In this article, we are going to discuss how to calculate the deflection of a worm gear’s worm shaft. We will also examine the characteristics of a worm gear, like its tooth forces. And we will cover the critical traits of a worm equipment. Go through on to understand far more! Here are some items to consider prior to getting a worm equipment. We hope you appreciate finding out! Right after studying this write-up, you may be nicely-equipped to choose a worm gear to match your demands.
计算的主要目标是确定蜗杆的挠度。蜗杆用于驱动齿轮和机械装置。这种传动方式采用蜗杆。蜗杆直径和齿数会逐步输入到计算中。然后,屏幕上会显示一个包含相应计算结果的表格。完成表格计算后,即可进行主要计算。您还可以修改力参数。
采用有限元方法 (FEM) 计算蜗杆轴的最大挠度。该模型包含多个参数,包括尺寸测量和边界条件。将这些仿真结果与相应的解析值进行对比,以确定最佳挠度。最终生成一个表格,显示蜗杆轴的最大挠度。表格可在下方下载。您还可以找到更多关于各种挠度公式及其应用的信息。
DIN EN 10084 所采用的计算方法基于 16MnCr5 硬质合金螺杆。因此,您可以使用 DIN EN 10084 (CuSn12Ni2-C-GZ) 和 DIN EN 1982 (CuAl10Fe5Ne5-C-GZ)。然后,您可以手动输入螺杆端面宽度,也可以使用自动建议选项。
Widespread strategies for the calculation of worm shaft deflection offer a very good approximation of deflection but do not account for geometric modifications on the worm. Even though Norgauer’s 2021 strategy addresses these problems, it fails to account for the helical winding of the worm tooth and overestimates the stiffening result of gearing. More sophisticated ways are essential for the effective style of slim worm shafts.
与其他类型的机械装置相比,蜗轮蜗杆传动装置的噪音和振动较小。然而,由于蜗轮较软,磨损量通常较大,因此蜗轮蜗杆传动装置的性能往往受到限制。蜗杆轴的挠度是影响噪音和磨损的重要因素。蜗轮蜗杆传动装置挠度的计算方法在 ISO/TR 14521、DIN 3996 和 AGMA 6022 标准中均有规定。
蜗轮蜗杆传动装置可以设计成具有精确传动比的传动方式。计算方法是将传动比分配到变速箱的多个齿轮级上。电力传输的输入参数以及蜗杆/齿轮的材料都会影响传动性能。为了获得更高的效率,蜗杆/齿轮的材料必须与将要遇到的情况相匹配。蜗轮蜗杆传动装置可以是一种自锁式传动装置。
The worm gearbox contains several equipment elements. The main contributors to the overall electrical power reduction are the axial loads and bearing losses on the worm shaft. That’s why, different bearing configurations are studied. One particular kind consists of finding/non-locating bearing preparations. The other is tapered roller bearings. The worm equipment drives are regarded when locating versus non-locating bearings. The investigation of worm gear drives is also an investigation of the X-arrangement and 4-point speak to bearings.
蜗轮蜗杆设备的弯曲刚度取决于齿力。随着能量密度的提高,齿力也会增大,但这同时也会导致蜗杆轴挠度增大。由此产生的挠度会影响效率、负载能力和噪声、振动与声振粗糙度(NVH)性能。青铜资源、润滑剂和制造工艺的不断进步,使得蜗轮蜗杆设备制造商能够生产出能量密度更高的产品。
标准化的计算策略考虑了蜗杆轴上齿轮的支撑作用。然而,悬臂式蜗轮蜗杆并未纳入计算。此外,在蜗杆装置之后设计轴时,才考虑齿轮啮合面积。同样,齿根直径被等效为弯曲直径,但这忽略了蜗杆齿轮的支撑作用。
本文提出了一种通用公式来估算STE对振动激励的贡献。该公式适用于任何具有啮合模式的设备。建议工程师测试不同的啮合策略以获得更精确的结果。一种分析齿轮啮合面的方法是使用有限元应力和网格子程序。该软件可以评估动态质量作用下的齿轮弯曲应力。
刷牙和润滑对弯曲刚度的影响可以通过增加蜗杆副的应力角来体现。这可以降低蜗杆机构中的齿弯曲应力。另一种方法是采用负载齿接触分析(CCTA)。该方法也用于评估不匹配的ZC1蜗杆行程。该方法获得的结果已广泛应用于各种类型的齿轮传动装置。
In this research, we identified that the ring gear’s bending stiffness is highly affected by the tooth. The chamfered root of the ring gear is bigger than the slot width. Thus, the ring gear’s bending stiffness differs with its tooth width, which raises with the ring wall thickness. In addition, a variation in the ring wall thickness of the worm gear triggers a greater deviation from the design and style specification.
