The major cycle water system radiated noise of power apparatus and nuclear power unit is the important sources of boat noise, is carried out extensively both at home and abroad
The research work of major cycle water system radiated noise is reduced, and achieves larger progress.
When major cycle water flows automatically, if major cycle water pump is rigidly connected with prime mover, water flow impact pressure can drive pump shaft to turn
It is dynamic, so as to drive prime mover to rotate together, the decline of gravity flow ability is not only resulted in, can also be driven prime mover to rotate and be caused vibrations, plus
Radiated noise of the acute major cycle water system to hull.It is therefore desirable to which clutch is on the one hand when major cycle water meets gravity flow and required
Prime mover can be departed from rapidly and be driven, on the other hand be unsatisfactory for that prime mover can be agreed with to throwing when gravity flow is required in major cycle water
Enter work, while requiring that clutch can compensate for certain radial displacement, maintain good axiality, vibration-absorbing denoising.
Utility model content
The purpose of this utility model be to provide it is a kind of depart from transmission device immediately, can compensate for larger axial displacement with
And certain radial displacement and angular displacement, overcome due to produce and assemble produce error, improve conventional clutch decentraction and
The problems such as can not departing from immediately, it can adapt to ship inclination and wave environment, reduction vibration and noise.
A kind of to depart from transmission device immediately, the device is by gland 1, trip bolt 2, roller 3, outer race 4, inside race 5, guarantor
Hold frame 6, thin-walled ball bearing 7, deep groove ball bearing 8, cover plate 9, hexagon socket cap head screw 10, bearing washer 11, inside race baffle ring
12nd, taper roll bearing 13, spring base 14 are constituted.Inside race 5 is connected by the form of interference and junction of the edges of two sheets of paper pin with steam turbine coupling
Connect, cover plate 9 is connected by the shaft end of flat key and water pump.Roller 3 is located in retainer 6, is disposed between gland 1 and inside race 5
Multigroup tension spring, tension spring is fixed on spring base 14, and spring base 14 is arranged between gland 1 and inside race 5.Outer race
4 are connected by hexagon socket cap head screw 10 with cover plate 9.Cover plate 9 is connected with inside race 5 by taper roll bearing 13.Outer seat
Circle 4 is connected with inside race 5 by deep groove ball bearing 8.Thin-walled ball bearing 7 is provided between retainer 6 and inside race 5.Gland 1 passes through
Trip bolt 2 is arranged on the end of roller 3.Bearing washer 11 is provided between thin-walled ball bearing 7 and inside race 5.Inside race baffle ring
12 are fixed by the end of screw and inside race 5.
Inside race 5 is eccentric arc structure, with the same number of arc surface of roller 3, and be centrosymmetric and be disposed with
Two positive stops.
A kind of described instant thin-walled ball bearing 7 for departing from transmission device is used for fixed retainer 6 and inside race 5, reduces
Friction torque between retainer 6 and inside race 5, it is ensured that retainer 6 will not be rocked in interior outer race, is allowed to be in and stablizes shape
State.
A kind of described instant deep groove ball bearing 8 for departing from transmission device is used for stationary outer race 4 and inside race 5, and makes
Each autorotation of energy.
The beneficial effects of the utility model are, using eccentric arc and retainer roller structure, can instantaneously enter contract
Conjunction state is transmitted moment of torsion and easily disengaged under slow-speed of revolution operating mode.When major cycle water meets gravity flow conditions, realize dynamic to original
The instant disengaging of machine, is able to maintain that the axiality of drive mechanism and compensates certain radial displacement, while overcoming due to production
The various errors produced with assembling, reduction vibration and noise.The utility model waves environment to the inclination such as ship to be had well
Adaptability.
Brief description of the drawings
Fig. 1 is that the utility model is a kind of departs from transmission structures figure immediately.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described further by embodiment.
It is a kind of to depart from transmission device immediately mainly by gland 1, trip bolt 2, roller 3, outer race 4, inside race 5, holding
Frame 6, thin-walled ball bearing 7, deep groove ball bearing 8, cover plate 9, hexagon socket cap head screw 10, bearing washer 11, inside race baffle ring 12,
Taper roll bearing 13, spring base 14 etc. are constituted.Inside race 5 is connected by the form of interference and junction of the edges of two sheets of paper pin with steam turbine coupling
Connect, cover plate 9 is connected by flat key with water pump shaft end.Roller 3 is located in retainer 6, is disposed between gland 1 and inside race 5 many
Group tension spring.Inside race 5 is eccentric arc structure, with the same number of arc surface of roller, and the arrangement that is centrosymmetric
There are two positive stops.Outer race 4 is connected by hexagon socket cap head screw 10 with cover plate 9.
A kind of described instant thin-walled ball bearing 7 for departing from transmission device is used for fixed retainer 6 and inside race 5, reduces
Friction torque between retainer and inside race, it is ensured that retainer will not be rocked in interior outer race again, is allowed to be in stable state.
A kind of described instant deep groove ball bearing 8 for departing from transmission device is used for stationary outer race 4 and inside race 5, and makes
Each autorotation of energy.
A kind of described instant taper roll bearing 13 for departing from transmission device is used for securing cover plate 9 and inside race 5.
When major cycle water is unsatisfactory for gravity flow conditions, prime mover starts, and is delivered torque in the presence of shaft coupling interior
Seat ring 5, when drive inside race 5 turns clockwise, roller 3 is moved relative to inside race 5 to the narrow one side of groove under spring force
It is dynamic, it is stuck between outer race 4 and the off-centre operation segmental arc of inside race 5, drives cover plate 9 and pump shaft rotation, now the utility model
Described device is working condition, and outer race 7 finally delivers torque to major cycle water pump by the pump shaft of major cycle water pump, and master follows
Ring water pump provides cooling water to main condenser.
