Abstract
Screw conveyer of shield machine driver train relates to the mechanism for driving shield machine conveyor screw.Mainly for solving existing screw conveyer of shield machine driver train output torque is little and sealing effectiveness is poor problem and designing.It comprises screw drives framework, gland is fixed on screw drives framework, axle drive shaft in screw drives framework is welded on helicallobe, helicallobe is contained on main shaft of screw conveyor, axle drive shaft and cylindrical roller bearing outer ring are fixed, cylindrical roller bearing inner ring is fixed on screw drives framework, the inner ring of cylindrical roller bearing and the inwall of gland there are grommet type seals and seal ring dottle pin, gland inwall and cylindrical roller bearing inner ring there is seal cover cap, the tooth of the transmission gear and cylindrical roller bearing that are fixed on the HM Hydraulic Motor on screw drives framework engages, speed sensor on screw drives framework, gland and screw drives framework there is hydraulic oil inlet.Advantage is that output torque is large, good sealing effect.
Description
Technical field:
The utility model relates to the mechanism for driving shield machine conveyor screw.
Background technology:
The driver train of the conveyor screw of existing shield machine provides driving power by a HM Hydraulic Motor, and output torque is less, causes Emergence low.Its drive part sealing effectiveness is bad, and because drive part directly contacts with earth, often generation earth enters into the situation in drive part, causes drive part stuck.In addition because drive part inner sealing is without pressure support, seal ring is fragile, need often change, and delays normally carrying out of production.
Summary of the invention:
It is large that technical problem to be solved in the utility model is to provide a kind of output torque, drive part good sealing effect, the non-damageable screw conveyer of shield machine driver train of seal ring.
Above-mentioned purpose is achieved in that it comprises two HM Hydraulic Motor and screw drives framework, gland is bolted on screw drives framework, axle drive shaft is had in screw drives framework, axle drive shaft is welded on helicallobe, helicallobe is arranged on the main shaft of conveyor screw, also cylindrical roller bearing is provided with in screw drives framework, axle drive shaft is connected and fixed by the outer ring of bolt and cylindrical roller bearing, the inner ring of cylindrical roller bearing is fixed on screw drives framework, the inner ring of cylindrical roller bearing is provided with the grommet type seals of some roads, the seal ring dottle pin of annular is provided with between adjacent twice grommet type seals, described grommet type seals contacts with axle drive shaft, the internal diameter of described seal ring dottle pin is greater than the internal diameter of grommet type seals, the seal ring that twice are adjacent and the seal ring dottle pin between them and the space formed between axle drive shaft are hydraulic oil channel, hydraulic oil channel is built with hydraulic oil, the inwall of gland is also provided with the grommet type seals of some roads, also the seal ring dottle pin of annular is provided with between adjacent twice grommet type seals described in this, described grommet type seals contacts with axle drive shaft, the internal diameter of described grommet type seals dottle pin is greater than the internal diameter of grommet type seals, the seal ring that twice are adjacent and the seal ring dottle pin between them and the space formed between axle drive shaft are hydraulic oil channel, hydraulic oil channel is built with hydraulic oil, gland inwall is fixed with seal cover cap, seal cover cap is positioned at the right side of the grommet type seals of the rightmost side on gland inwall, seal cover cap withstand on be positioned at the rightmost side on gland inwall grommet type seals on, cylindrical roller bearing inner ring is also fixed with seal cover cap, seal cover cap described in this is positioned at the left side of the grommet type seals of the leftmost side on cylindrical roller bearing inner ring, seal cover cap withstand on be positioned at the cylindrical roller bearing inner ring leftmost side grommet type seals on, two HM Hydraulic Motor are all fixed on screw drives framework, the transmission gear of two HM Hydraulic Motor all engages with the tooth of cylindrical roller bearing, screw drives framework is equipped with speed sensor, the gland at corresponding each hydraulic oil channel place and screw drives framework are all respectively equipped with hydraulic oil inlet.
The utility model has the advantages that: owing to being provided with two HM Hydraulic Motor, so output torque is large, owing to being filled with hydraulic oil between adjacent twice grommet type seals, can ensure that the rear portion of per pass seal ring all exists certain pressure, add the safety of grommet type seals, grommet type seals is not fragile, ensure that the sealing effectiveness of drive part, earth can not enter into bearing and gear, there will not be stuck phenomenon.
Accompanying drawing illustrates:
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is A-A view of Fig. 1.
