Description
Technical field
The present invention relates to a kind of multi-core fiber slip ring, particularly to a kind of multi-core fiber slip ring bevel gear system.
Background technology
Optical fiber slip ring, in order to solve the transmission problem of optical signal between two parts rotated against, is optic communication neck
One emerging study hotspot in territory.Drive mechanism is the important research content developing high quality optical fiber slip ring.
At present the most widely used technical scheme of multi-core fiber slip ring be use Dove prism to rotor light path around
Axle motion carries out reverse real-Time Compensation, thus ensures that stator terminal is in resting position and can receive rotor-end
Optical signal.This scheme is 2:1 in the same direction to the rotation ratio that drive mechanism requirement is rotor and main shaft, it addition,
For ensureing the stability of optic path, also require stable drive.
Summary of the invention
The technical problem to be solved of the present invention is to provide the stable drive ratio multi-core fiber of a kind of compact conformation
Slip ring bevel gear system.
The present invention solves above-mentioned technical problem by the following technical solutions: a kind of multi-core fiber slip ring umbrella tooth
Wheel system, including the first centre wheel being coaxially disposed, the second centre wheel and main shaft, described first centre wheel,
Second centre wheel, main shaft are tubular structure, and the centre bore of main shaft is built with Dove prism, in described first
Heart wheel, the second centre wheel are set in main shaft two ends, and are rotatably assorted with main shaft composition；In described first
One end that the heart is taken turns, the second centre wheel is relative to each other is respectively provided with a bevel gear, and the tooth ratio of two bevel gears is
1:1, the outer ring surface of described main shaft is additionally provided with turnover bevel gear, the axis of described turnover bevel gear and main shaft
Axis is vertical, and described turnover bevel gear is clipped between two bevel gears on the first centre wheel, the second centre wheel,
And engage with the two bevel gear simultaneously；Described turnover bevel gear is at least provided with two, and respectively has enough to meet the need bevel gear
Arrange along main shaft circumferencial direction uniform intervals.
It is an advantage of the current invention that: the gear train that the present invention provides can well realize the transmission of 2:1 in the same direction
Function, due to gear used order arrangement the most in the axial direction, turnover bevel gear do not have extra take the most empty
Between, therefore can greatly reduce the integral diameter of product, make product have more competitiveness.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention；

Tubular structure, the centre bore of main shaft 3 is built with Dove prism 12, described first centre wheel the 1, second center
Wheel 2 is set in main shaft 3 two ends, and is rotatably assorted with main shaft 3 composition；Described first centre wheel 1,
Two centre wheels 2 one end relative to each other is respectively provided with a bevel gear 4, and the tooth of two bevel gears 4 is than for 1:1,
Turnover bevel gear 5, the axis of described turnover bevel gear 5 and main shaft 3 it is additionally provided with on the outer ring surface of described main shaft 3
Axis vertical, described turnover bevel gear 5 is clipped in two umbrella teeth on first centre wheel the 1, second centre wheel 2
Between wheel 4, and engage with the two bevel gear 4 simultaneously；As in figure 2 it is shown, described turnover bevel gear 5 to
Being provided with two less, and each turnover bevel gear 5 is arranged along main shaft 3 circumferencial direction uniform intervals, the present embodiment is excellent
Choosing uses two turnover bevel gears 5.In actually used first centre wheel 1 and the second centre wheel 2 respectively with one
Optical fiber is connected, and when two centre wheels produce relative rotation, bevel gear mechanism can drive main shaft 3 to rotate, and
Rotary speed is the half of two centre wheel relative rotational, due to gear used order arrangement the most in the axial direction,
Turnover bevel gear 5 does not has extra to take radial space, therefore can greatly reduce the integral diameter of product,
Product is made to have more competitiveness.
