An adjustable center coupling

Abstract

The invention relates to a center-adjustable coupling. The center-adjustable coupling comprises an auger connector, a speed reducer output shaft, a left connecting sleeve and a right connecting sleeve, wherein a left connecting sleeve flange is arranged at the periphery of the left end of the left connecting sleeve, the left connecting sleeve flange is fixedly connected with the right end of the auger connector through a left connecting sleeve screw, and outer crowned teeth are arranged at the periphery of the right end of the left connecting sleeve; inner crowned teeth are arranged on the inner wall of the right connecting sleeve, the inner crowned teeth are engaged with the outer crowned teeth, and the outer circumference of the right end surface of the right connecting sleeve is fixedly connected with the outer circumference of the speed reducer output shaft through a right connecting sleeve screw; a mandrel extending towards the left and sharing an axis with the speed reducer output shaft is connected at the center of the left end surface of the speed reducer output shaft; the mandrel is inserted in an inner cavity of the left connecting sleeve, a middle knuckle bearing is mounted at the mandrel shoulder part of the mandrel, and a left angle bearing and a right angle bearing are mounted on the middle knuckle bearing; and the left angle bearing and the right angle bearing are positioned in bearing holes of the left connecting sleeve and are positioned through glands and locking nuts. The coupling is center-adjustable and can bear bi-directional axial force.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an adjustable center shaft coupling, and belongs to the technical field of transmission mechanisms. Background technique [0002] Grain, soybean meal and other materials are usually placed in silos for long-term storage, and the bottom of the silo is equipped with a discharge machine for outputting materials. The discharge port of the silo is located at the bottom center of the silo. The main shaft system of the discharge machine includes a reducer, a coupling, an auger shaft and a tail end bearing. The reducer is located on the axis of the silo, and the output shaft of the reducer passes through the coupling. The shaft device is connected with the driving end of the auger shaft, and the outer end of the auger shaft is supported on the circular guide rail through the tail end bearing. When discharging, the reducer drives the auger shaft to rotate through the coupling, and the auger shaft conv...

Problems solved by technology

[0004] Since the coupling of the silo machine in the prior art cannot withstand the reverse axial force generated by the reversal, the silo roof can only be lifted, and it takes half a month to a month to remove the silo. The material is cleaned up, and then the auger shaft can be restarted, which is time-consuming and laborious
