Abstract

The utility model relates to a motor bearing sliding loop, which comprises a bearing outer ring and a bearing inner loop, wherein, a plurality of the electric conduction balls are densely distributed in the gap between the bearing inner loop and the bearing outer loop and contacted with the inner loop and the outer loop. The utility model is characterized in that the bearing outer loop comprises two long interleaved and distributed insulators and two short electric conductors, and the bearing inner loop comprises two short insulators and two long electric conductors. The carbon brush is not required for the motor bearing sliding loop, so the friction resistance produced between the carbon brush and the sliding loop is eliminated, therefore the motor period of usage is prolonged, the motor rotation speed is increased and the motor efficiency is improved.

Description

A kind of bearing-type slip ring of motor
Technical field
The utility model relates to a kind of slip ring of motor, the bearing-type slip ring of a kind of motor of more specifically saying so.
Background technology
Traditional motor, no matter be generator or motor, on all having carbon brush and being contained in rotating shaft and the slip ring that contacts with carbon brush, during work, carbon brush and slip ring will produce friction, this friction not only can make the carbon brush wearing and tearing, become consumable accessory, the more important thing is that rotating shaft will overcome the extra work done of this frictional force, and efficiency of motor is reduced.
Summary of the invention
The purpose of this utility model provides a kind of bearing-type slip ring of high efficiency motor.
In order to realize above-mentioned purpose, the bearing-type slip ring of the motor that is provided, comprise outer race and bearing inner ring, in the gap between outer race and the bearing inner ring, be densely covered with the conduction ball that contacts with the two, its design feature is that outer race is to be made of the two segment length's insulators that are interspersed and two sections short electric conductors, and bearing inner ring is to be made of two sections that are interspersed short insulators and two segment length's electric conductors.
During installation, bearing-type slip ring provided by the utility model is fixed in the rotating shaft, is connected to the connection lead respectively on two sections short electric conductors of outer race, be connected to the coil that is arranged in magnetic field on two segment length's electric conductors of bearing inner ring, coil is wrapped in the rotating shaft.
The operation principle of the bearing-type slip ring of motor provided by the utility model is as follows:
1, for motor, electric current flows out from the anode of power supply, lack electric conductor, another root connection lead through wherein a connection lead, one section short electric conductor wherein, the conduction ball of corresponding position, segment length's electric conductor wherein, coil, another segment length's electric conductor, the conduction ball of corresponding position, another section successively, flow back into the negative terminal of power supply, according to left hand rule, be arranged in the charged coil in magnetic field and just produce moment, coil is rotated, the rotation of coil drives the rotating shaft rotation, and the rotation of rotating shaft drives other parts work;
2, for generator, prime mover drives rotating shaft and rotates, the coil that is wrapped in the rotating shaft rotates thereupon, the rotation of coil makes coil cutting magnetic line, produce induced electromotive force, this induced electromotive force is outwards exported electric energy through the conduction ball of long electric conductor, corresponding position, short electric conductor, pairing connection lead respectively by the two ends of coil.
Learn that by top narration the bearing-type slip ring of motor provided by the utility model is owing to saved carbon brush, removed the frictional resistance that carbon brush and slip ring produced, not only prolong the useful life of parts, and increased the rotating speed of rotor, improved efficiency of motor.
Description of drawings
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, and what wherein accompanying drawing drew is the structural representation of the bearing-type slip ring of the described motor of embodiment.
Among the figure: 1 is outer race, and 1-1 wherein is that long insulator, 1-2 are short electric conductors, and 2 is bearing inner ring, and 2-1 wherein is that short insulator, 2-2 are long electric conductors, and 3 are the conduction ball, and 4 is coil, and 5 for connecting lead, and 6 is magnetic field.
Embodiment
With reference to accompanying drawing, the bearing-type slip ring of the described motor of embodiment, comprise outer race 1 and bearing inner ring 2, in the gap between outer race 1 and the bearing inner ring 2, be densely covered with the conduction ball 3 that contacts with the two, outer race 1 is to be made of the two segment length's insulator 1-1 that are interspersed and two sections short electric conductor 1-2, and bearing inner ring 2 is to be made of two sections that are interspersed short insulator 2-1 and two segment length's electric conductor 2-2.During installation, the bearing-type slip ring of this motor is fixed in the rotating shaft, be connected to connection lead 5 respectively on two sections short electric conductor 1-2 of outer race 1, be connected to the coil 4 that is arranged in magnetic field 6 on two segment length's electric conductor 2-2 of bearing inner ring 2, coil 4 is wrapped in the rotating shaft.
