Abstract
The utility model discloses a carbon brush wear indicating device for motors. The device comprises an upper carbon brush and a lower carbon brush which are arranged in a brush holder. One end of each carbon brush is provided with a spring and the other end of each carbon brush is in contact with the surface of a commutator. A sensor is arranged on one side of the brush holder. Each carbon brush is composed of a carbon brush body and a contact part capable of contacting the sensor. Each contact part is located at one end, far away from the commutator, of the corresponding carbon brush body, and the two ends of each contact part are in sliding contact with the brush holder. A gap is arranged between the sensor and each carbon brush body. The sensor is electrically connected with a controller, and the controller is electrically connected with an indicating lamp which is a bicolor indicating lamp. The carbon brush wear indicating device for motors sends a signal to the controller after contacting the carbon brushes through the sensor and controls the indicating lamp to display a corresponding color through the controller so that wear of the carbon brushes can be known. The carbon brush wear indicating device for motors has the advantages of simple structure, easy implementation, effective and reliable indication and high accuracy.
Description
Technical field
The utility model relates to a kind of carbon brush used for electric engine wear indicating device.
Background technology
Motor is commonly called as motor, refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.Motor is divided into brush motor and brushless electric machine, and wherein, in use, carbon brush has wearing and tearing to brush motor, after may wear to a certain degree, need change in time.At present, motor on market is provided with carbon brush abrasion indicating device, so that prompting operation person changes carbon brush in time, yet, existing carbon brush abrasion indicating device complex structure, manufacturing cost is high, and a motor has two carbon brush, but a carbon brush abrasion indicating device is often only installed, the accuracy of its indication is poor, when the carbon brush that carbon brush abrasion indicating device is not often installed need to be changed, cannot discover, thereby damage motor.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of carbon brush used for electric engine wear indicating device is provided, to solve original carbon brush abrasion indicating device complex structure, and the problem of indication poor accuracy.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of carbon brush used for electric engine wear indicating device, comprise carbon brush, lower carbon brush, described carbon brush is arranged in brush carrier, its one end is provided with spring, and its other end contacts with the surface of commutator, one side of described brush carrier is provided with transducer, described carbon brush consists of carbon brush body and the contact site that can contact with transducer, described contact site is the one end away from commutator in carbon brush body, and the two ends of contact site and brush carrier sliding contact, between described transducer and carbon brush body, be provided with certain gap, and transducer is electrically connected to controller, described controller is electrically connected to indicator light, described indicator light is bi-colour LED.
Further, described controller is electrically connected with power supply indicator.
Further, described carbon brush body and contact site are structure as a whole, the T-shaped structure of described carbon brush.
The beneficial effects of the utility model are, described carbon brush used for electric engine wear indicating device sends signal to controller after contacting with carbon brush by transducer, thereby by controller, control indicator light and show corresponding color understanding carbon brush abrasion situation, simple in structure, be easy to realize, and indication is effectively reliable, and accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model carbon brush used for electric engine wear indicating device.
In figure:
1, lower carbon brush; 2, commutator; 3, upper carbon brush; 4, spring; 5, brush carrier; 6, transducer; 7, power supply indicator; 8, controller; 9, indicator light; 10, carbon brush body; 11, contact site.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 1, in the present embodiment, a kind of carbon brush used for electric engine wear indicating device, comprise carbon brush 3, lower carbon brush 1, described carbon brush 1, 3 are arranged in brush carrier 5, its one end is provided with spring 4, and its other end contacts with the surface of commutator 2, one side of described brush carrier 5 is provided with transducer 6, described carbon brush 1, 3 consist of carbon brush body 10 and the contact site 11 that can contact with transducer 6, described carbon brush body 10 is structure as a whole with contact site 11, described carbon brush 1, 3 T-shaped structures, described contact site 11 is positioned at carbon brush body 10 away from one end of commutator 2, and the two ends of contact site 11 and brush carrier 5 sliding contacts, between described transducer 6 and carbon brush body 10, be provided with certain gap, and transducer 6 is electrically connected to controller 8, described controller 8 is electrically connected to indicator light 9, described indicator light 9 is bi-colour LED, described controller 8 is electrically connected with power supply indicator 7.
During carbon brush 1,3 wearing and tearing, under the pressure-acting of spring 4, all the time contact with commutator 2, meanwhile, spring 4 can make the contact site 11 of carbon brush 1,3 move down, and when may wear to while to a certain degree needing to change carbon brush 1,3, the contact site 11 of carbon brush 1,3 moves down with transducer 6 and contacts, transducer 6 passes to controller 8 by signal, and controller 8 is controlled indicator light 9 and shown corresponding color.When upper carbon brush 3 may wear to while need changing, the contact site 11 of upper carbon brush 3 touches transducer 6, and transducer 6 passes to controller 8 by signal, and controller is controlled indicator light 9, indicator light 9 is shown yellow; Instantly carbon brush 1 may wear to while needing to change, and the contact site 11 of lower carbon brush 1 touches transducer 6, and transducer 6 passes to controller 8 by signal, and controller is controlled indicator light 9, indicator light 9 is shown green; When upper carbon brush 3, lower carbon brush 1 may wear to need replacing simultaneously, the contact site 11 of upper carbon brush 3, lower carbon brush 1 touches corresponding separately transducer 6, transducer 6 passes to controller 8 by signal, and controller is controlled indicator light 9, makes indicator light 9 show half yellow half green chaos look.In addition, controller 8 is also electrically connected with power supply indicator 7, and when switching on power, controller 8 is controlled power supply indicator 7, power supply indicator 7 is shown red.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
