蜗轮蜗杆和齿轮箱

如果您正在使用变速箱，您可能想知道哪种蜗杆轴最适合您的应用。有很多因素需要考虑，例如凹面形状、螺纹数量和润滑方式。本文将解释每一个问题，并帮助您为您的变速箱选择合适的蜗杆轴。市场上有很多选择，所以不要犹豫多方比较。如果您是变速箱领域的新手，请继续阅读，了解更多关于这种常见变速箱的信息。

The geometry of a worm gear varies considerably depending on its manufacturer and its intended use. Early worms had a standard profile that resembled a screw thread and could be chased on a lathe. Afterwards, instruments with a straight sided g-angle had been developed to create threads that were parallel to the worm’s axis. Grinding was also produced to improve the finish of worm threads and decrease distortions that arise with hardening.
To decide on a worm with the appropriate geometry, the diameter of the worm equipment have to be in the very same unit as the worm’s shaft. After the basic profile of the worm gear is decided, the worm equipment tooth can be specified. The calculation also entails an angle for the worm shaft to avoid it from overheating. The angle of the worm shaft must be as close to the vertical axis as achievable.
另一方面，双包络蜗轮蜗杆蜗杆周围没有喉部。它们是螺旋齿轮，蜗杆轴是直的。由于蜗杆的齿彼此接触，因此会产生相当大的摩擦。与双包络蜗轮蜗杆相比，无喉蜗轮蜗杆结构更紧凑，能够承受更小的载荷。它们也更容易制造。
不同厂家生产的蜗轮蜗杆各有优势。例如，蜗轮蜗杆是提高扭矩最有效的方法之一，但低质量的部件（如青铜）润滑困难。蜗轮蜗杆的故障率也较低，因为它们在设计方法上允许较大的灵活性。尽管两种标准之间存在差异，但蜗轮蜗杆系统的整体功能是相同的。
锥形蜗杆是另一种类型。这种技术方案将直轴蜗杆与凹弧相结合。凹弧也是一种实用性很强的设计。这种形状的蜗杆可以同时与多个部件接触，这意味着它们可以在不产生异常磨损的情况下减小较大的直径。此外，它也是一种成本相对较低的设计。

线迹图案

A great worm gear needs a best thread sample. There are a few important parameters that decide how excellent a thread sample is. Firstly, the threading sample need to be ACME-threaded. If this is not attainable, the thread have to be created with straight sides. Then, the linear pitch of the “worm” have to be the same as the round pitch of the corresponding worm wheel. In straightforward terms, this means the pitch of the “worm” is the very same as the round pitch of the worm wheel. A swift-change gearbox is typically utilised with this variety of worm equipment. Alternatively, lead-screw modify gears are utilised instead of a quick-alter equipment box. The pitch of a worm gear equals the helix angle of a screw.
A worm gear’s axial pitch have to match the round pitch of a gear with a greater axial pitch. The round pitch is the distance between the details of enamel on the worm, although the axial pitch is the length in between the worm’s enamel. One more aspect is the worm’s lead angle. The angle amongst the pitch cylinder and worm shaft is called its lead angle, and the larger the lead angle, the greater the effectiveness of a equipment.
蜗轮蜗杆的齿形几何形状可能因制造商和用途而异。早期的蜗轮蜗杆，其螺纹类似于螺丝上的螺纹，可以用车床轻松加工。后来，磨削工艺提高了蜗轮蜗杆螺纹的表面光洁度，并最大限度地减少了硬化造成的变形。因此，如今大多数蜗轮蜗杆的螺纹规格都与其尺寸相匹配。在选择蜗轮蜗杆时，务必在购买前确认螺纹数量。
A worm gear’s threading is vital in its procedure. Worm tooth are generally cylindrical, and are organized in a sample related to screw or nut threads. Worm tooth are frequently formed on an axis of perpendicular in comparison to their parallel counterparts. Simply because of this, they have greater torque than their spur equipment counterparts. Furthermore, the gearing has a minimal output velocity and large torque.

线程数

不同类型的蜗轮蜗杆机构在其行星齿轮上使用不同数量的螺纹。单螺纹蜗轮蜗杆机构不能与双螺纹蜗杆一起使用。单螺纹蜗轮蜗杆机构必须与单螺纹蜗杆一起使用。单螺纹蜗杆比双螺纹蜗杆减速效率更高。
The variety of threads on a worm’s shaft is a ratio that compares the pitch diameter and number of tooth. In general, worms have 1,2,4 threads, but some have three, five, or 6. Counting thread starts off can support you establish the quantity of threads on a worm. A single-threaded worm has much less threads than a a number of-threaded worm, but a multi-threaded worm will have more threads than a mono-threaded planetary equipment.
To evaluate the quantity of threads on a worm shaft, a little fixture with two ground faces is utilised. The worm need to be removed from its housing so that the completed thread region can be inspected. Following pinpointing the quantity of threads, simple measurements of the worm’s outdoors diameter and thread depth are taken. Once the worm has been accounted for, a solid of the tooth place is produced employing epoxy material. The casting is moulded between the two tooth flanks. The V-block fixture rests from the outside diameter of the worm.
The circular pitch of a worm and its axial pitch should match the round pitch of a greater equipment. The axial pitch of a worm is the distance amongst the factors of the enamel on a worm’s pitch diameter. The lead of a thread is the length a thread travels in a single revolution. The direct angle is the tangent to the helix of a thread on a cylinder.
The worm gear’s velocity transmission ratio is based on the amount of threads. A worm equipment with a substantial ratio can be easily decreased in a single step by making use of a set of worm gears. Nonetheless, a multi-thread worm will have more than two threads. The worm gear is also much more successful than one-threaded gears. And a worm equipment with a large ratio will permit the motor to be utilized in a variety of applications.

润滑

由于蜗轮蜗杆传动装置的摩擦力大且滑动接触力高，其润滑要求尤为苛刻。幸运的是，润滑剂的选择多种多样，例如复合油。复合油是一种矿物油基润滑剂，其配方中添加了10%或以上的脂肪酸、防锈剂、抗氧化剂和其他添加剂。这种混合配方最终能够提高润滑性、降低摩擦并减少滑动磨损。
When choosing a lubricant for a worm shaft, make sure the product’s viscosity is right for the kind of gearing employed. A low viscosity will make the gearbox challenging to actuate and rotate. Worm gears also endure a increased sliding movement than rolling movement, so grease have to be ready to migrate evenly throughout the gearbox. Repeated sliding motions will drive the grease away from the contact zone.
另一个需要考虑的因素是齿轮的齿隙。蜗轮蜗杆的传动比通常很高，一般为300:1。这对于电力系统来说至关重要，但同时也效率低下。蜗轮蜗杆在滑动过程中会产生热量，因此使用优质润滑油至关重要。这种润滑油可以降低温度并确保最佳性能。以下提示将帮助您为蜗轮蜗杆选择合适的润滑油。
In reduced-velocity apps, a grease lubricant may be adequate. In greater-speed purposes, it is best to use a artificial lubricant to avert premature failure and tooth put on. In each circumstances, lubricant decision depends on the tangential and rotational pace. It is crucial to adhere to manufacturer’s tips with regards to the option of lubricant. But keep in mind that lubricant choice is not an straightforward activity.