为了了解齿形对蜗轮弯曲刚度的影响,齿根形状至关重要。渐开线齿容易受到弯曲应力的影响,在极端情况下可能发生断裂。通过齿根形状和弯曲刚度分析,可以有效控制断裂。优化末级齿轮的齿根形状能够最大限度地降低渐开线齿的弯曲应力。
本文利用CZPT螺旋锥齿轮试验台,研究了齿力对蜗轮蜗杆机构弯曲刚度的影响。试验中,在螺旋锥齿轮的多个齿面上安装了压力传感器,并在从静止到14400 RPM的转速范围内进行了测试。测试功率最高可达540 kW。所得结果与三维有限元模型的分析结果进行了比较。
Worm gears are exclusive varieties of gears. They characteristic a assortment of attributes and apps. This report will take a look at the traits and rewards of worm gears. Then, we’ll look at the typical apps of worm gears. Let us just take a search! Before we dive in to worm gears, let us assessment their capabilities. Hopefully, you will see how versatile these gears are.
蜗轮蜗杆传动装置只需少量工作即可实现极高的减速比。通过增加蜗轮的圆周长度,蜗杆可以显著提高扭矩并降低速度。传统的齿轮传动装置需要多次减速才能达到相同的减速比。蜗轮蜗杆传动装置的传动元件少得多,因此故障点也少得多。即便如此,它们也无法反转电流方向。这是因为蜗杆和蜗轮之间的摩擦力使得蜗杆反向运动极其困难。
Worm gears are extensively utilised in elevators, hoists, and lifts. They are specifically valuable in programs exactly where stopping pace is critical. They can be integrated with smaller brakes to ensure safety, but shouldn’t be relied upon as a main braking system. Normally, they are self-locking, so they are a very good decision for a lot of apps. They also have a lot of positive aspects, which includes enhanced performance and protection.
蜗轮蜗杆用于实现特定的减速比。它们通常安装在电机的输入轴和输出轴以及负载之间。这两个轴通常以一定角度布置,以确保合适的对准。蜗轮蜗杆的中心距是其本体尺寸的一部分。齿轮和蜗杆的中心距决定了轴向节距。例如,如果齿轮组沿径向布置,则必须减小其外径。
Worm gears’ sliding speak to decreases efficiency. But it also ensures quiet procedure. The sliding motion restrictions the performance of worm gears to 30% to fifty%. A handful of methods are released herein to lessen friction and to produce good entrance and exit gaps. You will soon see why they are such a versatile option for your demands! So, if you are thinking about acquiring a worm gear, make confident you read this article to find out a lot more about its characteristics!
图 19 和图 20 描述了一种蜗轮蜗杆传动装置的实施例。该技术的另一种实施例采用单个电机和单个蜗杆 153。蜗杆 153 带动一个齿轮转动,该齿轮驱动机械臂 152。机械臂 152 反过来使透镜/反射镜组件 10 改变仰角。然后,电机控制单元 114 跟踪透镜/反射镜组件 10 相对于参考位置的仰角。
蜗轮和蜗杆均由钢制成。然而,黄铜蜗杆和蜗轮则由黄铜制成,黄铜是一种黄钢。它们的润滑剂选择范围更广,但由于其黄钢的特性,添加剂的使用受到限制。塑料-金属蜗轮通常用于轻载荷应用。所使用的润滑剂取决于塑料的种类,因为许多种类的塑料会对普通润滑剂中的碳氢化合物产生反应。因此,需要使用非反应性润滑剂。
