Central transmission thickener driving device

Abstract

The invention discloses a central transmission thickener driving device, which comprises a fixed seat, a rotating frame, a slewing bearing , low-speed large-torque speed reducers, guide wheel sets, aguide pipe shaft and a rake lifting oil cylinder, wherein the guide pipe shaft is fixed to the upper portion of the fixed seat, the rotating frame is installed on the fixed seat through the slewing bearing and connected to the guide pipe shaft in a sleeving mode, the low-speed large-torque speed reducers are installed on the rotating frame, connected with the slewing bearing and drive the slewingbearing to rotate, the at least two low-speed large-torque speed reducers are symmetrically arranged; the guide wheel sets and the rake lifting oil cylinder are fixed to the upper portion of the speedreducer box body, guide grooves are formed in the guide pipe shaft, the guide wheels of the guide wheel sets are located in the guide grooves, and at least two guide wheel sets are symmetrically arranged. According to the invention, hydraulic multi-point driving is adopted, stepless speed regulation is achieved, the mechanical strength is high, the stability is good, the overload protection function is achieved, and different technological requirements are met; and the equipment is high in operation stability, low in operation failure rate, low in maintenance frequency, long in service life and low in overall operation cost.

Description

technical field [0001] The invention relates to a driving device of a central transmission concentrator, which belongs to the technical field of concentrators. Background technique [0002] Due to the design of the transmission device in the existing large-diameter concentrator, the driving torque is small, the rake guide is unstable and not smooth, and the operation failure rate is high. Therefore, the frequency of use and maintenance is high, the service life of the equipment is low, and the overall operating cost is too high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a driving device for a central transmission concentrator. [0004] In order to achieve the above purpose, the technical means adopted in the present invention is: a driving device of a central transmission concentrator, including a fixed seat, a rotating frame, a slewing bearing, a low-speed high-torque reducer, a gu...
