Abstract
The utility model discloses a speed reducer assembly. The speed reducer assembly comprises a box body. A transmission shaft is arranged inside the box body. The peripheral portion of the transmission shaft is sleeved with a bearing. An end cap is arranged at one end of the box body. An oil pump is arranged outside the end cap. A gear ring which is in coaxial linkage with the transmission shaft is arranged inside the end cap. A sun gear which is in coaxial linkage with the oil pump is coaxially arranged inside the gear ring. A plurality of planetary gears are arranged between the sun gear and the gear ring. Each planetary gear is meshed with the periphery surface of the sun gear and the inner periphery surface of the gear ring. When the speed reducer assembly works, a planetary gear train is formed by the gear ring, all the planetary gears and the sun gear in a mutually matched mode, the planetary gear train can improve the rotation speed transmitted to the oil pump from the transmission shaft so that the rotation speed of the oil pump can be improved correspondingly, as a result, the output speed of lubrication oil is improved, and therefore the overall lubrication efficiency of a speed reducer is improved correspondingly.

Background technique
In general speed reducer running, conventionally need to use lubricant oil that the main components such as each friction member and casing are lubricated and are lowered the temperature, pressure lubrication is a kind of common speed reducer lubricating system, and it normally utilizes oil pump that lubricant oil is pressed into corresponding component lubrication face place by oil pipe.Along with improving constantly of working strength, people also have higher requirement to the lubrication effect of pressure lubrication.
In current existing speed reducer working procedure, along with operating mode changes, working strength increases, the lubricating efficiency of original pressure lubrication cannot meet the needs of high-strength working, this just needs by improving the rotating speed of oil pump, increase the output speed of lubricant oil, and then improve the lubricating efficiency of whole speed reducer, thereby meet the intensive work needs of speed reducer.
Therefore the lubricating efficiency that, how to improve speed reducer is the important technological problems that those skilled in the art need to solve at present.
Model utility content
The purpose of this utility model is to provide a kind of speed reducer assembly, and the lubricating efficiency of this speed reducer assembly is higher.
For solving the problems of the technologies described above, the utility model provides a kind of speed reducer assembly, comprise casing, the inside of casing is provided with transmission shaft, the peripheral part of described transmission shaft is set with bearing, the end of described casing is provided with end cap, the arranged outside of described end cap has oil pump, the inner side of described end cap is provided with the gear ring with described transmission shaft coaxial linkage, the inner side of described gear ring is coaxially arranged with the sun gear with described oil pump coaxial linkage, between described sun gear and described gear ring, be provided with several rows star-wheel, and described in each, planet wheel is meshed with the outer circumferential face of described sun gear and the inner peripheral surface of described gear ring respectively.
Preferably, described planet wheel is three.
Relative above-mentioned background technology, speed reducer assembly provided by the utility model, comprise casing, the inside of casing is provided with transmission shaft, the peripheral part of described transmission shaft is set with bearing, the end of described casing is provided with end cap, the arranged outside of described end cap has oil pump, the inner side of described end cap is provided with the gear ring with described transmission shaft coaxial linkage, the inner side of described gear ring is coaxially arranged with the sun gear with described oil pump coaxial linkage, between described sun gear and described gear ring, be provided with several rows star-wheel, and described in each, planet wheel is meshed with the outer circumferential face of described sun gear and the inner peripheral surface of described gear ring respectively.In working procedure, by described gear ring, complement each other to form planetary gear train between planet wheel and described sun gear described in each, this planetary gear train can increase the rotating speed that is passed to described oil pump place by described transmission shaft place, so that the corresponding raising of the rotating speed of described oil pump, thereby its lubricant oil output speed is improved, and then make the whole lubricating efficiency of described speed reducer be able to corresponding raising.
