Conveyor drive mechanism provided with hexagonal through shaft and motor adapter sleeve shaft

Abstract

The invention discloses a conveyor drive mechanism provided with a hexagonal through shaft and a motor adapter sleeve shaft. The conveyor drive mechanism comprises the hexagonal drive through shaft, two independent drive units, the motor adapter sleeve shaft and a motor. One end of the motor adapter sleeve shaft is a round shaft end and is provided with a key groove. The orthogonal hollow round shaft motor is connected with the round shaft end of the motor adapter sleeve shaft through a flat key. A hexagonal groove is formed in the other end of the motor adapter sleeve shaft. The hexagonal drive through shaft is inserted into the hexagonal groove of the motor adapter sleeve shaft. A hexagonal drive through shaft main body penetrates through the two independent drive units. According to the conveyor drive mechanism, the motor adapter sleeve shaft is adopted for being connected with the motor and the through shaft, the structure is simple, few parts are used, installing and maintaining are easy, the manufacturing cost is low, and the conveyor drive mechanism has a certain function of compensating the relative deviation of two shafts. The through shaft, a chain wheel and the motor sleeve shaft are connected in a hexagonal manner, compensation to the concentricity deviation is ensured, and the problem that when the straight round shaft is adopted, a motor hole and the chain wheel are not concentric is solved.

Description

technical field [0001] The invention relates to the technical field of automatic transportation systems, in particular to a conveyor driving mechanism with a hexagonal through shaft and a motor adapter sleeve shaft. Background technique [0002] At present, the drive mechanism of the known chain conveyor usually adopts a straight-through round shaft, the sprocket is a round hole with a keyway, and the motor is connected to the straight-through round shaft with a vertical hollow round shaft and a flat key. The defect of the above technical solution is that there is a problem of over-positioning, and the requirements for machining accuracy and the coaxiality of the straight-through circular shaft are very high. If the coaxiality exceeds the tolerance, it will cause a large force on the straight-through round shaft, which will affect the motor and cause oscillation. , The internal parts of the drive mechanism are easily damaged. [0003] There is also a chain conveyor drive me...

AI Technical Summary

Problems solved by technology

The defect of the above technical solution is that there is a problem of over-positioning, and the requirements for machining accuracy and the coaxiality of the straight-through circular shaft are very high. If the coaxiality exceeds the tolerance, it will cause a large force on the straight-through round shaft, which will affect the motor and cause oscillation. , the internal parts of the drive mechanism are easily damaged

[0003] There is another chain conveyor driving mechanism, which adopts a split shaft drive. In addition to the linkage shaft, it needs to transmit torque through two adapter sleeves and two independent drive shafts. Too many adapter parts result in low transmission efficiency, and Excessive number of parts increases manufacturing costs

[0004] There is also a chain conveyor drive mechanism that uses a motor with a hollow shaft with hexagonal holes. This type of motor does not belong to the conventional brand type on the market and requires special customization. The price is high and the procurement cycle is long.
