Embodiment
[0011] Embodiment: An X-type standard planetary gear reducer with automatic axial clearance compensation function. The reducer is composed of an input shaft 1, an output shaft 2, a high-speed planetary gear train and a low-speed planetary gear train. The high-speed planetary gear The system includes the first ring gear 3, the first planetary gear 4, the first planet carrier 5 and the first sun gear 6, and the low-speed planetary gear train includes the second ring gear 7, the second planetary gear 8, and the second planet carrier 9 and the second sun gear 10, the input shaft 1 drives the first sun gear 6 to rotate, the first sun gear 6 is meshed with several first planetary gears 4, and the first planetary gear 4 and the first planetary carrier 5 can be rotated and positioned At this time, the first planetary gear 4 not only rotates around its own axis but also revolves around its common axis. Since the first planetary gear 4 is installed on the first planetary carrier 5, it dr...

The invention discloses an X type standard planetary reducer with an automatic axial clearance compensation function. An input shaft drives a first sun wheel to rotate; the first sun wheel is in meshing transmission with a plurality of first planet wheels; the first planet wheels and a first planet carrier can realize rotary positioning; the first planet carrier is meshed with a second sun wheel; the second sun wheel is in meshing transmission with a plurality of second planet wheels; the second planet wheel and second planet carrier can realize rotary positioning; the second planet carrier can drive an output shaft to rotate; a first inner gear ring and a second inner gear ring are connected fixedly; elastic elements are arranged at one end, facing towards the output shaft, of the second sun wheel; and two axial ends of each elastic element closely abut against the second sun wheel and an end wall of the second planet carrier respectively. According to the X type standard planetary reducer, the elastic elements release elasticity to compensate gas among central shafts of all levels of transmission mechanisms, so that all levels of the transmission mechanisms are closely contacted; the structure is compact; the X type standard planetary reducer has better vibration attenuation and floating effects, and noise produced in an operation process of the reducer is avoided; and the performance of the whole reducer is improved.
Description
technical field [0001] The invention relates to a planetary gear reducer, in particular to an X-type standard planetary gear reducer with an axial gap automatic compensation function. Background technique [0002] In recent years, the country has gradually increased its investment in the field of infrastructure construction, metallurgy, electric power, construction machinery, energy and other industries have accelerated the development, and the market demand for reducers in related industries has also gradually expanded. As a special transmission form of the reducer, the planetary gear reducer is widely used in the transmission system of various industries due to its large load capacity, small size and high efficiency. At present, the standard planetary gear reducer has axial A certain gap, through this structure, can avoid axial collision between stages during operation, causing wear and interference, thus affecting the performance of the whole machine.
