BWD XWD Series Cycloidal Gearbox Single Stage Horizontal Foot-mounted with Motor

Overview of Cycloidal Gearbox

1. High speed ratio and efficiencyThe reduction ratio of single-stage transmission can reach 1:87, and the efficiency can reach more than 90%. If multi speed drive is used, the reduction ratio is greater.
2. Compact structure and small volumeThe principle of planetary transmission is adopted. The input and output shafts are located in the same axis, and the structure is compact.
3. Stable operation and low noiseCycloidal pinwheel has many meshing teeth, large overlap coefficient, stable mechanical parts, and vibration and noise are limited to the minimum range.
4. Reliable operation and long service lifeAs the main components are made of bearing steel after quenching treatment (HRC58-62), they have high strength. At the same time, the transmission contact of parts adapts to rolling friction, so it is durable and has a long service life.
5. Strong overload capacity, impact resistance and small inertia moment.It is used for frequent startup and positive and negative rotation.

Features of Cycloidal Gearbox

•  High speed ratio and high efficiency single-stage transmission can achieve a reduction ratio of 1:87, and the efficiency is above 90%. If multistage transmission is adopted, the reduction ratio is greater.
• Compact Due to the principle of planetary transmission, the input shaft and output shaft are located on the same axis, making the model as small as possible.
• Stable operation and low noise cycloidal needle teeth have a large number of meshing teeth, a large overlap coefficient and a mechanism to balance parts, so as to minimize vibration and buzzing.
• Reliable use and long service life Because the main parts are made of high carbon chromium steel, which have obtained high strength through quenching treatment (HRC58~62), and some transmission contacts use rolling friction, they have a long durability and service life.

The cycloidal pin gear box adopts the principle of cycloidal pin gear engagement and planetary transmission, so it is also called the planetary cycloidal gear box. Planetary cycloid gear boxes can be widely used in petroleum, environmental protection, chemical industry, cement, transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation and other industries as transmission or gear boxes. Its unique smooth structure can replace ordinary cylindrical gear box and worm gear box in many cases. Therefore, planetary cycloidal gear boxes are widely used in various industries and fields, and are widely welcomed by users.Service conditions:

1.  It is allowed to use cycloidal pin gear box in continuous working system, whileBoth forward and reverse directions are allowed.
2. The rated speed of the input shaft is 1500 rpm. When the input power is greater than 18.5kW, a 6-pole motor with 960 rpm is recommended.
3. The working position of the cycloidal gear box installed horizontally is horizontal. MaximumThe horizontal inclination during installation is usually less than 15 °. Other measures should be taken ensure adequate lubrication and prevent oil leakage when exceeding 15 °.
4. The output shaft of cycloidal gear box cannot bear large axial and radial forces. in additionWhen there are large axial and radial forces, measures must be taken.

Lubrication of Cycloidal Gearbox

1. The horizontal cycloidal reducer adopts oil pool lubrication under normal conditions, and the oil level can be kept in the middle of the oil window. When the working conditions are bad and the ambient temperature is high, the circular lubrication can be used.
2. The cycloidal pin gear reducer is generally lubricated with 40 # or 50 # machine oil at normal temperature. In order to improve the performance of the reducer and prolong the service life of the cycloidal pin gear reducer, 70 # or 90 # extreme pressure gear oil is recommended. The lubricating oil can also be re considered when working at high and low temperatures.
3. When the planetary cycloidal pin gear reducer is installed vertically, the oil pump shall be strictly prevented from cutting off oil to avoid damage to the reducer components.
4. To refuel, unscrew the vent cap on the upper part of the engine seat. When draining the oil, unscrew the oil drain plug at the lower part of the engine seat to drain the dirty oil. There is no lubricating oil inside the reducer when it leaves the factory.
5. The oil shall be replaced after the first refueling operation for 100 hours. (The internal dirty oil shall be flushed clean) Then the oil shall be continuously operated. The oil shall be replaced every half a year (8 hour working system). If the working conditions are bad, the oil change time can be appropriately shortened. Practice has proved that regular cleaning and oil change of the reducer (such as 3-6 months) play an important role in extending the service life of the reducer. The lubricating oil shall be replenished frequently during use.
6. The ex factory reducer has been greased and replaced every six months. Aluminum disulfide - 2 # or 2L-2 # lithium base lubricating grease shall be used.

What are the Advantages of Cycloidal Gear?

Applications with particularly high accuracy - whether in plant engineering, robotics, machine tool manufacturing or medical technology - require the design of durable precision gears. There are two types of gears available for this type of application: planetary gears and cycloidal gears. Although the range of use of these two gear types overlaps, cycloidal gears can replace planetary gears in many applications.If the characteristics such as backlash and positioning accuracy are important, cycloidal gears can provide better performance in all aspects. Their design is stronger than planetary gears, which means they have a longer life. In addition, the increase of the backlash of cycloidal gears is very small over a long period of time, which is a significant advantage over normal planetary gears, which often increase the backlash during their service life.Cycloidal gears can achieve a reduction ratio of more than 30:1 to 300:1, without additional front stage, such as the front stage required by standard planetary gears. Because of its design, cycloidal gears are more rigid, compact (about 50% shorter) and lighter than multi-stage planetary gears. In addition, they provide 500% overload protection.Advantages of cycloidal gear over planetary gear:

• Stronger structure
• Longer service life
• Almost no recoil for life
• Higher rigidity
• More compact design
• Lower weight
• Higher overload protection

No other prephasesCycloidal gear has these characteristics because of its special design principle. Because of the cycloidal design, the gear does not need teeth at the output stage and is not affected by the shear force. This makes them extremely efficient, accurate and robust.Power is transmitted through typical rollers and cams of cycloidal gears, ensuring high efficiency, long service life and extremely low backlash of gears. Almost complete contact and uniform force distribution in the cycloidal pin structure achieve high bearing capacity. The two-stage deceleration principle minimizes vibration and mass inertia, while allowing higher deceleration ratios.
