Abstract
The utility model provides a driven chain wheel mechanism of a lifter. The driven chain wheel mechanism of the lifter is high in stability and comprises a chain wheel and a support. A bearing seat is fixedly installed on the support. Two bearings are arranged in the bearing seat. An inner ring shaft sleeve and an outer ring shaft sleeve are fixedly clamped between the two bearings. A locating portion is arranged at one end of the bearing seat and a bearing cap is fixedly connected to the other end of the bearing seat. The bearing cap abuts against an outer ring of one bearing. The locating portion abuts against an outer ring of the other bearing. A rotary shaft is sleeved with inner rings of the two bearings simultaneously. One end, close to the bearing cap, of the rotary shaft is provided with a limiting portion abutting against the inner ring of one bearing and the other end, protruding out of the bearing seat, of the rotary shaft is fixedly connected with the chain wheel. A limiting shaft sleeve is fixedly clamped between one side of the chain wheel and the inner ring of the other bearing and the other side of the chain wheel is provided with multiple screwing nuts.
Description
Technical field
A kind of driven sprocket mechanism of the utility model, relates in particular to a kind of driven sprocket mechanism of elevator.
Background technology
Elevator is one of crucial portion machine in automation stacking production line, mainly contains lifting table, driving device and balance weight body and forms.Transmission device is the propulsion source that lifting table is realized dipping and heaving, conventionally adopts chain-drive mode, under the positive and negative turning effort of reducing motor, by drive sprocket, chain and driven sprocket, makes lifting table realize upper and lower motion.
In the motion process of lifting table, driven sprocket bears larger radial pull and a small amount of axial tension all the time, thereby causes less stable, and the stability that therefore guarantees driven sprocket is in transmission process, to need one of key technical problem solving.
