What is a worm gear reducer?
The worm gear reducer is used to change the output speed of the mechanical device. It consists of worm and helical gears mounted on the input side of the equipment. In some cases, this gear reduction system can be multi-stage, enabling extremely low output speeds. It has the advantages of low energy consumption and low vibration.
Hollow shaft worm gear reducer
Worm gear reducer is an effective device to reduce the speed of mechanical equipment. The use of hard steel or non-ferrous metals for the worm increases its efficiency. Worms made of hard steel generate more heat than worms made of mild steel. Different thermal expansion results in gaps between mating surfaces. Despite its many benefits, worm gear reducers are prone to oil leakage, which can be a problem for a number of reasons.
Hollow shaft worm gear reducers are available in different gear ratios and are compatible with many motor types. Some are available in dual-axis and single-axis configurations and can be mounted horizontally or vertically. They are also available in intermediate ratios, as well as four- and five-speed transmission types. They can also be connected with additional output shafts.
Another type of worm gear reducer is the multi-stage variety. This gear reducer has multiple stages, enabling it to reduce speed with extremely low output speeds. In addition to the large transmission ratio, the multi-stage gear reducer has low noise, low vibration and low energy consumption.
Worm gear reducers offer space-saving solutions as well as increased torque. Agknx Gearbox offers worm gear reducers that solve common deceleration problems. The company has also expanded its product range into the bathroom market. Compared with the standard gearbox, the worm gear reducer has the characteristics of lower price and better torque output.
hourglass worm gear
The hourglass type worm gear reducer has multi-tooth line contact and is widely used in heavy machinery. These gears are characterized by a high load-carrying capacity, but they are highly sensitive to misalignment and manufacturing errors. However, by employing point contact, these gears can be made more reliable and can withstand higher loads.
Another major advantage of the hourglass worm gear is its high load capacity. The tooth profile design of the gears has a high relative slip ratio, which improves efficiency and load capacity. In addition, the large angle between the sliding direction and the contact line provides a low coefficient of friction. The hourglass worm gear also features premium carburized steel and phosphor bronze castings for exceptional durability. In addition, the tooth profile is very precise, the operation is quiet, and the speed fluctuation is small.
Agknx worm gear reducers are designed to operate for up to ten hours per day with an even load. The design of this worm gear reducer stems from Sumitomo Heavy Industries' extensive experience in gear reducers. The smooth surface texture and precise tooth profile of the gears ensure that the gears can withstand high loads without damaging the lubricant film. In addition, Agknx worm shafts are specially designed to have the right stiffness.
Hourglass worm gear reducers are designed to maximize load capacity while minimizing energy consumption. Its fully meshed teeth reduce surface pressure on the worm gear teeth and increase load capacity.
Double throat worm gear
There are a few things to consider when choosing a dual-throat worm gear. First, the diameter of the root circle must match the circle pitch of the larger gear. This measurement is usually done by measuring the distance between adjacent teeth. Alternatively, the worm's normal module can be used. It is the value entered in the worm module dialog. In addition, the axial pitch of the worm should be equal to the pitch diameter of the circular pitch.
Double-throat worm gears are an excellent choice for heavy and heavy-duty applications. The design of this worm gear is ideal for heavy-duty applications as it provides a tighter connection between the worm and the gear. It is also more compact than other types of gear and is comparable to a fine-pitch lead screw.
The efficiency of a double-throat worm gear depends on the material of the gear and worm. Typically, gears are made of case-hardened steel, while worm gears are made of bronze or cast iron. In some cases, a combination of cast iron and bronze can be used.
The deflection of the worm shaft is also affected by the tooth parameters. Tooth height, pressure angle, and size factors all affect the deflection of the worm shaft. In addition, the number of worm threads is another important parameter that affects the deflection of the worm shaft.
Double-throat worm gears are commonly used in industrial applications where high drive reduction is required. The worm has a concave and internal tooth structure that can be adjusted to achieve various ratios. Worm gears and worm gear assemblies must be properly mounted on their shafts to prevent back drive.
Brass worm gear
The basic working principle of the brass worm gear reducer is the same as that of the traditional worm gear reducer. Its axial pitch must be equal to the circumferential pitch of the larger gear. The single-thread design advances one tooth per revolution, while the double-thread design advances two teeth. The threads on the worm are either left-handed or right-handed. The lead of a worm is the distance a point on the thread of the worm moves in one revolution. The lead angle is the angle tangent to the pitch of the cylinder and the axis of the worm.
Double-thread worm gear reducers are best for heavy loads. It provides the tightest connection between the worm and the gear. Assembly of the worm gear requires precise mounting. The keyway installation method involves drilling a square cut in the gear hole. This prevents the worm from rotating on the shaft and helps transmit torque. Then use the set screw to secure the gear to the hub.
The large fuel tank helps keep the worm gear clean and reduces heat. It also provides lubrication for extended life. Worm gear reducers with oil reservoirs provide a lubricated environment and low-friction surfaces. Additionally, it offers multi-position installation flexibility. Additionally, its housing is cross-milled for precise alignment. It also features internal baffles for leak-free ventilation.
I260 series worm gear reducers are one-piece iron casings with solid or hollow output shafts and tapered roller bearings. This gear reducer is designed for low to medium-horsepower applications. This gear reducer is a cost-effective option with low initial cost, the high gear ratio, and high torque in a compact package. Also, it is more shock resistant than other gear reducers.
Brass worm gear
Brass worm gear reducer is a reduction gear. This type of gear can provide a lot of reduction in a small package. This type of gear reducer also has the ability to generate high torque. However, it is important to understand that this gear reducer has thermal limitations, which reduce its efficiency. The choice of lubricant for this gear reducer is very flexible. However, being a yellow metal, it is important to remember that the lubricant must be non-reactive.
Worm gears are used in many consumer and industrial applications and have high reduction ratios. These gears are produced in various configurations and sizes. Worm gears are similar to spur gears but have non-parallel shafts. Worm gears are also suitable for applications requiring low output speed but high torque.
Worm gears have some distinct advantages over other gears. First, unlike standard gears, the worm rotates in a worm-like motion. This mechanism prevents reverse movement. This is because the lead angle of the worm gear is small. Additionally, the worms self-lock, helping to prevent reversal. However, this mechanism is not entirely reliable. Worm gears can be found in elevators, fishing reels, sprockets, and automotive power steering.
Another advantage of worm gears is that they are easy to manufacture. The rationale behind this design is to have two mutually perpendicular axes. Then, two or more threads are added to the worm gear. The common tangent between these two shafts intersects the pitch line of the worm gear shaft. This is the basis of transfer speed.
