A double planetary gear reducer floating positioning mechanism

Abstract

The invention discloses a floating positioning mechanism of a double-planet-gear speed reducer, belonging to the technical field of planet-gear speed reducers. The floating positioning mechanism solves the problem that when an existing planet-gear speed reducer frequently rotates forwards and backwards, structures are prone to rigid deformation, which leads to widening of gaps between the structures. The floating positioning mechanism of the invention comprises a bottom supporting mechanism, wherein two main body shells are mounted on the upper end surface of the bottom supporting mechanism; abottom sealing strip is installed on one side of one main body shell, an end locking ring is installed on the outer side of one end of the main body shell, the main body shell is connected with the end locking ring through an end sealing ring, and an internal transmission mechanism is installed on the inner side of the main body shell; and a floating positioning mechanism body is installed on theinner side of the internal transmission mechanism. Through supporting and pre-tightening of structures, the floating positioning mechanism can effectively improve the bearing capacity of the structures, and avoids the phenomenon that the structures float due to the fact that gaps between the structures are increased due to structural deformation.

Description

technical field [0001] The invention relates to the technical field of planetary gear reducers, in particular to a floating positioning mechanism of a double planetary gear reducer. Background technique [0002] With the rapid development of social economy, planetary gear reducer is also called planetary reducer and servo reducer. In the reducer family, planetary reducer has many advantages such as small size, high transmission efficiency, wide deceleration range and high precision. It is widely used in transmission systems such as servo motors, stepping motors, and DC motors. Its function is to reduce the speed and increase the torque and reduce the moment of inertia ratio of the load / motor under the premise of ensuring precision transmission. [0003] However, the structure of the existing planetary reducer is prone to rigid deformation during frequent forward and reverse rotations, which leads to a larger gap between the structures; therefore, it does not meet the existin...
