In modern automobile manufacturing, the precision and efficiency of parts are the key to ensuring stable vehicle performance and comfortable driving experience. Among them, automotive parts gears and lead screw drive modules are the core components of the transmission system, and their design and manufacturing level is directly related to the power transmission efficiency, running stability and service life of the vehicle. This article will explore in depth the customized design of automotive parts gears, especially dual gears, as well as the various types and characteristics of lead screw drive modules.1. Automotive parts gears: customized design of dual gears1. Gear overviewAutomotive parts gears are an important part of the automobile transmission system, used to transmit torque and change speed. The design of gears needs to consider material selection, heat treatment process, tooth shape accuracy and other aspects to ensure their high strength, wear resistance and low noise.2. Dual gear customized designDual gear design is usually used in gearboxes to achieve smooth switching between different speed ratios. According to the overall reduction ratio requirements of the gearbox, the number of teeth, module, helix angle and other parameters of the dual gears can be customized. This customized design can not only meet the power requirements of the car under different working conditions, but also improve transmission efficiency and reduce energy consumption.Tooth number customization: By adjusting the tooth number ratio of the dual gears, different reduction ratios can be achieved to adapt to the power requirements of the car at different speeds.Modulus customization: The modulus determines the pitch and tooth height of the gear. By adjusting the modulus, the strength and load-bearing capacity of the gear can be changed.Helix angle customization: The design of the helix angle can affect the meshing performance and noise level of the gear. Reasonable helix angle design can reduce meshing impact and improve transmission stability.3. Application advantages of dual gearsImprove transmission efficiency: Through precise customized design, dual gears can achieve more efficient transmission and reduce energy loss.Enhance load-bearing capacity: Reasonable gear parameter design can improve the strength and wear resistance of the gear and extend its service life.Reduce noise: Optimized tooth shape and meshing design can reduce the noise when the gear meshes and improve the driving experience.2. Screw drive module: diversity and efficiency coexist1. Overview of screw drive moduleThe screw drive module is a transmission device that converts rotational motion into linear motion. It is widely used in automobiles, machine tools, automation equipment and other fields. There are various types, including self-locking screws, sliding screws and high-efficiency transmission screws.2. Self-locking screwsSelf-locking screws have a self-locking function and can maintain the same position without external force. They are suitable for occasions that require precise positioning and large loads. However, the transmission efficiency of self-locking screws is relatively low, and they are suitable for scenes with low requirements for transmission efficiency.3. Sliding screwsSliding screws have large friction and low transmission efficiency, but they have a simple structure and low cost. Sliding screws are suitable for occasions with low requirements for transmission accuracy and axial stiffness, such as some simple positioning or transmission tasks.4. High-efficiency transmission screws (ball screws)Ball screws are the representative of high-efficiency transmission screws, and their transmission efficiency can generally reach 90%-96%. Ball screws are composed of screws, nuts, steel balls, etc., and high-efficiency transmission is achieved by rolling the steel balls between the screws and nuts. Ball screws have the advantages of good wear resistance, long life, high precision, and high rigidity, and are widely used in precision machinery and automation equipment.High transmission efficiency: The transmission efficiency of ball screw is much higher than that of sliding screw, which can reduce energy loss and improve system efficiency.High precision: The transmission accuracy of ball screw can reach thousands of inch per foot, which is suitable for high-precision transmission and positioning tasks.Strong rigidity: By appropriately applying preload to the balls, the ball screw can obtain higher rigidity, improve the stability and load capacity of the system.As the core component of the automobile transmission system, the design and manufacturing level of the automotive parts gear and screw transmission module has an important impact on the performance of the automobile. The customized design of the double gear can meet the power requirements of the automobile under different working conditions and improve the transmission efficiency; while the screw transmission module provides more choices for the automobile transmission system with its diversity and efficiency. In the future automobile manufacturing, with the continuous development of materials science, manufacturing technology and intelligent technology, the performance of the automotive parts gear and screw transmission module will be further improved, contributing to the sustainable development of the automobile industry.
