Novel tooth-connected type elastic bearing bush

Abstract

The invention discloses a novel tooth-connected type elastic bearing bush. In working time, when driven equipment breaks down and clamps the bearing bush, a part can be broken so that the function ofthe bearing bush is invalid, and the phenomenon that driving equipment is stalled for a long time and becomes damaged can be prevented. The invention relates to the technical field of bearing bushes;the bearing bush comprises two connecting shafts, a nylon gear sleeve, and four fastening screws, wherein each connecting shaft is provided with two step gears, and the large ends of the connecting shafts are cylindrical straight gears; and the shape of the nylon gear sleeve is cylindrical, an inner hole is three step gears, the size of a middle hole is relatively reduced to realize the axial positioning effect, the holes in the two ends are straight teeth, and the tooth modulus specifications are the same as those of connecting shaft teeth and are in standard fit. According to the bearing bush, the installation and adjustment are simple, the elastic fine adjustment can be realized during operation, the material property can reduce noise, vibration is reduced, passive protection is achieved when transmission equipment is abnormal, and the practicability is high.

Description

Technical field: [0001] The invention relates to a bearing bush with wide application range, low noise, simple structure, convenient maintenance, easy disassembly and assembly, small transmission efficiency loss and long service life, and belongs to the technical field of bearing bushes. 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, which are respectively connected with the driving shaft and the driven shaft. Many general power machines are connected to the working machine by means of bearing bushes. There are many types of bearing bushes. The relative position or position changes of the two shafts to be installed can be divided ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the commonly used bearing bushes require high precision, and a bearing bush specification is only suitable for the corresponding shaft connection; and during long-term operation, the driven shaft is stuck and unable to rotate due to equipment failure, and the motor in the transmission part of the active system is usually burned and damaged.
