如何选择变速箱

驾驶车辆时，变速箱负责提供牵引力和速度。低速挡提供最佳牵引力，高速挡提供最高速度。根据驾驶情况选择合适的挡位，可以最大限度地发挥牵引力和速度的优势。合适的挡位会根据路况、载重和速度而变化。低速挡可以加快加速，高速挡可以提高最高速度。但是，在驾驶之前，您应该了解如何使用变速箱。

功能

The function of the gearbox is to transmit rotational energy to the machine’s drive train. The ratio between input and output torque is the ratio of the torque to the speed of rotation. Gearboxes have many different functions. A gearbox may have multiple functions or one function that is used to drive several other machines. If one gear is not turning, the other will be able to turn the gearbox. This is where the gearbox gets its name.
The pitch-controlled system has an equal number of failure modes as the electrical system, accounting for a large proportion of the longest machine downtime and halt time. The relationship between mechanisms and faults is not easily modeled mathematically. Failure modes of gearboxes are shown in Fig. 3. A gearbox’s true service life is six to eight years. However, a gearbox’s fault detection process must be developed as mature technology is required to reduce the downtime and avoid catastrophic incidents.
A gearbox is a vital piece of machinery. It processes energy produced by an engine to move the machine’s parts. A gearbox’s efficiency depends on how efficiently it transfers energy. The higher the ratio, the more torque is transferred to the wheels. It is a common component of bicycles, cars, and a variety of other devices. Its four major functions include:
In addition to ensuring gearbox reliability, a gearbox’s maintainability should be evaluated in the design phase. Maintainability considerations should be integrated into the gearbox design, such as the type of spare parts available. An appropriate maintenance regime will also determine how often to replace or repair specific parts. A proper maintenance procedure will also ensure that the gearbox is accessible. Whether it is easy to access or difficult to reach, accessibility is essential.

目的

A car’s transmission connects the engine to the wheels, allowing a higher-speed crankshaft to provide leverage. High-torque engines are necessary for the vehicle’s starting, acceleration, and meeting road resistance. The gearbox reduces the engine’s speed and provides torque variations at the wheels. The transmission also provides reversing power, making it possible to move the vehicle backwards and forwards.
Gears transmit power from one shaft to another. The size of the gears and number of teeth determine the amount of torque the unit can transmit. A higher gear ratio means more torque, but slower speed. The gearbox’s lever moves the engaging part on the shaft. The lever also slides the gears and synchronizers into place. If the lever slips to the left or right, the engine operates in second gear.
Gearboxes need to be closely monitored to reduce the likelihood of premature failure. Various tests are available to detect defective gear teeth and increase machine reliability. Figure 1.11(a) and (b) show a gearbox with 18 teeth and a 1.5:1 transmission ratio. The input shaft is connected to a sheave and drives a “V” belt. This transmission ratio allows the gearbox to reduce the speed of the motor, while increasing torque and reducing output speed.
说到减速，齿轮箱是降低电机扭矩最常用的方法。扭矩输出与电机的体积成正比。例如，一个小型齿轮箱可以产生与一台输出转速相同的大型电机一样大的扭矩。反之亦然。目前有混合驱动和直列式齿轮箱。无论采用哪种类型，了解齿轮箱的功能将有助于您为特定应用选择合适的齿轮箱。

应用

When selecting a gearbox, the service factor must be considered. Service factor is the difference between the actual capacity of the gearbox and the value required by the application. Additional requirements for the gearbox may result in premature seal wear or overheating. The service factor should be as low as possible, as it could be the difference between the lifetime of the gearbox and its failure. In some cases, a gearbox’s service factor can be as high as 1.4, which is sufficient for most industrial applications.
中国在可再生能源行业占据主导地位，拥有1000吉瓦的全球最大装机容量，每年发电量超过2000太瓦时。这些行业的增长预计将增加对齿轮箱的需求。例如，在中国，风能和水力发电是风力发电厂和太阳能发电厂的主要组成部分。装机容量的增长意味着这些行业对齿轮箱的需求将会增加。不适用于特定应用的齿轮箱将无法正常工作，这可能会对中国的产品生产造成不利影响。
A gearbox can be mounted in one of four different positions. The first three positions are concentric, parallel, or right angle, and the fourth position is shaft mount. A shaft mount gearbox is typically used in applications where the motor can’t be mounted via a foot. These positions are discussed in more detail below. Choosing the correct gearbox is essential in your business, but remember that a well-designed gearbox will help your bottom line.
变速箱的使用系数取决于负载类型。例如，高冲击载荷会导致齿轮齿或轴承过早失效。在这种情况下，需要更高的使用系数。而在其他情况下，专为承受高冲击载荷而设计的变速箱能够承受此类载荷而不降低其性能。此外，它还能降低变速箱的长期维护成本。

材料

在选择变速箱材料时，必须权衡设计的强度、耐用性和成本。本文将探讨不同类型的材料及其各自的应用和动力传输计算。多种合金可供选择，每种合金都有其自身的优势，包括更高的硬度和耐磨性。以下是一些齿轮中常用的合金。合金的优势在于其价格竞争力。由这些材料制成的齿轮通常比同类材料更坚固。
The carbon content of SPCC prevents the material from hardening like SS. However, thin sheets made from SPCC are often used for gears with lower strength. Because of the low carbon content, SPCC’s surface doesn’t harden as quickly as SS gears do, so soft nitriding is needed to provide hardness. However, if you want a gear that won’t rust, then you should consider SS or FCD.
除了汽车，变速箱在航空航天领域也发挥着重要作用。它们用于太空旅行和飞机发动机。在农业领域，它们用于灌溉、病虫害防治机械和耕作机械。它们也用于起重机、推土机和拖拉机等建筑设备。变速箱还应用于食品加工行业，包括输送系统、窑炉和包装机械。
变速箱齿轮的齿形对变速箱性能至关重要。齿轮啮合良好才能使变速箱发挥最佳性能并承受扭矩。齿轮齿就像微小的杠杆，有效的啮合可以减少应力和打滑。静态参数分析有助于确定整个齿轮运转周期内的啮合质量。这种方法通常是判断齿轮啮合是否良好的最准确方法。

The global gear market is divided into five key regions, namely, North America, Europe, Asia Pacific, and Latin America. Among these regions, Asia Pacific is expected to generate the largest GDP, owing to rapidly growing energy demand and investments in industrial infrastructure. This region is also home to some of the largest manufacturing bases, and its continuous building of new buildings and homes will support the industry’s growth. In terms of application, gearboxes are used in construction, agricultural machinery, and transportation.

全球健康危机和海运贸易的下滑对该行业产生了一定程度的不利影响。海运贸易的下滑阻碍了投资。预计到2020年4月，国际原油价格将跌破1美元，这将终结新资产的开发和开采。在这种情况下，全球变速箱市场将面临诸多挑战。然而，机遇也十分巨大。因此，得益于国内轻型车辆销量的增长，预计到2020年，工业变速箱市场规模将增长超过6100万吨。
变速箱的主轴，也称输出轴，以不同的速度旋转并将扭矩传递给汽车。输出轴带有花键，以便连接联轴器和齿轮。副轴和主轴由轴承支撑，轴承可以减少旋转部件的摩擦。变速箱的另一个重要部件是齿轮，齿轮的齿数各不相同。齿数决定了齿轮可以传递的扭矩大小。此外，齿轮可以在任何位置滑动。
