Multi-direction position deviation compensating type bearing bush

Abstract

The invention discloses a multi-direction position deviation compensating type bearing bush, and relates to the technical field of bearing bushes. The multi-direction position deviation compensating type bearing bush comprises a connecting shaft, a connecting flange, a transmission rod, an axial screw, an inner hexagonal fastening screw, a headless inner hexagonal fastening screw and a movable connecting rod, wherein an opening groove is formed in one end of the connecting flange; flat wires are arranged at one end of the movable connecting rod, and the other end of the moving connecting rod is provided with an opening groove in the vertical direction; the flat wires at the movable connecting rods are movably matched with the opening groove in the connecting flange; and the opening grooveis movably matched with flat wires of the transmission rod. The position deviation of the bearing bush in a plurality of directions can be compensated through four movable joints. The multi-directionposition deviation compensating type bearing bush is simple in structure, reasonable in design, high in rigidity, low in manufacturing complexity, and low in practicability; and the transmission linkage is direct and effective; the noise is low and the vibration is small during working; the mounting and repairing are convenient; various error in equipment use can be automatically removed through the design; and the practicability and the performance are high.

Description

Technical field: [0001] The invention relates to a bearing bush with wide application range, compensation of up, down, left and right angle position deviation, low noise, simple structure, strong rigidity, convenient maintenance, easy assembly and disassembly, small transmission efficiency loss and long service life, belonging to the technical field of bearing bushes. Background technique: [0002] The bearing bush is a mechanical part used to connect the transmission shaft and the driven shaft so that the two shafts can be selected together to transmit torque. In high-speed power transmission, the effective bearing pad has the functions of buffering, shock absorption and improving the dynamic performance of the transmission mechanism. The bearing pad consists of two halves, which are respectively connected with the driving shaft and the driven shaft. Many general power machines are connected with the working machine by means of bearing bushes. There are many types of bear...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the commonly used bearing bushes have high precision requirements, and a bearing bush specification is only suitable for matching shaft connections; and when the bearing bushes are installed, the center position of the drive shaft and the driven shaft installation has a high requirement for the center deviation, otherwise the transmission equipment will be prone to noise. The comprehensive vibration is high, the transmission efficiency loss is large, and the transmission equipment is prone to heat and even stuck, resulting in equipment damage

The bearing bush cannot compensate for the position offset of the transmission equipment caused by external force during work, without affecting the transmission performance
