如何为您的任务选择合适的蜗杆轴和设备

You will discover about axial pitch PX and tooth parameters for a Worm Shaft twenty and Gear 22. Comprehensive info on these two elements will help you choose a ideal Worm Shaft. Read through on to discover a lot more….and get your palms on the most sophisticated gearbox ever designed! Below are some ideas for picking a Worm Shaft and Gear for your task!…and a handful of items to keep in mind.

设备 22

The tooth profile of Equipment 22 on Worm Shaft twenty differs from that of a conventional gear. This is simply because the teeth of Gear 22 are concave, permitting for greater conversation with the threads of the worm shaft twenty. The worm’s lead angle triggers the worm to self-lock, stopping reverse movement. However, this self-locking mechanism is not entirely trusted. Worm gears are used in many industrial purposes, from elevators to fishing reels and automotive electricity steering.
新齿轮安装在油封固定的轴上。要安装新齿轮，首先需要拆下旧齿轮。然后，拧下将齿轮固定在轴上的两个螺栓。接下来，必须从输出轴上拆下轴承座。蜗轮蜗杆拆下后，拧下挡圈。之后，安装轴承锥体和轴垫片。确保轴已适当拧紧，但不要过度拧紧螺塞。
为防止过早失效，请使用适用于蜗轮蜗杆设备的正确润滑剂。蜗轮蜗杆的滑动需要粘度较高的润滑油。在三分之二的应用场景中，润滑剂不足。如果蜗轮蜗杆负载较轻，低粘度润滑油可能就足够了。否则，则需要使用粘度较高的润滑油来保持蜗轮蜗杆的良好状态。
One more option is to range the amount of teeth about the equipment 22 to lessen the output shaft’s pace. This can be completed by environment a certain ratio (for instance, five or 10 occasions the motor’s speed) and modifying the worm’s dedendum accordingly. This procedure will lessen the output shaft’s pace to the wanted amount. The worm’s dedendum must be adapted to the desired axial pitch.

蜗杆二十

选择蜗轮蜗杆传动装置时，应考虑以下因素。这些装置具有整体性能高、噪音低、耐用、耐高温和使用寿命长等优点。蜗轮蜗杆广泛应用于各个行业，并具有诸多优势。以下仅列举部分优点。请继续阅读以了解更多详情。蜗轮蜗杆的维护可能较为复杂，但只要维护得当，它们就能非常可靠。
蜗杆轴配置为由壳体 24 支撑。壳体 24 的尺寸由蜗杆轴 20 和输出轴 16 的中心距决定。如果配置不当，蜗杆轴和设备 22 可能会相互接触或干扰。因此，正确的装配至关重要。但是，如果蜗杆轴 20 安装不正确，则该组件将无法正常工作。
另一个需要考虑的关键因素是蜗杆的材质。有些蜗轮蜗杆使用黄铜轮，这可能会导致蜗杆腐蚀。此外，含硫磷的极压齿轮油会在黄铜轮上发生反应。这些因素都会导致接触面积显著下降。为了避免这些问题，蜗轮蜗杆应该使用优质润滑油。同时，还需要选择高粘度、低摩擦系数的润滑油。
减速器可由多种不同的蜗杆组成，每种减速器所需的减速比也各不相同。在这种情况下，减速器制造商可以提供不同螺纹设计的蜗杆。不同的螺纹设计对应不同的减速比。无论减速比如何，每根蜗杆都是用带有所需螺纹的毛坯加工而成。因此，找到符合您需求的蜗杆并不难。

Gear 22’s axial pitch PX

蜗轮蜗杆传动装置的轴向节距是通过标称轴心长度和齿顶高（一个常数）计算得出的。轴心长度是指从齿轮中心到蜗轮的距离。蜗轮节距也称为蜗杆节距。同样，在计算齿轮22的轴向节距PX时，也需要考虑尺寸和节圆直径。
The axial pitch, or direct angle, of a worm gear determines how powerful it is. The higher the guide angle, the less effective the gear. Lead angles are straight related to the worm gear’s load capability. In distinct, the angle of the lead is proportional to the duration of the tension spot on the worm wheel tooth. A worm gear’s load potential is straight proportional to the volume of root bending tension released by cantilever action. A worm with a guide angle of g is nearly equivalent to a helical equipment with a helix angle of ninety deg.
本发明描述了一种改进的蜗杆轴制造技术。该方法包括针对每个减速比和轴体尺寸确定所需的轴向螺距 PX。轴向螺距的确定方法是制造一种螺纹与所需齿轮比相对应的蜗杆轴。齿轮是由齿和蜗杆组成的旋转组件。
In addition to the axial pitch, a worm gear’s shaft can also be created from diverse materials. The content used for the gear’s worms is an important thought in its selection. Worm gears are normally produced of metal, which is stronger and corrosion-resistant than other materials. They also demand lubrication and may possibly have ground tooth to decrease friction. In addition, worm gears are often quieter than other gears.

Gear 22’s tooth parameters

A review of Gear 22’s tooth parameters uncovered that the worm shaft’s deflection is dependent on numerous aspects. The parameters of the worm equipment were diverse to account for the worm equipment size, force angle, and size aspect. In addition, the quantity of worm threads was changed. These parameters are different based mostly on the ISO/TS 14521 reference gear. This examine validates the designed numerical calculation model utilizing experimental final results from Lutz and FEM calculations of worm equipment shafts.
利用卢茨检验的最终结果，我们可以采用ISO/TS 14521和DIN 3996的计算方法得到蜗杆轴的挠度。根据AGMA 6022和DIN 3996中提供的公式计算蜗杆轴的弯曲直径，与检验结果吻合良好。然而，使用蜗杆根部直径计算蜗杆轴时，其弯曲直径的计算采用了不同的参数。
通过有限元分析（FEM）计算蜗杆轴的弯曲刚度。利用FEM仿真，可以根据蜗杆轴的齿轮参数计算其挠度。由于蜗杆齿轮的刚度已确定，因此该挠度可视为完整齿轮箱技术的一部分。最后，主要基于这项研究，提出了一种修正方法。
For an perfect worm gear, the number of thread starts off is proportional to the dimensions of the worm. The worm’s diameter and toothing issue are calculated from Equation 9, which is a method for the worm gear’s root inertia. The distance amongst the major axes and the worm shaft is determined by Equation fourteen.

Gear 22’s deflection

为了研究齿轮参数对蜗杆轴挠度的影响，我们采用了有限元分析法。考虑的参数包括齿顶、力角、尺寸元素和蜗杆螺纹数。这些参数对蜗杆轴的弯曲均有不同的影响。表1列出了参考齿轮（齿轮22）和不同齿轮设计的参数模型。蜗杆的尺寸和螺纹数决定了蜗杆轴的挠度。
ISO/TS 14521 的计算策略基于 Lutz 检验装置的边界问题。该方法采用有限元法计算蜗杆轴的挠度。实验计算得到的轴与仿真结果进行了比较。通过对比实验结果和修正部分，验证了计算挠度与测量挠度的一致性。
The FEM evaluation signifies the influence of tooth parameters on worm shaft bending. Equipment 22’s deflection on Worm Shaft can be defined by the ratio of tooth power to mass. The ratio of worm tooth force to mass determines the torque. The ratio between the two parameters is the rotational pace. The ratio of worm gear tooth forces to worm shaft mass decides the deflection of worm gears. The deflection of a worm gear has an influence on worm shaft bending ability, performance, and NVH. The ongoing development of power density has been accomplished by means of advancements in bronze resources, lubricants, and manufacturing quality.
