 1. Internal problems in the rack and pinion oil pump can cause blockage. The rack and pinion oil pump is powered by the impeller to guide oil into the pipeline. Problems with the impeller or other components can cause problems with the filtration and transmission systems of the oil pump,

What are the working characteristics and process flow of precision rack quenching equipment? With these questions in mind, let's take a look at the following introduction. 1. Job characteristics: longitudinal and transverse composite magnetic field induction heating quenching: high heating efficiency, fast speed, only 6 seconds per piece; The hardened layer has a uniform hardness distribution. Low power consumption; The edge of the tooth surface is consistent with the middle. The hardened layer of the tooth root can be accurately controlled. The deformation is very small. 2. Working principle: Connect a high-frequency power supply, connect the electrical contacts of the inductor into a circuit, and the sample above the inductor becomes the induced heating element. In this way, the surface of the workpiece is not only heated by the longitudinal magnetic field, but also by the transverse magnetic field, thereby achieving the goal of uniform heating. Replacing different sensors can heat s

Nowadays, the demand for product quality is increasing, so high-precision mechanical parts are often chosen when using them. Precision racks are widely used in many industries due to their high precision and fast speed. So, how should we maintain precision racks as high-precision accessories. When maintaining precision racks, attention should be paid to the following points: 1. First, we need to confirm whether the lubricating oil we use is the appropriate rack oil in the rack. Not all lubricating oils are good for the rack. If you don't know how to use the appropriate lubricating oil, you can ask a professional. 2. To avoid excessive accumulation and blockage of lubricating oil, only apply oil to the key parts of the precision rack. After oiling, it will reduce the wear and noise during the operation of precision racks. 3. Only a small amount of lubricating oil needs to be used at other positions of the rack to prevent damage
