Description
Technical Field
The utility model relates to the technical field of mechanical equipment, especially a right angle planetary reducer.
Background
The speed reducer is an independent closed transmission device between the prime motor and the working machine and is used for reducing the rotating speed and increasing the torque so as to meet the working requirement. The reducer converts the higher rotational speed of the input shaft to the lower rotational speed of the output shaft through a transmission member (typically a gear or worm).
The bevel gear of the existing right-angle reducer is fixed, and after equipment runs for a period of time, the meshing state between the bevel gears is deteriorated due to vibration or abrasion, so that the right-angle reducer cannot be in the optimal meshing state for a long time, and the performance of the right-angle reducer is affected; the solution now commonly used is to replace the bevel gear with a new one, which results in increased use costs.
In addition, because the output shaft needs to drive the actuating component, the output shaft often receives a large radial force, a bearing of the output shaft is generally supported by one bearing or a pair of tapered roller bearings arranged oppositely in the existing speed reducer, the bearing is arranged on one side of the transmission component, even if the pair of bearings is arranged, the distance between the two bearings is very short, when the front end (the part connected with the actuating component) of the output shaft receives the large radial force, the rear end of the output shaft generates deflection with a certain amplitude, the vibration and the noise of the equipment are aggravated, and the service life of the equipment is influenced.
