The invention relates to the technical field of reducers, and relates to a planetary reducer and a transmission system. The planetary reducer comprises a shell, a power input shaft and a power outputshaft. The power input shaft and the power output shaft are both arranged in the shell, and the power output shaft and a power head gear shaft are coaxially arranged. In particular, a first gap and asecond gap are formed in the end, toward the power input shaft, of the power output shaft, the second gap is located in the first gap, and the size of the first gap is larger than that of the second gap. A protrusion matched with the second gap is arranged at the end, toward the power output shaft, of the power input shaft, and the size of the protrusion is smaller than that of the second gap. After the planetary reducer is mounted, a clearance exists between the power input shaft and the power output shaft, a lubricating agent is arranged in the clearance so that a fluid bearing can be formedbetween the power output shaft and the power input shaft, abrasion between the power output shaft and the power input shaft is reduced, and the service life of the planetary reducer is prolonged. Compared with the prior art, a transmission system has the beneficial effects.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular, to a planetary reducer and a transmission system. Background technique [0002] The principle of the planetary reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. The gear with a small number of teeth on the transmission shaft of the planetary reducer meshes with the large gear on the output shaft to achieve the purpose of deceleration. Planetary reducer planets, as the name suggests, revolve around the sun, so a planetary reducer is like this, a reducer with three planetary wheels revolving around a sun wheel. With the continuous rapid development of the planetary reducer industry, more and more industries and different enterprises have applied the planetary reducer. [0003] However, the planetary reducer in the prior art w...
