Description
Technical field
The present invention relates to shaft coupling fields, and in particular to a kind of shaft coupling.
Background technique
Cross axle type coupling is a kind of most common shaft coupling.Can be made using the characteristics of its structure not in same axis or
Axis dog-ear is larger or moves axially biggish two axis isogonism speed continuous rotary, and torque and movement is reliably transmitted.It can be extensively
Mechanical shafting applied to lifting, engineering transportation, mine, petroleum, ship, coal, rubber, papermaking equipment and other Heavy duty maching industries
Middle transmitting torque.Traditional shaft coupling in the case where tactical diameter is severely limited, bearing capacity is high, transmission efficiency is high,
The features such as transmitting is steady, noise is low, safe and reliable, long service life, big inclination angle allowable
Submarine optical fiber cable repeater is one of key equipment in submarine optical fiber cable communication system.And shaft coupling is then in submarine optical fiber cable
Indispensable important structure member in device equipment (aftermentioned abbreviation repeater) structure.Its repeater crosses wheel hub and sea
In cable laying construction, very important effect is played.On the complete machine structure of repeater, it is located at repeater and Fiber splice tray
Between.Its effect is entire repeater in crossing wheel hub and sea cable laying construction, plays effective protection repeater and optical fiber welding
Connect box parts.
Currently, traditional shaft coupling is very widely used in Design of Mechanical Structure.But when it is together in series to form revolution
When mechanism, in limited joint number and length limitation, to complete biggish corner and centainly be limited to.Natural flexibility and steady
Property is also centainly limited to.It is shown especially especially for repeater important.Because repeater is crossing wheel hub and sea cable laying construction
In, since overall dimensions are longer, the pulling force of both ends cable-end is larger, so that biggish bending stress can be generated, the length ruler of complete machine
Very little longer, this bending stress is then bigger.Therefore, between repeater and fused fiber splice box parts it is necessary to place one can X to
With the shaft coupling of Y-direction revolution.This requires it to need bigger inclination angle allowable, higher transmission efficiency, the more flexible peace of transmitting
Steady transmitting and lower passing noise.
