Abstract

Provided is a quick-change brush box subassembly of a generator. The brush box subassembly is composed of a brush box body, hollow plugs with fixing blocks, springs, braided copper wires and square brushes, wherein the brush box body is equipped with two transparent square cavities, each brush is placed in one end of one square cavity, one hollow plug is fixed in the other end of the square cavity via one fixing block, and connected with the brush via the braided copper wire, one spring is positioned between the brush and the hollow plug in the square cavity, anti-loosening front edges are symmetrically arranged in two side walls of the brush box body, and a contact surface of the brush and a motor rotor is an arc surface. According to the utility model, original integral structure of regulator brush of the generator is changed into the present structure in which the brush box is assembled in a split manner, thereby realizing rapid change of vulnerable parts, simple operating methods, and extremely low cost, and being economic, environment-protecting, and reliable.

Description

Generator quick change brush box sub-unit

Technical field

The utility model relates to the automobile current generator parts, be specifically a kind of can quick-replaceable generator brush box sub-unit.

Background technology

Automobile current generator is continuous duty, and it is bearing, collector ring, brush that brush motor wherein has three consumable accessorys.For collector ring and brush, main following shortcomings and the weak point of existing: 1, change complicated, the trouble of operational sequence after the collector ring wearing and tearing, the layman can not solve this fault, and accessory is hard to buy, and replacement cost is high; 2, after the adjuster sub-unit power up brush wearing and tearing, the general replacement sub-unit is dozens of yuan at least, the fee of material of units up to a hundred at most, and chip and holder part seldom recycle not environmental protection and energy saving; If 3 two whiles are serious wear all, just change more trouble; 4, in the market as long as generator breaks down and do not work (containing the consumable accessory wearing and tearing does not work), be mostly to change motor assembly, although maintenance store is saved trouble (consumable accessory is uneven) like this, caused many losses to the user; 5, the wearing and tearing of taxi trade automobile current generator consumable accessory are faster, and the member replacing frequency is higher; 6, integral type brush support will require according to brush box part technical conditions (such as high temperature resistant, wear-resisting, good insulating, fire-retardant etc.) to carry out selection, to holder part selection uneconomical (the structural strength partial properties is not again fine).

The utility model content

The utility model be to provide a kind of can quick-replaceable generator brush box sub-unit, to solve existing shortcomings and deficiencies in the above-mentioned background technology.

The technical problem that the utility model solves adopts following scheme to realize:

Generator quick change brush box sub-unit, be characterised in that, it is by brush box body, the hollow plug with fixed block, spring, flexible braiding copper cash, and square brush consists of, described brush box body is provided with two penetrating square cavities, and brush is inserted an end of square cavity, and hollow plug is fixed on the other end of square cavity by fixed block, hollow plug is connected with brush by the braiding copper coin, and described spring places square cavity interior between brush and hollow plug.

In the utility model, be symmetrically arranged with locking seam in the two side of described brush box body, when inserting socket, can play positioning action, can prevent that again brush box from coming off from socket.

In the utility model, the contact-making surface of described brush and rotor is arcwall face.

Beneficial effect: the utility model changes original dynamo governor brush monolithic construction present brush box into and is designed to the split package assembly, can realize the quick-replaceable consumable accessory, and method of operation is easy, and economy, environmental protection, reliable, and cost is extremely low.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail as follows:

Shown in Fig. 1-5, generator quick change brush box sub-unit, by brush box body 1, the hollow plug 3 with fixed block 2, spring 4, flexible braiding copper cash 5, and square brush 6 consists of, described brush box body is provided with two penetrating square cavities 8, square brush is inserted an end of square cavity, hollow plug is fixed on the other end of square cavity by fixed block, hollow plug is connected with brush by the braiding copper coin, and described spring places square cavity interior between brush and hollow plug.The contact-making surface of described brush and rotor is arcwall face, can better guarantee that brush contacts with the effective of rotor cover, be symmetrically arranged with locking seam in the two side of brush box body, after the utility model inserted socket, locking seam can prevent that the utility model from coming off from socket.

During use, the utility model inserted in the supporting socket pre-set get final product, at this moment, hollow plug contacts with power supply coupling part in the socket, and brush contacts with generator amature, thus the circuit of formation connection.

Design principle of the present utility model:

1, brush box part is designed to separately split formula assembly, and support and brush box are respectively for the features selection, and it is better to combine rear performance, more economical, more environmental protection;

2, holder part is designed to the standard socket interface, brush box part energy quick assembly and disassembly, and can locate reliably, be designed with locking seam;

3, it is easy to wear that the carbon brush material is wanted the copper band of relative collector ring, and each so all is that carbon brush abrasion is fast, and copper band little wear, this point have been control, and material might as well solve separately;

4, split type brush box is done the life-span test, the wear-out period (how many ten thousand milimeter numbers) of measuring brush, regularly do maintenance to generator, change the brush box consumable accessory;

5, low cost of manufacture, brush box component costs only need about 3 yuan;

6, method of operation is easy, and economy, environmental protection, and is reliable;

7, standardized production brush box accessory solves the versatility of this type.
