如何为您的项目选择合适的蜗杆轴和设备

You will understand about axial pitch PX and tooth parameters for a Worm Shaft 20 and Equipment 22. Detailed data on these two factors will help you choose a ideal Worm Shaft. Read through on to find out a lot more….and get your arms on the most innovative gearbox ever developed! Right here are some tips for choosing a Worm Shaft and Gear for your venture!…and a couple of issues to hold in head.

22号齿轮

The tooth profile of Gear 22 on Worm Shaft 20 differs from that of a conventional equipment. This is due to the fact the enamel of Equipment 22 are concave, enabling for better conversation with the threads of the worm shaft twenty. The worm’s guide angle leads to the worm to self-lock, protecting against reverse motion. Even so, this self-locking mechanism is not totally dependable. Worm gears are used in many industrial purposes, from elevators to fishing reels and automotive energy steering.
新齿轮安装在由油封固定的轴上。要安装新齿轮，首先需要拆下旧齿轮。接下来，需要拧下将齿轮固定在轴上的两个螺栓。然后，从输出轴上拆下轴承座。蜗轮拆下后，需要拧下挡圈。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，应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高粘度润滑油。在三分之二的应用中，润滑剂不足。如果蜗杆负载较轻，低粘度润滑油可能就足够了。否则，必须使用高粘度润滑油才能确保蜗轮蜗杆处于良好状态。
Another selection is to vary the quantity of teeth about the equipment 22 to lessen the output shaft’s speed. This can be done by environment a certain ratio (for instance, five or ten instances the motor’s velocity) and modifying the worm’s dedendum appropriately. This procedure will reduce the output shaft’s velocity to the wanted level. The worm’s dedendum need to be adapted to the wanted axial pitch.

蜗杆轴 20

选择蜗轮蜗杆传动装置时，应考虑以下几个方面。这些装置效率高、噪音低，坚固耐用、运行温度低且使用寿命长。蜗轮蜗杆广泛应用于众多行业，并具有诸多优势。以下仅列举部分优点。更多信息，请继续阅读。蜗轮蜗杆的维护可能较为复杂，但只要维护得当，就能非常可靠。
蜗杆轴配置为由框架 24 支撑。框架 24 的尺寸由蜗杆轴 20 与输出轴 16 之间的中心距决定。如果配置不当，蜗杆轴和齿轮 22 可能相互接触或干涉。因此，正确的装配至关重要。然而，如果蜗杆轴 20 安装不当，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材质。有些蜗轮蜗杆采用黄铜轮，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减小。为了避免这些问题，蜗轮蜗杆需要使用优质润滑剂。同时，还应选择粘度高、摩擦系数低的润滑剂。
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具有不同螺纹规格的蜗杆。不同的螺纹规格对应不同的减速比。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，找到一款符合您需求的蜗杆并不难。

Equipment 22’s axial pitch PX

蜗轮蜗杆机构的轴向螺距是通过使用标称轴心距和齿顶元素（一个连续的参数）来计算的。轴心距是指从机构中心到蜗轮的距离。蜗轮螺距也称为蜗杆螺距。在计算机构 22 的轴向螺距 PX 时，需要考虑尺寸和节圆直径。
The axial pitch, or guide angle, of a worm gear establishes how effective it is. The greater the direct angle, the considerably less productive the equipment. Direct angles are immediately related to the worm gear’s load capability. In particular, the angle of the lead is proportional to the duration of the anxiety location on the worm wheel teeth. A worm gear’s load potential is immediately proportional to the sum of root bending anxiety released by cantilever action. A worm with a lead angle of g is virtually equivalent to a helical gear with a helix angle of ninety deg.
本发明描述了一种改进的蜗杆轴制造策略。该方法包括针对每个减速比和机架尺寸确定所需的轴向螺距 PX。轴向螺距的确定是通过制造螺纹与所需齿轮比相对应的蜗杆轴来实现的。该设备是由齿轮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 supplies. The materials utilized for the gear’s worms is an essential thing to consider in its choice. Worm gears are normally produced of steel, which is stronger and corrosion-resistant than other materials. They also demand lubrication and may have ground tooth to lessen friction. In addition, worm gears are typically quieter than other gears.

Equipment 22’s tooth parameters

A review of Gear 22’s tooth parameters uncovered that the worm shaft’s deflection depends on various elements. The parameters of the worm gear have been different to account for the worm gear dimensions, pressure angle, and dimension issue. In addition, the number of worm threads was altered. These parameters are varied based mostly on the ISO/TS 14521 reference gear. This examine validates the designed numerical calculation design employing experimental final results from Lutz and FEM calculations of worm gear shafts.
利用卢茨试验的最终结果，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中给出的公式计算蜗杆轴的弯曲直径与试验最终结果具有良好的相关性。然而，利用蜗杆根部直径计算蜗杆轴时，需要使用不同的参数来估算等效弯曲直径。
本文采用有限元分析法（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。对于综合齿轮箱技术而言，该挠度可视为蜗杆齿轮刚度的指标。最终，基于这项研究，推导出了一个修正系数。
For an perfect worm gear, the number of thread starts off is proportional to the dimension of the worm. The worm’s diameter and toothing issue are calculated from Equation 9, which is a system for the worm gear’s root inertia. The length amongst the major axes and the worm shaft is identified by Equation 14.

Gear 22’s deflection

为了研究齿轮参数对蜗杆轴挠度的影响，我们采用了有限元方法。考虑的参数包括齿高、力角、尺寸比例和蜗杆螺纹数。每个参数对蜗杆轴的弯曲都有不同的影响。表1列出了参考设备（齿轮22）和不同齿轮产品的参数组合。蜗杆设备的尺寸和螺纹数决定了蜗杆轴的挠度。
ISO/TS 14521 的计算方法取决于 Lutz 校核装置的边界条件。该方法采用有限因子法计算蜗杆轴的挠度。实验测量的轴与仿真结果进行了比较。通过比较试验最终结果和修正值，确认计算挠度与测量挠度相当。
The FEM examination signifies the influence of tooth parameters on worm shaft bending. Equipment 22’s deflection on Worm Shaft can be explained by the ratio of tooth power to mass. The ratio of worm tooth drive to mass decides the torque. The ratio in between the two parameters is the rotational pace. The ratio of worm gear tooth forces to worm shaft mass determines the deflection of worm gears. The deflection of a worm equipment has an influence on worm shaft bending capability, efficiency, and NVH. The steady improvement of electrical power density has been reached by means of improvements in bronze materials, lubricants, and manufacturing high quality.
