Abstract
The utility model relates to a novel rotor collector-ring press-mounting pressure head, comprising a pressure-head fixing base, an inner pressure head and a pressure-head fixing sleeve successively connected with each other. A thrust bearing is arranged between the pressure-head fixing base and the inner pressure head. A spring is mounted between the inner pressure head and the pressure-head fixing sleeve. The novel rotor collector-ring press-mounting pressure head provided by the utility model adopts sectional type design and disposes the thrust bearing between the pressure-head fixing base and the inner pressure head, so that the collector-ring press-mounting pressure head can enable the pressure head has effects of rotation and aligning in a press-down process. The spring is mounted between the inner pressure head and the pressure-head fixing sleeve, so that the pressure head has certain buffer effect in a process that the pressure head is pressed down and just contacted with the collector ring. The press-mounting pressure head can adjust a position of the collector ring, so that an inner-hole shaft center and a shaft center of a shaft approach consistence when the collector ring is pressed down and that the collector ring can't be broken in the press-down process is guaranteed.
Description
Technical field
The utility model relates to the frock pressure head that a kind of auto parts and components are used, and relates in particular to a kind of novel rotor collector ring and press-fits pressure head.
Background technology
The endoporus material of collector ring is a resin, and axle is a steel, behind the annular knurl collector ring is pressed onto on the axle on the axle.
Through regular meeting the situation that collector ring breaks and lost efficacy appears in traditional press-fiting in the process; Find because the frock rigging error through field test; The rotor component rigging error; The endoporus axle center was inconsistent with the axle center of axle when the existence that the not stressed anteposition of collector ring is put reason such as inclined to one side can cause collector ring to press down, thereby caused collector ring unbalance stress in the process of pressing down and the collector ring inefficacy of breaking finally occurs.
Tradition press-fits motor easy loosening situation about losing efficacy of collector ring that takes place in the service firing process that the collector ring mode is produced.Cause this failure reasons to be: the axis parallel of actual straight burr that on axle, rolls out and discord axle; But be equivalent to helix; This causes collector ring in the process of pressing down, except that the resistance of receiving downward pressure and making progress, also to receive torsional interaction, can not rotate when traditional pressure head presses down, and collector ring is subdued by force; Because the collector ring material is more crisp, the straight burr that forms on the collector ring endoporus can't be meshed with the straight burr on the axle.
Summary of the invention
The utility model has the pressure head of letting and in the process of pressing down, can rotate and aligning in order to solve defective and the deficiency that above-mentioned prior art exists, to provide, thereby the novel rotor collector ring that can cushion and regulate the collector ring position press-fits pressure head.
The technical scheme of the utility model: a kind of novel rotor collector ring press-fits pressure head; Comprise the pressure head holder, inner ram and the pressure head fixed cover that connect successively; Be provided with thrust bearing between said pressure head holder and the inner ram, be provided with spring between said inner ram and the pressure head fixed cover.
Preferably, said pressure head holder and inner ram are fixed through first hexagon socket head cap screw and planchet piece, and said pressure head holder is provided with threaded connection hole.
Preferably, said inner ram and pressure head fixed cover are fixed through the gland retainer ring and second hexagon socket head cap screw.
The utility model adopts the segmented design between pressure head holder and inner ram, to be equipped with thrust bearing is set; Make it can let pressure head in the process of pressing down, have the effect of rotation and aligning; Between pressure head cover and inner ram, spring is installed simultaneously; Can let pressure head in pressing down and rigidly connect the process that contacts collector ring, have certain cushioning effect; Thereby and the function that can have adjustment to the position of collector ring reaches unanimity with the axle center of axle in the endoporus axle center when collector ring is pressed down, and guarantees that collector ring can not break in the process of pressing down.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
1. pressure head holders among the figure, 2. inner ram, 3. pressure head fixed cover, 4. thrust bearing, 5. spring, 6. gland retainer ring, 7. planchet piece, 8. first hexagon socket head cap screw, 9. threaded connection hole, 10. second hexagon socket head cap screw.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection range.
As shown in Figure 1, a kind of novel rotor collector ring press-fits pressure head, comprises the pressure head holder 1, inner ram 2 and the pressure head fixed cover 3 that connect successively, is provided with thrust bearing 4 between pressure head holder 1 and the inner ram 2, is provided with spring 5 between inner ram 2 and the pressure head fixed cover 3.Pressure head holder 1 is fixing with planchet piece 7 through first hexagon socket head cap screw 8 with inner ram 2, and pressure head holder 1 is provided with threaded connection hole 9.Inner ram 2 is fixing through the gland retainer ring 6 and second hexagon socket head cap screw 10 with pressure head fixed cover 3.
The utility model adopts the segmented design between pressure head holder and inner ram, to be equipped with thrust bearing is set; Make it can let pressure head in the process of pressing down, have the effect of rotation and aligning; Between pressure head cover and inner ram, spring is installed simultaneously; And link together through gland retainer ring (two symmetrical semicircular ring are formed); Can let pressure head in pressing down and rigidly connect the process that contacts collector ring, have certain cushioning effect, thereby and the function that can have an adjustment to the position of collector ring reach unanimity with the axle center of axle in the endoporus axle center when collector ring is pressed down, guarantee that collector ring can not break in the process of pressing down.
