Synchronous driving mechanism of bottom frame of movable rack

Abstract

The invention discloses a synchronous driving mechanism of a bottom frame of a movable rack. The synchronous driving mechanism comprises the bottom frame, wherein the bottom frame is a synchronous transmission bottom frame, the synchronous transmission bottom frame comprises a transmission middle shaft, two transmission side shafts which are arranged on two sides of the transmission middle shaft,and iron rollers which are connected to the two ends of the transmission side shafts, the synchronous transmission mechanism is characterized in that the transmission middle shaft is in transmission connection with the transmission side shafts through corresponding transmission synchronous belt wheels and transmission synchronous belts of the transmission synchronous belt wheels, and a coordination balance synchronous belt is further connected between the two transmission side shafts through corresponding coordination balance synchronous belt wheels. The synchronous driving mechanism of the ofthe bottom frame of the movable rack is simple in structure, simple and convenient to use and operate, convenient to maintain, high in transmission efficiency, good in transmission performance, highin running environment adaptability, convenient to maintain, free of lubrication, low in maintenance cost, low in operation noise and stable in operation.

Description

technical field [0001] The invention relates to a synchronous drive mechanism for a compact shelf chassis. Background technique [0002] Most of the existing compact rack drive mechanisms are chain-type transmission structures for the hand-operated mechanism, and chain or gear structure for the driving wheel transmission of the underframe. This type of transmission structure has high manufacturing and operating costs, is easy to wear and stretch, has poor transmission stability, and is prone to additional dynamic load, vibration, impact and noise during operation, and has poor adaptability to rapid reverse transmission. The transmission gear meshing structure introduced later has higher manufacturing cost, complicated manufacturing process, inconvenient maintenance, poor adaptability to the operating environment, high operating noise, poor adaptability to speed change, and the overall manual mechanism is heavy and bulky. As for the drive of the chassis, the existing transmi...

Problems solved by technology

This type of transmission structure has high manufacturing and operating costs, is easy to wear and stretch, and has poor transmission stability. It is prone to additional dynamic load, vibration, impact and noise during operation, and its adaptability to rapid reverse transmission is poor.

The transmission gear meshing structure introduced later has higher manufacturing cost, complicated manufacturing process, inconvenient maintenance, poor adaptability to the operating environment, high operating noise, poor adaptability to speed change, and the overall manual mechanism is heavy and bulky

As for the drive of the chassis, the existing transmission method has a difference in twisting stress and deformation at both ends of the transmission side shaft, which makes the driving force at both ends unbalanced and different in speed, which can easily cause instability such as swinging and vibration when the compact rack is in motion.
