Abstract
The utility model provides a novel fixing device for a brush holder ring. The fixing device comprises a base, the brush holder ring and a pin tightening piece. The brush holder ring is provided with a pin plugging hole. One end of the pin tightening piece is fixed on the base, and the other end of the pin tightening piece is plugged in the pin plugging hole to tighten the brush holder ring. The novel fixing device for the brush holder ring can effectively overcome the problem that a plug pin of a traditional motor can be disengaged with a plug pin socket, so that the failure rate of a motor is reduced, and the normal operation of an engine is guaranteed.
Description
Technical field
The utility model relates to the parts of motor, especially relates to a kind of novel brush holder ring fixture.
Background technology
The brush holder ring of traditional Z D105 motor is that the structure with bolt-type is fixed on the support, such as Fig. 1 ~ Fig. 3.At first at brush holder ring 1 plug housing 2 is installed, the plunger of latch 3 is fixed on the support, and the pin of latch 3 is inserted on the plug housing 2, thereby realizes fixing brush holder ring 1.Yet, the impact that locomotive is in operation and can be vibrated, when brush holder ring tilted, latch can be deviate from from key seat, made to lock inefficacy.Gently then, can make motor stalling, heavy then, life danger can occur.Therefore, must address this problem.
Summary of the invention
The purpose of this utility model is: the problem for prior art exists provides a kind of novel brush holder ring fixture.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel brush holder ring fixture is characterized in that this device comprises support, brush holder ring and locks part, offer pin hole on the described brush holder ring, a described end that locks part is fixed on the support, and the other end that locks part inserts pin hole, locks brush holder ring.
The described part that locks comprises alignment pin, connecting plate, screw and locating piece, offer two holes on the described connecting plate, alignment pin inserts pin hole after passing a hole, and connecting plate is fixed on the locating piece by the screw that passes another hole, and this locating piece is welded on the support.
Described pin hole is cylindrical hole.
The aperture of described pin hole is 10 ~ 30mm.
Described aperture is 17mm.
Compared with prior art, the utility model can overcome the problem that the latch of conventional motors comes off effectively from plug housing, thereby reduces the failure rate of motor, ensures that locomotive normally moves.
