The slip ring can be produced in standardization, is convenient for changing parts, is simple in structure and reasonable in design and has good insulativity and safety. Each part of a rotor can accept the same power supply.

Description

Slip ring

Technical field

The utility model belongs to a kind of electric component for rotary body connection, the conveying energy and signal, is specifically related to the special-purpose slip ring of the logical machine of a kind of 160 models.

Background technology

In modern age, in the high-end field of industrial equipment, the requirement such as polynary relative motions such as revolution, rotations is arranged more.Be 360 ° of plant equipment when rotatablely moving continuously, also need polynary motion on the rotary body.Motion is arranged, just need the energy, like electric energy, the fluid pressure energy etc.Sometimes, also need the control signal source, like fiber-optic signal, high-frequency signal etc.Any rotation relatively continuously between 360 ° the electric component needs different energy sources media such as transfer function power supply, weak electric signal, light signal, air pressure, hydraulic pressure, oil pressure; To guarantee that electrical equipment can also free-moving electromechanical equipment when rotatablely moving, all must use the rotation communication apparatus.Slip ring is exactly whole to rely on elastic force overlap joint principle, roll overlap joint principle or sealing principle, and cleverly motion structure make with design of Sealing Structure, accurate part cooperate, rational selection etc., constitute reliable and stable rotation connected system.As long as slip ring is attached on the equipment of unlimited rotation, just can power source be provided to rotary body, make rotary body when infinitely rotatablely moving, can also carry out other motion or detect the working condition under the rotation status.Every field comprises the slip ring field of the logical machine of 160 models all at a large amount of slip rings that use now.

The utility model content

But the utility model provides a kind of standardized production, and part exchanging is convenient, and is simple in structure, reasonable in design, and it is good that the slip ring of good insulating, this utility model slip ring also have a fail safe, and it is identical to make the various piece of rotor accept the energy.

In order to solve the problems of the technologies described above; The utility model provides following technical scheme: slip ring comprises two slip rings that connect side by side, and the slip ring junction is provided with link slot, and the external diameter of described slip ring is 40～42mm; Internal diameter is 19～21mm; Each slip ring is provided with copper sheet, and copper sheet is symmetrical set with the shaft centre line of slip ring, and slip ring inside is filled with the phenolic plastics of insulation.Because described slip ring comprises two slip rings that connect side by side; The slip ring junction is provided with link slot; The external diameter of slip ring is 40～42mm, and internal diameter is 19～21mm, and such size not only is fit to the slip ring standard of the logical machine of 160 models; Also can make product become a kind of standard component and produce, be convenient to the replacing of part.Again owing to the shaft centre line of described copper sheet with slip ring is symmetrical set.Again because each slip ring is provided with copper sheet; Copper sheet is symmetrical set with the shaft centre line of slip ring; So the energy that slip ring makes each place of rotor obtain when to rotor the energy being provided is even; And then be rotor rotation steadily, at the uniform velocity, evenly, again because slip ring inside is filled with the phenolic plastics of insulation, so the good insulating of slip ring.Can know the simple in structure, reasonable in design of this slip ring in sum.

Further, the width of described slip ring is 8～9mm.Because the width of slip ring is 8～9mm, and is reasonable in design so the structure of slip ring is small and exquisite, practiced thrift cost.

Further; Described link slot is the arc structure of

shape indent, and its diameter is 1.5mm.Because link slot is the arc structure of

shape indent; Its diameter is 1.5mm; Thereby, slip ring disperse to have protected slip ring should not be out of shape more so receiving extraneous active force; Prolonged the use persistence of garland, the link slot of slip ring is by connecting more firmly between the slip ring simultaneously.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:

Fig. 1 is the structural representation of the special-purpose slip ring of the logical machine of the utility model embodiment 160 models.

Embodiment

As shown in Figure 1: slip ring comprises two slip rings 3 that connect side by side, and slip ring 3 junctions are provided with link slot 4, and the external diameter of described slip ring 3 is d2; The length of d2 is 40～42mm, and internal diameter is d3, and the length of d3 is 19～21mm; The width of slip ring 3 is d1; The length of d1 is 8～9mm, and each slip ring 3 is provided with copper sheet 2, and copper sheet 2 is symmetrical set with the shaft centre line of slip ring 3; Slip ring 3 inside are filled with the phenolic plastics 1 of insulation; Described link slot 4 is the arc structure of shape indent, and its diameter is d4, and the length of d4 is 1.5mm.

The special-purpose slip ring of the logical machine of 160 models like this can be produced with standard component in above-mentioned size range, is convenient to the replacing of single part, and the phenolic plastics 1 of filling insulation in the slip ring make insulating properties better, use more safe and reliable.

Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection range of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
