product description:
The X/B cycloidal pinwheel reducer is a kind of machinery that achieves deceleration by the meshing of cycloidal pin teeth according to the principle of planetary transmission with less tooth difference.The machine is divided into horizontal, vertical, double-shaft and direct-connected assembly methods. It is the first-choice equipment for metallurgy, mining, construction, chemical, textile, light industry and other industries.


Structure and principle:
Cycloidal pin gear reducer is a novel transmission device that applies the principle of planetary transmission and adopts the meshing of cycloidal pin teeth.The entire transmission device of the cycloidal pinwheel reducer can be divided into three parts: input part, deceleration part, and output part.A double eccentric sleeve with a displacement of 180° is installed on the input shaft. Two roller bearings called swing arms are installed on the eccentric sleeve to form an H mechanism. The center holes of the two cycloids are the upper swing arm bearings of the eccentric sleeve In order to reduce the friction, in a reducer with a small speed ratio, the cycloidal gear meshes with a set of circularly arranged needle teeth on the needle gear to form an internal meshing reduction mechanism with a tooth difference of one tooth. , Needle tooth sleeve is attached to the needle tooth).
When the input shaft rotates one circle with the eccentric sleeve, due to the characteristics of the upper tooth profile curve of the cycloidal wheel and the limitation of the needle gear on the needle gear, the motion of the cycloidal wheel becomes a plane motion with both revolution and rotation. When the input shaft rotates forward, the eccentric sleeve also rotates once, and the cycloid rotates one tooth in the opposite direction to obtain deceleration. Then, with the help of the W output mechanism, the low-speed rotation motion of the cycloid is transmitted to the output shaft through the pin shaft. In order to obtain a lower output speed.


Performance characteristics:
1. The cycloid reducer has a large reduction ratio and high efficiency: the reduction ratio of the first-stage transmission is 9~87, the reduction ratio of the two-stage transmission is 121~5133, and the multi-stage combination can reach tens of thousands, and the pin-tooth meshing system sets of rolling friction , There is no relative sliding on the meshing surface, so the first-stage deceleration efficiency reaches 94%.
2. The pinwheel reducer runs smoothly and has low noise: there are many pairs of teeth that are in contact at the same time during operation, the degree of coincidence is large, the operation is stable, the overload capacity is strong, the vibration and noise are low, and the noise of models of various specifications is low.
3. Reliable use and long life: Because the main parts are made of high-carbon alloy steel quenching treatment (HRC58-62), and then finely ground, and the cycloidal tooth and the needle tooth sleeve are meshed and transmitted to the needle tooth to form rolling friction. The coefficient is small, so that there is no relative sliding in the meshing area, and the wear is very small, so it is durable.
4. Compact structure and small size: Compared with other reducers of the same power, the weight and volume are more than 1/3 smaller. Because of the planetary transmission, the input shaft and output shaft are on the same axis to obtain the smallest possible size.

Installation requirements:
1. When installing couplings, belt pulleys, sprocket and other coupling parts on the output shaft of the cycloid reducer, direct hammering is not allowed, because the output shaft structure of the reducer cannot withstand the axial hammering force. You can use the shaft end screw hole to screw the screw into the coupling piece.
2. The shaft diameters of the output shaft and the input shaft are matched with GB1568-79.
3. The eyebolts on the reducer can only be used for lifting the reducer.
4. When the reducer is installed on the foundation, the elevation of the installation center line of the reducer, the levelness and the relevant dimensions of the connected parts should be calibrated.The concentricity of the calibrated moving shaft should not exceed the allowable range of the coupling.
5. When the reducer is calibrated, it can be carried out with steel spacers or cast iron spacers. The height of the spacers is not more than three, and it can also be carried out with a contract iron, but the reducer should be replaced with flat spacers after calibration.
6. The configuration of the cushion block should avoid causing deformation of the machine body, and should be arranged symmetrically on both sides of the foundation bolts, and the mutual distance can be sufficient to allow the water slurry to circulate freely during irrigation.
7. The irrigation of cement slurry should be dense, without bubbles, voids and other defects.

Conditions of Use:
1. Cycloidal pinwheel reducers are allowed to be used in continuous work situations, while allowing both forward and reverse rotation.Some models of cycloid reducers only allow one-way rotation.
3. The working positions of the horizontally installed cycloid reducer are all horizontal.The maximum horizontal tilt angle during installation is generally less than 15°.When it exceeds 15°, other measures should be taken to ensure adequate lubrication and prevent oil leakage.
4. The output shaft of the cycloid reducer cannot be subjected to large axial force and radial force, and other measures must be taken when there is a large axial force and radial force.

1. The horizontal cycloid reducer adopts oil pool lubrication under normal conditions, and the oil level can be kept in the middle of the oil sight window. When working conditions are bad and the ambient temperature is high, it can be lubricated by circulation.
2. Cycloid pinwheel reducer generally chooses 40# or 50# mechanical oil lubrication at room temperature. In order to improve the performance of the reducer and extend the service life of the cycloid pinwheel reducer, it is recommended to use 70# or 90# extreme pressure gears. Oil, lubricating oil should be reconsidered when working under high and low temperature conditions.
3. The vertical installation of the planetary cycloid reducer should strictly prevent the oil pump from cutting off the oil to avoid damage to the parts of the reducer.
4. When refueling, you can turn the breather cap on the upper part of the seat to refuel.When draining the oil, turn the drain plug at the bottom of the main seat to drain the dirty oil.There is no lubricating oil inside the reducer when it leaves the factory.
5. New oil should be replaced for 100 hours after the first refueling operation, (and clean the internal dirty oil), and then continue to work afterwards, and replace it every six months (8-hour work system). If the working conditions are bad, the oil change time can be appropriately shortened. Practice has proved that frequent cleaning and oil change of the reducer (such as 3-6 months) play an important role in prolonging the service life of the reducer.Lubricating oil should be replenished frequently during use.
6. The factory-made reducer has been greased and replaced every six months.The grease adopts aluminum disulfide-2# or 2L-2# lithium-based lubricating grease.
