Description
Technical field
The present invention relates to aero-engine fields, particularly, are related to a kind of mechanical contrate-gear-type clutch.
Background technique
The clutch used in existing starter reduction device is mostly freewheel clutch, the structural representation of the type clutch
Figure includes mainly outer ring 1 (housing usually makees active member), (inner shaft usually makees driven member to inner ring 2 as shown in attached drawing Fig. 1
Part), groups of sway brace 3, interior retainer 4, outer retainer 5, spring 6 and bearing etc., when work, pass through groups of sway brace
3 wedging between inner ring 2, outer ring 1 acts on to transmit torque.
When the revolving speed of outer ring 1 counterclockwise be greater than inner ring 2 revolving speed when, spring 6 tensile force and sway brace 3 with
Under frictional force effect between 2 joint surface of outer ring 1 and inner ring, sway brace 3 will be rotated counterclockwise around the center of its own, due to oblique
The size b of bracer 3 is greater than the radial distance a between outer ring 1 and inner ring 2, and sway brace 3 is just wedged between inner ring 2, outer ring 1, thus
It is latched outer ring 1 and inner ring 2 mutually, clutch is in drive state；When the revolving speed of inner ring 2 counterclockwise is greater than outer ring 1
Revolving speed when, the frictional force between sway brace 3 and inner ring 2 and outer ring 1 overcomes the tensile force of spring 6 so that sway brace 3 surround its
The center of itself rotates in a clockwise direction, and because the size c of sway brace 3 is less than the radial distance a between two rings, sway brace 3 is just
It is detached from wedging, inner ring 2, outer ring 1 move independently of one another, and clutch, which is in, surmounts state, and when surmounting state, spring 6 is forced tiltedly
Bracer 3 is contacted with two rings.
1) the contact friction torsion pass due to the torsion pass of the type clutch by groups of sway brace with inner and outer ring, worked
Cheng Zhong, situations such as be easy to causeing the spot corrosion of sway brace and inner and outer ring contact surface to peel off；2) work of clutch depends in groups
Sway brace, therefore the service performance of clutch to the design of sway brace, manufacture and assembly have very high technical requirements, diagonal brace
The quality of block has important influence to the performance of clutch；3) in the engagement of clutch and disengagement, the tensile force of spring is risen
Important function, when the tensile force of spring is uneven or too small, will result in clutch the abnormal conditions such as can not disengage in time；
4) parts such as spring, retainer in the clutch are easy to appear crackle or crack conditions under bad working environments, thus influence from
The normal use of clutch, so that the poor reliability of clutch.
