Abstract

The invention discloses a novel expanding clamping type gapless plum blossom bearing bush. The bearing bush is characterized in that installation is carried out in an expanding clamping mode, and thesimple mode is gapless plum-blossom-shaped elastic connection; the size error of a hole and a transmission shaft is effectively eliminated through the expanding clamping mode; and connecting shafts and a reinforced nylon elastic ring are elastically connected, so that no rotation gap exists, and disassembly and assembly are convenient. The rotation features of forward rotation and reverse rotationare identical, and the torque is large. The invention relates to the technical field of bearing bushes. The bearing bush comprises the outer taper connecting shafts, inner taper sliding rings, fastening and adjusting screws, and the reinforced nylon plum-blossom-shaped elastic ring, wherein one outer taper connecting shaft, one inner taper sliding ring and the fastening and adjusting screws forman assembly; and each outer taper connecting shaft is provided with three grooves, so that the outer taper connecting shaft and the transmission shaft or a driven shaft are expanded to be connected together and are clamped through expanding. Two connecting shaft assemblies are in plum-blossom-shaped elastic connection. According to the bearing bush, installation and adjustment are simple, the rotating features are identical in the working running process, and thus the bearing bush is suitable for high-precision high-stability transmission, and the practicability is high.

Description

Technical field: [0001] The invention relates to a quincunx elastomer bearing bush that is suitable for a high-precision transmission motor and is connected by a displacement expansion sleeve expansion clip. It has zero rotation gap, high sensitivity, large transmission torque, can absorb vibration, and compensates radial, angular and axial deviations. The clockwise and counterclockwise rotation characteristics are exactly the same, which is suitable for high-precision size transmission bearings such as servo motors and stepping motors, and belongs to the technical field of bearings. Background technique: [0002] The bearing bush is a mechanical part used to connect the drive shaft and the driven shaft, so that the two shafts are jointly selected to transmit torque. In high-speed power transmission, the effective bearing bush has the functions of buffering, damping and improving the dynamic performance of the transmission mechanism. The bearing bush is composed of two halves, w...
