Adopt existing circular cone thrust bearing technology: the vertical air-air cooling asynchronous machine of YLKK560-8-800kW-3.3kV adopts SKF single-row circular cone spheric roller bearing 29348E (engine oil lubrication mode).Last lower guide bearing all adopts 6234 (big oil clearance) deep groove ball bearing grease lubrication mode.The circular cone spheric roller bearing has conical inner ring and outer ring raceway, and the circular cone spherical roller is arranged between the two.The projection line of all conical surfaces is all met in the same point of bearing axis.This gathering structure is particularly suitable for bearing radially and axial load.The axial load ability major part of bearing is by contact angle α decision, and the bigger axially load-bearing capacity of α angle is just high more.Angular dimension is represented with design factor e; The e value is bigger, contact angle is big more, and the applicability that bearing bears axial load is just big more.Single-row circular cone spheric roller bearing can be adjusted the size of play in installation process.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of medium-sized vertical machine of using the high thrust bearing arrangement is provided, and this kind vertical machine is simple in structure, volume-diminished, handling ease, manufacturing cost reduce.
The purpose of the utility model solves through following technical scheme:
The medium-sized vertical machine of this application high thrust bearing arrangement comprises base, casing, rotor, stator and is arranged on the air-air cooler on the casing; In casing, tightly be with the internal fan seat in advance in shaft extension end one side of armature spindle, non-shaft stretching end one side of armature spindle tightly is with cooler external fan seat, is inserted in upper and lower guide bearing respectively at the armature spindle two ends again; Said internal fan seat is provided with internal fan fan blade runner; Said casing upper end is provided with upper bracket, is provided with the thrust bearing oil drum in the upper fixed of upper bracket, is provided with the thrust bearing that cooperates with said armature spindle upper end in the said thrust bearing oil drum.
Above-mentioned thrust bearing is to be fixed in the thrust bearing oil drum through the thrust bearing seat of honour that is arranged on its upper and lower side and following of thrust bearing.
Above-mentioned upper bracket is with thrust bearing oil drum assembling, and the retaining oil drum penetrates armature spindle and following of thrust bearing in the thrust bearing oil drum, and assurance keeps off oil drum and armature spindle rotation space is even.
Above-mentioned thrust bearing is a segmental thrust bearing, this segmental thrust bearing following of thrust bearing of packing into, and both assemblings leave the 0.5mm gap, and to be that thrust bearing is on-stream influenced by thermal expansion metal to leave radially self-adjusting gap value; Quick detachable gap of 0.05mm and armature spindle assembling are pressed in the epivalve thrust bearing and the thrust bearing seat of honour behind hot jacket.
The thrust bearing that the utility model is used the medium-sized vertical machine of high thrust bearing arrangement adopts engine oil lubrication, for the rational oil drum of design bearing includes the anti-leakage of oil measure of thrust bearing.Last lower guide bearing still adopts traditional grease lubrication structure.Upper bracket well shape is supported, and is favourable to the top guide bearing ventilation and heat.Base connects lower guide bearing, improves the mutual utilization that thrust bearing and last lower guide bearing receive the major loop ventilating system, makes three's bearing temperature be controlled at zone of reasonableness.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, use the medium-sized vertical machine of high thrust bearing arrangement in this, comprise base 1, casing 2, rotor 3, stator 4 and be arranged on the air-air cooler 5 on the casing 2; In casing 2, tightly be with internal fan seat 9 in advance in shaft extension end one side of armature spindle 6, non-shaft stretching end one side of armature spindle 6 tightly is with cooler external fan seat 10, is inserted in upper and lower guide bearing 7,8 more respectively at armature spindle 6 two ends; Internal fan seat 9 is provided with internal fan fan blade runner; Said casing 2 upper ends are provided with upper bracket 11, are provided with thrust bearing oil drum 12 in the upper fixed of upper bracket 11, are provided with the thrust bearing 13 that cooperates with armature spindle 6 upper ends in the thrust bearing oil drum 12.Said thrust bearing 13 is to be fixed in the thrust bearing oil drum 12 with following 15 of thrust bearing through the thrust bearing seat of honour 14 that is arranged on its upper and lower side.Upper bracket 11 is with thrust bearing oil drum 12 assembling, and the retaining oil drums penetrate following 15 of armature spindle 6 and thrust bearing in the thrust bearing oil drum 12, and assurance keeps off oil drum and armature spindle 6 rotation spaces are even.
