Description
The utility model relates to a kind of power transmitting device.
Present inertial platform, gyro-stabilized platform and some turntable product, requiring to have used conducting ring or conductive disc power transmitting device between the unrestricted assembly of rotational freedom, but therefore this make when rotating continuously between the assembly or rotating in any angle range, all not the exception the generation moment of friction, problems such as wearing and tearing and interfering noise have relatively seriously influenced the performance of product, and have reduced the functional reliability and the working life of product.The known method that reduces power transmitting device (as conducting ring) friction problem at present is to reduce friction radius, the choose reasonable contact material, improve the crudy of contact surface, rationally determine the dustproof and lubricated etc. of contact pressure and contact site, these methods all are to go to alleviate friction again under the friction situation producing; In Su-1092-638-A, the contactless power transmitting device of a kind of gyroscopic stabilizer travelling carriage is disclosed, its objective is reliability and the dynamic characteristic of improving gyroscopic stabilizer and guider, the key of this device is to be equipped with one in the middle of the bundle conductor to reduce to curve the sine-shaped, sinusoidal spring of one-period to the center height.Both do not had the unrestricted transmission of electricity function of rotational freedom but this device solves, and had again in big angle range and rotate the problems such as moment of friction, abrasion and interfering noise that do not produce.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of unrestricted transmission of electricity function of rotational freedom that both had is provided, have again and do not produce moment of friction, the power transmitting device of wearing and tearing and interfering noise when in big angle range, rotating.
Solution of the present utility model is that the power transmitting device that is provided is to be made of unrestricted power transmitting device of rotational freedom (as conducting ring or conduction garden dish) and the restricted power transmitting device of corner (as flexible cable harness or conduction hairspring).
The unrestricted power transmitting device of rotational freedom can be the conducting ring that is made of brush assembly of electric and slip ring assembly, and the restricted power transmitting device of corner can be a flexible cable harness.The locating part that wherein is fixed on the fixture has one can reach bigger angle of rotation scope in the slotted eye of the leading-out terminal of slip ring assembly, one end of flexible cable harness and the lead-out wire of slip ring assembly join, the other end is fixed on the fixture, brush assembly of electric and fixture can be assembled to coaxially product requirement during use respectively in relative rotation on two assemblies.
The unrestricted power transmitting device of rotational freedom can also be the conductive disc that is made of disc assembly and contact assembly, and the restricted power transmitting device of corner can be a flexible cable harness, also can be conduction hairspring etc.The locating part that wherein is fixed on the part makes the relative axle of contact assembly part that a bigger angle of rotation scope be arranged with fan-shaped slotted eye on the contact assembly, disc assembly and contact assembly are bearing in respectively on the part by bearing, during use disc assembly and an axle part are assembled to product requirement respectively in relative rotation on two assemblies.When in a bigger angle range, rotating, do not produce relative rotation between the brush of conducting ring (or conductive disc) and slip ring (or disk and contact), but partly produce corresponding torsion angle by flexible cable harness, the elasticity disturbance torque that flexible cable harness (or conduction hairspring) is produced when reversing is more much smaller than the moment of friction of conducting ring (or conductive disc), problems such as wearing and tearing and interfering noise more can not occur.Above a said bigger angle range can reach ± 90 °, even bigger.When the continuous multi-turn of corner very great achievement is rotated, use conducting ring (or conductive disc) to realize the unrestricted transmission of electricity function of this rotational freedom.
Mechanical position limitation mechanism greater than 360 ° of corners also can use separately in product with power transmitting device and this mechanical position limitation Ji Ju itself that flexible cable harness constituted.
The combined type power transmitting device is compared with power transmitting devices such as present widely used conducting rings has outstanding advantage, this combined type power transmitting device had both had the unrestricted transmission of electricity function of rotational freedom, have again in a bigger angle range, to rotate and do not produce moment of friction, characteristics such as wearing and tearing and interfering noise, therefore can obviously improve performance, functional reliability and the working life of product.This combined type power transmitting device is applicable to inertial platform, products such as gyro-stabilized platform and motor.

Accompanying drawing 2 has been described another and has been comprised the combined type power transmitting device of conducting ring, its formation and action principle and accompanying drawing 1 described combined type power transmitting device roughly the same, difference is that the former has less axial dimension, the latter then has less radial dimension.
Accompanying drawing 3 has been described a combined type power transmitting device that comprises conductive disc, constitutes the conductive disc part by disc assembly (7) and contact assembly (8), has the unrestricted transmission of electricity function of rotational degree of freedom.The locating part (3) that is fixed on the part (9) makes contact assembly (8) relative axle part (9) that a bigger slewing area angle be arranged with fan-shaped slotted eye on the contact assembly (8), have on the disc assembly (7) of the concentric metal ring of some, the contact of respective amount is assembled on the contact assembly (8), disc assembly (7) and contact
Assembly (8) is bearing in respectively on the part (9) by bearing (6).During use disc assembly (7) and an axle part (9) be assembled to respectively in the product and require in relative rotation on two assemblies, when two assemblies relative to rotating continuously or corner during greater than the slewing area of locating part, disc assembly (7) and contact assembly (8) produce relative rotation.And when two assembly relative rotations were not more than above-mentioned slewing area angle, disc assembly (7) and contact assembly (8) did not just produce relative rotation, and friction problem also just do not occur, at this moment produced corresponding corner by flexible cable harness (5) (or conduction hairspring etc.).
The locating part (3) that is fixed in the accompanying drawing 4 on the part (9) at the slewing area angle that contact assembly (8) is gone up in the fan-shaped slotted eye is ± α, moment of elasticity when reversing such as (or conduction hairspring) is more much smaller with the moment of friction between the contact than disk because flexible cable harness, so when relative disc assembly (7) corner of axle part (9) is not more than the α angle, disc assembly (7) does not rotate between the contact assembly (8) relatively, just do not produced the friction problem of power transmitting device yet, when axle spare (9) rotates or corner during greater than the α angle continuously relative to disc assembly (7), locating part (3) just drives contact assembly (8) coaxial (9) and rotates simultaneously, and realize corner unrestricted transmission of electricity function by disk and contact this moment.
