Abstract
The utility model relates to a detection fixture for a single-bearing generator, and relates to a motor detection device. The detection fixture comprises a flange bearing pedestal, a step shaft and a belt pulley, and is characterized in that: a central blind hole is formed in the left end of the step shaft and is sleeved at the shaft end of a main shaft in a movable fit mode; the flange bearing pedestal is in a shape of an annular disc; a bearing is fixedly sleeved in a central hole of the annular disc; a bearing hole is sleeved in an excircle of a shaft body on the left section of the step shaft in a movable fit mode; a one-piece convex circular ring rabbet is arranged on the left end face of the annular disc and is sleeved in an inner hole at the right end of a motor impeller protection plate flange; bolts pass through a plurality of through holes of the annular disc and are subjected to butted joint with the impeller protection plate flange fixedly; the belt pulley is a solid wheel; the central blind hole is formed in the left end face of the belt pulley and is sleeved on an excircle of a shaft on the right section of the step shaft; the six bolts pass through through holes of the belt pulley and through holes of the step shaft and are screwed in a threaded hole in the shaft end of the main shaft, so that the belt pulley, the step shaft and the main shaft are connected fixedly. According to the detection fixture, a structure and installation processes are simplified, the length of the step shaft is shortened, the flange bearing pedestal is changed into a single-disc body, and the axial length of the flange bearing pedestal is reduced greatly.
Description
Technical field:
The utility model relates to generator detection device, and particularly a kind of single shaft holds the detection frock of generator.
Background technology:
The connection of genset is improved to single shaft by early stage transition disc through the spring column pin connected mode and holds hard connection.Therefore, present electric generator structure that is to say bearing is installed on the commutator end bearing support bracket that the motor front end is not installed bearing mostly for single shaft holds.The generator assembling finishes and must detect each item serviceability index, need testing generator be installed on the worktable during test, rotates the aptitude test data through the belt pulley drawing generator by another motor that is fixedly mounted on the support.Thereby the detection frock of bearing, belt pulley need be arranged at generator main axle head mounting strap, just can carry out performance test.
Existing generator main axial end all is provided with six screws and is used for docking with diesel engine, and the casing outer periphery is equipped with impeller protection plate flange and is used for body and docks with diesel engine.The existing frock that detects is that a transition circle disk body is implemented to dock through six bolts and spindle nose; Then a step axle docks with the transition disk; Again a flange form bearing seat is docked with electric motor with vane wheel protection plate flange; Dead eye on the flange form bearing seat is inserted in step axle stage casing simultaneously, then again belt pulley is inserted in step axle leading portion, accomplishes and detects preposition suit operation.
This structure is through transition disc, step axle pad position, makes that bearing position external shift quantity is big, arm length, increase main shaft moment of flexure, and the flange form bearing seat axial elongation of twin nuclei, and volume is big and cost is high.Say that from installation procedure want secondary butt joint, secondary suit, twist two groups of bolts, operation is many and efficient is low.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, the detection frock that provides a kind of single shaft to hold generator.
The scheme of the utility model is: comprise flange form bearing seat, step axle, belt pulley, it is characterized in that: step axle left end is provided with central blind hole, and this central blind hole is linked in main-axis end movingly; The flange form bearing seat is the annulus plate-like; A circle ring disk medium pore internal fixation cover unification bearing; This dead eye is linked on the section axis body cylindrical of a step axle left side movingly, and the circle ring disk left side is provided with the dome ring seam of disjunctor, and this dome ring seam cylindrical is enclosed within the electric motor with vane wheel protection plate flange right-hand member endoporus movingly; The circle ring disk outer circumference surface is provided with some through holes, and bolt passes said some through holes and implements to dock fixing with impeller protection plate flange; Belt pulley is a solid wheel; Its left side is provided with central blind hole; This central blind hole is enclosed within on the right section axle of the step axle cylindrical movingly; Six bolts pass belt pulley respectively corresponding to the through hole of spindle thread hole setting, the through hole that the step axle is provided with corresponding to the spindle thread hole, stubborn being combined in the threaded hole of main-axis end, implement the fixed connection of belt pulley, step axle, main shaft.
The advantage of the utility model is: designs simplification, and installation procedure is also simplified, and has shortened the step shaft length, the flange form bearing seat becomes the single-deck body by the dicyclo body, and axial length greatly reduces.Not only whole frock axial length shortens dramatically, and has improved mechanical property, has reduced cost.
